Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is that in the thin receiver in the prior art, when the coil is placed on the root of the reed, the part of the reed that participates in sound generation is small, resulting in the defect that the frequency response of the receiver's sound is low

Embodiment 1

[0055] This embodiment provides a thin receiver, such as Figure 1 to Figure 4 As shown, it includes a casing 1, a diaphragm assembly, a coil 3 and two permanent magnets.

[0056] Wherein, the casing 1 includes a first housing 11 and a second housing 12 respectively having openings, the opening at the bottom of the first housing 11 is opposite to the opening at the top of the second housing 12 and is buckled and fixed to form a closed Install the cavity. Optionally, both the first casing 11 and the second casing 12 are made of high-permeability materials, such as high-permeability nickel alloy materials.

[0057] Such as figure 2 , image 3 and Figure 4 As shown, the diaphragm assembly includes a frame-shaped frame 21, a diaphragm 22 and a sealing film 23. The frame-shaped frame 21 is sandwiched between the openings of the first shell 11 and the second shell 12, for example, by laser welding The bottom opening of the first casing 11 , the frame frame 21 and the top open...

Embodiment 2

[0094] This embodiment provides a thin receiver, which differs from the receiver provided in Embodiment 1 in that:

[0095] Such as Image 6 with Figure 7 As shown, the diaphragm 22 includes a diaphragm body 223 and a reed 224. One end of the diaphragm body 223 is formed on the frame frame 21, and the other end is suspended in the inner cavity of the frame frame 21. The diaphragm body 223 and the frame frame A first gap 24 is formed between the frames 21, the diaphragm body 223 is made of a non-magnetic material, such as a highly elastic lightweight material, such as aluminum-magnesium alloy, aluminum alloy and other materials, and the reed 224 is made of a soft magnetic material; The sealing film 23 is fixed on the diaphragm body 223 and the frame 21 to cover all the first gaps 24 . Optionally, the diaphragm body 223 also includes a first part and a second part similar to the diaphragm in Embodiment 1. Or the sealing film is fixed on the frame frame, the reed and the diap...

Embodiment 3

[0100] This embodiment provides a thin receiver, which differs from the receiver in Embodiment 1 or Embodiment 2 in that:

[0101] On the basis of the technical scheme of embodiment 1 or on the basis of the technical scheme of embodiment 2, such as Figure 11 As shown, two first extensions 213 bent toward the second cavity are provided on the side wall where the frame 21 connects with the wall of the inner hole of the coil 3 . That is, the two ends of the first installation part 211 are respectively provided with a first extension part 213 bent toward the second cavity, the coil 3 is sleeved outside the two first extension parts 213, and the two side walls of the inner hole of the coil 3 They are respectively sealed and fixed with the outer wall surface of a first extension part 213 .

[0102] In this embodiment, by setting the first extension part 213 on the first mounting part of the frame frame 21, the firmness of the sealing connection between the wall surface of the inne...

Abstract

The invention provides a thin-type receiver, comprising a housing, a diaphragm module and a coil. A diaphragm assembly includes a frame, Diaphragm and seal film, since a mounting area is formed between a part of the side wall of the frame and an inner wall surface of the housing, the coil seal is secured to the mounting area and the seal is sleeved outside the frame, and the sealing film is spreadto seal all first gaps between the frame and the diaphragm, thereby dividing the mounting cavity of the housing into two chambers that are side-by-side and do not communicate with each other, boundedby the diaphragm assembly. When the coil is energized and the electromagnetic field generated by the coil interacts with the fixed magnetic field of the permanent magnet in the receiver, the whole diaphragm vibrates, so that when a thin diaphragm is formed on the diaphragm module by snare on line, the diaphragm covered with the sealing diaphragm participates in the sound production, the effectivearea of the diaphragm vibration is maximized, and the frequency response of the receiver is improved.

Description

technical field [0001] The invention relates to the field of acoustic technology, in particular to a thin receiver. Background technique [0002] The receiver is an electro-acoustic device that converts audio electrical signals into audio electrical signals under the condition of no sound leakage. It is widely used in communication terminal equipment such as mobile phones, fixed phones, and earphones to realize audio output. [0003] For example, the receiver disclosed in Chinese patent document CN103067808B includes a lower shell and an upper shell with opposite openings and buckled settings, and the upper shell includes a first shell, a third shell, and a second shell that are connected in sequence; E The shape of the reed is a coil set on the root of the middle arm of the E-shaped reed, and the middle arm protrudes from the suspended end of the coil as a vibrating part; the coil is located in the area between the second shell and the lower shell, and includes The first p...
