Micro loudspeaker and electronic device utilizing same

Abstract

The invention discloses a micro loudspeaker. A shell of the micro loudspeaker comprises an upper side and a lower side. Electrical connecting pieces in elastic slice-structures comprise first deformation portions, second deformation portions and connecting portions, wherein the first deformation portions are arranged on the upper side of the shell and are upwardly bent, the second deformation portions are arranged on the lower side of the shell and are downwardly bent, the connecting portions are used for electrically connecting the first deformation portions with the second deformation portions, and first conductivity portions and second conductivity portions are respectively arranged at tops of the first deformation portions and bottoms of the second deformation portions. As the assembling mode of the micro loudspeaker is variable, adaptability of the micro loudspeaker with an electronic device in assembling is improved. The electronic device comprises the micro loudspeaker, an outer casing, a first sound hole and circuit boards. The first conductivity portions or the second conductivity portions of the micro loudspeaker are electrically connected with the circuit boards. Design requirements of the electronic device utilizing the micro loudspeaker are met in use.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a micro-speaker and an electronic device using the micro-speaker. Background technique [0002] The micro-speaker includes a vibrating system, a casing for accommodating and fixing the vibrating system, and an electrical connector for electrically connecting the internal circuit and the external circuit. The vibration system includes a diaphragm and a voice coil combined with the lower side of the diaphragm, and the casing includes an upper side combined with the diaphragm and a lower side opposite to the upper side. The electrical connector includes a conductive part electrically connected to an external circuit. In the prior art, the conductive part is usually disposed on the lower surface of the casing. The micro-speaker with this structure is assembled with the electronic device of the terminal in a single way, and the position of the micro-speaker in the electronic device cannot ...

AI Technical Summary

Problems solved by technology

The micro-speaker with this structure is assembled with the terminal electronic device in a single way, and the position of the micro-speaker in the electronic device cannot be flexibly adjusted, which is not conducive to improving the adaptability of the micro-speaker to different electronic devices.

[0003] Furthermore, for electronic devices such as mobile phones that need to be installed with micro-speakers, the installation position of the micro-speakers needs to be determined according to the internal space of the electronic device. It is difficult for electronic devices to meet certain performance requirements, such as product thickness, size, etc.
