发明名称 Information processing device and speaker unit applicable thereto
摘要 An information processing device and a speaker unit applicable to the device. In one aspect of the present invention, the device includes a housing, a pole piece, a voice coil, a magnet, and a frame. The housing has an elastically vibratory vibration region. The pole piece has a first end and a second end. The first end is fixed to the vibration region of the housing. The voice coil is fixed to the second end of the pole piece. The magnet forms a magnetic field interlinking the voice coil. The frame fixes the magnet to the housing at a region other than the vibration region, for example. With this configuration, vibration of the voice coil due to a current flowing through the voice coil is transmitted through the pole piece to the vibration region of the housing, thus eliminating the need for a vibration board of a speaker and further eliminating the need for formation of holes for sound transmission through the housing.
