FIELD OF THE INVENTION The present invention relates to a loudspeaker apparatus in which a
network can be configured with a small number of parts and man-hours by f :) using a multidrive type loudspeaker apparatus. 2. Description of the Related Art Configuration of the
Conventional Example and Problems Thereof In recent years, there has been much demand for
multi-drive speaker devices, and networks have come to be used. A conventional speaker device
will be described below. FIG. 1 is a perspective view of the conventional speaker device 1, and
FIG. 2 shows a mounting part attached to the back surface of the baffle 2. FIG. 3 is a circuit
diagram of FIG. A terminal 7a for connecting the input signal to the woofer unit 3 for lowmidrange reproduction and the terminal board 5 having the terminals ea and sb for connecting
the input signal. When attaching the tweeter unit 4 for high-range reproduction having 7b and
connecting the two speaker units with the capacitor 11, the relay terminal plate 10 with the
capacitor 11 attached thereto is attached to the baffle 2 with the mounting screw 126. It
attached to the back and wired to tweeter unit terminal 7b and woofer unit terminal 6b by IJdeed 9b and 9c for internal wiring, respectively, and wired to each A line γ 6a and 7a by
internal wiring lead 9a. However, in the above-described conventional configuration, since the
relay W '::: slave plate 10, mounting screw 12 and internal wiring lead 9C are required, the
number of parts is large and the number of steps taken is long. It had the problem of. SUMMARY
OF THE INVENTION An object of the present invention is to solve the above-mentioned
conventional problems, and it is an object of the present invention to provide a speaker device
which can have the same function as the conventional one with a small number of parts and a
small number of mounting steps. Configuration of the Invention The present invention is a
speaker device provided with a spare terminal to which a network is to be connected on a
terminal plate of the speaker unit, and can have the same function as the conventional one with a
small number of parts and a small number of mounting steps. is there. Description of the

embodiment Fig. 4 shows the mounting state of the attachment part of the speaker device in one
embodiment of the present invention. In FIG. 4, 2 is a buckle plate, 3 is a woofer unit, 4 is a
tweeter unit, 5 is a terminal plate of the woofer unit, 6a and 6b are terminals attached to the
terminal plate of the woofer unit, and 6C is a spare for the capacitor 11. Terminal ,? a, 7b are
terminals of the tweeter unit, 8 is a speaker cord for input signal wiring, 9a. 9b is a lead for
internal wiring, 11 is a capacitor. The wiring method of the speaker / stem of this embodiment
configured as described above will be described below.
First, connect the input signal wiring lead 8 to the woofer unit terminals 6a and 6b, and connect
the capacitor 11 to the terminal 6b and the spare terminal 6cfζ 1, and the 11ui terminal 6C and
the tweeter terminal 7b as the internal wiring lead 9b. Further, the woofer terminal 6a and the
tweeter terminal 7a are respectively wired by the internal wiring lead 9a. As described above,
according to the present embodiment, the provision of the spare terminal 6C in the Z1.1
temporary for the ・ · · · · · makes it possible to configure a network having the same function as
the conventional one with a small number of parts and a small number of mounting steps. I can
do things. Although this embodiment has been described with two ways, it may be used for a
three-way passive speaker. The effect of the invention can be achieved, and further, by being able
to prepare the network installation work in advance, the workability can be improved, the
production cost can be reduced, and a speaker device capable of obtaining many excellent effects
can be realized. It is a thing.
