Embodiment 1

[0048] Embodiment 1: In this example, a keyboard-microphone combination device and an external additional device are used to connect to a computer in order to illustrate their structures.

[0049] The keyboard-microphone combination device is composed of two input devices, the computer PS / 2 interface keyboard and the microphone. figure 2 In the keyboard microphone combination device, ① is the keyboard, and ② is the external wire of the keyboard. ③ is the keyboard PS / 2 interface plug, ⑧ is the microphone built in the keyboard, which is installed under the panel between the character key area and the number key area of ​​the keyboard, and there is a small hole above the microphone for conducting sound. The ground wire of the microphone is connected to the keyboard power ground (GND), and the other end of the microphone is connected to the microphone signal wire and the microphone bias wire. They are integrated with the four wires of the keyboard, and all wire harnesses are outp...

Embodiment 2

[0054] Embodiment 2: as Figure 4 , the built-in additional device is on the computer motherboard, one end is connected to the redundant terminals 2 and 6 of the PS / 2 keyboard interface on the motherboard, and the other end is connected to the keyboard microphone signal end wire and microphone of the front panel audio connector (FP-AUDIO) on the computer motherboard There is a connector A in the middle of the connecting line for the bias terminal wire, and the connector A can be short-circuited with a jumper cap. The specifications and dimensions of the connector and the jumper cap are the same as those of the front panel audio connector and the jumper cap on the motherboard. The connecting wires use copper on the circuit board, from TPA1 and TPA2 to TP1 and TP2 of the PS / 2 keyboard (KEY BOARD) interface, such as Figure 4 In the dashed box and image 3 Shown in thick solid line. For computers without front-panel audio connection connectors on the motherboard, built-in additi...
