レルに接続される。 Therefore, first, the voice coil drive magnet 1
To describe a specific example of vibrating the excitation body B, first, the structure of the excitation body B is a flat donut-shaped iron having double circular inner and outer walls 10 and 11 when viewed from above, and an open side on one side. An excitation coil 1 wound in a multilayered manner between the system housing 12 and the upright walls 10 and 11.
3, and this excitation body B is coupled to the speaker A. As a coupling means, a support 14 is installed in the center of the back of the pole yoke 3, and this support 14
A circular spring plate 15 is fixed to 4, and the excitation body B is suspended and connected to this spring plate 15 with a rivet 1 with its opening side facing the speaker side. Further, a common lead wire 17 from an unillustrated amplifier connected to the voice coil 7 is connected to the excitation coil 13 in parallel.

取出し得るものである。 Therefore, the operation of the excitation body B is such that due to the previous speaker operation, the audio current from the amplifier also flows to the excitation coil 13 of the excitation body B, and as a result, the housing 12 constituting the excitation body B as shown in FIG. inside and outside walls 1
0 and 11 become N and S magnetic poles, and a magnetic flux 18 that changes N and S alternately is generated between the two magnetic poles, and this magnetic flux 18
magnetically interferes with the leakage magnetic flux 19 coming from the magnet 1 of the speaker A, so that the excitation body B
The spring plate 1 vibrates around the spring plate 1 as a fulcrum, and this vibration naturally occurs in the low frequency band component with the high frequency component cut out by the coil 13.
5 and the mass of the excitation body B itself, the low frequency range is faithfully extracted, and this vibration is transmitted to the speaker A through the column 14, and can be extracted as deep bass.

せることも勿論可能である。 In the above embodiment, the excitation body B is vibrated by using the leakage magnetic flux of the voice coil driving magnet 1 that is originally included in the speaker A. However, as shown in FIGS. 5 and 6, a separate magnet 1a is used for exclusive use. May be used for. Further, as shown in FIG. 7, the speaker A and the excitation body B may be separated and assembled in a speaker box or the like. In this case, the sound pressure inside the box caused by the vibration of the excitation body B, the spring plate 15, It is possible to reproduce heavy bass through the synergistic effect of the resonant sound of the box. Furthermore, in the embodiment of the present invention, an example was shown in which the same signal as the audio signal to the speaker A is input to the exciter B, but depending on the application, independent audio signals may be input to the speaker and the vibrating member separately. Of course, it is also possible to do so.
