Microphone and method of use

Abstract

The present invention discloses a microphone and a method of use, and relates to the technical field of microphones, including a transmitter body and a disassembly assembly component. During the use of the present invention, when receiving sound, a groove is provided on the outside of the sound receiving hole, and a structure design of a spray-proof sponge is embedded in the groove, which facilitates the replacement of the spray-proof sponge and can reduce wind noise and prevent the microphone from being sprayed. After the sound waves are initially noise-reduced by the spray-proof sponge, they enter the sound receiving tube and reduce the noise in the sound waves in the process of penetrating the noise-reducing cotton, achieving a secondary noise reduction effect. Thereafter, the sound waves propagate downward in the guide hole and are picked up by a pickup. The pickup converts the sound wave signal into an electrical signal and filters the noise in the signal again through a built-in filter module in a circuit board, achieving a tertiary noise reduction effect. The present application solves the existing technical deficiencies that the recording effect of the collar clip microphone is easily disturbed by environmental noise through a triple noise reduction structural design, and has stronger applicability.

Description

Technical Field

[0001] The present invention relates to the technical field of microphones, and in particular to a microphone and a use method thereof. Background Art

[0002] A lavalier microphone is a type of wireless microphone, generally a condenser microphone, and can be used in large-scale mobile conferences, recordings, public communications, outdoor speeches, lectures, and other occasions. The lavalier microphone is small in size and light in weight, and can be clamped on the user's collar through a clamping mechanism, having the advantage of being easy to use. However, existing lavalier microphones are easily affected by external noise when in use, and have poor noise reduction capabilities.

[0003] For example, the patent document with application number CN202310983961.8 discloses a collar microphone with noise reduction function and a noise reduction method. This invention patent improves the noise reduction effect by performing multiple noise reduction processes, and the pickup head is installed inside the shell, which will not cause friction with external clothing. The pressure plate is connected to the shell by a snap-on method, which is convenient for replacing or cleaning the anti-spray sponge.

[0004] Looking at the comparative document, the applicant found the following deficiencies: First, it follows the back clip fixing technical solution commonly used in lavalier microphones in the prior art, which affects the aesthetics and causes damage and deformation of clothing; second, the comparative document can only replace or clean the anti-spray sponge on the outside of the body, and the anti-spray sponge is only used as a means of initial noise reduction, while the noise reduction cotton as a subsequent noise reduction means is arranged inside the body and cannot be cleaned, and the guide holes will also be blocked by impurities such as sweat during long-term use, which greatly reduces the sound receiving effect of the microphone arranged inside the body; finally, the lavalier microphone designed in the comparative document is limited by the capacity of the battery, which limits the continuous working time, and no heat dissipation structure is designed. The lavalier microphone is close to the user's skin when used, and is prone to overheating.

[0005] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a microphone and a method of use are proposed. Summary of the invention

[0012] Furthermore, docking holes are symmetrically provided on both sides of the top rear end of the transmitter body, and the docking holes are interference fit with the docking blocks at both ends of the top of the rear cover.

[0013] Furthermore, an upper cavity is opened on the inside of the transmitter body, and a sound receiving hole is opened at the middle end of the top of the upper cavity.

[0014] Furthermore, a lower cavity is provided at the lower part of the transmitter body, and the connection between the lower cavity and the upper cavity is separated by a partition, and a through hole is provided in the middle of the partition.

[0015] Furthermore, a processing component is arranged inside the lower cavity, and the processing component includes a circuit board, a Bluetooth antenna, a sound pickup module, a filtering module, a protective frame, a heat conductive sheet and cooling fins.

[0016] Furthermore, the method of use includes the following steps:

[0017] Step 1: There are two optional wearing methods for the transmitter body of the present application. One is to buckle the magnetic badge on the top of the front of the transmitter body from the embedded groove, and then place the magnetic badge on the outside of the clothes, and place the transmitter body on the inside of the clothes. The magnetic adsorption of the magnetic badge and the transmitter body realizes the hidden fixation of the collar microphone.

[0018] Step 2: Align the blocks on both sides of the back cover with the slots on both sides of the transmitter body and snap them in, so that the sound receiving tube is embedded in the upper cavity above the inside of the transmitter body.

When the circuit board is in use, the heat is transferred to the heat dissipation fins through the heat conducting sheet, and the heat dissipation is convectively dissipated through the heat dissipation window at the bottom of the front of the transmitter body;

[0019] Step 3: When receiving sound, a groove is opened on the outside of the sound receiving hole and a spray-proof sponge is embedded in the groove. This facilitates the replacement of the spray-proof sponge and can reduce wind noise and prevent mic spray. The sound waves after the initial noise reduction by the spray-proof sponge enter the sound receiving tube and reduce the noise in the sound waves in the process of penetrating the noise reduction cotton, which has the effect of secondary noise reduction. After that, the sound waves propagate downward in the guide hole and are picked up by the pickup. The pickup converts the sound wave signal into an electrical signal and then filters out the noise in the signal again through the built-in filter module of the circuit board, which has the effect of tertiary noise reduction.

[0020] The present invention provides a microphone and a method of using the microphone, which have the following beneficial effects:

[0021] 1. During the use of the present invention, when receiving sound, a groove is opened on the outside of the sound receiving hole, and a spray-proof sponge is embedded in the groove. This facilitates the replacement of the spray-proof sponge and can reduce wind noise and prevent mic spray. The sound waves after the initial noise reduction by the spray-proof sponge enter the sound receiving tube and reduce the noise in the sound waves in the process of penetrating the noise reduction cotton, thereby achieving a secondary noise reduction effect. Thereafter, the sound waves propagate downward in the guide hole and are picked up by the microphone. The microphone converts the sound wave signal into an electrical signal and then filters out the noise in the signal again through the built-in filtering module of the circuit board, thereby achieving a tertiary noise reduction effect. The present application is different from the traditional collar-clip microphone in that the microphone is arranged inside the cavity of the transmitter body, and the triple noise reduction structural design is used to solve the prior art deficiency that the collar-clip microphone is easily disturbed by environmental noise in recording effect.

[0022] 2. During the use of the present invention, the card blocks on both sides of the back cover are aligned with the card slots on both sides of the transmitter body and buckled in, so that the sound receiving tube is embedded in the upper cavity above the inside of the transmitter body. Thereafter, the back cover is pushed upward, so that the docking blocks on both sides of the top of the back cover are inserted into the docking holes at the corresponding positions at the rear end of the top of the transmitter body for fixing, and the DC male plug on the back cover is connected with the DC female plug on the transmitter body to establish an electrical connection from the battery to the circuit board and various functional modules, and a protective frame made of rubber material is set on the periphery of the circuit board and foam is set on the inner side of the battery to play a role in collision protection. When the circuit board is in use, the heat is transferred to the heat dissipation fins through the heat conductive sheet, and through Convection heat is dissipated through the heat dissipation window at the bottom of the front side of the transmitter body, effectively solving the prior art problem that the collar microphone is close to human skin and is prone to overheating. The present application integrates the sound receiving tube on the back cover and designs the back cover as a split structure for sliding installation. On the one hand, it is convenient for the disassembly, assembly and replacement of the noise reduction cotton as a consumable material and the anti-blocking and dredging of the guide hole. Combined with the existing technical solution of replacing the anti-spray sponge in the sink, the transmitter body of the present application is easy to maintain, ensuring the efficient operation of the triple noise reduction structure design. On the other hand, the service life of the transmitter body can be effectively extended by replacing the battery, solving the prior art problem that the collar microphone has a short continuous working time due to the limited battery capacity.

[0023] 3. During the use of the present invention, there are two optional wearing methods for the transmitter body of the present application. One is to buckle the magnetic badge on the top front of the transmitter body out of the embedding groove, and then place the magnetic badge on the outside of the clothes, and place the transmitter body on the inside of the clothes. The magnetic adsorption of the magnetic badge and the transmitter body is used to achieve the hidden fixation of the collar microphone. The second is to put a silicone sleeve on the outside of the transmitter body and connect a lanyard, and put the lanyard around the neck to hide the transmitter body inside the clothes. Compared with the existing technology that needs to be fixed on the clothes by a back clip, the present application uses the structural design of the above two wearing methods. It is more beautiful and prevents the back clip from damaging the clothes, and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

8. A microphone according to any one of claims 1 to 7, characterized in that: The method of use includes the following steps: Step 1: There are two optional wearing methods for the transmitter body (1) of the present application. One is to buckle the magnetic badge (4) on the top of the front of the transmitter body (1) out of the embedding groove (2), and then place the magnetic badge (4) on the outside of the clothes, and place the transmitter body (1) on the inside of the clothes, so that the collar microphone is hidden and fixed by the magnetic adsorption of the magnetic badge (4) and the transmitter body (1). The other is to put a silicone sleeve (5) on the outside of the transmitter body (1) and connect it to the hanging rope (6), and put the hanging rope (6) around the neck so that the transmitter body (1) is hidden inside the clothes; Step 2: Align the blocks (2202) on both sides of the rear cover (2201) with the slots (8) on both sides of the transmitter body (1) and snap them in, so that the sound receiving tube (2207) is embedded in the upper cavity (14) inside the transmitter body (1). Then, push the rear cover (2201) upward, so that the docking blocks (2203) on both sides of the top of the rear cover (2201) are inserted into the docking holes (12) at the corresponding positions at the rear end of the top of the transmitter body (1) for fixing, and make the DC male plug (2204) on the rear cover (2201) and the transmitter body (1) align. ) is connected to the DC female plug (13) on the transmitter body (2101), an electrical connection is established between the storage battery (2205) and the circuit board (2101) and each functional module, and a protective frame (2105) made of rubber material is set on the periphery of the circuit board (2101) and a foam (2206) is set on the inner side of the storage battery (2205) to play a role in collision protection. When the circuit board (2101) is in use, the heat is transferred to the heat dissipation fins (2107) through the heat conduction sheet (2106), and the heat dissipation is convectively dissipated through the heat dissipation window (7) at the bottom of the front side of the transmitter body (1); Step 3: When receiving sound, a groove (16) is provided on the outside of the sound receiving hole (15), and a spray-proof sponge (17) is embedded in the groove (16). This facilitates the replacement of the spray-proof sponge (17) and can reduce wind noise and prevent the microphone from being sprayed. After the initial noise reduction by the spray-proof sponge (17), the sound waves enter the sound receiving tube (2207) and reduce the noise in the sound waves in the process of penetrating the noise reduction cotton (2208), achieving a secondary noise reduction effect. Thereafter, the sound waves propagate downward in the guide hole (2209) and are picked up by the pickup. The pickup converts the sound wave signal into an electrical signal and then filters out the noise in the signal again through the built-in filter module (2104) of the circuit board (2101), achieving a tertiary noise reduction effect.
