Problems solved by technology

Existing wireless microphones often encounter the situation that the battery power is exhausted during use. At this time, the battery needs to be replaced. Some microphones that use rechargeable batteries often need to be placed in the charging base in a specific direction to charge. There are certain operations Difficulty affects user experience, so we propose a wireless microphone that supports reversible charging to solve the above problems

Embodiment 1

[0023] see Figure 1-4 , a wireless microphone that supports reversible charging, including a microphone body and a charging base 2 adapted to the microphone body, the microphone body includes a housing 1, a microphone 3 is fixedly installed on the top of the housing 1, and the housing 1 is fixedly installed with a rechargeable lithium battery. The bottom of the housing 1 is provided with a positive charging contact 4 and a negative charging contact 12 electrically connected to the rechargeable lithium battery. The inner bottom of the charging base 2 is provided with a positive charging contact. Point 4 and the four contact springs corresponding to the negative charging contact 12.

[0024] The main body of the microphone can be placed in the charging base 2, the positive charging contact 4 and the negative charging contact 12 at the bottom of the housing 1 are in contact with the contact shrapnel of the charging base 2, and the charging base 2 is connected to an external powe...

Embodiment 2

[0027] On the basis of Example 1, in addition, as Figure 5-6 As shown, the four contact shrapnels are located in the middle area of ​​the inner bottom of the charging base 2 in a rectangular distribution, and the four contact shrapnels are respectively the first positive shrapnel 13, the first negative shrapnel 14, the second positive shrapnel 15 and the second negative shrapnel 16. The first positive shrapnel 13 and the second positive shrapnel 15 are arranged diagonally, and the first negative shrapnel 14 and the second negative shrapnel 16 are arranged diagonally.

[0028] When the main body of the microphone is placed inside the charging base 2 with the front facing outward, the positive charging contact 4 of the housing 1 is in contact with the first positive elastic piece 13, and the negative charging contact 12 is in contact with the first negative elastic piece 14. ; And when the microphone main body is put into the inside of the charging base 2 with the reverse side ...

Embodiment 3

[0030] On the basis of Embodiment 2, in addition, the left side of the housing 1 is provided with a laser pointer button 7 and a PPT page turning button 8, and the right side of the housing 1 is provided with an on / off key 9, a mute key 10 and a volume key 11. The bottom of the body 1 is provided with a power indicator 6, and the multiple functional buttons provided on the body 1 improve the versatility of the microphone body, and the use of the microphone is more convenient. Furthermore, the charging port 5 is a Micro USB charging interface, which is convenient for passing data The cord is used for charging, which greatly increases the practicability of the microphone.

Abstract

The invention discloses a wireless microphone supporting positive and negative discharging and charging, and relates to the technical field of microphones. The microphone comprises a microphone mainbody and a charging base matching the microphone main body. A rechargeable lithium battery is fixedly installed in the shell. A positive charging contact and a negative charging contact which are electrically connected with the rechargeable lithium battery are arranged at the bottom of the shell, and four contact elastic pieces corresponding to the positive charging contact and the negative charging contact are arranged at the bottom in the charging base. The shell of the device is of a cuboid structure, so that the risk that the microphone main body rolls down to the ground is avoided; the positive charging contact, the negative charging contact and four contact elastic pieces are designed; the microphone main body can be charged in the charging base from the front side and the back side;the microphone main body does not need to be placed in a specific direction, which facilitates the charging operation of a user, and improves the use experience of the user; the side face of the shell is provided with the multiple function keys and a charging port formed in the bottom, and thus practicability of the microphone is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of microphones, in particular to a wireless microphone that supports reversible charging. Background technique [0002] Microphone, scientifically called microphone, is an energy conversion device that converts sound signals into electrical signals. It is transliterated from the English word "Microphone", also known as microphone and microphone. In the 20th century, the microphone developed from resistive conversion of sound and electricity to inductive and capacitive conversion, and a large number of new microphone technologies gradually developed, including aluminum ribbon, dynamic coil and other microphones, as well as the widely used condenser microphones and electret microphones. body microphone. [0003] Wireless microphones are widely used in teaching, conferences, speeches and other occasions because they are free from the constraints of wires and have the characteristics of flexible use. Existing ...
