    • It is aimed to provide a bone-conduction speaker device which makes no leakage of sound annoying the other and does not restrict posture and rolling-over motion of the user when lying on a bed or sitting on a sofa, and which makes highly reliable and excellent transmission and receiving of sound signal as to enable enjoying of music or the like with almost no locational restrictions. The speaker device comprises: a transmitter converting the inputted sound signal into output of infrared signal and then transmitting it; a receiver demodulating the inputted infrared signal into the sound signal; a bone-conduction speaker amplifying the sound signal and outputting it as sound vibration; and a pad-shaped elastic cushioning body holding on its surface the bone-conduction speaker, thereby forming a pad embedded with the bone-conduction speaker(s). Photo-acceptors for the receiver are arranged on fringe of the cushioning body as spaced apart to each other.
    • 旨在提供一种骨传导扬声器装置,其不会使声音泄漏恼人,并且不会限制使用者躺在床上或坐在沙发上时的姿势和滚动运动,并且这使得高可靠性和 良好的声音信号的传输和接收,使得能够享受几乎没有位置限制的音乐等。 扬声器装置包括:发射机将输入的声音信号转换为红外信号的输出,然后发送; 将输入的红外线信号解调为声音信号的接收机; 放大声音信号并将其作为声音振动输出的骨传导扬声器; 以及在其表面上保持骨传导扬声器的垫状弹性缓冲体,从而形成嵌入骨传导扬声器的垫。 用于接收器的光接收器被布置在彼此间隔开的缓冲体的边缘上。
