Problems solved by technology

The reason is that when the user arranges the speaker system of Patent Document 2 as a speaker system for a TV set on the left and right sides of the TV set and outputs sound from the speaker system, the speaker system is arranged so as to surround the above-mentioned pair of speakers. The reflection plate also suppresses the sound quality degradation caused by the sound going around the back side of the TV

Abstract

The objective of the present invention is to obtain a speaker system which is capable of forming an optimal sound field over a wide area, with which a reduction in size (slimming) can be readily achieved, and with which a deterioration in sound quality is not liable to occur even if the speaker system is employed in a television. This speaker system (100) is provided with two speakers (120) havingsound output surfaces that face one another. The speaker system (100) is also provided between the two speakers (120) with a diffuser (110). Sound emitted by the two speakers (120) is reflected by the diffuser (110) in a specific half-space direction.

Description

technical field [0001] The present invention relates to a speaker system and a display device equipped with the speaker system. Background technique [0002] Conventionally, a speaker system is configured by arranging two direct-radiating speakers in parallel (also simply referred to as a left-right arrangement) so that the sound output surfaces (that is, diaphragms constituting the speakers) face the same direction. Although such a conventional speaker system can form an optimum sound field at a position equidistant from the left and right speakers, it cannot form an optimum sound field at a position deviated from a position equidistant from both speakers. [0003] Therefore, recently, a speaker device (opposite arrangement type speaker device) has been proposed that includes a pair of speaker units whose sound output surfaces face each other and a reflection member that reflects the sound emitted by each speaker unit in the direction of the listener. [0004] For example,...
