Description

本発明は、ヘッドホンに関し、特に音楽・音声再生装置からワイヤレスで、音楽・音声信号を飛ばしたものを受信して再生するヘッドホンに関する。   The present invention relates to headphones, and more particularly, to headphones that receive and reproduce music / audio signals skipped wirelessly from a music / audio reproduction device.

近年、携帯型音楽・音声再生装置の小型が進み、半導体メモリを使用した音楽・音声再生装置が主流となっている。   2. Description of the Related Art In recent years, portable music / sound playback devices have become smaller and music / sound playback devices using semiconductor memories have become mainstream.

また、これらの音楽・音声再生装置は、小型である特長を生かし小型のヘッドホンで再生して利用されるのが一般的である。音楽・音声再生装置とヘッドホンとは、通常コードで接続され、ヘッドホンには、音声増幅アンプ等は搭載されない。   Also, these music / sound reproduction apparatuses are generally used by reproducing with small headphones, taking advantage of their small size. The music / sound reproduction apparatus and the headphones are normally connected by a cord, and the headphones are not equipped with an audio amplifier or the like.

しかし、音楽・音声再生装置とヘッドホンとを繋ぐコードは、使用時に絡まったり、邪魔になったりとわずらわしいことが多かった。   However, the cords that connect the music / sound playback device and the headphones are often bothersome when used or get in the way.

そこで、近年では音楽・音声再生装置とヘッドホンとの信号の伝送を無線にして、電波や赤外線で行うことが実施されている（例えば特許文献１、２）。さらに、特許文献３には、太陽電池を搭載したミュージックホンが開示されている。   Therefore, in recent years, transmission of signals between a music / sound reproduction device and headphones is performed wirelessly by radio waves or infrared rays (for example, Patent Documents 1 and 2). Furthermore, Patent Document 3 discloses a music phone equipped with a solar cell.

しかし、上記従来の製品では、ヘッドホン側に信号の受信装置、信号の増幅装置、これらの装置を駆動させるための電源が必要となり、通常のヘッドホンに比較すると重量が増加する。さらに、上記従来の製品では、ヘッドホン搭載の電源が消耗すると使用不可能となり、常に電池容量を把握しながら使用する必要があった。そのために、電源に用いられる電池を大容量なものにすると重量、体積が増加するのでヘッドホンの大型化、重量化につながるのは、避けられず、快適な使用を妨げる問題があった（例えば特許文献１、２）。また、特許文献３のミュージックホンでは、太陽電池が搭載されているものの、操作部が頭部のヘッドホンにあるか有線で結ばれた操作ボックスにあるので、操作が不便であったり、わずらわしいという問題があった。   However, the above-described conventional products require a signal receiving device, a signal amplifying device, and a power source for driving these devices on the headphone side, and the weight increases as compared with ordinary headphones. Furthermore, the conventional product cannot be used when the power source mounted on the headphones is consumed, and it is necessary to always use the battery while grasping the battery capacity. For this reason, if the battery used for the power source has a large capacity, the weight and volume increase, which leads to an increase in the size and weight of the headphones. References 1, 2). In addition, although the music phone of Patent Document 3 is equipped with a solar cell, the operation unit is located in the headphone of the head or in an operation box connected by wire, so that the operation is inconvenient or troublesome. was there.

本発明は上述の点に鑑みて為されたものであり、その目的とするところは、発電機能を備え、大型の電池を搭載しなくても、また、電池の消耗を気にすることなく長時間にわたって音楽を楽しめるヘッドホンを提供することにある。
