Description

スピーカーシステムの発明である。
It is an invention of a speaker system.

最近、スピーカー分野に関して電磁アクチュエータあるいは超磁歪素子アクチュエータ利用し、従来からの技術であるコーン紙で空気に振動を与えて音を出す理論ではなく、物質に直接振動を与えるところの骨伝導理論スピーカーなるものがあり、物体内部に直接振動を与えて、例えばドアやテーブルなどいろいろな物をスピーカーにしてしまう発明も存在する。

本願発明はこの骨伝導理論のスピーカーシステムに関するものである。
Recently, in the field of speakers, the use of electromagnetic actuators or giant magnetostrictive element actuators has become a bone conduction theory speaker that gives vibration directly to matter, rather than the conventional technique of giving sound to air with cone paper. There is also an invention in which various objects such as doors and tables are used as speakers by directly applying vibrations inside the object.

The present invention relates to a speaker system based on this bone conduction theory.

骨伝導理論スピーカーには、電磁アクチュエータを利用したものと超磁歪素子アクチュエータを利用したものとがあり、この分野の先行技術の中を見る中でひとつの原理に気がつく。これを明確に理論付けして、それに基づいて新たなスピーカーシステムを構築することを課題とする。

その先行技術のシステムは図1上図で示す以下のものとなる。

振動板(4)に固定具(2)を介して設置した発振体(1)の可動部分(3)は、この発振体(1)を接続設置した場所(A)とは異なる振動板(4)の場所(B)に接続されているスピーカーシステム。

この様な構造のものは以下の先行技術で開示されている。

特許文献1 特開2007−19623
振動発生アクチュエータは筐体を介して振動版と固定してあり、可動部分である振動伝達材が直接振動版に接続されている。なお、この文献の請求項2に、板面に対して平行に振動を与える、となっているが、本願発明振動発生システムに於いては振動を与える方向は特定していないのでサンプルとして紹介する。

特許文献2 特開2012−49653で、
超磁歪アクチュエータはブラケットを介して振動版に固定されていて、可動部分であるヘッドは同じく振動版に当接されている。

この先行技術のシステムが具体的にどのように働いているのかを説明する。

まず、発振体(1)への入力信号に応じて可動部分(3)が伸縮する形での運動が発生する。この運動は、可動部分(3)が接続されている振動版(2)の(B)の場所に伝わる。この時、発振体(1)は、固定具を介して振動版(2)の(A)の場所に接続されているので、これら二つの場所(A)と(B)との間の振動版(2)がたわみ伸縮する形で振動が発生することになる。

この先行技術において音質に最も深く関与するのは振動版(4)の形や材質であるが、なかなか良い素材が見つかっていないのが現実の問題である。

なお、発振体(1)とは従来からある電磁アクチュエータあるいは超磁歪素子アクチュエータとする。
There are two types of bone conduction theory speakers, one using an electromagnetic actuator and one using a giant magnetostrictive element actuator, and one of the principles is noticed while looking at the prior art in this field. The task is to make this theorized clearly and to build a new speaker system based on it.

The prior art system is as shown in the upper diagram of FIG.

The movable part (3) of the oscillator (1) installed on the diaphragm (4) via the fixture (2) is different from the place (A) where the oscillator (1) is connected and installed. The speaker system connected to the location (B).

Such a structure is disclosed in the following prior art.

Patent Document 1 JP2007-19623
The vibration generating actuator is fixed to the vibration plate via a housing, and a vibration transmitting material which is a movable part is directly connected to the vibration plate. In addition, in claim 2 of this document, the vibration is applied in parallel to the plate surface, but in the vibration generating system of the present invention, the direction of applying the vibration is not specified, so it is introduced as a sample. .

Patent Document 2 JP 2012-49653 A,
The giant magnetostrictive actuator is fixed to the vibration plate via a bracket, and the head, which is a movable part, is also in contact with the vibration plate.

Explain how this prior art system works specifically.

First, movement is generated in such a manner that the movable part (3) expands and contracts in response to an input signal to the oscillator (1). This movement is transmitted to the location of (B) of the vibrating plate (2) to which the movable part (3) is connected. At this time, since the oscillating body (1) is connected to the location (A) of the vibration plate (2) via a fixture, the vibration plate between these two locations (A) and (B). The vibration is generated in such a manner that (2) bends and expands and contracts.

In this prior art, it is the shape and material of the vibration plate (4) that is deeply involved in the sound quality, but it is a real problem that no good material has been found.

The oscillator (1) is a conventional electromagnetic actuator or giant magnetostrictive element actuator.

上記従来のスピーカーシステムの問題を解決すべく本願発明は図1下図で示すところの、以下のスピーカーシステムを提供する。

振動版(4)に固定具(2)を介して設置した発振体(1)の可動部分(3)は、間にバネ(5)を直列的に介して同じく振動版(4)上の、発振体(1)を接続設置した場所(A)とは異なる場所(B)に接続されていて、発生する振動とバネ(5)との共振作用を利用し得ながら動作するスピーカーシステム。

なお、バネ(5)の代わりに弾性体を使う事も可能である。
In order to solve the problems of the conventional speaker system, the present invention provides the following speaker system as shown in the lower diagram of FIG.

The movable part (3) of the oscillator (1) installed on the vibration plate (4) via the fixture (2) is also on the vibration plate (4) via a spring (5) in series. A speaker system which is connected to a place (B) different from the place (A) where the oscillator (1) is connected and installed, and operates while utilizing the resonance action between the generated vibration and the spring (5).

It is also possible to use an elastic body instead of the spring (5).

バネ(5)の素材や大きさ、形を選択することなどで共振作用を調整し、発生する振動を大きくしたり、周波数特性を改良したり出来るので、振動板の形や材質選びの幅が広くなる。

振動を与えたい物体を直接動かす必要がなく、実際に動くのは可動部分(3)のみで、これらは軽い素材でも良いので、振動を与えたい物体への遠心力は殆どかからず、運動エネルギーの無駄な消費は少ない。

発振体(1)への入力信号がなくなるとバネ(5)の戻る力で、もともと軽い可動部分(3)は直ちに停止するので、入力応答性がきわめて高い。

発振体(1)への入力信号はどのように変化する波形にも対応可能である。

構造が単純なので微小な構造のものから、巨大なものまで、応用利用範囲は広い。

振動の大きさなども自由に設計出来るので、スピーカー分野にとどまらず、振動試験機や、振動機などの分野への応用も可能である。
By selecting the material, size, and shape of the spring (5), the resonance effect can be adjusted to increase the generated vibration and improve the frequency characteristics. Become wider.

It is not necessary to directly move the object to be vibrated, and only the movable part (3) actually moves, and these may be light materials, so there is almost no centrifugal force on the object to be vibrated, and kinetic energy There is little useless consumption.

When the input signal to the oscillating body (1) disappears, the originally movable light part (3) is immediately stopped by the return force of the spring (5), so the input responsiveness is extremely high.

The input signal to the oscillating body (1) can cope with any changing waveform.

Since its structure is simple, it can be used in a wide range of applications, from minute structures to huge structures.

Since the magnitude of vibration can be designed freely, it can be applied not only to the speaker field but also to fields such as vibration testing machines and vibrators.

以下、本願発明の形態を図1下の図に基づいて説明する。

発振体(1)への入力信号に応じて可動部分(3)が伸縮する形の運動が発生する。
この運動は、その先に直列に結合されているバネ(5)の共振作用を得ながら、バネ(5)が接続されている振動版(2)の(B)の場所に伝わる。この時、発振体(1)は、固定具を介して振動版(2)の(A)の場所に接続されているので、これら二つの場所(A)と(B)との間の振動版(2)が、たわみ伸縮する形で振動が場発生することになる。

At this time, since the oscillating body (1) is connected to the location (A) of the vibration plate (2) via a fixture, the vibration plate between these two locations (A) and (B). In (2), the vibration is generated in the form of bending expansion and contraction.
