Abstract

The invention provides a sound production device, which comprises a bracket, and a magnetic circuit system, a first vibration system and a second vibration system which are fixedly connected to the bracket, the bracket is provided with a first opening and a second opening which face opposite directions, and the magnetic circuit system is used for driving the first vibration system and the second vibration system to produce sounds in different directions. The first vibration system comprises a first voice coil, the second vibration system comprises a second voice coil, the magnetic circuit system comprises first magnetic steel, second magnetic steel and third magnetic steel which are sequentially arranged at intervals and oppositely arranged in the second direction, and the polarity of a magnetic pole, opposite to the second magnetic steel, in the first magnetic steel is the same as that of a magnetic pole, opposite to the first magnetic steel, in the second magnetic steel. The polarityof a magnetic pole, opposite to the third magnetic steel, in the second magnetic steel is the same as the polarity of a magnetic pole, opposite to the second magnetic steel, in the third magnetic steel, the first voice coil sleeves the first magnetic steel and the second magnetic steel at the same time, and the second voice coil sleeves the second magnetic steel and the third magnetic steel at the same time. According to the invention, the loudness of the sound produced by the sound production device can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of sound generation, in particular to a sound generation device. 【Background technique】 [0002] In order to achieve a better sound effect in the prior art, the sounding device is generally designed as a double-sided sounding device, that is, a double-sided sounding device. The double-sided sounding device is equipped with a magnetic circuit system and two sets of vibration systems. The magnetic circuit system simultaneously The two sets of vibration systems are driven to make the two sets of vibration systems produce sound respectively, so as to achieve the purpose of making the sound generating device have better sound effect. However, the magnetic circuit efficiency of the magnetic circuit system of the existing sound generating device is relatively low, resulting in poor sound producing effects of the two vibration systems. [0003] Therefore, it is necessary to provide a sounding device with better s...
