Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mechanism for improving the sound sensation of a speaker. The gist of this invention is a rainbow lighting device characterized in that a light emitting section is provided on an end surface of the diaphragm for displaying the sound of the diaphragm as light.

The following drawings show embodiments of the present invention, and FIG. 1 shows an example of a speaker used in the present invention, in which a diaphragm 2 and a partition wall 3 are provided in the center of the speaker, and voice coils 4 and 4 are provided at both ends of the bobbin. 4' and integrally form a vibration system as a vibration element 5, a voice coil 4, 4', and inject the magnetic fluid 9 so as to fill the space between the voice coil portion and the magnetic pole.

Air is sent from the compressor 13 through the pipe 12 to the air hole ILII' that penetrates through the center of the center pole and branches into the empty chamber 10.10' in the bobbin. There is no dubbing, and the vibration element is supported by dubbing in a 10° 10' space in the bobbin. Since the cavity within the bobbin is sealed with magnetic fluid, the compressor may be smaller than in a case where no magnetic fluid is used.

The magnetic fluid is a mixture of fine magnetic powder such as magnetite or ferrite and a diester solvent, dioctyl azelate. It stores the heat of the voice coil, suppresses temperature rise, suppresses resonance without disturbing vibration, and has no self-centering effect.

The vibrating element l-5 is supported on the speaker box 14 by a bridge 15.15'. This bridge is provided in an arch shape facing the upper plate of the speaker hook 14, a yoke 8.8' is fixed inside the bridge, and the diaphragm 2 is loosely fitted into the opening 16 of the speaker hook 14. The speaker is not fixed to the speaker box with a damper, etc.

FIGS. 2 to 4 show a diaphragm 2 of a floating speaker such as the one in the above example above mounted on the top surface of a box 14, and a plastic quarter-piece placed over the diaphragm to emit sound waves from above.・It is reflected on the inner surface of the spherical reflecting plate 17, and the listener 18
It radiates to the front 19 where there is a person. Sound direction 1
9 and human ears 20, 21 to reach the human body, it also flows approximately parallel to the plane 23 containing the speakers and ears 20, 21 to reach the human body, and thus the sound The sound is radiated three-dimensionally to surround the human body, and the sound from the speaker is mellowed by the reflective plate, increasing the sense of reality.

In addition to the above-mentioned reflecting plate 17, a rod-shaped one 24 as shown in FIG. 3 or a flat plate-faced one 25 as shown in FIG. 4 can also be used.

5 to 7 show the periphery of the diaphragm 2 of the speaker of the above example, and the diaphragm 2 is inserted into the circular opening 16 of the box 14 through the gap 26 as shown in FIG. If the diaphragm 2 moves beyond the edge of the aperture 16 due to vibration, the air resistance between it and the edge of the aperture during vibration changes and changes, distorting the sound output characteristics of the speaker. As shown in the figure,
Close to the outer edge of the diaphragm 2, a fence 28 is provided around the diaphragm at the edge of the opening 16 of the box 14 in the vibration direction 27 of the diaphragm and at least the maximum vibration travel distance of the diaphragm. .

This prevents the diaphragm 2 from shifting from the edge of the opening 16 as shown in FIG. By providing a duct 29 on the side plate of the box 14 as shown in the figure, the phase of the sound behind the diaphragm is reversed, making it possible to enhance the bass.

That is, the diaphragm 2 vibrates evenly due to the fence 28, and its frequency characteristics are significantly improved.

8 and 9 show a speaker system in which a box 14 is provided with both a horizontal diaphragm 2 as shown in FIG. 1 and a vertical diaphragm 3o.・Rugara 7,000-・The sound of Ruggara is emitted upward, and the diaphragm 30 is made to emit a sound of 6,000 to 40,000 Hz forward, so that the sound surrounds the human body 18 three-dimensionally. It is something that radiates.

As a result, a single unit can function as both a stereo and a super woofer, producing a compact yet low-cost speaker system that produces sound quality comparable to that of a large-sized device, a wide band of sound, and requires less input.

10 and 11 show holes 32 in the box 14 in the same direction as the vibration direction 31 of the upward diaphragm 2 as shown in FIG.
This is a system in which a horn-shaped sound path 33 is provided in the space that is raised and diffused in a direction perpendicular to the direction of the hole.
o may be provided.

As a result, even if the box 14 is small and thin, the same sound quality as a large speaker box can be obtained. In particular, the sound path 33 in the diffused space greatly expands both the bass and treble ranges, extending the bass range to 5 Hz, dramatically improving frequency characteristics.

FIG. 12 shows the sound of the diaphragm 2 being illuminated onto the front end face 34 of a quarter-sphere reflector 17 that covers the vibrating element with the diaphragm 2 facing upward in the above example and projects the sound forward. For example, an LED, L
A light emitter 37 such as a GD is electrically connected to an input circuit to a speaker to emit light with different luminous intensity and color depending on the volume and sound quality, and the light is applied to the end surface 34 by the edge effect of a transparent reflector. It is something that can be done. Alternatively, one or more light-emitting portions 35 of the light-emitting body may be provided on the front end surface 34 as shown in FIG.

As a result, the light emitted from the front end of the reflector can be displayed as a high-performance lamp, and by changing the intensity, position, and color of the light depending on the sound quality and the volume, the sense of rhythm can be improved with the visual sense of music, etc. It can be used as an enjoyable speaker, and its effect is remarkable in a dark room.

In particular, when sound is displayed using colored lights, the arc-shaped part at the front end of the spherical shell shines like a rainbow, improving the sense of sound through a completely new audio-visual experience.

As the electrical and mechanical means for controlling each of the above-described embodiments, known means can be used.

Further, each of the above-mentioned embodiments has a close relationship with each other, and each of the above-mentioned embodiments has a close relationship with each other, and combinations of these and various aspects thereof are all included in the present invention. .
