[0003] With the advancement of the information society, the demand for display devices for displaying images is also increasing in various ways.

[0004] Electronic devices that use display devices as displays provide touchscreen-type user interfaces to facilitate user input. Display devices capable of touch interface processing are being developed to offer a wider range of functions.

[0005] Recently, haptic technology has been developed to provide haptic feedback to users when they touch the screen of a display device. Display devices using haptic technology generate stimulating forces to stimulate tactile receptors in the human body, and use these stimulating forces to stimulate the user's sense of touch, thereby enabling the user to recognize the touch and the texture of the touch.

[0037] The advantages and features of this disclosure, and its implementation methods, are illustrated by referring to the aspects described in the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the exemplary aspects set forth herein. Rather, these exemplary aspects are illustrative and provided to make this disclosure thorough and complete, to aid those skilled in the art in understanding the inventive concept, without limiting the scope of protection of this disclosure.

[0038] The shapes, dimensions, ratios, angles, and quantities disclosed in the accompanying drawings to describe embodiments of this disclosure are merely examples, and therefore, this disclosure is not limited to the details shown. The same reference numerals always refer to the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it is determined that they would unnecessarily obscure the focus of this disclosure.

[0039] When using the terms “comprising,” “having,” and “including” as described in this disclosure, additional parts may be added unless “only” is used. Unless otherwise stated, singular terms may include plural forms.

[0040] When interpreting components, even without an explicit description, the components are interpreted as including a range of error.

Figure 3 This is an exploded perspective view of a vibration device according to a first embodiment of the present disclosure.

[0048] Reference Figures 1 to 3The vibration device 100 according to the first embodiment of this disclosure can be configured or constructed to output one or more of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation. For example, the vibration device 100 can be configured or constructed to output one of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation, or simultaneously output two or three of them. Therefore, the vibration device 100 according to the first embodiment of this disclosure can be described as a vibrating diaphragm, actuator, transducer, flexible vibrating diaphragm, flexible vibration device, flexible actuator, flexible piezoelectric loudspeaker, membrane actuator, sound / tactile device, sound / tactile actuator, diaphragm sound / tactile actuator, or multi-tactile tactile device, but is not limited thereto.

[0050] The first to the nth vibration units 110, 120 and 130 can be arranged (or configured) parallel to each other. For example, the first to the nth vibration units 110, 120 and 130 can be arranged at predetermined intervals along a first direction X (or the X-axis direction). For example, the first direction X (or the X-axis direction) can be parallel to the long side of the vibration device 100, but is not limited thereto.

[0051] A portion of the first to nth vibrating portions 110, 120, and 130 may have different sizes or shapes.

Therefore, since a portion of the first to nth vibrating portions 110, 120, and 130 have different sizes, each of the first to nth vibrating portions 110, 120, and 130 may be configured or constructed to output any one of sound, directional sound, vibratory tactile sensation, tactile sensation, or ultrasonic tactile sensation. The first to nth vibrating portions 110, 120, and 130 may be configured or constructed to output one of sound, directional sound, vibratory tactile sensation, tactile sensation, or ultrasonic tactile sensation, or simultaneously output two or three of them.

[0052] The vibration device 100 according to the first embodiment of the present disclosure can be a rectangular shape with a long side and a short side, and can include a first region A1, a second region A2 and a third region A3.

[0060] According to an embodiment, the plurality of first vibration devices 111 may be spaced apart from each other along each of the first direction X and the second direction Y to minimize vibration interference between them. For example, the spacing (or pitch) of the plurality of first vibration devices 111 along each of the first direction X and the second direction Y may be equal to or greater than the first length L1 or the second length L2.

For example, the third length L3 may be equal to the fourth length L4, but is not limited thereto. The third length L3 may be equal to the first length L1, and the fourth length L4 may be equal to the second length L2, but is not limited thereto. For example, each of the third length L3 and the fourth length L4 may be 10 mm, but is not limited thereto. The sum of the dimensions (L3 multiplied by L4) of the plurality of second vibration devices 121 may correspond to the total dimensions of the second vibration section 120.

[0063] According to an embodiment, the plurality of second vibration devices 121 may be spaced apart from each other along each of the first direction X and the second direction Y to minimize vibration interference between them. For example, the interval (or spacing) between the plurality of second vibration devices 121 along each of the first direction X and the second direction Y may be equal to or greater than a third length L3 or a fourth length L4.

[0064] The third vibration unit 130 may include a third vibration device (or a single third vibration device) 131. The size of a third vibration device 131 may be larger than the total size of a plurality of first vibration devices 111 (or four first vibration devices 111). The size of a third vibration device 131 may be larger than the total size of a plurality of second vibration devices 121 (or four second vibration devices 121).

The dimensions of a third vibration device 131 (L5 multiplied by L6) may correspond to the overall dimensions of the third vibration section 130.

[0066] According to an embodiment, in order to minimize vibration interference between a plurality of first vibration devices 111 and a third vibration device 131, the interval (or spacing) between the first vibration part 110 and the third vibration part 130 may be equal to or greater than the first length L1. In order to minimize vibration interference between a plurality of second vibration devices 121 and a third vibration device 131, the interval (or spacing) between the second vibration part 120 and the third vibration part 130 may be equal to or greater than the third length L3.

For example, sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation can each be output through one or more of the first to nth vibration units 110, 120, and 130. For example, one of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation can be output through one or more of the first to nth vibration units 110, 120, and 130. For example, two of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation can be output simultaneously through two or more of the first to nth vibration units 110, 120, and 130. For example, the first to nth vibration units 110, 120, and 130 can simultaneously output two tactile sensations of different textures.

[0114] The vibration drive circuit 180 may include a drive signal generation unit 181 and an amplifier unit 183.

For example, the drive signal generation unit 181 can generate a directional audio signal by amplitude modulation of the sound signal and the ultrasonic carrier signal. For example, the drive signal generation unit 181 can generate a directional sound signal based on the sound signal by amplitude modulation of the ultrasonic carrier signal.

[0119] The drive signal generation unit 181 can be configured to generate a vibration tactile signal with a frequency band of 50 Hz to less than 150 Hz based on the vibration tactile sensation corresponding to the touch applied from the host control system.

[0120] The drive signal generation unit 181 can be configured to generate a tactile signal with a frequency band of 150 Hz to 300 Hz based on the tactile sensation corresponding to a tactile touch applied from the host control system.

For example, amplifier section 183 can be configured to amplify and output vibration drive signals from the first to the nth vibration sections 110, 120, and 130 according to a predetermined gain value. Therefore, the vibration drive signals output from amplifier section 183 can be provided to the corresponding vibration sections 110, 120, and 130 via signal cable 170, pad section 163, and signal supply lines 161 and 162. Thus, each of one or more first vibration devices 111, one or more second vibration devices 121, and one third vibration device 131 can be driven (or vibrated or displaced) by the vibration drive signals supplied from amplifier section 183 at the same drive frequency or at different drive frequencies.

In addition, the vibration device 100 according to the first embodiment of this disclosure can output one of sound, directional sound, vibratory tactile sensation, tactile sensation and ultrasonic tactile sensation based on the driving (or vibration or displacement) of the first to nth vibrating parts 110, 120 and 130, or can output two or three of them simultaneously, and can output tactile feedback of various textures.

[0125] Furthermore, in the vibration device 100 according to the first embodiment of this disclosure, since the third vibration device 131 with a larger size is disposed in the third region A3, stronger vibration (or displacement) can be generated in the central region, thereby improving the sound characteristics and / or sound pressure level characteristics of the bass tone band. Additionally, when tactile sensation is activated, the user recognition (or perception) characteristics of vibratory tactile sensation and / or tactile sensation can be improved.

[0126] Figure 4 This is a plan view of a vibration device according to a second embodiment of the present disclosure. Figure 4 The above reference has been modified. Figures 1 to 3 Embodiments of the first and third vibrating parts in the described vibration device. Therefore, in the following description, only the modified elements will be described in detail, while other elements will be described in contrast to those modified by other means. Figures 1 to 3 The same reference numerals are used in the accompanying drawings, and repeated descriptions of them are omitted or briefly given. Therefore, the above references Figures 1 to 3 The description may include in Figure 4 In the description.

[0131] According to a second embodiment of the present disclosure, the vibration device 200 may have the same characteristics as described above. Figures 1 to 3 The vibration device 100 according to the first embodiment of this disclosure has the same effect as described, therefore, its repeated description can be omitted.

[0132] Furthermore, in the vibration device 200 according to the second embodiment of this disclosure, since the first vibration device 111, which has a larger size, is disposed in the first region A1, strong vibration (or displacement) occurs in the first region A1, thus enabling the output of directional (or directive) sound. Moreover, when tactile sensation is activated, strong vibration (or displacement) occurs in the central region at a driving frequency of 150 Hz, thereby improving the user recognition (or perception) characteristics of vibratory tactile sensation and / or tactile sensation.

[0133] Figure 5 This is a plan view showing a vibration device according to a third embodiment of the present disclosure. Figure 5 The above reference has been modified. Figures 1 to 3 Embodiments of the first to third vibrating parts in the described vibration device. Therefore, in the following description, only the modified elements will be described in detail, and other elements will be described in contrast to those modified by other means. Figures 1 to 3 The same reference numerals are used in the accompanying drawings, and repeated descriptions of them are omitted or briefly given. Therefore, the above references Figures 1 to 3 The description may include: Figure 5 In the description.

A first vibration device 111 may have a rectangular shape having a seventh length L7 parallel to a first direction X and an eighth length L8 parallel to a second direction Y. For example, the seventh length L7 may be less than the eighth length L8. The size of a first vibration device 111 (L7 multiplied by L8) may correspond to the overall size of the first vibration unit 110.

[0136] The second vibration unit 120 may include a second vibration device (or a single second vibration device) 121. A second vibration device 121 may have a rectangular shape having a ninth length L9 parallel to the first direction X and a tenth length L10 parallel to the second direction Y. For example, the ninth length L9 may be less than the tenth length L10. A second vibration device 121 may have the same dimensions as a first vibration device 111, but is not limited thereto. The dimensions of a second vibration device 121 (L9 multiplied by L10) may correspond to the overall dimensions of the second vibration unit 120.

[0137] The third vibration unit 130 may include one or more third vibration devices 131. For example, the third vibration unit 130 may include a plurality of third vibration devices 131 spaced apart from each other along the first direction X and the second direction Y. For example, the third vibration unit 130 may include four third vibration devices 131 arranged (or configured) in a matrix, but is not limited thereto.

[0138] Each of the plurality of third vibration devices 131 may have the same dimensions. Each of the plurality of third vibration devices 131 may have a rectangular shape having a first length L1 parallel to the first direction X and a second length L2 parallel to the second direction Y. The sum of the dimensions (L1 multiplied by L2) of the plurality of third vibration devices 131 may correspond to the total dimensions of the third vibration section 130. According to an embodiment, the plurality of third vibration devices 131 may be spaced apart from each other along the first direction X and the second direction Y to minimize vibration interference between them. For example, the distance between the plurality of third vibration devices 131 along the first direction X and the second direction Y may be equal to or greater than the first length L1 or the second length L2. In addition to the plurality of third vibration devices 131 being arranged in the third region A3, the plurality of third vibration devices 131 may be related to the above-mentioned reference. Figures 1 to 3 The first vibration device 111 described is basically the same, so its repeated description can be omitted.

[0139] According to an embodiment, the sum of the dimensions of a plurality of third vibration devices (or four third vibration devices) 131 may be the same as the dimension of a first vibration device 111 and may be the same as the dimension of a second vibration device 121.

[0140] According to an embodiment, the third vibration region of a third vibration section 130 comprising a plurality of third vibration devices 131 can be larger than each of the first vibration region of a first vibration section 110 comprising a first vibration device 111 and the second vibration region of a second vibration section 120 comprising a second vibration device 121. Therefore, the sound characteristics and / or sound pressure level characteristics of the sound generated by the third vibration section 130 having a plurality of third vibration devices 131 spaced apart from each other can be improved compared to (or relative to) the sound characteristics and / or sound pressure level characteristics of the sound generated by each of the first vibration section 110 and the second vibration section 120 having a vibration device 111 and a vibration device 121, respectively.

[0141] The vibration device 300 according to the third embodiment of this disclosure may have the same characteristics as described above. Figures 1 to 3 The vibration device 100 according to the first embodiment of this disclosure has the same effect as described, therefore, its repeated description can be omitted.

[0142] Furthermore, in the vibration device 300 according to the third embodiment of this disclosure, since vibration devices 111 and 121 with relatively large sizes are provided in each of the first region A1 and the second region A2, strong vibrations (or displacements) can be generated in the first region A1 and the second region A2, and thus directional (or directive) sound can be output. Furthermore, when tactile sensation is driven based on a driving frequency of 150 Hz, strong vibrations (or displacements) can be generated in the central region, and when vibrational tactile sensation and / or tactile sensation is driven based on a driving frequency of 250 Hz, the vibration can be concentrated in the central region, thus further improving the user's recognition (or perception) characteristics of vibrational tactile sensation and / or tactile sensation.
