Problems solved by technology

[0005] The structure of the traditional receiver is simple and single, and the sound waves emitted are also relatively single. However, with the rapid development of electronic products today, people have higher and higher requirements for the functionality of the products, especially for the quality and diversity of the sound. In order to make the entertainment effect Stronger, the development of electroacoustic devices is also accelerated accordingly

Embodiment 1

[0031] like figure 1 As shown, as a first preferred embodiment, a shielding shell includes a bottom box 1 and a box cover 7, the box cover 7 is arranged on the top of the bottom box 1, and the inside of the bottom box 1 is provided with steps, the The bottom box 1 is divided into a front chamber 8 of the bottom box and a rear chamber 2 of the bottom box by the step. The slope of the step forms an angle A with the horizontal plane, and the angle A is 15°.

[0032] A shielded case receiver includes a shielded case, a circuit board 9 and a sound transmission mechanism, the circuit board 9 is arranged on the outer wall of the bottom box 1 , and the sound transmission mechanism is arranged inside the bottom box 1 .

[0033] The sound transmission mechanism includes a diaphragm 6, a diaphragm frame 5, a vibration conducting rod 4 and a vibration device 3, the diaphragm frame 5 is bonded to the step, and the vibration device 3 is arranged behind the bottom box In the cavity 2, the v...

Embodiment 2

[0036] like figure 2 As shown, as the second preferred embodiment, the rest is the same as Embodiment 1, except that 18 through holes 10 are evenly opened on the diaphragm 6, and the through holes 10 are circular.

[0037] In the above-mentioned embodiment 2, the diaphragm 6 is provided with a through hole 10, which can reduce the weight of the diaphragm 6 of the receiver, enhance the high-frequency output of the receiver, and increase the response bandwidth of the receiver.

Embodiment 3

[0039] like image 3 As shown, as the third preferred embodiment, the rest is the same as embodiment 1 or 2, the difference is that the circuit board 9 includes a circuit board main body 11, and terminals 12 are respectively provided at both ends of one side of the circuit board main body 11, Solder spots 13 are provided on the terminals 12 , and an opening and closing hole 15 is opened in the middle of the circuit board main body 11 , and the opening and closing hole 15 is circular.

[0040] In the above-mentioned embodiment 3, the circuit board body 11 is provided with opening and closing holes 15, which has a simple and reasonable structure, can enhance low-frequency output, enrich sound output, is more convenient, and meets the needs of people's daily life.

Abstract

The invention relates to a screening can and a telephone receiver of the screening can. The screening can comprises a bottom box and a box cover, wherein the box cover is arranged on the top of the bottom box, a step is arranged inside the bottom box and divide the bottom box into a bottom box front cavity and a bottom box rear cavity, and the step forms an angle A with the panel. According to the screening can, the step is aslant arranged in the bottom box, so that the size of the bottom box front cavity is reduced, the high frequency output of the telephone receiver is suppressed, dentals of the voice frequency is reduced, and sounds are improved. Through holes are formed in a vibrating diaphragm, so that the weight of the vibrating diaphragm of the telephone receiver is reduced, the high frequency output of the telephone receiver is improved, and the responsive bandwidth of the telephone receiver is increased. Holes capable of opening and closing are formed in a circuit board body, the structure is simple and reasonable, the low frequency output can be improved, and the output of voice is enriched. The telephone receiver is more convenient to use and meets the needs of people in daily life.

Description

technical field [0001] The invention relates to a shielding shell and a receiver thereof, in particular to a shielding shell and a receiver for enhancing high frequency and low frequency. Background technique [0002] Modern life is full of various portable electronic products with sound-generating functions, such as mobile phones, electronic dictionaries, digital recorders, and handheld game consoles. Since the above-mentioned products are very small in size and tend to become smaller and smaller, the space planned for the installation of the receiver on each body is also very limited; however, the installed receiver still hopes to make the best use of it under the restricted conditions. best performance. [0003] Generally, the receiver includes a receiver housing body and a circuit board installed on the outer wall of the receiver housing body. A moving iron sound transmission unit is arranged in the receiver housing body. The moving iron sound transmission unit includes...
