Description

Technical Field

[0001] The present invention relates to a sound-emitting device, and more particularly to a sound-emitting device suitable for installation in a money box, a door, or the like.

Background Art

[0002] When a worshiper inserts money into a money box, it is considered that the worshiper feels comfort, sanctity, solemnity, etc. when sounds such as notification of money reception, sutra chanting, or benediction are emitted. Money boxes that emit such sounds have been proposed so far (for example, Patent Documents 1, 2, etc.).

[0003] On the other hand, various alarm devices have been proposed so far to prevent the theft of money from the money box or to prevent the theft of the money box itself containing money. For example, as a device that can be attached to an existing money box or the like, an alarm device that detects vibration, shaking, or inclination by the swing of a pendulum has been proposed (Patent Document 3, etc.).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the money boxes proposed in Patent Documents 1 and 2 cannot reliably detect the theft of money or the like. On the other hand, although the alarm device of Patent Document 3 can notify the theft of money or the like, there is a possibility that the pendulum swings due to the impact of the money inserted into the money box, causing the alarm device to operate and making the worshiper feel uncomfortable.

[0006] The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a sound-emitting device that, for example, when installed on an offering box, emits an alarm sound when the offering box or offerings are about to be stolen, and emits a sound that evokes feelings of comfort and sacredness in worshippers when offerings are placed in the offering box. [Means for solving the problem]

[0007] A sound-emitting device according to one aspect of the present invention that achieves the above objective is a sound-emitting device installed on an object that can change state from a stationary state, and is characterized by comprising: a first sensor that detects at least one of horizontal shaking and tilt changes of the object; a second sensor that detects vibrations of the object perpendicular to the surface on which the device is installed; a speaker that emits at least two types of sound; and control means that causes the speaker to emit different sounds when the first sensor detects something and when the second sensor detects something.

[0008] In the sound emitting device with the above configuration, the control means may, when it receives a detection signal from the first sensor while the speaker is emitting sound based on the detection signal from the second sensor, cause the speaker to prioritize emitting sound based on the detection signal from the first sensor.

[0009] Furthermore, the sound-emitting device having the above configuration may also be configured to be portable, further comprising a housing that houses the first sensor, the second sensor, the speaker, the control means, a power supply that supplies power to the speaker and the control means, and a switch that turns the power supply from the power supply on and off.

[0010] Furthermore, in the sound-emitting device with the above configuration, the first sensor may have a sphere, and the rolling of the sphere may detect at least one of horizontal shaking and tilt changes. In this case, the density of the sphere is 4.5 g / cm³. 3 It is preferable that the above conditions are met.

[0011] Furthermore, in the sound generating device with the above configuration, the first sensor may include a first plate-shaped member having a first conductive region on its upper surface, a second plate-shaped member positioned above the first plate-shaped member and spaced apart from the first plate-shaped member, penetrating in the vertical direction and having an opening with a second conductive region on at least a part of its inner circumferential surface, and a sphere positioned to roll within the first conductive region of the first plate-shaped member, with a portion of it located within the opening, and at least its surface being conductive, wherein the distance between the first plate-shaped member and the second plate-shaped member is shorter than the diameter of the sphere, the inner diameter of the opening is shorter than the diameter of the sphere, and the sphere is configured to roll between a first state in which it does not contact the inner circumferential surface of the opening and a second state in which it contacts the inner circumferential surface of the opening. [Effects of the Invention]

[0012] According to the sound-emitting device of the present invention, different sounds are emitted from the speaker when the first sensor detects at least one of horizontal shaking and tilt changes of an object, and when the second sensor detects vibration perpendicular to the surface on which the device is installed. For example, if the sound-emitting device is installed on an offering box, an alarm sound will be emitted when the offering box or offerings are about to be stolen, while when an offering is placed in the offering box, a sound that evokes a sense of comfort to the worshipper, such as the sound of birds chirping or the sound of dripping water, will be emitted to indicate receipt of the offering. Furthermore, the device is designed to prevent the alarm sound from being emitted unintentionally when an offering is placed in the offering box. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0014] Hereinafter, the sound emitting device according to the present invention will be described in more detail based on the drawings, but the present invention is not limited to these embodiments. In this specification, the "vertical direction", "front-rear direction", and "left-right direction" shall mean the "vertical direction", "front-rear direction", and "left-right direction" shown in each figure.

[0015] (Sound Emitting Device) FIG. 1 shows a schematic view showing an embodiment of a sound emitting device (hereinafter, may be simply referred to as "device") SG according to the present invention. The device SG shown in FIG. 1 has a rectangular parallelepiped housing C, and inside the housing C, there are a battery Ba as a power source, a switch SW for turning on and off the power supply from the battery Ba, a speaker 6, a first sensor S1, a second sensor S2, an LED (Light Emitting Diode) 7 indicating the operating state of the device SG, and a control unit (control means) 3.

[0016] Figure 2 shows a block diagram of the device SG in Figure 1. Power from the battery Ba is supplied to the control unit 3, speaker 6, and LED 7 via the switch SW. The control unit 3 has a control circuit 31, a memory 32, and a timer 33. The memory 32 stores the timer 33's setting time and input / output settings. Detection signals from the first sensor S1 and the second sensor S2 are transmitted to the control unit 3. The control unit 3 then activates the speaker 6 based on these detection signals to emit a predetermined sound. At the same time, it blinks or lights up the LED 7 to notify the outside of the change in the state of the object. The following describes each component.

[0017] (First sensor S1) The first sensor S1 used in this invention is not particularly limited as long as it can detect at least one of the horizontal shaking and tilt changes of the object on which the device SG is installed, and is not particularly good at detecting vibrations perpendicular to the surface on which the device SG is installed; conventionally known sensors can be used. For example, the first sensor S1 can be a sensor in which terminals are provided on the inner bottom surface and inner side surface of a cylindrical housing, and a conductive sphere is placed inside the housing. In the normal state, a sensor with such a structure has the sphere in contact with the terminals on the inner bottom surface and the terminals on the inner surface of the housing, and there is conductivity between the terminals, or the sphere does not contact the terminals on the inner surface and there is no conductivity between the terminals. When horizontal shaking or tilt changes occur, the sphere rolls, and the conductivity between the terminals on the inner bottom surface and the terminals on the inner surface is broken, or the sphere comes into contact with both terminals and there is conductivity between the terminals. The shaking or tilt change is detected by this change from conductivity to non-conductivity or from non-conductivity to conductivity between the terminals. Furthermore, with a sensor of such a structure, it is difficult to detect vertical vibrations.

[0018] Figure 3 shows a perspective view of one embodiment of the first sensor S1 usable in the present invention, Figure 4 shows its assembly diagram, and Figure 5 shows its vertical cross-section. The first sensor S1 shown in these figures comprises a first plate-shaped member 11 which is rectangular in plan view, a cylindrical insulating peripheral wall member 14 attached to the upper surface of the first plate-shaped member 11, a sphere 13 which is rotatably housed within the peripheral wall member 14, a second plate-shaped member 12 which is rectangular in plan view and has an opening 121 that penetrates vertically, attached to the upper end surface of the peripheral wall member 14 substantially parallel to the first plate-shaped member 11, and a substantially hemispherical cover member 15 attached to the second plate-shaped member 12 so as to seal the top of the opening 121.

[0019] (First plate-shaped member 11) The first plate-shaped member 11 is formed from a conductive metallic material. Therefore, the entire upper surface of the first plate-shaped member 11 constitutes the first conductive region. Examples of metallic materials include copper, tungsten, nickel, molybdenum, gold, silver, and alloys thereof.

[0020] In plan view, approximately in the center of the first plate-like member 11, there is a recess 111 with an inverted cone shape, whose base diameter is significantly smaller than the diameter of the sphere 13, and whose base diameter is about 1 / 20 to 1 / 10 of the diameter of the sphere 13. This recess 111 positions the sphere 13, which will be described later, in a first state. A plate-shaped terminal 112 is provided at the front left corner of the upper surface of the first plate-like member 11, projecting outward from the outer edge of the first plate-like member 11.

[0021] (Second plate-shaped member 12) The second plate-shaped member 12 has substantially the same external shape as the first plate-shaped member 11 and is made of a conductive metal material. If necessary, a vapor-deposited layer such as gold may be provided on the surface to further enhance conductivity. A circular opening 121 that penetrates vertically is provided in the approximate center of the second plate-shaped member 12 in a plan view. The inner diameter L1 (shown in Figure 5) of the opening 121 is set to be smaller than the diameter d1 of the sphere 13, which will be described later. Furthermore, since the second plate-shaped member 12 is made of a conductive metal material, the entire inner circumferential surface of the opening 121 constitutes the second conductive region. A plate-shaped terminal 122 is provided at the left rear corner of the upper surface of the second plate-shaped member 12 so as to protrude outward from the outer edge of the second plate-shaped member 12.

[0022] (Sphere 13) The sphere 13 is a steel ball with its surface coated with gold. Of course, the sphere 13 itself may be made of a conductive metal material or the like. There are no particular limitations on the diameter d1 of the sphere 13 (shown in Figure 5), and it can be appropriately determined based on the size and shape of the device using the first sensor S1, or the object to which the device is attached, as well as the magnitude and strength of the vibration to be detected, but it is generally preferable to have a diameter of about 5 mm to 50 mm. There are also no particular limitations on the density of the sphere 13, but from the viewpoint of being able to detect even the slow horizontal movement (vibration) of the object to which the first sensor S1 is attached, it is preferable that the sphere 13 has a certain amount of mass. That is, if the mass of the sphere 13 is large, when the object to which it is attached moves at a low speed in the horizontal direction, the first plate-shaped member will move, while the sphere 13 will be less likely to move due to inertial force, so as a result the state of the sphere 13 will change from the first state to the second state or from the second state to the first state, and the first sensor S1 will detect the movement of the object to which it is attached. The preferred density of sphere 13 is 4.5 g / cm³. 3 That concludes the explanation. The preferred upper limit for the density of sphere 13 is 10 g / cm³. 3 That is the case.

[0023] (Peripheral wall member 14) The peripheral wall member 14 surrounds the sphere 13 without contact with it and also serves to define the distance between the first plate-like member 11 and the second plate-like member 12. In this embodiment, the peripheral wall member 14 has a cylindrical shape and is made of an insulating material such as resin. The inner diameter D1 (shown in Figure 5) of the peripheral wall member 14 is larger than the diameter d1 (shown in Figure 5) of the sphere 13. The vertical height of the peripheral wall member 14 is set to be shorter than the diameter d1 of the sphere 13. That is, the distance H (shown in Figure 5) between the first plate-like member 11 and the second plate-like member 12 is set to be shorter than the diameter d1 of the sphere 13. Note that the shape of the peripheral wall member 14 is not limited to a cylindrical shape; any shape that can surround the sphere 13 without contact with it is acceptable.

[0024] (Lid member 15) The lid member 15 serves to cover the area above the opening 121 of the second plate-shaped member 12 without contacting the sphere 13. In this embodiment, the lid member 15 is approximately hemispherical in shape and is made of an insulating material such as resin. The shape of the lid member 15 is not limited to approximately hemispherical; any shape that can cover the area above the opening 121 without contacting the top of the sphere 13 is acceptable.

[0025] (Assembly of the first sensor S1) The first sensor S1, composed of the above components, is assembled as follows. Referring to Figure 4, first, the lower end surface of the peripheral wall member 14 is attached to the upper surface of the first plate-shaped member 11. At this time, the peripheral wall member 14 is positioned such that, in a plan view, the recess 111 of the first plate-shaped member 11 is located on the central axis of the peripheral wall member 14. The first plate-shaped member 11 and the peripheral wall member 14 can be attached using conventionally known mounting methods such as applying adhesive. Next, the sphere 13 is inserted into the interior of the peripheral wall member 14. Then, the lower surface of the second plate-shaped member 12 is attached to the upper end surface of the peripheral wall member 14. At this time, the upper part of the sphere 13 is located inside the opening 121 of the second plate-shaped member 12. The second plate-shaped member 12 and the peripheral wall member 14 can be attached using conventionally known mounting methods such as applying adhesive. Next, the lid member 15 is attached so as to cover the upper part of the opening 121 of the second plate-shaped member 12. The second plate-shaped member 12 and the lid member 15 can be attached using conventionally known attachment methods, such as applying adhesive. The lid member 15 may be attached to the second plate-shaped member 12 before the second plate-shaped member 12 is attached to the peripheral wall member 14.

[0026] In the first sensor S1 with this structure, when the normal state is horizontal, the sphere 13 is positioned in a first state where it does not contact the inner surface of the opening 121 of the second plate-shaped member 12 due to the recess 111 of the first plate-shaped member 11. At this time, there is no electrical connection between the first plate-shaped member 11 and the second plate-shaped member 12. When the first sensor S1 experiences horizontal shaking or tilt changes, the sphere 13 rolls and moves to a second state where it contacts the inner surface of the opening 121 of the second plate-shaped member 12. When the sphere 13 contacts the inner surface of the opening 121 of the second plate-shaped member 12, electrical connection becomes possible between the first plate-shaped member 11 and the second plate-shaped member 12. The first sensor S1 detects the state change from the first state to the second state as shaking. The state change to the second state may be instantaneous or continuous. Conversely, if the normal state is a tilted state, the first sensor S1 detects the state change of the sphere 13 from the second state to the first state as a change in shaking or tilt.

[0027] The detection sensitivity of the first sensor S1 can be adjusted by the distance between the inner surface of the opening 121 of the second plate-shaped member 12 and the sphere 13, and by the size of the opening 121. Specifically, if the size of the opening 121 is the same, shortening the distance H between the first plate-shaped member 11 and the second plate-shaped member 12 will shorten the distance between the inner surface of the opening 121 of the second plate-shaped member 12 and the sphere 13, thereby improving the detection sensitivity. Also, if the distance H between the first plate-shaped member 11 and the second plate-shaped member 12 is the same, reducing the inner diameter L1 (shown in Figure 5) of the opening 121 will shorten the distance between the inner surface of the opening 121 of the second plate-shaped member 12 and the sphere 13, thereby improving the detection sensitivity. In this embodiment, it is preferable that the first sensor S1 is arranged such that the first plate-shaped member 11 is substantially horizontal.

[0028] In this embodiment, the sphere 13 is housed in an airtight space composed of a first plate-shaped member 11, a second plate-shaped member 12, a peripheral wall member 14, and a lid member 15. Since the intrusion of dirt, dust, rainwater, and moisture into the airtight space is suppressed, the rolling properties of the sphere 13 and the conductivity of the conductive area are maintained well over a long period of time, and the detection sensitivity of the first sensor S1 is maintained well.

[0029] Furthermore, if the peripheral wall member 14 is not used, and the first plate-shaped member 11 and the second plate-shaped member 12 are attached, for example, with bolts and nuts so that the distance H can be adjusted, the detection sensitivity of the first sensor S1 can be adjusted by the distance H between the first plate-shaped member 11 and the second plate-shaped member 12 without replacing the members.

[0030] (Other embodiments of the first sensor S1) In the above embodiment, the entire upper surface of the first plate-shaped member 11 was designated as the first conductive region. However, the first conductive region may be formed only in the area where the sphere 13 can roll, using a conductive material. For example, a recess can be formed in the area of ​​the first plate-shaped member 11 where the sphere 13 can roll, and a conductive metal member such as copper can be attached to the recess so as to be flush with the upper surface of the first plate-shaped member 11. Alternatively, a metal such as gold can be deposited on the area of ​​the first plate-shaped member 11 where the sphere 13 can roll. In this case, the first conductive region and the terminal 112 are electrically connected by conventionally known means.

[0031] In the above embodiment, the second plate-shaped member 12 was entirely made of a conductive metal material, but the inner circumferential surface of the opening 121 of the second plate-shaped member 12 may be made of a conductive metal material such as copper, or a metal such as gold may be deposited to form a second conductive region. In this case, the second conductive region and the terminal 22 are electrically connected by conventionally known means.

[0032] (Second sensor S2) The second sensor S2 used in this invention is not particularly limited as long as it can detect vibrations of the object perpendicular to the surface on which the device SG is installed, and conventionally known sensors can be used. For example, if the object to be installed is a donation box and the device SG is installed on the inner bottom surface of the donation box, the sensor can detect the vibrations of the inner bottom surface of the donation box when donations are put in and fall and hit the inner bottom surface of the donation box.

[0033] Figure 6 shows a cross-sectional view and Figure 7 shows an assembly view of an example of a second sensor S2 that can be used in the present invention. The second sensor S2 shown in these figures comprises a pair of electrode members 21a and 21b, a cylindrical, insulating case 22 that holds the pair of electrode members 21a and 21b spaced apart and facing each other, and two conductive spheres 23a and 23b that are rotatably housed in the internal space formed by the pair of electrode members 21a and 21b and the case 22.

[0034] The pair of electrode members 21a, 21b have a frustoconical shape, with a main body portion 24a, 24b having a substantially hemispherical recess 241a, 241b on its upper surface, a disc-shaped flange portion 25a, 25b formed on the bottom side of the main body portion 24a, 24b, and a cylindrical terminal portion 26a, 26b formed on the side of the flange portion 25a, 25b opposite to the main body portion 24a, 24b, sharing the central axis with the flange portion 25a, 25b and projecting outward. The main body portion, the flange portion 25a, 25b, and the terminal portion 26a, 26b are integrally molded from a conductive material. Of course, each can also be formed from a separate conductive material and then connected.

[0035] The opening diameter D2 (shown in Figure 6) of the recesses 241a and 241b of the main body portions 24a and 24b is set to be larger than the diameter d2 (shown in Figure 6) of the spheres 23a and 23b. The inner diameter of the flange portions 25a and 25b of the electrode members 21a and 21b is set to be the same as or slightly smaller than the inner diameter of the case 22. When each of the pair of electrode members 21a and 21b is fitted into the openings at both axial ends of the case 22 with the main body portions 24a and 24b facing inward, the axial inner surfaces of the flange portions 25a and 25b abut against the axial end faces of the case 22, thereby positioning the pair of electrode members 21a and 21b in the axial and radial directions. The axial length of case 22 is set such that when the pair of electrode members 21a and 21b are attached to case 22, the maximum length L2 (shown in Figure 6) between the opposing recesses 241a and 241b is longer than twice the diameter d2 of the spheres 23a and 23b.

[0036] The two spheres 23a and 23b can be made of conductive material; for example, steel spheres with gold vapor deposition on their surface or those made of a conductive metallic material can be used.

[0037] (Assembly) As shown in Figure 7, the assembly of the second sensor S2 involves placing two spheres 23a and 23b inside the case 22, and then fitting each of the pair of electrode members 21a and 21b into the openings at both axial ends of the case 22 such that the main bodies 24a and 24b of the electrode members 21a and 21b face inward. This seals the openings at both ends of the case 22. In the assembled second sensor S2, the two spheres 23a and 23b are housed so as to be able to roll within the internal space formed by the pair of electrode members 21a and 21b and the case 22.

[0038] When the second sensor S2 is stationary, regardless of its orientation, the two spheres 23a and 23b are always in contact with the pair of electrode members 21a and 21b, so the terminals 26a and 26b of the pair of electrode members 21a and 21b are electrically conductive. On the other hand, when vibration occurs, regardless of the direction of the vibration, the spheres 23a and 23b move, and at that time the spheres 23a and 23b become non-contact, and the terminals 26a and 26b of the pair of electrode members 21a and 21b become non-conductive. As a result, even slight vibrations, such as those caused by a coin falling, can be detected by the second sensor S2.

[0039] A suitable sensor with this structure would be, for example, the MN530-02S (manufactured by G-Devices Co., Ltd.).

[0040] (Installation) From the viewpoint of enabling the detection of even slight vibrations of the object to be installed, the second sensor S2 may be installed inside the housing C on the other end of the needle-shaped member whose tip contacts the object to be installed, for example, as shown in Figure 8. Figure 8 is a partial vertical cross-sectional view when the device SG shown in Figure 10 is installed on the offering box MB's offering receiving section 82. In this figure, the second sensor S2 is fixed to the base 91 and is constantly biased downward by a compression coil spring 95. Specifically, the base 91 has a plate-shaped portion 911 and a needle-shaped portion 912 extending vertically downward from the center of the lower surface of the plate-shaped portion 911. The second sensor S2 is installed and fixed in the center of the upper surface of the plate-shaped portion 911. A through hole 99 that penetrates vertically is formed at a predetermined position in the lower wall of the housing C of the device SG. The needle-shaped portion 912 of the base 91 is inserted through the through hole 99 of the housing C and protrudes outward from the housing C. Preferably, the axial length of the needle-shaped portion 912 is set such that, when the lower surface of the plate-shaped portion 911 of the base 91 is in contact with the inner bottom surface of the housing C, the amount of the needle-shaped portion 912 protruding from the housing C is several millimeters longer than the thickness of the adhesive 90 used to attach the device SG to the inner bottom surface of the offering box 82.

[0041] A countersunk screw 92 is inserted through the upper wall of the housing C so as to protrude inward from the outside, with its central axis coaxial with that of the through hole 99, and is fixed to the upper wall of the housing C by a first nut 93. A second nut 94 is further screwed onto the threaded portion of the countersunk screw 92 so as to be movable in the axial direction. A compression coil spring 95 is externally fitted onto the threaded portion of the countersunk screw 92, with the upper end of the compression coil spring 95 in contact with the second nut 94 and the lower end of the compression coil spring 95 in contact with the case 22 of the second sensor S2 fixed to the upper surface of the base 91. As a result, the base 91 to which the second sensor S2 is fixed is always biased downward by the compression coil spring 95, i.e., in a direction in which the needle-shaped portion 912 of the base 91 protrudes outward from the housing C. The biasing force by the compression coil spring 95 can be adjusted by moving the threaded portion of the countersunk screw 92 axially with the second nut 94. The mounting of the second sensor S2 is not limited to this form; it can also be simply fixed to the housing C using conventionally known fixing members such as screws or adhesives.

[0042] (Speaker 6) The speaker 6 used in this invention is not particularly limited as long as it can produce at least two types of sound, and for example, piezoelectric, dynamic, electrostatic, ionic, and magnetic types can be used. Among these, piezoelectric speakers, whose frequency is adjusted by an oscillation circuit, are preferred due to their low power consumption and other advantages.

[0043] Speaker 6 emits, for example, when the device SG is installed on a donation box, a warning or alert sound, such as a sound to notify the theft of the donation box, when the first sensor S1 detects it, and a sound that makes the person who put money in the donation box feel comfortable or a sound of gratitude, when the second sensor S2 detects it. Examples of such sounds include the chirping of nightingales and crickets, the sound of a suikinkutsu (water harp), and voices such as "Welcome to the shrine." Furthermore, when the device SG is installed on a door, when the first sensor S1 detects that the door has opened, it emits sounds such as a buzzer or cowbell, or a voice message such as "Welcome," and when the second sensor S2 detects that the door has been knocked on, it emits sounds such as wind chimes or the sound of water, to indicate that the door has been knocked on. The sounds emitted from speaker 6 can be input from an external source and stored in memory 32. Alternatively, three or more types of sounds can be stored, and the stored sounds can be emitted in sequence each time a sensor is detected.

[0044] (Switch SW) The switch SW used in this invention preferably consists of a switch body and a key. By inserting the key into the switch body and operating the key, the power supply from the power source to each electrical component can be switched on and off. After operating the key inserted into the switch body to turn the power supply to the "on" state, when the key is removed from the switch body, the device will remain in the "on" state. In other words, the switch cannot be turned to the "off" state without the key. Furthermore, it is preferable that a dustproof shutter is provided in the keyhole to prevent water, dust, etc. from entering through the keyhole.

[0045] (Cabinet C) The housing C is not particularly limited in size or shape, as long as it can house the components constituting the present invention. From the viewpoint of making the device SG of the present invention portable, it is desirable that the housing C be small and lightweight. Plastic is preferred as the material for the housing C from the standpoint of processability and light weight. The objects on which the device SG of the present invention is installed are envisioned to be, for example, offering boxes and doors, and outdoor use is also possible, so it is preferable that the housing C be made of a material and structure that prevents water from entering the interior.

[0046] The housing C is provided with an openable and closable cover (not shown) that allows for the replacement of the battery Ba. An opening (not shown) is also provided in the housing C in the area corresponding to the switch SW and LED 7, exposing the key attachment / detachment part of the switch SW and LED 7 to the surface of the housing C. Furthermore, as shown in Figure 8, a through hole 99 is provided in the bottom wall of the housing C, allowing the tip of the needle-shaped part 912 of the base 91 to which the second sensor S2 is attached to protrude outward.

[0047] (flowchart) Figure 9 shows an example of a control flowchart for the sound-emitting device SG. When the switch SW is turned on, various initial settings are performed. Specifically, the speaker 6 is stopped, the LED 7 is turned on, and the timer 33 is cleared (step S101). After that, it is determined whether 60 seconds or more have elapsed since the timer 33 was turned on (step S102). In other words, a 60-second grace period is given from the time the switch SW is turned on until the sound-emitting device SG is installed on the desired object to be installed, such as a donation box or door. During this time, it is not determined whether the first sensor S1 and the second sensor S2 have detected shaking or vibration. Of course, this grace period can be changed by inputting a setting into the memory 32 of the control unit 3.

[0048] When 60 seconds have elapsed since the timer 33 started ("Y" in step S102), the LED 7 turns off (step S103), and the start of detection by the first sensor S1 and the second sensor S2 is announced. Specifically, it is first determined whether the first sensor S1 has detected any shaking or tilting of the object being installed (step S104). In other words, it is determined whether the first sensor S1 has changed from an on state to an off state, or from an off state to an on state.

[0049] If the state of the first sensor S1 changes ("Y" in step S104), it is assumed that some horizontal shaking or tilt change has occurred in the object being installed, so the timer 33 is cleared, the LED 7 lights up, the second sound stops being emitted, and the speaker emits the first sound (for example, an alarm sound) (step S105). Then, it is determined whether more than 10 seconds have elapsed in the timer 33 (step S106). In other words, the speaker 6 continues to emit the first sound for 10 seconds, and the LED 74 remains lit. When 10 seconds have elapsed in the timer 33 ("Y" in step S106), the timer 33 is cleared, the LED 7 turns off, and the first sound from the speaker 6 stops (step S107). Next, it is determined whether more than 3 seconds have elapsed in the timer 33 (step S108). When 3 seconds have elapsed in the timer 33, the process returns to step S104 and the state change of the first sensor S1 is determined again.

[0050] On the other hand, if the first sensor S1 has not changed state ("N" in step S104), it is then determined whether the second sensor S2 has detected anything (step S109). That is, it is determined whether vibration has occurred in the object to be installed. If the second sensor S2 has detected vibration ("Y" in step S109), the timer 33 is cleared and a second sound (for example, a bird's chirp) is emitted from the speaker 6 (step S110). Next, it is determined whether the first sensor S1 has detected anything (step S111), and whether more than 3 seconds have elapsed on the timer 33 (step S112). Once 3 seconds have elapsed on the timer 33, the process returns to step S104 and the state change of the first sensor S1 is determined again. On the other hand, if the state of the first sensor S1 changes while speaker 6 is emitting the second sound ("Y" in step S111), the process returns to step S105, timer 33 is cleared, the second sound stops being emitted, and speaker 6 emits the first sound.

[0051] The above control steps from step S104 to step S113 are repeated until the switch SW is turned off.

[0052] Furthermore, in the control of the sound-emitting device SG described above, the setting time of the timer 33 and other settings can be changed to desired values ​​by external input operations.

[0053] (Usage example 1) The sound-emitting device SG of the present invention can be installed inside an offering box and used to prevent theft. Figure 10 is a perspective view showing an example in which the sound-emitting device SG according to the present invention is installed in an offering box MB.

[0054] The offering box MB comprises a box body 81 with a top opening and a roughly rectangular shape, and an offering receiving section 82 located at the inner bottom of the box body 81, which can be inserted into and removed from the box body 81. In the top opening of the box body 81, triangular prisms 811, with their lower surfaces being horizontal and extending in the left-right direction, are provided at predetermined intervals in the front-to-back direction, with gaps that allow coins and banknotes to pass through. In addition, a storage opening 812 is provided at the lower part of the right side wall of the box body 81, through which the offering receiving section 82 can be inserted and removed. The offering receiving section 82 is a rectangular parallelepiped with a top opening, and its base area is the same as or slightly smaller than the inner bottom surface of the box body 81, and its height is the same as or slightly smaller than the height of the storage opening 812 of the box body 81. The height of the offering receiving section 82 is generally determined appropriately in the range of a few centimeters to more than ten centimeters, according to the size of the box body 81. Furthermore, when the offering box portion 82 is stored inside the box body 81 through the storage opening 812, the right side wall of the offering box portion 82 and the outer surface of the right side wall of the box body 81 are set to be flush.

[0055] A sound-emitting device SG is placed inside the offering box MB having this configuration. The sound-emitting device SG is attached, for example, to the inner bottom wall of the offering box MB with adhesive 90 (shown in Figure 8). When the switch SW of the sound-emitting device SG is turned on, the LED 7 lights up to indicate the start of control. When the control flowchart shown in Figure 10 is executed, within 60 seconds of the switch SW being turned on, the sound-emitting device SG is placed inside the offering box 82, the offering box 82 is stored inside the box body 81 through the storage opening 812, a latch 83 is provided between the box body 81 and the offering box 82, and a padlock (not shown) is attached to the ring 84. In other words, within 60 seconds of the switch SW being turned on, even if the first sensor S1 and the second sensor S2 detect shaking, the speaker 6 does not emit sound, as this is a grace period because the sound-emitting device SG is installed in its predetermined position. Of course, the grace period can be changed by setting an external input to the control unit 3.

[0056] Furthermore, when installing the sound-emitting device SG, it is desirable that the sound-emitting device SG be installed so that the upper surface of the first plate-shaped member 11 of the first sensor S1 is horizontal. That is, when the first plate-shaped member 11 is horizontal and the sphere 13 is in the first state, the first sensor S1 can detect shaking and tilt changes in all directions except the vertical direction.

[0057] The horizontal position of the first sensor S1 can be adjusted by a structure such as that shown in Figure 11. The first sensor S1 shown in Figure 11 has a shaft portion 41 that protrudes substantially perpendicularly outward from the outer circumferential surface of the peripheral wall member 14. The shaft portion 41 is inserted through a hole 43 formed in the wall of the housing C that penetrates from the outside to the inside, and a cylindrical knob 42 with a larger diameter than the shaft portion 41 is provided at the tip of the shaft portion 41 that protrudes outward. By rotating the knob 42, the first sensor S1 swings, and the horizontal position of the first sensor S1 can be adjusted.

[0058] In a donation box MB equipped with such a sound-emitting device SG, if the donation box MB is lifted or tilted, or if the donation receiving section 82 is pulled out from the box body 81, the speaker 7 of the sound-emitting device SG emits a first alarm sound for a predetermined time (10 seconds). Furthermore, unlike conventional devices, in the sound-emitting device SG, even when the donation receiving section 82 is slowly pulled out from the donation box MB while maintaining a horizontal position, the sphere 3 moves relatively due to inertial force, and the sound-emitting device SG detects the movement (shaking) of the donation receiving section 82, causing the speaker 7 to emit an alarm sound.

[0059] On the other hand, when an offering is inserted and falls into the offering box 82, the bottom wall of the offering box 82 vibrates. The second sensor S2 detects this vibration and the speaker 6 emits a second sound, which is a sound corresponding to the receipt of an offering (such as a bird's chirp). Note that the first sensor S1 has difficulty detecting vibrations in the vertical direction, so even if an offering is inserted and falls into the offering box 82, the speaker 7 is suppressed from emitting the first sound, which is an alarm sound.

[0060] (Usage example 2) The sound emitting device SG of the present invention can also be used to detect the opening and closing of a door. Figure 12 is a perspective view showing an example in which the sound emitting device SG according to the present invention is installed on a rotating door DR. The sound emitting device SG is mounted above the handle HD of the door DR. When the door DR is opened or closed, the first sensor S1 detects the movement of the door DR and the speaker 7 of the sound emitting device SG emits a first sound (for example, the sound of a cowbell). The installation position of the sound emitting device SG is not particularly limited as long as it is a position in which the first sensor S1 moves due to the opening and closing of the door DR. As mentioned above, when installing the sound emitting device SG, the knob 42 of the first sensor S1 shown in Figure 11 is rotated so that the upper surface of the first plate-shaped member 11 of the first sensor S1 becomes horizontal, thereby rotating the first sensor S1.

[0061] Furthermore, in this example of use, the tip of the needle-shaped portion 912 of the base 91 to which the second sensor S2 is attached is in contact perpendicularly with the vertical surface 50 of the door to which the device SG is attached. As a result, the second sensor S2 detects vibrations perpendicular to the vertical surface 50 of the door. In other words, when the door DR is knocked, the second sensor S2 detects the vibration of the door DR and the speaker 7 emits a second sound (for example, a bird's chirp). Furthermore, the first and second tones emitted from the sound-emitting device SG should be sounds that allow for the distinction between opening and closing the door DR or knocking on the door DR. [Industrial applicability]

[0062] According to the sound-emitting device of the present invention, different sounds are emitted from the speaker when the first sensor detects at least one of horizontal shaking and tilt changes of an object, and when the second sensor detects vibration perpendicular to the surface on which the device is installed. For example, if the sound-emitting device is installed on an offering box, an alarm sound can be emitted when the offering box or offerings are about to be stolen, and when an offering is placed in the offering box, a sound that evokes a sense of comfort to the worshipper, such as the sound of birds chirping or the sound of dripping water, can be emitted to indicate receipt of the offering.
