Problems solved by technology

[0003] The main purpose of the present invention is to propose a loudspeaker and its acoustic cavity housing, aiming to solve the problem that the power loss band affects the acoustic frequency response curve when the sound film of the loudspeaker vibrates in the prior art, so that the curve when it is installed in the cavity is the same as that when the loudspeaker is alone. The problem that the measured curve has dropped

Abstract

The invention discloses a loudspeaker and a sound cavity shell thereof, and belongs to the technical field of loudspeakers. The sound cavity shell comprises a first sound channel, a second sound channel and a third sound channel, wherein the two ends of the second sound channel are communicated with the first sound channel and the third sound channel respectively, thereby forming a channel of a U-shaped structure; a first sound outlet is formed in the end part opening of the first sound channel; and a second sound outlet is formed in the end part opening of the third sound channel. The loudspeaker comprises the sound cavity shell and a sound film, wherein the sound film is arranged in the first sound channel. Through adoption of the loudspeaker and the sound cavity shell thereof, the output sound pressure levels of loudspeakers with the same power are raised, and a frequency response curve is closer to a monomer output curve.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a loudspeaker and its acoustic cavity shell. Background technique [0002] A loudspeaker is an essential structure in a mobile terminal. When the sound membrane of the speaker of the smart terminal vibrates, it vibrates back and forth, driving the air to produce sound. In the prior art, the design of the back cavity of the loudspeaker is to set a closed space or a space with leakage holes directly behind the sound membrane. This structure does not take into account the workmanship of driving the air when the sound membrane vibrates backwards, so this part The power becomes heat loss in vain, and this situation will also affect the acoustic frequency response curve, so that the curve when installed in the cavity and the curve measured when the speaker is alone are reduced. Contents of the invention [0003] The main purpose of the present invention is to propose a loudspeaker and i...
