Embodiment Construction

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0023] figure 1 It is a perspective view showing the appearance of a speaker device according to an embodiment of the present invention.

[0024] In addition, the speaker device 1 related to the present embodiment is, for example, a device in which a microphone and a speaker are used in a teleconference such as a video conference. A device in which the sound is amplified by a loudspeaker.

[0025] Such as figure 1 As shown, the speaker device 1 according to this embodiment has a cover member 2 , a holding member 3 , a speaker 15 , and a speaker box 20 .

[0026] The holding member 3 and the speaker box 20 are formed of resin such as ABS (acrylonitrile-butadiene-styrene), for example.

[0027] The cover member 2 is provided on the holding member 3 to cover the upper surface of the holding member 3 . The cover member 2 is formed of a sound-permeable material such as ...

Abstract

A speaker system enabling efficient dispersion of intelligible sound far in all directions from a specific point along a certain planar direction, provided with a single speaker (15), a first reflective surface (3f) arranged facing a sound output direction (A1) of the speaker (15) and reflecting the sound to directions different from the output direction, and a second reflective (21f) surface arranged facing the first reflective surface (3f), wherein the distance between the first reflective surface (3f) and the second reflective surface (21f) increases continuously in proportion to the distance from the center of the speaker and wherein the first reflective surface (3f) and the second reflective surface (21f) diffuse sound radially from the speaker (15) to directions different to the sound output direction (A1) of the speaker (15).

Description

technical field [0001] The present invention relates to loudspeaker devices. Background technique [0002] For example, to radiate sound from a certain point to the entire surrounding in a substantially horizontal direction, it is necessary to arrange a plurality of speakers in different directions. [0003] However, when a plurality of speakers are arranged in different directions, the sounds output from the speakers interfere with each other, and there are positions where the sound sounds strong and where the sound sounds weak. Therefore, if a plurality of speakers are used, it is difficult to effectively disperse sound. [0004] On the other hand, Patent Document 1 discloses a technique for receiving the voices of participants in a conference with a microphone and spreading the voices over a wide range using a single speaker and reflector. [0005] [Patent Document 1] [0006] Japanese Patent Application Publication No. 2003-87887 [0007] However, in the technique of...
