Description

{OMNIDIRECTIONAL SPEAKER COMBINED LUMINAIRES}

The present invention relates to a non-directional loudspeaker for a luminaire, and more particularly to a luminaireless non-directional loudspeaker capable of emitting a sound source in all directions and capable of providing LED illumination.

Generally, to listen to a sound source, a sound output device such as CDP (Compact Disk Player) or MP3 is used. Digital information obtained from the CDP of the sound source output device detects a signal from a light beam reflected by a laser irradiated from the optical pickup device and amplifies the detected signal to change it to a combination of 0 and 1 as a digital signal, Converter or the like, and is transmitted to the amplifier so that it is provided as a sound source that can be heard by the user.

At this time, finally, the sound is reproduced by using the loudspeaker. The vibration of the vibrator incorporated in the loudspeaker meets the air fluid in the front and rear direction, and the sound is emitted to the outside through the air.

Such a speaker has been developed for a long time by various structures and methods. However, since it has a directivity characteristic, it can not obtain a proper position if only one is provided, and it is provided with two or more, Can be obtained.

In addition, a conventional speaker is coupled to one side of a speaker's external body in one direction. In order to obtain a wide directivity angle, a plurality of speakers having different directions must be installed. And the like.

In order to solve this problem, there has been proposed a method of finding a non-direction by providing a reflector on the upper part of a speaker. However, since the provision of non-direction is limited due to the reflection angle of such a reflector, 360 degree non-direction in practical sense can not be realized, The sound source is not emitting.
