Embodiment Construction

[0037] The present application discloses an audio device with a sound transmission function. The audio device has a suppressing effect on sound waves emitted by near-field sound sources within a specified range, and has an effect on sound waves emitted by far-field sound sources other than the specified near-field sound source. There is a zoom effect.

[0038] The following description provides specific application scenarios and requirements of the application, with the purpose of enabling those skilled in the art to manufacture and use the contents of the application. The operation and function of these and other features of the present disclosure, as well as related elements of the structure, and the economics of assembly and manufacture of the components, may be significantly improved upon consideration of the following description. Reference is made to the accompanying drawings, all of which form a part of this disclosure. It should be clearly understood, however, that th...

Abstract

The invention provides sound equipment. The sound equipment has a suppression effect on sound waves emitted by a near-field sound source within a specified range, and has an amplification effect on sound waves from a far-field sound source outside the specified range. The sound equipment comprises a first sound wave sensor which receives sound waves and outputs a first signal based on the sound waves; a second acoustic wave sensor which receives the acoustic wave and outputs a second signal based on the acoustic wave; and a signal processing circuit which is connected with the first acoustic wave sensor and the second acoustic wave sensor and generates an output signal based on the first signal and the second signal, wherein the near-field sensitivity of the sound equipment to the sound wave is significantly lower than the far-field sensitivity to the sound wave.

Description

technical field [0001] The invention relates to the field of sound collection equipment, in particular to an audio equipment with sound transmission function. Background technique [0002] For some audio equipment with sound transmission function, such as microphone modules, in different application scenarios, the sound transmission effect requirements for near-field sound sources and far-field sound sources are different. For example, when making a phone call, people usually want to amplify the human voice closer to the mobile phone, while weakening the sound of the surrounding environment, so that the other party on the call can better hear the voice of the mobile phone user. On the contrary, in some application scenarios, people hope that the sensitivity of audio equipment to near-field sound sources will be weakened, while the sensitivity to far-field sound sources will be enhanced. [0003] For example, in the field of hearing aids, people's functional requirements for...
