Description

Sound transmission method for tracking the movement of an object using a directional speaker and apparatus using the same

The present invention relates to a sound transmission method for tracking a movement of an object using a directional speaker, and more particularly, to a method and an apparatus capable of delivering continuous sound to an object while tracking a moving object.

In general, a speaker converts an electrical signal into vibration and transmits the same to air to generate sound. Such speakers have isotropy when transmitting vibrations in the air. Accordingly, the listener can hear sound generated from the speaker in all directions with respect to the speaker. The isotropy of these speakers sometimes leads to unnecessary problems. For example, if various works or exhibits such as an art gallery or a museum are installed, and the installation is designed to explain descriptions of the works and exhibits through speakers, the spaces generated by the speakers due to the narrow spaces of the museums and museums Interference occurs between sounds.

In addition, if a large number of people simultaneously listen to descriptions of different works and exhibits from the speaker, a large amount of voice guidance interferes with each other and distorts each other, resulting in tremendous noise. In order to solve this problem, a super-directional speaker has been introduced that can play sound only in a specific direction.

A superdirectional speaker is a speaker that modulates a sound signal and puts it on an ultrasonic signal so that the sound signal has the superdirectional characteristic of ultrasonic waves. The super directional speaker has low sound quality due to low frequency while no sound quality decrease due to high frequency and can easily generate the entire audible sound range, and has a very high directivity in a specific direction. There is no limit, and since an enclosure (speaker case) is unnecessary as a speaker system, there is an advantage that the sound quality can be improved, the band characteristic can be improved, and the efficiency can be improved as compared with the conventional speaker system.
