Specification 18 Title of Invention
3. Detailed Description of the Invention The present invention relates to a speaker for facilitating
wiring for a voice coil. As is well known in moving coil type speakers. Although it is necessary to
wire the voice coil, conventionally, a method of drawing out a pair of tinsel wires from the voice
coil and connecting a lead wire for wiring to this has been used. However, in this method, the
drawing direction is restricted due to the necessity of fixing the relay point of the tinsel wire. By
the way, in a multi-point drive type speaker, it is necessary to connect a plurality of voice coils of
a plurality of magnetic circuits in series, such as a structure in which one diaphragm is
simultaneously driven by a plurality of magnetic circuits There is. Then when C is the wiring
method for each voice coil. Since the method described above has a restriction in the drawing
direction of the tinsel wire, the wiring for connecting to the above series becomes very Vccontaminated, and many lead wires are complicated. It is an object of the present invention to
provide a VCWX invention, which is not capable of facilitating the above wiring. An embodiment
91 in which the present invention is applied to a four-point drive flat panel speaker will be
described below with reference to the drawings. 1 to 6 show an example of a laugh. The vibration
system is, for example, a square flat diaphragm (1), an edge (2) attached to the outer periphery of
the diaphragm (1), and a diaphragm (n * 4 voice coil bobbins attached to the back of the
diaphragm (31 g, a voice coil (4) n-wound around each of its bobbins (3), and an fL-tamper with a
d-n coupling to each of the bobbins (3)) And 91) EndPage: 1). "By driving the position R of the
node of the specific divided vibration of the diaphragm, the divided vibration can be removed.
From the feature of the multipoint drive system that says " The four voice coil bobbins (3) are
attached to the four nodes of the divided vibration of the diaphragm fi +. On the other hand, the
drive system is, for example, the plate (7) and the yoke (8). The permanent magnet (9) and the
center ball (io) are composed of four magnetic circuits ??. The four magnetic circuits (1) are
fixed to the back surface portion C13a of the frame Q31 having a square shape at the plate (7)
portion by screwing or the like. In the above-mentioned vibration system, the four voice coils (4)
are inserted in an annular gap ?41 circle between the plate (7) of each magnetic circuit (11) and
the center ball (101). .
The outer circumferences of the four dampers (5) are respectively bonded on the damper ring
