Problems solved by technology
[0003] The existing terminal active noise reduction system must stack three microphones on the terminal to realize the active noise reduction function, and the structure and sound cavity of these three microphones need to meet certain design specifications, so it is necessary to allocate more resources to the audio Space resources, it is difficult to balance the needs of each design module, increasing the difficulty of stacking
Achieving active noise reduction also needs to add a set of microphone input channels on the basis of ordinary noise reduction systems, and logic resources need to be added in hardware design, resulting in increased design difficulty and cost

Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0032] see figure 1 and figure 2 , the embodiment of the terminal fittings of the present invention includes:
[0033] Accessory body 10;
[0034] The first microphone 20 is arranged on the accessory body 10 close to the earpiece, and is used to pick up environmental noise signals to cooperate with the earpiece to achieve noise reduction.
[0035] The terminal accessory further includes a first interface 30 disposed on the accessory body 10 and electrically coupled with the first microphone 20 .
[0036] see figure 2 , the first interface 30 includes a metal plug, and the metal plug includes a microphone signal line 301 and a ground line 302 electrically coupled with the first microphone 20 .
[0037] In this embodiment, the accessory body 10 is a protective terminal cover, and the first microphone 20 is respectively connected to the microphone...

The invention discloses a terminal accessory and a terminal assembly for realizing active noise reduction. The terminal accessory includes an accessory body and a second device which is arranged at a position close to the earpiece of the accessory body and is used to pick up environmental noise signals to cooperate with the earpiece to achieve noise reduction. a microphone. The present invention sets the ANC microphone installed on the terminal in the prior art to the terminal accessories, and multiplexes the microphone input path of the earphone interface, realizes the ANC function while not occupying the microphone stacking space and input path of the terminal, and reduces the stacking cost. It reduces the difficulty and cost of terminal design, and provides users with the space to choose the ANC function.
Description
technical field [0001] The invention relates to the field of electronic accessories, in particular to a terminal accessory and a terminal assembly for realizing active noise reduction. Background technique [0002] With the popularization of various smart electronic devices, mobile phones and other terminals have become quite important electronic devices in people's daily life. However, a noisy environment will seriously affect the call quality and audio playback of the terminal, reducing the accuracy of receiving voice information. Therefore, the demand for terminal noise reduction is also growing rapidly. [0003] The existing terminal active noise reduction system must stack three microphones on the terminal to realize the active noise reduction function, and the structure and sound cavity of these three microphones need to meet certain design specifications, so it is necessary to allocate more resources to the audio Space resources make it difficult to balance the need...
