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

[0030] Such as figure 1 As shown, as a first preferred embodiment, a circuit board with opening and closing holes includes a circuit board main body 1, and terminals 2 are respectively provided on one side and two ends of the circuit board main body 1, and solder joints are provided on the terminals 2. 3. An opening and closing hole 5 is opened in the middle of the circuit board main body 1, and the opening and closing hole 5 is rectangular.

[0031] Such as figure 2 As shown, a receiver with a circuit board with opening and closing holes includes a casing and the above-mentioned circuit board main body 1, the casing includes a bottom box 7 and a box cover 8 arranged at the top of the bottom box 7, the bottom box 7 A sound transmission opening is opened on one side panel, and the circuit board main body 1 is arranged on the outside of the other side panel of the bottom box 7 .

[0032] The shell is in the shape of a cuboid, and a wire slot 9 is provided at a position corres...

Embodiment 2

[0035] Such as image 3 As shown, as a preferred embodiment, the rest is the same as Embodiment 1, the difference is that it also includes an opening and closing mechanism arranged on the circuit board main body 1, the opening and closing hole 5 is circular, and the opening and closing hole 5 The hole diameter is 0.1mm. The opening and closing mechanism includes a cover plate 6 and a pole 4. The cover plate 6 is movably arranged on the circuit board main body 1 through the pole 4. The size of the cover plate 6 is larger than that of the opening. Obturator 5 sizes.

[0036] In the above-mentioned embodiment 2, an opening and closing mechanism is added to the main body 1 of the circuit board. The opening and closing mechanism can open and close the opening and closing hole 1 to achieve the effect of enhancing the low frequency and meet various requirements.

Embodiment 3

[0038] Such as Figure 4 As shown, as yet another preferred embodiment, the rest is the same as Embodiment 1 or 2, except that a groove 11 is opened on the cover plate 6 .

[0039] In the above-mentioned embodiment 3, during the use of the receiver, the opening or closing of the cover plate 6 and the opening and closing hole 5 can be realized by toggling the groove 11. When the cover plate 6 is opened, the opening and closing hole of the circuit board body 1 5 can enhance the low frequency. When the cover plate 6 is closed, the opening and closing hole 5 of the circuit board body 1 is closed, which can increase the high frequency, and it can be adjusted according to the needs, which is more humanized.

Abstract

The invention relates to a circuit board with an open and close hole and a telephone receiver thereof. The circuit board comprises a circuit board main body, wherein terminals are respectively arranged at the two ends of one face of the circuit board main body; each terminal is provided with welding spots; the open and close hole is formed in the middle of the circuit board main body; the circuit board main body is provided with the open and close hole, the structure is simple and reasonable; low-frequency output can be enhanced; sound output is enriched; the requirements of people in daily life can be satisfied; an opening and closing mechanism is arranged on the circuit board main body; a groove or a bump is arranged on a cover plate of the opening and closing mechanism; in a using process of the telephone receiver, the condition that the cover plate and the open and close hole are opened and closed is realized through shifting the groove and the bump; when the cover plate is opened, the lower frequency of the open and close hole of the circuit board main body can be enhanced; when the cover plate is closed, the open and close hole of the circuit board main body is closed, so that high frequency can be improved, and the circuit board is more humanized; a seal ring is arranged on the periphery of the open and close hole; and when the cover plate is closed, the tightness is better, so that the sound quality is improved.

Description

technical field [0001] The invention relates to a circuit board and a receiver thereof, in particular to a circuit board with opening and closing holes for enhancing low frequency and a receiver thereof. 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 transmissi...
