Double-microphone earphone microphone

Abstract

The invention provides a double-microphone earphone microphone. A circuit board is installed in a cavity, two voice tubes are installed on the circuit board, respectively an omni-directivity voice tube and a uni-directivity voice tube, a control switch can control circuits of the omni-directivity voice tube and the uni-directivity voice tube, when a switch slide sheet slides upwards, the circuit of the uni-directivity voice tube is connected, the uni-directivity voice tube starts to work, and the circuit of the omni-directivity voice tube is opened; when the switch slide sheet slides downwards, the circuit of the omni-directivity voice tube is connected, the omni-directivity voice tube starts to work, and the circuit of the uni-directivity voice tube is opened; the uni-directivity voice tube is mainly utilized during singing, voice can be accurately transmitted into the uni-directivity voice tube through a sound inlet port of a cavity upper lid, tone quality efficient transmission is achieved, noise due to voice tube air injection is reduced, the problem of poor tone quality due to the voice tube air injection when a consumer sings can be solved, and the tone quality is made more euphonic. The omni-directivity voice tube is mainly utilized in daily telephone chats, the limitation that the orientation of a sound source is not fixed can be gotten rid of, and the conversation is still clear even if body motion causes swings of the voice tube.

Description

technical field [0001] The invention relates to a novel earphone microphone in the field of electronic products, more specifically, to a dual-microphone earphone microphone.
