Abstract

The present invention relates to a multi-speaker, and more particularly, to a multi-speaker which includes a first speaker unit for outputting sound, a second speaker unit for outputting a supergain sound of an audible frequency band, And a control unit for controlling the output of sound to any one or more of the plurality of output units.
According to the present invention as described above, it is possible to output not only high-pitched sound, medium-pitched sound and low-pitched sound, but also super-directional sound of an audible frequency band.

Description

Multi-speaker {Multi-speaker}

More particularly, the present invention relates to a loudspeaker, and more particularly, to a loudspeaker which outputs not only treble, mid and low bass but also a supergiant sound capable of transmitting sound to a specific object located at a certain distance, And more particularly,

Generally, a speaker converts an electric signal into vibration and transmits it to the air to generate sound, which is isotropic when transmitting vibration in the air.

Thus, the listener can hear the sound generated from the speaker in all directions with respect to the speaker.

However, the isotropy of a speaker often causes unnecessary problems.

For example, if a variety of works or exhibits such as a museum or a museum are installed and the installation is designed to explain the description of each work and the exhibits through a speaker, Interference occurs between sounds.

Also, if a large number of people simultaneously hear a description of different works and exhibits from a speaker, a large amount of voice guidance is interfered with and distorted from each other, resulting in a large noise.

In order to solve this problem, a super directional speaker which can reproduce a sound in a specific direction has emerged.

Conventionally, a super-directional speaker is composed of an ultrasonic transducer model for filtering an ultrasonic wave, an ultrasonic amplifier for amplifying a filtering signal, and an ultrasonic transducer for converting an amplified signal into an ultrasonic signal, as disclosed in Patent Document 10-0622078, Can be output.

However, the super-directional speaker can reproduce medium and low frequencies, but the effect is weak.

Accordingly, there is a desperate need to develop a technology that can enhance the sound transmission effect by outputting high, mid, low, and supergiant sounds together.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a speaker apparatus, a speaker apparatus, And a control unit for controlling the output of sound to at least one of the speaker units, thereby outputting sounds at a high frequency, a middle frequency, and a low frequency, as well as outputting a supergiant sound in an audible frequency band. It is an object to provide a multi-speaker.

According to an aspect of the present invention, there is provided a speaker apparatus including a first speaker unit for outputting sound, a second speaker unit for outputting a supergain sound in an audible frequency band, and a speaker unit And a control unit for controlling the output of the sound.

Preferably, the first speaker unit includes a treble output unit for outputting a treble, a mid-tone output unit for outputting a middle tone, and a bass output unit for outputting a low tone.

The second speaker unit is located at one or more of upper, lower, right, and left sides of the first speaker unit, and is rotatably mounted on the first speaker unit.

In addition, a driving unit may be further provided to adjust the direction of supergain output by rotating the second speaker unit.

The driving unit includes a rotating shaft provided in the second speaker unit, a bearing for rotatably mounting the rotating shaft on the first speaker unit, and a driving motor for rotating the rotating shaft.

In addition, the second speaker unit further includes a sensing sensor, and the control unit receives the sensing signal of the sensing sensor with respect to the moving person to control the driving motor, so that the output direction of the supergain sound is controlled.

As described above, according to the multi-speaker of the present invention, it is possible to output not only high-pitched sound, medium-pitched sound and low-pitched sound, but also supergain sound of an audible frequency band together, It is a useful and effective invention.

1 is a view showing a multi-speaker according to the present invention,
2 is a view showing an operating state of the multi-speaker according to the present invention,
3 is a view illustrating a driving unit of a multi-speaker according to the present invention,
4 is a view showing a state where a multi-speaker according to the present invention is further provided with a detection sensor.

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

It should be noted that the present invention is not limited to the scope of the present invention but is only illustrative and various modifications are possible within the scope of the present invention.

FIG. 1 is a view showing a multi-speaker according to the present invention, FIG. 2 is a view showing an operating state of a multi-speaker according to the present invention, FIG. 3 is a view showing a driving unit of a multi- 4 is a view showing a state where a multi-speaker according to the present invention is further provided with a detection sensor.

As shown in the figure, the multi-speaker 10 includes a first speaker unit 100, a second speaker unit 200, and a controller 300.

The first speaker unit 100 is provided for outputting sound and the second speaker unit 200 is provided for outputting a supergative sound.

It is natural that the first speaker unit 100 and the second speaker unit 200 output sound in a range of the audible frequency band.

The control unit 300 controls the first speaker unit 100 and the second speaker unit 200 to output sound.

Here, the first speaker unit 100 includes a treble output unit 110 for outputting treble, a mid-tone output unit 120 for outputting a middle tone, and a bass output unit 130 for outputting a low tone.

Accordingly, not only the high, middle, and low sounds output from the first speaker unit 100 but also the supergative sound output by the second speaker unit 200 can be output together with the sound output to the user. It can be conveyed more clearly.

The supergain sound output from the second speaker unit 200 outputs a sound to the ultrasonic waves. When the listener is positioned on the line that outputs the supergiant sound, the sound is heard.

To this end, the second speaker unit 200 is positioned at one or more of upper, lower, right, and left sides of the first speaker unit 100 and is rotatably mounted on the first speaker unit 100.

2, the second speaker unit 200 is disposed on the upper side of the first speaker unit 100 and is rotatable in the horizontal direction, so that the second speaker unit 200 can be rotated in the horizontal direction, And outputs sound.

The second speaker unit 200 may further include a driving unit 300 for adjusting the direction of supergain output.

As shown in FIG. 3, the driving unit 400 includes a rotating shaft 410, a bearing 420, and a driving motor 430.

The rotary shaft 410 is provided in the second speaker unit 200 and the bearing 420 is provided to allow the rotary shaft 410 to be rotatably installed in the first speaker unit 100.

The driving motor 430 is provided to rotate the rotating shaft 410. The rotating force generated by the driving motor 430 is transmitted to the rotating shaft 410 to rotate the second speaker unit 200, As shown in Fig.

As shown in FIG. 4, the second speaker unit 200 further includes a sensing sensor 500.

The detection sensor 500 controls the driving motor 430 by receiving the detection signal for the moving person from the control unit 300, thereby controlling the output direction of the supergain sound.

In other words, the output direction of the supergiant sound is controlled to be rotated along the moving person.

For this purpose, it is preferable that the sensing direction of the sensing sensor 500 be positioned in the same or parallel to the direction of the supergain sound output of the second speaker unit 200.
