  However, in the articles provided with the sound generation devices described in Patent Document 1 and Patent Document 2, functional parts necessary for the articles occupy a considerable portion of the exterior. For this reason, due to the positional relationship with the functional components, when the speaker, the circuit board, and the power source are arranged inside the main body, it is often necessary to employ a complicated arrangement configuration or a complicated wiring structure.

  In addition, when the functional parts appearing on the exterior increase, it is necessary to devise the arrangement position of the speaker and the operation position of the switch. Furthermore, if the switch operation part is made large in consideration of the convenience of operation, there may be a case where the installation space for the switch operation part cannot be secured.

  An object of the present invention is to arrange a speaker, a circuit board provided with a control circuit, and a power source using a limited internal space of the toy body even if the toy body has a large number of functional parts appearing outside. An object of the present invention is to provide a toy equipped with a sound generator capable of simplifying wiring and simplifying wiring.

  Another object of the present invention is to provide a toy equipped with a sound generator that can emit sound from a speaker without using a dedicated switch operation component.

  Another object of the present invention is to provide a toy provided with a sound generator capable of always stably displacing a speaker unit having a function as a switch operating component.

  Another object of the present invention is to provide a sound generator that can be easily assembled with a spring member that returns when the speaker unit is pressed, and that can reliably return the speaker unit with only one spring member. To provide toys.

  In the toy equipped with the sound generating device of the present invention, at least a part of a plurality of types of functional parts necessary for the function of the toy is arranged on the front and / or rear and side of the torso body. Therefore, most of the inside and outside of the toy body is occupied by functional parts. In the toy body, a speaker, a circuit board including a control circuit including at least a speaker driving circuit of the speaker, and a power source for supplying power to the control circuit are housed. This toy is used in a state where the bottom surface of the toy body is placed on the installation surface.

  In particular, in the toy equipped with the sound generating device of the present invention, the sound emission guard of the speaker is exposed on the outer surface of the upper part of the toy body located on the opposite side of the bottom surface of the toy body and above the trunk. Deploy. And a speaker is arrange | positioned under the sound emission guard in the upper part of a toy main body. A circuit board is arranged below the speaker. Further, a power source such as a battery or a storage battery is disposed in a lower portion located below the trunk portion of the toy main body. Then, the power supply and the control circuit are connected by the first electrical connection means, and the control circuit and the speaker are connected by the second electrical connection means. As the first and second electrical connection means, for example, a lead wire in which a conductive wire is covered with an insulating coating can be used.

According to the present invention, since at least a part of a plurality of types of functional parts necessary for the function of the toy is disposed on the front and / or rear and side of the trunk of the toy body, In a toy equipped with a sound generator that does not have much use space outside, a speaker is placed in the upper part of the toy body (the head in the case of a doll-shaped toy body) using the empty space in the vertical direction of the toy body. The circuit board is placed under the speaker, and the power supply is placed in the lower part located below the torso's trunk, so that the parts necessary for sound generation are neatly placed in a limited space. Can be incorporated. In addition, since the power source is disposed below the circuit board and the speaker is disposed above the circuit board and connected by the first and second electrical connection means, the electrical connection between the power source and the circuit board is achieved. The connection and the electrical connection between the circuit board and the speaker become simple, and the wiring used for the electrical connection can be shortened. Therefore, assembly of toys and internal electrical wiring can be facilitated. Furthermore, since the power source is arranged in the lower part of the toy body, the position of the center of gravity of the toy is lowered, and the toy installation posture can be stabilized.

  In addition to the above configuration, a switch component that includes an operated portion and that is operated when sound is output from the speaker is mounted on a surface of the circuit board located on the speaker side. A sound emission guard and a speaker are combined to form one speaker unit. The speaker unit configured as described above may be provided in the upper part of the toy main body via a guide mechanism so that the position is displaced by an external force. In this case, the speaker unit and the guide mechanism are configured so that the operated part of the switch component can be operated by the operation unit provided in the speaker unit by the displacement of the position of the speaker unit. When the speaker unit configured by combining the sound emission guard and the speaker as described above is used as a switch operation component for operating the switch component, a dedicated switch operation component is not necessary and a dedicated switch operation component is arranged. This eliminates the need for a space for the toy body. Therefore, in a toy with many functional parts mounted on the toy main body, the effect is extremely large.

In this toy, when no Tei added external forces on the sound output guard, the speaker unit is in the first position, when an external force is applied to the sound output guard speaker unit external force is applied from the first position The guide mechanism guides the speaker unit when moving toward the second position in the selected direction. The guide mechanism guides the speaker unit to return from the second position to the first position when the external force applied to the sound emission guard is removed. When such a guide mechanism is provided, the speaker unit can smoothly move up and down even when a large component is moved as in the speaker unit. Therefore, even if the speaker unit is used as a switch operation component, no particular problem occurs in operation.

  In particular, the speaker unit may include a speaker storage case having a speaker storage chamber in which an opening is closed by a sound emission guard and a speaker is stored, and an operation unit is provided on the bottom wall of the speaker storage case. Good. When configured in this way, it is preferable that the guide mechanism further includes a guide case including a storage chamber in which the speaker storage case is fitted so that the speaker storage case can slide without being inclined. When such a guide case is used, energy is stored between the guide case and the speaker storage case when the speaker unit moves from the first position to the second position, and is released when the external force is removed. A spring member to be urged is disposed. In addition, a through hole is formed in the bottom wall portion of the guide case, through which an operation portion provided in the speaker unit passes slidably. When a guide case is further added to the guide mechanism in this way, it is possible to prevent the speaker unit from moving up and down while being largely inclined when the speaker unit moves. Further, when such a configuration is adopted, the arrangement of the spring member used for the returning operation of the speaker unit is facilitated.

Furthermore, it is preferable that the sound emitting guard and / or the speaker storage case is provided with three or more guided protrusions at equal intervals in the circumferential direction. The guide case is formed with three or more slide grooves into which the three or more guided projections are slidably fitted. With this configuration, the speaker unit will be guided at two locations, upper and lower,
Regardless of the direction in which an external force is applied to the sound emitting cover, it is possible to reliably prevent a situation in which the slide unit tilts and cannot slide up and down.

  Further, a spring member having a coil shape is used, and the operation portion is integrally provided at the center portion of the bottom wall portion of the speaker storage case. And a through-hole is formed in the center part of the bottom wall part of a guide case, and the fitting recessed part by which the end of a spring member is fitted so that the through-hole of a guide case may be enclosed is formed. And the spring member is arrange | positioned between the guide case and the speaker unit in the attitude | position which penetrates the inside of the spring member fitted by the fitting recessed part, and the through-hole.

  If comprised in this way, the spring returned when a speaker unit is pushed can be incorporated stably.

According to the present invention, since at least a part of a plurality of types of functional parts necessary for the function of the toy is disposed on the front and / or rear and side of the trunk of the toy body, In a toy equipped with a sound generator that does not have much use space outside, a speaker is placed in the upper part of the toy body using the empty space in the vertical direction of the toy body, and a circuit board is placed under the speaker. Since the power source is arranged in the lower part located below the trunk part of the toy body, there is an advantage that the parts necessary for generating the sound can be assembled in a limited space in an orderly manner. In addition, since the power source is disposed below the circuit board and the speaker is disposed above the circuit board and connected by the first and second electrical connection means, the electrical connection between the power source and the circuit board is achieved. Connection and electrical connection between the circuit board and the speaker become simple, and the wiring used for the electrical connection can be shortened, and the toy assembly and the internal electrical wiring can be made easy. Benefits that can be obtained.

  In addition, when a speaker unit configured by combining a sound emission guard and a speaker is used as a switch operation component for operating a switch component, a dedicated switch operation component is not necessary and a dedicated switch operation component is arranged. The advantage that no space is required can be obtained.

  One example of the best mode for carrying out a toy equipped with the sound generator of the present invention will be described in detail with reference to FIGS. 1 to 4A, 4B, 4C, and 4D. 1A, 1B, and 1C are a front view, a plan view, and a right side view of a toy provided with the sound generator of this example, and FIG. 2 shows the toy provided with the sound generator of this example. The front view which shows the state divided | segmented by the division surface of FIG. 3, FIG. 3 (A) (B) is an expanded sectional view of the upper part of the toy provided with the sound generator of this example, and the expansion which shows the state which pressed down the sound emission guard 4A, 4B, 4C, and 4D are a plan view, a rear view, a front view, and a right side view of the plan view showing the speaker unit and its guide means used in this example.

  The toy provided with the sound generator of this example includes a toy body 1 formed by assembling exterior parts made of synthetic resin or the like and molded into a required shape. The toy main body 1 is generally divided into front and rear portions by a split surface 47 shown in FIG. 1B, and in particular, the body portion 7 is divided into two divided bodies 1a and 1b. Arms 3 that are functional parts necessary for the function of the toy are attached to both sides of the toy main body 1, and legs 5 are provided on both sides of the lower part thereof. A plurality of types of functional components 9 and 11 necessary for the function of the toy are arranged in front of and behind the trunk portion 7 of the toy main body 1. Incidentally, the functional component 9 is a door member, and is configured such that a spherical body having a recognition part is inserted into the door member by opening the door member. This spherical body is configured to be driven by a motor disposed therein. The functional component 11 is configured to insert a chip body having a recognition part. In this example, the sound content emitted from the speaker is changed depending on the combination of the spherical body inserted in the front and the chip body inserted in the rear.

  As shown in FIG. 2, the toy body 1 of the toy includes a speaker 13, a circuit board 15 including a control circuit including at least a speaker driving circuit of the speaker 13, and a power source for supplying power to the control circuit. A plurality of batteries 17 to be used are accommodated. In addition, illustration is abbreviate | omitted about the other structure in the toy main body 1. FIG. As described above, in this embodiment, a space for storing the recognition parts, a motor, and the like are arranged inside the trunk portion, and there is substantially no space for storing other parts. The toy body 1 is used with its bottom surface 19 placed on the installation surface.

As shown in FIG. 2, the control circuit of the power supply 17 and the circuit board 15, the conductor is connected by a first electrical connection means 23 made of coated lead wire with an insulating material. The control circuit of the circuit board 15 and the speaker 13 are connected by the second electrical connection means 25 made of a lead wire. Note that FIG. 2 is created for the purpose of showing the relationship of wiring, and does not completely match the actual wiring. The length of the lead wire used as the second electrical connection means 25 is such that the speaker unit moves in the vertical direction as will be described later, and this movement causes a connection failure between the electrode and the end of the lead wire. The length is set with some margin so that it does not occur.

  In the toy of this example, on the outer surface of the upper part 8 (the part corresponding to the head of the robot) of the toy body 1 located on the opposite side of the bottom surface 19 of the toy body 1 and above the torso 7, The sound emission guard 21 of the speaker 13 is arranged in an exposed state. In the central portion of the sound emission guard 21, a large number of sound emission holes 21a are provided so as to penetrate the guard body in the vertical direction, that is, in the thickness direction. Most of the sound emission guard 21 is fitted in an opening 22 provided at the top of the upper portion 8 of the toy main body 1 so as to be vertically movable.

  As shown in FIG. 3, in the upper portion 8 of the toy body 1, a speaker 13 is disposed below the sound emission guard 21, and a circuit board 15 is disposed below the speaker 13, and is positioned on the speaker 13 side of the circuit board 15. A switch component 27 is mounted on the surface. The switch component 27 used in this example is a push button switch generally called a tact switch. Therefore, the key top of the push button switch constitutes the operated portion 27 a of the switch component 27. In this example, when the operated part 27a (the key top of the push button switch) of the switch component 27 is pressed and the switch component 27 is turned on, the speaker drive circuit mounted on the circuit board 15 is in the operating state. Predetermined music, voice, and the like are output from the speaker 13. As described above, in this toy, the content of the sound output differs depending on the combination of the spherical body and the chip body each having a recognition part.

  As shown in FIG. 3, in this example, the sound emission guard 21 and the speaker 13 are combined to form one speaker unit 29. The actual speaker unit 29 includes a speaker storage case 37 having a speaker storage chamber 35 in which the opening is closed by the sound emission guard 21 and the speaker 13 is stored. The speaker storage case 37 is combined with the sound emission guard 21, and both are combined and integrated using a fitting structure or the like. On the bottom wall portion 37a of the speaker storage case 37, an operation portion 33 used for pressing the operated portion 27a (the key top of the push button switch) of the switch component 27 is integrally provided so as to protrude downward. Yes.

  The speaker unit 29 is provided in the upper part 8 of the toy main body 1 so as to be movable in the vertical direction through the guide mechanism 31 so that the position thereof is displaced by a downward external force applied to the sound emission guard 21. . In other words, the speaker unit 29 and the guide mechanism 31 are each configured such that the operated portion 27 a of the switch component 27 can be operated by the operation portion 33 provided in the speaker unit 29 by displacement of the position of the speaker unit 29. .

  The guide mechanism 31 positions and holds the speaker unit 29 at the first position shown in FIG. 3A when no external force is applied to the sound emission guard 21. When the external force is applied to the sound emission guard 21, the guide mechanism 31 is in the second position shown in FIG. 3B in which the speaker unit 29 is in the direction (downward) in which the external force is applied from the first position. The speaker unit 29 is guided so as to move toward it. Further, the guide mechanism 31 guides the speaker unit 29 when the speaker unit 29 returns from the second position to the first position when the external force applied to the sound emission guard 21 is removed.

  The guide mechanism 31 includes a guide case 39 having a storage chamber 38 into which the speaker storage case 37 can be slid without being inclined. In particular, in this example, a cylindrical guide portion 31 c into which the cylindrical outer peripheral wall portion 37 b of the speaker storage case 37 surrounding the lower portion of the speaker storage chamber 35 is fitted is a partition wall 39 a disposed inside the guide case 39. Is formed. When the speaker unit 29 moves up and down, the cylindrical outer peripheral wall portion 37b of the speaker storage case 37 slides inside the guide portion 31c. The gap between the outer peripheral wall portion 37b and the guide portion 31c is determined so as to exhibit a guide function.

In this example, as shown in FIG. 4, three guided protrusions 31 a are provided on the outer periphery of the sound emission guard 21 at equal intervals in the circumferential direction. The guided protrusion 31 a may be provided not in the sound emission guard 21 but in the speaker storage case 37, or may be provided in both the sound emission guard 21 and the speaker storage case 37. Then, as shown in FIG. 4, the guide case 39, three slide grooves 31b which three guided protrusions 31a is fitted slidably is formed. The upper portion of the speaker unit 29 is guided when the speaker unit 29 is moved up and down by fitting the guided protrusion 31a and the slide groove 31b. In this example, by configuring the guide mechanism 31 as described above, the speaker unit 29 is guided at two locations in the upper and lower directions. Therefore, even when an external force is applied to the sound emission guard 21 not from the vertical direction but from an oblique direction, a situation in which the speaker unit 29 tilts in the guide case 39 and the speaker unit 29 does not move does not occur. . As a matter of course, the speaker unit 29 may be guided at one place instead of guiding the speaker unit 29 at two places above and below as in this example. In the above example, three guided protrusions 31a and three slide grooves 31b are provided, but there may be three or more. The guided protrusions 31a and the slide grooves 31b are preferably provided at equal intervals in the circumferential direction.

  A through hole 43 is formed in the bottom wall portion 39b of the guide case 39 through which the operation portion 33 provided in the speaker unit 29 is slidably penetrated. A coil-shaped spring member 41 is disposed between the guide case 39 and the speaker storage case 37. The spring member 41 is stored when the speaker unit 29 moves from the first position to the second position, and is released when the external force applied to the sound emission guard 21 is removed. A fitting recess 45 into which one end of the spring member 41 is fitted is formed on the upper surface of the bottom wall portion 39b of the guide case 39 so as to surround the through hole 43 formed in the central portion of the bottom wall portion 39b of the guide case 39. A cylindrical wall portion 39c is integrally provided. The operation unit 33 described above passes through the inside of the spring member 41 fitted in the fitting recess 45 and the through hole 43.

  The toy provided with such a sound generator is configured such that the toy main body 1 is generally divided into front and rear by a split surface 47 shown in FIG. The speaker unit 29, the circuit board 15 and the power source 17 can be inserted and assembled from the openings of any of the divided bodies 1a and 1b through the openings of any of the divided bodies 1a and 1b in a state where the divided bodies 1a and 1b are divided. Although not shown, a groove for inserting the first electrical connection means 23 and the second electrical connection means 25 is provided in the divided body 1a or 1b on the side where the speaker unit 29, the circuit board 15 and the power supply 17 are incorporated. Yes.

  As shown in FIG. 3 (A), the toy equipped with the sound generating device having such a structure has a sound emission guard 21 of the speaker unit 29 provided exposed at the top of the upper portion of the toy main body 1 as an operator's finger. When the speaker unit 29 is pushed down, the speaker unit 29 is in a correct posture due to the guide action by the guided protrusion 31a and the slide groove 31b and the guide action by the outer surface of the speaker storage case 37 and the guide part 31c of the guide case 39. As shown in 3 (B), it descends. At this time, the spring member 41 is compressed and stored. At this time, when the speaker unit 29 is lowered, the operation portion 33 provided at the lower portion of the speaker storage case 37 presses the operated portion 27 a of the switch component 27 on the circuit board 15. As a result, sound is emitted from the speaker 13 by the action of the voice synthesis circuit portion of the control circuit on the circuit board 15, and is emitted to the outside through the many sound emission holes 21 a of the sound emission guard 21.

  When the operator's finger pressing down the sound emission guard 21 is withdrawn, the sound emission guard 21 returns to the state shown in FIG.

  Like this toy, since the speaker unit 29 is used as a switch operation part for operating the switch part 27, it is not necessary to provide a dedicated part for operating the switch part 27, and the structure of the sound generator is simplified. can do.

  In the above example, the guided protrusion 31 a is provided in the sound emission guard 21, but the present invention is not limited to this, and the guided protrusion 31 a can also be provided in the speaker storage case 37.
