Embodiment Construction

[0091] figure 1 It is a perspective view of a microphone device according to an embodiment of the present invention. Please refer to figure 1 , the microphone device 10 of this embodiment includes a first sound receiving module 100 and a second sound receiving module 200 . The first sound receiving module 100 is used for receiving a sound source signal (such as far-field noise) and outputting a first electronic signal. The second sound receiving module 200 is used for receiving the sound source signal (such as far-field audio) and outputting a second electronic signal. Wherein, the first sound receiving module 100 is coupled to the second sound receiving module 200 , and the phases of the first electronic signal and the second electronic signal are opposite to each other, so as to achieve mutual cancellation of the electronic signals generated by far-field noise.

[0092] The microphone device 10 of this embodiment further includes a sound collecting groove 300 . The first...

Abstract

A microphone device includes a first audio receiving module, a second audio receiving module and an audio collecting groove. The first audio receiving module receives an audio source signal to output a first electronic signal. The second audio receiving module receives the audio source signal to output a second electronic signal. The first audio receiving module is coupled to the second audio receiving module. The phase of the first electronic signal is opposite to that of the second electronic signal. The distance between the first audio receiving module and the audio collecting groove is smaller than the distance between the second audio receiving module and the audio collecting groove. Another audio source signal is transmitted to the first audio receiving module through the audio collecting groove.

Description

technical field [0001] The present invention relates to a microphone device, and in particular to a microphone device capable of canceling far-field noise. Background technique [0002] With the continuous advancement of technology, personal electronic products are all moving towards the trend of light weight and miniaturization. Smart phones, tablet computers or notebook computers have become indispensable in people's daily life. Regardless of the above-mentioned electronic products, in order to allow users to listen to the sound information provided by the electronic product without disturbing others, earphones have become a necessary accessory for the electronic product. In addition, in order to use electronic products to make calls, headset microphones equipped with microphones are also common accessories. [0003] In order to take into account the two functions of listening to sound and collecting sound, the traditional earphone microphone adopts a separate design of t...
