本発明はリング状平板形振動板を低音用スピーカに使っ
た同軸形スピーカに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coaxial speaker using a ring-shaped flat plate diaphragm as a bass speaker.
従来から用いられている同軸形スピーカはコーン形低音
用スピーカの中央部にコーン形、あるいはホーン形の高
音用スピーカが取り付けられていた。Conventionally used coaxial speakers include a cone-shaped bass speaker and a cone-shaped or horn-shaped treble speaker attached to the center of the speaker.
同軸形スピーカは低音用スピーカと高音用スピーカが同
一軸上にあるため、音の方向感や音像が明確になるとい
う利点を有している。Coaxial speakers have the advantage that the bass speaker and the treble speaker are on the same axis, making the sense of sound direction and sound image clear.
しかし、従来の同軸形スピーカは、コーン形低音用スピ
ーカの中央部に取り付けられた高音用スピーカからの音
の放射が低音用スピーカの振動板及びエツジにより反射
されるため、干渉を起こし、主に高音用スピーカの音圧
−周波数特性にピーク、ディップを起こしていた。However, with conventional coaxial speakers, the sound radiation from the treble speaker attached to the center of the cone-shaped bass speaker is reflected by the diaphragm and edges of the bass speaker, causing interference. Peaks and dips were occurring in the sound pressure-frequency characteristics of the high-pitched speaker.
さらに低−音用スピーカ自身にとっても、中央部に高音
用スピーカが突起物として存在するため、音質的にも悪
影響を及ぼしていた。Furthermore, the presence of the high-pitched speaker as a protrusion in the center of the low-pitched speaker itself had an adverse effect on sound quality.
本発明による同軸形スピーカは、このような実情に鑑み
てなされたもので、低音用スピーカに、リング状平板の
振動板を用い、上記低音用スピーカの中央部で、しかも

特性を良好にする他、高音用スピーカの能率を高いもの
にし、更に、低音用スピーカの振動板背面からの空気逃
げを大きくする。The coaxial speaker according to the present invention was made in view of the above circumstances, and uses a ring-shaped flat plate diaphragm as a bass speaker, and furthermore, the ring-shaped flat plate diaphragm is located in the center of the bass speaker. Because the structure allows the treble speaker to be placed almost flush with the diaphragm of the bass speaker, it not only improves the characteristics of the treble and bass speakers, but also increases the efficiency of the treble speaker. Increase air escape.
等の従来の同軸形スピーカの欠点を除去すると共に、高
音用スピーカの取付を容易にすることを目的とするもの
である。The purpose of this invention is to eliminate the drawbacks of conventional coaxial speakers such as the above, and to facilitate the installation of high-pitched speakers.
以下、図によって詳細に説明する。This will be explained in detail below with reference to the drawings.
第１図は、本発明の一実施例を示すリング状平板形振動
板を用いた低音用スピーカと、コーン形高音用スピーカ
からなる同軸型スピーカの断面図である。FIG. 1 is a sectional view of a coaxial speaker including a bass speaker using a ring-shaped flat diaphragm and a cone-shaped treble speaker according to an embodiment of the present invention.
図中１は、低音用スピーカのリング状平板振動板、２は

した非磁性体（磁性体も可）の取付具である。4.: A columnar support member connected to the inner peripheral side of the ring-shaped flat plate diaphragm 1 and having a receiving part for fixing the inner peripheral edge 6 supporting the diaphragm 1 and press-fitting the high-pitched speaker 9 of the coaxial speaker; 5 is a frame connected to the outer circumferential portion of the ring-shaped flat plate diaphragm 1 and fixing the outer circumferential edge 7 that supports the diaphragm 1;
10 is a damper for increasing the linearity of the vibration system, and 10 is a non-magnetic damper with elasticity that is mounted across the back side of the magnetic circuit section of the treble speaker 9 and the back side of the magnetic circuit section of the bass speaker. It is a mounting tool for a body (magnetic material is also possible).
このように構成された本発明の一実施例では低音用振動
板としてリング状平板を用いているために高音用スピー
カからの音の放射が低音用振動板１で反射されて高音用
スピーカ９の特性を乱していた従来の同軸スピーカの大
きな欠点が解決されるばかりか、低音用スピーカ自身の
特性も平担なものが得られるものである。In one embodiment of the present invention configured in this way, a ring-shaped flat plate is used as the bass diaphragm, so the sound radiation from the treble speaker is reflected by the bass diaphragm 1 and is emitted from the treble speaker 9. Not only does this solve the major drawback of the conventional coaxial speaker, which disrupts the characteristics, but the characteristics of the bass speaker itself can be made even.
更に本発明の実施例では高音形スピーカ９を低音用スピ

音用スピーカが実現できるものである。Furthermore, in the embodiment of the present invention, the treble speaker 9 is inserted into the central opening 3a of the bass speaker from the back side, and the treble speaker 9 is inserted into the central opening 3a of the bass speaker, and the treble speaker 9 is crimped to the support member 4 that fixes the edge 6 of the bass speaker. A magnetic circuit portion that is sufficiently larger than the diameter of the diaphragm can be used in the speaker 9, and a highly efficient high-frequency speaker can be realized.
更には、低音用スピーカとして用いているリング状平板

にも改善されるものである。Furthermore, sound radiation from the back side of the ring-shaped flat plate diaphragm 1 used as a bass speaker is not only emitted from the outside of the voice coil, as seen in conventional cone-shaped speakers, but also from the treble speaker 9. The sound quality is also improved compared to conventional bass speakers by passing through the opening made in the support member 4 that fixes the edge 6 of the bass speaker and passing through the central opening 3a of the magnetic circuit section of the bass speaker. It is something that will be done.
また高音用スピーカ９の磁気回路部裏面と低音用スピー
カの磁気回路部裏面とを弾性を持った取付−具１０でつ
なぎ固定するため、高音用スピーカ９は低音用スピーカ
のエツジ６を固定する支持部材４に常時圧着される。In addition, since the back side of the magnetic circuit section of the treble speaker 9 and the back side of the magnetic circuit section of the bass speaker are connected and fixed using an elastic mounting tool 10, the treble speaker 9 is a support that fixes the edge 6 of the bass speaker. It is constantly crimped to the member 4.
このため、高音用スピーカ９を低音用スピーカの前面か

ツジ６の貼り方、高音用スピーカ９の交換等の工作性が
良好となるものである。Therefore, compared to the method of attaching the treble speaker 9 from the front of the bass speaker, the workability of attaching the inner edge 6 of the bass speaker, replacing the treble speaker 9, etc. is improved.

図ることができる。In addition, with this configuration, the high-pitched speaker 9 can be attached by simply inserting the mounting tool 10 into the central opening 3a of the bass speaker and mounting it by bridging the central opening 3a, which simplifies the installation work. It is easy to assemble, and since the central opening 3a of the bass speaker itself does not require any mounting means for the treble speaker 9, the structure can be simplified.
尚、高音用スピーカ９の磁気回路部と低音用スピーカの
磁気回路部を結ぶ取付具１０は漏洩磁束の関係で非磁性
