Loudspeaker assembly, loudspeaker box and mobile terminal

Abstract

The invention discloses a loudspeaker assembly, a loudspeaker box and a mobile terminal. The loudspeaker assembly includes a loudspeaker unit, an assistant loudspeaker unit, and a sound chamber unit, wherein the loudspeaker unit and the assistant loudspeaker unit share a rear chamber provided by the sound chamber unit. The low-frequency loudness of the sound played by the loudspeaker unit is enhanced by the simultaneous reverse-direction vibration of the diaphragm of the loudspeaker unit and the diaphragm of the assistant loudspeaker unit. The low-frequency loudness of the sound played by the loudspeaker unit is reduced by the simultaneous same-direction vibration of the diaphragm of the loudspeaker unit and the diaphragm of the assistant loudspeaker unit. Compared with the prior art, the loudspeaker assembly increases the low-frequency loudness of the audio output by the loudspeaker, and can greatly reduce the low-frequency loudness in a specific application scene so as to be suitable for high-frequency output. The loudspeaker assembly is particularly suitable for highly integrated or smaller and smaller mobile terminals, which helps to reduce the volume of the mobile terminal while enhancing the audio quality.

Description

technical field [0001] The invention relates to the field of mobile terminal control, in particular to a loudspeaker assembly, a sound box and a mobile terminal. Background technique [0002] As people have higher and higher requirements for the portability, ultra-thin and ultra-light of mobile terminals, the thickness of mobile terminals is getting thinner and more functions, which virtually squeezes the audio space of mobile terminals, resulting in mobile The loudspeaker of the terminal has low sound and poor reproduction effect on low-frequency sound, so the poor audio playback effect of the mobile terminal has become a pain point in use. [0003] Existing mobile terminal speaker components such as Figure 3-4 As shown, it includes a speaker unit and a sound cavity body unit, wherein the speaker unit includes a diaphragm 1, a coil 2, a magnetic steel 3 and a magnetic frame 4, and the sound cavity body unit and the diaphragm 1 of the speaker unit together form a sealed rea...

Problems solved by technology

[0002] As people have higher and higher requirements for the portability, ultra-thin and ultra-light of mobile terminals, the thickness of mobile terminals is getting thinner and more functions, which virtually squeezes the audio space of mobile terminals, resulting in mobile The loudspeaker of the terminal has a small sound and the effect of restoring low-frequency sound is poor, so the poor audio playback effect of the mobile terminal has become a pain point in use

[0003] Existing mobile terminal speaker components such as Figure 3-4 As shown, it includes a speaker unit and a sound cavity body unit, wherein the speaker unit includes a diaphragm 1, a coil 2, a magnetic steel 3 and a magnetic frame 4, and the sound cavity body unit and the diaphragm 1 of the speaker unit together form a sealed rear Sound cavity 5, based on the existing loudspeaker assembly, the method for improving the playing effect of the external high-frequency sound of the mobile terminal is usually by improving the function of the speaker and replacing a larger speaker; improving the external low-frequency sound of the mobile terminal. The method of playing the effect is usually to increase the cavity volume of the sound cavity cavity unit or fill the sound-absorbing cotton, and the above-mentioned method is contrary to the trend of ultra-thin and light-weight mobile terminals
