Reference numeral 2 denotes a frame coupled to the field unit 1, reference numeral 3 denotes a voice coil,
4 is a damper and 5 is a diaphragm.

Reference numeral 6 denotes a tweeter.
The tweeter section 6 has a tweeter 6a connected to the upper surface of the mounting device 6b, and is led out to the bass speaker by a tinsel wire 9.

Further, a dustproof cushion 7 is connected to the center of the tweeter 6, and a mounting tool 6b provided with an insert bolt is inserted into a recess provided above the center pole of the lower plate 1c. Were combined.

[0007]

However, in the above-mentioned composite speaker, it is necessary to assemble the tweeter 6a as a fully-operated product, connect the mounting device 6b, and then assemble with the bass speaker as the main speaker. High score and low productivity. There was a problem that.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a high-sound quality composite speaker excellent in productivity by reducing the number of parts.

[0009]

In order to solve the above-mentioned problems, a composite speaker according to the present invention comprises a field part having at least a magnetic gap, a frame coupled to the field part,
A main speaker comprising a diaphragm having a voice coil fitted into the magnetic gap coupled to a central portion and an outer edge coupled to the frame; and a frame portion lower to an upper portion coupled to an upper central portion of the field portion. The tweeter frame has a mounting portion integrally formed by resin molding and a terminal insert-molded in the tweeter frame, and can provide a composite speaker excellent in productivity with a reduced number of parts. is there.

[0010]

According to a first aspect of the present invention, there is provided a magnetic head having at least a field portion provided with a magnetic gap, a frame connected to the field portion, and a voice coil fitted into the magnetic gap. A main speaker composed of a diaphragm joined to the frame and an outer edge joined to the frame, and an upper part joined to the center upper part of the field part, a frame part at the bottom and a mounting part formed integrally by resin molding A tweeter frame and a terminal insert-molded in the tweeter frame. The tweeter frame is integrated with the mounting device and the terminal to provide a composite speaker excellent in productivity with a reduced number of parts. It is.

According to a second aspect of the present invention, a choke coil for a network is disposed in the tweeter frame of the first aspect, and a part of a terminal insert-molded in the tweeter frame is connected to the choke coil for a network. The network choke coil is extended to the vicinity and the terminal is electrically connected, and the tweeter, the low-frequency speaker and the network choke coil are internally connected to each other to achieve high sound quality. is there.

An embodiment of the composite speaker according to the present invention will be described below with reference to FIGS. In the description, the same parts as in the related art will be denoted by the same reference numerals, and description will be omitted.

(Embodiment 1) FIG. 1 is a sectional view of a composite speaker according to an embodiment of the present invention. The difference from the prior art is that a tweeter frame 11 is provided. That is,
The tweeter frame 11 is formed by integrating a frame portion 11f of the tweeter and a mounting portion 11g with a high-polymer resin product. The tweeter frame 11 is formed by connecting a tinsel wire 9 to a terminal 11a insert-molded in the tweeter frame 11.
Is connected to the tweeter 11b formed in FIG.

The composite loudspeaker configured as described above can reduce the number of components as compared with the conventional loudspeaker, and can improve the productivity by reducing the number of components.

(Embodiment 2) FIG. 2 is a cross-sectional view of another embodiment of the present invention. Referring to FIG. 2, reference numeral 12 denotes a lower portion of a tweeter field portion 11c connected to the inside of a tweeter frame. A choke coil for a network which is arranged before coupling and is electrically connected to an extension 11d of the terminal 11a. The terminal 1d for the main speaker and the terminal 11a for the tweeter are connected by a tinsel wire 9 to provide a tweeter voice coil. 1
1e, the bass speaker A as the main speaker and the choke coil 12 for the network can be connected by wiring, so that the wiring is stable and the sound quality is stable, and the wiring work is easy. It becomes.

[0016]

According to the composite speaker of the present invention, at least a field portion provided with a magnetic gap, a frame connected to the field portion, and a voice coil fitted into the magnetic gap are connected to a center portion and an outer edge portion is formed. A tweeter frame comprising a main speaker composed of a diaphragm coupled to the frame, a tweeter frame integrally formed by resin molding with an upper portion coupled to an upper portion of the field portion, a frame portion at a lower portion, and a mounting portion at a lower portion; It is composed of terminals molded into a frame and can provide a composite speaker excellent in productivity by reducing the number of parts.
