【考案の詳細な説明】
この考案は、特に低域信号によって駆動される電気−機
械振動変換器に関するものである。DETAILED DESCRIPTION OF THE INVENTION The invention relates specifically to an electro-mechanical vibration transducer driven by a low frequency signal.
音楽は耳だけで聞くのではなく、全身で聞くことによっ
て臨場感が得られるものであシ、特に低周波の音は耳で
聞くのではなく全身で感じるものである。Music is not only heard with the ears, but a sense of reality can be obtained by listening to it with the whole body.In particular, low-frequency sounds are not heard with the ears, but are felt with the whole body.
そこで近年、音楽を臨場感を増して聞くものとして第１
図に示すような構造のものが開発されている。Therefore, in recent years, it has become the number one way to listen to music with an increased sense of reality.
A device with the structure shown in the figure has been developed.
以下第１図の構造のものについて説明するに、Ａは低域

性体Ｃの外周面を被覆する布製等の力・〈−である。The structure shown in Fig. 1 will be explained below.A is an electro-mechanical vibration converter (hereinafter referred to as a car converter) into which a low frequency signal is input, and B is a recess B1 in which the converter A is housed and fixed.
A vibrating body made of relatively hard resin such as hard polyethylene foam having The force of the covering cloth etc. is 〈-.
このような構造のクッションを聴取者が身体の所望個所
に弾性体Ｃ側を当てると変換器Ａの振動が、弾性体Ｃを
介して身体に伝達されるので、通常のスピーカよりの耳
で聞く音楽と、身体で感じる低音域の振動とによって、
より大なる臨場感が得られるものである。When a listener places the elastic body C side of a cushion with such a structure on a desired part of the body, the vibrations of the transducer A are transmitted to the body via the elastic body C, so that the listener can hear it with his or her ears rather than a normal speaker. Through music and the low-frequency vibrations that you feel in your body,
This provides a greater sense of reality.
ところで上記したクッションに使用される変換器Ａは第
２図に示すように構造のものが一般的である。By the way, the converter A used in the above-mentioned cushion generally has a structure as shown in FIG.
以下この図に基いて、その構造を説明する。１はヨーク

属製のカバーである。The structure will be explained below based on this figure. 1 is a magnetic circuit composed of a yoke 1as, a magnet 1b and a plate 1c; 2 is a damper made of synthetic resin whose inner periphery is fixed to the magnetic circuit 1; and 3 is a damper whose outer periphery is fixed to a step 3a. The outer peripheral edge of the metal case 4 is fixed to the stepped portion 3a of the case 30 via the damper 2,
A metal holder plate has a voice coil bobbin 5 fixed to its inner peripheral edge, 6 is a voice coil wound around the voice coil bobbin 5, and 1 is a metal cover fitted to the opening edge of the case 3.
ところで上記構造の変換器Ａにあっては、ダンパー２が
振動によって機械的に破壊しないように、破壊する振幅
が行われる以前に磁気回路１をケース３とホルダープレ
ート４に当接するように寸法設計が行われている。By the way, in the transducer A having the above structure, in order to prevent the damper 2 from being mechanically destroyed by vibration, the dimensions are designed so that the magnetic circuit 1 comes into contact with the case 3 and the holder plate 4 before the vibration that causes the damage occurs. is being carried out.
しかし変換器Ａには耳に聞こえ難い低域の周波数信号が
印加されているため、磁気回路１は大振幅で振動し、ケ
ース３釦よびホルダープレート４に当接することが多く
、ために異常音が発生し商品価値を下げ、かつ不快感を
与えるという欠点がある。However, since a low-frequency signal that is hard to hear is applied to the transducer A, the magnetic circuit 1 vibrates with a large amplitude and often comes into contact with the case 3 button and holder plate 4, resulting in abnormal noise. This has the drawback of lowering the product value and causing discomfort.
そこでダンパー２が破壊しないように、かつケース３、
ホルダープレート４に当接しないように、該ダンパー２
を強化すると、変換器Ａのｆｏが上り振幅が小さくなり
、十分なる臨場感が得られなくなると共に商品価値も低
下してしまうという欠点が生じる。Therefore, in order to prevent damper 2 from being destroyed, and case 3,
the damper 2 so as not to come into contact with the holder plate 4.
If this is strengthened, the rising amplitude of fo of the converter A will become smaller, resulting in a drawback that a sufficient sense of presence will not be obtained and the commercial value will also decrease.
この考案は斜上の点に鑑みて成されたもので、その目的
とするところは、磁気回路と、これに対応スるケース、
ホルダープレートの少なくとも倒れかに緩衝材を取付け
、磁気回路がこれらに当接しても異常音の発生を低くシ
、これによυ大振幅による臨場感が得られると共に商品
価値を高めることができる電気−機械振動変換器を提供
するにある。This idea was made in view of the diagonal problem, and its purpose was to create a magnetic circuit, a corresponding case,
A shock absorbing material is attached to at least the falling of the holder plate to reduce the generation of abnormal noise even if the magnetic circuit comes into contact with them. - To provide a mechanical vibration transducer.
次にこの考案の一実施例を第３図と共に説明する。Next, an embodiment of this invention will be described with reference to FIG.
なお第３図中、第２図と同一符号のものは同一部材を示
し、説明を省略する。Note that in FIG. 3, the same reference numerals as in FIG. 2 indicate the same members, and the description thereof will be omitted.
８はケース３の底部内周面に貼着されたスポンジ、不織
布等の緩衝材、９はホルダープレート４の下面に貼着さ
れたスポンジ、不織布等の緩衝材である。Reference numeral 8 denotes a cushioning material such as a sponge or nonwoven fabric that is attached to the inner peripheral surface of the bottom of the case 3, and 9 is a cushioning material such as a sponge or nonwoven fabric that is attached to the lower surface of the holder plate 4.
この考案にあっては、ケース３とホルダープレート４の
夫々内面に緩衝材８，９を貼着したので、大入力信号に
よって磁気回路１が大振幅してケース３、ホルダープレ
ート４に当接しても緩衝材８゜９に当接するので、殆ど
異常音の発生がなく、また振動体Ｂ１弾性体Ｃを介して
変換器Ａに機械的な衝撃が加わっても異常音の発生は阻
止され、しかもダンパー２は破壊されない振幅で制限さ
れるノテ、ダンパー２の破壊も防止できる。In this invention, since the cushioning materials 8 and 9 are attached to the inner surfaces of the case 3 and the holder plate 4, respectively, a large input signal causes the magnetic circuit 1 to have a large amplitude and come into contact with the case 3 and the holder plate 4. Since the transducer A comes into contact with the buffer material 8°9, almost no abnormal noise is generated, and even if a mechanical shock is applied to the transducer A through the vibrating body B1 and the elastic body C, the generation of abnormal noise is prevented. Note that the damper 2 is limited by the amplitude at which it cannot be destroyed, and damage to the damper 2 can also be prevented.
なお上記した実施例はケース３とホルダープレート４の
磁気回路１との対向面に緩衝材８，９を貼着したものを
示したが、緩衝材８，９は磁気回路１のケース３とホル
ダープレート９との対向面に貼着しても良いことは勿論
のことである。In addition, in the embodiment described above, the cushioning materials 8 and 9 were attached to the surfaces of the case 3 and the holder plate 4 facing the magnetic circuit 1, but the cushioning materials 8 and 9 were attached to the case 3 of the magnetic circuit 1 and the holder. Of course, it may be attached to the surface facing the plate 9.
この考案は上記したように、磁気回路、これに対向する
ケース、ホルダーグレートの少なくとも何れかの対向面
に緩衝材を貼着したことにより、磁気回路が大きく振動
しても衝撃音の発生が少なく、かつ外部からの機械的な
衝撃によっても異常音が発生し難い外、ダンパーの振幅
も制限されるので破壊の危険性も少ない等の効果を有す
るものである。As mentioned above, this idea is based on the fact that a cushioning material is attached to at least one of the facing surfaces of the magnetic circuit, the case facing it, and the holder grate, thereby reducing impact noise even when the magnetic circuit vibrates strongly. Moreover, it has the advantage that not only is it difficult to generate abnormal noise even when mechanical shock is applied from the outside, but also that there is less risk of damage because the amplitude of the damper is limited.
