Embodiment Construction

[0040] Hereinafter, a sound reproduction system according to an embodiment of the present invention is described with reference to the drawings. In this embodiment mode, the case of reproducing the multi-channel surround sound of the above-mentioned 5.1-channel method will be described as an example.

[0041] The embodiments described below are examples in the case where video viewing and 5.1-channel surround sound listening are performed by using video signals and audio signals reproduced in a DVD player. In this embodiment, when the TV receiver screen is used for image viewing, 5.1-channel multi-surround sound is reproduced by using two speakers included in the TV receiver and two speakers provided near the listener's ears.

[0042] FIG. 1 shows an overview of a sound reproduction system according to this embodiment.

[0043] As shown in FIG. 1, the sound reproduction system according to this embodiment includes a television receiver 1 including two speakers 11FL and 11FR f...

Abstract

A voice reproduction system is provided in the present invention, it comprises: a first loudspeaker, for supplying a first track audio frequency signal to the first loudspeaker, and placing the first loudspeaker, leading reproducing video / audio generated by a first track audio frequency signal to positioning the auditor front directional position; a pair of second loudspeakers, for supplying audio frequency signal executed virtual sound source process to the second loudspeakers; a virtual sound source process unit, for executing virtual sound source process to audio frequency signals of multiple tracks; volume detecting unit, for detecting volume of the first track and other tracks; a volume comparing unit, for comparing volume of the first track with volume of other tracks; and a control unit, for controlling plus of audio frequency signal of the first track and other tracks.

Description

technical field [0001] The present invention relates to a sound reproduction system that reproduces sound by performing a virtual sound source process on audio signals of partial channels of a plurality of channels. The invention also relates to a sound reproduction method in a sound reproduction system. Background technique [0002] Video and sound reproduction systems known as "home theater systems" have become increasingly common. In video and sound reproduction systems, by displaying video on a display with a relatively large screen so as to reproduce it from a DVD (Digital Versatile Disc) or the like, sound is reproduced in a multi-channel surround sound method, and recently Sound is reproduced in the 5.1-channel method. Therefore, video and sound can be reproduced powerfully. [0003] In the sound reproduction system of the 5.1-channel method, four types of speakers are used: one located in front of the listener (hereinafter referred to as "front"); one located in t...
