technical field

The utility model relates to a computer keyboard, in particular to a multifunctional keyboard integrating audio and microphone functions.

Background technique

Existing desktop keyboards are generally set independently of audio and earphones, and some improved keyboards add sound channel transmission interfaces on ordinary keyboards to facilitate the insertion of earphones or audio. But these keyboards are not convenient enough for voice and video chat enthusiasts.

Utility model content

The utility model aims at the above-mentioned defects of the prior art, and provides a multifunctional keyboard integrating audio and earphones.

In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

A multi-functional keyboard, comprising a keyboard shell, a button part and a built-in PCB, the PCB is connected to a computer mainframe through a cable, the PCB includes a keyboard input circuit board and a power amplifier circuit board, and a speaker connection seat is provided on the keyboard shell, and the speaker is installed On the speaker connection base, the speaker circuit is connected to the power amplifier circuit board.

Wherein, the keyboard input circuit board and the power amplifier circuit board are independent or integrated.

Wherein, the keyboard shell is also provided with a microphone, and the microphone is connected to the computer host through a built-in PCB.

Wherein, the horn is connected to the horn connecting seat through a hose made of metal, plastic or rubber.

Wherein, the button part is also provided with a button for adjusting the volume of the speaker.

Wherein, the button part is also provided with a button for adjusting the volume of the microphone.

Wherein, the speaker is connected to the keyboard shell by a pluggable DC socket.

Wherein, the microphone is connected to the keyboard shell by a pluggable DC socket.

As can be seen from the above technical solutions, the utility model directly arranges an audio component and a microphone component on the keyboard, making voice or video chatting more convenient; the speaker and the microphone can be disassembled from the keyboard, which brings convenience to transportation and storage; The utility model supports the loudspeaker and the microphone with a hose, so that the orientation of the loudspeaker and the microphone can be changed arbitrarily, so as to achieve good sound effect and convenience in use.
