Technical Field

[0001] The utility model belongs to the technical field of microphones, and in particular relates to a microphone device with ultraviolet disinfection and sterilization functions. Background Art

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. It can be used to capture sound waves and convert them into corresponding electrical signals, which can be further processed or transmitted by recording equipment, sound amplification systems, communication equipment, etc.

[0003] The microphone mainly consists of a pickup component and a mesh structure. The pickup component is responsible for converting sound waves into electrical signals. The mesh structure is usually located on the outside of the pickup component to protect the pickup component from physical damage while allowing sound to pass through and using the mesh pores to reduce wind noise and explosive sounds.

[0004] When using a microphone, the user's hands will frequently touch the microphone's mesh cover. At the same time, a large amount of saliva droplets will be produced when the human mouth speaks. Especially in public places such as KTVs, lecture halls, conference centers, and recording studios, microphones are often shared by multiple people. As a result, a variety of microorganisms may accumulate on the surface of the microphone, including bacteria (such as Escherichia coli, Staphylococcus aureus), fungi (such as Aspergillus fumigatus), viruses, and other pathogens. If shared microphones are not cleaned and disinfected in time, they can easily become a medium for spreading diseases.

[0005] However, under the existing technology, conventional microphone products themselves do not have the function of autonomous disinfection and sterilization. If they are disinfected and sterilized manually, the internal structure of the microphone product is relatively complex, and it is impossible to achieve thorough cleaning and disinfection, and the disinfection efficiency is low. Some microphone products with certain disinfection functions also have the disadvantages of poor disinfection effect, low degree of intelligence, and inconvenience in use. Utility Model Content

[0010] The control circuit is electrically connected to the LED light board, and the control circuit includes a detection module and a main control module. The control circuit is configured such that when the detection module detects that the microphone is in use, the main control module controls the ultraviolet LED lamp to turn off, and when the detection module detects that the microphone is in an inactive state, the main control module controls the ultraviolet LED lamp to turn on.

[0011] Preferably, the axial side wall of the pickup assembly is provided with a light-guiding inclined surface at the top of the transparent base, and the light-guiding inclined surface is used to limit the scattering path of the ultraviolet light transmitted through the transparent base.

[0026] The microphone device with ultraviolet disinfection and sterilization function proposed by the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the utility model will become clearer according to the following description and claims.

[0027] See also Figures 1 to 3 This embodiment provides a microphone device with ultraviolet disinfection and sterilization function, which is used to realize the autonomous disinfection and cleaning function of the microphone product and improve the hygiene and safety of the microphone product.

[0028] The microphone device described in this embodiment structurally includes a microphone body and a mesh cover 1. The microphone body further includes a sound pickup assembly 2 and a handle portion 3. The sound pickup assembly 2 is arranged on the top of the handle portion 3. The sound pickup assembly 2 is mainly used to receive sound waves and convert the sound waves into electrical signals. The mesh cover 1 is a cover structure with a plurality of pores, which is sleeved on the outside of the sound pickup assembly 2 to provide physical protection for the sound pickup assembly 2, allow sound to pass through the pores, and reduce wind noise and plosive sounds.

[0029] The mesh cover 1 is assembled with the microphone body so that the mesh cover 1 is fixed on the top of the microphone body, and the inner side of the mesh cover 1 cooperates with the top surface of the microphone body to form a receiving space for placing the sound pickup component 2. Since a number of holes are provided on the side and top surface of the mesh cover 1, during the use of the microphone, saliva droplets sprayed by the human body are easily accumulated in the holes and are not easy to clean, which may cause the risk of bacterial transmission.

[0030] Therefore, in this embodiment, the structure of the microphone is improved so that it has an ultraviolet disinfection and cleaning function. Taking the microphone device with the mesh cover 1 placed vertically upward as an example, specifically, a transparent base 4 is vertically arranged on the bottom periphery of the sound pickup component 2, and a horizontally arranged LED light board 5 is provided at the bottom of the transparent base 4. A circular array light group formed by a plurality of ultraviolet LED lamps 6 is provided on the LED light board 5, wherein the circular array light group formed by the plurality of ultraviolet LED lamps 6 is arranged opposite to the vertical side wall of the transparent base 4, that is, the ultraviolet LED lamp 6 is directly opposite to the bottom of the vertical side wall of the transparent base 4. When the ultraviolet LED lamp 6 emits ultraviolet light, the ultraviolet light can be transmitted along the extension direction of the side wall of the transparent base 4 to realize light beam propagation.

[0031] A light guide 7 is also sleeved on the outside of the vertical arrangement direction of the transparent base 4 and the LED light board 5. The light guide 7 is a cylindrical structure and is used to limit and guide the propagation path of the light beam. Among them, the radial size of the pickup component 2 will change with the extension of the height. The radial size of the shaft body of the pickup component 2 located in the transparent base 4 is a first length, and the radial size of the shaft body of the top of the pickup component 2 not located in the transparent base 4 is a second length. The first length is smaller than the second length, so that the side wall of the pickup component 2 will form a light guide slope 8 at the top of the transparent base 4. When the microphone device is performing ultraviolet disinfection and sterilization operations, the several ultraviolet LED lamps 6 on the LED light board 5 emit ultraviolet light, and the ultraviolet light is transmitted along the side wall of the transparent base 4. Due to the sleeves on the outside of the transparent base 4 and the LED light board 5, the ultraviolet light is transmitted along the side wall of the transparent base 4. There is an opaque light guide 7, so the ultraviolet light can only propagate from bottom to top along the side wall of the transparent base 4, and a gap is formed between the top of the light guide 7 and the side wall of the pickup assembly 2. The top portion of the transparent base 4 extends out of the top upper edge of the light guide 7, so that the ultraviolet light transmitted into the transparent base 4 propagates to the top of the transparent base 4 and is further scattered from the gap. At the same time, due to the arrangement of the light guide 7 and the light guiding inclined surface 8, the scattered ultraviolet light has an upwardly offset inclination angle as a whole, which is directly opposite to the pore area on the inner side of the mesh cover 1, thereby realizing the precise propagation of the ultraviolet light and achieving the disinfection and sterilization function of the ultraviolet light.

[0032] Furthermore, the microphone device with ultraviolet disinfection and sterilization function provided in this embodiment also includes a control circuit, which is electrically connected to the LED light board 5, wherein the control circuit includes a detection module and a main control module, and the detection module is provided with a photosensitive sensor, which detects whether there are people or obstacles around the microphone device in real time based on the photoelectric effect. Here, it is defined that the microphone product will be uniformly stored when not in use, and there is no obstruction around the microphone product when in the storage state, that is, if the detection module detects that there is an obstruction around the microphone, it is determined that the microphone product is still in use. At this time, the main control module uses a switch to turn off the ultraviolet LED lamp 6 to prevent the long-term irradiation of the ultraviolet LED lamp 6 from causing harm to the human body. If the detection module does not detect the existence of an obstruction around the microphone within a certain detection time, it is determined that the microphone product is in an inactive state and the surrounding environment is relatively safe. At this time, the main control module uses a switch to turn on the ultraviolet LED lamp 6 to disinfect and sterilize the mesh cover 1 of the microphone product. Among them, regarding the determination of the use state and inactive state of the microphone product, it can also be further combined with the switch state of the microphone product, the dynamic and static object recognition information, etc., to realize a more accurate and intelligent detection and determination function of the detection module.

[0033] In summary, this embodiment provides a microphone device with ultraviolet disinfection and sterilization function. An ultraviolet LED lamp 6 is arranged inside the microphone device mesh cover 1, and a transparent base 4 and a light guide 7 are arranged on the pickup component 2 to form a light guide channel, so that the ultraviolet light emitted by the ultraviolet LED lamp 6 propagates along the set light guide channel and finally irradiates the pore area of ​​the mask. Through the light beam guidance, the ultraviolet light propagation path is controllable, and the irradiation intensity and accuracy are better, so as to achieve efficient and safe ultraviolet light disinfection and cleaning functions. Furthermore, this embodiment also includes an intelligent control circuit, which can automatically turn on or off the ultraviolet LED lamp 6 according to the use status of the microphone. On the one hand, the disinfection and cleaning operation of the microphone product is automated, reducing labor costs and improving cleaning efficiency. On the other hand, the intelligent control circuit can detect in real time whether there is a user around the microphone product to prevent ultraviolet rays from causing harm to the human body, so that this embodiment is safer during use.

[0034] Preferably, reflective materials are coated on the inner wall surface of the mesh cover 1 and the outer peripheral wall surface of the top of the sound pickup assembly 2, respectively, to improve the propagation path of the ultraviolet light in the accommodating space. Since the ultraviolet light scattered by the transparent base 4 in this embodiment has an upwardly offset inclination angle as a whole, the reflective materials on the inner wall of the mesh cover 1 and the outer wall of the sound pickup assembly 2 are further utilized, so that the ultraviolet light can be reflected multiple times along the gap between the inner wall of the mesh cover 1 and the outer wall of the sound pickup assembly 2, so that the pores on the side and top of the mesh cover 1 can be fully irradiated by the ultraviolet light, thereby achieving the effect of thorough disinfection and cleaning.

[0035] Preferably, the number of ultraviolet LED lamps 6 is 4 to 8, which are evenly distributed circumferentially on the LED light board 5. When the LED light board 5 is powered on, the annular array lamp group together outputs ultraviolet light with a wavelength limited to 254nm, thereby improving the intensity and uniformity of the ultraviolet light inside the microphone product.

[0036] Preferably, an internal thread is provided on the inner edge of the bottom opening of the mesh cover 1, and an external thread matching the internal thread of the mesh cover 1 is provided at a relative position on the outer periphery of the handle portion 3. During the assembly process of the microphone device, the mesh cover 1 is sleeved on the top of the microphone body, and the mesh cover 1 and the microphone body are detachably connected through threaded cooperation, which facilitates the subsequent disassembly and maintenance of the microphone product.

[0037] Preferably, an independent battery is provided in the microphone body, and the independent battery is used to power the sound pickup component 2 and the LED light board 5. At the same time, the control circuit also includes a power management module, and the power management module is used to control the independent battery to power the LED light board 5 independently to ensure the continuity and stability of the ultraviolet disinfection and sterilization operation. The microphone body is provided with a type C interface, which can be used to charge the independent battery and realize data connection between the main control module and the external device.

[0038] Preferably, the frequency and duration of turning on the ultraviolet LED light 6 can be set according to actual conditions. In this embodiment, it is limited that when the microphone product is in a charging state and there is no user around the microphone product, the ultraviolet LED light 6 is turned on, and the single turning-on time is 30 minutes. In addition, it can also be set that the ultraviolet LED light is turned on after the microphone product is turned off and there is no user around the microphone product.

[0039] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the protection scope of the present invention.
