Abstract

The invention provides a USB peripheral, telephone equipment and a telephone system, and relates to the technical field of communication. The USB peripheral can comprise a USB interface, a selector switch chip and a main chip. A signal pin and an identification pin of the USB interface are connected with corresponding input pins of the change-over switch chip, a first output pin of the change-overswitch chip is connected with a USB pin of the main chip, and a second output pin of the change-over switch chip is connected with an audio pin of the main chip. The power supply pin of the USB interface is connected with the power supply pin of the change-over switch chip, so that the change-over switch chip transmits data corresponding to the detected voltage of the power supply pin, the control signal pin and the identification pin to the USB pin of the main chip through the first output pin, or transmits the data to the audio pin of the main chip through the second output pin. In the scheme, the USB peripheral can realize connection and communication between the USB interface and the USB equipment through the change-over switch chip, and meanwhile, can identify and connect the RJ9 interface of the telephone to realize transmission of audio signals.

Description

Technical field[0001]This application relates to the field of communication technology, and specifically, to a USB peripheral device, a phone device, and a phone system.Background technique[0002]As a more traditional communication tool, the phone needs to realize sound transmission and answering through a connected handle. However, making a call through the handle causes the inconvenience of the call to a certain extent. Considering this problem, it has become a trend to connect a phone with a USB (Universal Serial Bus, Universal Serial Bus) peripheral device, so as to realize communication transmission through the connected USB peripheral device.[0003]In the prior art, when the phone is connected to a USB peripheral device, because the RJ9 interface of the phone does not match the USB interface, an external voice signal processing device is used to convert the USB data signal into an analog signal and input it to the phone RJ9 interface to realize communication.[0004]However, the a...
