一种双降噪入耳式耳机A double noise-canceling in-ear earphone

技术领域technical field

本发明属于耳机技术领域，具体涉及一种双降噪入耳式耳机。The invention belongs to the technical field of earphones, and in particular relates to a double-noise-reduction in-ear earphone.

背景技术Background technique

耳机带给人美的音乐享受，噪音却让人感到不适。为追求更高的音乐品质，我们需要最大限度地降低耳机噪音。要消除耳机噪音首先要弄清耳机噪音的来源。耳机噪音来源主要有三个：一是耳机外部环境的，二是耳机内部的，三是耳机受外部信号干扰自身产生的。外部环境的噪音复杂多变，耳机内部的噪音主要来自耳机发声体自身发出的声音在耳机空腔内产生的窜音，外部电磁信号也容易干扰耳机使耳机产生噪音。Headphones bring beautiful music enjoyment, but the noise makes people feel uncomfortable. In pursuit of higher music quality, we need to minimize headphone noise. To eliminate headphone noise, first find out the source of the headphone noise. There are three main sources of earphone noise: one is the external environment of the earphone, the other is internal to the earphone, and the third is the earphone itself generated by the interference of external signals. The noise of the external environment is complex and changeable. The noise inside the earphone mainly comes from the sound emitted by the earphone sounding body itself in the earphone cavity. External electromagnetic signals can also easily interfere with the earphone and cause the earphone to generate noise.

市面上的降噪耳机基本上都是采用主动式降噪技术，仅仅解决了“听”这单一方面问题，没有解决到“说”降噪的问题。另外，由于听降噪喇叭和听音乐喇叭是同一个喇叭输出，而两者要想都获得最佳的效果在原理上是互相矛盾的，或者说在电子电路上相对要花费极高成本的，不仅成本提高了，也比较耗电。因此，需要设计出一种双降噪入耳式耳机解决上述提到的问题。The noise-cancelling headphones on the market basically use active noise-cancellation technology, which only solves the single problem of "listening", but does not solve the problem of "speaking" noise-cancelling. In addition, since listening to the noise reduction speaker and listening to the music speaker is the same speaker output, it is contradictory in principle to obtain the best effect for both, or it will cost a relatively high cost on the electronic circuit. Not only the cost has increased, but also more power consumption. Therefore, need to design a kind of double noise reduction in-ear earphone to solve the above-mentioned problem.

The ANC noise reduction The microphone unit 7 is electrically connected with the earphone volume control assembly 3, and the ANC noise reduction speaker unit 8 is electrically connected with the earphone volume control assembly 3, and the ANC noise reduction speaker unit 8 is arranged on the left side of the speaker unit 9 for listening to voice or music. side, and the ANC noise reduction speaker unit 8 is electrically connected to the speaker unit 9 for listening to voice or music. The conductive vibration sensor 10 is electrically connected with the main control box 4 .

工作原理：使用时，打开主控制盒4电源开关，开启DNC双降噪功能，分三个重要组成部分：第一，实现“听”部分降噪功能，即常见的ANC降噪功能，ANC降噪麦克风单元7收集外部周围环境噪音，噪音信号通过主控制盒4主控板电路处理，形成与ANC降噪麦克风单元7收集的噪音反相位信号输出给噪音处理喇叭，最后喇叭输出的信号波就可以达到降低或抵消噪音信号的效果；第二，实现“说”部分降噪功能，当在嘈杂环境下选用骨传导震动传感器10作为通话说话时，对方基本上听不到你嘈杂环境对她的干扰；第三，实现“音”部分的功能，本发明采用独立的听取语音或音乐喇叭单元9来独立收听音乐和通话语音，不共用ANC降噪喇叭单元8,以避免音乐效果受到局限和影响。Working principle: When in use, turn on the power switch of the main control box 4 and turn on the DNC dual noise reduction function. The noise microphone unit 7 collects the external ambient noise, and the noise signal is processed by the main control board circuit of the main control box 4 to form an anti-phase signal with the noise collected by the ANC noise reduction microphone unit 7 and output to the noise processing speaker, and finally the signal wave output by the speaker The effect of reducing or canceling the noise signal can be achieved; secondly, the noise reduction function of the "speaking" part is realized. When the bone conduction vibration sensor 10 is used as a conversation in a noisy environment, the other party basically cannot hear you in the noisy environment. The third, to realize the function of "sound" part, the present invention adopts independent listening voice or music speaker unit 9 to independently listen to music and conversation voice, and does not share the ANC noise reduction speaker unit 8, so as to avoid the music effect being limited and influences.
