The present invention relates to loudspeaker transducers, and more particularly to loudspeaker
magnet structures having channels in the loudspeaker transducer.
[0003]
Sound reproduction devices such as loudspeakers are widely used in many different technical
fields, including both consumption and industrial fields.
Loudspeakers usually include one or more driver units in a box.
These driver units are commonly known as "loudspeaker drivers", "drivers", "loudspeaker
converters" or "converters". A loudspeaker transducer, which combines mechanical and electrical
components, converts an electrical signal (which is typically a sound) into mechanical energy that
generates sound waves in an ambient sound field corresponding to the electrical signal. The high
speed vibration of the flexible diaphragm in the transducer converts the changed electrical
energy into corresponding acoustic energy (i.e. sound waves).
[0004]
Loudspeaker converters generally consist of two common structural types. The first construction
type is a conventional double suspension driver construction, in which the diaphragm of this
loudspeaker converter is shaped like a cone, the diameter of which is sufficiently larger than the
voice coil. As an example, a known representative dual suspension loudspeaker transducer 100 is
shown in FIGS. 1A and 1B. FIG. 1A is a perspective view and FIG. 1B is a cross-sectional view of a
known loudspeaker transducer 100. The illustrated loudspeaker converter 100 is an example of
implementing a moving coil electrodynamic piston driver, also commonly known as a "dynamic
speaker". The known loudspeaker converter 100 includes a diaphragm 102, a frame 104, a
surround 106, a front plate 108, a magnet 110, a back plate 112, a voice coil 114, a winding
form 116, a central column 118, a vent 120, a gap 122, and a spider 124. And optional dust cap
126 may be included.
[0005]

In this example, the loudspeaker converter 100 is comprised of a diaphragm 102 (also known as
a "cone") attached to a frame 104 (also known as a "basket") via a surround 106. Attached to the
back of the diaphragm 102 is a wire coil (shown as a voice coil 114), which is wound around a
cylindrical extension of the diaphragm 102, shown as a former 116. Those skilled in the art will
appreciate that the combination of voice coil 114 and form 116 is in fact also simply referred to
as the "voice coil". The former 116 is connected to the frame 104 via the spider 124. The
combination of the surround 106 and the spider 124 constitutes a suspension system of the
diaphragm 102. Both the spider 124 and the surround 106 function as a frame and connect
between the former 122 and the frame 104 and between the diaphragm 102 and the frame 104,
respectively, and are usually made of a flexible material. Ru. The suspension system provides
rigidity to the diaphragm 102 and also functions to air seal the transducer 100. The structure of
the voice coil 114, the form 122, and the diaphragm 102 inside the frame 104 via the
suspension system is roughly determined by the structure and size of the diaphragm 102 relative
to the voice coil 114 and form 122. As an example of operation, the diaphragm 102 functions as
a piston that delivers air and generates sound waves.
[0006]
The loudspeaker transducer 100 is also comprised of a magnet 110, a front plate 108, a back
plate 112, and a central post 118 (also known as a "pole piece"). The front plate 108, the back
plate 112, and the central post 118 are typically formed of iron, steel, or similar water-permeable
materials and form a magnetic circuit with the magnet 110, which is usually a permanent
magnet. Both the front plate 108 and the back plate 112 are normally annular. The magnet 110
is cylindrical and annular, and the central column 118 is a hollow cylinder located inside the
magnet 110 and extends between the front plate 108 and the back plate 112. At the end of the
central column 118, a rim is formed extending therefrom substantially perpendicularly to the
front plate. The lip extends outwardly from the central post 118 toward the front plate 108 to
form a gap 122. The front plate 108 and the central column 118 roughly form a circular gap
122 in the magnetic circuit. As a result, the voice coil 114 and the winding form 116 are
suspended inside the gap 122, are freely movable back and forth inside the gap 122, and the
spider 124 acts so as to be located in the middle of the gap 122. The central post 118 may
optionally include a cylindrical vent 120, which suppresses pressure build up behind the
diaphragm 102 in the magnet assembly and cools the voice coil 114. If a vent 120 is formed, it
may be provided with an optional dust cap 126 (also known as a "screen") to block debris
entering through the vent 120.
[0007]
11-05-2019

As an example of operation, when the electrical signal from the amplifier passes through the
voice coil 114, the voice coil 114 and the form 122 change to an electromagnet. Depending on
the direction of current flow through the voice coil 114, the north and south poles of the
magnetic field generated by the voice coil 114 are located at one end of the voice coil 114 or
other member. Similarly, when the magnet 110 also has an N pole and an S pole, and the N pole
and S pole of the two magnetic fields are aligned in a line (N pole-N pole and S pole-S pole), the
magnetic field is a voice coil. The voice coil 114 is pulled inward when the 114 (and the
diaphragm 102 attached to it) is pushed outward, and when aligned in the opposite position (N
pole-S pole and S pole-N pole).
[0008]
The second type of driver structure is an end-drive diaphragm type driver. In this structure, the
diameter of the diaphragm and the diameter of the voice coil are approximately equal. As a
result, the outer end of the diaphragm is attached to the diaphragm to form a diaphragm
assembly. The assembly is then attached to the voice coil. The surround suspension assembly
extends outward to connect the assembly and the frame. This end-drive diaphragm type driver
structure is often used for small speaker assemblies such as tweeters, and even mid-range
speakers. An example of an end-drive diaphragm type driver is described by Clayton C. et al. No.
7,167,573 (issued Jan. 23, 2007), entitled "FULL RANGE LOUDSPEAKER," which is incorporated
herein by reference in its entirety.
[0009]
One of the problems common to small loudspeakers is that the small size of the loudspeaker
makes it difficult to achieve an acceptable low frequency response. Because, to achieve low
frequency, the loudspeaker needs to exhaust more air volume, and to reduce the stiffness of the
suspension to maintain the low resonance corresponding to the light mass of the small driver
Because there is The air volume that the loudspeaker can discharge depends on the area of the
diaphragm and the range of motion that the suspension allows, i.e. the amount of vibrational
displacement or volume displacement of the loudspeaker. Furthermore, it is desirable for the
stiffness to be minimal as the rigid suspension reduces the motion of the pre-set diaphragm.
Because small loudspeakers have small diaphragms and rigid suspensions, volumetric
displacement, and hence their operation, is limited according to their ability to produce
loudspeakers with very low stiffness and high displacement capabilities.

[0010]
For efficient operation, the suspension system in a small loudspeaker, used for end-drive
diaphragm type loudspeakers etc., essentially suppresses the oscillatory motion in a linear path
so that the voice coil contacts the surrounding structure It is necessary to allow the maximum
amplitude required for the vibration while not Therefore, the surround suspension needs to
suppress any tilt, oscillation or other external vibration of the diaphragm while allowing the
maximum possible amplitude of the desired vibration. A common problem with end-driven
loudspeakers of current construction is that the diaphragm blocks the magnet air gap, making
accurate alignment of the components during manufacture difficult. That is, the position of the
voice coil relative to the motor may be inaccurate because it is necessary to remove all of the
adjustment gauges prior to deployment of the diaphragm / coil assembly. This is known as a
"blind" assembly.
[0011]
A further common problem with current structure loudspeakers is that spurious vibrations in
parts of the surround suspension occur at high audio frequencies. Since these spurious vibrations
can be transmitted to the diaphragm through the suspension, the high frequency performance of
the speaker is degraded. Also, with current loudspeaker structures, the small size limits the
maximum amplitude of vibration, while short diameter speakers suppress low frequency
response. Furthermore, in the smaller loudspeaker frame structures, these loudspeakers are not
configured to be thin enough to be used in laptop and electronic tablet devices.
[0012]
Therefore, minimizing the effects of the suspension system's spurious oscillations on the
diaphragm and increasing the amount of displacement of the voice coil / diaphragm assembly to
achieve low frequency response in a short diameter loudspeaker system, laptop, There is a need
for a thin loudspeaker structure suitable for use in electronic tablets and other thin devices.

The annular outer magnet has an outer diameter and an inner diameter, the inner diameter
defining a hollow circular center inside the annular outer magnet. The diameter of the circular
inner magnet is shorter than the inner diameter of the annular outer magnet, and is concentric

To illustrate in more detail, an exploded view of an embodiment of a loudspeaker converter 200
according to the invention is shown in FIG. Loudspeaker converter 200 is generally circular in
structure and may include a diaphragm 202, a first magnet assembly 204, and a second magnet
assembly 206 positioned between top plate 208 and bottom plate 210. As an example, the first
magnet assembly 204, the second magnet assembly 206, the top plate 208, and the bottom plate
210 may be attached using, for example, a two-part epoxy (ie physically connected or coupled
together) ). Loudspeaker converter 200 may further include a surround suspension 212, which
floats diaphragm 202, and a voice coil 214, for a pair of circuits (also known as tensile leads)
from which voice coil 214 extends outwardly. A wire 216 is provided. The voice coil 214 is a
winding of the circuit wire 216 surrounding the winding form 218.
[0025]
Those skilled in the art will appreciate that although the diaphragm 202 shown is a generally flat
circular configuration, it may be other configurations, such as concave or convex. The flat
diaphragm 202 is used to lower the height of the loudspeaker converter 200 and is used for
small applications such as portable, laptops, networks, tablet computers, and loudspeakers
designed for mobile devices. Allowing for a low profile package, which is often desired. The
diaphragm 202 may be formed of any suitable rigid material, such as titanium, aluminum or
other metals, plastics, non-metallic materials such as impregnated paper, reinforced paper, or
various impregnated fibers. A raised structure, such as a flower structure 218, may be embossed
on the top of the diaphragm 202 to provide additional rigidity.
[0026]
The first magnet assembly 204 may be generally circular in structure and may include a circular
inner magnet 220 and annular outer magnets 222 and 224. The circular inner magnet 220 and
11-05-2019
10
the annular outer magnets 222 and 224 may be any known magnetic material commonly used
for loudspeaker transducers. When assembled, the circular inner magnet 220 and the annular
outer magnets 222 and 224 may be arranged concentrically with a gap between each other, to
allow the voice coil 214 and the winding form 218 to pass, as described in further detail below.
The air gap 226 of the first magnet assembly is defined. Further, the annular outer magnets 222
and 224 may be split, as shown, to define one or more channels 228 through which the circuit
leads 216 from the voice coil 214 pass out of the loudspeaker transducer 200. While FIG. 1
shows annular outer magnets 222 and 224 defining two channels 228, in this example only one
annular outer magnet may be used, with only one or no channels. Those skilled in the art will
understand.
[0027]
Following the first magnet assembly 204, a second magnet assembly 206 may be described,
which may have a generally circular configuration and may include a circular inner permanent
magnet 230 and an annular outer permanent magnet 232. The inner permanent magnet 230
and the annular outer permanent magnet 232 may be formed of any known magnetic material
commonly used in loudspeaker transducers. When assembled, the inner permanent magnet 230
and the annular outer permanent magnet 232 may be arranged concentrically with a gap
between each other, and the air gap 234 of the second magnet assembly for the voice coil 214
and the winding form 218 to pass through. Define
[0028]
In another example, the annular outer permanent magnet 232 can be split into annulus to define
one or more channels (not shown) that will be acoustic holes. By forming the acoustic holes, the
acoustic pressure from the back of the diaphragm 202 can be transmitted to a speaker "box" or
enclosure (not shown), which is typically a bass reflex or acoustic buffer system. Channels (not
shown) may include inlet and outlet ends, which may be circular, chamfered, or other structures
that propagate pressure waves from the air gap 234 of the second magnet assembly to the
speaker enclosure.
[0029]
Referring to the top plate 208, this may be a generally circular structure and may include a
11-05-2019
11
circular inner top plate 236 and an annular outer top plate 238. The top plate 208 may be
formed of magnetic soft iron, steel, or any other similar water-permeable material suitable to
function as a top plate, and includes the first magnet assembly 204, the inner permanent magnet
230, and the bottom plate 210. Form a magnetic circuit. When assembled, the circular inner top
plate 236 and the annular outer top plate 238 may be concentrically spaced apart from one
another to define a gap 240 in the top plate for the voice coil 214 and the winding form 218 to
pass through. .
[0030]
The bottom plate 210 may have a generally circular structure and may include one or more
radially disposed bottom plate slots 242 extending inwardly from the outer periphery of the
bottom plate 210. The bottom plate 210 may be formed of magnetic soft iron, steel, or any other
similar water-permeable material suitable to function as a bottom plate, along with the first
magnet assembly 204, the inner permanent magnet 230, and the top plate 208. Form a magnetic
circuit.
[0031]
An exploded perspective view illustrating the first magnet assembly 204 and the second magnet
assembly 206 of the loudspeaker transducer 200 (shown in FIG. 2) is shown in FIG. The first
magnet assembly 204 is a converting magnet for a thin loudspeaker transducer. The first magnet
assembly 204 may include an annular outer magnet having an outer circumference, an outer
diameter and an inner diameter. The inner diameter defines a hollow circular center inside the
annular outer magnet, and the difference in length between the diameter of the circular inner
magnet and the inner diameter of the annular outer magnet defines the air gap of the annular
first magnet assembly. The annular outer magnet includes one or more channels extending
inwardly from the outer periphery of the annular outer magnet toward the air gap of the first
magnet assembly, wherein the air gap of the first magnet assembly is configured to receive the
voice coil The channel is configured to pass the circuit wire from the voice coil from the
transducing magnet to the external device.
[0032]
More specifically, although the annular outer magnets 222 and 224 in FIG. 3 are two separate
11-05-2019
12
magnets, one skilled in the art will further appreciate that they may be coupled to form one
annular outer magnet (not shown). to understand. The resulting one annular outer magnet (not
shown) has only one channel rather than the two channels shown in FIG. Similarly, annular outer
magnets 222 and 224 may be divided into three or more portions (in the shape shown in FIG. 3)
in which three or more channels 228 are formed in the shape shown in FIG. Furthermore, as
mentioned above, the annular outer permanent magnet 232 of the second magnet assembly 206
may be divided into annulus to define one or more channels (not shown) that will be acoustic
holes.
[0033]
Referring to FIGS. 4A and 4B, a top view of the magnet assembly of loudspeaker transducer 200
(shown in FIG. 2) is shown in FIG. 4A. This top view shows the first magnet assembly 204. As
shown, the diameter of the first magnet assembly 204 is somewhat smaller than the diameter of
the second magnet assembly 206, and the channel 228 defined between the annular outer
magnet 222 portion and the magnet 224 portion (see FIG. 2 and extending outward from the
cavity 226 of the first magnet assembly (as defined in FIG. 3), for example, tangentially to the
diameter of the cavity 226 of the first magnet assembly. Those skilled in the art will appreciate
that the entire air gap 400 is defined by the combination of the air gap 226 of the first magnet
assembly, the air gap 240 of the top plate, and the air gap 234 of the second magnet assembly.
The entire air gap 400 further defines a cylindrical annular cavity, which starts at the top of the
first magnet assembly 204 and continues to the top of the bottom plate 210. At the bottom of the
entire void 400, an open area defined by the cylindrical annular cavity of the entire void 400 and
the radially arranged slots 242 of the bottom plate 210 is formed.
[0034]
A bottom view of the bottom plate 210 of the loudspeaker converter 200 (shown in FIG. 2) is
shown in FIG. 4B. As shown, the slots 242 radially disposed in the bottom plate 210 extend
inwardly from the outer periphery of the bottom plate 210 toward its center. In this example, an
air passage 402 connecting the individual slots 242 and the entire air gap 400 is formed.
[0035]
A cross-sectional view of the loudspeaker converter 200 of FIG. 2 is shown in FIG. In FIG. 5, the
11-05-2019
13
bottom plate 210 supports a stack that includes cylindrical permanent magnets (i.e., the second
magnet assembly 206), the top plate 208, and the first magnet assembly 204, as shown. In this
example, the top plate 208 and the first magnet assembly 204 (at a position above the top plate
208) are located above the second magnet assembly 206 in the stack.
[0036]
As shown in FIG. 5, since the diameter of the circular inner magnet 220 matches the diameter of
the circular inner top plate 236 and the inner permanent magnet 230, the air gap 226 of the first
magnet assembly, the air gap 240 of the upper plate, and the second The air gaps 234 of the
magnet assembly are arranged in a row and define the entire air gap 400. Thus, the entire air
gap 400 is between the circular inner magnet 220, the annular outer magnet 224, the circular
inner top plate 236, the annular outer top plate 238, the circular inner permanent magnet 230,
and the annular outer permanent magnet 232, respectively. It is an annular space formed. Thus,
the entire air gap 400 is a "magnet air gap". As a result, the voice coil 214 and the winding form
