〔産業上の利用分野〕
本考案は、車輛のドア等に本体を埋め込んで使
用するスピーカを取り付けるスピーカに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a speaker whose main body is embedded in a vehicle door or the like.
現在市販されている車載用ドア埋込み型スピー
カでは、ドアの構造上または取付け上の問題から
スピーカの全高を十分とれないため、薄型スピー
カが主流となつており、そのスピーカはドアの内
張りシートに直接取り付けられている。
Currently available on the market, in-vehicle door-embedded speakers cannot have a sufficient overall speaker height due to problems with the structure or installation of the door, so thin speakers have become mainstream, and the speakers are installed directly on the door lining sheet. installed.
スピーカを薄型にするとスピーカ振動板の低域

のスピーカ自体の性能を十分引き出すことができ
ないという欠点があつた。
If the speaker is made thin, the speaker diaphragm cannot maintain the amplitude in the low range, so there is a limit to the low range reproduction, and sufficient low range reproduction cannot be expected. In addition, when attaching a speaker to a door, if it is attached directly to the lining sheet using tapping screws, the bass sound becomes very difficult to hear due to the material of the lining sheet, and the speaker itself has the disadvantage of not being able to bring out its full performance. .
本考案の目的は、スピーカを直接ドアの内張り
に取り付けず、かつ低音域の再生を改善すること
を可能にする車載用スピーカ取付けスペーサを提
供することである。 An object of the present invention is to provide an in-vehicle speaker mounting spacer that makes it possible to improve bass reproduction without directly mounting the speaker on the lining of a door.
上記目的を達成するために、本考案による車載
用スピーカ取付けスペーサは、スピーカを取り付
ける前面板裏面の周囲に沿つて所定の長さのダク

旨とする。
In order to achieve the above object, the in-vehicle speaker mounting spacer according to the present invention has a duct of a predetermined length along the periphery of the back surface of the front plate where the speaker is mounted, and one opening of the duct faces toward the back surface. ,
The gist is that the other mouth is provided toward the front.
スペーサはスピーカのドアへの取付けを容易に
するばかりでなく、低音域の音質を改善する。
The spacer not only makes it easier to attach the speaker to the door, but also improves the sound quality in the bass range.
ダクトは前面板裏面周囲に設けられるから、長
くとることが可能であり、エンクロージヤ内部に
放射された逆相分はダクト内部を通過する間にさ
らに逆相となり、スピーカ前面に放射される低音
と同相となる。 Since the duct is installed around the back of the front panel, it can be made long, and the reverse phase component radiated inside the enclosure becomes further reverse phase while passing through the duct, and the bass sound radiated to the front of the speaker. Becomes the same phase.
以下に、図面を参照しながら、実施例を用いて
本考案を一層詳細に説明するが、それらは例示に
過ぎず、本考案の枠を越えることなしにいろいろ
な変形や改良があり得ることは勿論である。
Hereinafter, the present invention will be explained in more detail using examples with reference to the drawings, but these are merely illustrative and it is understood that various modifications and improvements may be made without going beyond the scope of the present invention. Of course.

る。 FIG. 1 is a perspective view of the in-vehicle speaker mounting spacer according to the present invention, viewed from the back side. Front plate 1
is attached to the vehicle door using screws through the mounting holes 2 provided at the four corners. Reference numeral 3 denotes a speaker mounting hole, and as shown in FIG. 2, a speaker is attached to the spacer through a speaker mounting hole 4 here.
In FIG. 2, 5 represents a speaker, and 6 represents a door lining. A duct 7 of an appropriate length is attached continuously around the back side of the front plate 1, usually covering 3/4 of the circumference, and its entrance 8 is installed on the back side of the front plate 1 and is located inside the door. ing. An outlet 9 of the duct 7 is formed in the front plate 1 and is directed into the vehicle interior.

スピーカに水滴が当ることがない。 A back case 10 can be provided on the back surface of the front plate 1, as shown in FIG. 3, which fits into the front plate 1 and seals all but the speaker mounting port 3 and the outlet 9 of the duct 7. Figure 3 a is a front view, b is a side view seen from the bottom of the figure, c is a side view seen from the right side of the figure, d
is a sectional view taken along the line d-d' of FIG. 3a. When the speaker was attached to the door, raindrops from the door window would hit the speaker, deteriorating the sound quality during long-term use, but with this structure,
Water droplets will not hit the speaker.

同相となつて出口９から放射される。 When the spacer shown in FIG. 1 or 3 is attached to the inner lining 6 of a door, and the speaker 5 is attached and operated, the inside of the door becomes an enclosure for the speaker. Therefore, the bass reproduced from the speaker 5 is radiated to the front of the speaker, but the bass of the opposite phase radiated inside the enclosure enters from the entrance 8 of the duct 7, and becomes further out of phase while passing through the inside of the duct. , and is emitted from the outlet 9 in phase with the bass emitted to the front of the speaker.
