Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the embodiments and the drawings, the same reference numerals are given to the components having substantially the same functional configurations, and overlapping descriptions are omitted.

An operation device 100 according to an embodiment will be described with reference to fig. 1 to 7. The operation device 100 is a device that outputs information according to an operation by an operator, and is mounted on any device such as an audio device or a display device.

First, the configuration of the operation device 100 will be described. Fig. 1 is a perspective view showing an example of the operation device 100. Fig. 2 is an exploded perspective view of the operating device 100 of fig. 1. Hereinafter, for convenience, the upper, lower, left, and right in the drawings will be described as the upper, lower, left, and right of the operation device 100. As shown in fig. 1 and 2, the operation device 100 includes an operated member 1, a holding member 2, a vibration generating member 3, a rotation detecting member 4, a bezel 5, a side plate member 6, a substrate 7, a control member 8, and a bottom plate member 9.

The operated member 1 is a disk-shaped member that is rotated by an operator. The operated member 1 has a rounded portion 11 on the entire periphery of the upper surface. The operator inputs desired information by performing a rotational operation while the operated member 1 is pressed toward the holding member 2. The operation device 100 outputs the inputted information. The operated member 1 is rotatably held by the holding member 2. In the example of fig. 2, the operated member 1 is not provided with an axial portion and is placed on the holding member 2. However, the operated member 1 may be provided with a shaft portion and the shaft portion may be rotatably supported by the holding member 2. In either case, the operated member 1 is held by the holding member 2 such that the lower surface of the operated member 1 is in contact with the upper surface of the holding member 2 when the operator performs an operation (when pressing toward the holding member 2).

The holding member 2 is a member that holds the operated member 1 to be rotatable. The holding member 2 includes a vibration transmission member 21 and a support member 22.

The vibration transmission member 21 is a plate-like member that holds the operated member 1, and is fixed by the support member 22. The vibration transmission member 21 is in contact with the operated member 1, and transmits the vibration generated by the vibration generating member 3 to the operated member 1. The vibration transmission member 21 includes a recess 23 and an input member 24.

The recess 23 is a circular recess formed in the upper surface of the vibration transmission member 21. The operated member 1 is held in a state of being rotatably fitted in the recess 23. When the operated member 1 is operated, the upper surface of the recess 23 is in contact with the lower surface of the operated member 1. Preferably, a viscous material such as viscous grease is applied between the recess 23 and the operated member 1. This can suppress wear between the member 1 to be operated and the concave portion 23 when the member 1 to be operated is rotated, and can generate an appropriate load. Further, the recess 23 holds the viscous material inside and prevents the viscous material from flowing out to the outside, and therefore durability against the rotational operation of the operated member 1 is improved.

The input member 24 is a member prepared separately from the operated member 1 and used for an operator to input information. In the example of fig. 2, the input member 24 is a touch button, and includes: icons provided in a manner to be observable from the surface of the vibration transmission member 21; and a touch sensor (not shown) disposed below the icon and connected to the control means 8. When the operator touches the icon portion of the vibration transmission member 21, the touch sensor detects the touch and notifies the control member 8 of the fact. This enables the operator to input information corresponding to the icon. In the example of fig. 2, the vibration transmission member 21 includes two input members 24, but may include one or three or more input members 24. The input member 24 is not limited to a touch button, and may be a hardware button, a rotary switch, or the like. The vibration transmission member 21 may be provided with a touch sensor and a liquid crystal display device, and may display any icon.

The support member 22 is a plate-like member that supports the vibration transmission member 21. As described later, the support member 22 is vibrated with respect to the side plate member 6 by the vibration generating member 3. Preferably, the support member 22 is formed of a light-weight and highly rigid resin such as pbt (polybutylene terephthalate) so that vibration can be easily performed by the vibration generating member 3. The support member 22 has a top plate portion 25 and a leg portion 26.

The top plate portion 25 is a plate-like or frame-like portion to which the vibration transmission member 21 is fixed, and is formed to be one turn larger than the vibration transmission member 21. Here, fig. 3 is a plan view of the operation device 100 of fig. 1. In the example of fig. 3, the operated member 1, the vibration transmission member 21, and the bezel 5 are removed from the operation device 100. As shown in fig. 3, the top plate 25 is disposed so that the outer peripheral portion thereof faces the inner peripheral portion of the side plate member 6. A gap 27 is formed between the outer peripheral portion of the top plate portion 25 and the inner peripheral portion of the side plate member 6 so that the top plate portion 25 can vibrate with respect to the side plate member 6. A fixing member 34 is fixed to the lower surface of the top plate 25. The fixing member 34 will be described later.

Elastic members

28 and 29 are provided on the outer periphery of the top plate 25.

The elastic member 28 is an elastic member provided on a side surface of the outer peripheral portion of the top plate portion 25. The collision of the top plate portion 25 with the side plate member 6 is suppressed by the elastic member 28. The elastic member 29 is an elastic member provided on the upper surface of the outer peripheral portion of the top plate 25. The elastic member 29 suppresses collision of the top plate 25 with the bezel 5. The elastic member may be provided on the lower surface of the outer peripheral portion of the top plate portion 25. In the example of fig. 3, a plurality of elastic members 28 are provided on each side of the top plate 25, but one elastic member may be provided on each side of the top plate 25, or may be provided over the entire length of each side. The same is true for the elastic member 29.

As shown in fig. 2, the leg 26 extends downward from the lower surface of the top plate 25. By providing the leg portion 26, the center of gravity of the support member 22 can be lowered, and the support member 22 can be stabilized. In the example of fig. 2, the support member 22 has a plurality of leg portions 2, but may have one leg portion 26 or may not have a leg portion 26. In the example of fig. 2, the vibration transmission member 21 and the support member 22 are prepared separately, but may be integrally formed.

The vibration generating member 3 is a member that vibrates the holding member 2 with respect to the side plate member 6. The vibration generating means 3 is connected to the control means 8 and controlled by the control means 8. In the example of fig. 2, the vibration generating member 3 is an actuator, but may be any member that generates vibration. Here, fig. 4 is a side view of the vibration generating member 3. Fig. 5 is a plan view of the operation device 100. In the example of fig. 5, the operated member 1 and the holding member 2 are removed from the operating device 100. As shown in fig. 4, the vibration generating member 3 includes a coil 31, a magnetic plate 32, and fixing

members

33 and 34.

The coil 31 generates a magnetic force corresponding to the current supplied from the control member 8.

The magnetic plate 32 is a plate-shaped member formed of a magnetic material. The magnetic plate 32 is, for example, an iron plate, but is not limited thereto. The magnetic plate 32 is disposed to face the coil 31.

As shown in fig. 5, the fixing member 33 is a member for fixing the coil 31 to the middle plate portion 62 of the side plate member 6. The description will be made later with respect to the middle plate portion 62. The fixing member 34 is a member for fixing the magnetic plate 32 to the lower surface of the top plate 25. The fixing

members

33, 34 fix the coil 31 and the magnetic plate 32 so that a gap 35 is formed between the coil 31 and the magnetic plate 32.

With such a configuration, when the control member 8 energizes the coil 31, the coil 31 generates a magnetic force, and the magnetic plate 32 is attracted by the coil 31 due to the magnetic force, and the top plate portion 25 (holding member 2) fixed to the magnetic plate 32 moves in a direction in which the magnetic plate 32 approaches the coil 31. When the control member 8 stops the energization of the coil 31, the magnetic force of the coil 31 disappears, and the magnetic plate 32 attracted by the magnetic force is separated from the coil 31, and the top plate portion 25 (holding member 2) fixed to the magnetic plate 32 is moved in the direction in which the magnetic plate 32 is separated from the coil 31. Therefore, the control member 8 can vibrate the holding member 2 by repeatedly switching ON and OFF the energization of the coil 31. The control means 8 can control the intensity and frequency of the vibration of the holding member 2 by controlling the magnitude and frequency of the current supplied to the coil 31.

The rotation detecting means 4 is a sensor for detecting the rotation of the operated member 1, and is connected to the control means 8. The rotation detecting member 4 may be any sensor such as a rotary encoder that can detect the rotation of the operated member 1. As the rotation detecting member 4, an optical, electromagnetic, or capacitance type sensor can be used. In the example of fig. 2, the rotation detecting member 4 is provided on the upper surface of the recess 23, but may be disposed at any position capable of detecting the rotation of the operated member 1.

The frame 5 is a frame covering the upper part of the outer periphery of the top plate 25, and is fixed to the upper surface of the side plate member 6 by a plurality of screws 51. As described above, the elastic member 29 is provided between the bezel 5 and the outer periphery of the top plate 25. Since the bezel 5 covers the upper side of the top plate 25, the support member 22 can be prevented from coming off. Here, fig. 6 is a plan view of the operation device 100. As shown in fig. 6, the frame 5 is disposed such that its inner circumferential portion faces the outer circumferential portion of the vibration transmission member 21. A gap 52 is formed between the inner peripheral portion of the bezel 5 and the outer peripheral portion of the vibration transmission member 21 so that the vibration transmission member 21 can vibrate with respect to the side plate member 6.

The side plate member 6 is a member constituting a housing of the operation device 100. As shown in fig. 2, the side plate member 6 has a side plate portion 61 and a middle plate portion 62. The side plate portion 61 is a portion constituting a housing side surface of the operation device 100. As described above, the frame 5 is fixed to the upper surface of the side plate portion 61. The middle plate 62 is a plate-shaped portion that is provided inside the side plate 61 and perpendicular to the side plate 61. The fixing member 33 of the vibration generating member 3 is fixed to the middle plate portion 62. As shown in fig. 5, the middle plate portion 62 has through holes 63 through which the legs 26 are inserted at positions corresponding to the legs 26.

The substrate 7 is a printed substrate, on which printed wiring (not shown) is formed, and is fixed to the upper surface of the bottom plate member 9. Various electronic circuits including a control member 8 are provided on the upper surface of the substrate 7. The substrate 7 may be fixed to the side plate member 6.

The control member 8 is a circuit for controlling the vibration generating member 3 in accordance with the rotation operation of the operated member 1 and the touch operation of the input member 24 by the operator, and is connected to the rotation detecting member 4, the input member 24, and the vibration generating member 3 (coil 31). The control means 8 includes a CPU (Central Processing Unit), a RAM (random Access memory) and a ROM (read Only memory). The control of the vibration generating member 3 is realized by the CPU executing a program stored in the ROM on the RAM. In the example of fig. 2, the control means 8 is one IC (integrated circuit), but may also be a plurality of ICs.

The bottom plate member 9 is a member constituting the bottom surface of the housing of the operation device 100. The bottom plate member 9 is fixed to the side plate member 6. Further, a substrate 7 is fixed to the upper surface of the bottom plate member 9. In the example of fig. 2, the side plate member 6 and the bottom plate member 9 are prepared separately, but may be formed integrally.

Next, the operation of the operation device 100 will be described. Fig. 7 is a flowchart illustrating an example of the operation device 100. Hereinafter, the rotation detecting means 4 is a means for always detecting the rotation of the operated member 1.

First, the operator presses the operated member 1 toward the holding member 2 (step S101). As in the example of fig. 2, when the operated member 1 is placed on the holding member 2, the operator presses the operated member 1 toward the holding member 2 by pinching the rounded portion 11 of the operated member 1 with a fingertip or by pressing a fingertip against the upper surface of the operated member 1. Thereby, the lower surface of the operated member 1 reliably comes into contact with the upper surface of the holding member 2.

Next, the operator rotates the operated member 1 in a desired direction while keeping the operated member pressed toward the holding member 2 (step S102). When the operated member 1 rotates, the rotation (angle) of the operated member 1 is detected by the rotation detecting means 4 and is input to the control means 8.

The control means 8 determines whether or not the operated member 1 is rotated by a predetermined angle based on the angle of the operated member 1 input from the rotation detecting means 4 (step S103). The predetermined angle may be set arbitrarily.

When the operated member 1 is detected to have rotated by the predetermined angle (step S103), the control member 8 vibrates the vibration generating member 3 (step S104). As described above, when the vibration generating member 3 vibrates, the holding member 2 vibrates with respect to the side plate member 6, and the vibration is transmitted to the operated member 1 which is in contact with the holding member 2 in a state of being pressed toward the holding member 2, so that the operated member 1 vibrates. As a result, the vibration of the operated member 1 is given to the operator as an operation feeling when the operated member 1 is rotated by a predetermined angle.

Preferably, the control member 8 vibrates the holding member 2 when the operator touches the input member 24. This can provide an operator touching the input member 24 (holding member 2) with a feeling of operation.

The operation feeling given to the operator (the vibration of the operated member 1 and the holding member 2) may be the same or different for each operation by the operator. For example, it is conceivable to make the operation feeling given when the operator performs a rotational operation on the operated member 1 different from the operation feeling given when the operator performs a touch operation on the input member 24. The control means 8 controls the magnitude and frequency of the current supplied to the coil 31, thereby changing the intensity and frequency of the vibration of the operated member 1 and the holding member 2, and giving various operation feelings to the operator.

As described above, in the operation device 100 of the present embodiment, the holding member 2 is vibrated by the vibration generating member 3, so that the operated member 1 is indirectly vibrated, and the operator can be given a feeling of operation of the operated member 1. As described above, according to the present embodiment, since it is not necessary to couple the operated member 1 and the vibration generating member 3, the configuration of the operation device 100 can be simplified. As a result, the parts and manufacturing processes of the operation device 100 can be reduced, and the manufacturing cost can be reduced.

The present invention is not limited to the configurations shown here, such as the configurations described in the above embodiments, or combinations with other elements. These aspects can be modified within a range not departing from the gist of the present invention, and can be appropriately determined according to the application form thereof.
