本发明属于降噪装置技术领域，具体涉及一种能主动式降噪耳机音质提升的装置。The invention belongs to the technical field of noise reduction devices, and in particular relates to a device capable of improving the sound quality of active noise reduction earphones.
背景技术Background technique
众所周知，主动式降噪的频率段是体现在低频段，一般是指50—600HZ这一频率段，而在这一频率段要做到降噪效果好，必须要将喇叭及整个耳机对应的低频段灵敏度提高，同时也要压制1KHZ以上的中高频灵敏度，否则降噪效果难以做到最佳。而喇叭及整个耳机对应的低频段灵敏度提升，中高频被压低后的结果是收听的音乐音质效果就受到影响，听起来低频很沉重很闷，听时间稍长点，人会感觉很疲惫。另外，这种同一个喇叭输出的工作方式，也对人的通话语音有不利的影响，即当开启降噪效果时，周边的环境杂音降低了，但同时也把跟你在旁边通话的人的语音也给降低了，这样导致的结果是使得双方通话不够顺畅。而即使是有些耳机品牌公司想通过电子电路去弥补，那也是有限的，更何况付出的是材料成本的增加，时间成本的增多，生产效率的低下，还有整个电路的耗电等不良因素产生，是得不偿失的一种方法。为此提出一种能主动式降噪耳机音质提升的装置。As we all know, the frequency range of active noise reduction is reflected in the low frequency range, which generally refers to the frequency range of 50-600HZ. In order to achieve a good noise reduction effect in this frequency range, the corresponding low frequency of the speaker and the entire earphone must be adjusted. The sensitivity of the frequency band is improved, and at the same time, the sensitivity of the medium and high frequencies above 1KHZ must be suppressed, otherwise the noise reduction effect will not be optimal. The sensitivity of the low-frequency band corresponding to the speaker and the entire earphone is improved, and the result of lowering the mid-high frequency is that the sound quality of the music listened to is affected. In addition, this working method of the same speaker output also has a negative impact on the voice of the person talking, that is, when the noise reduction effect is turned on, the surrounding environmental noise is reduced, but at the same time it also reduces the voice of the person talking next to you. The voice is also reduced, which results in the communication between the two parties not being smooth enough. And even if some earphone brand companies want to make up for it through electronic circuits, that is limited, not to mention the increase in material costs, time costs, low production efficiency, and the power consumption of the entire circuit. , is a method that outweighs the gain. To this end, a device capable of improving the sound quality of active noise reduction earphones is proposed.
