[0060] For example, the pop-up speaker 11 may be provided inside a crash pad of the vehicle 1. The pop-up speaker 11 may pop out or pop in under the control of the pop-up speaker control device 100.

[0061] According to an exemplary embodiment of the present disclosure, the pop-up speaker control device 100 may be configured to control the pop-up speaker 11 in response to control of an operation switch 12 provided in the vehicle 1 .

[0062] For example, the operation switch 12 may be an on / off control switch of an audio system of the vehicle 1 , but the present disclosure is not limited thereto.

[0063] The operation switch 12 may output a signal for turning on or off the pop-up speaker 11. According to an exemplary embodiment of the present disclosure, the operation switch 12 may output an operation-on signal or an operation-off signal to the pop-up speaker control apparatus 100 in response to a user's manipulation.

[0064] When receiving an operation-on signal output from the operation switch 12 , the pop-up speaker control device 100 may be configured to control the pop-up operation of the pop-up speaker 11 .

[0065] For example, when receiving an operation-on signal output from the operation switch 12, the pop-up speaker control device 100 may pop up the pop-up speaker 11 in the pop-in state and move the pop-up speaker 11 to a preset upper fixing point.

[0066] When receiving the operation-off signal output from the operation switch 12 , the pop-up speaker control device 100 may be configured to control the pop-in operation of the pop-up speaker 11 .

[0067] For example, when receiving an operation-off signal output from the operation switch 12, the pop-up speaker control device 100 may pop-in the pop-up speaker 11 in the pop-up state and move the pop-up speaker 11 to a preset lower fixing point.

[0068] The state in which the pop-up speaker 11 moves to the preset upper fixed point can be expressed as "pop-up completion state", "open state", etc., and the state in which the pop-up speaker 11 moves to the preset lower fixed point can be expressed as "pop-in completion state", "closed state", etc.

[0072] The conventional pop-up speaker operates linearly, but the pop-up speaker 11 according to the exemplary embodiment of the present disclosure operates non-linearly.

[0073] The pop-up speaker 11 according to the exemplary embodiment of the present disclosure may be configured as follows: Figure 2 Simultaneous operation of the control curves shown.

[0075] exist Figure 2 , a graph is shown based on a predetermined time point of 50% of the overall operation of the pop-up speaker 11, but the criteria may be changed.

[0076] That is, the pop-up speaker control device 100 may be configured to control the pop-up speaker 11 based on a time point corresponding to a preset specific ratio during the overall operation.

[0077] The pop-up speaker control device 100 can be configured to control the pop-up speaker 11 according to Formula 1 from the operation start time point of the pop-up speaker 11 to a predetermined time point of 50% of the overall operation (first control interval), and to control the pop-up speaker 11 according to Formula 2 from the predetermined time point of 50% of the overall operation of the pop-up speaker 11 to a stop time point (second control interval).

[0078] According to an exemplary embodiment of the present disclosure, the inclination value of the gradient of the control curve in the first control interval may gradually increase, and the inclination value of the gradient of the control curve in the second control interval may gradually decrease.

[0079] According to an exemplary embodiment of the present disclosure, the control curve may include a start region (or a first region), an end region (or a second region), and a middle region (or a third region).

[0080] The start region and the end region of the control curve have gentle gradient inclination values, and the middle region defined between the start region and the end region of the control curve includes a gradient inclination value greater than the inclination values ​​of the gradient of the start region and the end region.

[0081] According to an exemplary embodiment of the present disclosure, the start region may be included in the first control curve, the end region may be included in the second control curve, and the middle region may be included in a range between the first control curve and the second control curve.

[0082] Since the starting region of the control curve includes a gentle gradient inclination value, click noise occurring in the initial operation of the pop-up speaker 11 can be minimized.

[0083] Furthermore, since the end region of the control curve includes a gentle gradient inclination value, vibration occurring when the pop-up speaker 11 stops can be minimized.

[0084] The operation start time point of the pop-up speaker 11 may include a pop-up operation start time point and a pop-in operation start time point, and the stop time point of the pop-up speaker 11 may include a pop-up operation stop time point and a pop-in operation stop time point. Here, the pop-up operation start time point may indicate a time point when the pop-up operation of the pop-up speaker 11 starts, the pop-in operation start time point may indicate a time point when the pop-in operation of the pop-up speaker 11 starts, the pop-up operation stop time point may indicate a time point when the pop-up operation of the pop-up speaker 11 stops, and the pop-in operation stop time point may indicate a time point when the pop-in operation of the pop-up speaker 11 stops.

[0085] That is, according to Figure 2The control curve shown is used to perform the pop-up operation and the pop-in operation of the pop-up speaker 11.
