It relates to a remote control device.

Recently, in line with the trend of increasing functions of home appliances, remote control systems, which have been applied to expensive devices in the past, have been extended to extremely general home appliances in recent years. The main components of the remote controller used for the control are shown.

It is a battery.

In addition, the reference numeral LED is a light emitting diode which is driven by the power supplied from the battery (BAT.) And outputs an infrared signal for the user's key selection, and the reference numeral Q is output from a predetermined terminal of the remote control IC (2). The transistor is turned on / off based on a code signal to interrupt an operating current applied to the LED.

That is, the remote control device having the above-described configuration has an LED driving unit (2) based on the code data corresponding to the key input of the remote control IC (2) for the user's key input through the key matrix circuit (1). The LED is operated by driving on / off the transistor Q provided in 4). As a result, the infrared signal corresponding to the key input of the user is outputted from the LED to the main body side.

On the other hand, in recent years, most of the home appliances that are on the market are quite diverse and complicated, so it is inconvenient for the first user to operate the device. Furthermore, in the case of the visually impaired, it is displayed on each button key of the remote control device. I could not check the numbers or letters that existed, so there was a problem with the device.

The present invention has been made in view of the above circumstances, and when the user selects a random button key, the voice of the selected contents which can guide the user to the operation contents to be executed as the corresponding button key is selected by voice. The purpose is to provide a remote control device with a function.

According to the present invention for realizing the above object, a remote control device having a voice guidance function for selection is output from a key matrix circuit and a key matrix circuit for outputting a predetermined key input signal corresponding to a button key selected for a user's key selection. A remote control apparatus having a control unit for outputting a corresponding code signal corresponding to a key signal, the remote control apparatus comprising: a voice message storage unit having function information for each button key stored as predetermined voice data, and according to a code signal from the control unit; A digital signal processing unit for reading out the voice guidance message stored in the voice message storage unit and processing the data as data suitable for reproduction output. A decoder for decoding and outputting voice data output from the digital signal processing unit. Synthesizes voice messages based on analog signals Including pyx part, the amplification unit for amplifying the audio signal outputted from the audio synthesis unit to a predetermined level, and an audio output unit for outputting the voice guidance messages for audible sound according to the amplified negative signal output characterized in that configured.

That is, according to the present invention having the above-described configuration, the control unit outputs a code signal corresponding to the key input with respect to the user's key input. The digital signal processor is configured to output the code signal from the voice message storage unit based on the code signal. The voice message data is read.

The read voice message data is decoded into an analog signal by the decoder, and then synthesized into a voice message to be guided to the user while passing through the voice synthesizer. The synthesized voice message is amplified to a predetermined level by the amplifier and a speaker. It is output in the audible state through the voice output unit such as.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention.

FIG. 2 is a block diagram of a remote control device having a voice prompt function for selecting contents according to an embodiment of the present invention, in which components that perform the same functions as those shown in FIG. Will be omitted.

In FIG. 2, reference numeral 4 denotes a voice message storing unit in which function information for each button key of the remote control unit is stored as predetermined voice data, and 5 denotes the voice message storing unit according to a control signal from the remote controller IC 2; A digital signal processor (DSP) that reads out the voice guidance message stored in (4) and processes it as data suitable for reproduction output, and 6 uses the voice data output from the digital signal processing processor (5). Codec (coder-decoder) to decode and output.

Reference numeral 7 denotes a voice synthesizer for synthesizing a voice message on the basis of an analog signal decoded and output by the codec 6, and 8 denotes a voice signal output from the voice synthesizer 7; The amplifier for amplifying to a predetermined level, SP is a speaker for outputting an audible voice guidance message in accordance with the output signal of the amplifier 8.
