The present disclosure relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present disclosure and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.

Electroacoustic drivers that can be utilized in loudspeaker systems that utilize bidirectional force electromagnet transducers or piezoelectric transducers. The electroacoustic drivers can include motion amplifiers such as lever arms. The electroacoustic drivers can be used at all audio frequencies including frequencies below 500 Hz.

The present disclosure provides an acoustic device. The acoustic device may include a shell including a first accommodation cavity, a speaker configured in the first accommodation cavity. The speaker may include one or more magnetic circuit assemblies, a voice coil, a vibration assembly, and a vibration transmission plate. The one or more magnetic circuit assemblies may form a magnetic gap. One end of the voice coil may be arranged in a magnetic gap, and another end of the voice coil may be connected with the vibration assembly. The vibration assembly may be connected with the vibration transmission plate, and the vibration transmission plate may be connected with the shell.

The present disclosure provides a bone conduction-based clamping device and processing method. The device includes a handle, a clamping structure provided on one side of the handle, and a sound generating processor provided inside the handle. A user puts food into his mouth cavity by clamping the food with the clamping structure, and a vibration signal generated by the sound generating processor is transmitted to the food by the clamping structure and then transmitted to the user’s auditory system by an oral tissue or teeth of the user, thereby avoiding the pressing feeling caused by wearing in a pressing manner. Putting the clamping structure into the user’s mouth cavity can also reduce sound leakage, improve sound quality and protect privacy. In addition, the food can be replaced by the clamping structure, thereby guaranteeing hygiene and health, improving the usage rate of the device, and realizing multi-user sharing.
