Description

  The present invention relates to an electronic wind chime that reproduces wind chimes in response to wind.

  Now that urbanization, housing sealing and building are progressing, we rarely hear the sound of wind chimes swaying in the natural wind we heard in our old homes.

  As a result of urbanization, houses can be crowded and the sound of wind chimes can be a nuisance to the neighborhood, and there is no room for hanging wind chimes in airtight rooms.

  The wind chime that rings in response to the conventional wind was suspended from the bell that was hung by a string with a fixed upper end, a pendulum attached to the string that penetrated the bell, and a pendulum. It consists of strips. When the strip receives wind, the pendulum is swung in conjunction with the strip, and the pendulum collides with the inside of the bell and produces a unique tone of a wind chime.

  As described above, there are now few places to hang wind chimes that receive natural winds, and attempts have been made to reproduce wind chimes using electronic circuits. For example, electronic wind chimes that randomly generate electronic sounds by imitating wind chimes, electronic wind chimes that cause a pendulum including a magnet to be electrically driven randomly through a coil, and cause the pendulum to collide with the inside of a bell have been developed.

  However, the former electronic wind chime has a problem that it generates a sense of incongruity because the generated sound is an electronic sound. Further, the latter electronic wind chimes can generate natural sounds, but they are monotonous. Even if the timing is random, they become accustomed over time and cannot reproduce the tone of a wind chime that sounds natural.

  Therefore, Patent Document 1 discloses an electronic wind chime that improves the latter electronic wind chime and generates wind chimes by changing the vibration pattern of the pendulum, thereby suppressing tiredness. The invention of Patent Document 1 can change the vibration pattern by changing four parameters of pulse width, pulse period, number of pulses, and group pulse period.

  On the other hand, in Patent Document 2, the wind chimney itself has a structure in which the pendulum collides with the inside of the bell by the wind received by the strip and sounds the wind chime. However, a wind chime that can visually appreciate the wind simultaneously with the sound is disclosed. Yes. That is, according to the invention of Patent Document 2, the overlapping portion where the pendulum collides with the bell emits light by the light emitting material on the surface of the pendulum, and thus the overlapping portion can be visually appreciated together with sound.

  However, since the wind chime of Patent Document 2 receives a wind and sounds like a conventional wind chime, it cannot be used indoors and cannot solve the problem that it is difficult to hang it. In addition, since light is emitted by the light emitting material, it is difficult to express fluctuations in wind strength.

  In addition, since the invention of Patent Document 1 does not sound by detecting vibration or wind that actually occurs, natural fluctuation cannot be expressed.

  Therefore, the present invention is a table-top wind chime device that can generate the sound of the wind chimes themselves and the light simultaneously with the wind force applied from the outside of the wind chimes, and can change the light emission intensity according to the magnitude of the wind force. I will provide a.

In FIG. 1, the support column 22 penetrates the dish portion 12 and is fixed to the housing 24 or a device in the housing 24. The sensor 16 is preferably attached inside or outside the housing 24, and the control device 18 and the operating means 20 are preferably arranged inside the housing 24. The column 22 is preferably rod-shaped, but the material is not particularly limited, and the shape and material of the housing 24 are not particularly limited.

  Further, the electronic wind chime 1 has a light emitter unit 26 attached to the column 22 in the bell member 10, and causes the light emitter unit 26 to emit light by an electrical signal output from the control device 18.

  The bell member 10 covers the luminous body unit 26 and is supported by the support column 22 above the dish part 12, and an opening 102 is formed by a lower edge 104 adjacent to the dish part 12. The range of motion of the spherical body 14 that rolls or slides on the dish portion 12 is restricted by the opening 102 formed by the edge 104.

  The shape of the bell member 10 is not particularly limited as long as the edge 104 can regulate the range of motion of the spherical body 14 and covers the light emitter unit 26 and is supported by the column 22 above the dish portion 12. As shown in FIG. 1, it may be spherical, may be an ellipsoid, a combination of a polygonal column and a polygonal pyramid, or any other shape. The bell member 10 may be fixed to the upper portion of the support 22, may be attached to be rotatable about the support 22, and may be supported to be swingable with the upper end of the support 22 as a fulcrum.

  The spherical body 14 is preferably a sphere, but its shape is not particularly limited as long as it can roll or slide on the dish portion 12.

  The bell member 10 and the spherical member 14 are formed of a material that can generate a wind chime tone when the spherical member 14 collides with the edge 104 of the bell member 10. The edge 104 of the bell member 10 is preferably provided with projections randomly on the surface so that the spherical body 14 can easily collide and generate sound.

  The bell member 10 may be formed of a material that transmits light, or may be formed of a material such as pottery that does not transmit light and provided with a hole for transmitting light. Accordingly, the bell member 10 and the spherical body 14 can be formed of, for example, glass or earthenware. However, as long as it is a material that generates a wind chime tone at the time of a collision as described above, it is not particularly selected according to an embodiment described later. The material is not limited.

  The dish part 12 is preferably formed of a material that generates as little sound as possible when the spherical body 14 rolls or slides on the dish part 12. The dish portion 12 may be fixed to the casing 24 through the support 22, or may be attached to the operating means 20 so as to be swingable or rotatable with respect to the casing 24. Further, the shape of the dish portion 12 is not particularly limited as long as the movement range of the spherical body 14 can be limited within the opening 102 of the bell member 10, but it is a gentle wave shape so that the spherical body 14 rolls in various directions.

The lamp cover 264 may be omitted.

  Next, the configuration and operation of the sensor 16 and the control device 18 that outputs an electrical signal corresponding to the output of the sensor 16 will be described.

  In FIG. 3, the control device 18 of the electronic wind chime 1 of the present invention detects the strength of the wind and outputs an electric signal corresponding to the detected wind strength, and the signal controlled by the control device 18 is input. Connected to the operating means 20 and the light emitter unit 26.

  As shown in FIG. 3, the control device 18 is connected to the power source 182, the signal processing unit 184 that oscillates the pulse while modulating the pulse width according to the electrical signal output from the sensor 16, and the power source 182 and the signal processing unit 184. And a switch circuit 186 that switches the power supply voltage in response to the pulse signal generated by the signal processing unit 184 in response to the current input from the power supply 182.

  The power source 182 uses a DC power source such as a battery. However, when an AC voltage is supplied from the outside, the power source 182 may be converted to DC by a smoothing rectifier circuit.

  As the sensor 16, for example, a condenser microphone is used. The sensor 16 is fixed inside or outside the housing 24, detects vibrations transmitted through the housing 24 due to wind or contact, or vibrations caused by direct wind, and converts them into electrical signals.

  In the sensor 16, two electrodes face each other, the distance between the two electrodes changes due to vibration, and the capacitance between the electrodes changes. Due to this capacitance change, an electrical signal such as a voltage is output from the sensor 16 to the signal processing unit 184 of the control device 18 with fluctuation caused by vibrations such as wind.

  The electrical signal output from the sensor 16 may be amplified by an amplifier in the sensor 16 and output. Alternatively, the sensor 16 may include a filter circuit that cuts signals other than wind output from the sensor 16. Since the vibration frequency of the sensor 16 due to the wind is several Hz to several tens Hz, for example, a bandpass filter can be configured by a circuit combining an operational amplifier, a resistor, and a capacitor, and signals other than the vibration frequency due to the wind can be cut. .

  The signal processing unit 184 performs PWM (Pulse Width Modulation) control on the signal received from the amplifier circuit 16. That is, the signal processing unit 184 AD-converts the signal from the sensor 16 and controls the pulse width according to the converted data. Alternatively, the signal processing unit 184 may be provided with a chaos circuit in order to generate such a fluctuation signal.

  The PWM control signal pulsed by the signal processing unit 184 is output to the switch circuit 186 via a drive circuit (not shown). The switch circuit 186 forms a step-down chopper with, for example, an FET and a diode, and controls the switch circuit 186 on / off.

  The switch circuit 186 may include a smoothing filter that smoothes the current input to the switch circuit 186. The smoothing filter 24 includes a capacitor C and a coil L, and smoothes the current. In this case, the smoothing filter smoothes the current flowing out from the switch circuit 186 when the switch circuit 186 is on, and outputs it to the operating means 20 and the light emitter unit 26. An inverter may be provided between the switch circuit 186, the operating means 20, and the light emitter unit 26 as necessary to convert a direct current into an alternating current.

  As described above, the signal detected by the sensor 16 for vibrations such as wind is output to the operating means 20 and the light emitter unit 26 as a fluctuating electric signal, and operates according to the fluctuation of the electric signal. Emits light that fluctuates.

  The operation principle for reproducing fluctuations caused by wind in the sensor 16 and the control device 18 of the electronic wind chime 1 according to the present invention having the above-described configuration will be summarized below.

1) The vibration caused by wind or the like is detected, and the electrode plate included in the sensor 16 vibrates.
2) The sensor 16 converts the vibration of the electrode plate into an electric signal, and the electric signal is amplified by an amplifier circuit provided in the sensor 16.
3) The signal processing unit 184 converts the electrical signal amplified by the amplifier circuit into a digital signal.
4) The signal processing unit 184 changes the pulse width for a certain period when the digital signal exceeds a certain threshold.
5) The switch circuit 186 and the smoothing filter 24 control the voltage applied to the operating means 20 and the light emitter unit 26 according to the fluctuation of the pulse width.
6) Due to the voltage fluctuation, the operating means 20 and the light emitter unit 26 reproduce the fluctuation detected by the electrode plate of the sensor 16.

  Note that the sensor 16 and the control device 18 of the present invention may be configured using other various electric / electronic components as long as the circuit performs the same operation as the circuit block shown in FIG.

  Hereinafter, the operation of the electronic wind chime which sounds by detecting the wind according to the present invention will be described separately in the embodiment of the operation means 20.

  The operation means 20 of the first embodiment is a linear motor system.

  FIG. 4A is a cross-sectional view schematically showing an electronic wind chime 1001 employing a linear motor system. In this embodiment, the operating means 20 includes an operating power source 202 to which an electric signal fluctuating from the switch circuit 186 is input, and a plurality of coils 204 through which an alternating current supplied from the operating power source 202 flows.

  As shown in FIG. 4B, the plurality of coils 204 are arranged in a circle with respect to the center of the dish portion 122. As shown in FIG. 4A, for example, the plurality of coils 204 are perpendicularly opposed to the dish portion 122, and adjacent coils 204 are alternately wound in opposite directions. Hereinafter, for convenience, it is assumed that the plurality of coils 204 are composed of n (n ≧ 2; natural number) linear coils.

  The plate portion 122 disposed above the plurality of coils 204 is fixed to the housing 24 and preferably has a flat plate shape that gently swells. The dish part 122 is formed of a non-magnetic material such as plastic, and the spherical body 14 is formed including a magnetic material.

  The operating means 20 includes a driving linear coil selection circuit that selects the k-th (1 ≦ k ≦ n) linear coil k among the plurality of coils 204. Here, since the linear coils are arranged in a circular shape, the linear coil n + 1 designates the linear coil 1.

  When an electric signal is input from the switch circuit 186 to the operating power source 202, the driving linear coil selection circuit sequentially selects the linear coils k in the circumferential direction, and sequentially supplies the fluctuating current flowing in the same direction in each linear coil. .

FIG. 6A shows the state of current flowing through each linear coil. In FIG. 6A, symbols such as k and k + 1 indicate linear coil numbers, the horizontal axis indicates time, and the vertical axis indicates current. I _max is the magnitude of the current when the gravity acting on the spherical body 14 and the magnetic force generated by flowing current through the linear coil balance when the magnetic force of the spherical body 14 and the linear coil repels.

  As described above, in the present embodiment, the adjacent linear coil k and linear coil k + 1 are wound in opposite directions, so that when a current in the same direction flows, the plurality of coils 204 are sequentially excited in opposite directions. Is done. For this reason, the magnetized spherical body 14 is attracted to the linear coil k through which current flows one after another, and rotates in the circumferential direction of the dish portion 122.

  Alternatively, the adjacent linear coil k and linear coil k + 1 may be wound in the same direction. In this case, as shown in FIG. 6B, the spherical body 14 can be similarly rotated in the circumferential direction of the dish portion 122 by sequentially passing a current through the adjacent linear coils in the reverse direction.

As described above, when the drive linear coil selection circuit continues to apply the current I to the linear coil in order, the spherical body 14 moves circularly, and is eventually blown outward by centrifugal force and collides with the edge 104 of the bell member 10. Generate wind chimes. Alternatively, it collides with the edge 104 by colliding with a protrusion randomly provided on the surface of the edge 104, changing the direction according to the surface shape of the dish portion 122, and floating on a linear coil through which a current larger than I _max flows. .

  As described above, the electronic wind chime 1001 can reproduce the fluctuation detected by the sensor 16 together with the light emission of the light emitter unit 26 to generate the tone of the wind chimes.

  In the present embodiment, the drive linear coil selection circuit selects the linear coils k one by one in the circumferential direction in order in the linear coil, but a plurality of linear coils may be selected simultaneously. Two or more adjacent linear coils may be selected at the same time, a plurality of linear coils wound in the same direction may be selected at the same time, and the linear coils can be selected by various other methods.

  In the electronic wind chime 1001, the plurality of coils 204 are arranged in a circle perpendicular to the dish portion 122, but the plurality of coils 204 may be arranged in a circle on the side of the dish portion 122 as shown in FIG. 5. . Other configurations of the electronic wind chime 2001 of the second embodiment are the same as those of the electronic wind chime 1001.

  The operating means 20 selects linear coils in order in the circumferential direction, as in the above embodiment. 6A or 6B, an electric signal output from the control device 18 is supplied to the linear coil as shown in FIG. 6A or 6B, and the spherical body 14 makes a circular motion by sequentially exciting it in the opposite direction to the edge 104 of the bell member 10. Collisions generate wind chimes.

  Or the magnitude | size of the electric current sent through a linear coil may be constant. For example, it is assumed that adjacent linear coils 204 are all wound in the same direction toward the center of the plate portion 122. In order to sequentially excite the linear coil 204 in the reverse direction, it is only necessary to pass a current in the reverse direction sequentially to the adjacent linear coils as shown in FIG. Also in this case, the spherical body 14 makes a circular motion, and can collide with the edge 104 of the bell member 10 to generate a wind chime.

  In the electronic wind chime 2001, the plurality of coils 204 are arranged in a circular shape on the side of the dish portion 122, but the number of the plurality of coils 204 may be two. As shown in the sectional view of FIG. 5, linear coils may be arranged to face each other.

  Currents that fluctuate in both coils are alternately or simultaneously applied to generate a magnetic field that fluctuates left and right. The spherical body 14 moves substantially left and right under the force of this magnetic field, and generates a wind chirp when it collides with the edge 104 of the bell member 10.

  In the above embodiment, the operating means 20 moves the spherical body 14 using electromagnetic force, but the operating means 20 may include mechanical means. In the following embodiment, the spherical body 14 is a non-magnetic body.

  For example, the operating means 20 of the third embodiment is a vibrator system, and a schematic cross-sectional view of an electronic wind chime 3001 using this system is shown in FIG.

In the present embodiment, the operating means 20 is supplied from the operating power supply 202, a cylinder disposed vertically below the tray portion 128, an operating power source 202 to which an electric signal fluctuating from the switch circuit 186 is input. And a coil 210 wound around the cylinder 212 and a magnetic vibrator 214 that is restrained in the cylinder 212 and vibrates up and down.
The magnetic vibrator 214 may be attached to the housing 24 by a spring in the cylinder 212.

  The dish portion 128 uses an elastic film made of an elastic body such as rubber, but the material is not limited to rubber as long as it is a thin film having elasticity. The end of the dish 128 is fixed by the opening end of the housing 24 or the like.

  When an alternating current supplied from the operating power supply 202 flows to the coil 210, the vibrator 214 vibrates up and down in the cylinder 212 due to the magnetic field generated by the coil 210. When the vibrator 214 collides with the elastic film dish 128, the dish 128 vibrates, and the spherical body 14 moves on the dish 128. When the spherical body 14 collides with the edge 104 of the bell member 10, a wind chime is generated, and the fluctuation detected by the sensor 16 can be reproduced in the same manner as the electronic wind chime of the above embodiment.

  The operation means 20 of the fourth embodiment is a dish rotation system.

  FIG. 9A is a cross-sectional view schematically showing an electronic wind chime 4001 that employs a pan rotation method. In the present embodiment, the operating means 20 includes an operating power supply 202 to which an electric signal fluctuating from the switch circuit 186 is input, and a motor 216 that operates by obtaining power from the operating power supply 202.

  In the present embodiment, the dish portion 12 has a central portion that is lower than the peripheral portion, and has a hollow shape in which a central portion is provided with a cylindrical portion through which the support column 22 passes.

  The motor 216 may be directly connected to the cylindrical portion of the dish portion 12 by rubber or the like when using a motor with a small rotational speed such as an ultrasonic motor. However, if the rotational speed is too large, the speed reduction means 218 is used. To the cylindrical portion.

  In the present embodiment, the speed reducing means 218 is configured by three gears 218a, 218b, and 218c having different radii as shown in FIG. 9B, for example. From 218a to 218c, the number of teeth at equal intervals is increased, and the rotation of the motor 216 is decelerated. The gears 218a, 218b, and 218c may have a structure in which rubber having a large friction coefficient is attached to the shaft.

  When the motor 216 is rotated by the electric power supplied from the operation power source 202, the dish part 12 is rotated directly or via the speed reduction means 218, and the spherical body 14 moves on the dish part 128. When the spherical body 14 collides with the edge 104 of the bell member 10 due to the centrifugal force generated by the rotation of the plate part 12, a wind chime sound is generated, and the fluctuation detected by the sensor 16 is reproduced in the same manner as the electronic wind chime of the above embodiment. Can do.

  The operation means 20 of the fifth embodiment is a pachinko system.

  FIG. 10A is a cross-sectional view schematically showing an electronic wind chime 5001 employing a pachinko method. In this embodiment, the operating means 20 includes an operating power supply 202 to which an electric signal fluctuating from the switch circuit 186 is input, a coil 222 through which an alternating current supplied from the operating power supply 202 flows, and an oscillating means 220.

  Here, the swinging means 220 includes a striking portion that strikes the spherical body 14 on the plate portion 12, an action portion formed of a magnetic material, and a shaft portion that penetrates the plate portion 12 and connects the striking portion and the action portion. It consists of. As shown in FIG. 10B, which is a plan view of the casing 24 in which the swinging means 220 is installed, the coil 222 is disposed so as to be substantially perpendicular to the plate-like action portion of the swinging means 220 when stationary. . Further, the swinging means 220 is rotatable about the shaft portion, and the action portion may be connected to the housing 24 by a spring in order to limit the rotation range.

  The shape of the dish part 12 is preferably a water-like shape like the dish part 12 of the fourth embodiment, and is fixed to the housing 24. The shaft part of the swinging means 220 passes through a cylindrical part provided at the center of the dish part 12 and connects the striking part and the action part. The striking part of the swinging means 220 is arranged so as to be close to but not in contact with the dish part 12.

  When an alternating current supplied from the operating power supply 202 flows to the coil 222, the magnetic material acting part of the oscillating means 220 receives a force by the magnetic field generated by the coil 222, and the oscillating means 220 rotates about the shaft portion. . When the striking portion of the swinging means 220 comes into contact with the spherical body 14, the spherical body 14 moves on the dish portion 12. When the spherical body 14 collides with the edge 104 of the bell member 10, a wind chime is generated, and the fluctuation detected by the sensor 16 can be reproduced in the same manner as the electronic wind chime of the above embodiment.

  The operation means 20 of the sixth embodiment is a cam system.

  FIG. 11A is a cross-sectional view schematically showing a part of the plate portion 130 and the operating means 20 of the electronic wind chime 6001 adopting the cam method. In the present embodiment, the operating means 20 is linked to the operating power source 202 to which an electric signal fluctuating from the switch circuit 186 is input, the two motors 225 and 227 supplied with power from the operating power source 202, and the motors 225 and 227, respectively. Rotors 224 and 226 are included.

  As shown in FIG. 11A, the plate part 130 is configured by overlapping a disk A and a disk B. The disk A is driven in one direction by the motor 225 and the rotor 224, and the disk B is rotated in the other direction by the motor 227 and the rotor 226. The disk B is fixed in the vertical direction, but the disk A can move up and down, and the spherical body 14 moves on the disk A.

  The disc A and the disc B are not flat disc shapes, but are each shaped to wave smoothly. As shown in FIG. 11B, when the rotor 224 rotates, the rotor 224 is hooked on a hook 228 provided on the inner diameter of the disk A, and rotates the disk A.

  Since the disc A and the disc B each have a smoothly undulating shape, the disc A rotates so as to vibrate up and down randomly when both rotate in opposite directions. For this reason, when power is supplied from the operating power source 202, the spherical body 14 moves on the disk A, and when it collides with the edge 104 of the bell member 10, a wind chime can be sounded.

  As mentioned above, although the embodiment of the electronic wind chime which sounds and sounds according to this invention was described, the electronic wind chime of this invention is not limited to these embodiments. For example, a switch may be installed in the housing so that the light emitter unit can be switched ON / OFF. Alternatively, the light emitting unit may be used as ordinary illumination that does not fluctuate in the wind by switching the switch. In addition, a chaos circuit for generating a fluctuation signal may be provided in the signal processing unit so that the sensor can be selected from sensors that detect fluctuations such as wind.

  Further, the plate portion may be provided with one or a plurality of protrusions on the surface to limit the movement of the spherical body. Alternatively, the protrusion may be formed so as to play a sound when colliding with the spherical body, or may be formed so as to emit a fluorescent color.

  In addition, the method for supporting the bell member can be variously selected depending on the arrangement of sensors, control devices, and the like housed in the housing and the embodiment of the operating means. The bell member may be supported by a support as shown in FIG. 1, the bell member may be hung from the housing as shown in FIG. 2, or the bell member can be supported by various other means.

  In addition, the present invention can be implemented in a mode in which various improvements, modifications, and changes are added based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
