Embodiment 1

[0024] see figure 1 , is a schematic structural diagram of a portable power supply device 100 with a sound-absorbing function provided by Embodiment 1 of the present invention. The portable power supply device 100 with sound-absorbing function includes a device casing 10, a circuit board 20 and a sound-absorbing material 30. The device casing 10 has an inner cavity 11, and the circuit board 20 is installed in the inner cavity 11. At least one outer boundary surface of the circuit board 20 is There is a gap 22 between 21 and an inner wall surface (not shown) corresponding to at least one outer boundary surface 21 of the inner cavity 11 , and the sound-absorbing material 30 is located in the gap 22 .

[0025] With the above-mentioned design, the sound-absorbing material 30 is used to absorb the active noise emitted by the electronic components (not shown) on the circuit board 20 when they are in operation, thereby preventing the active noise of the electronic components from bei...

Embodiment 2

[0035] see figure 2 , is a schematic structural diagram of a portable power supply device 200 with a sound-absorbing function provided by Embodiment 2 of the present invention. The difference between a portable power supply device 200 with a sound-absorbing function disclosed in Embodiment 2 of the present invention and a portable power supply device 100 with a sound-absorbing function disclosed in Embodiment 1 of the present invention is that:

[0036] The sound-absorbing material 30 is partially filled between the outer boundary surface 21 of the circuit board 20 and the inner wall surface of the inner cavity 11, that is, the inner wall surface 31 of the sound-absorbing material 30 is attached to the outer boundary surface 21 of the circuit board 20, and the outer wall surface of the sound-absorbing material 30 There is still a space between 32 and the inner wall surface of the inner chamber 11.

[0037] Using the above method, while ensuring the sound absorption function an...

Embodiment 3

[0039] see image 3 , is a schematic structural diagram of a portable power supply device 300 with sound-absorbing function provided by Embodiment 3 of the present invention. The difference between a portable power supply device 300 with a sound-absorbing function disclosed in Embodiment 3 of the present invention and a portable power supply device 100 with a sound-absorbing function disclosed in Embodiment 1 of the present invention is that:

[0040] The sound-absorbing material 30 is partially filled in the gap between the outer boundary surface 21 of the circuit board 20 and the inner wall surface of the inner cavity 11, that is, the outer wall surface 32 of the sound-absorbing material 30 is attached to the inner wall surface of the inner cavity 11, and the sound-absorbing material 30 There is still a gap between the inner wall surface 31 of the circuit board 20 and the outer boundary surface 21 of the circuit board 20 .

[0041] With this layout, in addition to ensuring ...

Abstract

The invention discloses a portable power supply device having a sound-absorbing function. The portable power supply device having the sound-absorbing function comprises a device housing, a circuit board and a sound-absorbing material. The device housing has an inner cavity; the circuit board is arranged in the inner cavity; a gap is arranged between at least one outside interface of the circuit board and a corresponding inner wall surface of the inner cavity; and the sound-absorbing material is arranged in the gap. According to the portable power supply device having the sound-absorbing function, the gap between the at least one outside interface of the circuit board and the corresponding inner wall surface of the inner cavity is provided with the sound-absorbing material, and the sound-absorbing material is utilized to absorb active noise emitted by electric devices on the circuit board, so that the active noise can be prevented from being output to the outer side of the power supply device, and furthermore, the noise can be prevented from being heard by users during sleeping at night, and use experience comfort level of the users can be improved.

Description

technical field [0001] The invention relates to the technical field of power supply charging, in particular to a portable power supply device with a sound-absorbing function. Background technique [0002] Currently, portable power devices (such as power adapters or power chargers, etc.) on the market will emit noise when charging communication devices such as mobile phones, tablet computers or smart watches. The main reason for the above-mentioned noise is that the electronic components (mainly the transformer) inside the portable power supply device will generate active noise when it is working, and the frequency of the active noise generated by it is relatively high, even if the sound itself is very small , but because of the high frequency, it is also very sensitive to the human ear, especially in a quiet environment (for example: in the dead of night), and some special groups of people (for example: users with neurasthenia), it may be Active noise is relatively sensitiv...
