Embodiment 1

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

[0057] Such as 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] Such as 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 t...

Abstract

The invention discloses a receiver and its assembly process. The receiver includes a shell, a diaphragm mechanism and an electromagnetic drive mechanism arranged in the shell. The diaphragm mechanism and the electromagnetic driving device are arranged in the inner cavity of the casing. The diaphragm mechanism has a vibrating plate with one end suspended in the air. The electromagnetic driving mechanism includes a coil and a magnetic field assembly for generating a fixed magnetic field. In the receiver of this structure, the shell is set into two shells, and the fixing frame of the diaphragm mechanism is directly installed on the shell, which has a simple structure and simplifies the installation process. The assembly process is: the first permanent magnet is fixed on the inner wall of the first housing to form the first module; the second permanent magnet and the coil are fixed on the inner wall of the second housing to form the second module; the soft magnet is fixed on the vibration plate on to form a third module. Finally, the assembly of the receiver can be completed by assembling the three modules together, realizing modular installation and improving the assembly efficiency of the receiver.

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, which includes a cover, a bottom plate, a magnetic steel, a coil, an iron core, a diaphragm and an annular isolation cylinder. Wherein, the cover body has a bottom opening, and the bottom plate is arranged on the bottom opening of the cover body to enclose a closed installation cavity; the annular isolation cylinder is fixed on the top surface of the bottom plate, and the dia...
