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: Disclosed is a structure for detecting the vibration displacement of a speaker, including: a vibration system having a movable pole plate; a magnetic circuit system; and a fixed pole plate provided under the vibration system and opposite to the movable pole plate, the movable pole plate and the fixed pole plate constituting a capacitor. Also disclosed is an acoustoelectric inter-conversion dual-effect device, further including an impedance transformer connected to the capacitor and including a field effect transistor and a diode. In the present invention, a movable pole plate of a capacitor is provided on a vibration system and a fixed pole plate is provided under the vibration system and fixed in position. When the vibration system vibrates, the change in capacitance is detected to calculate the actual displacement of the vibration system, which can reduce the power of the speaker device when the actual displacement of the vibration system exceeds a safety threshold. For an electronic device adopting such a speaker structure, the displacement of the vibration system of a speaker product can be detected in real time at the system end of the electronic device.
