ACOUSTIC DEVICE AND VIBRATION TRANSMISSION METHOD

Provided is an acoustic device with which it is possible to elicit a perception of sound coming out of a space larger than the actual space, without requiring burdensome cost and settings. A sound picked up by a microphone (2) is converted into an electrical signal, and a reflected sound component is extracted by a signal processing unit (5). The extracted reflected sound component is amplified byan amplifier (6), the extracted reflected sound component causes transducers attached to board surfaces on the back sides of acoustic structures (9) to vibrate, and the extracted reflected sound component is emitted as a reverberation sound from various surfaces such as the board surfaces (9b) on the front sides and the board surfaces on the back sides of the acoustic structures (9). A player (15) can thereby have the perception that the space has been naturally enlarged. 本发明提供一种音响装置，其即使不花费成本及设定的工作量，也能够形成如在比实际大的空间中发出声音这样的感觉。由传声器(2)拾音的声音被变换为电信号，在信号处理部(5)中提取反射音成分。提取出的反射音成分由放大器(6)放大，该放大的反射音成分使在各音响构造体(9)的背面侧的板面中安装的各换能器振动
