DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 1, there is illustrated a sectional view of the first embodiment of the invention. As illustrated in this drawing, a speaker system with anion generator includes a speaker box 4 having a sound outputting hole 1 for outputting forwardly generated sound 2A from the speaker 2 and a port 3, provided at lower part of the sound outputting hole 1, for outputting a portion 2B' of the rearwardly directed sound 2B within the speaker box 4 to the forward direction. A discharge needle 5 for generating anions and a confronting electrode 6 for helping the discharging process are provided at a position nearby the port 3 of the speaker box. Also, a printed circuit board 7 to which the discharge needle is fixed and a high voltage generator 8 for applying high voltage to the discharge needle 5 through the circuit board 7 are provided.

The anions generating and spreading process according to the first embodiment of the invention will now be described.

When an audio system or a VTR is energized, the speaker 2 vibrates in response to the audio input to the speaker. As a result of the vibration of the speaker 2, forwardly generated sound 2A is provided through the sound outputting hole 1 and the sound 2B' is provided through the port 3 through the inside space of the speaker box 4.

When electric power is applied to the high voltage generator 8, the high voltage generator 8 applies the produced high voltage to the discharge needle 5 fixed to the circuit board 7. The discharge needle 5 discharges to the confronting electrode 6 and generates anions(5A) as a result of this process. The anion-generation process can be represented as follows:

e.sup.- +0.sub.2 .fwdarw.0.sub.2.sup.-

The confronting electrode 6 helps the discharging process of the discharge needle 5 to generate many anions(5A).

Referring to FIG. 2, the second embodiment of the invention comprises: a speaker box 4 in which there is a sound outputting hole 1 for outputting the forwardly generated sound 2A to the forward direction of the speaker 2, a discharge needle 5 located between the speaker 2 and the sound outputting hole for generating the anions; a circuit board 7 in which the discharge needle 5 is fixed thereon; and a high voltage generator 8 for applying the produced high voltage to the discharge needle 5 through the circuit board 7.

In the second embodiment, there is not provided a confronting electrode, but if a higher output is needed, a confronting electrode may optionally be provided.

The spreading process of the anions according to the second embodiment of the invention will now be described.

When an audio or VTR machine is energized, the speaker 2 vibrates in response to the audio input and, as a result of the vibration, the forwardly generated sound 2A is provided through the sound outputting hole 1 to the forward direction. When electric power is applied to the high voltage generator 8, the high voltage generator 8 applies the produced high voltage to the discharge needle 5 fixed at the circuit board 7. The anions generated by this process are spread by means of the sound pressure of the forwardly generated sound 2A of the speaker 2 through the sound outputting hole 1, whereby anions are spread into the indoor space in which this system is located.

This process will go on by means of the sound pressure of the forwardly generated sound 2A with the vibration of the speaker 2; thus, an indoor space in which this system may be located will be provided with anions. A confronting electrode (not shown) may optionally be provided to help the discharging process of the discharge needle 5 to generate anions (5A)).

Referring to FIG. 3, the third embodiment of the invention comprises a speaker box 4 including a sound outputting hole 1 outputting the forwardly generated sound 2A to the forward direction of the speaker 2, and a port 3, provided at lower portion of the sound outputting hole 1, for outputting a portion 2B' of the rearwardly generated sound 2B within the speaker box 4 to the forward direction. There is further provided an anions discharging port 9 located a predetermined position of the speaker box, a discharge needle 5 provided near to or inside the anions discharging hole 9 for generating anions, a circuit board which supports the discharge needle 5, and a high voltage generator 8 for applying high voltage to the discharge needle 5 through the circuit board 7.

The anions generating and spreading process according to the third embodiment of the present invention now will be described.

When an audio or VTR machine is energized, the speaker 2 vibrates in response to the audio input and, as a result of the vibration, the forwardly generated sound 2A is provided through the sound outputting hole 1 to the forward direction and a portion 2B' of the rearwardly generated sound 2B is provided to the port 3.

When electric power is applied to the high voltage generator 8, the high voltage generator 8 applies the produced high voltage to the discharge needle 5 fixed at the circuit board 7. The anions generated by this process are spread by means of the sound pressure of the sound 2B of the speaker 2 through the sound outputting hole 1, whereby the anions are spread into the indoor space in which this system is located.

FIGS. 4A and 4B illustrate a speaker 2 provided in the cabinet 10 of the television set, with the anions generating means positioned in the speaker box 4 according to the first embodiment of the present invention.

Thus, electric power is applied to the television set, sound is outputted from speaker 2, and anions are spread into the indoor space by means of the rewardly generated sound 2B.

In the drawings, reference numeral 11 denotes a CRT, and the discharge needle 5 may be provided at a predetermined position inside the cabinet 10, assuming the entire portion of the television cabinet 10 is the speaker box.

FIG. 5 is a view illustrating a fourth embodiment of the invention. This embodiment is identical to the first embodiment and will not be described except to note that there is additionally provided a anti-static coating 4C on the inside wall of the speaker box 10 for preventing static charge build-up from being formed on the inside wall of the speaker box 10 by the discharge.

Because the electrons (e-) generated according to the anions generation process reach the inner surface of the cabinet 4 faster than the ions O.sub.2, (the electrons (e-) move faster than ions O.sub.2) there is provided an antistatic agent coated on an inside surface of the cabinet.

In addition, to the embodiments illustrated it may be possible to coat the antistatic agent (10A) on the surface of the port 3. In this case, since the antistatic agent (10A) is also coated on the surface of the anions discharging port 3, static charge on the port 3 is eliminated, thus the anions generated as described above can be spread into the indoor space while freely passing through the port 3. U.V. materials may be provided on the inner surface of the cabinet 10 to prevent static charge build-up since the electrons (e-) of the U.V. materials are prevented from attaching to the inner surface of the cabinet 10. Also, static charge buildup can be prevented by combining an antistatic agent into the plastic materials to be moulded into the cabinet. In this case, static charge problems during anion formation can be prevented. Or, one could provide paper sheets or PVC sheets coated with U.V. materials thereon, in addition to antistatic agents. Finally, antistatic agents (4C) could be coated on the inner surface of the cabinet 4 and U.V. coating tape could be attached to the port 3. Alternatively, it is also possible to coat the antistatic agents (10A) on the port 3 and to provide U.V. coating tape on the inner surface of the cabinet 10.

FIG. 6 illustrates the fifth embodiment of the invention.

This embodiment is similar to the second embodiment shown in FIG. 2 except that anti-static agents (4C) are coated on the inner surface of the cabinet 4.

The anions generating and spreading process according to the fifth embodiment is same as that of the second embodiment described hereinbefore, so further description thereof will not be provided.

It is possible to form the cabinet 10 including the antistatic agents (4C) as illustrated in FIG. 5 wherein U.V. coating materials are used for the antistatic agents (4C), and U.V. coating tape is attached to the inner surface of the cabinet 10. In either case, the same effects as that described in the embodiment of FIG. 5 can be obtained.

FIG. 7 illustrates the sixth embodiment of the invention.

This embodiment is similar to the third embodiment shown in FIG. 3 except that antistatic agents (4C) and U.V. materials (10A) for preventing the formation of static charge are respectively provided on the inner wall of the sound outputting port 3 and on the inner wall of the anions discharging hole 5A.

The invention permits anions to be generated and dispersed while watching a television program. Since static charge is avoided, anions can be generated and effectively spread by means of the sound pressure of a speaker system.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
