Problems solved by technology

Although the overall thickness of the electro-acoustic composite structure is as thin as several millimeters, it cannot be used for frequent carrying occasions, or even curled to greatly reduce the area, and can not be used for storage or carrying.
Moreover, the circuit driver required to provide high voltage is bulky, and cannot achieve the purpose of being light, thin and small

Abstract

The invention provides a flexible electroacoustic combination structure, a loudspeaker and a manufacturing method thereof. The flexible electroacoustic combination structure uses an electret as vibration membrane material, and conducting material is plated one surface of the vibration membrane material, and a fixing electrode plate is matched in parallel so as to form a main structure. A plurality of longitudinally or transversely bulged gaskets are arranged on the surface of a membrane layer of the fixing electrode plate, and the gaskets are used for supporting the vibration space of the vibration membrane. A working area of the vibration membrane is formed between adjacent gaskets, and in each working area of the vibration membrane, a gap between the fixing electrode plate and the vibration membrane is smaller than the gap of a conventional electrostatic loudspeaker structure. The gaskets between the fixing electrode plate and the vibration membrane are completed by punching with high mass production, thus an accurate space between the fixing electrode plate and the vibration membrane can be maintained so as to improve the quality of sound production. In addition, the invention also provides the loudspeaker of the flexible electroacoustic combination structure and the manufacturing method thereof.

Description

technical field [0001] The present invention relates to a flexible electro-acoustic combined structure, in particular to a flexible electro-acoustic combined structure with an electret material as a diaphragm. The present invention further relates to a loudspeaker including the flexible electro-acoustic composite structure and a manufacturing method of the component. Background technique [0002] Nowadays, vision and hearing are the two most direct sensory responses for human beings. Therefore, scientists have been working hard to develop various regenerative visual and hearing related systems for a long time. At present, including the regeneration method of speakers, the main market is still dominated by dynamic speakers. However, with people's increasing demands on sensory quality in recent years, and 3C products (Computer, Communication, Consumer Electronics) pursuing shortness and thinness, a speaker that is power-saving, light and thin, and can be designed according to...
