Description

Remote control handset using handheld wireless communication for handheld information equipment (PDA etc.) equipped with wireless mobile communication module and short range wireless communication device {Wireless Remocon HandSet for Mobile Information Equipment}

The present invention relates to a wireless handset device using a combination of a short-range wireless connection standard (IEEE 802 series) such as Bluetooth, an analog / digital conversion technology of voice data, and data control and programming technology. While wireless hands-free was capable of simple call control and voice transmission and reception via earsets, the present invention is connected to a portable information device such as a PDA through a short-range wireless connection, which enables a conventional mobile phone to take out or manipulate a portable information device. Provides a device that can implement most of the features

When a portable information device equipped with a wireless mobile communication module such as a PDA receives a voice call, the device of the present invention receives it from a wireless data processing unit through short-range wireless communication to control the controller, data conversion unit, or output device (speaker or Earset), the user's control command for dialing to make a call or for receiving an incoming call or a message is output through a control unit at a key input unit and transmitted to a portable information device through a wireless data processing unit of the device of the present invention. Take control. Whereas the existing wired / wireless hand-free products for mobile phones were capable of simple call control and voice transmission / reception, the device of the present invention can perform most operations on mobile phone functions in portable information devices, such as incoming ringtone or message arrival notification or voice call. Caller identification using its own LCD display when receiving a call, dialing a phone number or hotkey using its own keypad and remote control function, displaying information on the power status of a portable information device and the sensitivity of a mobile phone or call, connection status, mobile phone preferences In addition to the function of listening to music using the music playback function of the portable information device, various player control, call recording and external recording function through the microphone, etc. The perfect company that makes everything possible The implementation convenience.

Displaying layout form

The device of the present invention is a short-range wireless access data processing unit (transmitter and receiver) for communicating with a mobile phone module of a mobile information device in which a wireless mobile communication module (mobile phone module) is built or attached, and digital voice data and control data received therefrom. And a control unit for processing the data, a data conversion unit, and a microphone, a speaker, an earset terminal and a liquid crystal display unit for outputting and displaying the converted data, and a key input unit. The wireless data processing unit, which is a transmission / reception module for short-range wireless access, uses Bluetooth or other IEEE 802 standardized short-range wireless access protocols and controllers, which is an IEEE proposed standard, to enhance device compatibility, and the controller is configured with a programmed microcomputer circuit. The data converter processes voice data using a D / A or A / D converter.

The device of the present invention is frequently used as a mobile information device having a high performance and a large capacity of data processing capability, such as a PDA, instead of a conventional mobile phone, in accordance with the rapid change of the wireless Internet and mobile computing environment using a mobile phone network. Unlike the existing hands free, it is the most effective handset device designed to compensate for the inconvenience of using heavy mobile information devices and to prevent unnecessary waste of power by the large-capacity color liquid crystal display device. Even if you do not take out or operate the portable information device, which is the main terminal device, you can completely solve a series of operations related to voice calls such as receiving voice calls and messages, making calls by dialing, and listening to music. Provides convenience for doing so.
