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

[0034] In order to achieve the purpose of the present invention, as Figure 1-6 As shown, in some embodiments of a novel diaphragm with rib structure of the present invention,

[0035] A new type of diaphragm with a rib structure, the diaphragm 21 is used for the receiver, at least one end of the diaphragm 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 is connected to the conductive rod 4 of the receiver Transmission connection, the diaphragm 21 includes a diaphragm body 5 and a reinforcing rib 6 disposed on the diaphragm, the reinforcing rib 6 is a first protruding hull 61 protruding upward and / or a second protruding hull 62 protruding downward. Such as Figure 5 with 6 As shown, the first convex hull 61 and the second convex hull 62 include a side wall 63 and an end portion 64. The side wall 63 and the extending direction of the diaphragm body 5 form an included angle of 3...

Abstract

The invention discloses a novel vibration film with a reinforcing rib structure. The vibration film is used as a receiver, wherein at least one end of the vibration film is connected with a vibration film bracket, the vibration film bracket is fixedly connected with a receiver shell, and one end of the vibration film is in transmission connection with a receiver transmission rod; the vibration film comprises a vibration film body and a reinforcing rib arranged on the vibration film, and the reinforcing rib is a first convex closure upwardly protruded and/or a second convex closure upwardly protruded. The novel vibration film is simple in structure, under the same-thickness vibration film, the vibration film with the reinforcing rib structure is better in vibration intensity and greater in vibration amplitude and can be steadily and smoothly vibrated and effectively ensured in the sound quality of the receiver, thus the novel vibration film is applied to the different-type and different-size receivers.

Description

technical field [0001] The invention relates to a vibrating membrane of a receiver, in particular to a novel vibrating membrane with a rib structure. 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 vi...
