DESCRIPTION JPS57154997
Item 1 Name of invention
Electrokinetic speaker
DETAILED DESCRIPTION OF THE INVENTION The present invention is an assassination that
facilitates coil termination processing of NU electronic speakers. Conventional behavior 7. As
shown in FIG. A coil bonded to the IK moving plate 1. Frame supporting diaphragm 1 3.
Permanent magnet 4. The end of the coil 2 is connected to the lead substrate β on the frame 3
through the through hole 7 of the frame 2 through the through hole 7 of the frame 2. However,
this method of first-hand treatment not only requires a large number of steps for passing the coil
wire through the through hole, but also causes a drop in yield due to wire breakage. It was also a
part that makes it difficult to automate. The present invention is intended to improve upon the
above-mentioned drawbacks, and the J17i moving plate to which the coil is adhered is set on the
J return moving plate receiving seat, and is swallowed by the lead substrate to form a diaphragm
unit. The purpose of this is to make it easy to carry out the processing of the reduction treatment,
and to make it self-reliable. EndPage: 1 or less, the present invention will be described in detail
according to the drawings. FIG. 1'S2 is a cross-sectional view of an electrokinetic speaker family i
':: It47 switch according to the present invention, wherein 6.431'J is the lower plane "11." The
diaphragm unit is a diaphragm 1. Coil 2.4 swing plate reception seat 9. The lead substrate 10 is
formed to be t′η. The diaphragm 1 to which the coil 2 is adhered is held by the 1b · 3 moving
plate support 9 and the lead substrate 10 at its periphery, and the diaphragm 11 and the lead are
fixed by caulking the projection 11 provided on the diaphragm support 9 The substrate 10 is
held. This letter 11 I! At 4, the coil end is processed by welding or soldering on the pattern of the
lead substrate 10. FIG. 4 shows a movement 'rj assembled from the diaphragm unit shown in FIG.
2 and FIG. 3121 and a cross section t'-/ I of the speaker, and FIG. 5 is a bottom plan view of the

same. フレーム3. Permanent magnet 4. Magnetic core 5. The core unit is made 1irj by the
plate 6. The magnetic core 5 and the plate 6 have a groove for receiving the cylindrical
permanent stone 4 and permanently 7 + 2. E absorption of stone 4 [held by force. The frame 3 is
bonded to the magnetic core 5 by bonding or bonding. With the diaphragm unit? The
protrusions 1 and 12 provided on the lil core unit plate receiving seat 9 are joined in a root
region by caulking the frame 6. FIG. 6 shows another embodiment of the present invention (a
cross-sectional view of a b-type speaker, in which the lead and the bowl 16 extend along the
diaphragm 1 to the vicinity of the film).
In this case, it is characterized in that the coil wire can be terminated near the coil 2. As
described above, when the electrodynamic speaker according to the present invention is attached
to the device, the electronic circuit portion can be screwed to the circuit board or the like by
using the hole on the lead substrate 10 (or 16) protruding from the diaphragm seat 9 At the
same time, the electrical connection with can be easily obtained. As described above, in the case
of the present invention, the diaphragm unit is formed by the coil, the diaphragm, the diaphragm
receiving seat, and the lead substrate 1) / i, and the end of the coil is processed on the lead
substrate pattern. By combining with the unit, it became possible to automate the coil terminal
processing, and it was possible to measure the improvement of production and residence.
Further, as shown in FIG. 5, when the diaphragm diameter of the diaphragm is large, the
chattering noise due to wire displacement is eliminated by performing the end processing J ′ ′
jj in the vicinity of the coil by extending the lead substrate. Therefore, the object of the present
invention 1 () 1 is sufficiently achieved, and the effect is practically great. DESCRIPTION OF THE
PREFERRED EMBODIMENT FIG. 1 is a view of a conventional dynamic 1d speaker. 2 and 3 are a
sectional view and a plan view, respectively, of an electrodynamic speaker vibration 4 unit
according to the present invention. FIG. 4 is a sectional view s ';-)') showing an embodiment of the
electrodynamic speaker according to the present invention, and FIG. 4 is a plan view thereof. FIG.
6 is a cross-sectional view of an electrodynamic speaker showing another embodiment of the
present invention. 1 · · · Diaphragm 2 · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · · Permanent magnet
