Description

本発明は高忠実度をはかるためのスピーカーについてである。The present invention relates to a speaker for high fidelity.

従来のダイナミック型のスピーカーはコーン型が多く用いられており、平面型スピーカーは数少ない。しかし、平面型スピーカーにも多くの長所があるが実用化が難しいところがある。Conventional dynamic type speakers are often used in cone type, and there are few flat type speakers. However, although flat speakers have many advantages, they are difficult to put into practical use.

全面平面駆動させ、全面同位相で、同振幅で、ピストン領域を広くする
することを提供する。
コーン型スピーカーは凹んだ形に起因する音圧の乱れの発生で、音場における特有の音色を持ってしまう。現在実用化されている平面型スピーカーには、振動板に複数のボイスコイルを設けて駆動する方式や、振動板の前面にボイスコイルを張り付けて対応する磁場を設けて駆動する方式や、コーンの前面に平面板を設けて平面型スピーカーとしたものなどがある。いづれの方式でも全面駆動するにあって音質、性能上技術的に改良の余地がある。Provided flat diaphragm by a honeycomb shape voice coil bobbin is entirely flat operation, the entire same phase, at the same amplitude, that provides to widen the piston area.
The cone type speaker has a sound pressure disturbance due to the concave shape, and has a specific tone color in the sound field. Flat type speakers that are currently in practical use include a method of driving with a plurality of voice coils on the diaphragm, a method of attaching a voice coil on the front surface of the diaphragm and driving with a corresponding magnetic field, and a cone speaker. There is a flat speaker with a flat plate on the front. There is room for technical improvement in terms of sound quality and performance when using either method for full drive.

A honeycomb having a regular hexagonal voice coil bobbin formed by winding a voice coil in a planar loop in the shape of a honeycomb, and a magnet or a magnetic body provided inside the regular hexagonal voice coil bobbin, and having a honeycomb-shaped integrated mechanism. This is a planar voice coil bobbin, in which planar diaphragms of different members are attached to the respective voice coil bobbins constituting the honeycomb-shaped voice coil bobbin to synthesize appropriate sound quality in sound pressure.

発明の効果The invention's effect

請求項１について説明する。ハニカム形状 ボイスコイルボビン を構成する各ボビン単体ごとに異なる振動板部材を貼り付け、高低速伝達振動板部材と高低伝達損失振動板部材との任意の組み合わせによって、発生する音圧で調合し高速、高損失伝達振動板の最適な音質を合成する平面振動板とすることになる。これは振動板の動きに対して変形しにくい小面積ボビンの集合体としての全面平面駆動の効果である。Claim 1 will be described. Honeycomb shape Different bobbin components are attached to each bobbin that composes the voice coil bobbin, and any combination of high and low speed transmission vibrating plate members and high and low transmission loss vibrating plate compounds is used to mix the sound pressure to generate high speed and high speed. It will be a flat diaphragm that synthesizes the optimum sound quality of the loss transmission diaphragm. This is an effect of the entire plane driving as an assembly of small area bobbins that are not easily deformed by the movement of the diaphragm.

請求項１について本発明を実施するための形態について説明する。正六角形状の熱に強く強度のある紙などの部材を用いたボイスコイルボビンに平面ループ状ボイスコイルを巻く。図１と図２と図５に示すように，前記平面ループ状ボイスコイル（１）を各々の面に巻いた当該正六角形ボイスコイルボビン（３）を集合しハニカム形状とする。このハニカム形状 ボイスコイルボビン（５）は、ハニカム形状の特性を持つ軽くて強い平面型全面駆動する機構となっている。 ハニカム形状に一体化した各々の前記正六角形ボイスコイルボビン（３）の平面ループ状に巻いたコイルの上部と下部とに、ネオジムやフェライト等の磁石（４１）、（４２）などの磁性体を設け、各々に対向する磁石（４３），（４４）の極性をＮとＳ極、またはＳとＮ極と互いに異なるものとする。これによって前記ハニカム形状 ボイスコイルボビン（５）のボイスコイルの中を流れる音信号に対応して振動板を動かす。With respect to claim 1, a mode for carrying out the present invention will be described. A planar loop voice coil is wound on a voice coil bobbin that uses a regular hexagonal shape of a member such as paper that is strong and resistant to heat. As shown in FIGS. 1, 2, and 5, the regular hexagonal voice coil bobbins (3) having the planar loop voice coil (1) wound on each surface are assembled into a honeycomb shape. This honeycomb-shaped voice coil bobbin (5) has a light-weight and strong planar type full-surface driving mechanism having a honeycomb-shaped characteristic. Magnetic materials such as magnets (41) and (42) such as neodymium and ferrite are provided on the upper and lower portions of the coil wound in a plane loop shape of each of the regular hexagonal voice coil bobbins (3) integrated in a honeycomb shape. , The polarities of the magnets (43) and (44) facing each other are different between the N and S poles or the S and N poles. As a result, the diaphragm is moved in response to the sound signal flowing through the voice coil of the honeycomb-shaped voice coil bobbin (5).

請求項１について図８に基づいて説明する。請求項１のハニカム形状 ボイスコイルボビン を構成する各ボビン単体ごとに特性の異なる振動板部材を張り付け、その振動板材料としてＡｌ（５５）、チタン（５６）などの高速伝達低損失部材や、紙（５７）やポリプロピレン（５８）等の内部伝達損失特性の大きい部材などの任意の組み合わせをすることによって、発生する空中での音圧を調合し、高速伝達高損失振動板の最適な組み合わせによる両立する音質を得る平面振動板を合成するものである。これは本発明による全面駆動ハニカム形状ボイスコイルボビンを用いた平面振動板スピーカーの有する機能である。Claim 1 will be described with reference to FIG. A diaphragm member having different characteristics is attached to each bobbin constituting the honeycomb-shaped voice coil bobbin of claim 1, and a high-speed transmission low-loss member such as Al (55) or titanium (56) or a paper ( 57) or polypropylene (58), etc., the sound pressure generated in the air is mixed by using an arbitrary combination of members having large internal transmission loss characteristics, and both are achieved by an optimal combination of high-speed transmission high-loss diaphragms. This is to synthesize a flat diaphragm to obtain sound quality. This is a function of the flat diaphragm speaker using the all-drive honeycomb voice coil bobbin according to the present invention.
