Problems solved by technology

However, when the thickness of the diaphragm is ensured, the vibration strength of the diaphragm is difficult to be guaranteed
If the diaphragm is too thin, when the diaphragm vibrates, it is likely to form a wave-shaped vibration, which will cause noise interference to the receiver

Embodiment Construction

[0027] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] In order to achieve the purpose of the present invention, in some embodiments of the novel diaphragm and receiver of the present invention,

[0029] A new type of diaphragm, characterized in that the diaphragm 21 is used for the receiver, at least one end of the diaphragm 21 is connected to the diaphragm support 22, the diaphragm support 22 is fixedly connected to the shell 1 of the receiver, and one end of the diaphragm 21 is connected to the conductive rod of the receiver 4 transmission connection, the longitudinal section of the diaphragm 21 is a downward circular arc, that is, it is gradually concave from the edge of the diaphragm 21 to the center of the diaphragm 21. The center of the diaphragm 21 is provided with a conduction hole 5 , and the conduction rod 4 is connected to the diaphragm 21 through the conduction hole 5 . The c...

Abstract

The invention discloses a novel vibrating diaphragm and a telephone receiver. The vibrating diaphragm is used for the telephone receiver, at least one end of the vibrating diaphragm is connected with a vibrating diaphragm support, the vibrating diaphragm support is fixedly connected with a housing of the telephone receiver, one end of the vibrating diaphragm is in drive connection with a conduction rod, and the longitudinal section of the vibrating diaphragm is in a shape of a downward circular arc, namely the longitudinal section is gradually sunken from the edge of the vibrating diaphragm to the center of the vibrating diaphragm. The novel vibrating diaphragm is simple in structure, the concave vibrating diaphragm is higher in vibrating strength and larger in vibrating amplitude on the premise of the same thickness, the stable and firm vibration of the vibrating diaphragm can be effectively ensured, and the sound quality of the telephone receiver can be effectively ensured.

Description

technical field [0001] The invention specifically relates to a novel vibrating membrane and a receiver. Background technique [0002] The receiver, also known as the earpiece, is an electroacoustic device that converts audio electrical signals into sound signals without sound leakage. It is widely used in communication terminal equipment such as mobile phones, fixed phones, and earphones to realize audio, such as voice and music. Waiting for replay. In the receiver, the conversion of the electrical signal to the sound signal is mainly completed by an internal drive device, which mainly includes an armature, a coil, a magnet, and a diaphragm. Among them, the diaphragm is a more important part, its function is to compress the air in the front cavity through vibration, drive the air to vibrate and output the sound from the sound unit, and the amplitude range of the diaphragm also determines the sound frequency. , the larger the vibrating range of the diaphragm, the more advan...
