It relates to a transceiver.

In general, a mobile phone is a mobile communication terminal capable of making a call regardless of time or place. However, in order to make a phone call with the other party, the mobile phone must be held close to the ear, so the mobile phone must be held with one hand like a normal phone.

In order to solve such inconvenience, a hands-free mobile phone has been developed. However, this has the advantage of not having to hold the mobile phone with one hand when talking with the other party, but the caller is limited in the range of activities since the mobile phone and the earphone must be connected by wire. In other words, as can be seen in the Republic of Korea Registered Utility Model No. 20-247574 "speaker phone attached to the cell phone terminal accessories", conventionally simply attach a cell phone-type speaker phone to the mobile phone terminal to always carry Regardless of your situation, you can immediately recognize that a call is received from a mobile phone and make a call.

Hereinafter, the present invention will be described in detail.

Fig. 1 shows a wireless transmission / reception means mounted on an ear transceiver wireless transceiver, which is equipped with a Bluetooth module 11 and has an antenna for short-range wireless 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 at low cost by using 2.4HGz ISM (Industrial Scientific Medical) which can be used without a user's license. 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 as it is in any state within a certain distance without cumbersome procedures such as cable connection with a PC or a mobile phone, and is a wireless communication method that has been in the spotlight recently.

A control unit 12 is connected to the Bluetooth module 11, and the control unit 12 is a Bluetooth module 11 for short-range wireless communication and a speaker 15 for a telephone call according to an operation of the call switch 13. And driving of the microphone 16 and the like.

The call switch 13 for selecting the operation of the Bluetooth module 11 is linked to the call button configured in the case, and the call / standby for the short-range wireless call between the voice transceiver including the Bluetooth module 11 and a mobile phone. It automatically plays the role of selecting or automatically dialing the phone number of the other party.

Here, as an example of the call switch 13, 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 can make a phone call with the other party by driving the voice transceiver just by bringing the hand or other object close to the photo coupler without the user touching the voice transceiver. You do not have to do. 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.

A receiver, which is received from the other party via a mobile phone (not shown) and outputs a handset sound processed by the Bluetooth module 11, is mounted to the case so that a part thereof protrudes outward so that it is easy to attach to the ear, and the Bluetooth module 11 The microphone 16, which is processed by and collects the sound of the call sent to the mobile phone, is also mounted at the bottom of the case so as to be close to the user's mouth.

In addition, the wireless transceiver including the Bluetooth module 11 and the control unit 12 is equipped with a battery 17 for supplying driving power, which charges the external power input through the charging jack 18, It is supplied to a wireless transceiver.

In addition, the control unit 12 is connected to the volume up / down switch 14, etc. This volume up / down switch 14 is a switch for adjusting the volume of the sound is output through the speaker 15 to the case It is linked to the configured volume up / down button.
