[Previous technology] 5 With the continuous change of human economic activity mode, short-range wireless communication technology has gradually been paid attention to. Among them, Bluetooth wireless technology has low price, low power consumption and can provide voice data at the same time. Transmission and other advantages, and attracted manufacturers to compete to invest in the development of Bluetooth-related products. The application of Bluetooth technology can be said to be quite extensive. Since it can transmit data and sound signals in the 2.45GHz 10 frequency band, it can be used in telephones, computers, exchange of electronic business cards, video and wireless headsets. The Bluetooth radio has the functions of speaking and receiving through the public switched telephone network. As shown in the first figure, it is a current hardware module architecture of a Bluetooth wireless phone 1, which includes a telephone 11 and a telephone base 12. When electricity 15 and electricity 1 are to be used, a dial signal is generated by dialing through a keypad 110 of the phone 11, and after being properly converted by a digital signal processor 111, it is sent by the Bluetooth module 112 on the phone 11 to the Bluetooth on the phone 12 The module 121 sends the dial-up signal to another digital signal processing circuit 122 for conversion processing, and then sends it to a PSTN (Public Switched Telephone Network) interface 123 for dial-up action. After 20 calls, a PSTN is established. The communication path between the interface 123, the digital signal processing circuit 122, the Bluetooth module 121, the Bluetooth module 112, the digital signal processing circuit 111, and the sound interface 113 is for users to talk to each other through the Bluetooth wireless phone 1. However, from the above, it is known that the conventional Bluetooth wireless phone 1 only has a single function of telephone 6 591929 发明, invention description (1), so when the user is walking around and answering the phone, he also wants to use the wireless When listening to the music played by the computer (here refers to the limited range of activities that Bluetooth can apply), you must use another wireless method, such as setting up a Bluetooth wireless transmission 5 module on the computer to make the computer sound The music output from the card is wirelessly output and listened with a Bluetooth headset. However, in this case, not only will it cost more, but it will also be necessary to switch between the phone and the headset, and increase the hardware equipment (wireless phone, Bluetooth headset) worn on the body, which is inconvenient. [Summary of the Invention] 10 Therefore, an object of the present invention is to provide a Bluetooth wireless telephone unit which integrates a wireless telephone with an audio signal receiving function, has dual functions, low price, is convenient to use, and reduces the amount of hardware. Therefore, the Bluetooth wireless telephone set of the present invention includes a first transmitting / receiving device and a second transmitting / receiving device. The first transmitting / receiving device has a first operation mode and a second operation mode. The second transmitting / receiving device is wirelessly connected with the first transmitting / receiving device, and can selectively connect a telephone line and an audio signal. When the first transmitting / receiving device operates in the first operation mode, it sends a first control signal to instruct the second transmitting / receiving device to establish a telephone conversation path, so that the first transmitting / receiving device 20 can pass through the first Two transmitting / receiving devices are connected to the telephone line for wireless telephone communication. When the first transmitting / receiving device operates in the second operation mode, it sends a second control signal to instruct the second transmitting / receiving device to establish an audio signal. The transmission path enables the audio signal to be wirelessly transmitted through the second transmitting / receiving device to the first transmitting / receiving device for output. With this, it reaches 7 591929 玖, invention description (3) = has the dual functions of choosing to use a wireless phone or receiving audio signals 15 20 Furthermore, the Bluetooth module switching device of the present invention includes _Bluetooth Money controller and-audio channel controller. The Bluetooth module is used to receive the control signal and the first control signal. The CPU is connected to the Bluetooth. The audio channel controller is connected to the central processing unit, and is selectively connected to a telephone line under the control of the two central processing units. When the central processing unit receives the first control signal, the control unit is controlled by the channel control unit. ㈣ is connected to the telephone line; and when the central processor receives a control signal, it controls the audio channel controller and the audio signal to be connected.
