Description

Technical Field

[0001] The present invention relates to a sounding device that can be used in a wide range of fields such as the field of meditation and the field of relaxation.

Background Art

[0002] Meditation is said to calm the mind and achieve a state of emptiness, and is effective in reducing stress. Also, relaxation refers to a state in which both the mind and body are released from tension. As a method of inducing such a state, a sinking bowl has been known heretofore. However, with a sinking bowl, it is necessary to constantly rub or tap the edge of the bowl using a so-called stick. Also, a rin is known as one of the Buddhist tools, and it is a device that strikes the rin using a rin stick.

[0003] The inventor of the present invention has studied a sounding device that can produce a sound without using the above-mentioned stick or rin stick, induce meditation, and also be used as a rin, and thus arrived at the present invention.

[0004] The applicant of the present application has previously proposed a vibrating bell, which mainly vibrates the edge of the opening so that the amplitude of the vibration of the rin part becomes large (Patent Document 1). Also, the applicant of the present application has previously proposed a floating rin device, which strikes the rin using a rin stick (Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0006] The present invention aims to provide a compact, automatically controllable sound-producing device. [Means for solving the problem]

[0007] The sound-producing device according to the present invention comprises a sound-producing unit and an excitation unit, characterized in that the sound-producing unit produces sound by resonating with a vibration signal output from the excitation unit. Here, the sound-producing section is preferably a recessed shape having an opening, and the vibration-generating section is preferably located in the center of the recessed shape, and the vibration-generating section may be controlled by an external signal.

[0008] If the sound-producing part has a concave shape with an opening, when the sound-producing part vibrates and produces sound, the center of the concave shape becomes a node of vibration. For example, if the sound-producing part is roughly bowl-shaped or roughly hemispherical in shape with a hollow recess on the inside, the center of the bottom of the recess becomes a node of vibration, and sound is produced as the side walls extending from the bottom towards the opening vibrate. Since each sound-producing part has its own natural vibration, when vibrations with a frequency matching the natural vibration are applied from the excitation part, the sound-producing part resonates with the excitation part, and sound is produced.

[0009] In the present invention, the vibration section may have a vibrator and be integrally provided at the bottom of the sound-producing section. Alternatively, a separate table-shaped vibration platform may be provided, and a vibration platform may be formed on this platform. The sound-producing unit may then be placed on the vibration platform to provide vibration to the sound-producing unit. The vibrator installed in the excitation section can be a piezoelectric element or a coil element, and various known vibrators can be used. Furthermore, by mounting the oscillator on an IC chip, excitation can be controlled by an external control signal.

[0010] By integrally providing the vibration unit with the sound-producing unit, it is also possible to generate sound using an external signal while the sound-producing unit is levitating in the air, using the levitating bell device disclosed in Patent No. 6931925, which was previously proposed by the present applicant.

[0011] Furthermore, by providing a knob function in the inner center of the recess of the sound-producing part according to the present invention, it is possible to pinch and move this knob with your fingertips while the sound-producing part is being played. [Effects of the Invention]

[0012] In this invention, by placing the excitation section at the nodes of the vibration of the sound-producing section so that the sound-producing section vibrates in its natural frequency, even a small-output oscillator can gradually produce a louder sound. Furthermore, in addition to the fundamental frequency, the natural frequencies may also include second and third harmonics that do not interfere with the natural frequency. The sound produced according to the present invention gradually begins to sound due to the natural frequency of the sound-producing part, thus achieving a mystical sound state, and it is also possible to produce sound for a long period of time. It's possible to create sounds that seem to emerge from the silence, which is very appealing. Of course, it can also be expected to relatively reduce unpleasant vibrations, making it ideal for enjoying pleasant sounds for extended periods. Such sound-producing devices can be used to guide meditation in the field of meditation or to maintain a state of relaxation. Furthermore, since it can be controlled externally, it can also be used as an automatically controlled orin (Buddhist bell), and there are no restrictions on its application or usage. [Brief explanation of the drawing]

[0013] [Figure 1] Example 1 of the sound-producing device is shown. [Figure 2] An example of the sound-producing device, Example 2, is shown. [Figure 3] Example 3 of the sound-producing device is shown. [Figure 4] An example of combining the sound-producing device according to the present invention with a levitation device is shown.

Best Mode for Carrying Out the Invention

[0014] A configuration example of the sound emitting device according to the present invention will be described based on the drawings. FIG. 1 shows Example 1, in which a vibration unit 13 is provided inside an electronically controlled vibration base 12, and a sound emitting unit 11 is placed on the vibration unit 13. In this embodiment, the shape of the sound emitting unit 11 is an example of a substantially bowl shape, but there is no particular limitation as long as it has a bottomed structure and the side wall portion becomes an antinode of vibration. By doing so, a conventional o-ring can also be used as the sound emitting unit 11. The vibration unit 13 of the vibration base 12 is controlled by an external signal. By placing various sound emitting units 11 on this and applying vibrations with a frequency that matches the natural vibration of the sound emitting unit, a sound is emitted. In addition, various accessory functions such as communication means with the outside and a timer can also be provided in the vibration base 12.

[0015] FIG. 2 shows Example 2. This embodiment shows an example in which a vibration unit 14 is integrally formed at the bottom of the sound emitting unit 11. The vibration unit 14 is mounted on an IC chip and can be operated and controlled by an external signal. By doing so, for example, as shown in FIG. 4, using the floating device 20 described in Patent Document 2 previously proposed by the present applicant, the sound can be emitted by an external signal while floating the sound emitting unit 11. In order to float the sound emitting unit 11 in the air, a magnet on which a floating force acts due to the magnetic force from the floating device 20 is required. Therefore, the vibration unit 16 is provided with this magnet function and a vibrator. In addition, since this vibration unit 16 has a magnet function and can also be realized, for example, by magnetically applying a vibration signal from the floating device to the magnetic field in the floating device, a simple mechanism can be used.

[0016] FIG. 3 shows Example 3. This is an example in which the vibration unit 15 is erected in the center of the bottom inside of the sound-generating unit 11. In this way, the sound-producing unit 11 is vibrated on the vibration platform 12, and while the sound is being produced, the vibration unit 15 can be grasped with the fingertips and lifted, allowing it to be moved to the required location. For example, there are no particular limitations on the means of moving it without stopping the sound, such as setting it upright with a long, easy-to-hold handle. [Explanation of symbols]
