Double-sided ultrathin loudspeaker

Abstract

The invention relates to the technical field of electro-acoustic conversion, in particular to a double-sided ultrathin loudspeaker, which is characterized in that a first loudspeaker individual and asecond loudspeaker individual are arranged in a cavity of a basin frame; the first loudspeaker individual is arranged on the upper end surface of the basin frame; and the second loudspeaker individualis arranged on the lower end surface of the basin frame. When the low-frequency effect needs to be enhanced, a second vibration system is not powered on while the normal sounding first vibration system is powered on to work, and a voice diaphragm part is used as a back plate for enhancing the bass part; the voice coils of the first vibration system and the second vibration system are electrified,when the two voice diaphragm parts vibrate, a good damping effect is achieved, and the resonance risk of the whole machine is greatly reduced; a nine-magnet design is used, the loudspeaker is made tobe thin, a high sound effect of the loudspeaker can be achieved, first side edge magnetic steel in the first magnetic circuit system and second center magnetic steel in the second magnetic circuit system are the same part, and a magnetic bowl of the first magnetic circuit system and a second center polar plate in the second magnetic circuit system are the same part. Therefore, the size of the loudspeaker is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion, in particular to a double-sided ultra-thin loudspeaker. Background technique [0002] In recent years, as people's requirements for the sound quality of electronic products (computers, tablets, mobile phones, etc.) have improved, the speaker products used have to be optimized and changed in design. Usually low frequency is the key frequency band that affects the general consumer's sense of hearing. In order to let consumers have a high-quality listening experience, we need to strengthen the low frequency of the speaker. What needs to be considered now is the thinner and thinner design of electronic products. In this case, we must also pay attention to how to maintain or even improve the low-frequency effect when the speaker is made thin. The thinning of the whole machine will also strengthen the resonance risk of the whole machine part. Contents of the invention [0003] Th...
