振動発生器は、上記で例示したような小型のものに限られない。基本的構成を同一とする大型な振動発生器を構成してもよく、その場合であっても、上述と同様の効果を得られる。
上述の特許文献1に記載の振動発生装置において、板ばねは、細長い帯状に形成されており、振動体の両側方に1つずつが配置されている。板ばねの長手方向の一端部は、振動体の側面の一部に固着されており、他端は、ケースの周壁面に固着されている。ここで、上記のような構造を用いた振動発生装置には、次のような問題がある。すなわち、このような振動発生装置を製造するには、板ばねを振動体に取り付ける作業と、板ばねをケースに取り付ける作業とが必要になる。板ばねを振動体やケースに取り付けるには、一般的には、レーザ溶接などの固着方法を用いることが必要であるが、例えばレーザ溶接でこのような作業を行うと、振動発生装置の製造コストが高くなる。特に、例えば携帯端末等の民生品に使用される部品については、製造コストの低減が強く要求されているところ、上記のような構造を採用すると、このような要求に応えることができなくなることがある。このような問題に関して、特許文献2から4のいずれにも、有効な解決策は開示されていない。上記実施の形態では、製造コストを低減可能な振動発生器を提供できる。
The vibration generator is not limited to a small one as exemplified above. Large vibration generators having the same basic configuration may be configured, and even in this case, the same effects as described above can be obtained.
In the vibration generating device described in Patent Document 1 described above, the leaf springs are formed in an elongated strip shape, and one is arranged on each side of the vibrating body. One end of the leaf spring in the longitudinal direction is fixed to a part of the side surface of the vibrating body, and the other end is fixed to the peripheral wall surface of the case. Here, the vibration generator using the above structure has the following problems. That is, in order to manufacture such a vibration generator, an operation of attaching the leaf spring to the vibrating body and an operation of attaching the leaf spring to the case are required. In order to attach the leaf spring to the vibrating body or the case, it is generally necessary to use a fixing method such as laser welding. However, if such work is performed by laser welding, for example, the manufacturing cost of the vibration generator is reduced. Becomes higher. In particular, for parts used in consumer products such as mobile terminals, there is a strong demand for reduction in manufacturing costs. However, if such a structure is adopted, it may not be possible to meet such demands. is there. Regarding such a problem, none of Patent Documents 2 to 4 discloses an effective solution. In the said embodiment, the vibration generator which can reduce manufacturing cost can be provided.
