Function The present invention is constructed as described above, and its function will be explained below. In FIGS. 1 to 3, when the television receiver 1 is placed in a receiving state, images and sounds are obtained by reproducing broadcast waves. This Eirin signal being played is an image! ! ! The lIk extraction unit 8 processes the U into an easily recognizable form, and the image gI! In the recognition unit 10, the image is compared with figures and color distribution patterns stored in the image memory unit 9 in advance. As a result of the comparison, if the patterns match and the content of the image is recognized, it is output to the B@information integration unit 14. on the other hand,
Similarly, the voice signal being played is subjected to q# fine extraction processing in the voice percentage fine extraction section 11, and is compared with words and phrases previously stored in the voice memory section 12 in the voice recognition section 13, and -!
Then, it is output to the recognition information integration section 14. li! ! The identification information integrating unit 14 integrates the output of the image recognition and the output of the voice recognition, and finally determines which perfume 2 is to be emitted to synthesize a fragrance. For example, a ``spherical and discolored object'' is recognized by a video signal, and ``orange'' is recognized by an audio signal.
when the word iiiwlk is determined to produce a citrus fruit odor. Based on the determination, the selection signal generating unit 6 generates a selection signal for driving the solenoid valve 18 connected to the container 3 containing the citrus fragrance 2. The fragrance 2 evaporates out of the container 3 via the solenoid valve 18 opened by the selection signal.

In the speaker 6, the diaphragm 24 vibrates for audio reproduction, and air is blown from the back side of the diaphragm to the front side through a large 24g, and the volatilized fragrance 2 passes through the pipe 20 to the speaker cover 23. It is collected and emitted by the speaker 6 to the outside of the TV set, and then diffused into the reception area, so that the viewer can smell the smell of "orange".

Since the holes 24a of the speaker 6 are arranged in a plurality of concentric circles, they cover all of the frequency characteristics of the diaphragm 24 from the piston motion range to the divided vibration range, and uniform air blowing characteristics can be obtained.

Furthermore, the fragrance generated by the device of the present invention does not necessarily have to correspond to an actual odor, and the image pattern to be stored in the image memory section 9 can be freely set. In the case of color distribution, it may be assumed that it is a blue sky and emit peppermint fragrance 2, or if the screen 17 has a large amount of green color distribution, it may be assumed that it is a plant and emit fragrance 2 of tree-based perfume. can. Furthermore, in the case of voice, it is possible not only to recognize words, but also to determine the gender based on the difference in the frequency components of the voice, and in the case of a female voice, it is also possible to emit fragrance 2 of a women's perfume.

Next, a radio cassette tape recorder 30 shown in FIG.
A case will be explained in which a radio broadcast is received and audio recorded on a cassette tape is played back. First, the fragrance selection device 32 processes the audio output and recognizes the content of the reproduction information.

One or more of the electromagnetic valves 43 built into the valve unit 33 are opened by the selection signal generated there. The fragrance 35 volatilized from the opened electromagnetic valve 43 is emitted to the outside of the radio cassette tape recorder 30 by the speaker 34.

Since the speaker 34 has dual functions of sound reproduction and air blowing, there is no need to install a blower device such as an electric fan, which prevents noise generation and deterioration of sound quality.
The weight reduction and simplification required for general radio cassette tape recorders can be achieved.

In the above embodiments, only the television receiver 1 and the radio cassette tape recorder 3o are illustrated as the sound reproduction device with a fragrance generating mechanism, but it is also possible to use a device such as a wired still image broadcasting device, a video disk device, etc. that is picked up at a remote location.

Furthermore, in the above examples, the perfumes are liquid perfumes 2 and 3.
5, solid fragrance may also be used. Further, although the solenoid valve 18 is used as the valve, any mechanism may be used as long as it can be controlled by an electric signal.

In addition, although the description has been made assuming that the speakers have 6 and 34 speakers and have a plurality of concentrically arranged holes 24a and 48a on the diaphragms 24 and 48, the diaphragm The speaker also has holes arranged in a spiral pattern from the center toward the cone edge.
It has good air blowing characteristics over the entire range of sound reproduction frequencies, and may be used.

Effects Since the present invention is configured and operates as described above, a plurality of fragrances are housed in respective plurality of containers, and video signals and audio obtained from reception of broadcast radio waves or pickup of recording media are transmitted. A fragrance selection device that recognizes the information content through signal processing and generates a selection signal corresponding to the content is provided, and a valve unit that opens the container of each fragrance according to the selection signal is provided, and the fragrance that volatilized outside the container is provided. Since the device of the present invention is equipped with a blower device to dissipate the air to the outside, that is, toward the viewer, when receiving a broadcast or playing a recording, the device of the present invention can recognize the image and sound and emit a scent that corresponds to the content. The effect is that the scent is diffused into the car where it is installed, giving the viewer the impression that the odor has been transmitted from a remote location. In addition, the ventilation device for dispersing the fragrance has multiple holes in the diaphragm and uses a speaker that also serves as sound reproduction, eliminating the need for an electric fan, etc., which eliminates the noise caused by fan rotation. It is possible to simplify and downsize the device, thereby achieving the effect of reducing manufacturing costs. In addition, the holes in the diaphragm of the ventilation speaker are arranged in a multi-stage concentric circle or spiral pattern, which covers the frequency characteristics of the speaker from the piston motion range to the split vibration range, resulting in good sound reproduction over the entire range of sound reproduction frequencies. There is a good effect that can be obtained by having good air blowing characteristics.
