Problems solved by technology

In addition, in the design of general earphones, the rear sound cavity is usually closed or almost closed, and then the low-frequency response of the earphone can be adjusted by adjusting the space and gas discharge of the rear sound cavity, or by setting an additional woofer to improve the sound quality.

Abstract

An earphone structure comprises a cover body, a loudspeaker, and a box body, wherein the cover body is provided with at least one first opening and at least one second opening; a loudspeaking surface of the loudspeaker is connected to the back of the cover body and surrounds the first opening; at least one partitioning wall body and at least one sound guiding wall body are arranged on the inner surface of the box body; the partitioning wall body is provided with a third opening; the cover body covers the box body; the loudspeaker is connected to the partitioning wall body; a rear sound cavity is formed by the back of the loudspeaker, the partitioning wall body and the box body; a sound guiding channel is arranged between the third opening and the second opening and outside the partitioning wall body; the sound guiding wall body is located between the third opening and the second opening; and the rear sound cavity is communicated with the second opening through the third opening and the sound guiding channel. Therefore, the earphone structure provided by the invention achieves the purpose of higher low frequencies without excessive increases to the earphone size and the earphone cost.

Description

technical field [0001] The invention relates to an earphone structure, in particular to a device capable of improving low frequency without excessively increasing the volume and cost of the earphone. Background technique [0002] When the speaker of the earphone is activated, the speaker will generate sound waves at the front and rear simultaneously, the sound waves in the front will form the front sound field, and the sound waves in the rear will form the rear sound field. Because the phases of the front and rear sound waves are just opposite, general earphones will isolate the front and rear sound waves to avoid the occurrence of front and rear sound waves canceling each other and causing the overall volume and low frequency of the earphone to drop. In the general field of earphone technology, the common way is to set the rear sound cavity, so that the sound waves of the rear sound field (hereinafter referred to as "rear sound waves") are completely or partially enclosed i...
