Description

[0001] Cross-reference to related applications

[0004] With the advancement of information-oriented society, the demand for display devices for displaying images is increasing in various ways.

[0005] To facilitate user input, electronic devices using display devices as screens provide touchscreen-type user interfaces. Display devices capable of touch interface processing are increasingly being developed to offer a wider range of functions.

[0006] 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 the tangoreceptors in the human body, and by using these forces, they stimulate the user's sense of touch, enabling the user to recognize touch and tactile texture.

[0007] Haptic feedback can be achieved by haptic modules such as voice coil motors (VCMs) or linear resonant actuators (LRAs). These haptic modules are heavy and rigid, making it difficult to achieve flexibility and thinness, and are designed to operate only at specific frequencies, thus limiting their ability to achieve haptic feedback of various textures.

[0049] In the following, exemplary embodiments of the vibration device according to the present invention will be described in detail with reference to the accompanying drawings. For ease of description, the scale of each element shown in the drawings differs from the actual scale, and therefore the device is not limited to the scale shown in the drawings.

[0051] Reference Figures 1 to 3The vibration device 100 according to the first embodiment of the present invention can be configured or constructed to output one or more of sound, directional sound, vibratory tactile sensation, texture haptic sensation, and ultrasonic haptic sensation. For example, the vibration device 100 can be configured or constructed to output one of sound, directional sound, vibratory tactile sensation, texture haptic sensation, and ultrasonic haptic sensation, or simultaneously output two or more of them. Therefore, the vibration device 100 according to the first embodiment of the present invention can be represented 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, membrane sound / tactile actuator, or multi-texture haptic device, but is not limited thereto.

[0052] The vibration device 100 according to the first embodiment of the present invention may include: a first vibration part 110, a second vibration part 120, a third vibration part 130 to an nth vibration part (where n is a natural number greater than or equal to 3, and when n equals 3, the third vibration part 130 to the nth vibration part is the third vibration part 130); a first cover member 140; and a second cover member 15.

[0053] The first vibration unit 110, the second vibration unit 120, the third vibration unit 130, and the nth vibration unit may be arranged (or configured) parallel to each other. For example, the first vibration unit 110, the second vibration unit 120, the third vibration unit 130, and the nth vibration unit may 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) may be parallel to the length of the long side of the vibration device 100, but is not limited thereto.

[0054] Some of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part may have different sizes or different shapes. For example, some of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part may have a smaller size than the other vibrating parts, or some of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part may have a different size or shape than the other vibrating parts. For example, each of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part may include any one of the following shapes: circular plate shape, elliptical plate shape, and polygonal plate shape. For example, each of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part may include any one of the following shapes: circular plate shape, elliptical plate shape, square plate shape, and triangular plate shape. Therefore, some of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part have different dimensions. Thus, each of the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part can be configured or constructed to output sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation. The first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part can be configured or constructed to output sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation, or simultaneously output two or three of them.

[0055] The vibration device 100 according to the first embodiment of the present invention may include a rectangular shape having a long side and a short side, and may include a first region A1, a second region A2 and a third region A3.

[0056] Zone A1, Zone A2, and Zone A3 can be arranged parallel to each other. For example, Zone A3 can be located between Zone A1 and Zone A2. For example, Zone A1 and Zone A2 can be arranged parallel to each other, with Zone A3 in between.

[0057] The third zone A3 may include the central portion of the vibration device 100. For example, the third zone A3 may include the central portion along the length of the long side of the vibration device 100. The third zone A3 may be located between the first zone A1 and the second zone A2.

[0058] The first zone A1 may include the portion between the first short side of the vibration device 100 and the third zone A3. For example, the first zone A1 may include a side (or left side) of the third zone A3 or a first edge of the vibration device 100.

[0059] The second zone A2 may include the portion between the second short side of the vibration device 100 and the third zone A3. For example, the second zone A2 may include the other side (or right side) of the third zone A3 or the second edge of the vibration device 100.

[0060] The first vibration unit 110 may be disposed in the first region A1, the second vibration unit 120 may be disposed in the second region A2, and the third vibration unit 130 may be disposed in the third region A3.

[0061] The first vibration unit 110 may include one or more first vibration devices 111. For example, the first vibration unit 110 may include a first vibration device (or a single first vibration device) 111 having a circular plate shape.

[0062] The second vibration unit 120 may include one or more second vibration devices 121. For example, the second vibration unit 120 may include a second vibration device (or a single second vibration device) 121 having a circular plate shape. For example, a second vibration device 121 may have the same shape and size as a first vibration device 111.

[0063] The third vibration unit 130 may include a plurality of third vibration devices 131.

[0064] According to the embodiment, a plurality of third vibration devices 131 may be spaced apart from each other along one or more of a first direction X and a second direction Y. For example, the third vibration portions 130 may be arranged in a line (or row) and have a predetermined interval along the first direction X (or the X-axis direction).

[0065] According to another embodiment, a plurality of third vibration devices 131 may be arranged in a line (or row) without spacing. For example, when a plurality of third vibration devices 131 are arranged in a side contact manner without spacing (or gap), the plurality of third vibration devices 131 may have the same vibration (or displacement) characteristics as a single vibration device (or a single vibration device) having the same size.

[0066] Each of the plurality of third vibrating devices 131 may have a triangular shape. The third vibrating section 130 may include a plurality of third vibrating devices 131 having an equilateral triangular shape. Each of the plurality of third vibrating devices 131 may include a triangular shape having the same size (or the same area). The plurality of third vibrating devices 131 having a triangular shape may be arranged at predetermined intervals or without intervals (or gaps) along a first direction X (or the X-axis direction). For example, the third vibrating section 130 may include five third vibrating devices 131. For example, the plurality of third vibrating devices 131 may be arranged to form a trapezoidal shape in a plan view, but is not limited thereto. Therefore, the third vibrating section 130 may include a trapezoidal shape in a plan view, but is not limited thereto. The plurality of third vibrating devices 131 may be arranged to form an elliptical shape in a plan view. For example, the third vibrating section 130 may include two or more third vibrating devices 131 having a triangular shape, and the two or more third vibrating devices 131 may be arranged adjacently to form a polygonal shape with 2M (where M is a natural number greater than or equal to 2) sides. For example, in a plan view, polygonal shapes may include parallelograms, rectangles, trapezoids, hexagons, octagons, or decagons, etc.

[0067] The total size (or area) of the plurality of third vibrating devices 131 may be smaller than the size (or area) of each of a first vibrating device 111 and a second vibrating device 121.

[0068] A first vibrating device 111 and a second vibrating device 121 may be relative to the central portion CP of the third zone A3 (or vibrating device 100) (see Figure 4 It has a symmetrical (or horizontal or left-right symmetrical) structure, and multiple third vibrating devices 131 can have a vertical and horizontal (or up-down and left-right symmetrical) structure relative to the central part CP of the third region A3.

[0069] According to the embodiment, the sound characteristics and / or sound pressure level characteristics of the low-frequency audio band can be improved as the size of the vibrating devices 111, 121, and 131 increases, and the sound characteristics and / or sound pressure level characteristics of the high-frequency audio band can be improved as the size of the vibrating devices 111, 121, and 131 decreases. Furthermore, as the size of the vibrating devices 111, 121, and 131 decreases, the directionality of the sound can be improved.

[0070] According to the implementation method, since the resonant frequency of the vibrating device occurs in the length direction of the vibrating device, the vibrating device with a rectangular plate shape may not be suitable for outputting ultrasonic waves, because the vibrating device is separated into two frequencies due to the length difference between the long side and the short side.

[0071] According to the embodiments, the resonator with a circular plate shape can have the highest sound pressure level characteristics. For example, when a resonator with a square plate shape and a resonator with a circular plate shape have the same area, the resonator with a circular plate shape can have a higher sound pressure level characteristic than the resonator with a square plate shape in the audible frequency range (200 Hz to 20 kHz). For example, since the resonator with a circular plate shape can have a uniform displacement over the entire area, it can have a higher average displacement than the resonator with a square plate shape (which has a non-uniform displacement at the corners).

[0072] According to the embodiments, a vibrating device with a triangular plate shape can have a sound pressure level characteristic that is lower than that of a vibrating device with a circular plate shape, and can have a sound pressure level characteristic that is higher than that of a vibrating device with a square plate shape. Multiple vibrating devices with triangular plate shapes can realize a vibrating device with a polygonal shape, wherein the polygonal shape has 2M (where M is a natural number greater than or equal to 2) sides.

[0073] Vibrating devices with a rectangular plate shape can be used for any of the following: outputting sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation, but are more preferably used for improving the sound pressure level of sound based on the resonant frequency. Vibrating devices with a circular plate shape can be used for any of the following: outputting sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation, but are more preferably used for improving the sound pressure level of sound. Multiple vibrating devices with a triangular plate shape can be used for any of the following: outputting sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation, but are more preferably used for generating (or outputting) directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation.

[0075] The vibrating layers 111a, 121a, and 131a according to embodiments of the present invention may comprise piezoelectric materials or electroactive materials having a piezoelectric effect. For example, the vibrating layers 111a, 121a, and 131a may be configured as ceramic-based piezoelectric ceramics, or as piezoelectric ceramics having a perovskite-based crystal structure. The piezoelectric ceramic may be configured as a single-crystal ceramic with a crystal structure, or as a ceramic material or polycrystalline ceramic with a polycrystalline structure.

For example, each of the plurality of piezoelectric material portions may have a hexahedral shape and may be configured in a lattice shape, but is not limited thereto. For example, each of the plurality of piezoelectric material portions may have a circular plate shape, an elliptical plate shape, or a polygonal plate shape. For example, the organic material portions may be configured to fill the gap between two adjacent piezoelectric material portions or surround each of the plurality of piezoelectric material portions, thus the organic material portions may be connected to or attached to adjacent piezoelectric material portions.

[0081] Vibrating layers 111a, 121a, and 131a can be polarized (or polarized) by, but not limited to, a defined voltage applied to the first electrode layers 111b, 121b, and 131b and the second electrode layers 111c, 121c, and 131c in a defined temperature atmosphere or a temperature atmosphere that can be changed from high temperature to room temperature. Vibrating layers 111a, 121a, and 131a can vibrate by alternately and repeatedly contracting and / or expanding according to a reverse piezoelectric effect generated by a driving signal applied externally to the first electrode layers 111b, 121b, and 131b and the second electrode layers 111c, 121c, and 131c.

[0105] According to an embodiment of the present invention, the first vibration part 110, the second vibration part 120, the third vibration part 130 to the nth vibration part can be disposed (or configured) between the first cover member 140 and the second cover member 150 by means of an adhesive member 165. Therefore, the first vibration part 110, the second vibration part 120, the third vibration part 130 to the nth vibration part can be implemented in the form of a film integrally formed with the first cover member 140 and the second cover member 150. For example, the first vibration part 110, the second vibration part 120, the third vibration part 130 to the nth vibration part can be configured or constructed as a vibration device (or a single vibration device), thus achieving the effect of single material.

[0108] A side (or end) 170e of the signal cable 170 can be accommodated (or inserted) between the first cover member 140 and the second cover member 150. For example, a side (or end) 170e of the signal cable 170 can be a portion overlapping (or connected) with the pad portion 163. For example, a side (or end) 170e of the signal cable 170 can be accommodated (or inserted) between a side edge of the first cover member 140 and a side edge of the second cover member 150. For example, a side (or end) 170e of the signal cable 170 can be inserted into an adhesive member 165 disposed between a side edge of the first cover member 140 and a side edge of the second cover member 150. Therefore, the signal cable 170 can be integrally formed with the first vibrating part 110, the second vibrating part 120, the third vibrating part 130 to the nth vibrating part. Therefore, the vibration device 100 and the signal cable 170 can be realized in the form of a membrane integrally formed with each other, thereby achieving the effect of single material.

[0112] According to the implementation, the sound signal (or sound drive signal) can be used to output sound corresponding to a sound source signal applied from the host control system, and may have a frequency band of 50 Hz to 20 kHz. For example, the sound signal may include a low-frequency sound band signal and a mid-to-high-frequency sound band signal. For example, the low-frequency sound band may be 200 Hz or less, the mid-frequency band may be 200 Hz to 3 kHz, and the high-frequency band may be 3 kHz or greater, but is not limited thereto. A directional sound signal (or directional sound drive signal) can be used to output sound corresponding to a sound source signal only in a specific direction (or area), and may include a sound signal with a frequency band of 50 Hz to less than 20 kHz and an ultrasonic carrier signal of 20 kHz (or 40 kHz) or higher.

The vibration haptic may include any one of a push haptic corresponding to a push touch, an option box haptic corresponding to a long touch, and a slide haptic corresponding to a slide touch. The vibration haptic signal may include any one of a push haptic signal corresponding to a push touch, an option box haptic signal corresponding to a long touch, and a slide haptic signal corresponding to a slide touch.

[0114] According to an implementation, the tactile signal (or tactile drive signal) can be used to output a tactile sensation corresponding to the tactile sensation (or tactile information) applied from the host control system, and may have a frequency band of 150 Hz to 300 Hz. For example, the tactile sensation (or tactile information) may include a push haptic corresponding to a push touch (or press touch), an option box haptic corresponding to a long touch, and a swipe haptic corresponding to a slide touch (or touch drag).

[0115] According to one embodiment, the ultrasonic tactile signal (or ultrasonic tactile drive signal) can be used to output ultrasonic tactile feedback corresponding to ultrasonic tactile feedback (or ultrasonic tactile information) applied from the host control system, and may have a frequency band of 40 Hz or higher. According to another embodiment, the ultrasonic tactile signal may include a vibratory tactile signal with a frequency band of 50 Hz to less than 150 Hz corresponding to vibratory tactile feedback (or vibratory tactile information) and an ultrasonic carrier signal of 40 Hz or higher.

[0116] The vibration drive circuit 180 can be configured to supply any one of the following to each of the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit: a sound signal corresponding to sound, a directional sound signal corresponding to directional sound, a vibration tactile signal corresponding to vibrational touch, a texture tactile signal corresponding to textured touch, and an ultrasonic tactile signal corresponding to ultrasonic touch.

[0117] According to the embodiment, each of the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit can output any one of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation. For example, sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation can each be output by one or more of the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit. For example, one of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation can be output by one or more of the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit. For example, two of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation can be simultaneously output by two or more of the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit. For example, the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit can simultaneously output two different tactile sensations.

[0118] The vibration drive circuit 180 may include a drive signal generation unit 181 and an amplifier unit 183.

[0119] The drive signal generation unit 181 can be a sound source processing circuit or a vibration control circuit.

[0120] The drive signal generating unit 181 can be configured to supply any one of the following to each of the first vibration unit 110, the second vibration unit 120, the third vibration unit 130 to the nth vibration unit: a sound signal corresponding to sound, a directional sound signal corresponding to directional sound, a vibration tactile signal corresponding to vibration tactile sensation, a texture tactile signal corresponding to texture tactile sensation, and an ultrasonic tactile signal corresponding to ultrasonic tactile sensation.

[0121] According to an embodiment, the drive signal generation unit 181 can be configured to generate a sound signal with a frequency band of 50Hz to 20kHz based on a sound source signal applied from the host control system.

[0122] The drive signal generation unit 181 can be configured to generate a directional sound signal based on a sound source signal applied from the host control system, comprising a sound signal having a frequency band of 50 Hz to less than 20 kHz and an ultrasonic carrier signal of 20 kHz (or 40 kHz) or higher. 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 by amplitude modulation of the ultrasonic carrier signal based on the sound signal.

[0123] 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.

[0124] 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, the tactile sensation may include a push sensation corresponding to a push touch, an option box sensation corresponding to a long touch, and a slide sensation corresponding to a swipe touch. For example, the drive signal generation unit 181 can be configured to generate a tactile signal based on the tactile sensation that corresponds to any one of the push sensation signal corresponding to a push touch, the option box sensation signal corresponding to a long touch, and the slide sensation signal corresponding to a swipe touch.

[0125] The drive signal generation unit 181 can be configured to generate an ultrasonic tactile signal with a frequency band of 40 kHz or higher based on the tactile sensation corresponding to the touch applied from the host control system.

[0126] According to an embodiment, the drive signal generation unit 181 may include an internal memory that stores frequency information and waveform information for tactile signals corresponding to tactile sensations. For example, the internal memory may be configured to store push tactile frequency information and push tactile waveform information for push tactile signals, option box tactile frequency information and option box tactile waveform information for option box tactile signals, and slide tactile frequency information and slide tactile waveform information for slide tactile signals.

[0127] Amplifier section 183 can be configured to amplify and output vibration drive signals from the first vibration unit 110, second vibration unit 120, third vibration unit 130 to the nth vibration unit supplied from drive signal generation section 181. For example, amplifier section 183 can be configured to amplify and output vibration drive signals from the first vibration unit 110, second vibration unit 120, third vibration unit 130 to the nth vibration unit according to a predetermined gain value. Therefore, the vibration drive signal output from amplifier section 183 can be supplied to the corresponding vibration units 110, 120 and 130 via signal cable 170, pad section 163 and signal supply lines 161 and 162. Therefore, each of one or more first vibration devices 111, one or more second vibration devices 121 and multiple third vibration devices 131 can be driven (or vibrate or shift) by the vibration drive signal supplied from amplifier section 183 at the same drive frequency or different drive frequencies. For example, each of one or more first vibrating devices 111, one or more second vibrating devices 121, and one third vibrating device 131 may be driven (or vibrated or displaced) by a vibration drive signal supplied from the amplifier section 183 to output one or more of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation.

[0128] As described above, the vibration device 100 according to the first embodiment of the present invention can be disposed between the first cover member 140 and the second cover member 150, and can include a plurality of vibration portions 110, 120 and 130 having piezoelectric material, thus it can be driven at various frequencies and can achieve flexibility and thinness. Furthermore, the vibration device 100 according to the first embodiment of the present invention can output one of the following based on the driving (or vibration or displacement) of the first vibration portion 110, the second vibration portion 120, the third vibration portion 130 to the nth vibration portion: sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation, or can output two or three of them simultaneously, and can output tactile feedback of various textures.

[0129] Furthermore, in the vibration device 100 according to the first embodiment of the present invention, since the vibrating devices 111 and 121, which have relatively large sizes and circular plate shapes, are provided in each of the first region A1 and the second region A2, strong vibrations (or displacements) can be generated in each of the first region A1 and the second region A2, thereby outputting directional (or orientational) sound. Moreover, 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 vibratory 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 vibratory tactile sensation and / or tactile sensation. Furthermore, when sound is output, relatively strong vibrations can be generated in each of the first vibrating part 110 and the second vibrating part 120, which have relatively large sizes, so the vibration device 100 can vibrate uniformly over the entire area (or the entire surface).

[0130] Figure 4 This is a plan view showing a vibration device according to a second embodiment of the present invention. Figure 4 The above reference is shown. Figures 1 to 3 The third vibrating element in the described vibration device has been modified in this embodiment. Therefore, in the following description, only the modified elements will be described in detail; other elements will be described separately. Figures 1 to 3 The same reference numerals are used in the accompanying drawings, and their repeated descriptions are omitted or will be briefly given. Therefore, the above references Figures 1 to 3 The description may include in Figure 4 In the description.

[0131] Reference Figure 4 In the vibration device 200 according to the second embodiment of the present invention, the first vibration part 110 may be provided in the first region A1, the second vibration part 120 may be provided in the second region A2, and the third vibration part 130 may be provided in the third region A3.

[0132] The first vibration unit 110 may include a first vibration device (or a single first vibration device) 111 having a circular plate shape. The first vibration unit 110 may be related to the above-mentioned reference. Figures 1 to 3 The first vibrating part 110 described is basically the same, so its repeated description can be omitted.

[0133] The second vibration unit 120 may include a second vibration device (or a single second vibration device) 121 having a circular plate shape. The second vibration unit 120 may be related to the above-mentioned reference. Figures 1 to 3 The second vibration part 120 described is basically the same, therefore, its repeated description can be omitted.

[0134] The third vibration unit 130 may include a plurality of third vibration devices 131 having a triangular plate shape. The third vibration unit 130 may include a plurality of third vibration devices 131 having an equilateral triangular plate shape. Each of the plurality of third vibration devices 131 may include a triangular plate shape having the same size (or the same area). For example, the plurality of third vibration devices 131 may be configured to form a polygonal shape in a plan view, but is not limited thereto. For example, the plurality of third vibration devices 131 may be configured to form a hexagonal shape in a plan view. For example, the vertices of the plurality of third vibration devices 131 having an equilateral triangular plate shape may be set to face the central portion CP of the third region A3 (or vibration device 200). For example, the third vibration unit 130 may include six third vibration devices 131 having an equilateral triangular plate shape. The six third vibration devices 131 may be configured to form a hexagonal shape in a plan view.

[0135] According to one embodiment, the distances between the vertices of a plurality of third vibrating devices 131 having an equilateral triangular shape and the center portion CP of the third region A3 (or vibrating device 200) can all be the same. Therefore, the plurality of third vibrating devices 131 can be configured to form a regular hexagonal shape, and thus can be implemented as a vibration source (or vibration body) with a near-circular shape.

[0136] According to another embodiment, such as Figure 5 As shown, the distances between the vertices of the plurality of third vibrating devices 131, each having an equilateral triangular shape, and the center portion CP of the third region A3, can vary. For example, when the plurality of third vibrating devices 131 are arranged in two rows and three columns (2×3) in the third region A3, the distance between the vertex of each of the plurality of third vibrating devices 131 and the center portion CP of the third region A3 may be closer for the third vibrating devices 131 arranged in the second column than for the third vibrating devices 131 arranged in the first and third columns. Therefore, the plurality of third vibrating devices 131 can be configured to form a hexagonal shape other than a regular hexagonal shape, and can be implemented as a vibration source (or vibration body) with a near-circular or oval (or elliptical) shape.

[0137] The total size (or area) of the plurality of third vibrating devices 131 may be smaller than each of a first vibrating device 111 and a second vibrating device 121.

[0138] A first vibrating device 111 and a second vibrating device 121 may have a symmetrical (or horizontal or left-right symmetrical) structure relative to the central portion CP of the third region A3, and a plurality of third vibrating devices 131 may have a vertical and horizontal (or up-down and left-right symmetrical) structure relative to the central portion CP of the third region A3.

[0139] In addition to the six third vibrating devices 131 having the shape of equilateral triangles being arranged to form a regular hexagonal shape in the plan view, the third vibrating part 130 can be compared with the above-mentioned reference. Figures 1 to 3 The first vibrating part 130 described is basically the same, therefore, its repeated description can be omitted.

[0140] Since the plurality of third vibrating devices 131 can be configured to form a regular hexagonal shape, the third vibrating part 130 according to one embodiment can be implemented as a vibration source (or vibrating body) with a near-circular shape, thereby improving vibration characteristics or sound output characteristics, and can have similar sound characteristics and / or sound pressure level characteristics to each of the first vibrating part 110 and the second vibrating part 120 having circular plate-shaped vibrating devices 111 and 121.

[0141] Since the vibration device 200 according to the second embodiment of the present invention may have the same characteristics as the above reference... Figures 1 to 3 The vibration device 100 according to the first embodiment of the present invention has the same effects, and therefore its repeated description can be omitted. Furthermore, in the vibration device 200 according to the second embodiment of the present invention, since the vibrating devices 111 and 121 having a circular plate shape can be respectively disposed in the first region A1 and the second region A2, and a plurality of third vibrating devices 131 forming a near-circular regular hexagonal shape can be disposed in the third region A3, strong vibration (or displacement) can be generated in the central region, thereby improving the sound characteristics and / or sound pressure level characteristics of the low-frequency audio band.

[0142] Figure 6 This is a plan view showing a vibration device according to a third embodiment of the present invention. Figure 6 The above reference is shown. Figures 1 to 3 The first to third vibrating parts of the described vibration device have been modified in this embodiment. Therefore, in the following description, only the modified elements will be described in detail; other elements will be described using [other components]. Figures 1 to 3 The same reference numerals are used in the accompanying drawings, and their repeated descriptions are omitted or will be briefly given. Therefore, the above references Figures 1 to 3 The description may include in Figure 6 In the description.

[0143] Reference Figure 6 In the vibration device 300 according to the third embodiment of the present invention, the first vibration part 110 may be provided in the first region A1, the second vibration part 120 may be provided in the second region A2, and the third vibration part 130 may be provided in the third region A3.

[0144] The first vibration unit 110 may include a first vibration device (or a single first vibration device) 111 having a quadrilateral plate shape. A first vibration device 111 may have a rectangular plate shape or a rectangular shape, having a long side parallel to the short side of the vibration device 300 and a short side parallel to the long side of the vibration device 300, but is not limited thereto. For example, a first vibration device 111 may have a square plate shape or a rectangular shape. Besides a first vibration device 111 having a quadrilateral plate shape (or a rectangular plate shape or a square plate shape), the first vibration unit 110 may be similar to the above-mentioned... Figures 1 to 3 The first vibrating part 110 described is basically the same, so its repeated description can be omitted.

[0145] The second vibration unit 120 may include a second vibration device (or a single second vibration device) 121 having a quadrilateral plate shape. A second vibration device 121 may have the same shape as a first vibration device 111, but is not limited thereto. For example, a second vibration device 121 may have the same shape as a first vibration device 111, either a rectangular plate shape or a square plate shape, or it may have a different shape. Furthermore, a second vibration device 121 may have the same dimensions (or the same area) as a first vibration device 111, or it may have different dimensions (or different areas).

[0146] Each of the first vibrating part 110 and the second vibrating part 120 can output any one of sound, directional sound, vibratory tactile sensation, tactile sensation, and ultrasonic tactile sensation. In addition, each of the first vibrating part 110 and the second vibrating part 120 includes a vibrating device 111 and 121 having a quadrilateral shape, and therefore can have a relatively large size for improving the sound pressure level of the sound based on the resonant frequency.

[0147] The third vibration unit 130 may include a plurality of third vibration devices 131 having a triangular plate shape. Some of the plurality of third vibration devices 131 may have isosceles triangular plate shapes of different sizes (or different areas).

[0148] According to one embodiment, a plurality of third vibrating devices 131 having an isosceles triangle shape can be configured to form a quadrilateral shape (or a rectangular shape) in a plan view. For example, the isosceles triangles of adjacent third vibrating devices 131 having an isosceles triangle shape can contact each other without gaps (or intervals). For example, the vertex of each of the plurality of third vibrating devices 131 having an isosceles triangle shape can be located at the center of the third region A3 (or the center of the vibration device 200). Therefore, the third vibrating section 130 can have a rectangular shape in a plan view, but is not limited thereto.

[0149] According to another embodiment, the isosceles triangles of adjacent third vibrating devices 131 having the shape of an isosceles triangle can be separated by a predetermined interval. Therefore, in a plan view, the plurality of third vibrating devices 131 (or third vibrating parts 130) can have a quadrilateral shape (or a square shape).

[0150] The third vibration unit 130 may include four third vibration devices 131 having an isosceles triangular plate shape. Among the four third vibration devices 131, the dimensions of the two third vibration devices 131 whose bases are parallel to the short side of the vibration device 300 may be smaller than the dimensions of the two third vibration devices 131 whose bases are parallel to the long side of the vibration device 300. As one embodiment, the four third vibration devices 131 having the isosceles triangular plate shape may be arranged to contact each other without gaps (or intervals), and thus may be configured to form a rectangular shape in a plan view, but is not limited thereto. As another embodiment, the four third vibration devices 131 having the isosceles triangular plate shape may be separated by a predetermined interval; therefore, the four third vibration devices 131 (or the third vibration unit 130) may have a quadrilateral shape (or a square shape) in a plan view.

[0151] The total size (or total area) of the plurality of third vibrating devices 131 may be smaller than each of a first vibrating device 111 and a second vibrating device 121.

[0152] A first vibrating device 111 and a second vibrating device 121 may have a symmetrical (or horizontal or left-right symmetrical) structure relative to the central portion CP of the third region A3, and a plurality of third vibrating devices 131 may have a vertical and horizontal (or up-down and left-right symmetrical) structure relative to the central portion CP of the third region A3.

[0153] Except for the four third vibrating devices 131, which are shaped like isosceles triangles and are arranged to form a rectangular (or square) shape in the plan view, the third vibrating part 130 can be referred to above. Figures 1 to 3 The third vibration part 130 described is basically the same, so its repeated description can be omitted.

In addition, when tactile sensation is activated, the user's recognition (or perception) characteristics of vibratory tactile sensation and / or tactile sensation can be further improved.

[0155] Since the vibration device 300 according to the third embodiment of the present invention may have the same characteristics as the above references Figures 1 to 3The vibration device 100 according to the first embodiment of the present invention has the same effect, and therefore its repeated description can be omitted. Furthermore, in the vibration device 300 according to the third embodiment of the present invention, since the vibrating devices 111 and 121, which have relatively large sizes and quadrilateral shapes, can be respectively disposed in the first region A1 and the second region A2, strong vibrations (or displacements) can be generated in each of the first region A1 and the second region A2, thereby outputting directional (or orientational) sound. Additionally, since a plurality of third vibrating devices 131, which have isosceles triangular shapes, are disposed in the third region A3 to form a quadrilateral shape, strong vibrations (or displacements) can be generated in the central region when tactile sensation is driven based on a driving frequency of 150 Hz, and when vibratory 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, thereby further improving the user's recognition (or perception) characteristics of vibratory tactile sensation and / or tactile sensation. Furthermore, when outputting sound, relatively strong vibrations can be generated in each of the first vibrating part 110 and the second vibrating part 120, which have relatively large dimensions, so that the vibration device 300 can vibrate uniformly over the entire area (or the entire surface).

[0159] The second vibration unit 120 may include a plurality of second vibration devices 121 having a triangular or equilateral triangular shape. For example, in addition to the plurality of second vibration devices 121 being disposed at the second region A2, the plurality of second vibration devices 121 may be associated with the above-mentioned reference. Figure 4 or Figure 5 The multiple third vibration devices 131 described are essentially the same; therefore, their repeated descriptions can be omitted. For example, Figure 7 The second vibrating part 120 shown can be referred to above. Figures 1 to 4 The multiple third vibration devices 131 described above can be replaced, or can be referred to above. Figure 5 or Figure 6 The described multiple third vibration devices 131 are replaced.

For example, the size (or area) of a third vibrating device 131 may be larger than the size (or area) of a first vibrating device 111, but is not limited thereto.

[0162] The vibration device 400 according to the fourth embodiment of the present invention may have the same features as described above. Figures 1 to 3 The vibration device 100 described according to the first embodiment has the same effect, therefore, its repeated description can be omitted.

[0163] In the vibration device 400 according to the fourth embodiment of the present invention, since a relatively large quadrilateral plate-shaped vibrating device 111 can be provided in the first region A1, strong vibration (or displacement) can be generated in the first region A1, thereby outputting directional (or directional) sound. Furthermore, since a relatively large circular plate-shaped third vibrating device 131 can be provided in the third region A3, strong vibration (or displacement) can be generated in the central region, thereby improving the sound characteristics and / or sound pressure level characteristics of the low-frequency audio band. Furthermore, when tactile stimulation is activated, the user's recognition (or perception) of vibratory tactile sensation and / or tactile sensation can be further improved.

[0166] According to the implementation method, the push haptic signal THS1 can be generated to achieve a forward and backward (or forward and backward) decay effect. For example, the push haptic signal THS1 may include multiple push haptic waveforms generated intermittently. Each of the multiple push haptic waveforms may include a sine wave having a first segment with gradually increasing amplitude, a second segment with constant amplitude, and a third segment with gradually decreasing amplitude. Thus, a user can perceive push haptics through multiple push haptic waveforms including the first to third segments.

For example, the option box haptic signal THS2 may include multiple option box haptic waveforms generated intermittently.
