Description

Technical Field

[0001] This utility model belongs to the field of microphone technology, specifically relating to a microphone that can be worn in multiple scenarios. Background Technology

[0002] A microphone is an energy conversion device that converts sound signals into electrical signals. Its working principle involves the human voice passing through the air, causing a diaphragm to vibrate. The electromagnetic coil windings on the diaphragm and the magnet surrounding the moving microphone head create a magnetic field that cuts through the diaphragm, generating a weak, fluctuating current. This current is then transmitted to the amplifier, where the fluctuating current is converted back into sound in the reverse process.

[0003] In current technology, wired microphones are commonly used for presentations in classrooms and conference rooms. However, due to the presence of wires, wearing a wired microphone for extended periods can cause a feeling of pressure and discomfort, reducing user comfort. Therefore, some users have opted for wireless microphones. However, existing wireless microphones offer only one wearing method, making it impossible to switch between different usage scenarios. Prolonged use can easily cause fatigue in the wearing area, thus affecting the natural flow of the presentation. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this utility model, not all embodiments.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0043] Example 1:

[0044] Please see the appendix Figure 1 -Appendix Figure 2 The present invention provides a microphone suitable for multiple scenarios, including a sound transmission mechanism 1 and a wearing mechanism 2. The sound transmission mechanism 1 includes a sound transmission component 11 and a connecting component 12, and the sound transmission component 11 is connected to the connecting component 12. The wearing mechanism 2 includes a first wearing component 21 and a second wearing component 22, which are independently set, and the first wearing component 21 or the second wearing component 22 is magnetically connected to the connecting component 12.

[0045] The sound transmission component 11 includes a flexible tube 111 and a microphone capsule assembly 112. The flexible tube 111 connects the microphone capsule assembly 112 and the connecting component 12. The flexible tube 111 provides flexible support for the microphone, which not only facilitates the adjustment of the position of the microphone capsule assembly 112, but also ensures the positional stability of the microphone capsule assembly 112, thereby ensuring better sound pickup.

[0046] In this embodiment, the microphone can be magnetically connected to the first wearing component 21, depending on the usage scenario or wearing habits, to achieve a headband or neckband wearing method; it can also be magnetically connected to the second wearing component 22, to achieve a lapel clip wearing method; or it can be directly held by hand for speaking, thereby increasing the diversity of wearing methods, allowing users to choose the wearing method according to their habits, and users can also switch the wearing method in different usage scenarios, which not only improves the fit of the speech in the scenario and ensures the naturalness and smoothness of the speech, but also improves the wearing flexibility and meets the personalized needs of users in different environments.

[0047] In addition, users can avoid using the microphone in the same way for a long time, which can cause fatigue in the wearing area, thus effectively improving wearing comfort.

[0048] This microphone design facilitates disassembly and assembly, making the microphone easy to store and carry, thus improving the convenience of microphone storage and management. Furthermore, the simple overall structure reduces the number of devices required for carrying and use, significantly simplifying the configuration of the audio system.

[0049] Furthermore, compared to wired microphones, the wireless design of the microphone in this embodiment provides a wider range of motion, allowing users to move freely in various situations without being restricted by cables. Moreover, the microphone structure provided by this invention is simple and elegant, effectively improving the microphone's aesthetics and enhancing the professional feel of the usage environment.

[0050] Example 2:

[0051] The difference between this embodiment and Embodiment 1 lies in the specific structural description of the magnetic connection between the sound transmission mechanism 1 and the first wearing component 21. Please refer to... Figure 3 The connecting component 12 includes an outer component 121 and a first magnetic attraction component 122, with the outer component 121 enclosing and connecting to the first magnetic attraction component 122. This provides a certain level of protection for the first magnetic attraction component 122, preventing it from being affected by external factors and thus ensuring its magnetic attraction performance.

[0052] In some embodiments, see Figure 4 The first wearing component 21 includes a connecting bow 211, a second magnetic component 212, and fixing components 213 respectively connected to both ends of the connecting bow 211. At least one fixing component 213 wraps around the second magnetic component 212. The first magnetic component 122 and the second magnetic component 212 attract each other so that the fixing component 213 is attached to the outer component 121.

[0053] Preferably, the fixing component 213 can be made of silicone, which can provide a comfortable wearing experience, reduce discomfort during long-term use, and effectively improve user comfort.

[0054] With the structural design of the first wearing component 21, the wearing method can be either headband-style or neckband-style. When the wearing method is headband-style, the connecting bow 211 is placed on the head, the fixing components 213 at both ends are attached to the position close to the user's ears, the connecting component 12 and the fixing components 213 are magnetically connected to each other, and the sound transmission component 11 is placed close to the user's mouth to ensure sound pickup effect.

[0055] When worn as a neckband, the connecting bow 211 is placed around the neck, and the fixing components 213 at both ends are placed on the front of the user's shoulders. The connecting component 12 and the fixing component 213 are magnetically connected to each other, and the sound transmission component 11 is placed close to the user's mouth, that is, the flexible tube 111 points upward from the front of the shoulder to the mouth position, thereby ensuring the sound pickup effect.

[0056] In this embodiment, the first wearing component 21 utilizes a magnetic attraction principle to adjust the angle between the sound transmission mechanism 1 and the first wearing component 21, thereby flexibly switching between headband and neckband wearing modes and increasing the versatility of wearing methods. This structure facilitates quick switching between wearing modes for the user, making operation simple and easy.

[0057] Please see Figure 4 The second magnetic attraction component 212 includes a second magnet 2121 and a second magnetic shell 2122. The second magnetic shell 2122 is provided with a second magnetic groove 2123 corresponding to the second magnet, and the second magnet 2121 is embedded in the second magnetic groove 2123. Through this arrangement, the second magnet 2121 is restricted and positioned by the second magnetic groove 2123 in the second magnetic shell 2122, which can effectively ensure the stability of the second magnet 2121, thereby ensuring that the magnetic attraction area does not change, ensuring the attraction stability of the second magnetic attraction component 212 and the first magnetic attraction component 122, avoiding the phenomenon of detachment between the sound transmission mechanism 1 and the wearing mechanism 2, and effectively ensuring the connection stability between the first wearing component 21 and the sound transmission mechanism 1.

[0058] Please see Figures 5-7 A positioning groove 1211 is provided on the side of the peripheral component 121 that is in contact with the fixing component 213. The fixing component 213, which is in contact with the peripheral component 121, is provided with a first positioning block 2131 corresponding to the positioning groove 1211. The first positioning block 2131 is embedded in the positioning groove 1211. In this way, while the sound transmission mechanism 1 and the first wearing component 21 are magnetically connected to each other, the first positioning block 2131 in the fixing component 213 is embedded in the positioning groove 1211 of the peripheral component 121. This can effectively prevent the peripheral component 121 and the fixing component 213 from slipping due to shaking, limit the peripheral component 121 and the fixing component 213, ensure their adsorption force, and improve the connection stability of the two.

[0059] Please see Figures 8-9The first magnetic attraction component 122 includes a first magnet 1221 and a first magnetic shell 1222. The first magnetic shell 1222 is provided with a first magnetic groove 1223 corresponding to the first magnet, and the first magnet is embedded in the first magnetic groove 1223. This arrangement, by embedding the first magnet 1221 in the first magnetic groove 1223, prevents the first magnet 1221 from shaking within the outer component 121 when the sound transmission mechanism 1 operates, thus avoiding changes in the adsorption surface. It effectively limits the position of the first magnet 1221, ensuring a stable adsorption force. Furthermore, this structure, which limits the position of the first magnet 1221, is simple to design and easy to manufacture. It also facilitates quick replacement and maintenance when the first magnet 1221 needs to be replaced or maintained, improving operational convenience.

[0060] The peripheral component 121 includes a first housing 1212 and a second housing 1213. The first housing 1212 and the second housing 1213 are connected and form a receiving cavity. The first magnetic component 122 is embedded in the receiving cavity. By setting the first housing 1212 and the second housing 1213, it is convenient to inspect and maintain the first magnetic component 122 placed in the receiving cavity in the later stage, and improve the convenience of subsequent maintenance.

[0061] The first housing 1212 has a first surface 1214 and a second surface 1215 disposed opposite to each other. The first surface 1214 is magnetically connected to the wearing mechanism 2, and the second surface 1215 is connected to the first magnetic component 122. The positioning groove 1211 is formed by the first surface 1214 being recessed towards the second surface 1215, and the second surface 1215 protruding towards the first magnetic component 122 to form a limiting block 1216. The first magnetic shell 1222 is provided with a limiting groove 1225 corresponding to the limiting block 1216. By setting the limiting groove 1225 and the limiting block 1216 to be embedded and positioned, the first housing 1212 and the first magnetic component 122 are limited and fixed, thereby further fixing the first magnetic component 122, ensuring the stability of the first magnetic component 122 in the receiving cavity, and ensuring the smooth use of the microphone.

[0062] Example 3:

[0063] The difference between this embodiment and Embodiment 2 is that the sound transmission mechanism 1 and the second wearing component 22 are magnetically connected to each other. Please refer to... Figure 10 In this embodiment, the second wearing component 22 includes a first clamp 221, a second clamp 222, and a third magnetic component 223. The first clamp 221 and the second clamp 222 are elastically hinged together, and the third magnetic component 223 is connected to the first clamp 221 and disposed between the first clamp 221 and the second clamp 222. The third magnetic component 223 and the second magnetic component 222 attract each other so that the first clamp 221 is attached to the peripheral component 121.

[0064] In this embodiment, the microphone is worn in a clip-on manner, where the first clip 221 and the second clip 222 work together to form a clip that can be attached to the user's collar or upper body. Through the third magnetic component 223, the sound transmission mechanism 1 and the second wearing part 22 can be directly magnetically connected. During the switching of wearing modes, the sound transmission mechanism 1 can be directly removed from the first wearing part 21 and attached to the second wearing part 22 for magnetic connection. The overall switching process is simple, quick, and effortless. This allows for switching between wearing modes in different usage scenarios, improving wearing flexibility and meeting the personalized needs of users in different environments.

[0065] In some embodiments, see Figure 11 The outer component 121 has a positioning groove 1211 on the side that is in contact with the first clamp 221. The first clamp 221 has a second positioning block 2211 corresponding to the positioning groove 1211, and the second positioning block 2211 is embedded in the positioning groove 1211. In this way, the second positioning block 2211 of the first clamp 221 is embedded in the positioning groove 1211 of the outer component 121, which can effectively ensure the stable positioning of the second wearing part 22 and the sound transmission mechanism 1, avoid the phenomenon of falling off due to shaking, and ensure the stable adsorption force between the two.

[0066] In some embodiments, see Figure 12 The third magnetic attraction component 223 includes a third magnet 2231 and a fixing plate 2232. The first clamping member 221 has a third magnetic groove 2212 corresponding to the third magnet 2231, in which the third magnet 2231 is embedded. The fixing plate 2232 covers the third magnet 2231 and is connected to the first clamping member 221. This arrangement allows the third magnet 2231 to be embedded in the third magnetic groove 2212, resulting in a smaller thickness between the third magnet 2231 and the connecting member 12, thereby strengthening the magnetic attraction between them and ensuring a tight connection. Furthermore, the fixing plate 2232 ensures the flatness of the first clamping member 221, thus ensuring stable clamping between the first clamping member 221 and the second clamping member 222. This structure is simple and compact, and also facilitates subsequent maintenance and replacement of the third magnet 2231.
