れていた。 That is, a bass speaker 4 is attached to the front load horn 1 of the cabinet 3 which has a front load horn 1 and a bass reflex port 2 on the front, a sound absorbing material 5 is housed inside the cabinet 3, and the ceiling of the cabinet 3 is The horn tweeter 6 was arranged on the surface with a support 7 interposed therebetween.
この構成で低音用スピーカ４とホーンツイータ
６とはある距離をもつて位置しており、このため
音圧周波数特性上、クロスオーバー付近でそれぞ
れ距離差による位相のずれを起し、ピークやデイ
ツプがしばしば発生していた。 In this configuration, the bass speaker 4 and the horn tweeter 6 are located at a certain distance, and due to the sound pressure frequency characteristics, a phase shift occurs near the crossover due to the distance difference, resulting in peaks and dips. It happened often.

るものである。 The present invention eliminates the above-mentioned conventional drawbacks, and by improving the cabinet, it prevents the occurrence of peaks and dips in the vicinity of the crossover in the sound pressure frequency characteristics, resulting in flat characteristics. The present invention aims to provide a speaker device that can.

とを特徴とするものである。 That is, in the present invention, the ceiling surface of the cabinet is used as a part of the front load horn, a step section is provided on the rear side of this ceiling surface that projects upward, and a bass speaker is attached to this step section and placed on the ceiling surface. It is characterized by being placed close to the horn tweeter to flatten the sound pressure frequency characteristics near the crossover.
以下、本発明の一実施例を図面第３図、第４図
により説明する。 An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.
８は木材、合成樹脂あるいは金属よりなるキヤ
ビネツトで、このキヤビネツト８の前面にはフロ
ントロードホーン９とバスレフポート１０が設け
られている。 A cabinet 8 is made of wood, synthetic resin, or metal, and a front load horn 9 and a bass reflex port 10 are provided on the front surface of the cabinet 8.
上記フロントロードホーン９はキヤビネツト８

ロントロードホーン９の一部を構成し、このフロ
ントロードホーン９の内端に相当する天井面の部
分には上方に突出する段部１１が形成されてい
る。 The front load horn 9 above is the cabinet 8.
The ceiling surface of the cabinet 8 provided on the upper part of the front load horn 9 constitutes a part of the front load horn 9, and a stepped portion 11 projecting upward is formed in a portion of the ceiling surface corresponding to the inner end of the front load horn 9. ing.
この段部１１には低音用スピーカ１２が取付け
られている。 A bass speaker 12 is attached to this stepped portion 11.
また、このキヤビネツト８内にはグラスウール
などの吸音材１３が収納されている。 Further, a sound absorbing material 13 such as glass wool is housed within the cabinet 8.
そして、上記キヤビネツト８の天井面の上部に
はホーンツイータ１４が上記段部１１を用いて水
平となるように取付けられている。 A horn tweeter 14 is mounted horizontally on the upper part of the ceiling surface of the cabinet 8 using the stepped portion 11.
このように構成することにより低音用スピーカ
１２とホーンツイータ１４とはきわめて接近させ

ロスオーバーでの平坦な再生も可能となり、低高
音間の音源も同一部分より放射されることになり
従来のように低高音がばらばらに再生されるとい
つたことも阻止でき、より忠実な再生が可能とな
る。 With this configuration, the bass speaker 12 and the horn tweeter 14 can be placed extremely close to each other, and since both are assembled with the stepped portion 11 as a reference, the positioning of the vibration system of each speaker in the depth direction is also accurate. The sound pressure frequency response also enables flat reproduction with crossover, and the sound source between low and high frequencies is also radiated from the same part, which prevents low and high frequencies from being played disjointedly as in the past. , more faithful playback is possible.
以上のように本発明のスピーカ装置は低音用ス

利点をもち、工業的価値の大なるものである。 As described above, in the speaker device of the present invention, the bass speaker and the horn tweeter are arranged close to each other, and their mounting position is also determined by the stepped part of the cabinet, so the sound source position is also constant, and the sound pressure frequency characteristics are The characteristics near the crossover can be made extremely stable and flat, making high-fidelity reproduction possible.Furthermore, this stepped section can also support the horn tweeter, which has the advantage of reducing the number of components. It has great industrial value.
