[Problem to be Solved by the Invention] The conventional remote control transmitter is constructed as described above, but the selector switch 11 must be manually preset to a position corresponding to the electronic device for each electronic device to be used. However, the operation is troublesome and difficult.

[0005]

[Means for Solving the Problems] The present invention was invented in view of the above problems, and provides a key matrix whose switching is controlled by a key matrix switching control section, and a display switching switch provided corresponding to the key matrix. A display unit whose switching is controlled by a control unit, a key input determination unit that determines which key of the key matrix is operated in accordance with the display content of the display unit, and command data corresponding to each display content of the display unit. and an output signal switching control section that reads command data corresponding to the operated key from the memory and outputs the command signal from the output section based on the judgment signal obtained from the key input judgment section. The state of the keys of the key matrix and the display contents of the display section are changed by applying a switching signal generated in accordance with the switching operation of the display content switching means to the key matrix switching control section, the display switching control section, and the output signal switching control section. The display content switching means recognizes a microphone and the voice inputted from the microphone, and outputs the switching signal corresponding to the voice. The present invention provides a remote control transmitter configured with a voice recognition circuit. The present invention also provides a remote control transmitter that is provided with a switch means for turning on and off the microphone.

[0006]

[Operation] Therefore, according to the present invention, simply by saying the desired electronic device into the microphone, a command corresponding to the desired electronic device can be displayed on the display, and unlike the conventional method, it is possible to obtain commands corresponding to the desired electronic device. No need to preset. In addition, since the microphone is turned on and off by a switch, there is no risk of malfunction due to external noise coming in except when necessary.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an external perspective view showing an embodiment of a remote control transmitter according to the present invention, and FIG. 2 is an internal electrical circuit diagram thereof.

First, the electrical circuit of the remote control transmitter of the present invention will be explained with reference to FIG. In this figure, parts that are the same as those in the prior art are designated by the same reference numerals.

Therefore, 3 is a display switching control section, 4 is a display section, 5 is a key matrix switching control section, 6 is a key matrix, 7 is a key input determination section, 8 is an output signal switching control section, 9 is an output section, 10 is a memory. In this figure, the parts that characterize the present invention are the microphones and voice recognition section indicated by numerals 1 and 2, and a switch 12 provided between them.

These replace the conventional changeover switch 11, and when the user speaks the name of the desired electronic device into the microphone 1, the voice input from the microphone 1 is recognized by the next stage voice recognition section 2. It is designed to recognize this and output a switching signal corresponding to the voice, thereby operating the display switching control section 3, key matrix switching control section 5, and output signal switching control section 8, respectively. Further, the switch 12 is a normally open switch, and is manually turned on only when inputting audio from the microphone 1.

An external view of the remote control transmitter according to the present invention has the configuration shown in FIG.
A microphone 1, a switch 12 for turning it on and off, and a display section 4 are provided.

To explain the remote control transmitter of the present invention having the above configuration in a little more detail, the key matrix 6 has 64 keys on one side, which can be switched to four sides, that is, 64×4=256 keys, each of which has 64 keys. K0 on the key
A key number of ~K255 is assigned. The memory 10 has 256 types of command data assigned to each manufacturer in correspondence with each key number, and further supports commands from 12 manufacturers. That is, 2
56×12=3072 command data are stored. The operation will be explained below along with the operating procedure. As an example, assume that you press the power button on a Sharp TV.

[0013] The operator speaks ``Sharp TV'' into the remote control. Voice is input through the microphone 1 and converted into an electrical signal. This audio signal is sent to the audio recognition section 2, where it is recognized. When recognized, a signal indicating "Sharp TV" is sent to the display switching control section 3, key matrix switching control section 5, and output signal switching control section 8.

The display switching control section 3 displays the display section as shown in FIG. 3 in response to the received signal. Further, the key matrix switching control section switches the matrix 6 so that the key number (key state) corresponds to "television". On the other hand, the output signal switching control section 8 stores the key number K0 in the memory 10.
~ Assign "sharp" command data to K255.

When the operator presses the "power" key (K25) on which the command is displayed, the key input determination section 7 determines this, and the output signal switching control section 8 selects the key to which "power" is assigned. Command to output number signal. In response, the output signal switching control section 8 selects "
The command data assigned to the key number of "power supply" is called up and sent to the output section 9. The output unit 9 emits an infrared LED according to this command data. That is, it outputs a command signal.

[0016]

[Effects of the Invention] Since the present invention is configured as described above, the display content can be changed simply by saying the desired display content on the display section using a microphone, making it a very convenient remote control transmitter. can be provided.

Furthermore, in the present invention, since the microphone is turned on and off by a switch, malfunctions can be prevented.
