Description

Apparatus And Method Compensating Strength Of BEEP Signal In Input Device Of Amp}

The present invention relates to an apparatus and method for correcting the strength of a beep signal, and more particularly, to an apparatus and method for preventing a phenomenon in which the strength of a beep signal is attenuated due to a mute signal at an amplifier input terminal.

In general, the amplifier receives and outputs an audio signal input through a signal input terminal. In addition, F receives and outputs a beep signal in addition to a voice signal, and also receives a mute signal to prevent unnecessary noise during power on and off.

However, when a mute signal and a beep signal are input at the same time, for example, when the user presses the seek button for a long time to find a station to listen to, a beep signal is output and mute to reduce noise (while searching for a station). When the two output signals are simultaneously input to the amplifier, the intensity of the beep signal is attenuated by the input mute signal so that the user can output the beep even if the amplifier outputs a beep signal. You may have trouble hearing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide an apparatus and a method for compensating a beep signal strength at an input terminal for preventing the strength of the beep signal from being attenuated by the mute signal.

In order to achieve the above object, an apparatus for correcting the strength of the beep signal at the amplifier input terminal according to an aspect of the present invention includes a beep resistor and a mute resistor, and when the control signal is input, connects the beep resistor and the mute resistor A beep signal output unit configured to output a beep signal through a connected resistor; And a controller configured to output the control signal to connect the beep resistor and the mute resistor when a mute signal is input.

According to another aspect of the present invention, a method for correcting the strength of a beep signal through a beep resistor and a mute resistor at an amplifier input stage includes: outputting a control signal for connecting the beep resistor and the mute resistor when a mute signal is input; And connecting the beep resistor and the mute resistor when the control signal is input, and outputting the beep signal through the connected resistor.

According to the present invention, there is an effect that the beep signal can be output at a constant intensity without being affected by the mute signal.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. And is intended to enable a person skilled in the art to readily understand the scope of the invention, and the invention is defined by the claims. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. It is noted that " comprises, " or "comprising," as used herein, means the presence or absence of one or more other components, steps, operations, and / Do not exclude the addition.

Hereinafter, a beep signal strength correcting apparatus at an amplifier input terminal according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. 1 is a block diagram illustrating an apparatus for compensating a beep signal strength at an amplifier input terminal according to an embodiment of the present invention, and FIG. 2 is a circuit diagram of FIG. 1.

As shown in FIG. 1, the beep signal strength apparatus 100 of the present invention includes a beep signal output unit 110 and a controller 120.

As shown in FIG. 2, the beep signal output unit 110 includes a beep resistor R1 and a mute resistor R2. When the control signal is input from the control unit 120, the beep resistor R1 and the mute resistor ( R2) is connected and a beep signal is output through the connected resistor. For example, the beep signal output unit 110 outputs a beep signal when the seek button is operated by a user who wants to listen to radio or watch TV. When the control signal is input when the beep signal is output, the beep signal output unit 110 connects the beep resistor R1 and the mute resistor R2 and outputs a beep signal through the connected resistor. If the control signal is not input, the beep resistor R1 and the mute resistor R2 are disconnected, and the beep signal is output through the beep resistor R1.

The beep signal output unit 110 is connected in parallel when the beep resistor R1 and the mute resistor R2 are connected. As such, when the control signal is input, the beep signal output unit 110 connects the beep resistor R1 and the mute resistor R2 in parallel to lower the resistance value to output the strength of the beep signal through the beep resistor R1. Increased output than usual.

The controller 120 receives the beep signal output from the beep signal output unit 110 and outputs it to the amplifier input unit 150, and receives the audio signal output from the voice signal output unit 130 to the amplifier input unit 150. Output

In addition, the controller 120 prevents unnecessary noise from being output through the amplifier when the mute signal is input from the mute signal output unit 140. That is, when the mute signal is input, the controller 120 removes the noise when the beep signal is output.

For example, a Seek button is operated by a user who wants to listen to a radio broadcast, and a beep signal is output from the beep signal output unit 110. In this case, the mute signal output unit 140 outputs a mute signal to remove noise. . As such, when the control unit 120 receives a mute signal from the beep signal output unit 110 and a mute signal for noise removal from the mute signal output unit 140, the strength of the beep signal is attenuated by the mute signal. To prevent this, a control signal for connecting the beep resistor (R1) and the mute resistor (R2) is output. If the mute signal is not input, the control signal is not output.

As described above, when the control unit 120 outputs a control signal, the beep signal output unit 110 connects the beep resistor (R1) and the mute resistor (R2) in accordance with the input control signal to lower the resistance value, the resistance Output a beep signal through the lowered resistor. That is, the beep signal output unit 110 increases and outputs the strength of the beep signal in preparation for the strength of the beep signal being attenuated by the mute signal. Therefore, the same signal strength as the beep signal output through the mute resistor R1 may be maintained.

1 and 2, the beep signal strength correction apparatus has been described in the amplifier input terminal according to an embodiment of the present invention. Hereinafter, the beep signal in the amplifier input terminal according to an embodiment of the present invention will be described with reference to FIG. 3. The intensity correction method will be described. 3 is a flowchart illustrating a beep signal strength correction method at an amplifier input terminal according to an embodiment of the present invention.

As shown in Figure 3, it is checked whether the mute signal is input (S300).

If the mute signal is input, the control signal is output (S310). If the mute signal is not input, the control signal is not output (S320).

Check whether the control signal is input (S330).

As a result, when the control signal is input, the beep resistor R1 and the mute resistor R2 are connected in parallel (S340), and the beep signal is output through the parallel connected resistor (S350).

However, as a result of the check, if the control signal is not input, the beep resistor R1 and the mute resistor R2 are disconnected, and the beep signal is output through the beep resistor R1 (S370).

Although the configuration of the present invention has been described in detail with reference to the preferred embodiments and the accompanying drawings, this is only an example, and various modifications are possible within the scope without departing from the spirit of the present invention. Therefore, the scope of the present invention should not be limited by the illustrated embodiments, but should be determined by the scope of the appended claims and equivalents thereof.
