Problems solved by technology

However, limited by the structural design of the switch itself, the switch is often easy to be pressed and trigger a sound
Furthermore, because the switch is often directly arranged on the circuit board in the body, the sound generated when the switch is pressed is very easy to resonate with the internal cavity of the body through the transmission of the circuit board.
In this way, the quality of the electronic device tends to decline, so that the user's comfort level in use and the user's willingness to purchase also decrease correspondingly.

[0035] Please refer to figure 1 , which is a schematic diagram of an electronic device according to a preferred embodiment of the present invention. The electronic device 100 includes bodies 111 and 112 , a switch 120 and a circuit board 130 .

[0036] The body 112 can be expanded or closed relative to the body 111 . In this embodiment, the switch 120 is, for example, a power switch for enabling the electronic device 100 . The switch 120 is disposed at an end corner R of the body 111 and exposed outside the body 111 . Of course, the use and location of the switch 120 are not limited to the example here. In terms of the configuration position of the switch 120 , the switch 120 can be adjusted according to the configuration of each component of the electronic device 100 or the user's convenience in use.

[0037] The circuit board 130 is disposed in the body 111 . Please also refer to Figure 2A and Figure 2B , Figure 2A for figure 1 A schematic diagram of the circuit ...

[0045] Compared with the first embodiment, the circuit board of the electronic device of this embodiment further includes a sound-absorbing component, and the rest of the components that are the same as those of the first embodiment have the same reference numerals, and will not be repeated here.

[0046] Please refer to Figure 5 , which is a cross-sectional view of the circuit board and the switch according to the second embodiment of the present invention. The sound absorbing part 237 of the circuit board 230 covers the sound guide part H. As shown in FIG. The material of the sound absorbing member 237 is, for example, sponge or other materials capable of absorbing sound. When the user presses the switch 120, the sound generated by the switch 120 can not only be derived through the sound guide part H, but also can be further absorbed by the sound-absorbing member 237, so as to avoid the sound from being transmitted by the circuit board 230 and producing with the cavity of ...

Abstract

The invention discloses a circuit board and an electronic device applying the same. The circuit board is used for arranging a switch on the circuit board and comprises a main body, wherein the main body is provided with a sound conductive part; and the switch is arranged above the sound conductive part. The electronic device comprises a body, the switch and the circuit board, wherein the circuit board is arranged in the body; the circuit board comprises the main body which is provided with the sound conductive part; and the switch is exposed out of the body and is arranged above the sound conductive part. Sound produced by the actuation of the switch is conducted by the sound conductive part, which can reduce the rate of generating resonance between the body and the sound transferred by the circuit board.

Description

technical field [0001] The invention relates to a circuit board and an electronic device using the same, in particular to a sound-conducting circuit board and an electronic device using the same. Background technique [0002] As the application of electronic devices becomes more and more common, users' requirements on the quality of electronic devices are increasing day by day. Furthermore, the quality of the electronic device often affects the user's comfort in use and the user's willingness to purchase electronic products. Therefore, how to effectively improve the quality of the electronic device is one of the subjects that related companies are working hard on. [0003] Generally speaking, many switches are often arranged in an electronic device. These switches are used to enable corresponding components to perform specific functions when triggered by being pressed. However, limited by the structural design of the switch itself, the switch tends to make a sound when it ...
