DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a speaker device,
which can be easily assembled with a small number of parts, such as a network substrate forming
a branching circuit etc. and parts such as a breaker operating at the time of excessive input
application. In general, one speaker box with multiple speakers for high, middle and low
frequencies, so-called multi-channel 121 :), yp22 quadruple way speaker system, high and
middle. It is known to use an electric circuit (nesotowar) using electronic components such as a
capacitor and a choke coil in order to touch an unnecessary band of bass and make the
frequency characteristic to be mainly crossed flat. FIG. 1 shows such a conventional speaker
device, wherein 1 is a capacitor, 2 is a choke coil, 3 is a network substrate for electrically
connecting the capacitor 1 and the choke coil 2, 4 and 6 are networks. Screws and nuts for fixing
the choke coil 2 to the substrate 3, 6 are lead wires fixed to the network substrate, 7 is a speaker
box molded of resin, 8 is for attaching the neon substrate 3 to the outer case 1 The screw 11 is a
faston terminal connected to the end of the lead wire 6. By the way, in recent years, in order to
prevent the speaker unit from being broken due to excessive input, a breaker has come to be
used. The breaker 9 shown in FIG. 1 is inserted between the input terminal 1o and the network
board 3, and when a current exceeding the specified value flows, the electric circuit is opened
like the machine 112.23 and no excessive input is applied. I have to. The breaker 9 is attached
between the breaker fitting 12 and the speaker box 7 by the nis 8. Then, after the breaker 9

operates, it is necessary to mechanically turn on the electric circuit, so the knob 9a must be taken
out of the speaker box 7. For this reason, the mounting of the breaker 9 is usually performed
separately from the mounting of the network substrate 3. Therefore, in this case, since the
network substrate 3 and the breaker 9 have to be attached separately, the number of parts
increases and the number of assembling steps also increases. SUMMARY OF THE INVENTION
The present invention provides a sliding-force device which overcomes the above-mentioned
disadvantages of the prior art. An embodiment of the present invention will be described below
with reference to FIG. 2.) 379 shown in FIG. 2 are a network board, a speed box and a breaker
similar to those shown in FIG. And 7a and 7b1234-are the post with groove 7C and the lip with 4
part 7d which were simultaneously molded with the speaker box 7, respectively.
In the above configuration, the breaker 9 is inserted between the recess 7 d and the end of the
network substrate 3 by inserting the breaker 9 into the recess 7 d of the lip 7 b of the speaker
box 7 and inserting both ends of the network substrate 3 into the groove 7 c of the support 7 a.
And the network substrate 3 is also fixed between the grooves 7c and Tc. For this reason, the
installation of the network substrate 3 and the breaker 9 is completed at one time, moreover, the
breaker fitting 12 and the screw 8 in FIG. 1 become unnecessary, and the work of attaching them
becomes unnecessary. In addition, as shown in FIG. 2, if the notch 3a is provided at the end of
the substrate 3 for a notch and the notch 3a is fitted to the breaker 9, the breaker 9 can be held
more stably. . Further, although the groove 7c and the recess 7d are supported in the
embodiment)-provided in the pillar 7a and the lip 7b, they may be provided directly on the inner
wall surface of the speaker box 7. Moreover, it can not be said that it can be applied to
attachment of parts other than a breaker, as it is said. As described above, according to the
present invention, a pair of grooves and four parts are provided on the inner surface of the
speaker box, and parts such as breakers are accommodated in the recess and both ends of the
network substrate are inserted into the pair of grooves. Since the parts such as the breaker are
held between the recessed portions, the network board and the breaker can be easily attached
with a small number of parts.
