According to one example, the second vibration element 520 may be coupled to the second area A2 defined on the back of the display module 100, that is, the back of the display panel 110, through an adhesive member. Here, the second area A2 may be defined as an area adjacent to the other end 110b of the display module 100 based on the second longitudinal direction (Y) of the display module 100. For example, the second area A2 may be defined as the other edge area of the display module 100 based on the second longitudinal direction (Y) of the display module 100. Additionally, the second area A2 may be arranged symmetrically with the first area A1 based on the third area A3 located at the center of the display module 100.

If it is larger than the vibration space of the unit 500, it may be omitted, but may be formed to slim the electronic device. For example, when the first and second vibration elements 510 and 520 and the frame bottom 330 come into contact with each other, the vibration of each of the first and second vibration elements 510 and 520 is transmitted to the frame bottom 330. ) and may generate noise, and because this may change the wavelength band of the sound generated according to the vibration of the display module 100, the support frame 300 includes the first and second vibration elements 510, 520) It may have an opening 350 to prevent contact with each other or may include a contact avoidance structure.

According to one example, the driving circuit unit 700 may supply vibration signals to each of the first and second vibration elements 510 and 520 during the receiver mode. Additionally, the driving circuit unit 700 may select a contact mode or a proximity mode based on whether the user's body is in contact during the receiver mode. For example, the driving circuit unit 700 may provide a larger vibration signal to the vibration element adjacent to the position of the body contact among the first and second vibration elements 510 and 520 during the contact mode. In addition, when the position of body contact and the distance between the first and second vibration elements 510 and 520 are the same during the contact mode, the driving circuit unit 700 provides a first vibration signal to each of the first and second vibration elements 510 and 520. A vibration signal of 1 magnitude can be provided. Here, the vibration signal of the first magnitude may correspond to half the standard magnitude of the vibration signal provided to each of the first and second vibration elements 510 and 520. Additionally, the standard size of the vibration signal may correspond to the size of the sound determined according to the user's operation or program settings.

Additionally, the driving circuit unit 700 may provide a vibration signal of a second magnitude greater than the first magnitude to each of the first and second vibration elements 510 and 520 during the proximity mode. Here, the vibration signal of the second magnitude may be larger than the vibration signal of the first magnitude and may be smaller than the maximum magnitude of the vibration signal provided to each of the first and second vibration elements 510 and 520.

According to one example, the system housing 900 may include a housing bottom portion 910 disposed on the rear of the support frame 300, and a housing side wall portion 930 surrounding each side of the support frame 300. .

The housing bottom 910 may cover the driving circuit 700 disposed on the rear of the support frame 300. Accordingly, the driving circuit unit 700 may be disposed between the frame bottom 330 and the housing bottom 910 of the support frame 300.

The housing side wall portion 930 may be formed in a frame shape to surround the frame side wall portion 310 of the support frame 300. The housing side wall portion 930 may be vertically connected to each outer wall of the housing bottom portion 910. For example, the cross section between the housing side wall 930 and the housing bottom 910 may have a cross section in the shape of a “└” or “┘” shape depending on the position of the cross section.

According to one example, the housing bottom 910 and the housing side wall 930 may have structures that are independent from each other or separate from each other. For example, the housing bottom 910 may be a system rear cover that constitutes the outermost rear structure of an electronic device. At this time, the system rear cover may be made of the same material as the cover window 170, or may be made of a different glass material than the cover window 170.

Referring to FIG. 5 , the driving circuit unit 700 may include a vibration control unit 710, a detection unit 720, an audio processing unit 730, and a panel driving circuit 740.

The vibration control unit 710 controls the overall operation of the electronic device and may be expressed as a host control unit, microprocessor, or application processor.

The vibration control unit 710 can select the receiver mode or default mode depending on whether a phone is connected. For example, the vibration control unit 710 may generate a receiver mode mode signal when a phone is connected, and may generate a default mode mode signal when a phone is not connected. Here, the electronic device can perform all functions except phone calls in default mode. Also, the mode signal of the receiver mode may have a high logic level, and the mode signal of the default mode may have a low logic level.

The vibration control unit 710 may vibrate at least one of the plurality of vibration elements based on the detection signal received from the detection unit 720. Specifically, when a phone is connected, the vibration control unit 710 may select the receiver mode and receive the first detection signal S1 or the second detection signal S2 from the detection unit 720. For example, the vibration control unit 710 may select a contact mode by receiving the first detection signal S1 from the detection unit 720 when the user's body touches the touch electrode layer TEL during the receiver mode. Additionally, the vibration control unit 710 may select the proximity mode by receiving the second detection signal S2 from the detection unit 720 when the user's body approaches the touch electrode layer TEL during the receiver mode.

According to one example, in the contact mode, the vibration control unit 710 may provide a larger vibration signal VS to the vibration element adjacent to the position of body contact among the first and second vibration elements 510 and 520. For example, when the user's body (eg, ear) contacts the first area A1 of the display module 100 that overlaps the first vibration element 510, the vibration control unit 710 generates the first vibration. The vibration signal (VS) may be provided only to the element 510 and the vibration signal (VS) may not be provided to the second vibration element 520. That is, the vibration control unit 710 generates the first vibration when the user's body (for example, an ear) is in contact with a position very close to the first vibration element 510 and a considerable distance away from the second vibration element 520. The vibration signal VS can be concentrated on the device 510, and the first vibration device 510 can output sound toward the user's ears.

The ratio of the magnitude of the vibration signal (VS) can be determined. Optionally, when the distance between the first vibration element 510 and the position of body contact is significantly smaller than the distance between the second vibration element 520 and the position of body contact, the vibration control unit 710 adjusts the vibration control unit 710 to 80% of the reference size. A vibration signal (VS) corresponding to can be provided to the first vibration element 510, and a vibration signal (VS) corresponding to 20% of the standard size can be provided to the second vibration element 520.

A vibration signal (VS) of a larger magnitude than the vibration signal (VS) may be provided to the first vibration element 510.

For another example, in the contact mode, the vibration control unit 710 moves the user's body to the third area A3 of the display module 100 that does not overlap each of the first and second vibration elements 510 and 520. When contacted, a vibration signal VS corresponding to 40 to 60% of the reference size may be provided to each of the first and second vibration elements 510 and 520.

The ratio of the magnitude of the vibration signal (VS) can be determined. Optionally, when the distance between the first vibration element 510 and the position of body contact is slightly smaller than the distance between the second vibration element 520 and the position of body contact, the vibration control unit 710 is configured to adjust 55% of the reference size. A vibration signal (VS) corresponding to % may be provided to the first vibration element 510, and a vibration signal (VS) corresponding to 45% of the standard size may be provided to the second vibration element 520. That is, when the vibration control unit 710 contacts the user's body (for example, an ear) at a position slightly closer to the first vibration element 510 than the second vibration element 520, the second vibration element 520 A vibration signal (VS) of a slightly larger size than the vibration signal (VS) provided to may be provided to the first vibration element 510.

For example, the vibration control unit 710 selects the contact mode when the size of the first detection signal S1 exceeds the preset touch area threshold, and the vibration control unit 710 selects the contact mode when the size of the first detection signal S1 exceeds the preset touch area threshold. If it is below this value, you can select haptic mode. Here, the touch area threshold may be determined by considering the area where the user's ear or face contacts the display module 100 and the area where the user's finger or touch pen contacts the display module 100. Accordingly, when the size of the first detection signal S1 exceeds the preset touch area threshold, the vibration control unit 710 recognizes that the user's ear or face is in contact with the display module 100, selects the contact mode, and vibrates. The generator 500 can be vibrated. Here, the method by which the vibration control unit 710 drives the vibration generator 500 has been described in FIG. 5 and will therefore be omitted. In addition, if the size of the first detection signal S1 is less than or equal to a preset touch area threshold, the vibration control unit 710 recognizes that the user's finger or touch pen is in contact with the display module 100, selects the haptic mode, and performs haptic vibration. The generator 600 can be vibrated.

Optionally, since a user touch on the display module 100 may occur simultaneously in a plurality of areas of the display module 100, the vibration control unit 710 may be configured to operate in a contact mode for each of the plurality of user touches generated at the same time. Alternatively, you can select different haptic modes.

Additionally, the vibration control unit 710 may select the proximity mode by receiving the second detection signal S2 from the detection unit 720 when the user's body approaches the touch electrode layer TEL during the receiver mode.

Haptic vibration can be generated. Specifically, in the haptic mode, the vibration control unit 710 may provide a haptic signal (HS) to a haptic vibration element corresponding to the position of body contact among the first to third haptic vibration elements 610, 620, and 630. , At least one haptic vibration element among the first to third haptic vibration elements 610, 620, and 630 may generate haptic vibration at a position of body contact.

For example, when the user's body (e.g., a finger) contacts the first area A1 of the display module 100 that overlaps the first haptic vibration element 610, the vibration control unit 710 A haptic signal (HS) may be provided to the haptic vibration element 610. That is, the vibration control unit 710 provides a haptic signal (HS) to the haptic vibration element corresponding to the position of body contact, thereby providing a haptic effect corresponding to the user's touch to the front (Z) of the display module 100. You can.

Each can be properly driven, and power consumed by the vibration generator 500 and the haptic vibration generator 600 can be reduced.

The detection unit 720 may be mounted on the display panel 110 or a circuit board and connected to the touch electrode layer (TEL) of the touch panel 150. That is, the detection unit 720 can sense the user's touch through the touch electrodes (TE) provided on the touch electrode layer (TEL). Specifically, the detection unit 720 receives the touch sensing signal (TS) from the touch electrode layer (TEL) of the touch panel 150 during the receiver mode and generates the first and second detection signals (S1 and S2) to transmit the vibration control unit ( 710). For example, the detection unit 720 generates a first detection signal (S1) when the user's body touches the touch electrode layer (TEL), and a second detection signal (S2) when the user's body approaches the touch electrode layer (TEL). ) can be created. Here, the user's body may correspond to the ears, face, or fingers.

The panel driving circuit 740 may be mounted on the display panel 110 or a circuit board to display an image on the display panel 110.

The haptic output unit 750 may receive the haptic signal HS generated by the vibration control unit 710 and generate a haptic driving voltage that causes the haptic vibration generator 600 to vibrate. Specifically, the haptic output unit 750 amplifies the haptic signal HS provided from the vibration control unit 710 during the receiver mode to generate a haptic driving voltage, and applies the generated haptic driving voltage to the first to third haptic vibration elements. It can be provided to at least one of (610, 620, 630). Specifically, the haptic output unit 750 converts the positive polarity haptic signal and the negative polarity haptic signal into a positive polarity haptic drive voltage and a negative polarity haptic drive voltage, respectively, according to the set gain value or the gain value adjusted by the vibration control unit 710. It can be amplified and output as voltage. For example, the haptic output unit 750 provides a first haptic driving voltage (Vhd1+) of positive polarity to the first electrode (E1) of the first haptic vibration element 610, and provides a second haptic driving voltage (Vhd2+) of positive polarity. ) is provided to the first electrode (E1) of the second haptic vibration element 620, and the third haptic driving voltage (Vhd3+) of positive polarity is provided to the first electrode (E1) of the third haptic vibration element 630. You can. And, the haptic output unit 750 provides a negative first haptic driving voltage (Vhd1-) to the second electrode (E2) of the first haptic vibration element 610, and a negative second haptic driving voltage (Vhd1-). Vhd2-) is provided to the second electrode (E2) of the second haptic vibration element 620, and a third haptic driving voltage (Vhd3-) of negative polarity is provided to the second electrode (E2) of the third haptic vibration element 630. ) can be provided. This haptic output unit 750 may be built into the vibration control unit 710.

According to one example, each of the first to third haptic vibration elements 610, 620, and 630 and each of the first and second vibration elements 510 and 520 may share a piezoelectric material layer formed integrally. In addition, each of the first to third haptic vibration elements 610, 620, and 630 and each of the first and second vibration elements 510 and 520 may include a first electrode E1 spaced apart from each other.

(E2) may be included. In this way, even though the vibration generator 500 and the haptic vibration generator 600 share the piezoelectric material layer (PM) and the second electrode (E2) formed integrally, they include a separate first electrode (E1) and thus are connected to each other. Can be driven independently.

FIG. 12 is a flowchart for explaining an example of a method of driving the electronic device shown in FIG. 9.

Referring to FIG. 12, the vibration control unit 710 can select the receiver mode or the default mode depending on whether the phone is connected (S201).

When a phone is connected, the vibration control unit 710 can select the receiver mode by generating a mode signal for the receiver mode (S202).

The vibration control unit 710 can select whether to enter the proximity mode based on whether the user's body is in contact (S203). For example, the vibration control unit 710 may select the proximity mode when the user's body approaches the display module 100 without being in contact with the display module 100.

The vibration control unit 710 may select a contact mode or a haptic mode based on the size of the first detection signal S1 when the user's body touches the touch electrode layer TEL (S204). Specifically, the detection unit 120 may generate a first detection signal S1 when the user's body touches the touch electrode layer TEL during the receiver mode and provide the first detection signal S1 to the vibration control unit 710.

The vibration control unit 710 may select a contact mode when the size of the first detection signal S1 exceeds a preset touch area threshold (S205).

In the contact mode, the vibration control unit 710 may provide a larger vibration signal VS to the vibration element adjacent to the position of body contact among the first and second vibration elements 510 and 520 (S206). Therefore, when the size of the first detection signal S1 exceeds the preset touch area threshold, the vibration control unit 710 recognizes that the user's ear or face is in contact with the display module 100, selects the contact mode, and vibrates. The generator 500 can be vibrated.

The vibration control unit 710 may select the haptic mode if the size of the first detection signal S1 is less than or equal to a preset touch area threshold (S207).

In the haptic mode, the vibration control unit 710 may provide a haptic signal HS to the haptic vibration element corresponding to the position of body contact (S208). The haptic vibration generator 600 may generate haptic vibration at a location of body contact based on the haptic signal HS. For example, when the user's body (e.g., a finger) contacts the first area A1 of the display module 100 that overlaps the first haptic vibration element 610, the vibration control unit 710 A haptic signal (HS) may be provided to the haptic vibration element 610.

The vibration control unit 710 may select a proximity mode when the user's body approaches the touch electrode layer (TEL) (S209). Specifically, the detection unit 120 may generate a second detection signal S2 when the user's body approaches the touch electrode layer TEL during the receiver mode and provide the second detection signal S2 to the vibration control unit 710. Accordingly, the vibration control unit 710 may select the proximity mode by receiving the second detection signal S2 from the detection unit 720 when the user's body approaches the touch electrode layer TEL.

The vibration control unit 710 provides a vibration signal (VS) of a second size larger than the first size (for example, half the reference size) to each of the first and second vibration elements 510 and 520 in the proximity mode. You can do it (S210).

If the phone is not connected, the vibration control unit 710 can select the default mode by generating a mode signal for the default mode (S211).

FIG. 13 is a circuit block diagram for explaining another example of the driving circuit shown in FIG. 9, and FIG. 14 is a diagram showing the inclination of the display module shown in FIG. 9. Here, the driving circuit unit 700 shown in FIG. 13 further includes a gyro sensor 760, and the same configuration as the above-described configuration will be briefly described or omitted.

13 and 14, the driving circuit unit 700 may further include a gyro sensor 760 that detects tilt information of the display module 100 based on the acceleration and rotation angle of the display module 100. .

In Figure 14a, the gyro sensor 760 is the first sensor 760 when the angle θ1 formed between the inner center of the electronic device and the upper center of the electronic device is less than 90 degrees with respect to the vertical axis extending in the vertical direction from the inner center of the electronic device. A tilt signal may be provided to the detector 720. That is, when the position of the first vibration element 510 is higher than the position of the second vibration element 520, the gyro sensor 760 may provide the first tilt signal to the detection unit 720.

The detector 720 generates a first detection signal or a second detection signal by driving a touch area corresponding to tilt information among the first to third touch areas TA1, TA2, and TA3 of the touch electrode layer (TEL) in the receiver mode. can do. Specifically, when the detection unit 720 receives the first tilt signal from the gyro sensor 760, the height of the first touch area (TA1) of the touch electrode layer (TEL) increases with the height of the second and third touch areas (TA2 and TA3). By recognizing that it is higher than the height, the first touch area TA1 can be driven. That is, the detection unit 720 can detect whether the user's body touches the first touch area TA1 by driving only the first touch area TA1. For example, the detector 720 may generate the first detection signal S1 when the user's body touches the first touch area TA1, and when the user's body approaches the first touch area TA1 A second detection signal S2 may be generated. In this way, the detection unit 720 detects whether the user's body is in contact by driving only the first touch area TA1 of the touch electrode layer TEL, thereby reducing power consumption for driving the touch panel 150.

According to one example, in the contact mode, the vibration control unit 710 may provide a larger vibration signal VS to the vibration element adjacent to the position of body contact among the first and second vibration elements 510 and 520. For example, when the user's body (e.g., ear) contacts the first area A1 of the display module 100 that overlaps the first vibration element 510, the vibration control unit 710 ( 710) may provide the vibration signal (VS) only to the first vibration element 510 and may not provide the vibration signal (VS) to the second vibration element 520. That is, when the vibration control unit 710 receives the first tilt signal, the user's body (for example, ears) is very close to the first vibration element 510 and is at a considerable distance from the second vibration element 520. When touched at a spaced location, the vibration signal VS can be concentrated on the first vibration element 510, and the first vibration element 510 can output sound toward the user's ears.

In FIG. 14b, the gyro sensor 760 detects when the angle (θ2) between the inner center of the electronic device and the top center of the electronic device exceeds 90 degrees with respect to the vertical axis extending in the vertical direction from the inner center of the electronic device. A second slope signal may be provided to the detector 720. That is, when the position of the second vibration element 520 is higher than the position of the first vibration element 510, the gyro sensor 760 may provide the second tilt signal to the detection unit 720.

The detector 720 generates a first detection signal or a second detection signal by driving a touch area corresponding to tilt information among the first to third touch areas TA1, TA2, and TA3 of the touch electrode layer (TEL) in the receiver mode. can do. Specifically, when the detection unit 720 receives the second tilt signal from the gyro sensor 760, the height of the second touch area (TA2) of the touch electrode layer (TEL) is adjusted to the height of the first and third touch areas (TA1, TA3). By recognizing that it is higher than the height, the second touch area TA2 can be driven. That is, the detection unit 720 can detect whether the user's body touches the second touch area TA2 by driving only the second touch area TA2. For example, the detector 720 may generate the first detection signal S1 when the user's body touches the second touch area TA2, and when the user's body approaches the second touch area TA2 A second detection signal S2 may be generated. In this way, the detection unit 720 detects whether the user's body is in contact by driving only the second touch area TA2 of the touch electrode layer TEL, thereby reducing power consumption for driving the touch panel 150.

According to one example, in the contact mode, the vibration control unit 710 may provide a larger vibration signal VS to the vibration element adjacent to the position of body contact among the first and second vibration elements 510 and 520. For example, when the user's body (e.g., ear) contacts the second area A2 of the display module 100 that overlaps the second vibration element 520, the vibration control unit 710 ( 710) may provide the vibration signal (VS) only to the second vibration element 520 and not provide the vibration signal (VS) to the first vibration element 510. That is, when the vibration control unit 710 receives the second tilt signal, the user's body (eg, ears) is very close to the second vibration element 520 and is at a considerable distance from the first vibration element 510. When touched at a spaced location, the vibration signal VS can be concentrated on the second vibration element 520, and the second vibration element 520 can output sound toward the user's ears.

In FIG. 14C, when the angle θ3 between the inner center of the electronic device and the top center of the electronic device is 90 degrees with respect to the vertical axis extending vertically from the inner center of the electronic device, the gyro sensor 760 A third slope signal may be provided to the detector 720. That is, when the first and second vibration elements 510 and 520 are disposed at the same height, the gyro sensor 760 may provide a third tilt signal to the detection unit 720.

When the detection unit 720 receives the third tilt signal from the gyro sensor 760 in the receiver mode, the detection unit 720 recognizes that the heights of the first to third touch areas TA1, TA2, and TA3 of the touch electrode layer TEL are the same, The first to third touch areas TA1, TA2, and TA3 can be driven. That is, the detection unit 720 can drive the first to third touch areas (TA1, TA2, and TA3) to detect whether the user's body touches the first to third touch areas (TA1, TA2, and TA3). . In this way, the detection unit 720 detects whether the user's body is in contact by driving the first to third touch areas (TA1, TA2, and TA3), and the vibration control unit 710 detects the first and second vibration elements 510, 520) A larger vibration signal (VS) can be provided to the vibration element adjacent to the position of body contact. Therefore, the electronic device according to the present application can improve user convenience by providing a call sound with the same sound pressure no matter which area of the display module 100 the user's ear touches when the electronic device is tilted.

In FIG. 16, the gyro sensor 760 is configured to detect the first sensor 760 when the angle θ1 formed between the inner center of the electronic device and the upper center of the electronic device is less than 90 degrees with respect to the vertical axis extending in the vertical direction from the inner center of the electronic device. A slope signal may be provided to the detection unit 720 (S401). That is, when the position of the first vibration element 510 is higher than the position of the second vibration element 520, the gyro sensor 760 may provide the first tilt signal to the detection unit 720.

When the detector 720 receives the first tilt signal from the gyro sensor 760, it can drive the first touch area TA1 (S402). For example, the detector 720 may generate the first detection signal S1 when the user's body touches the first touch area TA1, and when the user's body approaches the first touch area TA1 A second detection signal S2 may be generated.

The gyro sensor 760 generates a second tilt signal when the angle (θ2) formed between the inner center of the electronic device and the upper center of the electronic device exceeds 90 degrees with respect to the vertical axis extending in the vertical direction from the inner center of the electronic device. can be provided to the detection unit 720 (S403). That is, when the position of the second vibration element 520 is higher than the position of the first vibration element 510, the gyro sensor 760 may provide the second tilt signal to the detection unit 720.

When the detection unit 720 receives the second tilt signal from the gyro sensor 760, it can drive the second touch area TA2 (S404). For example, the detector 720 may generate the first detection signal S1 when the user's body touches the second touch area TA2, and when the user's body approaches the second touch area TA2 A second detection signal S2 may be generated.

Can be provided to the detection unit 720. When the detection unit 720 receives the third tilt signal from the gyro sensor 760, it can drive the first to third touch areas TA1, TA2, and TA3 (S405).

Again in FIG. 15, the vibration control unit 710 can select whether to enter the proximity mode based on whether the user's body is in contact (S304). For example, the vibration control unit 710 may select the proximity mode when the user's body approaches the display module 100 without being in contact with the display module 100.

The vibration control unit 710 may select a contact mode or a haptic mode based on the size of the first detection signal S1 when the user's body touches the touch electrode layer TEL (S305).

The generator 500 can be vibrated.

The vibration control unit 710 may select the haptic mode if the size of the first detection signal S1 is less than or equal to a preset touch area threshold (S308).
