Description
本発明は、呼び鈴，警報ベル及びドアベル等、広い分野にて利用できるベルに関する。 The present invention relates to a bell that can be used in a wide range of fields, such as a doorbell, an alarm bell, and a doorbell.
従来のベルは、りん部をりん棒等で打鈴することで鳴るもの、吊り下げた打鈴球が揺れりん部に当たることで鳴るものであった。
また、弾性体で支持された打鈴部の揺動や電気磁石等にて打鈴部を揺動させることで鳴るベルも公知である。
例えば、特開２００３−３２７６７号公報（特許文献１）には、無線による呼び鈴を開示するが、これも負荷コイルを用いたものである。
Conventional bells sounded by hitting the phosphorus part with a rind rod or the like, and ringing when the suspended hitting ball hit the rocking part.
A bell that rings by swinging the hitting bell supported by an elastic body or by swinging the hitting bell with an electric magnet or the like is also known.
For example, JP 2003-32767 A (Patent Document 1) discloses a wireless doorbell, which also uses a load coil.
本発明は、打鈴球や打鈴棒等の打鈴部材の不要なベルの提供を目的とする。 An object of the present invention is to provide a bell that does not require a hitting bell member such as a hitting ball or a hitting bell.
本発明に係るベルは、ベース部と、当該ベース部に支持されたりん部を有し、ベース部はりん部に打鈴することなく加振する加振部を有し、加振部はりん部の有する固有振動数に合致するように加振制御されていることを特徴とする。
これにより、従来の打鈴では発生しやすかったりん部の固有振動数以外の音が、本発明に係るベルではそれが少ない鳴り音となる。
The bell according to the present invention has a base part and a phosphorus part supported by the base part, the base part has a vibration part that vibrates without hitting the phosphorus part, and the vibration part is a phosphorus part. Excitation control is performed so as to match the natural frequency of the part.
As a result, sounds other than the natural frequency of the hook portion that are likely to occur in the conventional hitting bell become less audible sounds in the bell according to the present invention.
ここで、りん部の有する固有振動数は、例えば図２のグラフに示すように加振周波数に対するその時の音圧レベルを測定することで、容易に得られる。
なお、図２に示した３つの音圧ピークは、左側から順に１次(2.36kHz)，２次(6.35kHz)，３次(11.48kHz)の固有振動数が現れている。
Here, the natural frequency of the phosphorus portion can be easily obtained by measuring the sound pressure level at that time with respect to the excitation frequency, for example, as shown in the graph of FIG.
In addition, the three sound pressure peaks shown in FIG. 2 show the natural frequencies of the first order (2.36 kHz), the second order (6.35 kHz), and the third order (11.48 kHz) in order from the left side.
本発明で、ベース部はベース部の揺動を感知するための揺動感知部を有し、
ベース部が揺動すると加振部が作動するように自動制御されていてもよい。
このようにすると、ベース部を軽く左右に揺動するだけでベルが鳴る。
In the present invention, the base portion has a swing sensing portion for sensing the swing of the base portion,
The vibration control unit may be automatically controlled to operate when the base unit swings.
If it does in this way, a bell will ring only by rocking a base part lightly from side to side.
本発明で、加振部は外部のリモートコントローラにて作動可能にしてもよい。 In the present invention, the vibration unit may be operable by an external remote controller.
また、ベース部はりん部の振動レベルを検知するためのピックアップ部を有し、これにより加振部がフィードバック制御されていてもよい。 Further, the base part may have a pickup part for detecting the vibration level of the phosphorus part, and the excitation part may be feedback controlled by this.
本発明に係るベルは、加振部がりん部の有する固有振動数に合せて加振し、又は広帯域入力の一部をフィルタリングすることで、特定の固有振動数による振動音が優位に発生し、固有振動数以外の振動音が少ない音色になる。 In the bell according to the present invention, the vibration part vibrates according to the natural frequency of the phosphorus part or filters a part of the broadband input, so that vibration sound with a specific natural frequency is generated predominately. A tone with less vibration noise than the natural frequency is obtained.
本発明に係るベル１０の構造例を図面に基づいて説明するが、本実施例に限定されるものではない。
ベル１０は、ベース部１１とこのベース部１１に支持部１３を介して支持されたりん部１２とからなる。
図１（ａ）は、釣鐘形状のりん部の内側に支持部１３を設けた例で、（ｂ）はりん部１２の外側に支持部１３を設けた例を示すが、りん部が共鳴部として鳴るものであれば支持形態に制限がない。
また、りん部の形状も釣鐘形状に限定されるものではない。
りん部の材質は黄銅，鉄，ＳＵＳ等の金属製が好ましい。
A structural example of the bell 10 according to the present invention will be described based on the drawings, but is not limited to the present embodiment.
The bell 10 includes a base portion 11 and a phosphorus portion 12 supported by the base portion 11 via a support portion 13.
FIG. 1A shows an example in which a support portion 13 is provided inside a bell-shaped phosphorus portion, and FIG. 1B shows an example in which a support portion 13 is provided outside the phosphorus portion 12. As long as it sounds, there is no limitation on the support form.
Further, the shape of the phosphorus portion is not limited to the bell shape.
The material of the phosphorus portion is preferably made of a metal such as brass, iron, or SUS.
ベース部１１は、図１（ａ）に示すように加振部１４を有し、この加振部１４の位置はりん部１２の内側でも外側でもよい。
ベース部１１の内部に加振部１４の電源部や制御部を設けてある。
ベース部１１は、いろいろな場所に載置できる形状になっていて、ベース部１１を左右に軽く揺動させると、その揺れを揺動感知部が感知し、加振部１４が作動するようになっている。
なお、加振部１４を外部のリモートコントローラでＯＮ／ＯＦＦさせてもよい。
また、図１（ｂ）に示すベルは、ベース部１１にりん部の振動レベルを検知するピックアップ部１５を設けることで、加振部のフィードバック自動調整可能にした例である。
As shown in FIG. 1A, the base portion 11 has a vibration portion 14, and the position of the vibration portion 14 may be inside or outside the phosphorus portion 12.
A power supply unit and a control unit for the vibration unit 14 are provided inside the base unit 11.
The base part 11 has a shape that can be placed in various places, and when the base part 11 is slightly swung left and right, the swing sensing part senses the swing and the excitation part 14 is activated. It has become.
The vibration unit 14 may be turned on / off by an external remote controller.
Further, the bell shown in FIG. 1B is an example in which the pickup unit 15 for detecting the vibration level of the phosphorus portion is provided in the base portion 11 so that the feedback unit can be automatically adjusted for feedback.
加振部１４は、図２のチャートに示したように測定結果にて得られた音圧ピークに合せて、例えば２．３６ｋＨｚ（１次の固有振動数）の近く（±５％）に合せて設計すればよいので、コンパクトで簡単な回路設計でよい。 As shown in the chart of FIG. 2, the vibration unit 14 is matched with the sound pressure peak obtained from the measurement result, for example, close to 2.36 kHz (primary natural frequency) (± 5%). Therefore, a compact and simple circuit design is sufficient.
