Description

本発明は、外郭をなす外枠に開閉自在に組付けた中枠にスピーカユニットを設けた遊技機に関するものである。 The present invention relates to a gaming machine in which a speaker unit is provided on an inner frame that is assembled to an outer frame that forms an outer shell so as to be freely opened and closed.

例えば遊技機の代表例の一つであるパチンコ機には、所要位置にスピーカユニットが配設されており、遊技状態に応じて多様な音をスピーカユニットから発することにより、遊技の臨場感や興趣を高めるよう構成されている。ここで、遊技の臨場感や興趣を高めるには、スピーカユニットから低音域の音を、大音量で出力し得ることが望まれる。ところで、スピーカユニットから発せられる音の音域と音量は、スピーカユニットの口径に依存することが知られており、低音域の音を、大音量で出力するためには、大きなスピーカユニットを用いる必要がある。しかしながら、近年は、遊技盤の大型化が進み、各種部材を配設可能なスペースが限定されているのが現状であり、スピーカユニットとしてはできる限り小型のものを少数用いる構成とすることが求められている。このため、高性能なスピーカユニットを用いたとしても、その特性上、低音域の音を大音量で出力することは困難で、遊技の迫力不足を招来する難点が指摘される。そこで、バスレフ型やバックロードホーン型のスピーカユニットを設け、スピーカユニットから出力される低音域を増強して遊技の臨場感や興趣を向上するようにしたパチンコ機が提案されている(例えば、特許文献１〜３参照)。 For example, a pachinko machine, which is one of the representative examples of gaming machines, is provided with a speaker unit at a required position, and various sounds are emitted from the speaker unit according to the gaming state, so that the realism and interest of gaming can be improved. Is configured to enhance. Here, in order to enhance the realism and interest of the game, it is desired that low-frequency sounds can be output from the speaker unit at a high volume. By the way, it is known that the range and volume of the sound emitted from the speaker unit depend on the diameter of the speaker unit, and in order to output the low range sound at a high volume, it is necessary to use a large speaker unit. is there. However, in recent years, the size of game boards has been increasing, and the space in which various members can be placed is currently limited, and it is desired to use a small number of speaker units that are as small as possible. It has been. For this reason, even if a high-performance speaker unit is used, it is difficult to output a low-frequency sound at a large volume due to its characteristics, and it is pointed out that the game is not powerful enough. Therefore, a pachinko machine has been proposed in which a bass reflex type or back load horn type loudspeaker unit is provided and the low frequency range output from the loudspeaker unit is enhanced to improve the realism and interest of the game (for example, patents) References 1-3).

例えば、一般的なパチンコ機は、外郭をなす外枠に開閉自在に組付けられた中枠に遊技盤を配設し、該中枠に対して開閉自在に組付けられた前枠に遊技盤を透視保護するガラス板が配設される。そして、特許文献１に記載されたパチンコ機では、前記中枠にスピーカユニットおよびバックロードホーンを形成するよう構成されている。また、前記特許文献２には、前記前枠にスピーカユニットおよびバックロードホーンを形成する構成が開示されている。そして、特許文献３に開示されたパチンコ機では、外枠の外形形状に略合致する形状に中枠が形成され、該中枠に設けた下球皿の下方位置にスピーカユニットおよびバックロードホーンを形成するようになっている。このように、前記特許文献１〜３には、パチンコ機の中枠あるいは前枠にスピーカユニットおよびバックロードホーンを設けて、スピーカユニットから後方へ出力された「音」を増強するようになっている。
特開２００２−１７２２１７号公報特開２００３−９３６１２号公報特開２００３−１３５６８１号公報 For example, in a general pachinko machine, a game board is arranged on an inner frame that is assembled to be opened and closed to an outer frame that forms an outer shell, and a game board is installed on a front frame that is assembled to be opened and closed with respect to the inner frame A glass plate for protecting the see-through is disposed. The pachinko machine described in Patent Document 1 is configured to form a speaker unit and a back load horn on the inner frame. In addition, Patent Document 2 discloses a configuration in which a speaker unit and a back load horn are formed on the front frame. In the pachinko machine disclosed in Patent Document 3, the inner frame is formed in a shape that substantially matches the outer shape of the outer frame, and the speaker unit and the backload horn are placed below the lower ball tray provided on the inner frame. It comes to form. As described above, in Patent Documents 1 to 3, the speaker unit and the back load horn are provided in the middle frame or the front frame of the pachinko machine to enhance the “sound” output rearward from the speaker unit. Yes.

ところで、前記中枠の裏側には、パチンコ球が通過するオーバーフロー球用通路、ファール球用通路、アウト球用通路等の多くの通路が形成されると共に、各種制御装置や遊技機構成部品が多数配設されており、また同様に、前記前枠には遊技盤を透視保護するガラス板が組付けられることから、これら中枠や前枠にはスペース的な余裕はほとんどない。このため、これら中枠および前枠においてスピーカユニットやバックロードホーンを設ける部位は非常に限定されることから、スピーカユニットの更なる小型化や、バックロードホーンが短くなる難点を内在しており、スピーカユニットから出力される低音域を増強して充分に遊技の臨場感や興趣を向上しているとは云えないのが現状であった。
そこで、本発明は、スピーカユニットから充分に迫力のある低音域の音を出力させ、迫力や臨場感に優れた興趣ある遊技を行ない得る遊技機を提供することを目的とする。 By the way, on the back side of the inner frame, there are many passages such as an overflow ball passage, a foul ball passage, and an out ball passage through which pachinko balls pass, and there are many various control devices and game machine components. Similarly, since the front frame is assembled with a glass plate for see-through protection of the game board, there is almost no space in the middle frame and the front frame. For this reason, the parts where the speaker unit and the back load horn are provided in the middle frame and the front frame are very limited.Therefore, further downsizing of the speaker unit and the difficulty of shortening the back load horn are inherent. At present, it cannot be said that the low frequency range output from the speaker unit has been enhanced to sufficiently improve the realism and interest of the game.
In view of the above, an object of the present invention is to provide a gaming machine capable of outputting a sufficiently powerful low-frequency sound from a speaker unit and performing an interesting game with excellent power and realism.

On the side, a plate portion 14 having a required height called a curtain plate or a waist plate is disposed to form a vertically long rectangular frame. Then, the middle frame 16 is formed in a size that matches the opening size defined by the upper frame member 12a, the right frame member 12c, the left frame member 12d, and the plate portion 14, and the middle frame 16 is closed. Sometimes, the back side of the pachinko machine 10 is not visible from the front side (see FIG. 1). In addition, a front frame 18 assembled with a glass plate 18a for see-through protection of the game board is provided on the front side of the middle frame 16 so as to be openable and closable, and a pachinko ball is stored at a position below the front frame 18. An upper ball tray 20 is provided.

前記中枠１６における上球皿２０の下方位置には、パチンコ機１０(外枠１２)の左右方向の幅寸法に略整合する大きさに形成されたセット板２２が設けられており、該セット板２２の左右方向の略中央位置に、上球皿２０に貯留しきれないパチンコ球を貯留する下球皿２４を形成してある。また、前記セット板２２における下球皿２４の右位置には、ハンドル部材２６が配設されており、該ハンドル部材２６の打出し操作により、前記上球皿２０に貯留したパチンコ球が遊技盤の盤面に向けて打出されて所要の遊技が行なわれるようになっている。更に、前記中枠１６の裏側には、前記セット板２２の左位置(ヒンジ手段４４側)に、遊技内容に合わせて効果音や音声を出力するスピーカユニット２８が配置されて、遊技内容に合わせてスピーカユニット２８から各種効果音や音声を発することで、遊技の興趣を高めるように構成されている。ここで、前記スピーカユニット２８は、前記中枠１６の裏側におけるスピーカユニット２８(後述する収容箱体３０)の上方位置に配設された音声制御装置４２(図４参照)に接続されており、該音声制御装置４２の制御に基づいてスピーカユニット２８から各種の音を出力するようになっている。 At the lower position of the upper ball tray 20 in the middle frame 16 is provided a set plate 22 formed in a size that substantially matches the width dimension in the left-right direction of the pachinko machine 10 (outer frame 12). A lower ball tray 24 that stores pachinko balls that cannot be stored in the upper ball tray 20 is formed at a substantially central position in the left-right direction of the plate 22. Further, a handle member 26 is disposed at the right position of the lower ball tray 24 in the set plate 22, and the pachinko balls stored in the upper ball tray 20 are played by the launch operation of the handle member 26. The game is designed to be played on the board. Further, on the back side of the middle frame 16, a speaker unit 28 that outputs sound effects and sounds in accordance with the game content is arranged at the left position (on the hinge means 44 side) of the set plate 22 so as to match the game content. The speaker unit 28 emits various sound effects and sounds, thereby enhancing the interest of the game.

Thus, only the front side is exposed forward (player side). That is, the inner frame 16 and the set plate 22 function as a so-called baffle plate that isolates the front and rear of the speaker unit 28, and only the sound output from the front side of the speaker unit 28 is the first opening 16a (first The first cover member 38) is transmitted to the front (player side), and the first cover member 38 is configured not to directly touch the speaker unit 28 from the front side.

また、前記中枠１６における左位置(ヒンジ手段４４側)の裏側には、図４に示すように、前記スピーカユニット２８の背面側に所要の空間(以下空気室３０ａという)を画成した状態で、該スピーカユニット２８の背面側を覆う収容箱体(収容部)３０を取付けてある。なお、前記収容箱体３０は、ゴムパッキン等のシール材を介して前記中枠１６の裏側に密着するよう取付けられており、前記スピーカユニット２８の背面側を略完全に隔離している。すなわち、前記スピーカユニット２８の前面側に出力された音波と、背面側に出力された音波とが、相互に干渉するのを防止している。また、前記収容箱体３０を画成する後壁部３１の下部位置には、前記空気室３０ａに開口する第１接続口３２が中枠１６の閉成時に後方に開口するよう開設されており(図４または図５(a),(b)参照)、前記スピーカユニット２８を作動した際に、スピーカユニット２８の背面側から空気室３０ａ内に出力された音波が、該第１接続口３２を介して収容箱体３０の後方に伝播するようになっている。なお、実施例では、スピーカユニット２８として中音再生用のコーン形スピーカユニット２８を採用している。また、実施例では、前記後壁部３１が、後述する突出部(第２当接部)３５に当接する第１当接部として機能するようになっている。 Further, as shown in FIG. 4, a required space (hereinafter referred to as an air chamber 30a) is defined on the back side of the speaker unit 28 on the back side of the left position (on the hinge means 44 side) of the middle frame 16. A housing box (housing portion) 30 that covers the back side of the speaker unit 28 is attached. The storage box 30 is attached so as to be in close contact with the back side of the middle frame 16 through a sealing material such as rubber packing, and the back side of the speaker unit 28 is substantially completely isolated. That is, the sound wave output to the front side of the speaker unit 28 and the sound wave output to the back side are prevented from interfering with each other. A first connection port 32 that opens to the air chamber 30a is opened at the lower position of the rear wall 31 that defines the storage box 30 so as to open rearward when the middle frame 16 is closed. (Refer to FIG. 4 or FIG. 5 (a), (b)), when the speaker unit 28 is operated, the sound wave output from the back side of the speaker unit 28 into the air chamber 30a is the first connection port 32. It propagates to the rear of the storage box 30 via the. In the embodiment, the cone type speaker unit 28 for medium sound reproduction is adopted as the speaker unit 28. In the embodiment, the rear wall portion 31 functions as a first abutting portion that abuts on a protruding portion (second abutting portion) 35 described later.

また、図３または図４に示すように、前記板部１４の裏側には、該板部１４の略全幅に亘って延在する通路形成部材３３が配設されており、該通路形成部材３３と板部１４とによりダクト部３４が形成されている。なお、前記通路形成部材３３は、ゴムパッキン等のシール材(図示せず)を介して前記板部１４の裏側に密着状態で取付けられている。ここで、前記通路形成部材３３は、前記板部１４の左端部近傍で、該板部１４より上方に突出する突出部３５が形成されており、該突出部３５に、前方に開口する第２接続口３６が開設されている(図５(a)参照)。なお、前記第２接続口３６は、前記中枠１６の閉成時に前記収容箱体３０の第１接続口３２と前後に整列する位置に、該第１接続口３２と整合する大きさで開設されている。また、前記突出部３５は、前記第２接続口３６と整合する開口形状に形成された環状のゴムパッキン等の弾性材からなるシール材３７(図３または図５(a),(b)参照)を備えており、前記中枠１６の閉成時に、該シール材３７が前記収容箱体３０の前記後壁部３１に当接した状態で、第１接続口３２と第２接続口３６とが連通するようになっている。 Further, as shown in FIG. 3 or FIG. 4, a passage forming member 33 extending over substantially the entire width of the plate portion 14 is disposed on the back side of the plate portion 14. A duct portion 34 is formed by the plate portion 14. The passage forming member 33 is attached in close contact with the back side of the plate portion 14 via a sealing material (not shown) such as rubber packing. Here, the passage forming member 33 is formed with a protruding portion 35 protruding upward from the plate portion 14 in the vicinity of the left end portion of the plate portion 14, and a second opening opening forward in the protruding portion 35. A connection port 36 is established (see FIG. 5A). The second connection port 36 is opened at a position aligned with the first connection port 32 of the storage box 30 in the front-rear direction when the middle frame 16 is closed and with a size that matches the first connection port 32. Has been. Further, the protruding portion 35 is a sealing material 37 (see FIG. 3 or FIGS. 5A and 5B) made of an elastic material such as an annular rubber packing formed in an opening shape that matches the second connection port 36. ), And when the middle frame 16 is closed, the sealing member 37 is in contact with the rear wall portion 31 of the housing box 30, and the first connection port 32, the second connection port 36, Has come to communicate.

ここで、前記突出部３５のシール材３７は、前記中枠１６の閉成時に前記収容箱体３０の後壁部３１が臨む基準位置より前方に突出するよう形成されており(図５(a),(b)参照)、該中枠１６を外枠１２に対して閉成した際に、該後壁部３１が突出部３５(シール材３７)に当接する。この状態で、更に前記中枠１６を完全に閉成すると、前記後壁部３１が突出部３５(シール材３７)に圧接(密着)してシール材３７が弾性変形し、これにより第１接続口３２および第２接続口３６が密閉状態で連通接続するようになっている。すなわち、前記中枠１６を閉成することで、収容箱体３０およびダクト部３４(板部１４および通路形成部材３３)がスピーカユニット２８のエンクロージャ構造をなすようになっている。このため、前記スピーカユニット２８の背面側から収容箱体３０の空気室３０ａ内に出力された音波は、前記第１接続口３２および第２接続口３６を介してダクト部３４内に伝播する。 Here, the sealing material 37 of the protruding portion 35 is formed so as to protrude forward from a reference position where the rear wall portion 31 of the housing box 30 faces when the middle frame 16 is closed (FIG. ), (b)), when the inner frame 16 is closed with respect to the outer frame 12, the rear wall portion 31 comes into contact with the protruding portion 35 (seal member 37). In this state, when the inner frame 16 is further completely closed, the rear wall portion 31 is pressed (contacted) to the projecting portion 35 (seal member 37), and the seal member 37 is elastically deformed, whereby the first connection is made. The port 32 and the second connection port 36 communicate with each other in a sealed state. That is, by closing the middle frame 16, the housing box 30 and the duct portion 34 (the plate portion 14 and the passage forming member 33) form an enclosure structure of the speaker unit 28. For this reason, the sound wave output from the back side of the speaker unit 28 into the air chamber 30 a of the housing box 30 propagates into the duct portion 34 via the first connection port 32 and the second connection port 36.

また、前記板部１４の右端部近傍には、前後に貫通する第２の開口部１４ａが開設されており、前記ダクト部３４が前記突出部３５の第２接続口３６、および第２の開口部１４ａに連通するよう構成される。すなわち、前記第１および第２接続口３２,３６を介して前記収容箱体３０の空気室３０ａから前記ダクト部３４内に伝播した音波は、前記第２の開口部１４ａを介してパチンコ機１０の前方(遊技者側)へ出力されるようになっている。 Further, a second opening 14a penetrating in the front-rear direction is formed in the vicinity of the right end portion of the plate portion 14, and the duct portion 34 is connected to the second connection port 36 of the protruding portion 35 and the second opening. It is comprised so that it may communicate with the part 14a. That is, sound waves propagated from the air chamber 30a of the housing box 30 through the first and second connection ports 32 and 36 into the duct portion 34 are transmitted to the pachinko machine 10 via the second opening 14a. Is output to the front (player side).

前記ダクト部３４は、図２〜図４に示すように、前記第２の開口部１４ａに連通するメインダクト部３４ａと、該メインダクト部３４ａの上流端および前記第２接続口３６の夫々に連通するサブダクト部３４ｂとから構成される。前記メインダクト部３４ａは、前記板部１４の裏側における左右方向の略全幅に亘って延在すると共に、左方から右方へ向けて延在方向に交差する方向(上下方向)の幅員(すなわちメインダクト部３４ａの所要位置における開口面積が漸増)が漸増するホーン状に形成されている。また、前記サブダクト部３４ｂは、基本的には左右方向に折返す蛇行状に形成されて、該板部１４の左端部近傍で、前記メインダクト部３４ａの上流側に連通接続するようになっている。前記サブダクト部３４ｂの具体的な形状について説明すると、図２に示すように、前記第２接続口３６に接続するよう所定長さ下方に延在すると共に、前記板部１４の上端縁に沿って右方向に所定長さ延在する。その後左方向に折返して前記メインダクト部３４ａに沿うよう所定長さ延在した後に、更に板部１４の左上角方向へ向けて延在するよう折れ曲がり、板部１４の左端部近傍において下方へ向けて延在するよう折れ曲がってメインダクト部３４ａの上流側に接続するようになっている。なお、前記サブダクト部３４ｂに関しても、前記第２接続口３６から離間するにつれて、延在方向に交差する方向の幅員が漸増(すなわちサブダクト部３４ｂの所要位置における開口面積が漸増)するよう形成されており、ダクト部３４の全体が蛇行したホーン状になっている。 As shown in FIGS. 2 to 4, the duct portion 34 is connected to the main duct portion 34 a communicating with the second opening portion 14 a, the upstream end of the main duct portion 34 a, and the second connection port 36. It is comprised from the subduct part 34b which connects. The main duct portion 34a extends over substantially the entire width in the left-right direction on the back side of the plate portion 14, and has a width in the direction (vertical direction) intersecting the extending direction from left to right (that is, the vertical direction). The main duct portion 34a is formed in a horn shape in which the opening area at a required position is gradually increased. The sub duct portion 34b is basically formed in a meandering shape that is folded back in the left-right direction, and is connected to the upstream side of the main duct portion 34a in the vicinity of the left end portion of the plate portion 14. Yes. The specific shape of the sub duct portion 34b will be described. As shown in FIG. 2, the sub duct portion 34b extends downward by a predetermined length so as to be connected to the second connection port 36, and extends along the upper edge of the plate portion 14. It extends a predetermined length in the right direction. Thereafter, it is folded back to the left and extends for a predetermined length along the main duct portion 34a, and is further bent so as to extend in the upper left corner direction of the plate portion 14, and is directed downward in the vicinity of the left end portion of the plate portion 14. It is bent so as to extend and is connected to the upstream side of the main duct portion 34a. Incidentally, with respect to the sub-duct portion 34b, as spaced from the second connection port 36, is formed so that (opening area gradually increases in the required position i.e. the sub duct portion 34b) to the direction of width intersecting the extending direction gradually increases The entire duct portion 34 has a meandering horn shape.

すなわち、前記第１および第２接続口３２,３６を介して前記収容箱体３０の空気室３０ａから前記ダクト部３４内に伝播した音波は、前記第２の開口部１４ａを介してパチンコ機１０の前方(遊技者側)へ出力されるよう構成してある。換言すると、前記ダクト部３４は、スピーカユニット２８のエンクロージャ構造における所謂バックロードホーンとして機能し、スピーカユニット２８の背面側から前記空気室３０ａに出力された音波がダクト部３４を通過することで、その低音域を増強して第２の開口部１４ａから出力されるよう構成してある。なお、前記板部１４には、前記第２の開口部１４ａと対応する位置にメッシュ状の第２カバー部材(カバー部材)４０を取付けてあり、パチンコ機１０の前側からダクト部３４内への手指や異物の挿入を防止している。 That is, sound waves propagated from the air chamber 30a of the housing box 30 through the first and second connection ports 32 and 36 into the duct portion 34 are transmitted to the pachinko machine 10 via the second opening 14a. Is output to the front (player side). In other words, the duct portion 34 functions as a so-called back load horn in the enclosure structure of the speaker unit 28, and sound waves output from the back side of the speaker unit 28 to the air chamber 30a pass through the duct portion 34. The bass range is enhanced and output from the second opening 14a. In addition, a mesh-like second cover member (cover member) 40 is attached to the plate portion 14 at a position corresponding to the second opening portion 14a, and the front portion of the pachinko machine 10 enters the duct portion 34. The insertion of fingers and foreign objects is prevented.

〔実施例の作用〕
次に、実施例に係る遊技機の作用につき説明する。遊技者が前記ハンドル部材２６を操作してパチンコ球を遊技盤面に打出して所要の遊技が開始されると、前記音声制御装置４２の制御に基づいて前記スピーカユニット２８から効果音や音声等が発せられる。ところで、一般的にスピーカユニット２８から音が出力されるときには、振動板を境界としてスピーカユニット２８の前後において逆の作用が行なわれる。具体的には、例えば振動板が前方に動くときには、スピーカユニット２８の前面側では空気が押されて「密」となる一方で、背面側は空気の薄い「疎」となり、振動板が後方に動くときには、スピーカユニット２８の背面側では空気が押されて「密」となる一方で、前面側は空気の薄い「疎」となる。すなわち、スピーカユニット２８の前後には、逆位相の関係となる音波が出力されることとなる。この場合に、前記スピーカユニット２８の前面側から出力された音波と、背面側から出力された逆位相の音波とが干渉すると、互いに打消しあって遊技者に伝わる音が不鮮明になることが知られている。殊に、波長の長い低音域の音に対する影響が顕著で、迫力や臨場感の低下を招来する要因となる。 (Effects of Example)
Next, the operation of the gaming machine according to the embodiment will be described. When a player operates the handle member 26 to strike a pachinko ball on the surface of the game board and a required game is started, sound effects, sounds, etc. are output from the speaker unit 28 based on the control of the sound control device 42. Be emitted. By the way, generally, when sound is output from the speaker unit 28, the reverse action is performed before and after the speaker unit 28 with the diaphragm as a boundary. Specifically, for example, when the diaphragm moves forward, air is pushed and becomes “dense” on the front side of the speaker unit 28, while the back side becomes thin “sparse” and the diaphragm is moved backward. When moving, air is pushed and becomes “dense” on the back side of the speaker unit 28, while the air is thin and “sparse” on the front side. That is, sound waves having an opposite phase relationship are output before and after the speaker unit 28. In this case, it is known that if the sound wave output from the front side of the speaker unit 28 and the opposite phase sound wave output from the back side interfere with each other, the sound transmitted to the player becomes unclear. It has been. In particular, the influence on the low-frequency sound having a long wavelength is remarkable, which causes a decrease in force and realism.

この実施例では、スピーカユニット２８の前面側と背面側とを、バッフル板として機能する中枠１６(セット板２２)により仕切ると共に、該スピーカユニット２８の背面側を覆う収容箱体３０を、シール材３７を介して中枠１６の裏側に密着するよう構成してあるから、該スピーカユニット２８の前面側と背面側とを確実に隔離し得る。このため、スピーカユニット２８の前面側から出力される音波と、背面側から出力される音波との干渉を効果的に抑制できるから、音が不鮮明になるのは防止され、鮮明な音により遊技演出を行なうことができる。 In this embodiment, the front side and the rear side of the speaker unit 28 are partitioned by the middle frame 16 (set plate 22) functioning as a baffle plate, and the housing box 30 covering the back side of the speaker unit 28 is sealed. Since it is configured to be in close contact with the back side of the middle frame 16 via the material 37, the front side and the back side of the speaker unit 28 can be reliably separated. For this reason, since the interference between the sound wave output from the front side of the speaker unit 28 and the sound wave output from the back side can be effectively suppressed, the sound is prevented from becoming unclear and the game effect is produced by the clear sound. Can be performed.

また、実施例では、前記外枠１２の板部１４より上方に突出させた突出部３５に、前方へ向けて開口する第２接続口３６を開設すると共に、当該突出部３５に設けたシール材３７が、前記中枠１６の閉成時に収容箱体３０の後壁部３１が臨む基準位置より前方に突出するよう形成してある。従って、前記中枠１６を閉成した際に前記収容箱体３０の後壁部３１が基準位置へ変位することで、該後壁部３１が突出部３５(シール材３７)に押付けられる(圧接する)。このとき、前記突出部３５のシール材３７が弾性変形することで、前記収容箱体３０の後壁部３１と突出部３５(シール材３７)とが密着し、これにより前記第１および第２接続口３２,３６が密閉状態で連通接続する。すなわち、前記収容箱体３０とダクト部３４との接続部位(第１および第２接続口３２,３６)の気密性が確保されるから、この接続部分からの音漏れを抑制することができ、板部１４の開口部１４ａから出力される音質の低下を防止し得る。 Further, in the embodiment, the second connecting port 36 that opens forward is opened in the protruding portion 35 that protrudes upward from the plate portion 14 of the outer frame 12, and the sealing material provided in the protruding portion 35. 37 is formed so as to protrude forward from the reference position where the rear wall 31 of the housing box 30 faces when the middle frame 16 is closed. Accordingly, when the middle frame 16 is closed, the rear wall portion 31 of the housing box 30 is displaced to the reference position, so that the rear wall portion 31 is pressed against the protruding portion 35 (seal member 37) (pressure contact). Do). At this time, the sealing material 37 of the protruding portion 35 is elastically deformed, whereby the rear wall portion 31 and the protruding portion 35 (sealing material 37) of the housing box 30 are brought into close contact with each other. The connection ports 32 and 36 are connected in a sealed state. That is, since the airtightness of the connection part (first and second connection ports 32 and 36) between the housing box 30 and the duct part 34 is ensured, sound leakage from the connection part can be suppressed, The deterioration of the sound quality output from the opening 14a of the plate part 14 can be prevented.

なお、前記中枠１６を外枠１２に対して開閉自在に組付ける関係上、該中枠１６を支持するヒンジ手段４４には所謂「遊び」が必要とされる。このため、前記中枠１６に設けた収容箱体３０の後壁部３１の第１接続口３２を、前記ヒンジ手段４４から離間する端部側(すなわち右端部側)に設けた場合には、該中枠１６の閉成時に第１接続口３２の移動距離が長くなることから、中枠１６のガタツキにより第１接続口３２と第２接続口３６とを整合させるのが困難となり、確実に整合しない場合には、その接続部分からの音漏れを招来する虞がある。また、前記施錠手段４６により前記中枠１６を閉成状態で保持した場合には、該施錠手段４６に必要とされる「遊び」により、中枠１６の左端部に較べて右端部側は前後に移動する。このため、前記中枠１６の右端部側に第１接続口３２を設けるよう構成した場合には、中枠１６を閉成した状態であっても、第１接続口３２と第２接続口３６とが離間する可能性がある。これに対して、実施例では、中枠１６の閉成時に移動距離の短いヒンジ手段４４側(すなわち左端部近傍)に第１接続口３２を設けると共に、該第１接続口３２と対応するよう第２接続口３６を外枠１２側に形成したから、該中枠１６の閉成時に両接続口３２,３６を正確に整合することができ、音漏れによる音質の低下を効果的に防止し得る。更には、前記第１接続口３２を中枠１６の左端部側に設けたことで、該中枠１６を閉成状態で保持した状態で第１接続口３２と第２接続口３６とを確実に密閉状態で連通させることが可能となる。 The hinge means 44 that supports the middle frame 16 requires so-called “play” because the middle frame 16 is assembled to the outer frame 12 so as to be openable and closable. For this reason, when the first connection port 32 of the rear wall portion 31 of the storage box 30 provided in the inner frame 16 is provided on the end portion side (that is, the right end portion side) separated from the hinge means 44, Since the movement distance of the first connection port 32 becomes long when the middle frame 16 is closed, it becomes difficult to align the first connection port 32 and the second connection port 36 due to the backlash of the middle frame 16, and reliably If they do not match, there is a risk of sound leakage from the connecting portion. Further, when the middle frame 16 is held in the closed state by the locking means 46, the right end portion side is longer than the left end portion of the middle frame 16 due to “play” required for the locking means 46. Move to. For this reason, when the first connection port 32 is provided on the right end side of the middle frame 16, the first connection port 32 and the second connection port 36 even when the middle frame 16 is closed. May be separated from each other. On the other hand, in the embodiment, the first connection port 32 is provided on the hinge means 44 side having a short moving distance when the middle frame 16 is closed (that is, in the vicinity of the left end portion), and corresponds to the first connection port 32. Since the second connection port 36 is formed on the outer frame 12 side, the connection ports 32 and 36 can be accurately aligned when the middle frame 16 is closed, and the deterioration of sound quality due to sound leakage is effectively prevented. obtain. Further, by providing the first connection port 32 on the left end side of the middle frame 16, the first connection port 32 and the second connection port 36 can be securely connected with the middle frame 16 held in a closed state. It is possible to communicate with each other in a sealed state.

また、実施例では中枠１６を閉成した状態(すなわち、遊技が行なわれる状態)では、前記第１接続口３２と第２接続口３６とが密閉状態で接続することにより、該収容箱体３０とダクト部３４によりエンクロージャ構造をなすと共に、該ダクト部３４として、音の入力側(すなわち第２接続口３６)から出力側(すなわち板部１４の第２の開口部１４ａ)へ向かうにつれて開口面積が漸増するホーン状の所謂バックロードホーンタイプを採用している。従って、スピーカユニット２８の背面側から収容箱体３０に出力された音は、ダクト部３４を通過することにより低音域が増強されて、前記第２の開口部１４ａから遊技者側に出力されるから、遊技の臨場感や興趣を向上する効果を期待し得る。なお、前記中枠１６と収容箱体３０との間、および前記板部１４とダクト部３４との間にシール材３７を設けて気密性を高めるよう構成してある。従って、スピーカユニット２８の背面側から出力された音波が、これら部材間１６,３０(１４,３４)からパチンコ機１０の前方に漏れるのを防止でき、スピーカユニット２８の前後に出力された音波の干渉による音質の低下を阻止して、前記第２の開口部１４ａからクリアな音を出力できる。 In the embodiment, when the middle frame 16 is closed (that is, a state where a game is performed), the first connection port 32 and the second connection port 36 are connected in a sealed state, whereby the housing box 30 and the duct portion 34, and the duct portion 34 is opened from the sound input side (ie, the second connection port 36) toward the output side (ie, the second opening portion 14a of the plate portion 14). A so-called back load horn type having a gradually increasing area is employed. Therefore, the sound output from the back side of the speaker unit 28 to the housing box 30 is output to the player side from the second opening 14a by passing through the duct portion 34 to enhance the bass range. Therefore, it can be expected to improve the realism and interest of the game. A sealing material 37 is provided between the inner frame 16 and the storage box 30 and between the plate portion 14 and the duct portion 34 so as to improve the airtightness. Therefore, it is possible to prevent sound waves output from the back side of the speaker unit 28 from leaking to the front of the pachinko machine 10 from between these members 16, 30 (14, 34), and the sound waves output before and after the speaker unit 28. It is possible to prevent a decrease in sound quality due to interference and output a clear sound from the second opening 14a.

ここで、バックロードホーンタイプのエンクロージャでは、充分な性能(すなわち低音域の増強効果)を発揮するには、前記ダクト部３４の全長をできる限り長くすることが求められる。実施例では、スピーカユニット２８を中枠１６に配設すると共に、スペース的に余裕のある外枠１２(板部１４の裏側)にバックロードホーンとしてのダクト部３４を設けたことで、該板部１４の略全幅を利用してダクト部３４の全長を長くすることができる。このため、ダクト部３４を他の部位(中枠１６や前枠１８等)に設けた場合に較べて、スピーカユニット２８から出力される低音域を効果的に増強して迫力や臨場感に優れると共に、所謂歯切れのよい高音質(高品質)な音を出力することができ、より一層興趣ある遊技演出を行ない得る利点がある。殊に、実施例のように、前記板部１４の右端部近傍に前記第２の開口部１４ａを設けると共に、該板部１４の左端部近傍に前記収容箱体３０(空気室３０ａ)に接続する第２接続口３６を設けることで、板部１４の略全幅を最大限利用してダクト部３４を形成することが可能となるから、該ダクト部３４の全長を最大限長くすることができ、低音域の増強をより効果的に図り得る利点がある。 Here, in the back load horn type enclosure, in order to exhibit sufficient performance (that is, the enhancement effect of the low frequency range), it is required to make the entire length of the duct portion 34 as long as possible. In the embodiment, the speaker unit 28 is disposed on the inner frame 16 and the duct portion 34 as a backload horn is provided on the outer frame 12 (the back side of the plate portion 14) having a sufficient space, so that the plate The overall length of the duct portion 34 can be increased by utilizing the substantially entire width of the portion 14. For this reason, compared with the case where the duct part 34 is provided in other parts (the middle frame 16, the front frame 18, etc.), the low frequency range output from the speaker unit 28 is effectively enhanced and excellent in power and presence. At the same time, there is an advantage that a so-called crisp high-quality sound (high quality) can be output, and a more interesting game effect can be performed. In particular, as in the embodiment, the second opening portion 14a is provided in the vicinity of the right end portion of the plate portion 14, and is connected to the storage box 30 (air chamber 30a) in the vicinity of the left end portion of the plate portion 14. By providing the second connection port 36, the duct portion 34 can be formed by making the most of the entire width of the plate portion 14 to the maximum, so that the overall length of the duct portion 34 can be maximized. There is an advantage that the bass range can be enhanced more effectively.

また、前記中枠１６の左端部側に収容箱体３０(スピーカユニット２８)を設けると共に、該収容箱体３０の第１接続口３２に連通接続する第２接続口３６(突出部３５)を当該収容箱体３０に近接する板部１４の左端部側に設ける構成では、板部１４の裏側において、ダクト部を単に左方から右方に向けて上下方向の幅員が大きくなるように形成した場合(すなわち実施例におけるメインダクト部３４ａのみを形成する場合)に、該板部１４の左側部にダクト部として利用されていないスペースが生ずることとなる。そこで、実施例のように、ダクト部３４として、板部１４の左右方向の幅寸法を利用してこのスペースに左右方向に蛇行状に折返すサブダクト部３４ｂを形成することで、当該ダクト部３４の全長をより長くし得るから、スピーカユニット２８から出力される低音域を増強してより迫力や臨場感に優れた遊技が可能となる利点がある。なお、実施例では、前記板部１４より上方に突出するよう形成した前記突出部３５内にもダクト部３４(サブダクト部３４ｂ)を形成してあるから、ダクト部３４の全長をより長くすることが可能である。 In addition, a housing box 30 (speaker unit 28) is provided on the left end side of the middle frame 16, and a second connection port 36 (protruding portion 35 ) that communicates with the first connection port 32 of the housing box 30. In the configuration provided on the left end side of the plate portion 14 close to the housing box 30, the duct portion is formed on the back side of the plate portion 14 so that the width in the vertical direction increases simply from the left to the right. In this case (that is, when only the main duct portion 34a in the embodiment is formed), a space that is not used as a duct portion is formed on the left side portion of the plate portion 14. Therefore, as in the embodiment, the duct portion 34 is formed by forming a sub-duct portion 34b that folds in the left-right direction in the space by using the width dimension of the plate portion 14 in the left-right direction. Therefore, there is an advantage that the game can be made more powerful and realistic by enhancing the low frequency range output from the speaker unit 28. In the embodiment, since the duct portion 34 (sub-duct portion 34b) is also formed in the projecting portion 35 formed so as to project upward from the plate portion 14, the overall length of the duct portion 34 is made longer. Is possible.

ところで、前記スピーカユニット２８、および該スピーカユニット２８を制御する音声制御装置４２の夫々を、相対的に開閉する部材(例えば外枠１２と中枠１６や、中枠１６と前枠１８等)に、別々に配設するよう構成した場合には、中枠１６(前枠１８)を外枠１２(中枠１６)に対して開閉した際に、該スピーカユニット２８と音声制御装置４２とを接続する配線を噛み込んで断線を生ずる虞がある。殊に、前記中枠１６や前枠１８は、パチンコ機１０のメンテナンス等に際して開閉される頻度が高いことから、該中枠１６や前枠１８の開閉に際して、作業者に無用の注意負担を強いることとなり、作業が煩雑になる欠点が指摘される。これに対して、実施例では、前記スピーカユニット２８および音声制御装置４２の夫々を前記中枠１６に配設し、前記板部１４の裏側(外枠１２)にはダクト部３４のみを設ける構成としたことで、中枠１６を開閉した際にスピーカユニット２８と音声制御装置４２とを接続する配線を噛み込むことがなく、メンテナンス等の作業性が向上する利点がある。 By the way, the speaker unit 28 and the voice control device 42 that controls the speaker unit 28 are respectively connected to members that open and close relatively (for example, the outer frame 12 and the inner frame 16, the inner frame 16 and the front frame 18). If the middle frame 16 (front frame 18) is opened and closed with respect to the outer frame 12 (middle frame 16), the speaker unit 28 and the audio control device 42 are connected. There is a possibility that the wiring to be bitten may cause disconnection. In particular, since the middle frame 16 and the front frame 18 are frequently opened and closed during maintenance of the pachinko machine 10 and the like, an unnecessary caution burden is imposed on the operator when the middle frame 16 and the front frame 18 are opened and closed. In other words, the disadvantage that the work becomes complicated is pointed out. On the other hand, in the embodiment, each of the speaker unit 28 and the sound control device 42 is disposed in the middle frame 16 and only the duct portion 34 is provided on the back side (outer frame 12) of the plate portion 14. Thus, there is an advantage that workability such as maintenance is improved without biting the wiring connecting the speaker unit 28 and the voice control device 42 when the middle frame 16 is opened and closed.

なお、実施例では、前記スピーカユニット２８の前面側に第１カバー部材３８を設けるようにしたから、該スピーカユニット２８の損傷を防止できる。また同様に、前記ダクト部３４が外部に開口する第２の開口部１４ａに第２カバー部材４０を設けたことで、該ダクト部３４内に遊技者の手指や異物が挿入されるのを防止でき、該ダクト部３４の損傷等を防ぐことができる。なお、前記第１および第２カバー部材３８,４０の夫々をメッシュ状に形成したので、前記スピーカユニット２８の前面側から出力される音や、ダクト部３４から出力される音波が伝播するのを阻害することはない。 In the embodiment, since the first cover member 38 is provided on the front side of the speaker unit 28, the speaker unit 28 can be prevented from being damaged. Similarly, the second cover member 40 is provided in the second opening portion 14a where the duct portion 34 opens to the outside, thereby preventing a player's fingers and foreign objects from being inserted into the duct portion 34. It is possible to prevent the duct portion 34 from being damaged. Since each of the first and second cover members 38 and 40 is formed in a mesh shape, the sound output from the front side of the speaker unit 28 and the sound wave output from the duct portion 34 are propagated. There is no inhibition.

〔変更例〕
なお、本発明に係る遊技機としては、実施例のものに限られるものではなく、種々の変更が可能である。
実施例では、第２接続口を開設する第２当接部を外枠から上方に突出するよう形成したが、これに限定されるものではない。例えば、図６または図７に示すように、外枠１２の板部１４に、前方および上方に開口する凹部(第２当接部)５０を形成し、該凹部５０に前方へ向けて開口する第２接続口３６を開設すると共に、弾性材からなるシール材３７を設ける。また、中枠１６に、前記凹部５０に略整合する突起部(第１当接部)５２を形成すると共に、該突起部５２に、凹部５０の第２接続口３６に連通接続可能な第１接続口３２を後方へ向けて開口するよう開設してもよい。この場合も、前記中枠１６を外枠１２に対して閉成した際に第１突起部５２が凹部５０のシール材３７に圧接(密着)して、前記第１接続口３２および第２接続口３６が密閉状態で連通接続するよう構成すれば、実施例と同様の作用効果を得ることができる。 [Example of change]
Note that the gaming machine according to the present invention is not limited to the embodiment, and various modifications can be made.
In the embodiment, the second contact portion that opens the second connection port is formed so as to protrude upward from the outer frame. However, the present invention is not limited to this. For example, as shown in FIG. 6 or FIG. 7, a concave portion (second contact portion) 50 that opens forward and upward is formed in the plate portion 14 of the outer frame 12, and the concave portion 50 opens forward. While opening the 2nd connection port 36, the sealing material 37 which consists of elastic materials is provided. In addition, a projection (first contact portion) 52 that substantially matches the recess 50 is formed in the inner frame 16, and a first connection that can be connected to the second connection port 36 of the recess 50 to the projection 52. You may open so that the connection port 32 may open toward back. Also in this case, when the middle frame 16 is closed with respect to the outer frame 12, the first protrusion 52 comes into pressure contact (contact) with the sealing member 37 of the recess 50, and the first connection port 32 and the second connection are connected. If the mouth 36 is configured to be connected in a sealed state, the same effects as the embodiment can be obtained.

実施例では、ダクト部を外枠の板部の裏側で左右方向に折返す蛇行状に形成するようにしたが、これに限らず、図８に示すように、ダクト部５４を該板部１４の裏側で上下方向に折返す蛇行状に形成することも可能である。この場合には、ダクト部５４の全長を、前記板部１４の上下の幅寸法を利用して長くすることができるから、スピーカユニット２８から出力される低音域を効果的に増強して迫力や臨場感に優れると共に、所謂歯切れのよい高音質(高品質)な音を出力することが可能となる。 In the embodiment, the duct portion is formed in a meandering shape that folds back in the left-right direction on the back side of the plate portion of the outer frame. However, the present invention is not limited to this, and as shown in FIG. It is also possible to form a meandering shape that folds up and down on the back side. In this case, since the overall length of the duct portion 54 can be increased by utilizing the upper and lower width dimensions of the plate portion 14, the bass range output from the speaker unit 28 can be effectively enhanced and It is possible to output so-called crisp high-quality sound (high quality) as well as excellent realism.

実施例では、外枠の板部に形成するダクト部を第２接続口から第２の開口部に近づくにつれて幅員が増大する、所謂バックロードホーンタイプに形成したが、これに限られるものではない。例えば、図９または図１０に示すように、板部１４の裏側に、左右方向に延在し、かつ幅員が一定なダクト部５６を形成すると共に、板部１４の所要位置(図９または図１０では左右方向の略中央位置)に第２の開口部５８を開設するよう構成して、収容箱体３０とダクト部５６により所謂位相反転形のエンクロージャ構造をなすようにしてもよい。このように、位相反転形のエンクロージャ構造を採用し、スピーカユニット２８の背面側から出力された音波の位相を反転させたもとで前記板部１４の第２の開口部５８から出力することで、スピーカユニット２８の前面側から出力された音波と同じ位相として低音域の音を増強して鮮明な音の再生を可能とし得る。この場合も、例えば実施例と同様に、収容箱体３０の後壁部３１に後方に開口する第１接続口３２を開設すると共に、板部１４より上方に突出するよう形成した突出部３５に前方に開口する第２接続口３６を開設することで、中枠１６を外枠１２に対して閉成した際に後壁部３１が突出部３６(シール材３７)に圧接して、第１接続口３２および第２接続口３６を密閉状態で連通接続することができる。 In the embodiment, the duct portion formed on the plate portion of the outer frame is formed in a so-called back load horn type in which the width increases as it approaches the second opening from the second connection port, but is not limited thereto. . For example, as shown in FIG. 9 or FIG. 10, a duct portion 56 extending in the left-right direction and having a constant width is formed on the back side of the plate portion 14, and a required position of the plate portion 14 (FIG. 9 or FIG. 10, the second opening 58 may be opened at a substantially central position in the left-right direction, and the housing box 30 and the duct portion 56 may form a so-called phase-reversed enclosure structure. In this way, the phase-inverted enclosure structure is employed, and the sound wave output from the back side of the speaker unit 28 is inverted, and the sound is output from the second opening 58 of the plate portion 14, thereby the speaker. It is possible to reinforce the sound in the low frequency range with the same phase as the sound wave output from the front side of the unit 28, thereby enabling clear sound reproduction. Also in this case, for example, as in the embodiment, the first connection port 32 that opens rearward is formed in the rear wall portion 31 of the housing box 30 and the protruding portion 35 formed to protrude upward from the plate portion 14 is provided. By opening the second connection port 36 that opens forward, the rear wall portion 31 comes into pressure contact with the protruding portion 36 (seal member 37) when the middle frame 16 is closed with respect to the outer frame 12, and the first The connection port 32 and the second connection port 36 can be connected in a sealed state.

更に、図１０に示す前記板部１４に、前記第２の開口部５８から後方(ダクト部５６内)へ延在する筒状のバスレフポート６０を形成したバスレフタイプとするようにしてもよい(図１１参照)。この場合には、ダクト部５６の内容積と、バスレフポート６０の長さを調整することで、増強する低音域の周波数を変更することができる。なお、図８〜図１１において、実施例と同一の機能を有する部材には同一の符号を付してある。また、符号５９は変更例に係る第２の開口部５８に取付けられた第２カバー部材(カバー部材)を示すものである。 Further, the plate portion 14 shown in FIG. 10 may be of a bass reflex type in which a cylindrical bass reflex port 60 extending rearward (in the duct portion 56) from the second opening 58 is formed ( (See FIG. 11). In this case, by adjusting the internal volume of the duct portion 56 and the length of the bass reflex port 60, the frequency of the bass range to be enhanced can be changed. 8 to 11, members having the same functions as those in the embodiment are denoted by the same reference numerals. Reference numeral 59 denotes a second cover member (cover member) attached to the second opening 58 according to the modified example.

なお、図９に示す変更例のパチンコ機１０では、スピーカユニット２８を制御する音声制御装置４２を、遊技盤の裏側に配置する構成を採用している。このように、中枠１６に配設される遊技盤の裏側にスピーカユニット２８を制御する音声制御装置４２を配置するようにしても、中枠１６を開閉した際に該スピーカユニット２８と音声制御装置４２とを接続する配線を噛み込むのを防止することができる。 In addition, in the pachinko machine 10 of the modified example shown in FIG. 9, the structure which arrange | positions the audio | voice control apparatus 42 which controls the speaker unit 28 on the back side of a game board is employ | adopted. As described above, even if the voice control device 42 for controlling the speaker unit 28 is arranged on the back side of the game board disposed in the middle frame 16, the voice control with the speaker unit 28 is performed when the middle frame 16 is opened and closed. It is possible to prevent the wiring connecting the device 42 from being bitten.
