Loudspeaker and headset

Abstract

The invention discloses a loudspeaker and a headset. The loudspeaker comprises a high pitch unit, a low pitch unit, passive vibrating diaphragm and a frame. The frame comprises a first frame body partand a second frame body part. The high pitch unit and the low pitch unit are stored in the first frame body part. The second frame body part is equipped with an upper frame and a plurality of side arms connected between the upper frame and the top end of the first frame body part. The plurality of side arms are spaced, so a plurality of through holes are defined among the top end of the first frame body part, the upper frame of the second frame body part and the plurality of spaced side arms. Part of sound saves produced by the high pitch unit and the low pitch unit are transmitted from the through holes. The other part of sound waves are absorbed and reflected by the passive vibrating diaphragm, thereby obtaining low frequency sound waves. The low frequency sound waves are transmitted from the through holes. The high pitch unit, the low pitch unit and the passive vibrating diaphragm are set in the frame, so a size of the loudspeaker is greatly reduced, a processing process is simplified, and the cost is reduced.

Description

technical field [0001] The invention relates to a loudspeaker and an earphone. Background technique [0002] Traditional earphones are usually driven by a single speaker unit due to limited space. The advantage is that the overall structure of the earphone can be designed to be lighter, thinner and shorter to match the design of in-ear or on-ear earphones. However, the same speaker unit usually has a good response performance in a specific frequency band, but the response performance in other frequency bands is not so ideal. Generally speaking, the frequency response in the middle and low frequency bands is usually better, while the frequency response in the high frequency band is not good. [0003] Therefore, at present, multiple speaker units with different frequency bands are used on the earphone to improve frequency band response and sound resolution. However, due to the limited overall space of the earphone, the path distances of different speaker units to the sound o...

AI Technical Summary

Problems solved by technology

However, due to the limited overall space of the earphones, the path distances from different speaker units to the sound outlet are almost the same, but the response effects of each audio to the hearing are different. For example, at the same distance, the user's perception of bass Strong, which in turn affects the resolution of the treble

In order to adjust the auditory effect, the current common way is to change the driving mode or increase the passive diaphragm. However, the existing passive diaphragm is usually set separately from the speaker unit, which will result in a larger accommodation space. That is, the size of the earphones will become larger.
