Problems solved by technology

The problems caused by the above two diaphragm units are: first, the connection is low in firmness, which reduces the service life of the diaphragm unit; However, due to the very small volume of the receiver and the diaphragm unit, the processing personnel need to use a microscope or a magnifying glass to operate, so the processing is more difficult, and it also reduces the amplitude range of the diaphragm, making the sound The low-frequency output is not ideal. Although in the prior art, the vibration amplitude of the diaphragm is increased by making the connecting beam thinner and thinner, so as to achieve the effect of supplementing the low-frequency output, but this will inevitably sacrifice the obtained reinforcement. sexual advantage

Embodiment 1

[0026] Such as Figure 4-7 As shown, the receiver with a multi-piece diaphragm in this embodiment includes a housing 2, a sounding unit 3 and a driving device, the sounding unit 3 is the sounding tube 3 shown in the figure, and the driving device includes a diaphragm unit, Also includes circuit board 4, iron core 51, magnet 52, coil 53 and armature 54, and this diaphragm unit comprises: diaphragm support 11, and it is fixedly connected with the inner wall of housing 2; The membrane bracket 11 is fixedly connected; the diaphragm 12 is fixedly connected with the other end of the connecting part 13 . As shown in the figure, the connection part 13 is implemented in the form of a connecting plate in this embodiment, but of course it can also be implemented in a shape such as a rod or a block.

[0027] The above-mentioned connecting portion 13 is made of plastic material or non-magnetic metal material. The plastic material may include various hardness plastics and rubber and other...

Embodiment 2

[0037] Others are the same as those described in Embodiment 1, except that the above-mentioned connecting portion 13 and the diaphragm support 11 and the diaphragm 12 are implemented by welding instead of bonding, so that the materials can achieve an interatomic bond And form a permanent connection, but the solder joints should be as many as possible. However, after the welding is completed, it is necessary to check whether there is a weld, and if there is a weld, it needs to be repaired. In addition, it is best to conduct a firmness test as well, which is more beneficial to the implementation effect.

Embodiment 3

[0039] Others are the same as those described in Embodiment 1, except that: there are more than one connection part 13, so that the firmness of the connection is strengthened, but a little low frequency may be sacrificed, which needs to be selected according to the user's needs.

[0040] The working principle of the present invention is introduced below:

[0041] When the receiver is working, the diaphragm 12 is driven by the driving device to vibrate, and the connecting part 13, the diaphragm 12, and the diaphragm support 11 are designed in sections to form at least three diaphragm units, and the connecting parts are connected to the diaphragm respectively. It is fixedly connected with the diaphragm bracket, which can increase the amplitude of the diaphragm and obtain better low frequency while achieving better firmness.

[0042] The beneficial effects of adopting the above technical scheme are:

[0043] 1. In the present invention, at least one connection part is added betw...

Abstract

The invention discloses a receiver with a multi-piece type vibration film. The receiver with the multi-piece type vibration film comprises a shell body, a sound production unit and a drive device. The drive device comprises a vibration film unit. The vibration film unit comprises a vibration film support which is fixedly connected with the inner wall of the shell body, at least one connecting part and a vibration film which is fixedly connected with the other end of the connecting part, and one end of the connecting part is fixedly connected with the vibration film support. The receiver with the multi-piece type vibration film is not only capable of guaranteeing soundness of connecting and reducing process difficulties, but also capable of not scarifying low frequency.

Description

technical field [0001] The invention relates to a receiver, in particular to a receiver with a multi-piece diaphragm. 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 unit. Among them, the diaphragm unit 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. High and low, the greater the vibrating r...
