Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a composite type speaker intended for use in a vehicle to obtain good sound quality.

Conventional configuration and its problems A conventional composite speaker of this type was configured as shown in FIG. That is, the tweeter 2 is attached to the buff-full plate 1 in which the gasket 1a and the bridge part 1b are integrally molded with resin, and this is attached to the woofer frame 3 using the speaker mounting hole 6 using the eyelet 4 and washer 5, and the buff-full plate 1 is attached. It was connected to the periphery of the woofer frame 3. In addition,
7 in the figure is a magnetic circuit for the woofer.

In this case, eyelets 4 and washers 5 are required depending on the number of eyelets, and the construction method requires the effort of inserting eyelets 4 and attaching washers 5. moreover,
Since the eyelet 4 is used, even if the speaker mounting hole 6 of the woofer frame 3 is made into an elongated hole, it will end up being a round hole with the inner diameter of the eyelet 4, which will limit the range of fit for the mounting pitch of the composite speaker. I had a problem.

Purpose of the invention This invention eliminates these conventional drawbacks, reduces the number of parts, reduces man-hours, reduces costs, and also improves installation by changing the shape of the mounting hole to the original shape of the frame. The purpose is to improve.

Structure of the invention In order to achieve this objective, the present invention provides a plurality of recesses on the outer periphery of a buttful plate in which the gasket and the bridge are integrally molded from resin, and the woofer to which this buttful plate is attached has a recess on the outer periphery of the frame. A cut-and-raised part is provided at a position that fits the concave portion of the buff-full plate, and the cut-and-raised part of the outer peripheral part of the frame embraces the buff-full plate in the inner diameter direction of the speaker, and is held by bending it.

This configuration eliminates the need for eyelets and washers, and also reduces the number of man-hours required for their installation. Additionally, the process can be done at all locations at the same time, reducing man-hours. The speaker mounting hole is not used as a frame, so it becomes the frame mounting hole itself.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

8 is a gasket part 9 for the woofer and a tweeter 10
It is a baffle plate in which a bridge portion 11 supporting the baffle plate 8 is integrally molded from resin, and four recesses 12 are provided on the outer circumference of the buffle plate 8. Further, on the outer periphery of the woofer frame 13 to which the buff-full plate 8 is attached, a cut-out 14 is provided at a position that matches the recess 12 of the buff-full plate 8. This cut and raised portion 14 is bent in the direction of the inner diameter of the speaker, and the buttful plate 8 is held and connected. In the figure, 15 is a magnetic circuit of the woofer, and 16 is a diaphragm of the woofer.

With such a configuration, the baffle plate 8 can be held with sufficient strength without using fixing parts such as washers and eyelets.

Effects of the invention As described above, by configuring a composite speaker according to the invention, there is no need for parts for fixing the buttful plate, and therefore no work is required to attach these parts, resulting in a significant cost reduction. .
In addition, since the mounting hole of the woofer is not used for holding the baffle plate, it can be directly used as the mounting hole of this composite speaker, and the range of fitting pitches can be widened.
