SHOULDER-MOUNTED SPEAKER, SOUND IMAGE LOCALIZATION METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM

A shoulder-mounted speaker comprises an electronic controller including at least one processor. The electronic controller is configured to execute a plurality of modules including an attitude data detection module that is configured to detect an attitude of a body region on which the shoulder-mounted speaker is placed and is configured to acquire body region attitude data obtained by digitizing the attitude of the body region, an attitude data correction module that is configured to correct the acquired body region attitude data so as to be head attitude data, and a sound image localization processing module that is configured to use a head-related transfer function that corresponds to the head attitude data corrected by the attitude data correction module to subject an audio signal to sound image localization processing.
