[0002] This application claims priority to Chinese Patent Application No. 202423069750.2, filed on December 12, 2024, and incorporates the entire contents of the aforementioned patent application as part of this application. Technical Field
[0003] This application relates to the field of sound-to-electric conversion equipment technology, and in particular to a wearable electronic device with a vibration damping and noise reduction structure. Background Technology
[0004] With the development of technology, AR / VR devices and headphones are becoming increasingly widely used in people's lives. However, these devices often suffer from poor acoustic performance and noticeable vibrations, affecting the user experience. To improve the acoustic performance of these electronic devices, sound-absorbing materials (sound-absorbing particles or blocks made of porous materials) are usually filled into part of the acoustic cavity of the speaker.
[0005] However, in order to facilitate the wearing and carrying of the aforementioned electronic products, it is necessary to further compress the product size and reduce the space occupied by the speaker. Consequently, the volume of the acoustic cavity that can be filled with sound-absorbing material inside the speaker is further compressed, and the technical solution of filling the speaker with sound-absorbing material to improve acoustic performance will not be realized. Summary of the Invention
[0006] The purpose of this application is to provide a wearable electronic device with a shock absorption and noise reduction structure, which solves the problem that there is currently no space inside the speaker to fill with sound-absorbing material to improve the acoustic performance of electronic devices by attaching a flexible sound-absorbing sheet to the outer wall of the speaker.
[0007] The above-mentioned technical objectives of this application are mainly achieved through the following technical solutions:
[0008] This application provides a wearable electronic device with a shock-absorbing and noise-reducing structure, comprising a housing, a sound-generating unit, and a flexible sound-absorbing sheet with a porous structure. The sound-generating unit is installed inside the housing, and the flexible sound-absorbing sheet is disposed on the sound-generating unit to cover at least a portion of the outer wall of the sound-generating unit.
[0009] In one optional embodiment of this application, the flexible sound-absorbing sheet is a flexible sheet structure made of nanoporous material.
[0010] In one optional embodiment of this application, the nanoporous material is at least one of zeolite flakes, aerogel, foam, and sound-absorbing cotton.
[0011] In one optional embodiment of this application, the sound-generating unit is a speaker module.
[0012] In an optional embodiment of this application, the flexible sound-absorbing sheet is fixed to the outer wall of the speaker module housing by adhesive bonding.
[0013] In one optional embodiment of this application, the speaker module has a sound hole, and the housing has a sound outlet hole opposite to the sound hole.
[0014] In one optional embodiment of this application, the housing includes a snap-fit upper cover and a lower cover, with a receiving cavity formed between the upper cover and the lower cover, and the speaker module located within the receiving cavity.
[0015] In one alternative embodiment of this application, the wearable electronic device is an earphone having the sound-generating unit.
[0016] In one alternative embodiment of this application, the wearable electronic device is a pair of glasses having the sound-emitting unit.
[0017] In an optional embodiment of this application, the sound-generating unit and the flexible sound-absorbing sheet are disposed inside the temple of the eyeglasses.
[0018] Compared with the prior art, the technical solution described in this application has the following features and advantages:
[0019] 1. Improve the acoustic performance of electronic devices: Flexible sound-absorbing sheets made of nanoporous materials have the characteristics of high sound absorption coefficient and low acoustic impedance, which can effectively absorb and disperse sound waves, reduce resonance and standing waves in the sound cavity, thereby improving sound quality and clarity.
[0020] 2. Sound cavity volume optimization: In wearable electronic devices such as glasses and headphones, space is limited. Flexible sound-absorbing sheets with porous structures can achieve the effect of virtually enlarging the sound cavity without increasing the actual physical volume, thereby improving the loudness and low-frequency performance of the sound within a limited space.
[0021] 3. Vibration reduction and noise reduction: Flexible sound-absorbing sheets can absorb and disperse vibration energy through their internal porous structure and flexibility, effectively reducing the mechanical vibration generated by the sound-generating unit and preventing vibration from being transmitted to surrounding objects; they can also scatter and absorb sound waves through their complex internal structure and the interaction of sound waves, thereby reducing the intensity of the sound and achieving a noise reduction effect.
[0022] 4. Sound guidance: By precisely designing the structure of nanoporous materials, it is possible to accurately guide and control sound waves, thereby improving sound localization and spatial perception, and providing users with a more immersive listening experience.
[0023] 5. Durability and adaptability: Nanoporous materials typically have good durability and adaptability, and can adapt to different temperatures, humidity and environmental conditions, ensuring long-term stability of sound performance in the acoustic cavity. Attached Figure Description

[0033] As shown in Figures 1 to 3, this application provides a wearable electronic device with a shock absorption and noise reduction structure, which includes a housing 10, a sound-generating unit 20, and a flexible sound-absorbing sheet 30. The sound-generating unit 20 is installed inside the housing 10; the flexible sound-absorbing sheet 30 has a porous structure inside and is disposed on the sound-generating unit 20 to cover at least a portion of the outer wall of the sound-generating unit 20.
[0034] The wearable electronic device with vibration damping and noise reduction structure described in this application can reduce the vibration of electronic devices 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-generating unit 20 and preventing the vibration from being transmitted to surrounding objects. It can also scatter and absorb sound waves through its complex internal structure and the interaction of sound waves, thereby reducing the intensity of the sound and achieving a noise reduction effect.
[0035] The wearable electronic device with a vibration damping and noise reduction structure described in this application 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, which can effectively absorb and disperse sound waves, reduce resonance and standing waves in the sound cavity, thereby improving sound quality and clarity.
[0036] The wearable electronic device with vibration damping and noise reduction structure described in this application can optimize the acoustic cavity volume of the electronic device. In wearable electronic devices such as glasses and headphones, where space is limited, the flexible sound-absorbing sheet 30 with a porous structure can achieve the effect of virtually enlarging the acoustic cavity without increasing the actual physical volume, thereby improving the loudness and low-frequency performance of the sound within a limited space.
[0037] The following section will provide a detailed description of the specific structure of each part of the wearable electronic device with shock absorption and noise reduction structure described in this application, as well as the position and connection relationship between each part.
[0038] The electronic device described in this application has a housing 10, as shown in Figures 1 and 2. In this embodiment, the housing 10 includes an upper cover 11 and a lower cover 12 that interlock, and a receiving cavity is formed between the upper cover 11 and the lower cover 12. The receiving cavity is used to install various functional modules in the electronic device. In other embodiments of this application, the housing 10 of the electronic device may also adopt an integral structure, as long as the receiving cavity for installing various functional modules is formed within the housing 10.
[0039] A sound-generating unit 20 is installed inside the accommodating cavity. The sound-generating unit 20 is usually a pre-packaged speaker module or a built-in speaker. In order to adapt to the shape of the housing 10 and at the same time minimize the size of the electronic device, the shape of the pre-packaged speaker module or the shape of the built-in speaker matches the shape of the accommodating cavity at the installation position.
[0040] The sound-emitting unit 20 is provided with a flexible sound-absorbing sheet 30. The flexible sound-absorbing sheet 30 has a porous structure and a certain degree of flexibility, allowing it to be bent appropriately. The flexible sound-absorbing sheet 30 covers the outer periphery of the sound-emitting unit 20 (speaker module or built-in speaker box) to cover at least part of the outer wall of the sound-emitting unit 20; the flexibility of the flexible sound-absorbing sheet 30 allows it to be bent and effectively cover the sound-emitting unit 20.
[0041] Preferably, the flexible sound-absorbing sheet 30 covers as much of the outer wall of the sound-generating unit 20 as possible, leaving only the necessary parts of the sound-generating unit 20 exposed (such as the sound hole 21, the mounting base, etc.).
[0042] Furthermore, the flexible sound-absorbing sheet 30 is fixed to the outer wall of the speaker module or the built-in speaker enclosure by adhesive bonding. In other embodiments of this application, the flexible sound-absorbing sheet 30 may also be fixed by other methods, such as by micro-screws.
[0043] Furthermore, as shown in Figures 1 and 2, the sound-generating unit 20 (speaker module or built-in speaker) has a sound-emitting hole 21, and the housing 10 has a sound-exiting hole 13 opposite to the sound-emitting hole 21. The sound generated by the vibration of the sound-generating unit 20 can be transmitted into the wearer's ear through the sound-emitting hole 21 and the sound-exiting hole 13.
[0044] The following will further explain the structure and technical effects of the preferred embodiment of the wearable electronic device with shock absorption and noise reduction structure described in this application.
