Fig. 1 shows a wireless transmission / reception means mounted on a clip-type radio transceiver, which is equipped with a Bluetooth module 11 and has an antenna for short-range radio communication with the cellular phone.

The Bluetooth module 11 is a main component of the wireless transmission and reception means. Hereinafter, the present invention will be described in detail. However, the present invention is not limited thereto, and the same effect can be obtained by using an infrared transmitting / receiving module having similar operation or configuration of a peripheral circuit in place of the Bluetooth module 11, and Detailed description will be omitted.

Here, Bluetooth (Bluetooth Module) refers to the development code name of the wireless data communication standard developed by Ericsson of Sweden, IBM of IBM and Intel, Nokia of Finland, Toshiba of Japan, etc. The goal is to realize 10m wireless data communication.

The selected 1Mbps is a transmission speed that can be realized relatively easily and inexpensively using 2.4HGz's Industrial Scientific Medical (ISM), which can be used without a user's license, and the transmission distance of 10m is carried by the user in the office. It was decided by the judgment that the transmission distance between the existing device and the device installed on the desk is sufficient. In this case, the transmission speed 1Mbps and the transmission distance 10m may of course vary depending on the license requirements and transmission capacity.

On the other hand, the infrared communication standard [Infrared Data Association] (version 1.1) method, which is the industry standard for the current telecommunication period data communication, leads the Bluetooth with the maximum data transmission rate of 4Mbps but the shortest transmission distance is 1m.

In addition, Bluetooth adopts CVSD (Continuous Variable Slope Delta Modulation), which is a voice encoding method, and can be used for voice transmission as well as text data transmission. In addition, cryptography is used to maintain the confidentiality of communications.

However, the biggest advantage of Bluetooth compared to the infrared communication method is that it can communicate with other information communication devices in a bag or pocket. For example, the Bluetooth method has the advantage of being able to transmit image data photographed by a digital camera without any cumbersome procedures, such as cable connection with a PC or a mobile phone, in any state within a certain distance. .

Here, as an example of the call switch 14, a toggle switch turned on / off by an external pressure, a touch switch turned on / off by contact with a human body, or a photo coupler turned on / off by a proximity approach of an object may be used. have. Since the toggle switch needs to be directly applied by the user, the wearing state of the voice transceiver worn on the ear may be modified, but the touch switch may control the operation of the voice transceiver even with a light contact with the human body. In particular, the photo coupler drives a voice transceiver to make a phone call with the other party by simply bringing a hand or other object close to the photo coupler without the user touching the voice transceiver. Since the user can be provided, the user does not have to use his hand to listen to a telephone call or music. Of course, when using a touch switch or a photo coupler as a call switch, it is natural to remove the call buttons so that they are exposed to the outside.
