Technical Field
[0001] The utility model relates to the technical field of sound-to-electricity conversion equipment, and in particular to a wearable electronic device with a shock-absorbing and noise-reducing structure. Background Art
[0002] With the advancement of technology, AR / VR devices and headphones are becoming increasingly commonplace in our lives. However, these devices often suffer from issues such as poor acoustic performance and noticeable vibration, which impact the user experience. To improve the acoustic performance of these electronic devices, sound-absorbing materials (such as porous particles or blocks) are often added to the acoustic cavity of the speaker.
[0003] However, in order to facilitate the wearing and carrying of the above-mentioned electronic products, it is necessary to further compress the product volume and reduce the space occupied by the speaker. Accordingly, the volume of the sound cavity in the speaker that can be filled with sound-absorbing material is further compressed, and the technical solution of filling the speaker with sound-absorbing material to improve the acoustic performance will not be realized. Utility Model Content
[0004] The purpose of the utility model is to provide a wearable electronic device with a shock-absorbing and noise-reducing structure. By attaching a flexible sound-absorbing sheet to the outer wall of the speaker, the problem that there is currently no space in the speaker for filling with sound-absorbing material to improve the acoustic performance of the electronic device is solved.
[0005] The above technical objectives of the present invention are mainly achieved through the following technical solutions:

[0007] shell;
[0008] a sound-generating unit, the sound-generating unit being installed in the housing;
[0009] A flexible sound-absorbing sheet with a porous structure is provided on the sound-emitting unit to cover at least a portion of the outer side wall of the sound-emitting unit.
[0010] In a preferred embodiment of the present invention, the flexible sound-absorbing sheet is a sheet-like structure made of nanoporous material and has flexibility.
[0011] In a preferred embodiment of the present invention, the nanoporous material is at least one of zeolite powder flakes, aerogel, foam, and sound-absorbing cotton.
[0012] In a preferred embodiment of the present invention, the sound-emitting unit is a speaker module.
[0013] In a preferred embodiment of the present invention, the flexible sound-absorbing sheet is fixed to the outer side wall of the housing of the speaker module by bonding.
[0014] In a preferred embodiment of the present invention, the speaker module has a sound hole, and the housing is provided with a sound outlet hole opposite to the sound hole.
[0015] In a preferred embodiment of the present invention, the housing includes an upper cover and a lower cover that are buckled together, a receiving cavity is formed between the upper cover and the lower cover, and the speaker module is located in the receiving cavity.
[0016] In a preferred embodiment of the present invention, the wearable electronic device is an earphone having the sound unit.
[0017] In a preferred embodiment of the present invention, the wearable electronic device is glasses having the sound unit.

[0037] like Figure 1 As shown, the present invention provides a wearable electronic device with a vibration-absorbing and noise-reducing structure, which includes a housing 10, a sound-emitting unit 20, and a flexible sound-absorbing sheet 30. The sound-emitting unit 20 is mounted within the housing 10; the flexible sound-absorbing sheet 30 has a porous structure inside and is disposed on the sound-emitting unit 20 to cover at least a portion of the outer wall of the sound-emitting unit 20.
[0038] The wearable electronic device with a shock-absorbing and noise-reducing structure described in the present invention can reduce the vibration of the electronic device and reduce noise. The flexible sound-absorbing sheet 30 can absorb and disperse vibration energy through its internal porous structure and its own flexibility, effectively reducing the mechanical vibration generated by the sound-emitting unit 20 and preventing the vibration from being transmitted to surrounding objects; it can also scatter and absorb sound waves through the interaction between its complex internal structure and sound waves, thereby reducing the intensity of the sound and achieving a noise reduction effect.
[0039] The wearable electronic device with a shock-absorbing and noise-reducing structure described in the present invention can improve the acoustic performance of the electronic device. The flexible sound-absorbing sheet 30 with a porous structure has the characteristics of high sound absorption coefficient and low acoustic impedance, can effectively absorb and disperse sound waves, reduce resonance and standing waves in the sound cavity, and thus improve sound quality and clarity.
[0040] The wearable electronic device with a shock-absorbing and noise-reducing structure described in the present invention can optimize the sound cavity volume of the electronic device. In wearable electronic devices such as glasses and headphones, the space is limited. The flexible sound-absorbing sheet 30 with a porous structure can achieve the effect of virtually increasing the sound cavity without increasing the actual physical volume, thereby improving the loudness and low-frequency performance of the sound in a limited space.
[0041] The following will describe in detail the specific structure of each part of the wearable electronic device with a shock-absorbing and noise-reducing structure of the present invention, as well as the position and connection relationship between the parts.
[0042] The electronic device of the present invention comprises a housing 10, such as Figure 1 As shown, in this embodiment, the housing 10 includes an upper cover 11 and a lower cover 12 that interlock, with a cavity formed between the upper cover 11 and the lower cover 12 for mounting various functional modules of the electronic device. In other embodiments of the present invention, the housing 10 of the electronic device may also be an integrated structure, as long as the housing 10 has a cavity for mounting various functional modules.
[0043] A sound unit 20 is installed in the accommodating cavity. The sound unit 20 is usually a packaged speaker module or a built-in speaker box. In order to adapt to the shape of the housing 10 and minimize the volume of the electronic device, the shape of the packaged speaker module or the shape of the built-in speaker box matches the shape of the accommodating cavity at its installation position.
[0044] The sound unit 20 is provided with a flexible sound-absorbing sheet 30. The sheet 30 has a porous structure and a certain degree of flexibility, allowing for appropriate bending. The sheet 30 wraps around the periphery of the sound unit 20 (speaker module or built-in speaker), covering at least a portion of the outer wall of the sound unit 20. The flexibility of the sheet 30 allows it to bend and effectively cover the sound unit 20.
[0045] Preferably, the flexible sound-absorbing sheet 30 covers as much outer wall of the sound-emitting unit 20 as possible, and only necessary parts of the sound-emitting unit 20 are exposed (such as the sound hole 21, the fixing seat, etc.).
[0046] Furthermore, the flexible sound absorbing sheet 30 is fixed to the outer wall of the speaker module or the built-in speaker box by bonding. In other embodiments of the present invention, the flexible sound absorbing sheet 30 can also be fixed in other ways, such as by micro screws.
[0047] Further, such as Figure 1 As shown, the sound unit 20 (speaker module or built-in speaker) has a sound hole 21, and the housing 10 is provided with a sound outlet hole 13 opposite to the sound hole 21. The sound generated by the sound unit 20 through vibration can be transmitted to the wearer's ear through the sound hole 21 and the sound outlet hole 13.
[0048] The structure and technical effects of the preferred embodiment of the wearable electronic device with a shock-absorbing and noise-reducing structure described in the present invention will be further described below.
[0049] According to one embodiment of the present invention, the flexible sound-absorbing sheet 30 is a flexible sheet structure made of a nanoporous material; wherein the nanoporous material is preferably at least one of zeolite powder sheet, aerogel, foam, and sound-absorbing cotton.
