BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
composite speaker used as a vehicle. Conventional Technology A conventional speaker of this
type has a structure as shown in FIG. That is, the inner peripheral edge portion of the dustproof
damper (2) was bonded to the upper end sticking portion (1a) of the supporter (1). In FIG. 3, (3)
is a tweeter, (4) is a magnet, and (5) is a bottom plate. (6)はウーハである。 Problems to be
Solved by the Invention However, with the above-mentioned conventional structure, the height h
of the upper end sticking portion (1a) of the supporter (1) is required, which is disadvantageous
when a thin speaker is required. また。 When the outer diameter of the magnet (4) and the
bottom plate (5) of the tweeter (3) is large, there is a problem that the dustproof damper (2) hits
the tweeter (3) at the time of large amplitude. An object of the present invention is to provide a
composite speaker in which the above problems are eliminated. Means for Solving the Problem
In order to solve the above problem, the present invention ρ composite type speaker comprises
a woofer, a tweeter coaxially disposed on the front side of the woofer, and a dustproof damper
for dustproofing to the woofer gap The dustproof damper has an inner peripheral edge bonded
to a sticking step formed on an outer periphery of a lower end of the bottom plate of the tweeter.
Operation With the above configuration, the dustproof damper-adhesion portion of the
conventional supporter becomes unnecessary, the tweeter can be lowered by the thickness, and a
thin speaker can be obtained. In addition, since the dustproof damper is adhered near the outer
shoulder of the field section of the tweeter, the dustproof damper does not hit the tweeter during
large amplitude. Embodiment Hereinafter, one embodiment of the present invention will be
described with reference to FIGS. 1 and 2. FIG. FIG. 1 is an enlarged cross-sectional view of the
vicinity of the dustproof damper attachment portion of the composite speaker in one
embodiment of the present invention, FIG. 2 is a cross sectional view of the left half of the
composite speaker, and (7) is a tweeter, (8) Woofer, (9) Woofer (8) bottom plate, (10) supporter,

(11) dustproof damper, (12) Woofer (8) cone, (13) tweeter (7) The bottom plate of (14) is a
magnet, and (13a) is a sticking step. The tweeter (7) is supported by a supporter (10) on the
bottom plate (9) of the woofer (8). The outer peripheral edge of the dustproof damper (11) for
dustproofing into the gap of the woofer (8) is bonded to the cone (12) of the woofer (8).
The inner peripheral edge portion of the dustproof damper (11) is bonded to a sticking step
portion (13a) provided on the outer periphery of the upper end portion of the bottom plate (13)
of the tweeter (7). Hereinafter, the operation in the above configuration will be described.
According to the above configuration, the dustproof damper attaching portion of the supporter
(10) is attached by attaching the inner peripheral edge portion of the dustproof damper (11) to
the sticking portion (13a) of the bottom plate (13) of the tweeter (7). It is possible to make it a
composite type speaker with a low overall height. Also, the dustproof damper (11) does not hit
the tweeter (7) even when the amplitude is large. Effect of the Invention As described above,
according to the present invention, by sticking the inner peripheral edge portion of the dustproof
damper to the tweeter, the dustproof damper attached portion of the supporter can be
eliminated, and a composite speaker with a low overall height can be obtained. Also, even with a
large magnet tweeter, the dustproof damper does not hit the tweeter when the amplitude is large.
