Description

  The present invention relates to a gaming machine, and more particularly to a gaming machine in which a speaker is installed on the back side of a waist plate.

  In general, a gaming machine such as a pachinko machine is provided with a speaker for producing sound effects by producing various sound effects (winning sounds, etc.) in various gaming states. Conventionally, the lower part on the front side of the middle frame is often used as a speaker installation part, but a relatively small speaker has been used due to the limited installation space. On the other hand, recently, in order to improve the taste in gaming machines, higher sound quality is desired. However, although improvements have been made year by year, powerful speakers cannot be obtained with a small speaker, and the player cannot be fully satisfied.

  Therefore, in recent years, a pachinko machine has been proposed in which a sound generating means such as a speaker is installed on the back side of the waist plate (curtain board) at the lower part of the outer frame in order to realize powerful sound production with good sound quality ( For example, see JP-A-2003-79834. That is, the back side of the waist plate is not subject to space restrictions, and a relatively large speaker can be installed.

Japanese Patent Laid-Open No. 2003-79834 (see FIG. 6 etc.)

  However, in the case of a structure in which a speaker is disposed on the back side of the waist plate, it is conceivable that the speaker itself or the front side of the waist plate including the through hole portion of the speaker is soiled or damaged due to mischief. If the speaker itself is damaged, it may cause problems such as deterioration in sound quality or no sound at all. For this reason, troublesome work such as once removing the gaming machine from the gaming island and replacing the speaker is required. If the front side of the lumbar plate is damaged, the sound quality is not lowered, but a troublesome work of once removing the gaming machine from the gaming island and replacing the entire outer frame is required.

  In addition, there are a number of requests that some game stores want to easily change the design on the front side of the waist plate.

  The present invention has been made in view of the above problems, and an object thereof is to provide a gaming machine that can prevent dirt and damage due to mischief and can easily change the design of the front side of the waist plate. It is in.

  In order to solve the above-mentioned problem, in the invention described in claim 1, the present invention includes a waist plate constituting a lower part of the outer frame, and a speaker having a sound generation unit on the front side, and the sound generation is performed in an opening formed in the waist plate. A first cover member having a plurality of first speaker through holes provided in the opening of the waist plate in a gaming machine in which the speaker is placed on the back side of the waist plate so as to face the portion, In order to cover the entire front surface of the waist plate, it is detachably attached to the front side of the waist plate by engagement means disposed on the back side of the waist plate, and a plurality of second plates are provided at positions corresponding to the first cover member. The gist of the gaming machine includes a second cover member having a two-speaker through hole.

  Therefore, according to the first aspect of the present invention, the front side of the waist plate is covered and protected by the second cover member. As a result, the front side of the waist plate is less likely to be mischievous, and dirt and breakage can be prevented. Further, since the speaker is double-covered and protected by the first cover member and the second cover member, the speaker can be reliably prevented from being soiled or damaged by mischief. Furthermore, since the second cover member can be attached to and detached from the front side of the waist plate, the design can be changed relatively easily by replacing the second cover member as necessary. Further, since the entire front surface of the waist plate is covered, not only the speaker but also the entire front surface of the waist plate is protected. Further, since the engaging means that allows the second cover member to be attached / detached is disposed on the back side of the waist plate, there is no fear that the waist plate is illegally attached / detached from the front side of the waist plate.

  The gist of a second aspect of the present invention is that, in the first aspect, the first cover member has a shape in which a substantially central portion is recessed toward the speaker.

  Therefore, according to the second aspect of the present invention, the distance between the substantially central portion of the first cover member recessed toward the speaker side and the second cover member is increased. Therefore, even if an illegal foreign matter such as a wire is inserted into the second cover member through the second speaker through hole, the tip of the foreign matter is unlikely to reach the first cover member. As a result, the first cover member and the speaker can be prevented from being dirty or damaged. Moreover, since the area which can form the 1st speaker through-hole part in a 1st cover member increases in such a shape, for example, a large 1st speaker through-hole part can be formed without much difficulty. . As a result, the sound generated by the speaker can surely reach the front side of the first cover member. As a result, it is difficult for the sound to be confined. As a result, it is possible to prevent deterioration in sound quality, and the speaker can easily exhibit its performance.

  Here, about the 2nd cover member, it is good to have the shape which swelled on the opposite speaker side (namely, player side) conversely, and by configuring in this way, the 1st cover member and the 2nd cover member Can be further increased.

  The shape of the first speaker through-hole portion and the shape of the second speaker through-hole portion are not particularly limited and can be arbitrarily set, but are preferably different from each other rather than being the same (claim 3). .

  Therefore, according to the third aspect of the present invention, even if an unauthorized foreign object is inserted into the second cover member through the second speaker through hole, the shape differs from that of the second speaker through hole. If the 1-speaker through-hole portion is set, it becomes difficult for the tip of the foreign matter to reach the inside of the first cover member through the first speaker-through-hole portion. As a result, it is possible to reliably prevent the speaker from being dirty or damaged.

  Further, the size relationship of the opening area of the first speaker through hole and the second speaker through hole is not particularly limited and can be arbitrarily set. For example, the opening area of the second speaker through hole is, for example, Is preferably smaller than the opening area of the first speaker through hole. With this configuration, since it is difficult to insert illegal foreign substances into the second speaker through-hole portion having a small opening area, mischief can be suppressed at the second cover member. In addition, since the sound generated by the speaker can surely reach the front side of the first cover member, the sound is less likely to be trapped, so that the sound quality can be prevented from being deteriorated, and the speaker exhibits its performance sufficiently. It becomes easy to do.

  It is preferable that the first cover member and the second cover member are arranged at a predetermined interval.

  With this configuration, even if an unauthorized foreign object is inserted into the second cover member via the second speaker through hole, the tip of the foreign object is difficult to reach the first cover member. As a result, the first cover member and the speaker can be prevented from being dirty or damaged.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the back surface of the second cover member is provided with a protrusion capable of contacting the front surface of the waist plate. The gist.

  Therefore, according to the fourth aspect of the present invention, as a result of the second cover member being entirely reinforced by the protrusions, the second cover member is hardly deformed. Moreover, a 2nd cover member can be stably fixed because a protrusion contact | abuts with respect to the waist plate front surface. Therefore, even when a loud sound is generated in the speaker, there is no concern that the vibration causes the second cover member to rattle and generate noise.

  Here, it is sufficient that the second speaker through hole penetrates the front surface and the back surface of the second cover member. For example, the second speaker through hole portion is formed obliquely upward from the back surface side to the front surface side of the second cover member. (Claim 5). With such a configuration, the front end opening of the second speaker through-hole portion faces the player, so that the sound emitted from the speaker can easily reach the player's ear. In addition, the second speaker through hole may be formed, for example, obliquely downward from the back surface side to the front surface side of the second cover member. If the second speaker through-hole portion is facing downward, it becomes difficult to insert an unauthorized foreign object, so that it is possible to more reliably prevent mischief by the player.

  Moreover, the bass-reflex formable part which has several non-through-holes may be provided in the approximate center part of the said 2nd cover member.

  With this configuration, the through holes can be easily formed at desired locations by drilling the plurality of non-through holes in the bass reflex formable portion as necessary. Therefore, the through hole formed in this way can be used as a sound outlet of a bass reflex duct in a bass reflex speaker (phase reversal speaker).

  As described above in detail, according to the first to sixth aspects of the present invention, there is provided a gaming machine that can prevent dirt and damage due to mischief and can easily change the design of the front side of the waist plate. be able to.

For example, at a position above the center of the mechanism set board 23 (specifically, a position almost on the back side of the symbol display device 18 attached to the game board 13), a board case 31 for accommodating the symbol control board 31D therein. Is arranged. In addition, a board case 31 that houses the lamp control board 31C is disposed at a lower left side position of the board case 31 that houses the symbol control board 31D. As shown in FIG. 2, these substrate cases 31 are relatively large components having an outer dimension of 10 cm square or more, and are all disposed above the waist plate unit 11B.

  As shown in FIGS. 2, 3, 6, and the like, the waist plate unit 11 </ b> B of the present embodiment that constitutes the lower part of the outer frame 11 is located below the ball tray mounting portion, and includes the unit upper wall 41, unit It consists of a lower wall 42, a pair of unit side walls 43, 44 and a unit front wall 45. The unit front wall 45 that is a speaker installation part is a flat wall-shaped part that partitions the player side and the pachinko machine 10 side (that is, partitions the inside and outside of the pachinko machine 10). On the front side of the unit front wall 45, a waist plate cover 81 (see FIG. 4, FIG. 5, etc.) as a second cover member that entirely covers the waist plate unit 11B is detachably fixed. . Details of the waist plate cover 81 will be described later.

  As shown in FIG. 6, slits 46 are formed at two locations on the unit lower wall 42 for driving nails when the outer frame 11 is attached to a game island (not shown). Further, a substantially L-shaped reinforcing rib 47 for reinforcing the waist plate unit 11B is integrally formed on the upper surface of the unit lower wall 42 and the rear surface of the unit front wall 45. The inner surface of the unit side wall 43 positioned on the left side when viewed from the back side of the machine and the inner surface of the unit side wall 44 positioned on the right side when viewed from the back side of the machine are respectively substantially U-shaped for reinforcing the waist plate unit 11B. A reinforcing metal fitting 48 is attached.

  As shown in FIGS. 1, 4 and 5, a synthetic resin waist plate cover 81 covering the entire front surface of the unit front wall 45 is detachably attached to the front surface side of the waist plate unit 11B. That is, the area of the front plate 82 of the waist plate cover 81 has substantially the same size as the area of the unit front wall 45. Thus, the waist plate unit 11B is covered and protected by the waist plate cover 81. The waist plate cover 81 includes a front plate 82 formed in a horizontally long rectangular shape, a pair of side plates (a right side plate 83 and a left side plate 84) positioned on the left and right sides of the front plate 82, and an upper plate positioned above the front plate 82. 85. R (R) is provided at a connecting portion between the front plate 82 and the right side plate 83 and a connecting portion between the front plate 82 and the left side plate 84. A bulging portion 91 that bulges toward the front of the cover is formed in the upper region of the connecting portion between the front plate 82 and the left side plate 84. The bulging portion 91 is formed corresponding to the convex portion T1 (see FIG. 3) on the front side of the waist plate unit 11B.

  As shown in FIGS. 4, 5, and the like, raised portions 90 that are raised by about 1 mm to 2 mm are formed at two spaced locations on the upper surface of the upper plate 85. On the upper surface of these raised portions 90, the lower end portion is placed when the lower ball tray 16 is mounted. At this time, since the upper end edge (upper plate 85) of the waist plate cover 81 is pressed from above by the lower end portion of the lower ball tray 16, the upward movement of the waist plate cover 81 is restricted. In addition, an inclined surface 90 a is formed at the front end portion of the raised portion 90 to guide and place the lower ball tray 16 easily. The inclined surface 90a is inclined so as to increase from the front to the rear of the cover.

  On the back surface of the front plate 82, a plurality of locking pieces 93 and 94, which are a plurality of locking portions, are projected. Two locking pieces 93 are arranged at both the left and right end portions on the back surface of the front plate 82, and the locking pieces 94 that are slightly wider than these are arranged in two steps at a substantially central portion on the back surface of the front plate 82. Yes. That is, when the waist plate cover 81 is viewed from the back side, the left side locking piece 94 is at a slightly lower position, and the right side locking piece 94 is at a slightly higher position. The protruding amount of the locking pieces 93 and 94 is set larger than the protruding amount of the cover reinforcing rib 92.

  As shown in FIG. 3, a locked portion 103 to which the locking piece 93 can be engaged and disengaged is formed at a position corresponding to the locking piece 93 in the unit front wall 45 of the waist plate unit 11B. At a portion corresponding to 94, a locked portion 104 to which the locking piece 94 can be engaged and disengaged is formed. Specifically, these locked portions 103 and 104 are holes formed through the unit front wall 45, and a projecting piece that is a substantially locked portion is provided at the lower edge of each hole. Yes. Accordingly, the waist plate cover 81 is moved in the direction from the top to the bottom to engage the locking piece 93, while the waist plate cover 81 is moved in the direction from the bottom to the top. The locking of the locking piece 93 is released. In addition, the two to-be-latched parts 104 which the latching piece 94 latches are arrange | positioned in steps. That is, when the waist plate unit 11B is viewed from the front side, the left locked portion 104 is at a slightly higher position, and the right locked portion 104 is at a slightly lower position.

  As shown in FIGS. 2 and 6, an empty space is generated in the central portion on the back side of the unit front wall 45. A restriction member 111 (engagement means) made of synthetic resin is disposed in the empty space. The restriction member 111 is configured to be movable between a restriction position and a restriction release position.

  As shown in FIG. 7, the restriction member 111 in the present embodiment has a structure in which a lever 113 that can be operated with a fingertip is provided at one end of a horizontally long restriction member main body 112. Claw portions 114 are formed at three positions in the regulating member main body 112 at intervals. The tips of the claw portions 114 always protrude slightly from the surface of the regulating member main body 112.

  On the other hand, as shown in FIG. 2, a pair of left and right insertion portions 121 are provided at a substantially central portion on the back side of the unit front wall 45. The insertion part 121 is located between the two locked parts 104 and 104 (see FIG. 3). The restriction member main body 112 of the restriction member 111 is inserted into the insertion portion 121 in a state in which the restriction member main body 112 can slide in the lateral direction.

  As shown in FIG. 2, when the regulating member 111 is in the regulated position, the lower surface side of the regulating member 111 is in contact with the upper surfaces of the two locking pieces 94. Further, when one of the claw portions 114 is locked to the side surface of the insertion portion 121, the restriction member 111 is held and fixed at that position. Accordingly, at this time, the upward movement of the locking piece 94 in the locked state is regulated by the regulating member 111. Therefore, the waist plate cover 81 cannot be moved upward to unlock the locking pieces 93 and 94, and the waist plate cover 81 cannot be removed.

  When the restriction member 111 moves from the restriction position to the restriction release position, the lower surface side of the restriction member 111 is not in contact with the two locking pieces 94. Further, when one or two of the claw portions 114 can be locked to the side surface of the insertion portion 121, the restriction member 111 is held and fixed at substantially the position. Therefore, at this time, the upward movement of the locking piece 94 in the locked state is not regulated by the regulating member 111 at all. Therefore, the waist plate cover 81 can be shifted upward to unlock the locking pieces 93 and 94, and the waist plate cover 81 can be removed.

  As shown in FIGS. 3 and 8, the unit front wall 45 of the waist plate unit 11 </ b> B is formed with a pair of left and right oval openings 52 that allow the front and rear surfaces of the unit front wall 45 to communicate with each other. As shown in FIGS. 2, 6, and 8, various sounds (such as sound effects) are output to positions corresponding to the pair of openings 52 on the back side of the unit front wall 45 according to the state of the game. Speakers 51 are respectively provided. The speaker 51 has a horizontally long circular shape (see FIG. 2 and the like) and includes a metal frame 61 having a bulk shape. On the front side of the speaker 51, a cone paper 55 is provided as a diaphragm (sound generator) protected by the frame 61. An elastic protective cover 71 is fitted to the center of the back surface of the frame 61. The protective cover 71 of this embodiment is formed in a substantially cup shape using rubber (for example, NBR) which is a kind of elastic body as a material. A circular window 72 is formed through the central portion of the upper surface of the protective cover 71. These speakers 51 are installed so that the cone paper 55 faces the opening 52, and the four corners are fixed to the unit front wall 45 with screws from the back side. Therefore, the front side and the rear side of these speakers 51 are blocked by the unit front wall 45 (see FIG. 8). Further, as shown in FIG. 8, the rear space 56 of the speaker 51 is not provided with any other member (for example, the substrate case 31) that can be a sound shield or a sound reflector. For this reason, the rear space 56 of the speaker 51 is completely open.

  As shown in FIGS. 3 and 8, cover engaging portions 52 a are respectively formed on the back side of the unit front wall 45 in the pair of openings 52. A vibrating body cover 53 as a first cover member is fitted and fixed to each opening 52 from the back side of the unit front wall 45. The vibrating body cover 53 is a resin molded product made of a light-transmitting resin and has an elliptical shape similar to that of the opening 52. A flange portion 53 a is formed on the outer peripheral portion of the vibrating body cover 53.

  As shown in FIG. 8, the vibrating body cover 53 includes a flange portion 53a and a wall portion 53b. The width of the flange portion 53a is equal to the width of the bottom surface of the cover engaging portion 52a. The wall portion 53 b has the same length from the bottom surface of the cover engaging portion 52 a to the front surface of the unit front wall 45, and the outer surface can come into contact with the opening portion 52. That is, the flange portion 53a has a shape that can be engaged with the cover engaging portion 52a. Therefore, the vibrating body cover 53 is fixed to the opening 52 by engaging the flange portion 53 a with the cover engaging portion 52 a. At this time, the front surface of the outer peripheral portion of the vibrating body cover 53 is flush with the front surface of the unit front wall 45.

  In addition, the vibrating body cover 53 has a substantially cross-sectional shape in which a substantially central portion (through hole forming region 57) is recessed toward the speaker 51 side. Thereby, the distance between the through hole forming region 57 and the front plate 82 of the waist plate cover 81 is increased. In the through hole forming region 57, a plurality of vibrating body cover side through holes 54 (first speaker through holes) that communicate the front and back of the vibrating body cover 53 are provided so as to extend along the horizontal direction. Yes. That is, the height position of the front end opening of the vibrating body cover side through-hole portion 54 is equal to the height position of the rear end opening. Of each vibrating body cover side through hole portion 54, the central vibrating body cover side through hole portion 54 has an elliptical shape similar to the opening 52 and the vibrating body cover 53, and other vibrating body cover side through hole portions. 54 is a long hole extending parallel to the opening edge of the opening 52. The vibrating body cover side through-hole portions 54 have the same width and are arranged at equal intervals.

  As shown in FIGS. 4 and 5, a plurality of cover reinforcing ribs 92 (projections) extending in the vertical direction or the horizontal direction are formed on the back surface of the front plate 82 of the waist plate cover 81. The cover reinforcing rib 92 extending in the lateral direction at the lower end portion of the waist plate cover 81 extends not only across the entire lower end portion of the waist plate cover 81 but also extends to the entire lower end portions of the right side plate 83 and the left side plate 84. . The presence of these cover reinforcing ribs 92 reinforces the waist plate cover 81 as a whole, so that the waist plate cover 81 is less likely to be deformed. Each cover reinforcing rib 92 can come into contact with the front surface, right side surface, and left side surface of the unit front wall 45. For this reason, the waist board cover 81 can be stably fixed. At this time, the waist plate cover 81 is disposed so as to be separated from the vibrating body cover 53 by the height of the cover reinforcing rib 92 that contacts the unit front wall 45.

  As shown in FIG. 4 and the like, an inverted triangular decorative portion 88 (bass reflex forming portion) having a shape in which a flat isosceles triangular shape is reversed is provided at a position above the central portion on the front side of the front plate 82. Is formed. A large number of dummy holes 89 serving as circular non-through holes are formed in the inverted triangular decorative portion 88. These dummy holes 89 can be made through-holes by drilling as necessary. In addition, substantially elliptical decorative portions 86 are formed on the left and right side portions on the front side of the front plate 82 so as to be separated from each other. A number of waist plate cover side through-hole portions 87 (second speaker through-hole portions) that communicate the front and back of the front plate 82 are provided so as to extend along the horizontal direction at the locations where the substantially elliptical decorative portions 86 are located. It has been. That is, the height position of the front end opening of the waist plate cover side through hole portion 87 is equal to the height position of the rear end opening.

  Each waist plate cover side through-hole portion 87 is provided at a position corresponding to the vibrating body cover 53 on the front plate 82. The waist plate cover side through hole portion 87 has a circular shape different from the shape of the vibrating body cover side through hole portion 54 of the vibrating body cover 53. The inner diameter of the waist plate cover side through hole portion 87 is slightly smaller than the width of the vibrating body cover side through hole portion 54. Therefore, even if an illegal foreign matter such as a wire is inserted into the waist plate cover 81 through the waist plate cover side through hole portion 87, the tip of the foreign material is inside the vibration body cover 53 through the vibration body cover side through hole portion 54. It becomes difficult to reach.

  Next, a method for replacing the waist plate cover 81 will be described.

  First, the middle frame 12 is opened, the back side of the outer frame 11 is operable, the lever 113 is slid in the horizontal direction, and the regulating member 111 is moved from the regulated position to the regulated release position. Then, the lower surface of the restricting member 111 does not come into contact with the upper surfaces of the two locking pieces 94, and the locking pieces 93 and 94 are not prevented from coming off from the locked portions 103 and 104.

  Next, by moving the waist plate cover 81 from below to above, the engagement between each locking piece 93 and each locked portion 103 is released, and each locking piece 94 and each locked portion. The engagement with 104 is released. At this time, the engagement between the upper plate 85 of the waist plate cover 81 and the unit upper wall 41 of the waist plate unit 11B is also released. As a result, the waist plate cover 81 can be removed.

  Then, a waist plate cover different from the removed waist plate cover 81 is disposed. At this time, the waist plate cover can be easily mounted by basically performing the reverse of the above-described removal procedure. However, when the middle frame 12 and the like are closed and the rear side of the outer frame 11 is in an inoperable state, the mounting operation cannot be performed.

  Therefore, according to the present embodiment, the following effects can be obtained.

  (1) The front side of the waist plate unit 11B is covered and protected by the waist plate cover 81. Moreover, since the entire front surface of the waist plate unit 11B is covered, the entire front surface of the waist plate unit 11B is protected. As a result, the front side of the waist plate unit 11B is less likely to be mischievous, and dirt and damage can be prevented. Further, since the speaker 51 is double-covered and protected by the vibrating body cover 53 and the waist plate cover 81, dirt and damage of the speaker 51 due to mischief can be reliably prevented.

  Further, the waist plate cover 81 can be attached to and detached from the front side of the waist plate unit 11B. Therefore, it is possible to easily change the design of the waist plate cover 81 as necessary, or to replace the dirty waist plate cover 81 with a new one.

  Further, a regulating member 111 that allows the waist plate cover 81 to be attached and detached is disposed on the back side of the waist plate unit 11B. For this reason, since it is impossible to operate the restricting member 111 for those who cannot open the middle frame 12, the locking state between the locking pieces 93 and 94 and the locked portions 103 and 104 is determined. It cannot be released. Therefore, there is no fear that the waist plate unit 11B is illegally attached and detached from the front side of the waist plate unit 11B.

  (2) The vibrating body cover 53 has a shape in which a substantially central portion (through hole forming region 57) is recessed toward the speaker 51 side. Therefore, the distance between the through hole forming region 57 of the vibrating body cover 53 and the waist plate cover 81 is increased. Therefore, even if an illegal foreign matter such as a wire is inserted into the waist plate cover 81 through the waist plate cover side through hole 87, the tip of the foreign matter is unlikely to reach the vibrating body cover 53. As a result, the vibrating body cover 53 and the speaker 51 can be prevented from being dirty or damaged.

  In addition, with such a shape, an area in which the vibrating body cover side through-hole portion 54 can be formed in the vibrating body cover 53 is increased, and thus, for example, the large vibrating body cover side through-hole portion 54 can be formed without much difficulty. Can do. As a result, the sound generated by the speaker 51 can surely reach the front side of the vibrating body cover 53. As a result, it is difficult for the sound to be confined, and as a result, deterioration in sound quality can be prevented, and the speaker 51 can easily exhibit its performance.

  (3) Even if an illegal foreign object such as a wire is inserted into the waist plate cover 81 through the waist plate cover side through hole portion 87, the circular vibration body cover side through hole having a different shape from the waist plate cover side through hole portion 87 is used. If the hole portion 54 is set, it becomes difficult for the tip of the foreign matter to reach the inside of the vibrating body cover 53 via the vibrating body cover side through hole portion 54. As a result, the dirt and damage of the speaker 51 can be reliably prevented.

  (4) As a result of the overall reinforcement of the waist plate cover 81 by the cover reinforcing rib 92, the waist plate cover 81 is less likely to be deformed. Moreover, the waist plate cover 81 can be stably fixed because the cover reinforcing ribs 92 abut against the front surface, the right side surface, and the left side surface of the unit front wall 45. Therefore, even when a loud sound is generated in the speaker 51, there is no concern that the waist plate cover 81 will rattle due to vibration and cause noise.

  In addition, you may change embodiment of this invention as follows.

  In the above-described embodiment, the vibrating body cover 53 has a shape in which the substantially central portion is recessed toward the speaker 51 side, but the vibrating body cover 53 may be formed in a flat plate shape.

  In the above embodiment, the vibrating body cover side through-hole portion 54 in the waist plate unit 11B is formed larger than the waist plate cover-side through hole portion 87 in the waist plate cover 81, but this magnitude relationship may be changed. . Further, the shape of the vibrating body cover side through hole portion 54 and the shape of the waist plate cover side through hole portion 87 may be the same.

  In the above embodiment, as shown in FIG. 8, the waist plate cover side through hole 87 in the waist plate cover 81 is formed so as to extend along the horizontal direction. That is, the height position of the front end opening of the waist plate cover side through-hole portion 87 was equal to the height position of the rear end opening. However, the present invention is not limited to this. For example, as shown in FIG. 9, the height position of the front end opening of the waist plate cover side through hole 87 may be higher than the height position of the rear end opening. . As described above, when the waist plate cover side through-hole portion 87 is inclined upward from the back surface side of the waist plate cover 81 toward the front surface side, the front end opening of the waist plate cover side through-hole portion 87 faces the player. Therefore, there is an advantage that the sound emitted from the speaker 51 can easily reach the player's ear. On the contrary, as shown in FIG. 10, the height position of the front end opening of the waist plate cover side through-hole portion 87 may be made lower than the height position of the rear end opening. As described above, when the waist plate cover side through-hole portion 87 is inclined downward from the back surface side to the front surface side of the waist plate cover 81, it is difficult to insert illegal foreign objects such as wires, so that the player There is an advantage that mischief by can be prevented more reliably.

  In the above-described embodiment, the speaker 51 including the cone paper 55 (that is, the cone-shaped speaker) is used as the diaphragm, but instead of this, the speaker 51 is made of a material other than paper (for example, polymer, metal, cloth, ceramic, etc.). You may use the speaker provided with the cone. Further, the number and shape of the cones can be arbitrarily changed. Further, instead of the cone type speaker, for example, a horn type speaker, a dome type speaker, a flat / flat type speaker, an electrostatic type speaker, a piezoelectric type speaker or the like is allowed.
