Abstract

PROBLEM TO BE SOLVED: To provide an acoustic device using vibration energy having extremely high sound pressure, generated in a housing of a box of a general acoustic speaker system, not in excitation of a vibration actuator, and performing music appreciation at an individual level and maturation of alcoholic beverage, especially wine, at the same time.SOLUTION: A container 9 for storing food product such as alcoholic beverage, is installed in a housing 2 of an acoustic speaker system, and the alcoholic beverage is excited by vibration energy by high sound pressure generated during music reproduction, for performing maturation of it.

Description

  In a general acoustic speaker system, a speaker unit is attached to a housing called a speaker box, and a sound wave generated outside the housing, that is, so-called air vibration is heard as sound. On the other hand, the air vibration generated inside the housing is rarely used acoustically. However, it is known that the sound pressure inside the housing is much higher than that outside the housing. This proposal relates to a food ripening device for wine, shochu or sake (hereinafter referred to as “alcohol”) using this very high sound pressure.

  Since around 1990, a variety of products such as music and underwater fluctuations are used for aging, and products for aging liquors and aging devices for applying vibration to containers of these products have been commercially available. (Refer to prior art documents)

  Conventional use of music for liquor brewing and aging is generally performed by attaching an actuator that vibrates in response to a music signal to the wall of a liquor brewing / aging container, and transmitting the vibration generated on the wall to the internal liquid. Until now, sound waves radiated into the air have never been used. The reason for this is that audio speakers that emit sound waves into the air are effective means of transmitting information for those that sense sound sensuously, but air has a low acoustic impedance, and liquids are transmitted via sound waves. In order to transmit vibration energy to a solid, loss due to impedance mismatch is large, and it is difficult to say that it is suitable as a means of transmitting vibration energy, and sound waves are highly diffusive and many diffuse to places other than the intended purpose. If the sound is not efficient and is given to alcoholic beverages, foods, etc. through air vibration through a loudspeaker, a loud sound that does not create an environment for listening to music is required.

  Actuator vibration methods are often performed by liquor producers in large facilities, and are not necessarily preferred by individual consumers, and are used only as a means of vibrating music, with the greatest purpose of viewing. There was a problem that was not the original usage.

  The proposal proposes a method to directly use the vibration energy of music, which has not been used so far, to mechanically brew alcoholic beverages, especially for aging, as well as mechanical vibrations by actuators. The idea was to devise an acoustic device.

  Compared to the outside of the speaker housing, the proposer of the present invention has found that it is possible to achieve both music appreciation and aging by using the low frequency region with a very high sound pressure inside the housing for aging. Achieving the task.

  The effect of scientific grounds such as ripening by applying vibration is detailed in Non-Patent Document 2, but it is said that alcohol that continues to give music vibration is promoted by the speed at which alcohol and water become familiar, and the mouth feels softer. The effect was confirmed.

  The biggest effect of this proposal is that music and liquor enthusiasts can rip their own liquor with their favorite music and decide the maturity level by themselves. Found different consumer benefits.

  A container that can store alcoholic beverages is installed inside the housing of a commonly used acoustic speaker, and the container is filled with alcoholic beverages and plays music, allowing music to be listened to outside the housing and alcoholic beverages to mature inside the housing. Structure.

  In order to confirm the effect of this proposal, Example 2 in which the reproduction frequency-sound pressure inside and outside the speaker system housing was measured in Example 1, the sound pressure difference was compared, and an aging container was attached in the speaker housing. The speaker system of Example 3 was prototyped, wine aging was attempted by playing music, and a taste test was performed using a monitor.

A speaker system that measures the difference in sound pressure inside and outside the speaker housing is prototyped with the following specifications, and an input signal 1w is added based on the JIS standard. The outside of the housing is 1 m in front of the speaker, and inside the housing at the position shown in FIG. The reproduction frequency-sound pressure was measured.
Case dimensions: width 232mm, height 154, depth 152mm (internal volume about 5l)
Speaker unit: 10cm full range unit

  As is apparent from FIG. 2 showing the measurement results, the sound pressure inside the housing is much higher than the outside of the housing at a frequency of 800 Hz or less, especially about 20 dB around 170 Hz (f0) and about 30 dB around 100 Hz. It was confirmed that the use of this high sound pressure enabled effective aging of alcoholic beverages.

  A container for storing liquor etc. is installed inside the speaker used in Example 1 (FIG. 3), wine that is susceptible to external factors is poured into the container, and the music playback time is from 10 minutes to 60 minutes, and every 10 minutes. The aging effect was confirmed by 10 monitors using a taste test based on the scent and the mellowness that was felt when it was put in the mouth.

Music was performed using a relatively young product of Bordeaux wine where aging is important. These are shown as example conditions below.

The results are shown below. A change in fragrance and mellowness was felt from 10 minutes of music playback time, and in 40 minutes of playback time, all members felt fragrant and mellow, leading to the expression of wine lovers “opening wine”.

  At 50 minutes, 2 monitors, and at 60 minutes, one more monitor evaluates as “too open”, and the “wine open” state may affect the playback time and time to receive sound pressure. confirmed.

  The difference in the playback time that feels change is considered to be a difference in the sense of each individual monitor and the preferred “open” state. That is, an individual's favorite maturity can be selected according to the reproduction time.

  In Example 2, a conventional box-type speaker system was examined. Here, a speaker having a sound tube (FIG. 4) was prototyped, and a glass container for placing alcohol in a so-called sound guide in which sound is transmitted. (Open top surface) was installed, and the aging effect by sound was confirmed in the same manner as in Example 2.

The results are shown below. The taste test evaluation by the monitor under the same conditions as in Example 2 showed a ripening effect as in Example 2, but the result required a little longer music playback time than in Example 2. The reason for this is considered to be that the transmission efficiency was reduced only from the upper surface where vibration transmission was released because the storage container was made of glass.

  Although it has been explained that liquors can be matured by using a very high sound pressure in the speaker housing in the specific shape of Examples 1 and 2, the present proposal is not limited to these shapes, Also, the music and wine used are not limited.

  Alcohol can be matured by consumers, allowing both music appreciation and aging to be achieved, and the aging degree can be selected according to individual preferences. There is a high possibility that it can be used to create a new taste culture that fuses music and food from the point where it can be matured while listening to music.
