Description

本発明は、計器装置及び音響装置に係り、特に、音を発生させる振動板と、背面に前記振動板が搭載される基板と、該基板の正面に配置される計器と、該計器及び前記基板を収容する収容ケースと、該収容ケースの基板側に設けた開口部を覆うカバーとを備えた計器装置及び計器装置に関するものである。   The present invention relates to an instrument device and an acoustic device, and in particular, a diaphragm that generates sound, a substrate on which the diaphragm is mounted on a back surface, an instrument disposed on the front surface of the substrate, the instrument, and the substrate The present invention relates to a measuring instrument device and a measuring instrument device provided with a storing case that stores a cover and a cover that covers an opening provided on the substrate side of the storing case.

一般的に、車両に搭載されるコンビネーションメータなどの計器装置内に備えられた振動板を有するブザーは、計器装置の収容ケース正面に放音孔が設けられている(例えば、特許文献1)。しかしながら、単に収容ケース正面に放音孔を設けるだけの構成では、ブザーからの音圧を効率的に外部に出力することができない。このため、低消費電力の小型ブザーを用いると、十分な音圧を得ることができない。   Generally, a buzzer having a diaphragm provided in an instrument device such as a combination meter mounted on a vehicle is provided with a sound emission hole in front of a housing case of the instrument device (for example, Patent Document 1). However, the configuration in which the sound emitting hole is simply provided in front of the housing case cannot efficiently output the sound pressure from the buzzer to the outside. For this reason, if a small buzzer with low power consumption is used, sufficient sound pressure cannot be obtained.

そこで、ブザーの音圧を上げるために、例えば図7に示すように、ブザー1から出力された音を背面側に設けた共振部材2で共振・反射させてから正面に設けた放音孔3から出力する警報装置も考えられている(特許文献2)。   Therefore, in order to increase the sound pressure of the buzzer, for example, as shown in FIG. 7, the sound output from the buzzer 1 is resonated and reflected by the resonance member 2 provided on the back side, and then the sound emitting hole 3 provided on the front side. Is also considered (Patent Document 2).

しかしながら、上述した警報装置では、ブザー1の背面に共振部材2を設ける必要があり、前後方向Y1の厚みが大きくなり、薄型化を図ることができないという問題があった。

As shown in FIG. 5, one end of the sound introduction path 20 communicates with the resonance space 18 through the communication hole 22. As shown in FIG. 4, the other end of the sound introduction path 20 communicates with the convex portion 19 through the communication hole 23. That is, the sound introduction path 20 connects the resonance space 18 and the sound emission hole 20.

音導入路21は、図3及び図4に示すように、共鳴空間部18を中心として基板11に沿った渦巻き状になるように設けられている。また、音導入路21は、図6に示すように、正面が裏カバー本体15によって形成され、背面がカバー部16によって形成されている。音導入路21は、正面側の側面が裏カバー本体15によって形成され、背面側の側面がカバー部16によって形成されている。   As shown in FIGS. 3 and 4, the sound introduction path 21 is provided in a spiral shape along the substrate 11 with the resonance space 18 as the center. Further, as shown in FIG. 6, the sound introduction path 21 has a front surface formed by the back cover body 15 and a back surface formed by the cover portion 16. The sound introduction path 21 has a front side surface formed by the back cover body 15 and a back side surface formed by the cover portion 16.

音導入路21は、放音孔20が近づくに従ってその断面積が大きくなるように設けられている。即ち、図6において、音導入路21のB−B線での断面積をSB、音導入路21のC−C線での断面積をSC、音導入路21のD−D線での断面積をSD、音導入路21のE−E線での断面積をSE、放音孔20の開口面積をSFとすると、下記の式(1)に示す関係となる。
F>SE>SD>SC>SB …(1)
The sound introduction path 21 is provided so that its cross-sectional area increases as the sound emission hole 20 approaches. That is, in FIG. 6, the cross-sectional area of the sound introduction path 21 along the line BB is S B , the cross-sectional area of the sound introduction path 21 along the line CC is S C , and the sound introduction path 21 is along the line DD. Where S D is the cross-sectional area, S E is the cross-sectional area of the sound introduction path 21 along the line E-E, and S F is the opening area of the sound emission hole 20, the following equation (1) is established.
S F > S E > S D > S C > S B (1)

詳しくは、音導入路21は、図6に示すように、その幅WB〜WDが放音孔20に近づくに従って広くなるように設けて、断面積を大きくしている。音導入路21は、その高さHB〜HDが放音孔20に近づくに従って広くなるように設けて、断面積を大きくしている。また、共鳴空間部18の基板11と直交する方向Y2の高さH(図5)は、音導入路21の高さ(例えばHB〜HD)よりも高くなるように設けられている。 Specifically, as shown in FIG. 6, the sound introduction path 21 is provided so that the widths W B to W D become wider as the sound emission hole 20 is approached, and the cross-sectional area is increased. Sound introduction path 21, the height H B to H D is provided to be wider toward the sound emitting hole 20, and increasing the cross-sectional area. Further, the height H (FIG. 5) of the resonance space 18 in the direction Y2 orthogonal to the substrate 11 is provided to be higher than the height of the sound introduction path 21 (for example, H B to H D ).

上述した計器装置によれば、音導入路21の断面積が放音孔20に近づくに従って大きくなる。これにより、効率的にブザー10の振動板の振動を音響エネルギーに変換することができる。しかも、裏カバー14側面に設けた凸部19の正面に放音孔20を設けている。これにより、音導入路21を基板11に沿って設けることができる。上記基板11は、正面に計器が設けられて関係上ある程度の大きさがある。そして、この基板11に沿って音導入路21を設けることにより、効率的に音響エネルギーに変換するために十分な長さの音導入路21を設けることができ、基板11の背面側のスペースを有効に活用して、音導入路21を設けることができる。従って十分な音圧を得つつ薄型化を図ることができる。   According to the instrument device described above, the cross-sectional area of the sound introduction path 21 increases as it approaches the sound emission hole 20. Thereby, the vibration of the diaphragm of the buzzer 10 can be efficiently converted into acoustic energy. Moreover, a sound emitting hole 20 is provided in front of the convex portion 19 provided on the side surface of the back cover 14. Thereby, the sound introduction path 21 can be provided along the substrate 11. The substrate 11 has a certain size due to the instrument provided on the front. By providing the sound introduction path 21 along the substrate 11, it is possible to provide the sound introduction path 21 having a sufficient length to efficiently convert the sound energy into the acoustic energy. The sound introduction path 21 can be provided by making effective use. Therefore, it is possible to reduce the thickness while obtaining a sufficient sound pressure.

また、上述した計器装置によれば、共鳴空間部18の高さHが、音導入路21の高さよりも大きくなるように設けられているので、基板11と裏カバー14との間の最大高さが、共鳴空間部18の高さHとなるので、より一層薄型化を図ることができる。   Further, according to the instrument device described above, the height H of the resonance space 18 is provided so as to be larger than the height of the sound introduction path 21, so that the maximum height between the substrate 11 and the back cover 14 is increased. However, since the height H of the resonance space 18 is obtained, the thickness can be further reduced.

また、上述した計器装置によれば、音導入路21が、共鳴空間部18を中心とした基板11に沿った渦巻き状になるように設けられているので、基板11のブザー10側のスペースをさらに有効に使用することができ、より一層薄型化を図ることができる。   Moreover, according to the above-described instrument device, the sound introduction path 21 is provided so as to be spiral along the substrate 11 with the resonance space 18 as the center, so that the space on the buzzer 10 side of the substrate 11 is reduced. Furthermore, it can be used effectively and can be further reduced in thickness.

なお、上述した実施形態では、図5に示すように、共鳴空間部18は、その側面がカバー部16及び裏カバー本体15の両者によって形成されていたが、本発明はこれに限ったものではない。例えば、共鳴空間部18としては、その側面がカバー部16のみによって形成されてもよいし、裏カバー本体15のみによって形成されてもよい。   In the above-described embodiment, as shown in FIG. 5, the resonance space portion 18 has the side surface formed by both the cover portion 16 and the back cover body 15, but the present invention is not limited to this. Absent. For example, the resonance space portion 18 may have a side surface formed only by the cover portion 16 or may be formed only by the back cover body 15.

また、上述した実施形態では、図6に示すように、音導入路21は、その側面がカバー部16及び裏カバー本体15の両者によって形成されていたが、本発明はこれに限ったものではない。例えば、音導入路21としては、その側面がカバー部16のみによって形成されてもよいし、裏カバー本体15のみによって形成されてもよい。   In the embodiment described above, as shown in FIG. 6, the side surface of the sound introduction path 21 is formed by both the cover portion 16 and the back cover body 15, but the present invention is not limited to this.
