Abstract

A thin speaker device capable of radiating a large volume of reproduced sound by using a relatively simple structure, wherein an audio signal is inputted in a voice coil without adversely affecting vibration of the voice coil. A speaker device is provided with a vibration direction changing section for transmitting vibration of a voice coil to a vibration plate after changing the direction of the vibration, and also with a holding section for holding on a stationary section the voice coil so that the voice coil linearly vibrates. An audio signal inputted in an audio signal input terminal provided to the stationary section is inputted into the voice coil through the holding section.

Description

technical field [0001] The present invention relates to a loudspeaker device. Background technique [0002] As a general speaker device, a power type speaker device is known (for example, refer to Patent Document 1). The dynamic loudspeaker device is, for example, figure 1 As shown, a frame 3J, a conical diaphragm 21J, a voice coil bobbin 610J supporting the diaphragm 21J on the edge 4J of the frame 3J, joined to the inner peripheral portion of the diaphragm 21J, and a voice coil bobbin 610J supporting the frame 3J are provided. The damper 7J, the voice coil 611J wound around the voice coil bobbin 610J, the yoke 51J, the magnet 52J, and the thin plate 53J have a magnetic circuit that forms a magnetic gap in which the voice coil 611J is arranged. In this speaker device, when an audio signal is input to the voice coil 611J, the voice coil bobbin 610J vibrates by the Lorentz force of the voice coil 611J generated in the magnetic gap, and the diaphragm 21J is driven by the vib...
