技术领域technical field

本实用新型涉及一种音频信号转换双向传输装置,尤指一种适用于可携式电子装置的音频信号转换双向传输装置。The utility model relates to an audio signal conversion bidirectional transmission device, in particular to an audio signal conversion bidirectional transmission device suitable for portable electronic devices.

背景技术Background technique

目前在全球范围内使用最广是所谓的第二、三代手机(2G、3G),它们除了可以进行语音通信以外,还具有收发简讯、多媒体简讯等功能。在台湾,使用全球移动通讯系统(Global System for Mobile Communications,GSM)的手机最为普及,使用个人手持式电话系统(Personal Handy-phoneSystem,PHS)的手机也逐渐流行。The so-called second and third generation mobile phones (2G, 3G) are currently the most widely used in the world. In addition to voice communication, they also have functions such as sending and receiving short messages and multimedia short messages. In Taiwan, mobile phones using the Global System for Mobile Communications (GSM) are the most popular, and mobile phones using the Personal Handy-phone System (PHS) are also becoming popular.

随着人们生活水平的提高,手机所具有的外围功能越来越多元化。以音乐播放为例,目前市场上出售的手机在播放音乐时主要是通过耳机来听音乐,经由耳机的搭配达成伶听音乐的功效。然而,长期使用耳机听音乐容易使人感到听力疲劳,即便有手机带有喇叭,但手机喇叭一般尺寸较小,且音质较差,欣赏音乐常有其不足之处。With the improvement of people's living standards, the peripheral functions of mobile phones are becoming more and more diversified. Taking music playback as an example, mobile phones currently on the market mainly listen to music through earphones when playing music, and the effect of listening to music is achieved through the matching of earphones. However, long-term use of earphones to listen to music can easily make people feel hearing fatigue. Even if there is a mobile phone with a speaker, the speaker of the mobile phone is generally small in size and poor in sound quality. Appreciating music often has its shortcomings.

此外,若使用者于开车时接听电话,或者使用耳机听音乐,很容易导致开车时精力不集中,导致对突发事件的反应能力变慢,甚至会导致意外发生。使用者虽可自行购买蓝牙耳机,但是这些产品价格较高,一般的使用者配对操作不易。因此,针对手机的播放、免持装置进行一全新的设计,便有其必要性。In addition, if the user answers the phone or listens to music with earphones while driving, it is easy to lose concentration while driving, slow down the ability to respond to emergencies, and even cause accidents. Although users can purchase Bluetooth headsets by themselves, these products are relatively expensive, and the pairing operation is not easy for ordinary users. Therefore, it is necessary to carry out a brand-new design for the playback and hands-free devices of mobile phones.
