Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a sound generator that generates a sound by beating.

When a tuning fork with a pair of vibrating bars bent in a U-shape and a handle attached to a curved part strikes the tip of the vibrating bars, the frequency of the upper sound disappears and the basic sound consisting of a predetermined frequency rang for a long time. It is done.
However, it is not a thing to enjoy the timbre because it is only a sound consisting of a fixed frequency (frequency).
In addition, although a tuning fork with a resonance box is known, it can not be said that it is excellent in design.

  Patent Document 1 discloses a sanukite multiple acoustic plate having a plurality of protruding rod-like sounding members. However, the igneous rock is used as a percussive instrument, and the timbre does not always sound long.

  An object of the present invention is to provide a sound generator that generates different timbres depending on the position where the sound is produced, and emits a large sound just by lightly sounding.

A sounding body according to the present invention includes a plurality of pairs of vibrating bars disposed opposite to each other, and an amplification vibrating body for amplifying the vibration of the vibrating bars, and a base in which root sides of the plurality of vibrating bars are connected. And the amplified vibration body by a vibration transmission unit.
Here, it is preferable that the pair of vibrating bars disposed opposite to each other are lateral vibration in which free end portions are mutually spread, and the vibration transmitting portion transmits the lateral vibration as longitudinal vibration to the amplification vibrating body. .
In this case, in the plurality of pairs of vibrating bars, the fundamental sounds of one pair of vibrating bars and the fundamental sounds of the other pair of vibrating bars are different from each other.

Here, the pair of vibrating bars is connected at the base side to the base side which is the opposite side of the free end serving as the vibrating portion disposed to face each other.
The direction in which the opposing vibration portion vibrates is expressed as transverse vibration, and the vibration in a direction orthogonal thereto is expressed relatively as longitudinal vibration.
The sound of horizontal vibration and vertical vibration is in harmony.

In the present invention, the amplification and vibration body is one in which the lateral vibration of the pair of vibrating bars is transmitted through the transmission portion and vibrates in the vertical direction.
There is no limitation on the shape of the amplification vibrator, such as block, box, and plate.
For example, in the case of a plate-like self-supporting type, vibration is transmitted to the table, table or the like by placing it on a table, table or the like, resulting in a louder sound.
In this case, since the amplification vibrator plays a role of transmitting the vibration to a table, a table or the like, the shape may be small.
In addition, when the amplification vibration body is formed into a large plate shape or box shape, the amplification vibration body itself becomes a loud sound.

In the sounding body according to the present invention, since different timbres are generated for a plurality of pairs of vibrating bars, by changing the vibrating bars to be struck, sounds of different frequencies are generated and it can be enjoyed.
In addition, a scale can be formed by combining a plurality of vibration piece pairs.

(A) is a perspective view of the sound generator according to the present invention, (b) is a plan view, and (c) is a side view. The example which made the vibration piece a substantially L-shape is shown. The example which made the vibration piece a substantially U-shape is shown.

The sound generator according to the present invention has no limitation on the number of pairs as long as a plurality of combinations of pairs of opposing vibrating bars are formed.
In the following, a sounding body having two pairs of opposing vibration pieces will be described as an example.
In FIG. 2, the first vibrating bar pair 3a, 3b bent in a substantially U-shape and the second vibrating bar pair 4a, 4b are arranged to cross each other, and the root sides of these vibrating bars are arranged in one base 2b. It is an example connected.
The base portion 2 b is connected to be able to transmit vibrations by means of the plate-like amplified vibrating body 1 and the column-like vibration transmitting unit 2.
The lower end 2 a of the vibration transfer unit 2 is connected at the central portion of the amplification vibrating body 1 in the present embodiment.
The size and shape of the amplification vibrator 1 are set in accordance with the degree of amplification of vibration.
The first and second vibrating bars, the vibration transmitting unit 2 and the amplification vibrating body 1 are preferably made of metal, and different metals or the same metal may be used.
Specifically, copper alloy, aluminum alloy, steel etc. may be mentioned as an example.

First vibrating bar pair 3a, the frequency _{f 1} of 3b, the second vibrating bars paired 4a, unlike frequency _{f 2} of 4b, timbre changes in which one hit.
These lateral vibrations are transmitted to the plate-like amplified vibrating body 1 as the vibrations f in the longitudinal direction via the vibration transmitting unit 2.
Depending on the length, width, thickness and material of the vibrating portion (free end side) constituting the vibrating reed pair, the frequency at which the sound having the frequency to be the basic sound is generated is determined.
FIG. 2 shows an example bent in a substantially L-shape, and FIG. 3 shows an example formed in a substantially U-shape.
FIG. 2 shows an example in which a pair of vibrating bars (vibrating portions) (13a, 13b) and another pair of vibrating bars (14a, 14b) have different widths. May be different.
FIG. 3 shows an example in which the pair of vibrating bars (23a, 23b) and the other pair of vibrating bars (24a, 24b) are substantially U-shaped, but even if the bending length on the free end side is changed Good.
Further, for example, three pairs of vibrating bars may be arranged in a hexagonal shape in plan view, or the distance between the paired vibrating bars may be changed for each pair.
When such a sounding body is placed on a table or the like, the amplified vibration member may be transmitted to the table or the like to make a louder sound.
