Abstract

To provide a center pickup type speaker system which emphasizes sound on the center side with a stereo playback speaker system, mimics the sound heard in the front row of a concert hall, and allows you to enjoy music even at a low volume.SOLUTION: A center pickup type speaker system has a structure in which, for listeners (people) who listen to music, sound of a speaker unit 5 in stereo reproduction is reflected by reflectors 1, 2, and 3 consisting of top and bottom and side surfaces in three directions as shown in FIG. 1. When the vertices 6 of side reflectors 3 of a left speaker system 7 and a right speaker system are aligned and the angle of the side reflector 3 is adjusted, the sound on the center side is emphasized and the surrounding sound is reduced.SELECTED DRAWING: Figure 1

Description

Field of technology

  This invention is a system in which when a music is reproduced by a stereo reproduction speaker system, the sound heard on the center side is emphasized and the music can be enjoyed even at a low volume.

  Until now, stereo playback speaker systems have aimed to reproduce the sound heard around the center of the concert hall.

None

Conventional stereo playback speaker systems have aimed to reproduce the sound heard near the center of the concert hall, but this method is suitable for orchestra such as classical music, but it is unsatisfactory in sound quality in pop rock jazz etc. When the music was felt and the volume was raised, the noise problem was developed and annoyed to the family and neighbors.
In order to enjoy music even at a low volume, if you can emphasize the sound on the center side with the stereo playback speaker system, you can enjoy the music even if you do not raise the volume, close to the sound heard in the front row of the concert hall.

With respect to a listener (person) who listens to music, the sound of the speaker unit 5 in stereo reproduction is all reflected by a reflector consisting of three directions of upper and lower sides as shown in FIG.
When the vertices 6 of the left and right speaker system side reflectors 3 are aligned as shown in FIG. 3 and the angle of the side reflectors 3 is adjusted, the sound on the center side is emphasized and the surrounding sound is reduced.

  Although the sound quality was unsatisfactory, if the sound could be emphasized toward the center side, it would be closer to the sound heard in the front row of the concert hall, and you could enjoy music even at a low volume.

It is an elevation view of a left speaker system. It is the sectional view on the AA line of FIG. It is a use condition diagram which put together the apex parts of the left and right speaker systems.

Structure description

Modes for carrying out the present invention will be described.
The center pickup type speaker system has the same structure as the left and right speaker systems, and is composed of a cabinet 4 in which a speaker unit 5 is housed and a reflector plate in front of the speaker unit 5 which is composed of three directions, that is, an upper side, a lower side, and a side. ing.
As shown in FIG. 2, the speaker unit 5 is mounted sideways without facing the front, faces the side reflector 3, and the side reflector 3 is obliquely attached.
Match the vertices 6 of the side reflectors 3 of the left and right speaker systems as shown in FIG. 3, and the angle 9 at which the side reflectors 3 are tilted is such that the center sound can be emphasized based on about 45 degrees as shown in FIG. Adjust (directivity of reproduced sound becomes sharp).
As shown in FIG. 2, the apex 6 of the side reflector 3 protrudes in front of the aperture of the speaker unit 5.
A center pickup type speaker system is a state in which the vertices 6 of the side reflectors 3 of the left and right speaker systems are aligned as shown in FIG.
By attaching the upper and lower reflectors and the side reflectors to the ordinary speaker system and aligning the vertices 6 of the side reflectors 3, the center sound is emphasized and the center pickup system is realized.
If the inclination angle of the side reflector 3 is determined, the side reflector 3 can be produced by integrating the right and left sides.

The invention's effect

Characteristic

When a listener (person) listens to music with the apex 6 of the side reflector 3 aligned, the sound is emphasized toward the center and approaches the sound heard in the front row of the concert hall.
If the position where you listen to music is closer to the speaker system, the center sound will be further emphasized.
When the apex 6 of the left and right speaker system side reflectors 3 is separated and the space is widened, the sound on the center side is weakened and normal stereo reproduction is performed.
As for the reflector, if the side reflectors are provided even if the upper and lower reflectors are eliminated, the sound at the center can be emphasized even if it is weakened.
When listening to music with the center pickup method, it can be confirmed that the center sound is emphasized and the surrounding sound is reduced.
A person with a deafness in one ear can enjoy music as much as a normal person, because the center sound is emphasized compared to normal stereo reproduction with the center pickup method.

Claims (1)

The structure of the center pickup type speaker system is such that all the sound of the speaker unit 5 is reflected by a reflecting plate composed of three directions, that is, upper and lower sides and side surfaces.
The center pickup type speaker system can emphasize the sound on the center side by aligning the vertices 6 of the left and right speaker system side reflectors 3.
