Problems solved by technology

Wherein, the back cover is a plate-shaped structure, so that the vibration space of the vibrator is limited to the distance between the bottom wall of the magnetic bowl and the back cover, the vibration space of the vibrator is limited, and the vibration performance of the multifunctional electroacoustic device is not good. To increase the vibration space of the vibrator, it is necessary to reduce the volume of the magnetic circuit system, which will affect the acoustic performance of the multifunctional electroacoustic device

Abstract

The present invention provides a multifunctional electro-acoustic device, which includes a basin frame with a storage space, a rear cover fixed on the basin frame, a vibrator accommodated in the storage space, and a spring plate supporting the vibrator. The vibrator includes a The magnetic bowl on the bottom wall, the rear cover includes an annular fixing part fixed to the basin frame and a side wall extending from the fixing part to the direction of the vibrator for limiting the displacement of the vibrator, the fixing part encloses a hollow part, the The orthographic projection of the bottom wall of the magnetic bowl to the rear cover is located in the hollow portion. The invention can increase the vibration performance and acoustic performance of the electroacoustic device.

Description

technical field [0001] The invention relates to an electroacoustic device, in particular to a multifunctional electroacoustic device. Background technique [0002] With the development of modern electronic product technology, electro-acoustic devices such as speakers are more and more used in various sound-producing products. However, in order to adapt to the development of various electronic products and information communication equipment, the electro-acoustic devices used in such products and equipment need to be more miniaturized, and the cooperation with other components around the electro-acoustic devices is better. compact. [0003] In the electro-acoustic device of the related art, the multi-functional electro-acoustic device includes a basin frame, a rear cover fixed on the basin frame and enclosing a storage space together with the basin frame, a vibrator accommodated in the storage space, and a vibrator for supporting the vibrator. A spring plate, the vibrator i...
