Description

Speaker optimal position display device of audio system {APPARATUS FOR DISPLAYING FITTING POSITION OF SPEAKER IN AUDIO SYSTEM}

The present invention relates to an audio system, and more particularly, to an apparatus for optimally displaying a speaker of an audio system, which provides information for locating each speaker to an optimized position in a multichannel audio system of 5.1 channels or more.

In recent years, audio systems are moving away from general stereo systems and are becoming multimedia as computers, DVD players, and home theaters are combined. It is coming true.

The 5.1-channel audio system is equipped with a center woofer (CS), front left and right speakers (FL, FR), and rear left and right speakers (RL, RR) in addition to the woofer. You need to place them in place.

However, conventionally, the user had to check the location of each speaker while listening to audio.

In other words, in order to have an optimal surround environment, each speaker should be placed at an appropriate position. This problem has been raised because it is very subjective, difficult to place accurately and quickly, because the process depends only on human hearing.

The present invention has been implemented to solve the above-described problems of the prior art, the speaker optimum position of the audio system to display the optimized position between the remote control and the speaker by measuring the sound pressure of the natural frequency band output from each speaker through the user remote control It is an object to provide a display device.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a layout diagram of an audio system according to the present invention, for example, a 5.1-channel audio system, which includes a main audio 100, a center speaker (CS: 202), a woofer (SU: 204), and a front left speaker (FL: 206). ), The front right speaker (FR: 208), the rear left speaker (RL: 210), the rear right speaker (RR: 212), and the remote control 300.

In the present invention, the sound signal output from the CS (202), SU (204), FL (206), FR (208), RL (210), RR (212) is received from the remote control unit 300, and the measured sound pressure data The current position input value and the reference value (optimized position input value) are compared to implement the difference value to be displayed on the display panel of the remote controller 300 or the main audio 100.

To this end, according to the present invention, the input / output difference values are displayed in the first and second embodiments according to whether they are displayed on the main audio 100 or directly on the remote controller 300.

First, FIG. 2 is a first embodiment according to the present invention, in which a sound pressure measuring unit 32 and a transmitter 34 are provided in a remote controller 300, and a receiver 12 and a controller 14 are provided in the main audio 100. The memory unit 16 and the display unit 18 are provided respectively.

The sound pressure measuring unit 32 performs a function of measuring speaker sound pressure data transmitted from the CS 202, the SU 204, the FL 206, the FR 208, the RL 210, and the RR 212. The measured sound pressure data is received by the transmitter 34 in the receiver 12 in the main audio 100.

The receiver 12 in the main audio 100 provides sound pressure data provided from the remote controller 300 to the controller 14.

The controller 14 compares the sound pressure data of each of these speakers 202, 204, 206, 208, 210, and 212, that is, the current position measurement data and the optimized position data stored in the memory unit 16, and compares the difference value. The display unit 18, for example, controls to display on the LCD panel. For example, these data are shown in Table 1 below.

TABLE 1

CS SU FR FL RL RR Speaker output 100 Hz 100 Hz 100 Hz 100 Hz 100 Hz 100 Hz Optimization location data 25 dB 45 dB 25 dB 35 dB 45 dB 25 dB Current position measurement data 45 dB 45 dB 25 dB 45 dB 30 dB 30 dB I / O difference 20 0 0 10 -15 5

As shown in Table 1, the CS 202, the FL 206, and the RR 212 have positive input / output difference values, so the speaker output needs to be lowered or the speaker's position should be far from the user. There is. In addition, since the RL 210 has a negative input / output difference value, it is necessary to increase the speaker output or place the speaker closer.

SU 204 and FR 208 may find that their location is optimized.

3 is a second embodiment according to the present invention, the sound pressure measuring unit 36, the control unit 38, the memory unit 40, the display unit 42 is provided in the remote control 300. That is, the second embodiment is characterized in that the remote controller itself measures the sound pressure value, compares the measured data with the preset data, and displays the difference value on the display unit 42.

This second embodiment can directly display the position value of the speaker through the LCD panel on the remote control 300, it will be readily understood that the data transmission / reception process with the main audio 100 can be omitted. .

On the other hand, the sound pressure data measurement technique applied to the present invention is a technique for analyzing the sound spectrum, compared to the technique of sequentially checking and displaying the value output from each speaker (202, 204, 206, 208, 210, 212) Measurement time can be shortened. That is, each speaker 202, 204, 206 is allocated to each speaker 202, 204, 206, 208, 210, 212 by assigning a sound signal in a natural frequency range and analyzing the dB measurement value of the sound spectrum transmitted to the remote controller 300. , 208, 210, and 212 can simultaneously measure and analyze the output values, so that the user can recognize the current speaker position in a short time.

According to the present invention, it is possible for a user to increase the satisfaction level of an audio system using a multi-channel speaker, and to build a system environment objectively rather than directly selecting a speaker position based only on the user's ear.

As mentioned above, although this invention was concretely demonstrated based on the Example, this invention is not limited to this Example, Of course, various changes are possible within the range which does not deviate from the summary.
