Abstract: A speaker sounding hole device includes a speaker single-unit front cover and a module housing. The speaker single-unit front cover is rectangular, the long edges and/or short edges of the speaker single-unit front cover are provided with open grooves, and the speaker single-unit front cover and the module housing are correspondingly assembled by means of the open grooves. The speaker single-unit front cover provided with the open grooves and the module housing form a front cavity of the speaker sounding hole device. Spaces formed by the open grooves are connected with the front cavity of the speaker sounding hole device to form a sounding channel of the speaker sounding hole device. The device can solve the problems of high cost, long tuning time of the product performance, poor sounding effects and low product efficiency.

Abstract: The loudspeaker module includes a loudspeaker unit including a front cover and a casing engaged together, a vibration system, and a magnetic circuit system received in a space enclosed by the front cover and casing. The loudspeaker module further includes an independent housing enclosing a sealed cavity. The independent housing is provided with an opening communicating the cavity with the exterior. A sidewall of the casing is provided with a rear sound aperture radiating an acoustic wave to a side. The side of the loudspeaker unit provided with the rear sound aperture is sealingly engaged with the independent housing at the opening. A structure of the opening matches with the loudspeaker unit. The rear sound aperture communicates with the cavity. After the loudspeaker unit is engaged with the independent housing, the cavity forms a rear acoustic cavity of the loudspeaker module.

Abstract: The present invention provides a speaker structure, comprising a vibrating component, an electromagnetic component, an casing and an integral washer conductive sheet. The electromagnetic component comprises a central magnet and peripheral magnets which are disposed around the central magnet. The integral washer conductive sheet replaces a washer structure and an conductive sheet structure in a traditional speaker structure and is integrally formed by the washer and an conductive sheet which are combined into one part. The integral washer conductive sheet comprises a washer part and an conductive sheet part, wherein the washer part is disposed on the peripheral magnets and the conductive sheet part extends out of the casing. By adopting the integral washer conductive sheet according to the present invention, those skilled in the art can simplify an internal structure of the speaker, save production materials, simplify molding and assembling procedures, and improve production efficiency.

Abstract: A moving-coil electroacoustic transducer is provided which is bar-shaped and includes a vibration system. The vibration system includes 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 formed; and includes an acoustic coil mounting portion located in the middle, dampening member mounting portions located at the two ends, and a support portion disposed between two long-axis edges of the acoustic coil mounting portion.
