This loudspeaker system is provided with: a housing (1a) formed vertically long; a loudspeaker unit (2a) that is provided to the front surface of the housing (1a); a port (3a) that is provided in the top surface of the housing (1a); and a port (5a) that is provided in the bottom surface of the housing (1a).
Description
この発明は、例えばオーディオ信号を再生するスピーカシステムに関する。
The present invention relates to a speaker system for reproducing an audio signal, for example.
トールボーイ型のように縦長の長尺筐体を用いるスピーカシステムでは、天板と底板にスピーカユニットの背圧が反射し、筐体内に定在波が発生する。この定在波は、音圧のピークディップを発生させるため、音質劣化の原因となる。そこで、従来から、筐体内に吸音材を貼り付けることで、又は、筐体内に吸音棒を設けることで、定在波を低減させている（例えば特許文献１参照）。
In a speaker system using a vertically long casing such as a Tallboy type, the back pressure of the speaker unit is reflected on the top plate and the bottom plate, and a standing wave is generated in the casing. Since this standing wave generates a peak dip in sound pressure, it causes deterioration in sound quality. Therefore, conventionally, standing waves are reduced by attaching a sound absorbing material in the housing or by providing a sound absorbing rod in the housing (see, for example, Patent Document 1).
しかしながら、従来構成では、吸音材又は吸音棒を筐体内に別途設ける必要があるため、コストが増大するという課題がある。
However, the conventional configuration has a problem that the cost increases because it is necessary to separately provide a sound absorbing material or a sound absorbing rod in the housing.
この発明は、上記のような課題を解決するためになされたもので、追加部材を設けずに、定在波を低減できるスピーカシステムを提供することを目的としている。
The present invention has been made to solve the above-described problems, and an object thereof is to provide a speaker system capable of reducing standing waves without providing an additional member.
この発明に係るスピーカシステムは、長尺に構成された筐体と、筐体の幅広面のうちの一面に設けられたスピーカユニットと、筐体の幅狭面のうちの一方の面に設けられた第１ポートと、筐体の幅狭面のうちの他方の面に設けられた第２ポートとを備えたことを特徴とする。
A speaker system according to the present invention is provided on one of a long housing, a speaker unit provided on one of the wide surfaces of the housing, and a narrow surface of the housing. And a second port provided on the other of the narrow surfaces of the housing.
この発明によれば、上記のように構成したので、追加部材を設けずに、定在波を低減できる。
According to the present invention, since it is configured as described above, standing waves can be reduced without providing additional members.
以下、この発明の実施の形態について図面を参照しながら詳細に説明する。

Embodiment 1 FIG.
1 is a cross-sectional view showing a configuration example of a speaker system according to Embodiment 1 of the present invention.
The speaker system is a bass reflex type speaker, and reproduces an audio signal, for example. In this speaker system, as shown in FIG. 1, a
また、筐体１ａの天面（幅狭面）には、ポート（第１ポート）３ａが設けられている。また、ポート３ａの外側（筐体１ａの天面）には、ポート３ａに連通した空室（第１空室）４ａが設けられている。空室４ａの容積は、ポート３ａの容積よりも小さい。また、空室４ａは、放射穴（第１放射穴）４１ａを有している。放射穴４１ａの面積は、ポート３ａが有する穴３１ａの面積よりも小さい。なお図１では、放射穴４１ａは、放射穴４１ａから放射される放射音の進行方向がスピーカユニット２ａから放射される放射音の進行方向と同一となる位置に配置されている。
Also, a port (first port) 3a is provided on the top surface (narrow surface) of the housing 1a. In addition, a vacant room (first vacant room) 4a communicating with the port 3a is provided outside the port 3a (the top surface of the housing 1a). The volume of the empty chamber 4a is smaller than the volume of the port 3a. The vacant chamber 4a has a radiation hole (first radiation hole) 41a. The area of the radiation hole 41a is smaller than the area of the hole 31a of the port 3a. In FIG. 1, the radiation hole 41a is arranged at a position where the traveling direction of the radiated sound radiated from the radiating hole 41a is the same as the traveling direction of the radiated sound radiated from the speaker unit 2a.
また、筐体１ａの底面（幅狭面）には、ポート（第２ポート）５ａが設けられている。また、ポート５ａの外側（筐体１ａの底面）には、ポート５ａに連通した空室（第２空室）６ａが設けられている。空室６ａの容積は、ポート５ａの容積よりも小さい。また、空室６ａは、放射穴（第２放射穴）６１ａを有している。放射穴６１ａの面積は、ポート５ａが有する穴５１ａの面積よりも小さい。なお図１では、放射穴６１ａは、放射穴６１ａから放射される放射音の進行方向がスピーカユニット２ａから放射される放射音の進行方向と同一となる位置に配置されている。
Further, a port (second port) 5a is provided on the bottom surface (narrow surface) of the housing 1a. In addition, a vacant room (second vacant room) 6a communicating with the port 5a is provided outside the port 5a (the bottom surface of the housing 1a). The volume of the empty room 6a is smaller than the volume of the port 5a. Moreover, the empty room 6a has a radiation hole (second radiation hole) 61a. The area of the radiation hole 61a is smaller than the area of the hole 51a of the port 5a. In FIG. 1, the radiation hole 61a is disposed at a position where the traveling direction of the radiated sound radiated from the radiating hole 61a is the same as the traveling direction of the radiated sound radiated from the speaker unit 2a.
このスピーカシステムでは、スピーカユニット２ａからの背圧が、ポート３ａ，５ａ及び空室４ａ，６ａを通り、放射穴４１ａ，６１ａから放射される。
このように、実施の形態１に係るスピーカシステムでは、スピーカユニット２ａからの背圧が反射する天面と底面にポート３ａ，５ａを設けることで、背圧が筐体１ａの外部に放射されるため、筐体１ａの内部で反射することはなく、定在波を低減できる。その結果、音圧のピークディップを低減でき、音質の劣化を抑制できる。 In this speaker system, the back pressure from thespeaker unit 2a is radiated from the radiation holes 41a and 61a through the ports 3a and 5a and the vacancies 4a and 6a.
As described above, in the speaker system according to Embodiment 1, the back pressure is radiated to the outside of thehousing 1a by providing the ports 3a and 5a on the top and bottom surfaces where the back pressure from the speaker unit 2a is reflected. Therefore, it is not reflected inside the housing 1a, and standing waves can be reduced. As a result, the peak dip of sound pressure can be reduced and deterioration of sound quality can be suppressed.
このように、実施の形態１に係るスピーカシステムでは、スピーカユニット２ａからの背圧が反射する天面と底面にポート３ａ，５ａを設けることで、背圧が筐体１ａの外部に放射されるため、筐体１ａの内部で反射することはなく、定在波を低減できる。その結果、音圧のピークディップを低減でき、音質の劣化を抑制できる。 In this speaker system, the back pressure from the
As described above, in the speaker system according to Embodiment 1, the back pressure is radiated to the outside of the
また、筐体１ａの天面及び底面にポート３ａ，５ａを設けた場合、ポート３ａ，５ａの方向が試聴方向（スピーカユニット２ａによる放射音の進行方向）とは異なるため、低音が遅れて出てしまう。それに対し、実施の形態１に係るスピーカシステムでは、ポート３ａ，５ａの外側に、ポート３ａ，５ａよりも容積の小さい空室４ａ，６ａを設け、且つ、空室４ａ，６ａに、ポート３ａ，５ａが有する穴３１ａ，５１ａよりも面積の小さい放射穴４１ａ，６１ａを設けている。これにより、放射穴４１ａ，６１ａからの放射音（ポート音）は、加速されて放射される。その結果、放射音の応答性を改善できる。
In addition, when the ports 3a and 5a are provided on the top and bottom surfaces of the housing 1a, the direction of the ports 3a and 5a is different from the listening direction (the direction of sound emitted by the speaker unit 2a), so that the bass is delayed. End up. On the other hand, in the speaker system according to Embodiment 1, the vacant chambers 4a and 6a having a smaller volume than the ports 3a and 5a are provided outside the ports 3a and 5a, and the vacant chambers 4a and 6a have the ports 3a and 6a. Radiation holes 41a and 61a having a smaller area than holes 31a and 51a of 5a are provided. Thereby, the radiated sound (port sound) from the radiation holes 41a and 61a is accelerated and radiated. As a result, the responsiveness of the radiated sound can be improved.
以上のように、この実施の形態１によれば、縦長長尺に構成された筐体１ａと、筐体１ａの前面に設けられたスピーカユニット２ａと、筐体１ａの天面に設けられたポート３ａと、筐体１ａの底面に設けられたポート５ａとを備えたので、追加部材を設けずに、定在波を低減できる。
As described above, according to the first embodiment, the vertically long casing 1a, the speaker unit 2a provided on the front surface of the casing 1a, and the top surface of the casing 1a are provided. Since the port 3a and the port 5a provided on the bottom surface of the housing 1a are provided, standing waves can be reduced without providing an additional member.

このように、ポート３ａとポート５ａの長さを変えることで、ポート音の共振周波数を変えることができる。よって、放射音の音声帯域を広げることが可能となる。 Embodiment 2. FIG.
FIG. 2 is a cross-sectional view showing a configuration example of a speaker system according to Embodiment 2 of the present invention. The speaker system according to the second embodiment shown in FIG. 2 is different from the speaker system according to the first embodiment shown in FIG. 1 in the lengths of theport 3a and the port 5a.
