[0022] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0023] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The following further details a sound insulation mask of the present invention with reference to the accompanying drawings.

[0025] Combined with the attached Figure 1-6 , the present invention is introduced in detail.

[0026] A sound insulation mask includes a mask body, on which a detachable pick-up 1, a communication module 2 and a headphone 3 are provided. The mask body has a unique structure and is sequentially stacked with an inner layer 4, a middle layer 5 and an outer layer 6 from the inside to the outside. Each layer is designed with ventilation holes 7, and the ventilation holes 7 between adjacent layers are arranged in a staggered manner to reduce the direct penetration of sound and enhance the sound insulation effect. The inner surface of the inner layer 4 and between adjacent layers are filled with sound-absorbing materials to further improve the sound insulation effect.

[0027] Through the design of the staggered ventilation holes 7 in the inner layer 4, middle layer 5 and outer layer 6 of the mask body, the sound transmission path is effectively blocked. The inner layer 4 directly contacts the face, uses a soft material and covers the sound-absorbing material to improve the wearing comfort and the sound insulation effect. The middle layer 5 and the outer layer 6 respectively play the roles of further sound insulation and enhancing the structural strength.

[0028] Among them, the inner layer 4, the middle layer 5 and the outer layer 6 are all referring names, indicating that the layered structure of the mask can be summarized into these three parts. Each part can be a single-layer structure or a multi-layer stack. If each part is a single-layer structure, the overall structure is similar to or the same as the structural schematic diagram of this application; if some of the layers are expanded into multi-layer structures, for example, the middle layer 5 can be a stack of several thin layers, the structure of the thin layers should also be that the ventilation holes 7 between adjacent thin layers are arranged in a staggered manner. Therefore, it should be noted that as long as the ventilation holes 7 are arranged in a staggered manner and the structure of the mask layers belongs to the concept of the present invention, it should be within the protection scope of this application.

[0029] Fixed wings 8 that fit the face are provided on both left and right sides of the mask body to ensure the mask is worn stably and reduce air leakage. A nose mask 9 that fits the nose is added at the upper end of the mask body, which can not only effectively block the leakage of sound from above, but also prevent the exhaled air from directly blowing on the lens, and is suitable for people wearing glasses.

[0030] The ventilation holes 7 of the inner layer 4 are specifically set at the mouth and nose positions for easy breathing. The ventilation holes 7 of the middle layer 5 are located above the ventilation holes 7 of the inner layer 4, and the ventilation holes 7 of the outer layer 6 correspond to those of the inner layer 4 at the mouth and nose positions but are offset. This design not only ensures breathability but also optimizes the sound insulation effect.

[0031] The inner layer 4 is made of silica gel material, and its softness and sealing performance enhance the wearing comfort. The outer layer 6 is made of plastic or rubber with toughness to enhance durability and the ability to resist external impacts.

[0032] The sound-absorbing material filled on the inner surface of the inner layer 4 and between adjacent two layers is preferably sound-absorbing cotton, which has good sound-absorbing performance and can effectively absorb and reduce sound energy to reduce outward transmission.

[0033] The integrated communication module 2 supports wireless communication modules 2 (such as Bluetooth, Wi-Fi) and / or wired communication modules 2, facilitating users to select communication methods according to needs and realizing functions such as voice calls or receiving instructions.

[0034] The mask is built-in with a modular battery and a charging interface to provide power support for the pickup 1, communication module 2, and earphone 3, ensuring long-term use.

[0035] The specific implementation process of a sound-insulating mask of the present invention is as follows:

[0036] The sound-insulating mask consists of the following parts:

[0037] (1) Sound-blocking wearing structure components: including a structural design for comfortable face wearing, a labyrinth sound-insulating structural design, an electronic module card slot structural design, signal line and power supply line designs, etc. The wearing structure is composed of multiple materials: soft silica gel is used at the part in contact with the face; the mask shell is made of plastic or rubber with a certain degree of toughness; sound-absorbing cotton is filled in the gaps of the labyrinth sound-insulating structure inside the mask.

[0038] In the facial area below the nose tip of the mask, a labyrinth-style multi-layer structure is designed. Each layer of the multi-layer structure is designed with ventilation holes 7, and the ventilation holes 7 of adjacent two layers are respectively designed at non-corresponding upper and lower positions to increase the air transmission distance. The ventilation holes 7 of each layer adopt different shapes. The ventilation holes 7 of the middle layer adopt the shape of ventilation holes 7 combined with multiple small holes of different diameters. This design is to block the sound propagation in different frequency ranges. Sound-absorbing materials such as sound-absorbing cotton are pasted between the inner layer 4 close to the face and adjacent two layers to reduce echo between the face and the mask, and the sound-absorbing cotton between the two layers plays a role in absorbing sound.

[0039] The outermost layer 6 of the mask is also designed with ventilation holes 7. This design is to maintain air circulation so that the wearer can breathe normally. The sound transmitted from these ventilation holes 7 will have its sound intensity greatly reduced due to multiple layers of obstruction and absorption.

[0040] (2) Electronic supporting module: including a pickup 1, wired and wireless sound transmission modules, a headset 3 worn by the user, etc. The wired and wireless modules can be interchanged, that is, the working states of wired communication and wireless communication of this sound insulation mask are hard-switched by the disassembly and installation of the modules.

[0041] (3) Power supply module 10: including a modular battery pack (lithium battery), supporting charging equipment, etc. These devices are selected according to the application scenarios, and their installation positions are designed according to the device model selection and actual application requirements.

[0042] The application scenarios of the present invention are as follows:

[0043] (1) For use in wired meetings and wireless meetings

[0044] When the wired module is adopted, its application scenario is to replace the existing wired microphone. When the wireless transmission and reception modules are equipped, it replaces the wireless microphones used in the existing conference system.

[0045] (2) Personal use scenarios

[0046] When the electronic supporting module is replaced by a Bluetooth communication module, the present invention can be connected to external devices via Bluetooth and can be used on mobile devices such as mobile phones.

[0047] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
