Embodiment 1

[0056] This embodiment provides a receiver, such as figure 1 As shown, it includes a casing 1 , a diaphragm mechanism 2 and a driving mechanism 3 .

[0057] like figure 1 As shown, the shell 1 has a first shell 11 made of a first bottom surface and a side wall, and a second shell 12 made of a second bottom surface and a side wall; the second shell 12 is detachably connected to the first shell 11 is snapped together to form an inner cavity, and the first shell 11 and the second shell 12 are fixedly connected, for example, by means of glue or spot welding. Preferably, both the first casing 11 and the second casing 12 are made of high magnetic permeability magnetic alloy.

[0058] like figure 1 As shown, the diaphragm mechanism 2 is arranged between the openings of the first housing 11 and the second housing 12, and divides the inner cavity of the housing 1 into a first cavity 13 close to the first bottom surface and a first cavity 13 close to the second bottom surface. Tw...

Abstract

The invention discloses a receiver and its assembly process. The receiver includes a shell, a diaphragm mechanism and a driving mechanism. The diaphragm mechanism and the drive mechanism are arranged in the inner cavity of the shell; the diaphragm mechanism has a vibrating plate, and the drive mechanism has a first permanent magnet, a first polar arm, a second polar arm, and a coil; the first polar arm, the second polar arm The installation space enclosed between the two polar arms and the vibrating plate provides enough vibration space for the suspended first permanent magnet, which reduces the height of the receiver; the magnetic field loop formed by the first polar arm and the second polar arm passes through Through the first permanent magnet, the force on it is stronger, and the sensitivity is improved. The assembly process includes the following steps: installing the magnetic component on the inner wall of the second housing, and covering the coil, fixing the first permanent magnet on the vibration plate through the first connecting piece; installing the diaphragm mechanism on the housing , so that the first permanent magnet protrudes into the installation area enclosed by the polarity arm; the first casing and the second casing can be snapped together, which simplifies the installation process and improves the sensitivity.

Description

technical field [0001] The invention relates to the technical field of receivers, in particular to a receiver and an assembly process thereof. Background technique [0002] The receiver is an electroacoustic device that converts audio electrical signals into audio signals without sound leakage. It is widely used in communication terminal equipment such as mobile phones, fixed phones, and earphones to realize audio output. [0003] With the continuous development of mobile devices, the structure of the receiver is constantly updated. For example, Japanese patent document JP10301573A discloses a receiver, such as Figure 5 As shown, it includes a cover, a bottom plate, an iron core, a coil, a magnetic steel, a diaphragm and an annular isolation cylinder. Among them, the bottom of the cover is open, and the bottom plate is arranged on the bottom opening of the cover to enclose a closed installation cavity; the annular isolation cylinder is fixed on the upper surface of the bott...
