Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a wireless microphone. Background Technology

[0002] Wireless microphones, as a commonly used audio acquisition device, are widely used in various occasions, such as stage performances, conference speeches, and teaching. Their basic working principle is to convert sound signals into electrical signals through a pickup module, and then wirelessly transmit the signals to receiving devices (speakers, etc.) for amplification and playback via a transmission module.

[0003] However, in noisy environments, the sound pickup quality of wireless microphones is often affected by ambient noise. A new type of wireless microphone utilizes a control module to filter the sound signal acquired by the pickup head, eliminating background noise and thus achieving noise reduction.

[0004] However, due to the limited clarity and completeness of the sound captured by the microphone, the control module has difficulty distinguishing noise signals, resulting in poor noise reduction performance of the wireless microphone. Utility Model Content

[0054] This utility model proposes a wireless microphone.

[0056] In one embodiment of this utility model, the wireless microphone includes:

[0057] The cylindrical body assembly 100 is provided with a first receiving cavity 101;

[0058] The mesh head assembly 200 is threadedly connected to one end of the cylinder assembly 100 and is provided with a second receiving cavity;

[0059] The pickup module 300 includes a mounting plate 310 and multiple pickup heads 320. The mounting plate 310 is fixed inside the second receiving cavity and perpendicular to the axis of the cylinder assembly 100. The multiple pickup heads 320 are arranged in a ring array and fixed to the mounting plate 310. The pickup heads 320 are used to collect sound signals and convert the sound signals into electrical signals.

[0060] The control module 400 is fixed inside the first receiving cavity 101. Each pickup head 320 is electrically connected to the pickup module 300 via a wire. The control module 400 is used to receive electrical signals and filter out target signals.

[0061] The transmission module 500 is fixed inside the first receiving cavity 101 and is electrically connected to the control module 400 via wires. The transmission module 500 is used to receive the target signal and transmit the target signal to the receiving device.

[0062] The wireless microphone in this invention includes a microphone body assembly 100, a mesh head assembly 200, a pickup module 300, a control module 400, and a transmission module 500. The pickup module 300 is installed inside the mesh head assembly 200 and includes a mounting plate 310 and multiple pickup heads 320. The mounting plate 310 is used to fix the pickup heads 320. The pickup heads 320 are used to collect sound signals and convert them into electrical signals. The control module 400 is installed inside the microphone body assembly 100 and is responsible for processing the electrical signals transmitted from the pickup module 300. The control module 400 identifies and filters the target signal (e.g., the user's voice) from the electrical signals transmitted from the multiple pickup heads 320, and filters out noise signals (e.g., ambient noise, music, etc.) to achieve noise reduction and reduce noise interference. The transmission module 500 is responsible for wirelessly transmitting the target signal processed by the control module 400 to a receiving device (e.g., a speaker or recording device). In this scheme, multiple microphone heads 320 are arranged in a ring around a central point. Compared with a wireless microphone with a single microphone head 320, the microphone module 300 can capture sound from all directions more comprehensively, reduce sound loss, and thus improve the clarity and integrity of the collected sound. This, in turn, helps the control module 400 to identify and filter target signals and noise signals, thereby improving the noise reduction effect of the wireless microphone.

[0063] The control module 400 adopts existing technology in its specific structure and algorithm. Specifically, the control module 400 includes components such as a preamplifier, a filter, an analog-to-digital converter, and a microcontroller. Each pickup head 320 is equipped with a corresponding preamplifier, which is used to amplify the electrical signal output by the pickup head 320. The filter is used to filter out ultra-low frequency or high frequency noise that the pickup head 320 may pick up. The electrical signal output by the pickup head 320 is an analog signal. The analog-to-digital converter is used to convert the analog signal into a digital signal for processing by the microcontroller. The microcontroller uses an algorithm to filter and reduce noise in the digital signal.

[0064] In one embodiment, the head assembly 200 includes:

[0065] The lower housing 210 is located at one end of the cylinder assembly 100, and the mounting plate 310 is fixed to the lower housing 210.

[0066] The upper housing 220 is mesh-like and fastens to the lower housing 210. The upper housing 220 and the lower housing 210 together enclose and form a second receiving cavity.

[0067] Windshield 230, fitted to the inner wall of upper housing 220; and

[0068] The shielding mesh 240 is attached to the side of the windproof cover 230 that is away from the inner wall of the upper housing 220.

[0069] Reference Figure 1, Figure 2 as well as Figure 4 In this embodiment of the invention, the mesh head assembly 200 includes a lower housing 210, an upper housing 220, a windproof cover 230, and a shielding mesh 240. The lower housing 210 is connected to the end of the cylinder assembly 100, providing structural support for the entire mesh head assembly 200. The upper housing 220 is made of metal or plastic and has a mesh-like structure to facilitate the passage of sound waves. The upper housing 220 is fastened to the lower housing 210 and together with the lower housing 210, they form a second receiving cavity. The structure is simple and facilitates the assembly of internal components of the mesh head assembly 200. The windproof cover 230 is attached to the inner side of the upper housing 220 and is made of porous materials such as foam or sponge. It can block airflow from directly impacting the microphone head 320, reducing wind noise caused by ambient wind and user exhalation, while having minimal impact on sound transmission, which helps to ensure the sound pickup effect of the microphone head 320. The shielding mesh 240 is attached to the inside of the windproof cover 230 and is made of conductive material, such as copper or aluminum. The shielding mesh 240 can reflect and absorb electromagnetic waves, thereby reducing the interference of external electromagnetic signals on the microphone head 320, improving the microphone head 320's sound pickup effect, reducing noise, and thus improving the noise reduction effect of the wireless microphone.

[0070] In one embodiment, the inner wall of the lower housing 210 is provided with a support column 211, and at least one support column 211 is provided between any two adjacent pickup heads 320. The mounting plate 310 is detachably connected to the support column 211.

[0071] Combination Figure 1 and Figure 3 In this embodiment of the invention, a support column 211 is provided on the inner wall of the lower housing 210 to support and fix the mounting plate 310. At least one support column 211 is provided between any two adjacent microphone heads 320 to ensure that each microphone head 320 is effectively supported, thereby improving the stability of each microphone head 320. This prevents the microphone heads 320 from loosening or being damaged due to vibration or impact, improving the reliability and durability of the wireless microphone, and also helps to reduce the problem of poor sound pickup quality caused by loose microphone heads 320. The mounting plate 310 and the support column 211 are detachably connected, which can be achieved by means of clips, screws, etc., making the disassembly, assembly, and maintenance of the entire microphone module 300 more convenient.

[0072] Specifically, in this embodiment, there are three microphone heads 320 arranged in a ring at equal intervals. There are also three support columns 211, with each support column 211 located between two microphone heads 320, ensuring the stability of the mounting plate 310 and each microphone head 320.

[0073] In one embodiment, the pickup module 300 further includes a first damping pad 330 disposed between the pickup head 320 and the mounting plate 310; and / or,

[0074] The pickup module 300 also includes a second damping pad (not shown in the figure), which is located between the mounting plate 310 and the support column 211.

[0075] Reference Figure 3 In an embodiment of this utility model, a first damping pad 330 is provided between the microphone head 320 and the mounting plate 310. The first damping pad 330 is made of an elastic material, such as rubber or sponge. The first damping pad 330 can absorb and isolate the vibration of the microphone head 320, prevent the microphone head 320 from driving the mounting plate 310 to vibrate and cause the mounting plate 310 to emit noise, thereby reducing the noise and interference around the microphone head 320, improving the sound pickup quality, and thus improving the noise reduction effect of the wireless microphone.

[0076] In an embodiment of this utility model, a second vibration damping pad is provided between the mounting plate 310 and the support column 211. The second vibration damping pad is made of an elastic material, such as rubber or sponge. The second vibration damping pad can absorb and isolate external vibrations, reduce the vibration of the mesh head assembly 200 transmitted to the mounting plate 310 through the support column 211, and further reduce the external vibrations transmitted to the microphone head 320, thereby reducing noise and interference around the microphone head 320, improving the sound pickup quality, and thus improving the noise reduction effect of the wireless microphone.

[0077] In one embodiment, the mounting plate 310 is provided with a first weight reduction hole 311 and a plurality of second weight reduction holes 312. The first weight reduction hole 311 is located at the center of the mounting plate 310, and the plurality of second weight reduction holes 312 are arranged around the first weight reduction hole 311. At least one second weight reduction hole 312 is provided between any two adjacent pickup heads 320.

[0078] Reference Figure 3 In this embodiment of the invention, the mounting plate 310 is provided with a first weight-reducing hole 311 and a plurality of second weight-reducing holes 312. The weight-reducing holes reduce the weight of the mounting plate 310, thereby reducing the overall weight of the wireless microphone and improving its portability. The plurality of second weight-reducing holes 312 are arranged around the first weight-reducing hole 311, and at least one second weight-reducing hole 312 is provided between two adjacent pickup heads 320. This helps to improve the uniformity of the strength and rigidity of the mounting plate 310 and extend its service life.

[0079] In one embodiment, the first receiving cavity 101 includes a first sub-cavity 1011 and a second sub-cavity 1012, the second sub-cavity 1012 is arranged around the outside of the first sub-cavity 1011, the control module 400 is disposed inside the first sub-cavity 1011, and the transmission module 500 includes:

[0080] The wireless transmitter 510 is fixed inside the first sub-cavity 1011 and electrically connected to the control module 400; and

[0081] Antenna 520 is located inside the second sub-cavity 1012 and is electrically connected to wireless transmitter 510. Wireless transmitter 510 receives target signals and transmits the target signals to receiving devices through antenna 520.

[0082] Combination Figure 1 and Figure 5 In this embodiment of the invention, the transmission module 500 includes a wireless transmitter 510 and an antenna 520. The wireless transmitter 510 receives the target signal from the control module 400 and transmits the target signal through the antenna 520 to the receiving device. The first receiving cavity 101 of the body assembly 100 includes a first sub-cavity 1011 and a second sub-cavity 1012. The second sub-cavity 1012 is arranged around the outside of the first sub-cavity 1011. The wireless transmitter 510 of the transmission module 500 and the control module 400 are located inside the first sub-cavity 1011, and the antenna 520 of the transmission module 500 is separately arranged inside the second sub-cavity 1012. This reduces the interference of the antenna 520 to the control module 400 and the wireless transmitter 510, improves the reliability of the control module 400 and the wireless transmitter 510, and extends the service life of the wireless microphone. Specifically, the wireless transmitter 510 can be a Bluetooth module, a WiFi module, an FM transmitter, etc., and the control module 400 can be a microprocessor, a digital signal processor, etc.

[0084] The cylindrical body 110 has a first sub-cavity 1011, and the mesh head assembly 200 is located at one end of the cylindrical body 110; and

[0085] The cover 120 is fitted over the end of the cylinder 110 near the mesh head assembly 200, and the outer wall of the cylinder 110 and the cover 120 together form the second sub-cavity 1012.

[0086] Among them, the end of the cylinder 110 near the head assembly 200 is also provided with a notch 111, which connects the first sub-cavity 1011 and the second sub-cavity 1012.

[0087] Reference Figures 5 to 7In an embodiment of this utility model, the cylindrical assembly 100 includes a cylindrical body 110 and a cover 120. The cylindrical body 110 has a first sub-cavity 1011, and the cover 120 is fitted over the outside of the cylindrical body 110, so that the outer wall of the cylindrical body 110 and the cover 120 surround and form a second sub-cavity 1012. The structure is simple and easy to manufacture, reducing the manufacturing difficulty of the second sub-cavity 1012. The end of the cylindrical body 110 near the mesh head assembly 200 has a notch 111 connecting the first sub-cavity 1011 and the second sub-cavity 1012, which facilitates the electrical connection between the antenna 520 in the second sub-cavity 1012 and the wireless transmitter 510 in the first sub-cavity 1011.

[0088] In one embodiment, the antenna 520 is at least partially spirally wound around the outside of the cylindrical body 110.

[0089] Reference Figure 7 In an embodiment of this utility model, at least a portion of the antenna 520 is designed in a spiral shape and is wound around the outside of the cylinder 110. The structure is compact and has strong anti-interference ability, which is beneficial to enhancing the stability of the signal transmitted from the wireless microphone to the receiving device.

The outer wall of the cylinder 110, the cover 120 and the limiting part 112 together surround and form the second sub-cavity 1012.

[0091] Reference Figure 5 and Figure 6 In this embodiment of the invention, the cover 120 is threadedly fitted over the outside of the cylinder 110, facilitating assembly. During assembly, the antenna 520 is first positioned outside the cylinder 110, then the cover 120 is fitted over the cylinder 110. The cover 120 is then screwed until it covers the limiting portion 112, thus forming the second sub-cavity 1012 and assembling the antenna 520 within it. One end of the cover 120 is threadedly connected to the outer wall of the cylinder 110, while the other end is fitted over the limiting portion 112, conveniently isolating the second sub-cavity 1012 from the external environment. This reduces the possibility of dust, liquids, etc., entering the second sub-cavity 1012 and extends the service life of the antenna 520.

[0092] Reference Figure 5 and Figure 6Specifically, in this embodiment, the lower housing 210 is fitted inside the cylinder 110 and threadedly connected to the cylinder 110.

When the lower housing 210 and the cylinder 110 are installed in place, the end stop 212 abuts against the end of the cover 120 near the mesh head assembly 200. The end stop 212 covers the threaded connection between the cover 120 and the cylinder 110, further reducing the possibility of dust, liquids, etc. from the external environment entering the second sub-cavity 1012, and also reducing the possibility of dust, liquids, etc. entering the first sub-cavity 1011, thus extending the service life of the wireless microphone.

[0093] In one embodiment, the wireless microphone further includes an anti-roll member 600, which is used to prevent the wireless microphone from rolling. The anti-roll member 600 is sleeved on the body 110 and disposed on the side of the limiting portion 112 away from the second sub-cavity 1012.

[0094] Reference Figure 2 In this embodiment of the invention, the wireless microphone also includes an anti-roll member 600. The cross-section of the anti-roll member 600 can be set in the shape of a triangle, quadrilateral, pentagon, etc. When the wireless microphone is placed on a flat surface, the anti-roll member 600 can prevent the wireless microphone from rolling, reducing the risk of damage from rolling. The anti-roll member 600 can also be made of elastic materials such as rubber or silicone, which plays a certain cushioning role when the wireless microphone is placed or dropped, reducing the risk of collision damage. Specifically, in this embodiment, the anti-roll member 600 is located on the side of the limiting part 112 away from the second sub-cavity 1012, so that the anti-roll member 600 covers the connection between the cover 120 and the limiting part 112, further reducing the possibility of dust, liquids, etc. from the external environment entering the second sub-cavity 1012 and extending the service life of the wireless microphone.
