AI Technical Summary

Technical Problem

When existing headphones improve bass performance through speaker hardware optimization, the headphones become larger, making miniaturization difficult.

Method used

A sound guide channel is set on the shell of the earphone to connect the first receiving cavity with the outside world. This balances the air pressure inside the cavity when the speaker is working, reduces the resistance of diaphragm movement, increases the vibration amplitude in the low frequency range, and obtains a larger ventilation area and a longer channel length in a limited space through the sound guide channel.

Benefits of technology

Achieving deeper low-frequency extension and fuller bass effect within a smaller structural space, while maintaining the headphone's slim design.

Abstract

The earphone provided by the embodiment of the application relates to the technical field of earphones. The earphone is provided with a sound guide channel on the shell, the sound guide channel is connected with the first accommodating cavity of the shell and the outside, the air pressure in the cavity is balanced when the loudspeaker works, the movement resistance of the diaphragm of the loudspeaker is reduced, and the vibration amplitude of the loudspeaker in the low frequency band is improved. Moreover, the projection of the sound guide channel on the shell is arranged around the loudspeaker, the sound guide channel can obtain a larger ventilation area and a longer channel length in a limited space, so that deeper low frequency diving and fuller bass effect can be realized in a smaller structural space.
