Patent ID: 7308231

Claim:
A computer mouse with Bluetooth hand-free handset, capable of matching and communicating with a Bluetooth-enabled wireless communication device, comprising: an electric source module, for providing power to the computer mouse; an optical mouse circuit, for detecting a movement vector caused by a movement of the computer mouse by principles of optical transmitting and receiving to control a computer; a Bluetooth module, coupled to the optical mouse circuit, wherein the Bluetooth module is connected to an antenna for transmitting/receiving signals; an echo cancellation circuit, coupled to the Bluetooth module and used for canceling echoes of audio signals; a sound receptor, coupled with the echo cancellation circuit for receiving the audio signal; an audio signal amplifying circuit, coupled to the echo cancellation circuit and used for receiving and amplifying the audio signal outputted from the echo cancellation circuit; a loudspeaker, coupled to the audio signal amplifying circuit coupled to the audio signal amplifying circuit for playing sounds corresponding to the audio signals from the audio signal amplifying circuit; a function key on the computer mouse, the function key being configured to selectively switch the computer mouse to function as a hands-free handset, wherein the computer mouse is configured to selectively function as a hands-free handset when matched with a Bluetooth enabled mobile phone; and a locking mechanism configured to lock the computer when the locking mechanism detects that the Bluetooth module is not transmitting the signals, the locking mechanism being further configured to unlock the computer when the signals are detected from the Bluetooth module.
