Description

スピーカ装置用スタンドSpeaker stand
　この発明は、スピーカ装置用のスタンドに関し、特に筐体内に下向きに設置されたスピーカの音を拡散させるものに関する。 The present invention relates to a stand for a speaker device, and more particularly to a stand for diffusing the sound of a speaker installed downward in a housing.
　従来、筐体内に下向きにスピーカを設置したスピーカ装置が提案されている（例えば、特許文献１，２を参照）。 Conventionally, a speaker device in which a speaker is installed downward in a housing has been proposed (see, for example, Patent Documents 1 and 2).
　これらのスピーカ装置は、スピーカの下に円錐形の反射板が設けられている。スピーカから出た音は、反射板に反射して水平方向に拡散される。これにより、従来のスピーカ装置は、スピーカを下向きに設置した場合であっても、水平方向の全方位に均等に音を出力することができる。 These speaker devices are provided with a conical reflector under the speaker. The sound emitted from the speaker is reflected by the reflecting plate and diffused in the horizontal direction. As a result, the conventional speaker device can output the sound evenly in all directions in the horizontal direction even when the speaker is installed downward.

　しかし、従来のスピーカ装置では、スピーカと反射板との距離が短い場合には音が十分に拡散しないという課題がある。スピーカと反射板との距離をある程度長くすると、スタンドが大型化してしまう。 However, the conventional speaker device has a problem that sound is not sufficiently diffused when the distance between the speaker and the reflector is short. If the distance between the speaker and the reflector is increased to some extent, the stand will be enlarged.
　また、従来のスピーカ装置では、反射板がスピーカからの音圧を全て受けることになり、反射板自体が振動して余分な音が発生する可能性がある。 In the conventional speaker device, the reflection plate receives all the sound pressure from the speaker, and the reflection plate itself may vibrate to generate extra sound.
　また、従来のスピーカ装置は、水平方向に音を拡散させることができるが、下方向には反射板が存在するため、下方向に音を出力することができない。したがって、例えば、筐体を壁面に設置した際には、下方向への音の広がりが少なくなる。 In addition, the conventional speaker device can diffuse sound in the horizontal direction, but cannot output sound in the downward direction because there is a reflector in the downward direction. Therefore, for example, when the casing is installed on the wall surface, the spread of the sound in the downward direction is reduced.
　そこで、この発明は、水平方向に音を十分に拡散させ、かつ下方向にも広がりのある音を出力することができるスピーカ装置用スタンドを提供することを目的とする。 Accordingly, an object of the present invention is to provide a stand for a speaker device that can sufficiently diffuse sound in a horizontal direction and output a sound that spreads downward.
　本発明のスピーカ装置用スタンドは、スピーカ装置(10)の筐体(20)の下側に設けられるスピーカ装置用のスタンド(1)は、前記筐体内に下向きに設置されたスピーカ(50)の下側に前記スタンドが設置された状態で、前記スピーカから放出された音を拡散する拡散部(14)を備え、前記拡散部は、前記放出された音の放音方向に対して傾斜した主面を有する複数の板状部材を備え、前記複数の板状部材のうちの互いに隣り合う２つの板状部材の間に少なくとも１つのスリットが形成されることを特徴とする。 The speaker device stand of the present invention is a speaker device stand (1) provided on the lower side of the housing (20) of the speaker device (10), the speaker device stand (1) of the speaker (50) installed downward in the housing. A diffusion unit (14) for diffusing the sound emitted from the speaker in a state where the stand is installed on the lower side, the diffusion unit being inclined with respect to the sound emission direction of the emitted sound A plurality of plate-like members having a surface are provided, and at least one slit is formed between two plate-like members adjacent to each other among the plurality of plate-like members.
　これにより、スピーカから出力された音は、板状部材の間を抜けて、下方向に拡散することになり、筐体の背面を壁面に設置した場合に下方向への音の広がりを阻害することがない。また、スピーカ装置を床やラック等の水平な設置面に設置した場合でも、板状部材の間を抜けて水平方向に音を拡散することもでき、スピーカと拡散板との距離が短くとも、音が十分に拡散することになる。また、スピーカからの音は、板状部材の間を抜けるため、拡散板がスピーカからの音圧を全て受けることがなく、拡散板自体が振動して余分な音が発生することがない。 As a result, the sound output from the speaker passes through the plate-like members and diffuses downward, which inhibits the downward spread of sound when the back surface of the housing is installed on the wall surface. There is nothing. Moreover, even when the speaker device is installed on a horizontal installation surface such as a floor or a rack, sound can be diffused in the horizontal direction by passing between the plate-like members, and even if the distance between the speaker and the diffusion plate is short, Will diffuse sufficiently. Further, since the sound from the speaker passes through between the plate-like members, the diffusion plate does not receive all the sound pressure from the speaker, and the diffusion plate itself does not vibrate and no extra sound is generated.
　また、拡散板の下側にスペーサを設けることで、拡散板と設置面との間に空間を形成し、当該空間から音を拡散させることが好ましいが、例えば拡散板（または拡散板の回りの枠体）の下面に突起を設けることで設置面との間に空間を形成することも可能である。 In addition, it is preferable to form a space between the diffuser plate and the installation surface by providing a spacer on the lower side of the diffuser plate and diffuse sound from the space. For example, the diffuser plate (or around the diffuser plate) It is also possible to form a space with the installation surface by providing a protrusion on the lower surface of the frame body.
　また、拡散板は、放射状に並べられた複数の板状部材からなることが好ましい。主面が傾斜した板状部材を放射状に並べることで、スピーカから出力された音を均一に周囲に拡散させることができる。 The diffusion plate is preferably composed of a plurality of plate-like members arranged radially. By arranging the plate-like members whose main surfaces are inclined radially, the sound output from the speaker can be uniformly diffused to the surroundings.
　また、前記複数の板状部材は、主面の前記放音方向に対する傾斜度合いが夫々等しく、且つ、主面が互いに離間するように配列されることが望ましい。
　また、前記複数の板状部材の少なくとも１つの主面は、前記スピーカの下側に前記スタンドが設置された状態で、前記スピーカ装置の背面側の部分が欠けた形状を有するものとしても良い。
　また、前記拡散部は、前記筐体の下面から空間を隔てて下方に配置され、前記スピーカ装置用のスタンドは、その側面が開口した状態になっていることとしても良い。
　前記複数の板状部材は、前記複数の板状部材のうちの隣り合う２つの各々の主面が互いに対向するように配置されることとしても良い。
　また、前記複数の板状部材のうちの隣り合う２つは、第１板状部材(141A,141B,141C)と、前記第１板状部材の周囲に配置される環状の第２板状部材(141B,141C,141D)としても良い。
　また、前記複数の板状部材は、各々の上端部が同じ高さとなり、且つ各々の下端部が同じ高さとなるように配列されることとしても良い。
　また、本発明のスピーカシステムは、筐体に収容されたスピーカユニットを備えるスピーカ装置と、前記スピーカユニットの下側に配置された状態で、前記スピーカユニットから放出された音を拡散する拡散部を有する少なくとも１つのスタンドと、を備え、前記拡散部が、前記放出された音の放音方向に対して傾斜した主面をそれぞれが有する、互いに離間して配置された複数の板状部材を備えることとすることができる。 In addition, it is desirable that the plurality of plate-like members be arranged so that the inclination degree of the main surface with respect to the sound emitting direction is equal and the main surfaces are separated from each other.
Further, at least one main surface of the plurality of plate-like members may have a shape in which a portion on the back side of the speaker device is missing in a state where the stand is installed below the speaker.
Moreover, the said spreading | diffusion part is arrange | positioned through the space | interval from the lower surface of the said housing | casing, and it is good also as the stand for the said speaker apparatus being in the state which the side surface opened.

　スピーカ装置１０は、幅方向に長い直方体形状の筐体２０を有している。スピーカ装置１０の下側には、複数（同図においては２つ）のスタンド１が設けられている。 The speaker device 10 has a rectangular parallelepiped casing 20 that is long in the width direction. A plurality of (two in the figure) stands 1 are provided below the speaker device 10.
　スピーカ装置１０は、図１（Ｂ）および図１（Ｃ）に示すように、筐体２０内部にスピーカ(スピーカユニット)５０が設置されている。スピーカ５０は、スタンド１の上側に、放音方向が下向きにして設けられている。このように、筐体２０内部において放音方向が下向きに設置されたスピーカ５０を設けることで、スピーカ装置１０の筐体２０の高さが低く抑えられている。 As shown in FIGS. 1B and 1C, the speaker device 10 has a speaker (speaker unit) 50 installed inside the housing 20. The speaker 50 is provided on the upper side of the stand 1 with the sound emission direction facing downward. As described above, the height of the casing 20 of the speaker device 10 is kept low by providing the speaker 50 in which the sound emission direction is set downward in the casing 20.
　また、スピーカ装置１０は、図１（Ａ）に示すように、筐体２０正面の中央部に複数のスピーカ（この例では８個）が配列されたスピーカアレイ１０１が設置されている。スピーカアレイ１０１の各スピーカから音を出力すると、所定方向に強い指向性を有する音声ビームが形成される。スピーカ装置１０は、各スピーカから出力する音の遅延量を制御することで、音声ビームの方向を制御する。スピーカアレイ１０１の各スピーカは小型であるため、低域（例えば２００Ｈｚ以下）の音を出力することができない。したがって、スピーカ５０は、スピーカアレイ１０１では出力することのできない低域の音を補うために設置されている。 Further, as shown in FIG. 1A, the speaker device 10 is provided with a speaker array 101 in which a plurality of speakers (eight in this example) are arranged in the center of the front surface of the housing 20. When sound is output from each speaker of the speaker array 101, a sound beam having strong directivity in a predetermined direction is formed. The speaker device 10 controls the direction of the sound beam by controlling the delay amount of the sound output from each speaker. Since each speaker of the speaker array 101 is small, it cannot output a low frequency sound (for example, 200 Hz or less). Therefore, the speaker 50 is installed to compensate for low-frequency sounds that cannot be output by the speaker array 101.
　スピーカ装置１０は、テレビ１００等の外部装置と接続され、外部装置から入力したオーディオ信号に基づく音をスピーカ５０から出力する。 The speaker device 10 is connected to an external device such as the television 100, and outputs a sound based on an audio signal input from the external device from the speaker 50.
　スピーカ装置１０は、図１（Ｂ）に示すように、スタンド１によって、テレビ前方の床やラック等の水平な設置面に設置される。スタンド１は、図１（Ｂ）に示すように水平な設置面に設置される場合には、スピーカ装置１０を支持しつつ、スピーカ５０の出力する音を水平方向に拡散させる。 As shown in FIG. 1B, the speaker device 10 is installed on a horizontal installation surface such as a floor or a rack in front of the television by the stand 1. When the stand 1 is installed on a horizontal installation surface as shown in FIG. 1B, the sound output from the speaker 50 is diffused in the horizontal direction while supporting the speaker device 10.
　また、スピーカ装置１０は、図１（Ｃ）に示すように、筐体背面が壁面に設置される場合もある。この場合、スタンド１は、スピーカ５０の出力する音を水平方向に拡散させつつ、下方向（スピーカ５０の放音方向）にも通過させる。 In addition, as shown in FIG. 1C, the speaker device 10 may have the rear surface of the housing installed on the wall surface. In this case, the stand 1 allows the sound output from the speaker 50 to pass in the downward direction (sound emission direction of the speaker 50) while diffusing the sound output in the horizontal direction.
　以下、スタンド１の具体的な構造について説明する。図２は、スタンド１およびスピーカ５０の斜視図である。図３（Ａ）は、スタンド１の平面図であり、図３（Ｂ）は、断面図（図３（Ａ）に示すＡ－Ａの断面図）である。 Hereinafter, the specific structure of the stand 1 will be described. FIG. 2 is a perspective view of the stand 1 and the speaker 50. 3A is a plan view of the stand 1, and FIG. 3B is a cross-sectional view (a cross-sectional view along AA shown in FIG. 3A).
　図２に示すように、スタンド１は、上部枠体１１、下部枠体１２、支柱１３、拡散板１４、およびスペーサ１５からなる。 As shown in FIG. 2, the stand 1 includes an upper frame body 11, a lower frame body 12, a support column 13, a diffusion plate 14, and a spacer 15.
　上部枠体１１は、上下方向に薄い板状の部材であり、平面視して中央部が開口した輪形状である。ただし、上部枠体１１のうち筐体の背面側は、直線状の部分となっている。この直線状の部分は、筐体背面と面一になっている。上部枠体１１の上面側のうち中央部の開口部分にスピーカ５０が配置される。スピーカ５０の放音方向は、下向きになっているため、スピーカ５０から出力された音が当該開口部分から下側に抜けるようになっている。 The upper frame 11 is a plate-like member that is thin in the vertical direction, and has a ring shape with an open central portion in plan view. However, the back side of the housing of the upper frame 11 is a linear portion. This linear portion is flush with the rear surface of the housing. The speaker 50 is disposed in the central opening of the upper frame 11. Since the sound output direction of the speaker 50 is downward, the sound output from the speaker 50 is allowed to escape downward from the opening.
　下部枠体１２は、上部枠体１１と同じく上下方向に薄い板状の部材である。下部枠体１２のうち筐体の背面側も、直線状の部分となっており、筐体背面と面一になっている。 The lower frame 12 is a plate-like member that is thin in the vertical direction like the upper frame 11. The back side of the housing of the lower frame 12 is also a straight portion and is flush with the back of the housing.
　上部枠体１１の下面、および下部枠体１２の上面は、複数（同図においては４つ）の支柱１３で接続されている。したがって、上部枠体１１と下部枠体１２との間は、所定距離ｈだけ離れ、スタンド１の側面が開口した状態となる。ただし、開口した側面は、スピーカ５０を保護しつつ音響的に阻害しないように、パンチングメタル等の保護部材で覆われることが好ましい。 The lower surface of the upper frame body 11 and the upper surface of the lower frame body 12 are connected by a plurality of (four in the same figure) support columns 13. Therefore, the upper frame 11 and the lower frame 12 are separated by a predetermined distance h, and the side surface of the stand 1 is open. However, it is preferable that the opened side surface is covered with a protective member such as a punching metal so as to protect the speaker 50 and not acoustically obstruct.
　そして、下部枠体１２の中央部には、拡散板１４が配置されている。拡散板１４は、スピーカの放音方向に対して傾斜した方向に主面（上下面）を有する複数の板状部材からなる。 Further, a diffusion plate 14 is disposed at the center of the lower frame 12. The diffusion plate 14 is composed of a plurality of plate-like members having a main surface (upper and lower surfaces) in a direction inclined with respect to the sound output direction of the speaker.
　図３（Ａ）および図３（Ｂ）を参照して拡散板１４について詳細に説明する。拡散板１４は、下部枠体１２の中心付近から互いに離間してに並べられた輪形状の板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄからなる。ただし、板状部材１４１Ａ、１４１Ｂ、１４１Ｃ及び１４１Ｄの各々の主面は、中心部分が開口していない円錐台の側面に沿うように形成されている。また、板状部材１４１Ｂ、１４１Ｃ、１４１Ｄの主面は、後述するように、スピーカ５０の放音方向に対する傾斜度合いが等しく、互いに離間して配置されている。ただし、主面の傾斜角は、複数の板状部材間で等しくなくても良い。また、板状部材１４１Ｃは、板状部材１４１Ｂの周囲（外側）に配置され、板状部材１４１Ｄは、板状部材１４１Ｃの周囲に配置されている。また、板状部材１４１Ｂ及び１４１Ｃは、それぞれの主面が互いに対向するように配置されている。板状部材１４１Ｃ及び１４１Ｄも、それぞれの主面が互いに対向するように配置されている。板状部材１４１Ｄの主面は、背面側の部分が欠けた形状を有している。 The diffusion plate 14 will be described in detail with reference to FIGS. 3 (A) and 3 (B). The diffusion plate 14 includes a ring-shaped plate member 141A, a plate member 141B, a plate member 141C, and a plate member 141D that are arranged apart from each other from the vicinity of the center of the lower frame 12. However, each main surface of the plate-shaped members 141A, 141B, 141C, and 141D is formed along the side surface of the truncated cone whose central portion is not open. In addition, the main surfaces of the plate- like members 141B, 141C, and 141D have an equal inclination with respect to the sound output direction of the speaker 50 and are spaced apart from each other, as will be described later. However, the inclination angle of the main surface may not be equal among the plurality of plate-like members. The plate-shaped member 141C is disposed around (outside) the plate-shaped member 141B, and the plate-shaped member 141D is disposed around the plate-shaped member 141C. Further, the plate- like members 141B and 141C are arranged so that their main surfaces face each other. The plate- like members 141C and 141D are also arranged so that their main surfaces face each other. The main surface of the plate-shaped member 141D has a shape in which a portion on the back surface side is missing.
　これら板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、および板状部材１４１Ｄは、それぞれの主面がスピーカ５０の放音方向に対して外周方向に角度θ（θ＜９０°）だけ傾斜して並べられている。また、板状部材１４１Ｄの外側には、下部枠体１２の一部である傾斜部分１２１Ｅが、スピーカ５０の放音方向に対して角度θだけ傾斜して配置されている。スタンド１が筐体１５の下側であって、水平な設置面に設置された状態においては、板状部材１４１Ｂ、１４１Ｃ及び１４１Ｄの各々の上端部の高さが等しくなり、板状部材１４１Ｂ、１４１Ｃ及び１４１Ｄの各々の下端部の高さが等しくなるように、拡散部１４１は構成されている。 Each of the plate-like member 141A, the plate-like member 141B, the plate-like member 141C, and the plate-like member 141D is inclined at an angle θ (θ <90 °) in the outer circumferential direction with respect to the sound output direction of the speaker 50. Are lined up. In addition, an inclined portion 121 </ b> E that is a part of the lower frame body 12 is disposed outside the plate-shaped member 141 </ b> D so as to be inclined by an angle θ with respect to the sound output direction of the speaker 50. In the state where the stand 1 is located on the lower side of the casing 15 and installed on the horizontal installation surface, the heights of the upper ends of the plate- like members 141B, 141C, and 141D are equal, and the plate-like member 141B, The diffusion unit 141 is configured so that the lower ends of the 141C and 141D are equal in height.
　板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅは、それぞれ複数のフレーム１４２によって接続されている。なお、拡散板１４の各種構成（板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、およびフレーム１４２）と、下部枠体とは、樹脂により一体成型されているが、それぞれの部材を別体としてもよい。 The plate-shaped member 141A, the plate-shaped member 141B, the plate-shaped member 141C, the plate-shaped member 141D, and the inclined portion 121E are connected by a plurality of frames 142, respectively. The various configurations of the diffusion plate 14 (plate member 141A, plate member 141B, plate member 141C, plate member 141D, and frame 142) and the lower frame are integrally formed of resin. Each member may be separated.
　これにより、板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅは、それぞれ所定距離ｄだけ離れて並べられ、複数のスリットを形成することになる。 Thereby, the plate-like member 141A, the plate-like member 141B, the plate-like member 141C, the plate-like member 141D, and the inclined portion 121E are arranged apart from each other by a predetermined distance d to form a plurality of slits.
　また、図２に示したように、下部枠体１２の下面には、複数（同図においては３つ）のスペーサ１５が配置されている。スペーサ１５は、上下方向に薄い形状のゴム部材であり、下部枠体１２の下面に接着剤等で貼り付けられる。 Further, as shown in FIG. 2, a plurality (three in the figure) of spacers 15 are arranged on the lower surface of the lower frame 12. The spacer 15 is a rubber member that is thin in the vertical direction, and is attached to the lower surface of the lower frame 12 with an adhesive or the like.
　このスペーサ１５により、スタンド１が水平な設置面に設置された場合に、下部枠体１２と設置面との間に空間が形成される。なお、スペーサ１５は、必須ではなく、例えば下部枠体１２または拡散板１４の下面に突起を設けることで設置面との間に空間を形成することも可能である。 The spacer 15 forms a space between the lower frame 12 and the installation surface when the stand 1 is installed on a horizontal installation surface. The spacer 15 is not essential, and for example, a space may be formed between the spacer 15 and the installation surface by providing a protrusion on the lower surface of the lower frame 12 or the diffusion plate 14.
　したがって、スピーカ５０から出力された音は、板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅのそれぞれの間を抜けて、下部枠体１２と設置面との間に形成された空間から周囲に拡散することになる。また、スピーカ５０から出力された音は、上部枠体１１と下部枠体１２との間における側面（スタンド１の開口側面）からも周囲に拡散する。 Therefore, the sound output from the speaker 50 passes between each of the plate-like member 141A, the plate-like member 141B, the plate-like member 141C, the plate-like member 141D, and the inclined portion 121E, and the lower frame 12 and the installation surface. It diffuses to the surroundings from the space formed between. Further, the sound output from the speaker 50 is diffused from the side surface (opening side surface of the stand 1) between the upper frame body 11 and the lower frame body 12.
　また、図１（Ｃ）のように筐体背面が壁面に設置される場合も、スピーカ５０から出力された音は、板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅのそれぞれの間を抜けて、下方向に拡散することになる。この場合も、スピーカ５０から出力された音は、上部枠体１１と下部枠体１２との間における側面（スタンド１の開口側面）からも周囲に拡散する。 In addition, when the rear surface of the housing is installed on the wall as shown in FIG. 1C, the sound output from the speaker 50 is generated by the plate-like member 141A, the plate-like member 141B, the plate-like member 141C, and the plate-like member 141D. , And the slant portion 121E, and diffuses downward. Also in this case, the sound output from the speaker 50 is diffused from the side surface (opening side surface of the stand 1) between the upper frame body 11 and the lower frame body 12 to the surroundings.
　このように、スタンド１は、スピーカ装置１０を壁面に設置した場合も水平な設置面に設置した場合も、スピーカから出力された音を周囲に拡散させることができる。また、スピーカから出力された音が、板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅの間を抜けるため、拡散板１４がスピーカからの音圧を全て受けることがなく、拡散板１４自体が振動して余分な音が発生することがない。 Thus, the stand 1 can diffuse the sound output from the speaker to the surroundings regardless of whether the speaker device 10 is installed on a wall surface or a horizontal installation surface. In addition, since the sound output from the speaker passes between the plate-like member 141A, the plate-like member 141B, the plate-like member 141C, the plate-like member 141D, and the inclined portion 121E, the diffusion plate 14 reduces the sound pressure from the speaker. The diffuser plate 14 itself does not vibrate and no extra sound is generated.
　また、板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅは、それぞれ主面がスピーカ５０の放音方向に対して外周方向に角度θだけ傾斜して放射状に並べられているため、スタンド１の側面から設置面が見えないようになっている。これにより、例えばスピーカ装置１０およびスタンド１の色と設置面の色が異なる場合であっても、スタンド１から設置面が透けて見えないようになるため、外観上の美観を損ねることがない。 The plate-like member 141A, the plate-like member 141B, the plate-like member 141C, the plate-like member 141D, and the inclined portion 121E are inclined at an angle θ in the outer circumferential direction with respect to the sound output direction of the speaker 50, respectively. Since they are arranged radially, the installation surface cannot be seen from the side surface of the stand 1. Thereby, for example, even when the color of the speaker device 10 and the stand 1 is different from the color of the installation surface, the installation surface cannot be seen through from the stand 1, so that the appearance is not impaired.
　また、本実施形態では、以下の様な変形例も可能である。
　図４（Ａ）は、変形例１に係るスタンド１Ａの平面図である。図３と共通する構成については同一の符号を付し、説明を省略する。スタンド１Ａは、図３に示したスタンド１に対して、上部枠体１１および下部枠体１２のうち側面が、切り取られた直線状の部分となっている。したがって、図３のスタンド１に対して、左右方向に短い形状とすることができる。このスタンド１Ａも、スピーカ５０から出力された音を周囲に拡散させることができる。このように、スタンドの形状と拡散板の形状が異なっていてもよい。 In the present embodiment, the following modifications are possible.
FIG. 4A is a plan view of a stand 1A according to the first modification. Components that are the same as those in FIG. 3 are given the same reference numerals, and descriptions thereof are omitted. The stand 1 </ b> A is a linear portion with the side surfaces of the upper frame body 11 and the lower frame body 12 cut off from the stand 1 shown in FIG. 3. Therefore, it can be made short in the left-right direction with respect to the stand 1 of FIG. The stand 1A can also diffuse the sound output from the speaker 50 to the surroundings. Thus, the shape of the stand and the shape of the diffusion plate may be different.
　図４（Ｂ）は、変形例２に係るスタンド１Ｂの平面図である。図３と共通する構成については同一の符号を付し、説明を省略する。スタンド１Ｂは、図３に示したスタンド１に対して、上部枠体１１、下部枠体１２、板状部材１４１Ａ、板状部材１４１Ｂ、板状部材１４１Ｃ、板状部材１４１Ｄ、および傾斜部分１２１Ｅが、楕円形状（ただし、上部枠体１１および下部枠体１２の筐体の背面側は、直線状の部分となっている。）となっている。したがって、図３のスタンド１に対して、正面方向（スピーカ装置の奥行き方向）に短い形状とすることができる。このスタンド１Ｂも、スピーカ５０から出力された音を周囲に拡散させることができる。 FIG. 4B is a plan view of a stand 1B according to the second modification. Components that are the same as those in FIG. 3 are given the same reference numerals, and descriptions thereof are omitted. The stand 1B has an upper frame 11, a lower frame 12, a plate member 141A, a plate member 141B, a plate member 141C, a plate member 141D, and an inclined portion 121E compared to the stand 1 shown in FIG. The oval shape (however, the back side of the casing of the upper frame body 11 and the lower frame body 12 is a linear portion). Therefore, it can be made short in the front direction (depth direction of the speaker device) with respect to the stand 1 of FIG. This stand 1B can also diffuse the sound output from the speaker 50 to the surroundings.
　また、図５（Ａ）の変形例３に示すように、平面視して長方形状の板状部材を配置するスタンド１Ｃのような態様も可能であるし、図５（Ｂ）の変形例４に示すように、平面視して多角形状（この例では５角形状）の板状部材を放射状に配置するスタンド１Ｄのような態様も可能である。 Moreover, as shown in the modification 3 of FIG. 5A, an aspect like the stand 1C which arrange | positions a rectangular plate-shaped member by planar view is also possible, and the modification 4 of FIG. 5B is possible. As shown in Fig. 5, a mode like a stand 1D in which plate-shaped members having a polygonal shape (in this example, a pentagonal shape) are arranged radially when viewed in plan is also possible.
