Embodiment 1

[0058] This embodiment provides a receiver, such as Figure 1 to Figure 3 As shown, it includes a casing 1 , a diaphragm mechanism 2 , an electromagnetic assembly and a soft magnet 32 ​​.

[0059] Such as figure 1 As shown, the shell 1 includes 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 The body 11 is fastened to form an inner cavity. The diaphragm mechanism 2 is arranged between the openings of the first shell 11 and the second shell 12, and divides the inner cavity of the shell 1 into a first cavity 13 close to the first bottom surface and a second cavity close to the second bottom surface Body 14. That is, the inner cavity of the first housing 11 serves as the first cavity 13 , and the inner cavity of the second housing 12 serves as the second cavity 14 . Both the first housing 11 and the second housing 12 are prefer...

Embodiment 2

[0086] This embodiment provides a receiver, such as Figure 4 As shown, the difference between it and the receiver provided in Embodiment 1 is that the soft magnet 32 ​​is replaced by the second permanent magnet 33, and the corresponding electromagnetic assembly includes a coil 37 arranged in the second cavity 14 and a coil embedded in the coil 37. The stem 36, other structures are the same as those of the receiver in Embodiment 1.

[0087] The receiver of this structure, if the polarity of the bottom one end of the second permanent magnet 33 is the S pole, the polarity of the top end is the N pole; Pass forward electricity to the coil 37, the coil 37 produces an electromagnetic field, and it is towards the second permanent magnet 33 The polarity of one end of the bottom is the S pole, according to the repulsion of the same sex, the second permanent magnet 33 is driven to drive the vibrating plate 22 to vibrate upward; The polarity of the bottom end of the second permanent ma...

Abstract

The invention discloses a receiver and an assembly technique thereof. The receiver comprises a housing, and a vibration film mechanism, a first magnetic body and an electromagnetic assembly, which are arranged in the housing. The first magnetic body is fixed on the surface, towards one side of a second cavity body, of a vibration plate. A fixed frame of the vibration film mechanism is directly fixed on the housing. The electromagnetic assembly is arranged in an inner cavity of the housing, and used for generating electromagnetic driving force for driving the first magnetic body to drive the vibration plate to carry out reciprocating vibration. According to the invention, the housing of the receiver comprises two housing bodies, and the fixed frame of the vibration film mechanism is directly installed on the housing, so parts in the receivers are reduced and the structure and the installation processes of the receiver are simplified. The assembly technique comprises steps that the electromagnetic assembly is pre-fixed on a second housing body so that a first module is formed; the first magnetic body and the vibration film mechanism are pre-fixed so that a second module is formed; the first housing body forms a third module; and finally, by assembling the three modules, the assembly processes of the receiver can be finished, so the modularized installation processes are achieved and the assembly efficiency of the receiver is improved.

Description

technical field [0001] The invention relates to the technical field of acoustic components, in particular to a receiver and an assembly process. 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 d...
