Abstract
Description
【発明の詳細な説明】
産業上の利用分野
本発明は、一般音響機器に適用される角形スピーカの振
動板に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a diaphragm for a rectangular speaker applied to general audio equipment.
従来の技術
従来この種のスピーカ振動板は、第２図のような構造と
なっていた。すなわち、振動板１は、矩形をなすエツジ
になって、フレーム２に接着される構造であった。2. Description of the Related Art Conventionally, this type of speaker diaphragm has a structure as shown in FIG. That is, the diaphragm 1 had a structure in which the diaphragm 1 was bonded to the frame 2 with rectangular edges.
発明が解決しようとする問題点
ところが前者の振動板の構成であると、スピーカとして
組込まれ動作した際、振動板１のエッジ・コーナ部３が
振幅に対してすぐつっばり及び折れが生じ、歪が増加す
るため、信頼性が低下する。Problem to be Solved by the Invention However, if the diaphragm has the former configuration, when the diaphragm is incorporated into a speaker and operated, the edge/corner portion 3 of the diaphragm 1 will become stiff and bent immediately with respect to the amplitude, resulting in distortion. increases, so reliability decreases.
そこで本発明は、振幅に対して、つっばり及び折れが生
じなく、歪が少なくなり信頼性にすぐれた角形スピーカ
の振動板を提供するものである。Accordingly, the present invention provides a diaphragm for a rectangular speaker that does not suffer from stiffness or bending with respect to amplitude, has less distortion, and is highly reliable.
問題点を解決するだめの手段
この問題点を解決するために本発明は、角形振動板のエ
ッジ・コーナ部４ケ所に凹状切り欠けを設け、コーナ部
を空気振動さすため、フレーム２と接着しないものであ
る。Means to Solve the Problem In order to solve this problem, the present invention provides concave notches at four edges and corners of the rectangular diaphragm, and in order to air vibrate the corners, it is not bonded to the frame 2. It is something.
作用
角形スピーカのエッジ・コーナ部が他のエツジ部より早
くつっばりが生じるため、エッジ・コーナ部に凹状切り
欠けを設けることにより、コーナ部がフリーに振幅する
ことが可能であり信頼性に優れている。Since the edges and corners of working rectangular speakers become stiff earlier than other edges, by providing concave notches in the edges and corners, the corners can vibrate freely, resulting in excellent reliability. ing.
実施例
以下本発明の一実施例における角形スピーカの振動板に
ついて説明する。第１図に示すように、角形フレーム２
のコーナ部を省スペースを目的として凸状にし、その上
に４ケ所凹状に切り欠けをつけた角形振動板１を接着さ
せる。EXAMPLE A diaphragm of a rectangular speaker according to an example of the present invention will be described below. As shown in FIG.
The corners of the diaphragm are made convex for the purpose of space saving, and a rectangular diaphragm 1 having four concave notches is adhered thereon.
角形振動板１のエツジコーナ部４ケ所の凹状切り欠は部
４を設けることにより、エツジコーナ部のつっばり、折
れかなくなり大振幅に対する歪が少なくなる。By providing the concave notches 4 at the four edge corners of the rectangular diaphragm 1, the edge corners will not be stiff or bent, and distortion against large amplitudes will be reduced.
発明の効果
以上のように本発明は角形振動板のエツジコーナ部４ケ
所に凹状切り欠けを設けることによりエッジ・コーナ部
のつっばり、折れかなくなり大振幅に対しても歪が少な
くなり、角形振動板の信頼性を高めることが出来る。Effects of the Invention As described above, the present invention provides concave notches at the four edge corners of a square diaphragm, thereby preventing the edges and corners from becoming stiff or breaking, reducing distortion even with large amplitudes, and reducing square vibration. The reliability of the board can be improved.
