Description
【考案の詳細な説明】 本考案は、自動車のドアマウント用スピーカに関する。[Detailed explanation of the idea] The present invention relates to an automobile door-mounted speaker.
自動車の開閉するドアに取り付けられるスピーカは、放
音口が自動車内側に露出し、背面はドア内部に位置する
。In a speaker that is attached to a door that opens and closes in a car, the sound emitting port is exposed to the inside of the car, and the back side is located inside the door.
このドアには上下動するガラスが設けられており、その
ガラスとドアとの間にはパツキンが設けられるが、雨水
はこのパツキンを通過してドア内部に入ることがあり、
この場合にはスピーカにその雨水が侵入し、その性能を
損なう場合がある。This door is equipped with a glass that moves up and down, and a gasket is installed between the glass and the door, but rainwater may pass through this gasket and enter the inside of the door.
In this case, the rainwater may enter the speaker and impair its performance.
ところで、近時は自動車用スピーカにおいても高入力、
高音質化が要求されており、このため再生帯域を広範囲
において満足するように低音域、中音域、高音域を各々
分担する複数のスピーカが用いられるが、そこにネット
ワークを設ける場合には、どうしてもスペース的制約か
ら小型となるために高出力時にそのネットワークが発熱
し、焼損を招く場合がある。By the way, recently, high input and
High sound quality is required, and for this reason, multiple speakers are used to handle the bass, midrange, and treble frequencies in order to satisfy a wide range of playback bands. Due to space constraints, the network is made smaller and generates heat during high output, which can lead to burnout.
本考案は以上のような点に鑑みたもので、水のスピーカ
内部への侵入を防止し、しかもスピーカ振動板の振動作

発熱の放熱も行ない得るようにした自動車のドアマウン
ト用スピーカ提供せんとするものである。The present invention was developed in consideration of the above points, and is designed to prevent water from entering the inside of the speaker, and also to radiate heat generated in the network part etc. by air vibration based on the vibration action of the speaker diaphragm. The purpose of this invention is to provide a door-mounted speaker for automobiles.

。Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a waterproof cover 1, the overall shape of which is a bottomed lid with part of the side wall open, and the open part 1a Four mounting holes 1b□ are formed in the mounting collar 1b on three sides except for the mounting collar 1b, and from the inner peripheral edge of the mounting collar 1b to the bottom surface 1C.
The side wall 1d leading to the side wall 1d has a round shape corresponding to the magnetic circuit of the speaker, and a tongue piece 1C1 continuous to the bottom surface 1C is formed on the open side of the bottom surface 1C.
１ｅは取付鍔部１ｂと側壁１ｄとの角部に形成された段
部である。1e is a stepped portion formed at the corner of the mounting collar 1b and the side wall 1d.

なわれる。Figures 2 and 3 show the state in which the waterproof cover 1 shown in Figure 1 is attached to the back of the treble speaker. The bolts 2a are inserted into the mounting holes of the speaker frame 3, and then the mounting holes 1b1 of the waterproof cover 1 are inserted into the bolts 2a, and the screws 4 are tightened.
これによって、グリル２に対してスピーカと防水カバー
１が順に取り付けられる。As a result, the speaker and the waterproof cover 1 are attached to the grill 2 in this order.

部分に位置する。At this time, the stepped portion 1e of the waterproof cover 1 is in close contact with the stepped portion 3a on the periphery of the speaker frame 3 to prevent water from entering, and the bottom portion 1C is made of a vibration absorbing material such as rubber against the outer surface of the magnetic circuit 5. The opening portion 1a is located at the portion of the network 7 that is attached to the grille 2.
このスピーカの取り付けは、自動車ドアに対して矢印方
向Ａを上にして行なわれる。The speaker is attached to the automobile door with arrow direction A facing upward.
従って、自動車のドア内部への浸水は防水カバー１の側
壁１ｄ、底面部１００舌片１Ｃ□、及び段部１ｅによっ
て、スピーカ内部に侵入することが阻止されるようにな
る。Therefore, water entering the inside of the door of the automobile is prevented from entering the inside of the speaker by the side wall 1d of the waterproof cover 1, the tongue piece 1C□ of the bottom part 100, and the step part 1e.
また、スピーカが高入力となった時にはボイスコイル８

外部に放出されるようになる。Also, when the speaker input is high, the voice coil 8
Heat is generated in the diaphragm 9 and the network 7, but the vibration of the diaphragm 9 causes the air behind the diaphragm 9 to vibrate, so that the heat is forcibly released to the outside through the opening 1a of the waterproof cover 1. Become.
このため、防水カバーを取り付けたにも拘らず、小型の
スピーカ及びネットワークであっても高入力を実現する
ことができるようになる。For this reason, even if a waterproof cover is attached, high input can be achieved even with a small speaker and network.
なお、防水カバー１はその材質を若干の可撓性のある合
成樹脂、可撓性のない金属等にすれば良いが、鉄等の磁
性体で形成すれば磁気シールドの作用も果す。The waterproof cover 1 may be made of a slightly flexible synthetic resin, a non-flexible metal, or the like, but if it is made of a magnetic material such as iron, it also functions as a magnetic shield.
