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.

Abstract: The present invention discloses a speaker module, comprising: a speaker assembly, a module shell and a front cover. The module shell is configured to bear the speaker assembly, and comprises a first shell and a second shell, wherein the first shell is doped with a thermally conductive filler. The front cover is configured to cooperate with the module shell to encapsulate the speaker assembly. The speaker module provided by the present invention can quickly discharge heat generated by the speaker assembly during operation through the module shell to prevent overheat of the speaker assembly, thereby avoiding performance loss of a speaker due to high temperature.

Abstract: Disclosed are a vibration diaphragm and a speaker device. The vibration diaphragm includes a vibration diaphragm body portion and a reinforcement portion incorporated at the center of the vibration diaphragm body portion and including a carbon fiber cloth layer. The vibration diaphragm in the present invention employs a carbon fiber cloth with a relatively light weight and relatively high rigidity as the reinforcement portion, which can sufficiently satisfy the requirements to the vibration diaphragm acoustic performance by the speaker device.

Abstract: The present invention discloses a speaker device capable of restraining polarization, a method for adjusting a diaphragm balance position of the speaker device and a method for adjusting diaphragm compliance performance of the speaker device. The speaker device comprises a vibration system, a magnetic circuit system, a shell accommodating the vibration system and the magnetic circuit system, a first electret layer, a second electret layer and a third electret layer, wherein the first electret layer, the second electret layer and the third electret layer have the same electric charge polarity; the first electret layer is attached to the vibration system; the second electret layer is attached to a first fixing component above the vibration system and opposite to the first electret layer; the third electret layer is attached to a second fixing component below the vibration system and opposite to the first electret layer; and the first electret layer, the second electret layer and the third electret layer are parallel to one another. In the present invention, an electrostatic field force is adopted to restrain the polarization of a diaphragm in a vibration direction.
