Description

Remote location notification device using a microphone

The present invention relates to a location notification device of a remote control using a microphone, in particular, by picking up the ambient sound using a microphone to automatically alert the user when the picked up ambient sound is more than a predetermined criterion to recognize the position of the remote control to the user The present invention relates to a remote location notification device using a microphone.

In general, it is difficult to have all these keys on the front of the main body of the home appliance because of the increasing number of keys for using the functions due to the variety of home appliance functions. In order to eliminate the inconvenience of having to operate in close proximity to the equipment, a remote controller (Remote Controller: commonly referred to as a Remocon) that allows key input wirelessly from a remote place is widely used.

The operation of the remote controller will be described in detail. As shown in a block diagram of a conventional remote controller and a home appliance of FIG. 1, the remote controller 100 includes a key input unit 110, a control unit 120, and a transmission unit 130. The home appliance 200 (in a preferred embodiment of the present invention, a television) includes a receiver 210, a signal processor 220, a controller 230, and a driver 240.

In the drawing, when the remote controller 100 receives a predetermined key signal corresponding to a user's key operation from the key input unit 110 having a plurality of keys for performing a plurality of functions, the controller 120 controls the controller 120. ) Applies key data corresponding to the applied key signal to the transmitter 130.

At this time, the transmitter 130 is modulated by a predetermined infrared carrier based on the key data from the controller 120 and transmitted through the infrared light emitting diode, and the receiver 210 of the home appliance 200 is a transmitter of the remote controller 100. Receives the infrared carrier from the 130 through the photodiode and the received electrical signal is applied to the signal processor 220, and amplifies, detects and waveforms the electrical signal applied from the signal processor 220 to perform key data. Is applied to the controller 230.

Then, the controller 230 controls the driver 240 based on the key data applied from the signal processor 220 to drive the corresponding operation, thereby controlling the operation of the home appliance remotely.

However, such a remote control has a problem that the family members are commonly used in the house, and thus the position of the remote control is used differently so that the user cannot remember the position of the remote control. There was an uncomfortable problem that it takes a long time to find a remote control.

Meanwhile, in order to solve the above problem, when the remote control is called by a radio frequency (RF) signal from a home appliance, the remote control receives this call to generate an alarm sound to confirm the position of the remote control to the user. There was a cumbersome problem of having to make a call by approaching a home appliance near one by one, and the manufacturing cost increased due to RF transmission and reception.

Therefore, the present invention has been sought to find a way to identify the place where the remote control is located by simply generating a momentary sound, such as clapping anywhere in the user without limiting the location.

The purpose of the present invention is to detect the sound by using a microphone when the user generates a momentary sound such as clapping, and automatically detects the position of the remote control by generating an alarm sound when the detected sound is above a predetermined standard. It is to provide a location notification device of the remote control using a microphone to give.

In the remote control device using a microphone according to the present invention, a remote control device for transmitting a key data corresponding to a user's key operation on an infrared carrier, and is driven based on battery power to pick up sounds around the remote control. A microphone unit for outputting a first drive signal when the amplified signal is amplified or higher than a predetermined level, a timer unit driven based on the first drive signal, and outputting a second drive signal for a predetermined time; It is characterized in that it further comprises an alarm sound generating unit for driving based on the alarm sound for a predetermined time.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a position notification device of a remote controller using a microphone according to a preferred embodiment of the present invention, and includes a microphone unit 10, a timer unit 20, and an alarm sound generator 30.

In this configuration, a battery BATT for supplying predetermined power and a switch SW for selectively supplying / blocking the predetermined power from the battery BATT to the microphone unit 10 based on a user's switching operation are included. In order to prevent power consumption of the battery BATT, the user may control the driving of the microphone 10 at all times.

The microphone unit 10 is driven by a microphone installed on one side of the remote controller based on a predetermined power source from the battery BATT transmitted through the switch SW, and amplifies the sound picked up through the microphone. The amplified sound is compared with the preset reference sound, and if the picked up sound is greater than the reference sound, the first driving signal is applied to the timer unit 20.

On the other hand, the timer unit 20 starts counting based on the first driving signal from the microphone unit 10, counts a predetermined time enough to allow the user to check the position of the remote controller, and generates a second driving signal for a predetermined time. Output

In addition, the alarm sound generator 30 drives a buzzer or a speaker based on the second drive signal from the timer 20 to generate a predetermined alarm sound for the user to recognize the position of the remote controller.

Next, the operation process of the position notification device of the remote control using the microphone according to the preferred embodiment of the present invention including the above-described configuration will be described in detail.

First, when the switch SW is turned on so that the user can check the position of the remote controller through sound detection, predetermined power from the battery BATT is applied to the microphone unit 10.

Then, the microphone unit 10, which receives the predetermined power, starts to detect the sound around the remote controller.

At this time, when the user generates a clapping sound to check the position of the remote control, the microphone unit 10 detects this, that is, when the picked up sound of the clapping sound is greater than the preset reference sound, the first driving signal includes a timer unit ( 20).

Then, the timer unit 20 applies the second driving signal to the alarm sound generating unit 30 for a predetermined time set based on the first driving signal, that is, a time sufficient for the user to check the position of the remote controller. .

Then, the alarm sound generator 30 receiving the second driving signal for a predetermined time from the timer unit 20 generates an alarm sound through a buzzer or a speaker to recognize the current position of the remote controller.

On the other hand, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention.

As described above, according to the present invention, there is an effect of providing the convenience of recognizing the location of the remote control, which is easy to forget, by automatically generating an alarm sound by detecting a sound generated by the user at the remote control itself.
