Abstract: The present invention discloses a moving-coil electroacoustic transducer, which is bar-shaped, and comprises a vibration system. The vibration system comprises a vibration diaphragm, a bar-shaped acoustic coil, an acoustic coil support, and two plucked members. The acoustic coil sleeves the acoustic coil support and is combined with the vibration diaphragm through the acoustic coil support. The acoustic coil support is integrally thrilled, and comprises an acoustic coil mounting portion located in the middle, plucked member mounting portions located at the two ends, and a support portion disposed between two long-axis edges of the acoustic coil mounting portion. In such a design, by using the integrally formed acoustic coil support, and disposing the plucked member mounting portions at the two ends of the acoustic coil support, a support portion is disposed between two long-axis edges of the acoustic coil mounting portion, and the acoustic coil support can be formed integrally, so that the problems of biased vibration and deformation on the long-axis side is solved, and meanwhile the manufacturing process is simplified, thereby making the manufacturing simpler.

Abstract: Disclosed is a loudspeaker module, which comprises a loudspeaker unit and a module housing for accommodating the loudspeaker unit. The loudspeaker unit comprises a magnetic circuit assembly and a vibration assembly. The module housing comprises a polycarbonate plastic material layer and an elastomeric material layer having a compression amount. The polycarbonate plastic material layer forms an inner layer of the module housing. The elastomeric material layer is at least partially bonded on the outside of the polycarbonate plastic material layer to form the outer layer of the module housing. The polycarbonate plastic material layer and the elastomeric material layer are formed by double-shot injection molding. The loudspeaker module of the present disclosure can effectively solve the problem of the damage to the module housing caused by inflexible contact with other components of the whole machine, and can utilize the outer layer structure to change the resonance frequency, thereby effectively ameliorating the resonance phenomenon of the module housing and optimizing the product performance.
