Problems solved by technology

If it is distributed to each teacher, a set must be distributed, which is costly and inconvenient to carry. If not distributed, it will be a problem in the management of such small wireless devices
[0006] In fact, the mouse and the microphone are inseparable in multimedia demonstration occasions. However, there is currently no product that combines the two organically.

Embodiment 1

[0053] Embodiment 1: The cost of this embodiment is relatively low, and it is also very convenient to use. The specific process is as follows:

[0054] As shown in Figures 2, 3, 7, 8, and 9, when the demonstrator puts the transmitter body 301 into the transmitter placement groove 313 of the receiver body 314, the pin data line interface 308 of the transmitter and the receiver's The pin data line 312 is electrically connected, and at the same time when it is just connected, the power management circuit 207 composed of a single-chip microcomputer (such as AT89C1051) is triggered, and the wireless radio frequency receiving circuit 209 (such as nRF24E1 wireless radio frequency transceiver chip) is triggered. The power-off operation of the time makes the RAM embedded in the radio frequency receiving circuit 209 empty, and then reconnects the power supply. 25X320EEPROM chip) has been connected with the pin data line 208 of the receiver circuit 2 part through the pin data line 106, s...

Embodiment 2

[0059] Embodiment 2: As shown in Figures 4, 5, 6, 7, 8, and 10, the difference between this embodiment and Embodiment 1 is that the control of its mouse displacement signal perception components and audio circuit on-off is different, and other aspects Exactly the same, as follows:

[0060] When the demonstrator uses it in his hand, the light touch switch S1 button 310 on the bottom surface of the transmitter body 301 is released, and the audio circuit 102 and the mouse signal detection circuit 103 on the upper surface of the transmitter are connected; when the demonstrator puts it on the desktop During use, the light touch switch S1 button 310 on the bottom surface of the transmitter body 301 is pressed, the audio circuit 102 and the mouse signal detection circuit 103 on the upper surface of the transmitter are disconnected, and the mouse signal detection circuit 101 on the lower surface of the transmitter is connected. In this example, the upper and lower surface mouse displa...

Abstract

A method for realizing both functions of audio and radio for mouse includes setting signal sensing component at top surface and bottom surface of emitter on mouse for realizing functions of desk use and hand use, using microphone on top surface of emitter to realize radio microphone function, using contact switch at bottom surface of emitter to realize control of switch on or off state, thus switching off microphone function when mouse is used on desk and switching on microphone function when mouse is used by hand.

Description

technical field [0001] The invention relates to a method and device for realizing the function of a dual-purpose audio wireless mouse, in particular, it can realize that it can be used on the desktop like an ordinary wireless mouse, and can be used with one hand when the mouse body is placed on the desktop. The microphone function on the mouse body is automatically closed when the mouse is used, and the method and device for automatically opening the microphone function when the mouse is held in use. Background technique [0002] With the rapid development of computer, Internet and multimedia technology, the cost of multimedia teaching system has been greatly reduced, and it has become a common teaching equipment in colleges and universities and even primary and secondary schools. Mouse and microphone are necessary equipment for multimedia teaching and conference briefing, but the corresponding equipment that appears for this purpose at present cannot meet the needs of users...
