Abstract: The present invention discloses a speaker module. The speaker module comprises an inner cavity defined by a shell, and a first induction coil. A single speaker piece is provided in the inner cavity of the shell, the first induction coil is configured to be electrically connected with a terminal device, and a second induction coil, which corresponds to the first induction coil and is configured to be electrically connected with a voice coil in the single speaker piece, is also provided on the shell. According to the speaker module, an output end of a complete machine and the voice coil are conducted through the first induction coil and the second induction coil; and by the adoption of such a structure, the space of the module can be greatly saved, and a lighter and thinner complete machine can be developed. In addition, the problems, such as poor performance due to the change of the resistance value in a traditional electro-acoustic connection way, can be solved. By the adoption of the structure, the first induction coil is allowed to be provided outside the inner cavity, the shell can be sealed at a time, wiring from the outside to the inside is not needed any more. In this way, secondary sealing of a lead position is avoided, production and transportation of the speaker module are greatly simplified, and assembly between the speaker module and the terminal device is also greatly simplified.

Abstract: A speaker module is disclosed, which comprises an inner cavity defined by a shell, and a magnetic circuit system and a vibrating system arranged inside the inner cavity, wherein the vibrating system comprises a vibrating diaphragm fixed in the inner cavity, a voice coil is fixed to a lower end of the vibrating diaphragm, a first induction coil is provided to an upper end of the vibrating diaphragm, the voice coil is electrically connected with the first induction coil via its down-lead, and a second induction coil is provided above the first induction coil for electrically connecting a terminal device. When the speaker module operates, the terminal device conducts a current signal of an external audio to the second induction coil, so that the second induction coil generates a magnetic field which changes along with the change of the audio signal current.
