[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speaker system in which speakers are arranged on the front and top sides of a cabinet and a conical reflector is arranged so as to face the speakers on the top side. The present invention relates to a loudspeaker system which can select between omnidirectional and omnidirectional and can reproduce surround sound and heavy bass.

[0002]

2. Description of the Related Art As an example of a conventional omnidirectional speaker,
As shown in FIG. 3, a bass speaker 22 is provided on the front 21a side.
Is mounted on the upper surface 21b side of the cabinet 21 to which the loudspeaker is attached, and a flat plate 24 is mounted at an appropriate interval in parallel with the upper surface 21b, and the flat plate 24 has a cone having a vertical angle perpendicular to the cross section. There is a speaker device in which a reflection plate 25 is attached to face the high-frequency speaker 23 so as to be non-directional in a plane.

[0003]

However, in the speaker system shown in FIG. 3, only the non-directional speaker can be used, and there is a disadvantage of lack of versatility.

An object of the present invention is to solve the above-mentioned drawbacks of the conventional omnidirectional speaker and to provide a speaker system capable of selecting omnidirectionality and directivity.

[0005]

The loudspeaker system of the present invention is a loudspeaker system in which loudspeakers are arranged on the front side and the upper side of a cabinet, and a conical reflector is arranged so as to face the loudspeaker on the upper side. A first speaker for low-pitched sound and a second speaker for high-pitched sound are arranged on the front side of the cabinet, and an empty room is defined by a partition plate at the top of the cabinet, and the empty room and the outside are ducted. A third speaker connected to the cabinet and having the cavity as a cavity is disposed on the upper surface side of the cabinet.
The lower housing is formed in a conical shape using the speaker of the above, and this housing is arranged so as to face the third speaker, and the diffuser is arranged above so as to face the fourth speaker. Configuration. Then, the conical reflector is supported by a plurality of pillars projecting obliquely from the upper surface of the cabinet. When the conical reflector is constituted by the fourth speaker and the diffuser, the diffuser is inclined obliquely from the upper surface of the cabinet. The fourth speaker is supported by the plurality of projecting columns and the fourth speaker is supported by the diffuser in a suspended state.

[0006]

A vacant space defined by a partition plate is provided at the upper part of the cabinet, and the vacant space communicates with the outside by a duct. A third speaker having the vacant space as a cavity is disposed on the upper surface side of the cabinet. And a conical reflector on the front side of the cabinet, the third speaker becomes non-directional, and different audio signals can be input to the first to third speakers. When normal stereo reproduction is performed by the first and second speakers, the third speaker is a surround speaker.
When the third speaker is used for normal stereo reproduction, the first speaker on the front side can be used as a heavy bass reproduction speaker.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS.
A first speaker 1 for low-pitched sound and a second speaker 2 for high-pitched sound are arranged on the front side of 0. An empty room 11 is defined at the upper part of the cabinet 1 by a partition plate 12, and the empty room 11 communicates with the outside by a duct 13. The third speaker 3 having the cavity 11 as a cavity is disposed on the upper plate 14 side of the cabinet 1, and the conical reflector 5 is disposed on the front side thereof. As the conical reflector 5, as shown in FIG. 1, a fourth speaker 4 having a lower housing 4 a formed in a conical shape is used. The fourth speaker 4 is arranged upward and further above it. Is provided with a diffuser 6 having a substantially elliptical shape. In this case, the diffuser 6 is supported by a plurality of columns 7 projecting obliquely from the upper surface plate 14, and the diffuser 6 is
Is suspended to support the fourth speaker 4 in a suspended state.

In the configuration example shown in FIG. 2, a conical diffuser 9 having an upper surface 9a as an arc-shaped surface is arranged as the conical reflector 5, and similarly to FIG. The diffuser 9 is supported, and the omnidirectional speaker section is a full-range speaker. In the figure, reference numeral 15 denotes a duct formed on the back side of the cabinet body.

[0009]

According to the speaker system of the present invention, a vacant space defined by a partition plate is provided at the upper part of the cabinet, and the vacant space communicates with the outside by a duct. A third speaker is disposed on the cabinet upper side and a conical reflector composed of the fourth speaker is provided on the front side of the third speaker, so that the third speaker becomes omnidirectional and the first to third speakers Since a different audio signal can be input to the first speaker and the second speaker on the front side of the cabinet for normal stereo reproduction, the third speaker is a surround speaker. When the third speaker is used for normal stereo reproduction, the first speaker on the front side can be used as a heavy bass reproduction speaker. Therefore,
The omnidirectionality and the directivity can be selectively used with one set of speaker systems, and the surround and the deep bass can be reproduced, so that the function can be remarkably enhanced.
In particular, since the fourth speaker was used as the conical reflector,
The omnidirectionality in the upward direction can also be secured, and the omnidirectionality can be further enhanced.
