Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to an aroma generating device, and more particularly to an aroma generating device that uses a speaker equipped with an air blowing function to emit fragrance to the outside only when a sound is emitted.

Prior Art Traditionally, aromatic deodorizers installed in indoor bathrooms, entrances, living rooms, etc. evaporate or sublimate liquid or solid deodorizing ingredients to naturally diffuse fragrant particles indoors. It covers up and hides bad odors. However, this aromatic deodorant is in a state where the deodorizing ingredients are constantly being diffused, and consumption continues even when it is unnecessary, resulting in a lot of waste.Also, in order to extend the duration of the deodorant as much as possible, the amount of volatilization of the deodorant must be increased. However, there were disadvantages in that the necessary and sufficient aromatic and deodorizing effect could not be expected in some cases. On the other hand, in order to eliminate these drawbacks, deodorants are stored in air spray containers and the aromatic components are diffused only when necessary.However, these methods require cumbersome operations such as push buttons, and are difficult to use. The disadvantage is that the user only becomes aware of the need for deodorization after experiencing a bad odor, which is inconsistent with deodorization, that is, prevention of bad odor.

Furthermore, in the past, no sound equipment equipped with a mechanism for dispersing fragrance has been put to practical use, and in order to realize this idea, an electric fan or the like has been used as a blower to dissipate fragrance outside the device. However, the drawbacks of this method are that the device becomes complicated, the manufacturing cost increases, and noise is generated due to the rotation of the motor and fan.

Therefore, the inventor of the present application further discovered that if a hole is made in the diaphragm of a speaker, the air from the back of the diaphragm is sent out to the front through the hole during audio output, and the idea was to apply this speaker as a blower. I got it. This is an extremely innovative idea that had never been thought of before.

Purpose The present invention has been made in order to eliminate the drawbacks of the prior art described above and to put into practical use the idea of the inventor of the present application. By providing a plurality of holes and dispersing fragrance through the speaker, the fragrance is emitted at the same time as audio output, and efficient fragrance and deodorization can be performed when necessary. In addition, this increases the amount of fragrance released per use, releases fragrance when it is not needed at the same time, reduces fragrance consumption, and lengthens the period for replenishing and replacing fragrance. . Another objective is to make the device more compact and simple by using speakers with air blowing ability to dissipate fragrances, reduce power consumption and enable battery drive, and eliminate the need for blower fans and motors. The purpose is to prevent the noise that would otherwise occur.

Configuration In short, the present invention includes a container that contains a fragrance so that the fragrance always emanates, and a diaphragm that is provided with a plurality of concentric holes for blowing air, so that when the diaphragm vibrates, the diaphragm a speaker in which air from the back side of the container is sent out to the front side through the plurality of holes, an audio signal source input to the speaker, and a case accommodating at least the container and the speaker; The present invention is characterized in that the fragrance that volatilizes and fills the container is dissipated to the outside by the blowing action of the speaker when the speaker outputs sound.

Hereinafter, the present invention will be explained based on embodiments shown in the drawings. An onomatopoeic fragrance generating device 1, which is an example of a fragrance generating device shown in FIG. The device includes an onomatopoeia production device 4, which is an example of the above, and a case 5 that accommodates them. The case consists of a main body 5a and a back cover 5b, and FIG. 1 shows the case with the back cover 5b removed.

The perfume 2 is a very concentrated liquid stock solution, and is housed in a container 6, where it evaporates from the tip 6a of the container and fills the case 5.
The container 6 is removably fixed to the surface of a sponge 7 fixed to the case 5 with an adhesive applied to the surface 7a.

As shown in FIG. 4, the speaker 3 includes a cone 8 made of pulp, which is an example of a diaphragm, and the cone is provided with a plurality of holes 8a for blowing air. When the cone 8 vibrates, air from the back surface of the cone 8 is blown out to the front through the hole 8a, so that the speaker 3 has an air blowing function. And hole 8a is the fourth
As is clear from the figure, the cone caps 9 are arranged in a plurality of concentric circles around the cone cap 9, and even if the frequency of the audio signal input to the speaker 3 increases and the cone 8 causes split vibration, one of the cone caps The hole 8a is designed to vibrate. Therefore, the speaker 3 exhibits good air blowing characteristics over the entire range of audio output frequencies.

FIG. 5 shows a test device 10 for examining the air blowing performance of the speaker 3. The test device 10 includes a box 11 and a speaker 3, and the box 11 is provided with an opening 11a. In the illustrated state, smoke 13 from a lit cigarette 12 is emitted from the opening 11.
It enters the box 11 from point a, and is vigorously expelled as shown by arrow A due to the blowing action of the speaker 3. However, when the sound from the speaker 3 is stopped, the smoke 13 hardly leaks out from the hole 8a and the inside of the box 11 is filled.

Therefore, as shown in FIG. 2, when no sound is output from the speaker 3, the fragrance 2 evaporated from the container 6 fills the case 5 and does not leak to the outside.
Conversely, when sound is output from the speaker 3, it is dissipated vigorously as indicated by arrow B.

The onomatopoeic signal generator 4 is a microprocessor 1
Based on the data stored in 4, an onomatopoeic signal resembling running water from a flush toilet 15 is generated and input to the speaker 3. Further, the onomatopoeic signal generating device 4 is
An optical sensor 16 attached to the front of the case 5 of the onomatopoeic fragrance generating device 1 shown in FIG. 3 detects minute changes in illuminance to intermittent the generation of onomatopoeic signals.

FIG. 6 shows the onomatopoeic fragrance generator 1 installed in the toilet room 18. The optical sensor 16 detects the presence of the toilet 1 when the door 19 is opened or closed or when the user 20 moves his/her arm 21.
By detecting the change in illuminance within the room 8 and operating the onomatopoeic signal generating device 4, the sukkah 3 outputs the sound of running water to muffle the sound of excretion by the user 20, and at the same time diffuses the fragrance 2.

FIG. 7 shows an entrance chime fragrance generating device 22 which is another example of the fragrance generating device. The entrance chime fragrance generator 22 is an ornament consisting of a case 23 imitating a rock and a sculpture 24 in the shape of a bird, and the case 23 contains a fragrance (not shown),
It includes a speaker 25, a chime signal generator (not shown), and an optical sensor 26. The chime aroma generating device 22 is configured in exactly the same way as the onomatopoeic signal generating device 4, but the microprocessor 14
When the optical sensor 26 detects a change in illuminance, chime sounds consisting of various musical scales are generated.

Note that the button 28 in FIGS. 2, 3, and 6 is used to change the type of onomatopoeia, and the button 29 in FIG. 7 is used to change the type of chime sound.

Further, in FIGS. 1 and 2, reference numeral 30 denotes a battery serving as a power source for the onomatopoeic signal generating device 4. As shown in FIG.

Effects The present invention is configured as described above, and its effects will be explained below. The onomatopoeic fragrance generating device 1 shown in FIG. 6 completely stops generating onomatopoeia when the user 20 is outside the door 19. At this time, although the fragrance 2 evaporates from the container 6 and fills the case 5, it does not leak out of the case 5, so it is not wasted. Next, when the user 20 opens the door 19, the toilet 1
8. Since the illuminance changes rapidly, the optical sensor 16 detects this and an onomatopoeic sound of running water is generated from the speaker 3. At the same time, the fragrance 2 is vigorously dispersed by the blowing action of the speaker 3. The fragrance 2 has a fairly high concentration and is forcibly sent out by the speaker 3, so it rapidly diffuses into the toilet 18 and the fragrance and deodorization are gone by the time the user 20 sits on the toilet 15 and starts using it. Completed. Furthermore, if you want to continue the sound of running water while using the toilet bowl 15,
Since it is sufficient for the user 20 to cause a slight change in illuminance by slightly moving the arm 21, the fragrance can be generated until the end of use, and the bad odor generated during excretion can also be deodorized. After the user 20 leaves the toilet room 18, the generation of onomatopoeia stops, and therefore the generation of fragrance naturally stops as well.

In this way, the onomatopoeic fragrance generating device 1 efficiently diffuses the fragrance 2 with the sound of running water only when it is necessary to deodorize the toilet room 8, that is, when the toilet bowl 15 is used, and performs the aromatic deodorization. fragrance of time 2
The amount of fragrance emitted can be increased, and the amount of fragrance 2 can be saved by preventing the fragrance from emitting when not in use.
In addition, since there is no need to provide an electric fan to dissipate the fragrance 2, the size can be made small enough to be installed in the narrow room of the toilet room 18, and since the power consumption is low, the battery 30 can be used for a long time. It can be operated over a period of time.

Next, the entrance chime fragrance generating device 22 shown in FIG. 7 is installed at the entrance of a house or a store to notify visitors and at the same time deodorize the entrance or the vicinity of the entrance. That is, the optical sensor 26 detects the figure of the visitor, a chime signal generator (not shown) generates a beautiful melody chime sound from the speaker 25, and at the same time, the built-in fragrance is transmitted to the speaker 25. Dissipate by twisting.

Homes often have unique odors that residents do not notice because they have become accustomed to them, and this device 22 notifies residents of a visit and at the same time deodorizes the odor without the visitors noticing. It can be performed. In addition, in a store, it is possible to notify customers of their arrival and at the same time to increase their desire to purchase by using a beautiful melody and fragrance. Furthermore, since no electric fan or the like is provided, it is possible to prevent unpleasant noise from being mixed into the beautiful melody chime sound.

In the above embodiment, the audio signal source is limited to the onomatopoeic signal generator 4 and the chime signal generator, but is not limited to this, and may be any audio signal source such as a radio receiver or a record player. can be used. Further, the audio signal source and the speaker do not necessarily need to be housed in the same case as one unit, but may just be provided as a system.

Further, the fragrance may be in solid form rather than in liquid form.

Effects Since the present invention is configured and operates as described above, a plurality of ventilation holes are provided in the diaphragm of the speaker in the acoustic device, and the fragrance is dissipated by the speaker. The fragrance is diffused at the same time as the output, resulting in efficient aroma and deodorization when necessary. In addition, this increases the amount of fragrance emitted per use, and at the same time prevents the emission of fragrance when unnecessary, reducing the consumption of fragrance and prolonging the period for replenishing and replacing fragrance. is obtained. Furthermore, since a speaker with air blowing ability is used to diffuse the fragrance, the device can be made smaller and simpler, and power consumption is reduced, making it possible to run on batteries, which eliminates the energy generated by blowing fans and motors. This has the effect of preventing noise.
