【０００１】0001
本考案は、スピーカユニツトがキヤビネツト内に組み込まれていて据置型ある いはボツクス型などと称される車載用スピーカに関する。 This invention has a speaker unit built into the cabinet and is a stationary type. The present invention also relates to a car-mounted speaker called a box type speaker.
【０００２】0002
この種の据置型のスピーカは、自動車のリアトレイなどへ容易に取り付けるこ とができ、キヤビネツトに装飾効果をもたせることでデザイン上のメリツトも期 待できるため、車載用として広く普及している。だが、車載用の場合、スピーカ ユニツトを組み込むキヤビネツトの容積を大きくすることができないので、高い 音圧が要求される低音域において良好な再生特性が得られないという難点があつ た。 This type of stationary speaker can be easily attached to the rear tray of a car. It also has design benefits by adding a decorative effect to the cabinet. It is widely used in automobiles because it can last a long time. However, for automotive use, the speaker It is not possible to increase the volume of the cabinet in which the unit is installed, so it is expensive. The problem is that good reproduction characteristics cannot be obtained in the low frequency range where sound pressure is required. Ta.
【０００３】 そこで従来、図２の断面図に示すように、キヤビネツトの底部に通気性を確保 した据置型の車載用スピーカが提案されており、すでに一般に採用されている。 同図に示すスピーカ１は、磁気回路やボイスコイル、振動板等で構成されるスピ ーカユニツト２が、底部に通気穴３ａを開設したキヤビネツト３の内部に組み込 まれており、このスピーカ１を取り付ける際には、上記キヤビネツト３を自動車 の内壁の開口周縁部、通常はリアトレイ４の開口４ａの周縁部に据え付けて、上 記通気穴３ａを開口４ａと対向させる。こうすることで、キヤビネツト３内の空 間が、通気穴３ａおよび開口４ａを介して自動車の後部トランクルームと連通さ れるため、スピーカユニツト２の背面の空間が広がつて高い音圧を発生させるこ とができ、低音再生特性の向上が図れる。なお、同図中の符号５は、リアトレイ ４を支持している自動車の鉄板を示している。0003 Therefore, as shown in the cross-sectional view of Figure 2, conventional methods have been used to ensure ventilation at the bottom of the cabinet. A stationary car-mounted speaker has been proposed and is already in general use. The speaker 1 shown in the figure is a speaker composed of a magnetic circuit, a voice coil, a diaphragm, etc. The cabinet 2 is installed inside the cabinet 3 which has a ventilation hole 3a at the bottom. When installing this speaker 1, connect the cabinet 3 to the car. It is installed around the opening 4a of the inner wall of the The ventilation hole 3a is opposed to the opening 4a. By doing this, the air inside cabinet 3 will be The space communicates with the rear trunk room of the automobile through the ventilation hole 3a and the opening 4a. As a result, the space behind speaker unit 2 expands and high sound pressure is generated. It is possible to improve bass reproduction characteristics. In addition, the code 5 in the same figure is the rear tray. It shows the steel plate of the car supporting 4.

しかしながら上述した従来品は、高い音圧が発生できて低音域の再生に有利で はあるものの、後部トランクルーム等の広い密閉空間をそのまま利用するため、 低音域の振動が長く残つて音質を劣化させやすいという不具合があり、また、車 種や収納する荷物の量によつて後部トランクルーム内で利用できる空間の体積が 変化するため、安定した再生特性が得にくいという不具合もあつた。 However, the conventional products mentioned above can generate high sound pressure and are advantageous for bass reproduction. However, in order to utilize the large enclosed space such as the rear trunk room, There is a problem that vibrations in the low frequency range remain for a long time, easily degrading the sound quality, and The amount of space available in the rear luggage compartment varies depending on the type and amount of luggage stored. There was also a problem that it was difficult to obtain stable playback characteristics because of the change.
【０００５】 本考案はこのような事情に鑑みてなされたもので、その目的は、音質を損なわ ずに安定した低音再生特性が得られる据置型の車載用スピーカを提供することに ある。[0005] This invention was devised in view of these circumstances, and its purpose is to avoid deteriorating the sound quality. We aim to provide a stationary car speaker that provides stable bass reproduction characteristics without any noise. be.

上記した本考案の目的は、底部に通気性が確保されているキヤビネツトの内部 にスピーカユニツトが組み込まれていて、該キヤビネツトを車両の内壁の開口周 縁部に据え付けて使用される車載用スピーカにおいて、上記キヤビネツトの底部 を、通気性を有し音響抵抗の高いフエルト等の吸音材にて蓋閉することによつて 達成される。 The purpose of the invention described above is to A speaker unit is built into the cabinet, and the speaker unit is installed around the opening in the inner wall of the vehicle. For automotive speakers that are installed on the edge, the bottom of the cabinet By closing the lid with a sound-absorbing material such as felt that is breathable and has high acoustic resistance. achieved.
【０００７】[0007]
通気性を有する吸音材を介してキヤビネツト内の空間とその後方の空間とを連 通させると、一方の空間から他方の空間へ伝わる空気振動は弱められるが、連通 させる空間として後部トランクルーム等の広い密閉空間を利用すれば、低音域を 再生するのに必要な音圧を得ることができ、しかもこの広い密閉空間に残留する 弱い空気振動はほとんどキヤビネツト内へ伝わらないので、音質の劣化が防止で きる。 The space inside the cabinet is connected to the space behind it through a breathable sound-absorbing material. When the air is passed through, the air vibrations transmitted from one space to the other are weakened, but the communication If you use a large enclosed space such as the rear trunk room as a space to improve the bass range, It is possible to obtain the sound pressure necessary for playback, and it remains in this large closed space. Almost all weak air vibrations are not transmitted into the cabinet, preventing deterioration of sound quality. Wear.

以下、本考案の実施例を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described based on the drawings.
【０００９】 図１は本考案の一実施例に係る車載用スピーカを自動車のリアトレイに据え付 けた状態を示す断面図であり、先に説明した図２と対応する部分には同一符号が 付してある。[0009] Figure 1 shows an in-vehicle speaker according to an embodiment of the present invention installed in the rear tray of a car. 2 is a sectional view showing a cross-sectional state, and parts corresponding to those in FIG. 2 described above are designated by the same reference numerals. It is attached.
【００１０】 図１に示す据置型のスピーカ１は、スピーカユニツト２を組み込んだキヤビネ ツト３の底部にフエルトからなる吸音材６が付設してあり、この吸音材６によつ てキヤビネツト３の通気穴３ａが蓋閉されている。そして、このスピーカ１を取 り付ける際には、鉄板５に支持されているリアトレイ４の開口４ａに通気穴３ａ を対向させた状態で、キヤビネツト３を該開口４ａの周縁部に据え付けるので、 通気性を有する吸音材６を介してキヤビネツト３内の空間と後部トランクルーム とが連通されることとなる。0010 A stationary speaker 1 shown in Fig. 1 is a cabinet incorporating a speaker unit 2. A sound absorbing material 6 made of felt is attached to the bottom of the tube 3. The ventilation hole 3a of the cabinet 3 is closed. Then, remove this speaker 1. When installing, insert the ventilation hole 3a into the opening 4a of the rear tray 4 supported by the iron plate 5. Since the cabinet 3 is installed on the periphery of the opening 4a with the two facing each other, The space inside the cabinet 3 and the rear trunk room are connected through the breathable sound absorbing material 6. will be communicated with.
【００１１】 このようにキヤビネツト３の底部が吸音材６で蓋閉されていると、該吸音材６ を通過して伝わる空気の振動が弱められるが、後部トランクルームは容積が大き いので、低音域を再生するのに必要な音圧は確保することができる。また、広い 密閉空間には特に低音域の振動が弱化しつつも残りやすいが、後部トランクルー ムに残留する弱い空気振動は吸音材６を通過すると極端に弱められてキヤビネツ ト３内にはほとんど伝わらないので、音質の劣化を防止することができる。[0011] When the bottom of the cabinet 3 is covered with the sound absorbing material 6 in this way, the sound absorbing material 6 The vibrations of the air transmitted through the Therefore, the sound pressure necessary to reproduce the low frequency range can be secured. Also, wide In an enclosed space, vibrations in the low frequency range tend to remain even though they are weakened, but in the rear trunk When the weak air vibrations remaining in the room pass through the sound absorbing material 6, they are extremely weakened and Since almost no signal is transmitted into the channel 3, deterioration of sound quality can be prevented.
【００１２】 つまり、上記実施例は、キヤビネツト３内の空間と後部トランクルームとの間 に、通気性を有し音響材料とも称される吸音材６を介在させることにより、広い 密閉空間に付随する音響上の特性を弱めた状態で該後部トランクルームを利用す るというものであり、その結果、上記したように低音再生特性を向上させつつ音 質改善が図れ、しかも、車種や収納する荷物の量によつて後部トランクルーム内 で利用できる空間の体積が変化しても音響上はさほど影響しなくなるので、常に 安定した再生特性を期待することができる。0012 In other words, in the above embodiment, there is no space between the space inside the cabinet 3 and the rear trunk room. By interposing the sound absorbing material 6, which has breathability and is also called an acoustic material, the The rear luggage compartment can be used with the acoustic characteristics associated with a closed space weakened. As a result, as mentioned above, the bass reproduction characteristics are improved while the sound is improved. In addition, depending on the vehicle type and the amount of luggage to be stored, it is possible to Even if the volume of space available in the Stable playback characteristics can be expected.
【００１３】 なお、上記実施例では吸音材６としてフエルトを用いているが、ほぼ均一な通 気性を有し音響抵抗の高い他の材料、例えばスポンジ等を吸音材６として用いて もよい。[0013] In the above embodiment, felt is used as the sound absorbing material 6, but almost uniform conduction is required. Other materials with high acoustic resistance such as sponge may be used as the sound absorbing material 6. Good too.
【００１４】[0014]
【考案の効果】 以上説明したように本考案による据置型の車載用スピーカは、キヤビネツト内 の空間とその後方の空間との間に通気性を有する吸音材が介在させてあるので、 低音域の再生を可能にしながら音質劣化が防止でき、しかも再生特性が安定する という優れた効果を奏する。[Effect of the idea] As explained above, the stationary car speaker according to the present invention can be installed inside the cabinet. Since a breathable sound absorbing material is interposed between the space and the space behind it, Prevents sound quality deterioration while allowing bass range reproduction, and also stabilizes playback characteristics. It has this excellent effect.
