DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Reference Figure 1-Figure 4 A microphone comprises a power supply 1, a barrel body 2, a sound pickup assembly 3 and a circuit board 5; the power supply 1 comprises a first power supply 11 and a second power supply 12; a first limiting groove 21 for placing the first power supply 11 is provided on the top of the barrel body 2, and the first limiting groove 21 is located at the top of the barrel body 2 and the opening faces upward; the bottom end of the sound pickup assembly 3 is threadedly connected to the top end of the barrel body 2, and the sound pickup assembly 3 is electrically connected to the first power supply 11; the circuit board 5 is located inside the barrel body 2, and the circuit board 5 is electrically connected to the first power supply 11 and the second power supply 12, and a conductive contact 51 and a signal contact 52 are provided on the top of the circuit board 5, both of which are electrically connected to the sound pickup assembly 3.

[0022] Specifically, the first power supply 11 is a dry battery. When the power of the first power supply 11 is exhausted and needs to be replaced, the pickup assembly 3 is rotated and the pickup assembly 3 is unscrewed from the barrel body 2 to separate the pickup assembly 3 and the barrel body 2, exposing the first limiting groove 21, and then the fully charged first power supply 11 is placed into the first limiting groove 21 from the upper opening, and finally the pickup assembly 3 is screwed back into the barrel body 2. At this time, one end of the first power supply 11 is electrically connected to the bottom of the pickup assembly 3, and the conductive contact 51 and the signal contact 52 are both electrically connected to the pickup assembly 3.

[0023] By providing a detachable barrel body 2 and a pickup assembly 3, the first power supply 11 is arranged in the first limiting groove 21 of the barrel body 2, thereby solving the problem that the microphone battery is unstable and easy to scatter; by adding conductive contacts 51 and signal contacts 52, the problem of poor contact of conventional microphone batteries is solved.

[0024] like Figure 3 As shown, in some embodiments, the pickup assembly 3 includes a pickup housing 31, a pickup 32 and a PCB board 33. The bottom end of the pickup housing 31 is threadedly connected to the barrel 2, the top of the pickup housing 31 is movably connected to the pickup 32, the bottom of the pickup housing 31 is fixedly connected to the PCB board 33, the pickup 32 and the PCB board 33 are electrically connected, and the PCB board 33 is electrically connected to the first power supply 11, the conductive contact 51 and the signal contact 52 respectively.

[0025] The top and bottom ends of the pickup housing 31 are both provided with threads. The pickup housing 31 serves to connect the barrel body 2 on the one hand, and to store the pickup 32 and the PCB board 33 on the other hand, so that the pickup assembly 3 can be disassembled and replaced as a separate assembly without affecting the electrical connection between the pickup 32 and the PCB board 33.

[0026] like Figure 3 As shown, in some embodiments, the microphone also includes a protective cover 4, which includes a top cover 41 and a cover body 42, the top end of the cover body 42 is threadedly connected to the top cover 41, and the bottom end of the cover body 42 is threadedly connected to the top of the pickup housing 31, the top of the top cover 41 is a metal mesh, and the cover body 42 is made of metal.

[0027] The metal top cover 41 and the cover body 42 are durable, and the mesh top cover 41 enables the microphone 32 to better collect external sounds. The inner wall of the cover body 42 is provided with a sponge, which prevents droplets and dust from falling onto the microphone 32. The top cover 41 and the cover body 42 are separated by rotating them, and the sponge can be replaced.

[0028] like Figure 3 As shown, in some embodiments, the cover body 42 is provided with 2 to 6 side edges 421 , and 4 to 8 strip-shaped holes 422 are provided between adjacent side edges 421 .

[0029] Preferably, four side edges 421 are arranged at equal intervals, and six strip holes 422 are arranged between adjacent side edges 421. The side edges 421 play a supporting role, making the structure of the cover body 42 stronger. The arrangement of the strip holes 422 enables the microphone 32 to better receive external sounds. The structure of the cover body 42 is stronger and more resistant to falling than a conventional microphone protective cover with a full mesh structure.

[0030] like Figure 3 As shown, in some embodiments, the outside of the pickup 32 is wrapped with a rubber plug 34 , and the rubber plug 34 is blocked at the top of the pickup housing 31 .

[0031] like Figure 2 to Figure 4 As shown, in some embodiments, one side of the PCB board 33 is electrically connected to the pickup 32 through an electric wire, and the other side of the PCB board 33 is provided with a first conductive area 331, a second conductive area 332 and a third conductive area 333, the first power supply 11 and the conductive contact 51 are both electrically connected to the first conductive area 331, the signal contact 52 includes a first signal contact 521 and a second signal contact 522, the first signal contact 521 and the second conductive area 332 are electrically connected, and the second signal contact 522 and the third conductive area 333 are electrically connected.

[0032] The rubber plug 34 serves to connect the pickup 32 and the pickup housing 31. During the assembly of the microphone, the PCB board 33 and the wires need to be connected by tinning. By pulling out the rubber plug 34, the side of the PCB board 33 that needs to be tinned is exposed, which facilitates the tinning operation. After the tinning is completed, the rubber plug 34 is plugged into the top of the pickup housing 31 to fix the pickup 32 and hide the wires inside the pickup housing 31, thereby protecting the wires and making the connection between the pickup 32 and the PCB board 33 more stable.

[0033] like Figure 4 As shown, in some embodiments, the first conductive area 331 is circular and located at the center of the PCB board 33, the second conductive area 332 is located outside the first conductive area 331 and is annular, and the third conductive area 333 is located outside the second conductive area 332 and is annular.

[0034] Specifically, the current first flows from the positive electrode of the first power supply 11 through the first conductive area 331 to the other side of the PCB board 33, and then flows to the pickup 32 through the wire. The current on the pickup 32 flows to the first conductive area 331 of the PCB board 33 through another wire, and then flows from the first conductive area 331 to the conductive contact 51. Finally, the current flows through the conductive contact 51 through the circuit board 5 to reach the negative electrode of the first power supply 11, forming a current loop, thereby completing the power supply to the pickup 32.

[0035] The pickup 32 converts the collected audio signal into an electrical signal, transmits the electrical signal to the third conductive area 333 on the PCB board 33 through the wire, and then transmits the electrical signal from the third conductive area 333 to the circuit board 5 through the second signal contact 522 for amplification and noise reduction.

[0036] The processed electrical signal is then transmitted to the second conductive area 332 through the first signal contact 521, and then transmitted from the second conductive area 332 to the microphone 32 through the wire, and the microphone 32 forwards the electrical signal into an audio signal and plays it externally.

[0037] like Figure 2 As shown, in some embodiments, the barrel body 2 also includes a second limiting groove 22 for placing the second power source 12 and the circuit board 5.

[0038] By setting the second limiting groove 22 , the space of the barrel body 2 is fully utilized, the circuit board 5 is placed on one side of the barrel body 2 , and the second power supply 12 is placed on the bottom of the barrel body 2 .

[0039] like Figure 3 As shown, in some embodiments, the circuit board 5 is provided with a display screen 53 and control buttons 54 .

[0040] The display screen 53 can display the volume, power level and mode of the microphone, and the control buttons 54 include a volume increase button, a volume decrease button and a power switch button.

[0041] like Figure 3 As shown, in some embodiments, a first notch 23 corresponding to the display screen 53 and a second notch 24 corresponding to the control button 54 are provided on the side of the barrel 2, and a power interface 25 is provided at the bottom of the barrel 2, and the power interface 25 is electrically connected to the second power source 12.

[0042] The display screen 53 is exposed from the barrel body 2 through the first slot 23 , so that the user can view the display screen 53 ; the control button 54 is exposed from the barrel body 2 through the second slot 24 , so that the user can control the microphone; the power interface 25 is specifically a Type-C interface, which is used to connect a DC power supply with a voltage of 5 volts. The setting of the power interface 25 facilitates the charging of the second power supply 12 .
