- Such an actuator 220 can be used, for example, by attaching the Z2 side surface of the fixed yoke 110 to the bottom plate 211 of the housing 260. By vibrating the actuator 220 in the Z1-Z2 direction as described above, the housing 260 vibrates in the Z1-Z2 direction, and the diaphragm 240 vibrates in the Z1-Z2 direction accordingly. Sound is generated by vibrating the air.

- 13A, 13B, and 13C are diagrams for explaining a non-contact state, a close contact state, and a contact state, respectively.
- 13A, 13B, and 13C show a non-contact state, a close contact state, and a contact state, respectively.
- the non-contact state is a state in which the seated person 1 (human body) is not in contact with the surface of the seat 11 (seat cloth 11C).
- the capacitance value when no one is seated on the seat 11 is smaller than that when the human body is approaching the seat 11 and when there is a seated person on the seat 11.
- the close contact state is a state in which the body of the seated person 1 is pressed against the seat 11. More specifically, the seat 11 is in a state of elastic deformation in which the seat 11 is in close contact with the seat 11 to the extent that the vibration generated by the vibration generator 200 is transmitted to the seat. If the user is seated on the seat 11, it is considered that the human body is in close contact with the diaphragm 240 of the vibration generator 200B of the seat portion 11B. Further, in the vibration generator 200A of the backrest portion 11A, the capacitance of the diaphragm 240 differs between the state in which the human body leans against the backrest portion 11A and the state in which the back is lifted.
- the distance D1 is an example of the first distance, and is the distance from the surface of the diaphragm 240 to the surface of the seat 11 in a state where no one is seated as shown in FIG. 13A.
- the distance D2 is an example of the second distance, and is shorter than the distance D1.
- the distance D2 is the distance from the surface of the diaphragm 240 to the surface of the seat 11 when there is a seated person on the seat 11. In the close contact state, the distance between the surface of the sheet 11 and the diaphragm 240 is shorter than the distance in the non-contact state, and as shown in FIG.
- the human body is in contact with the surface of the sheet 11 but is not in close contact (contact). State) shorter than. Therefore, the capacitance of the diaphragm 240 in the close contact state is larger than the capacitance in the non-contact state and the contact state.
- the determination unit 321 may determine that the diaphragm 240 is in close contact if the capacitance of the diaphragm 240 is equal to or higher than the threshold value TH2 indicating the close contact state.
- the contact state is a state in which the human body is in contact with the surface of the sheet 11 but is not in close contact with the surface as shown in FIG. 13C.
- the distance D between the surface of the sheet 11 and the surface of the diaphragm 240 in the contact state is longer than D2. Therefore, if the capacitance of the diaphragm 240 is larger than the threshold value TH1 of the capacitance and less than the threshold value TH2 when a predetermined notification condition is satisfied, the determination unit 321 determines that it is in a contact state. good.
- the determination of the close contact state and the contact state is not limited to the form of determination based on the capacitance of the diaphragm 240, but is based on the value calculated from the pressure by the pressure sensor and the elastic modulus of the backrest portion 11A.
- the determination may be made, or another sensor may be used.
- 14A to 14C are diagrams illustrating the generation of vibration or sound by the vibration generator 200.
- 14A, 14B, and 14C show the driving states of the vibration generator 200 in the non-contact state, the close contact state, and the contact state, respectively.
- the control unit 322 in the non-contact state, the control unit 322 generates a sound with a weak output level in the vibration generator 200.
- vibration cannot be transmitted to the user, the human body is not in contact with the surface of the sheet 11, and the diaphragm 240 is not covered by the human body, so that the output level is weak. This is because information can be transmitted with.
- the control unit 322 in the close contact state, the control unit 322 generates vibration in the vibration generator 200. This is because the human body is in close contact with the surface of the sheet 11 in the close contact state, so that information can be transmitted by vibration.
- the control unit 322 in the contact state, the control unit 322 generates a sound (loud sound) with a strong output level in the vibration generator 200.
- the human body In the contact state, the human body is not in close contact with the surface of the sheet 11, so it is difficult to transmit information by vibration, and since the human body covers the diaphragm 240, it is difficult to transmit sound, so the sound is more difficult than in the non-contact state. This is to raise the output level of the body and make it easier to transmit information with a stronger sound (loud sound).
- FIG. 15 is a flowchart showing an example of the process executed by the control unit 322.
- the control unit 322 determines whether or not the predetermined notification condition is satisfied (step S1).
- the predetermined notification condition is satisfied when the control unit 322 receives a notification from the ECU 12 indicating that the predetermined notification condition is satisfied.
- the control unit 322 causes the determination unit 321 to determine the state based on the capacitance of the diaphragm 240 (step S2). As a result, the determination unit 321 determines whether the contact state, the contact state, or the contact state is based on the capacitance of the diaphragm 240, and notifies the control unit 322 of the determination result.
- step S3 determines whether or not it is in the close contact state (S3: NO)
- step S5 determines whether or not it is in the contact state
- step S6 the control unit 322 generates a strong sound in the vibration generator 200
- step S5 determines in step S5 that the determination result is not in the contact state (S5: NO)
- the control unit 322 generates a weak sound in the vibration generator 200 (step S7). This completes a series of processes.
- the control unit 322 performs the above-mentioned processing individually for all the vibration generators 200.
- control unit 322 may perform the following control. Determining the three states as described above is particularly effective for the vibration generators 200A and 200C of the backrest portion 11A.
- the seated person may lean strongly against the backrest portion 11A, may lean lightly against the backrest portion 11A, or may not lean against the backrest portion 11A. When it is strongly leaning against the backrest portion 11A, it is in a close contact state, when it is lightly leaning against the backrest portion 11A, it is in a contact state, and when it is not leaning against the backrest portion 11A, it is in a non-contact state.
- the backrest portion 11A is likely to have three states of non-contact state, close contact state, and contact state, the three states are distinguished and determined, and the vibration generators 200A and 200C are driven according to the determination result. It is effective to do.
- the vibration generator 200B arranged in the seat portion 11B may be configured to determine only whether or not it is in close contact, without necessarily determining three states. Since either the sitting state or the non-sitting state is likely to occur for the seat portion 11B, the control unit 322 generates a sound in the vibration generator 200B if it is not in close contact. If it is in close contact, the vibration generator 200B may generate vibration. That is, the vibration generator 200B does not need to determine the contact state and the non-contact state.
- the vibration generator 200B arranged on the seat portion 11B can simplify the determination process as long as it has a configuration for determining only whether or not the determination unit 321 is in close contact.
- the vibration generator 200B may be configured to determine whether it is in a contact state including a close contact state or a non-contact state, instead of determining whether or not it is in a close contact state.
- the notification received from the ECU 12 may include the following data to control the seated person to notify the direction. For example, when a lane deviation occurs and the left side of the vehicle straddles the lane, the seated person by driving the vibration generators 200A, 200B, 200C provided on the left side of the seat 11 to generate vibration or sound. May be informed that a lane departure to the left has occurred. In this case, among the vibration generators 200A, 200B, and 200C, the vibration generator 200 in which the seated person's body is in close contact generates vibration, and the vibration generator 200 in contact state generates sound. Notification with direction is possible regardless of the posture of the seated person.
- vibration generators 200A are arranged in the middle stage and the lowermost stage (lower part) of the backrest portion 11A, and three vibration generators 200C are arranged in the uppermost stage (upper part). If the back of the seated person is in close contact with the upper part of the backrest portion 11A, there is a high possibility that even if sound is generated from the vibration generator 200A in the lower part, the sound is blocked by the back and does not reach the ears of the seated person. Therefore, when the determination unit 321 determines the close contact state based on the capacitance of the diaphragm 240 of the vibration generator 200C, it does not depend on the determination result based on the capacitance of the diaphragm 240 of the vibration generator 200A. In addition, the control unit 322 may not generate sound in the vibration generator 200A. Power can be saved by not generating sound in the vibration generator 200A.
- the vibration generator 200 can present vibration or sound at the position where the proximity of the seated person is detected by the diaphragm 240. Therefore, it is possible to provide a vehicle seat system 300A, a vehicle system 300, and a vibration generator 200 capable of exhibiting vibration or sound at the detected position. Further, since the diaphragm 240 that generates sound is used as the detection electrode of the capacitance sensor, space can be saved.
- the actuator 220 is not attached to the diaphragm 240 but is attached only to the housing 260. However, the actuator 220 is attached to the diaphragm 240 and the housing 260. May be good. In that case, sound can be generated by directly vibrating the diaphragm 240 due to the vibration of the actuator 220. Further, the actuator 220 may be attached only to the diaphragm 240. In that case, the vibration of the actuator 220 causes the diaphragm 240 and the housing 260 to vibrate, so that the seat can be presented with vibration through the seat 11.
