Document Type and Number:
WIPO Patent Application WO/2022/062034
Kind Code:
A1
Abstract:
Provided are a loudspeaker and an electronic terminal. The loudspeaker comprises a first sound production single body and a second sound production single body which is transversely arranged in the same horizontal plane as the first sound production single body, wherein the first sound production single body comprises a first magnetic circuit system and a first vibration system which is fixed on the first magnetic circuit system, and the second sound production single body comprises a second magnetic circuit system and a second vibration system; and the first magnetic circuit system comprises a first magnet yoke, and the second magnetic circuit system comprises a second magnet yoke which is arranged in parallel with the first magnet yoke, the first magnet yoke and the second magnet yoke being integrally formed. The acoustic performance of the loudspeaker in the present embodiment can be improved by means of the two sound production single bodies; the first sound production single body and the second sound production single body are placed in the same horizontal plane, such that the thickness of the loudspeaker in the present embodiment can be reduced, thereby adapting to the development trend of mobile terminals becoming thinner and thinner; and the first magnet yoke and the second magnet yoke are integrally formed, so that the first sound production single body and the second sound production single body can be connected into a whole.
