Abstract
The utility model discloses an electroacoustic unit occupying less space and belongs to a stereo device. The electroacoustic unit occupying less space comprises a loudspeaker magnetic steel combination body, a voice coil and centering supporting pieces. A low-pitch central portion is designed to be in a moving magnetic steel state which is opposite to a normal moving coil loudspeaker. A lower edge of the voice coil can be directly and fixedly connected with a sucker which can be arbitrarily and fixedly sucked on a smooth surface of a door, a window, glass or furniture. The middle portion of the voice coil is fixedly connected with the loudspeaker magnetic steel combination body through two enhanced center-locating supporting pieces which are arranged at intervals along the axial direction so that a coiled upper portion of the voice coil can be maintained to be between gaps of a magnetic field of the magnetic steel. When changing electricity currents pass through the relatively fixed voice coil, the loudspeaker magnetic steel combination body can be driven by an electromagnetic effect of the voice coil to beat along the axial direction of the voice coil, just like the voice coil is directly fixed on the surface of the door, the window, the glass and the furniture, and is enabled to become a part and extension of sound created by the electroacoustic unit, and therefore a purpose of occupying less space is achieved.
