Definitions

  • the present invention relates to a speaker apparatus for use in sound equipment.
  • the present invention aims to provide a speaker apparatus wherein a light source is arranged in front of a speaker body to illuminate the front surface of the speaker body and to allow the reflected light to be radiated forward.
  • the speaker apparatus emits light and, therefore, the design effect of the speaker apparatus is much improved.
  • the intensity of illumination can be varied in response to the intensity of the sound through the control of the light source by the sound signal supplied to the speaker body, the sound is enabled to be visually enjoyed.
  • Fig. 1 is a construction drawing showing a speaker apparatus of an embodiment of the present invention
  • Fig. 2 is an electric system diagram showing an applied example of the speaker apparatus in Fig. 1
  • Figs. 3 and 4 are an external view and an electric system diagram, respectively, showing another embodiment of the present invention.
  • Fig. 1 is a construction view showing an embodiment of the present invention.
  • (1) denotes a speaker body
  • (2) denotes a sound box for securely supporting the speaker body (1)
  • (3) denotes a protecting member, made of a protecting net or the like which transmits sound and light therethrough, being mounted on the sound box (2) for covering the front of the speaker body (1).
  • (4) denotes a decorative plate adhered to the center of the protecting member (3)
  • (5) denotes a light source of a lamp or the like disposed at the back of the decorative plate (4) and opposing the central portion of the diagram (la) of the speaker body (1), the light source being connected by lead wires (6) to a terminal block (2a) at the back of the sound box (2) so as to be supplied with driving power, together with the input signal for the speaker body (1), from an external apparatus.
  • the light source (5) is lighted and illuminates the front surface of the diaphragm (1a), and its reflected light is radiated through the protecting member (3).
  • the decorative plate (4) serves for shielding the light of the light source (5) from being directly radiated frontward.
  • the speaker apparatus looks emitting a circle of light corresponding to the front shape of the diaphragm (la).
  • FIG. 2 An example of electric circuit for use in the above described speaker apparatus is shown in Fig. 2.
  • (7) denotes a power amplifier for supplying a sound signal to the speaker body (1)
  • (8) denotes a controller for detecting the output signal from the power amplifier (7) and, in response to the signal, for generating an output which is adapted to drive the light source (5).
  • the intensity of the light from the light source (5) varies in response to the intensity of the sound produced by the speaker body (1) and the sound is enabled to be also enjoyed visually.
  • the apparatus can serve as an indicator apparatus of sound volume level.
  • the design effects can further be improved by coloring the light of the light source (5) or by employing a plurality of the light sources (5).
  • Figs. 3 and 4 show another embodiment of the present invention, where like parts to those in Figs. 1 and 2 are denoted by like reference characters.
  • a woofer (11), a squwarker (12), a tweeter (13), and a supertweeter (14) are housed in a sound box (2) to form a four-way type speaker apparatus.
  • Each of these speakers (11), (12), (13), (14) is arranged in the same way as that in Fig. 1 wherein the light source (5) is disposed in front of and opposing the diaphragm (la) of the speaker body (1).
  • the light source (5) is disposed in front of and opposing the diaphragm (la) of the speaker body (1).
  • the sound output signal produced by a power amplifier (7) is supplied through filters (9a), (9b), (9c), (9d) having different pass bands to the speakers (11), (12), (13), (14), respectively, each of which is adapted to reproduce sound in response to the respective signal of reproducible band.
  • the output signals from the filters (9a), (9b), (9c), (9d) are supplied to controllers (8a), (8b), (8c), (8d), which are adapted to supply electric currents to the light sources (5a), (5b), (5c), (5d) in response to intensities of the signals inputted, thereby to cause these light sources to vary their light intensities.
  • the intensities of the lights of the light sources (5a), (5b), (5c), (5d) vary in response to the operating conditions of the speakers (11), (12), (13), (14), and the reflected lights radiated to the front of the speaker apparatus may be utilized as a simple spectrum analyzer. It is possible to improve the reflection efficiency of the light by providing a specular gloss for the surface of the diaphragm (la) of the speaker body (1), and to enhance the design effects by providing different colors for the light sources (5a), (5b), (5c), (5d).
  • the present invention was described in conjunction with a four-way type speaker apparatus, the present invention can be equally applied to any multi-way, two-way or more, speaker apparatus.
  • the present invention may produce a considerable effect when the same is applied to the speaker apparatus installed inside automobiles. That is, although the interior of an automobile when driven in the nighttime becomes dull and monotonous, the speaker apparatus according to the present invention can break the monotony inside the car by providing reproduced sound and by varying the light in response to the reproduced sound.
