た。 In a composite speaker in which a piezoelectric treble speaker is placed in front of the diaphragm of an electrodynamic bass speaker, the treble speaker 3 is fixed to the bass speaker as shown in FIG. Support 2 fixed to frame 1
or a support 22 fixed to the center pole 21 of the bass speaker as shown in FIG.
In most cases, this was done by fixing it to the
このような従来の固定構造において特別の支持

この考案は前記支持具を用いないで高音用スピ
ーカーを固定するための構造であつて、更には高
音用スピーカーのフレームをも省略するための構
造であり、以下詳細に説明する。 This invention is a structure for fixing a treble speaker without using the support, and is also a structure for omitting the frame of the treble speaker, and will be described in detail below.

ある。 In FIG. 3, 31 is an electrodynamic bass speaker, 31a is a magnetic circuit, and 31b is a voice coil 31c disposed in the magnetic gap of the magnetic circuit.
The coil bobbin 31d wound with the coil bobbin 31b has its top portion attached to the upper end of the coil bobbin 31b, and its outer periphery attached to the frame 3.
A truncated conical diaphragm 31f is connected to each opening edge of the diaphragm 1e, and a damper 31f supports the center of the coil bobbin 31b, which is a well-known electrodynamic speaker.

２ａは駆動源たる圧電素子であり、当該圧電素子
３２ａの中心には円錐状凹部３２ｂの頂部が固着
されている。 32 is a piezoelectric high-pitched speaker placed in front of the diaphragm 31d, as shown in FIG.
2a is a piezoelectric element serving as a driving source, and the top of a conical recess 32b is fixed to the center of the piezoelectric element 32a.

プライアンスを介しドーム状側面部３２ｃが連設
され、当該ドーム状側面部３２ｃの外周縁は低音
用スピーカー３１の振動板３１ｄに固着されてい
る。 A dome-shaped side surface portion 32c is connected to the outside of the opening of the conical recess 32b through appropriate mechanical compliance, for example by reducing the thickness, and the outer peripheral edge of the dome-shaped side surface portion 32c has a low-frequency sound. The diaphragm 31d of the speaker 31 is fixed to the diaphragm 31d.
しかして、ドーム状側面部３２ｃは円錐状凹部
３２ｂを振動部とし、圧電素子３２ａを駆動源と

る。 Thus, the dome-shaped side surface portion 32c functions as a support for the piezoelectric speaker 32, which uses the conical recess 32b as a vibrating portion and uses the piezoelectric element 32a as a driving source.
又圧電素子３２ａは、たとえば低音用スピーカ
ー３１のボイスコイル３１ｃ巻端線３１ｈと錦糸

号が入力される。 Further, the piezoelectric element 32a is electrically connected to, for example, a connecting portion between the voice coil 31c winding end wire 31h of the bass speaker 31 and the tinsel wire 31g, and an electrical signal is input thereto.
本考案のこのような構成によれば圧電型スピー
カーをその機能が達せられるように低音用スピー
カーに固定するようにしてあるので他の支持体や
圧電型スピーカーのフレームも必要としない。 According to this structure of the present invention, since the piezoelectric speaker is fixed to the bass speaker so that its function can be achieved, no other support or frame of the piezoelectric speaker is required.
更にドーム状側面部３２ｃと円錐状凹部３２ｂ
が防塵キヤツプとして作用するので従来の構成に
比較して部品点数を著しく減少せしめ、かつ組立
も容易になることから製品コストを著しく減少せ
しめることが可能となる。 Further, a dome-shaped side surface 32c and a conical recess 32b
Since it acts as a dustproof cap, the number of parts can be significantly reduced compared to the conventional structure, and assembly is also easier, making it possible to significantly reduce product cost.
又支持体となるドーム状側面部３２ｃは円錐状
凹部と一体に成形することができるので従来の支
持体と比較すると部品コストは著しく低いもので
ある。 Further, since the dome-shaped side surface portion 32c serving as the support body can be molded integrally with the conical recess, the cost of parts is significantly lower than that of conventional supports.
なお支持体はドーム状側面形状に特定されるも
のでなく、円錐側面、あるいは平板状であつても
よい。 Note that the support body is not limited to a dome-like side surface shape, and may have a conical side surface shape or a flat plate shape.
