Abstract

The invention discloses an earphone which comprises a shell, a loudspeaker and a microphone. The loudspeaker and the microphone are installed in the shell, and a sound outlet hole is formed in the shell and located at the front end of the loudspeaker; the shell forms a pickup tube which is isolated from the loudspeaker. The pickup pipe is provided with a sound pickup hole communicated with the outside, the microphone is arranged in the pickup pipe, the pickup pipe between the sound pickup hole and the microphone forms a squeal suppression pipeline, and the squeal suppression pipeline comprisesa main pipe and a variable cross-section pipe which is located in the middle of the main pipe and is different from the main pipe in cross-section area. By applying the earphone provided by the invention, through the arrangement of the squeal suppression pipeline, high-frequency standing waves with different frequencies generated by a small closed space cavity formed by the full-handshake palm and the earphone or the earphone and the battery compartment or the earphone and other small closed space cavities can be suppressed, and howling is eliminated.

Description

technical field [0001] The present invention relates to the technical field of audio equipment, and more particularly, to an earphone. Background technique [0002] With the development of listening aid and active noise reduction technology and earphones, people have higher requirements for the function and performance of earphones. Most earphones now have auxiliary listening or transparent transmission functions. [0003] One or more microphones are usually set on the earphone, and the microphone is connected with the speaker through the PCBA. In the transparent transmission, monitoring or listening mode, the external sound signal enters the microphone, the microphone converts the sound signal into an electrical signal, and after signal processing and amplification on the circuit board, it is output to the speaker, and the speaker sends this signal to the outside world. However, when the earphone deals with a small space, the microphone can easily collect the signal from ...
