DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of a loudspeaker system. In the conventional speaker system, even if the damping factor of the
amplifier for driving the speaker is increased, the resistance of the wiring in the speaker system
limits the braking of the speaker viewed from the amplifier side. The present invention is
considered to have the above-mentioned effect, and by providing a feedback terminal separately
from the drive coil of the speaker, by using the feedback terminal, remote sinking may be
performed by remote sensing 'Z, 7-. It is a turtle that aims to provide a speaker system that can
improve the damping factor due to the resistance of the wiring inside the speaker system.
Hereinafter, the present invention will be described by way of examples. FIG. 1 is an explanatory
view of an embodiment of the present invention. 1 is a speaker main body, 2 is a speaker drive
coil. The both ends of the speaker drive coil 2 and the speaker input terminals 3 and 4 are
connected to each other, and the both ends of the speaker drive coil 2 are connected to the
feedback terminal 5 and the ? clause separately. Therefore, for example, as shown in FIG. 2, the
audio amplifier 10 has, for example, an amplifier 11, the output of the amplifier 11 is connected
to the output terminal 12, and the resistors R1, R2, I'L3 and R4 are connected to the output of
the amplifier 11. The output circuit of the amplifier 10 is divided by a first series circuit of the

resistors R and R2 and a second series circuit of the resistors R3 and R4. On the other hand,
connection of the resistors R1 and 82-(2) 4. The point 0 is connected to the sensor terminal 13,
and the connection point between the resistors R3 and R4 is connected to the sensor terminal
14. One end 15 of the amplifier 11 is the other output terminal. The output terminal 12 is
connected to the speaker input terminal via the speaker cord 16, the output terminal 15 is
connected to the speaker input terminal 4 via the speaker cord 17, and the sensor terminal 13 is
connected to the feedback terminal 5 via the sensor cord 18. The sensor terminal 14 is
connected to the feedback terminal 6 by a sensor cord 19. Thus, the DC resistance and the
inductance of the speaker cord 16.17 in which a large current flows is included in the feedback
loop, and further, a large current flows between both ends of the speaker drive coil 20 and the
speaker input terminals 3 and 4. Since the DC resistance and the inductance between them are
also included in the feedback loop, the damping of the loudspeaker is significantly improved. FIG.
3 is an explanatory view of a speaker system according to another embodiment of the present
invention.
The present embodiment is an example in the case of a 3-way speaker system. (3) 021 represents
a woofer, 22 represents a squawker, 23 represents a try, 24 represents a woofer drive coil, 25
represents a squawker drive coil, and 26 represents a tweeter drive coil. Further, 27 is a speaker
system input terminal connected to one end of the woofer drive coil 24, and 28 is a speaker
input terminal connected to the other end of the woofer drive coil 24. Further, 29 is a feedback
terminal connected to one end of the woofer drive coil, and 30 is a feedback terminal connected
to the other end of the woofer drive coil. Reference numerals 31 and 32 denote a scoker network
and a tweeter network. The scoker network 31 and the tweeter network 32 are configured such
that input signals are applied from both ends of the woofer drive coil 240. Therefore, the remote
sensing can be configured in the same manner as shown in FIG. In this case, the DC resistance
and inductance of the speaker cord and the DC resistance and inductance of the cord connected
between the speaker input terminal 27.28 and both ends of the woofer drive coil are
incorporated in the feedback loop of the amplifier 11. This is equivalent to the direct connection
of the woofer drive coil 24 directly to the output end of the amplifier 11, and the damping of the
speaker is greatly improved. In this case, since the current flowing to the scarifier 22 and the tow
eater 23 is small compared to the current flowing to the woofer 21, the resistance and
inductance of the wiring between the woofer drive coil 24 and the scarca network 31 and the
tweater network 32 are The impact of can be small and ignored. As described above, according
to the present invention, when the remote sensing method is used using the speaker system of
the present invention, the internal wiring between the speaker input terminal and the speaker
drive coil is also incorporated in the feedback loop of the amplifier. Braking is improved and the
sound quality deterioration due to the internal wiring of the speaker is also eliminated.
