Description

Electronic device providing vibration using a speaker and method of operating the same

[0001] Various embodiments relate to an electronic device providing vibration using a speaker and a method of operating the same.

[0002] An electronic device may include one or more vibration motors, and may drive the vibration motors to provide a vibration (or haptic sensation) to a user when a vibration-generating event, such as a touch input or a call reception, occurs. The user may perceive the occurrence of a specific event through the vibration (or haptic sensation) provided by the electronic device.

[0003] A foldable electronic device may be in a folded state or an unfolded state. When the foldable electronic device is in the unfolded state, the vibration provided to the user may be of a level that is easily perceptible to the user. When the foldable electronic device is in the folded state, the vibration provided to the user may be of a level that is not easily perceptible to the user. Foldable electronic devices may suffer from a lack of vibration when in the folded state.

[0004] Vibration motors typically perform better with larger size, and larger motors can produce greater vibrations than smaller ones. Electronic devices, such as foldable electronic devices, often contain multiple components, and their internal space may be limited to accommodate large vibration motors. Therefore, a method for enhancing the vibration power of vibration motors without using large motors or adding additional hardware or components may be required.

[0005] Additionally, when the vibration motor outputs the maximum intensity of vibration, abnormal noise may occur.

[0006] One embodiment may provide an electronic device capable of enhancing the vibration force of a vibration motor without adding separate hardware or components.

[0007] One embodiment may provide an electronic device that prevents noise from occurring in a vibration motor.

[0008] An electronic device according to one embodiment may include a first housing, a second housing, a hinge structure connecting the first housing and the second housing and allowing the second housing to rotate about a first axis with respect to the first housing, a vibration motor located in the first housing or the second housing and outputting a first vibration, a speaker located in a housing other than the housing in which the vibration motor is located among the first housing and the second housing, and a processor located in the first housing or the second housing.

[0009] In one embodiment, the processor may control the vibration motor to output the first vibration when detecting a vibration generation event in the folded state of the electronic device. The processor may control the speaker to generate a second vibration having a frequency within a resonant frequency band of the vibration motor.

[0010] An electronic device according to one embodiment may include a plurality of housings, a hinge structure connecting the plurality of housings to each other and allowing one of the plurality of housings to rotate about a first axis relative to another of the plurality of housings, a vibration motor located in one of the plurality of housings and outputting a first vibration, a speaker located in another of the plurality of housings, and a processor located in one of the plurality of housings.

[0011] According to one embodiment, the processor may control the vibration motor to output the first vibration when detecting a vibration generation event in the folded state of the electronic device. The processor may determine a resonant frequency band of the vibration motor. The processor may control the speaker to generate a second vibration having a frequency within the determined resonant frequency band.

[0012] An operating method of an electronic device according to one embodiment may include an operation of determining whether the electronic device is in a folding state, an operation of detecting a vibration generation event when the electronic device is in the folding state, an operation of outputting a first vibration using a vibration motor when the vibration generation event is detected, and an operation of outputting a second vibration having a frequency within a resonant frequency band of the vibration motor using a speaker located in a housing different from a housing where the vibration motor is located.

[0013] An electronic device according to one embodiment can provide a user with vibration by a vibration motor and vibration by a speaker, thereby enhancing the vibration power of the vibration motor without adding separate hardware or parts to enhance the vibration power of the vibration motor.

[0014] An electronic device according to one embodiment can determine the frequency of vibration by a speaker by utilizing the bandwidth characteristics of a vibration motor, thereby providing various patterns of vibration through the speaker.

[0015] An electronic device according to one embodiment can provide a user with vibrations by a vibration motor and vibrations by a speaker together, thereby preventing noise that may occur when the vibration motor outputs vibrations at the maximum intensity.

[0016] In addition, various effects may be provided, either directly or indirectly, through this document.

The second side portion (223) may include a fourth side portion (223a) arranged substantially parallel to a folding axis (A), a fifth side portion (223b) extending from one end of the fourth side portion (223a) in a direction substantially perpendicular to the folding axis (A), and a sixth side portion (223c) extending from the other end of the fourth side portion (223a) in a direction substantially perpendicular to the folding axis (A) and substantially parallel to the fifth side portion (223b). The first side (211) and the third side (221) can face each other when the electronic device (201) is in a folded state.

[0062] In one embodiment, the electronic device (201) may include a recessed receiving portion (202) that receives a display (261) through a structural combination of the first housing (210) and the second housing (220). The receiving portion (202) may have substantially the same size as the display (261).

[0063] In one embodiment, at least a portion of the first housing (210) and the second housing (220) may be formed of a metallic or non-metallic material having any rigidity suitable for supporting the display (261).

[0064] In one embodiment, the electronic device (201) may include a plurality of speakers (not shown) and a plurality of speaker holes (255-1, 255-2). The plurality of speakers may be included in the sound output module (155) of FIG. 1. Sound generated by a first speaker among the plurality of speakers may be output to the outside of the electronic device (201) through the first speaker hole (255-1), and sound generated by a second speaker among the plurality of speakers may be output to the outside of the electronic device (201) through the second speaker hole (255-2). The first speaker and the second speaker may perform multimedia playback or recording playback. The first speaker may function as a call receiver.

[0065] In one embodiment, the first speaker may be positioned in the first housing (210), and the first speaker hole (255-1) may be formed in a portion of the first side (211). The second speaker may be positioned, for example, in the second housing (220), and the second speaker hole (255-2) may be formed in a portion of the fourth side (223a). The positions and numbers of the speakers may vary depending on the embodiment. The positions and numbers of the speaker holes (255-1, 255-2) may vary depending on the embodiment.

[0066] In one embodiment, the first rear cover (240) can be disposed on the second side (212) of the first housing (210) and can have substantially rectangular edges. At least a portion of the edges of the first rear cover (240) can be surrounded by the first housing (210). The second rear cover (250) can be disposed on the fourth side (222) of the second housing (220) and can have substantially rectangular edges. At least a portion of the edges of the second rear cover (250) can be surrounded by the second housing (220).

[0067] In one embodiment, the first rear cover (240) and the second rear cover (250) may have substantially symmetrical shapes with respect to the folding axis (A). In another embodiment, the first rear cover (240) and the second rear cover (250) may have different shapes.

[0068] In one embodiment, the first housing (210) and the first rear cover (240) may be detachably connected, coupled, or connected to each other, and the second housing (220) and the second rear cover (250) may be detachably connected, coupled, or connected to each other. In another embodiment, the first housing (210) and the first rear cover (240) may be formed integrally, and the second housing (220) and the second rear cover (250) may be formed integrally.

[0069] In one embodiment, the first housing (210), the second housing (220), the first rear cover (240), and the second rear cover (250) may be coupled to each other to provide a space in which various components of the electronic device (201) (e.g., a printed circuit board, an antenna module (197), a sensor module (176), or a battery (189)) may be placed. In one embodiment, at least one component may be visually exposed on the rear surface of the electronic device (201). For example, at least one component may be visually exposed through the first rear area (241) of the first rear cover (240). Here, the component may include a proximity sensor, a rear camera module, and / or a flash. A display (261) (e.g., a main display) may be placed on the front surface of the electronic device (201), and a display (262) (e.g., a sub display) may be placed on the rear surface. In one embodiment, at least a portion of the display (262) may be visually exposed from the first rear cover (240).

[0070] In one embodiment, the display (261) may be disposed in the receiving portion (202) formed by the housings (210, 220). For example, the display (261) may be disposed to occupy substantially most of the front surface of the electronic device (201). The front surface of the electronic device (201) may include an area where the display (261) is disposed, a portion (e.g., an edge area) of the first housing (210) adjacent to the display (261), and a portion (e.g., an edge area) of the second housing (220). The back surface of the electronic device (201) may include a first back cover (240), a portion (e.g., an edge area) of the first housing (210) adjacent to the first back cover (240), a second back cover (250), and a portion (e.g., an edge area) of the second housing (220) adjacent to the second back cover (250). In one embodiment, the display (261) may be a display in which at least some areas can be transformed into a flat or curved surface. In one embodiment, the display (261) may include a folding area (261c), a first area (261a) on a first side (e.g., upper side) based on the folding area (261c), and a second area (261b) on a second side (e.g., lower side) based on the folding area (261c). The first area (261a) may be located on a first side (211) of the first housing (210), and the second area (261b) may be located on a third side (221) of the second housing (220). However, the division of areas of the display (261) is exemplary, and the display (261) may be divided into a plurality of areas depending on the structure or function of the display (261).For example, as illustrated in FIG. 2A, the display (261) may be divided into regions by a folding region (261c) extending parallel to the X-axis or a folding axis (A), but the display (261) may also be divided into regions by another folding region (e.g., a folding region extending parallel to the Y-axis) or another folding axis (e.g., a folding axis parallel to the Y-axis). The division of regions of the display (261) as described above is merely a physical division by the housings (210, 220) and the hinge structure, and the display (261) may substantially display one screen through the housings (210, 220) and the hinge structure. In one embodiment, the first region (261a) and the second region (261b) may have a substantially symmetrical shape with respect to the folding region (261c).

[0071] In one embodiment, a hinge cover (265) may be disposed between the first housing (210) and the second housing (220) and configured to cover the hinge structure. The hinge cover (265) may be hidden by at least a portion of the first housing (210) and the second housing (220) or exposed to the outside depending on the operating state of the electronic device (201). For example, as illustrated in FIG. 2A, when the electronic device (201) is in an unfolded state, the hinge cover (e.g., the hinge cover (265) of FIG. 2B) may be hidden by the first housing (210) and the second housing (220) and not exposed to the outside, and as illustrated in FIG. 2B, when the electronic device (201) is in a folded state, the hinge cover (265) may be exposed to the outside between the first housing (210) and the second housing (220). Meanwhile, when the electronic device (201) is in an intermediate state where the first housing (210) and the second housing (220) form an angle with each other, at least a portion of the hinge cover (265) may be exposed to the outside between the first housing (210) and the second housing (220). At this time, the area of ​​the hinge cover (265) exposed to the outside may be smaller than the exposed area of ​​the hinge cover (265) when the electronic device (201) is in a folded state. In one embodiment, the hinge cover (265) may have a curved surface.

[0072] To explain the operation of the electronic device (201) according to one embodiment, when the electronic device (201) is in an unfolded state (e.g., the state of the electronic device (201) of FIG. 2A), the first housing (210) and the second housing (220) may form a first angle (e.g., about 180 degrees) with respect to each other, and the first region (261a) and the second region (261b) of the display (261) may be oriented in substantially the same direction. The folding region (261c) of the display (261) may be substantially on the same plane as the first region (261a) and the second region (261b). In another embodiment, when the electronic device (201) is in an unfolded state, the first housing (210) can rotate at a second angle (e.g., about 360 degrees) with respect to the second housing (220), so that the second side (212) and the fourth side (222) can face each other. On the other hand, when the electronic device (201) is in a folded state (e.g., the state of the electronic device (201) of FIG. 2B), the first housing (210) and the second housing (220) can face each other. The first housing (210) and the second housing (220) can form an angle of about 0 degrees to about 10 degrees, and the first region (261a) and the second region (261b) of the display (261) can face each other. At least a portion of the folding area (261c) of the display (261) may be transformed into a curved surface. Meanwhile, when the electronic device (201) is in an intermediate state, the first housing (210) and the second housing (220) may form a specific angle with each other. The angle (e.g., a third angle, about 90 degrees) formed by the first area (261a) and the second area (261b) of the display (261) with each other may be larger than the angle when the electronic device (201) is in a folded state and smaller than the angle when the electronic device (201) is in an unfolded state. At least a portion of the folding area (261c) of the display (261) may be transformed into a curved surface.At this time, the curvature of the surface of the folding area (261c) may be smaller than the curvature of the surface of the folding area (261c) when the electronic device (201) is in a folded state.

[0073] The screen area of ​​the display (262) may include a first area (262a) and a second area (262b). For example, the screen area may be an area where various objects and graphic representations are drawn. The second area (262b) may have a shape that protrudes from one edge of the first area (262a). In FIGS. 2A and 2B , the second area (262b) may be an area that protrudes from an edge adjacent to the first rear area (241) among the edges of the first area (262a). For example, an edge adjacent to the first rear area (241) of the first area (262a) may be connected to an inclined edge of the second area (262b). An edge connected to the inclined edge of the second area (262b) may be parallel to an edge adjacent to a hinge in the first area (262a). However, this is purely exemplary, and the shapes of the first region (262a) and the second region (262b) constituting the screen area of ​​the display (262) may vary depending on the design. The first region (262a) and the second region (262b) may be designed in a shape in which the display (262) can occupy the remaining area, excluding the area occupied by other components (e.g., a camera) on the surface where the display (262) is arranged. The second region (262b) may include a notch area of ​​the camera. In addition, the above division of the regions of the display (262) is merely a division according to shape for the convenience of explanation, and the two regions of the display (262) may actually display one screen. The display (262) may mainly display the screen when the electronic device (201) is in a folded state, but is not limited thereto.

[0074] Meanwhile, the electronic device described in this document is not limited to the form factor of the electronic device (201) described with reference to FIGS. 2a and 2b, and can be applied to electronic devices of various form factors.

[0075]

[0077] Referring to FIGS. 3A to 3D , an electronic device (301) according to an embodiment (e.g., the electronic device (101) of FIG. 1 ) may include housings (310, 320) that form an exterior and accommodate components therein. In an embodiment, the housings (310, 320) may include a first housing (310) and a second housing (320) that are movably coupled to each other. In an embodiment, the first housing (310) may be slidably connected to the second housing (320). For example, the first housing (310) may be connected to the second housing (320) so as to be able to move in a first movement direction (direction ① of FIG. 3B) (e.g., +Y direction) with respect to the second housing (320), or in a second movement direction (direction ② of FIG. 3B) (e.g., -Y direction) opposite to the first movement direction (direction ①). Hereinafter, in the various embodiments disclosed in this document, the first housing (310) is described as moving with respect to the second housing (320). However, since this is to describe the relative movement motion between the first housing (310) and the second housing (320), it can also be understood that the second housing (320) moves with respect to the first housing (310).

[0078] In one embodiment, the state of the electronic device (301) can change between a first state and a second state depending on the relative movement of the first housing (310) with respect to the second housing (320). In one embodiment, the electronic device (301) can have a retracted shape in the first state and an extended shape in the second state. The electronic device (301) can be used in the first state or the second state, or can be used in an intermediate state between the first state and the second state.

[0079] In one embodiment, the first housing (310) has a first side (310A) (e.g., a first front side), a second side (310B) opposite to the first side (310A) (e.g., a first back side), a first side (310C) facing a first lateral direction (e.g., a +Y direction) and positioned between the first side (310A) and the second side (310B), a second side (310D) facing a second lateral direction opposite to the first lateral direction (e.g., a -Y direction) and positioned between the first side (310A) and the second side (310B), a third side (310E) facing a third lateral direction (e.g., a +X direction) intersecting the first lateral direction and positioned between the first side (310A) and the second side (310B), and a third side The first housing (310) may include a fourth side (310F) facing in a fourth side direction opposite to the direction (e.g., -X direction) and positioned between the first side (310A) and the second side (310B). In one embodiment, the first housing (310) may include a first plate (311) and a first side frame (312) extending substantially in the thickness direction (e.g., Z-axis direction) along a border of the first plate (311). In one embodiment, the first plate (311) may form the second side (310B), and the first side frame (312) may form the first side (310C), the second side (310D), the third side (310E), and the fourth side (310F). In one embodiment, the first plate (311) and the first side frame (312) may be formed integrally or formed separately and then joined.

[0080] In one embodiment, the second housing (320) has a third side (320A) (e.g., a second front side), a fourth side (320B) opposite to the third side (320A) (e.g., a second rear side), a fifth side (320C) facing a first lateral direction (e.g., +Y direction) and positioned between the third side (320A) and the fourth side (320B), a sixth side (320D) facing a second lateral direction opposite to the first lateral direction (e.g., -Y direction) and positioned between the third side (320A) and the fourth side (320B), a seventh side (320E) facing a third lateral direction (e.g., +X direction) intersecting the first lateral direction and positioned between the third side (320A) and the fourth side (320B), and a third side The second housing (320) may include an eighth side surface (320F) facing in a fourth side direction opposite to the direction (e.g., -X direction) and positioned between the third side surface (320A) and the fourth side surface (320B). In one embodiment, the second housing (320) may include a second plate (321) and a second side frame (322) extending substantially in the thickness direction (e.g., Z-axis direction) along a border of the second plate (321). In one embodiment, the second plate (321) may form the fourth side surface (320B), and the second side frame (322) may form the fifth side surface (320C), the sixth side surface (320D), the seventh side surface (320E), and the eighth side surface (320F). In one embodiment, the second plate (321) and the second side frame (322) may be formed integrally or formed separately and then joined.

[0081] In one embodiment, the first housing (310) and the second housing (320) may form a front side (e.g., a side facing the +Z direction) of the electronic device (301) through the first side (310A) and the third side (320A), and may form a back side (e.g., a side facing the -Z direction) of the electronic device (301) through the second side (310B) and the fourth side (320B). In one embodiment, the second housing (320) may include an open portion (320G) in which at least a portion of a fifth side (320C) is open so that the first housing (310) can be partially movably inserted. However, this is just one example, and in another embodiment, the first housing (310) may include an open portion in which at least a portion of the second side (310D) is open, and the second housing (320) may be partially movably inserted into the interior of the first housing (310) through the open portion formed in the second side (310D).

[0082] In one embodiment, the electronic device (301) may include a display (361) (e.g., a flexible display or a rollable display) for displaying visual information. In one embodiment, the display (361) may be exposed to the outside of the electronic device (301) through a display area (3610) (e.g., an area visible from one side). In one embodiment, the display area (3610) may include a first area (361A) arranged parallel to the first side (310A) and the third side (320A), a second area (361B) connected to one end of the first area (361A), and a third area (361C) connected to the other end of the first area (361A). The second area (361B) and the third area (361C) may be arranged on opposite sides with respect to the first area (361A). In one embodiment, each of the second region (361B) and the third region (361C) may form a flexibly curved surface. In one embodiment, the display (361) may display a screen through the display region (3610). The display (361) may display a single connected screen through the entire display region (3610) or may display a screen through only a portion of the display region (3610). In another embodiment, the display (361) may display multiple partially distinct screens through the display region (3610). For example, the display (361) may display one screen through the first region (361A) and display a screen different from the first region (361A) through the second region (361B) and / or the third region (361C).

[0083] In one embodiment, the display (361) may include a flat portion (3611) forming at least a portion of a display area (3610), and a rolling portion (3612) (or bending portion) extending from the flat portion (3611). The rolling portion (3612) may be pulled out from the inside of the electronic device (301) to the outside, or may be pulled in from the outside of the electronic device (301) to the inside, depending on the movement of the first housing (310) relative to the second housing (320). The rolling portion (3612) pulled out to the outside of the electronic device (301) may be exposed to the outside of the electronic device (301) and form the display area (3610) together with the flat portion (3611). The area of ​​the display area (3610) may vary depending on the degree of pulling out of the rolling portion (3612).

[0084] In one embodiment, the display (361) may have a change in the area of ​​the display area (3610) (e.g., the first area (361A), the second area (361B), and the third area (361C)) as the state of the electronic device (301) changes. In one embodiment, the display area (3610) of the display (361) may form a first area (e.g., a minimum area) that is minimized in a first state of the electronic device (301) (e.g., a reduced state, as shown in FIG. 3A), and may form a second area (e.g., a maximum area) that is maximized in a second state of the electronic device (301) (e.g., an expanded state, as shown in FIG. 3C). When the electronic device (301) is between the first state and the second state, the display (361) may increase or decrease the area of ​​the display area (3610) corresponding to the state of the electronic device (301). For example, in the process of changing from the first state to the second state, when the first housing (310) moves by a certain length (d) in the first movement direction (direction ①) with respect to the second housing (320), the length of the display area (3610) parallel to the first movement direction (direction ①) may change from the first length (d1) to a second length (d2) that is increased by the certain length (d), thereby causing the display area (3610) to expand (e.g., increase the size of the display area (3610). Likewise, in the process of changing from the second state to the first state, when the first housing (310) moves by a certain length (d) in the second movement direction (② direction) with respect to the second housing (320), the length of the display area (3610) parallel to the second movement direction (② direction) changes from the second length (d2) to the first length (d1) that is reduced by the certain length (d), and the display area (3610) may be reduced (e.g., the size of the display area (3610) may be reduced). Meanwhile, while the electronic device (301) is changing between the first state and the second state, the sizes of each of the second area (361B) and the third area (361C) may be substantially constant.

[0085] In one embodiment, the electronic device (301) may include at least one of an input module (e.g., input module (150) of FIG. 1), an audio output module (e.g., audio output module (155) of FIG. 1), a camera module (380) (e.g., camera module (180) of FIG. 1), and a connector port (308).

[0086] In one embodiment, the input module can receive an input signal according to a user's operation. The input module can be disposed, for example, on the seventh side (320E) or the eighth side (320F) of the second housing (320). It should be noted that the location where the input module is disposed is not limited thereto. For example, the input module can also be disposed on the first housing (310).

[0087] In one embodiment, at least one of the first housing (310) and the second housing (320) may include a hole for radiating sound (or acoustics) generated from a speaker (e.g., the audio output module (155) of FIG. 1) to the outside. For example, the first housing (310) may include a first hole (H1) that is covered by the second housing (320) when the electronic device is in the first state and is exposed to the outside when the electronic device (301) is in the second state. For example, the second housing (320) may include a second hole (H2) formed in at least one of the sixth side (320D), the seventh side (320E), and the eighth side (320F). For example, the first hole (H1) and the second hole (H2) may be arranged to be substantially aligned with each other when the electronic device (301) is in the first state.

[0088] In one embodiment, a vibration motor (e.g., a haptic module (179) of FIG. 1) may be located in a first housing (310) of the electronic device (301). For example, the vibration motor may be mounted at location (330) of FIG. 3c.

[0089] In one embodiment, the electronic device (301) can detect a vibration generation event (e.g., a call received, a message received, a set alarm time reached, or a touch input to the display (361)) when in a first state. When the electronic device (301) detects a vibration generation event in the first state, the electronic device (301) can control a vibration motor to output vibration, and can control a speaker to output sound (or audio) having a frequency within a resonant frequency band of the vibration motor. The description of an operation of controlling a speaker (e.g., a first speaker (440) to be described later) when an electronic device (e.g., electronic device (401)) detects a vibration generation event in a folded state, which will be described later, can be applied to an operation of controlling a speaker when the electronic device (301) detects a vibration generation event in the first state.

[0090]

[0091] FIG. 4 is a block diagram illustrating an example of a configuration of an electronic device according to one embodiment.

[0092] Referring to FIG. 4, an electronic device (401) according to an embodiment (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIGS. 2A and 2B, and the electronic device (301) of FIGS. 3A to 3D) may include a processor (410) (e.g., the processor (120) of FIG. 1), a vibration motor (420) (e.g., the haptic module (179) of FIG. 1), a microphone (430), a first speaker (440), a second speaker (450), and a sensor module (460) (e.g., the sensor module (176) of FIG. 1).

[0093] In one embodiment, the processor (410) may be operatively connected to a vibration motor (420), a microphone (430), a first speaker (440), a second speaker (450), and a sensor module (460).

[0094] The microphone (430) of FIG. 4 may be included, for example, in the input module (150) of FIG. 1, and the first speaker (440) and the second speaker (450) of FIG. 4 may be included, for example, in the audio output module (155) of FIG. 1.

[0095] Although not shown in FIG. 4, the electronic device (401) may include a first housing (e.g., the first housing (210) of FIGS. 2A and 2B or the first housing (310) of FIGS. 3A to 3B) and a second housing (e.g., the second housing (220) of FIGS. 2A and 2B or the second housing (320) of FIGS. 3A to 3B).

[0096] In one embodiment, the electronic device (401) may include a hinge structure (e.g., the hinge structure described with reference to FIGS. 2A and 2B). The hinge structure may connect a first housing (210) and a second housing (220), and may allow the second housing (220) to rotate about a first axis (e.g., the folding axis (A) of FIG. 2A) relative to the first housing (210).

[0097] In one embodiment, the sensor module (460) may include a Hall sensor that generates an electrical signal (e.g., a voltage signal) in response to a magnetic field (or magnetic force) by a magnetic body. The Hall sensor may sense the magnetic field (or magnetic force) by the magnetic body to obtain data (e.g., voltage data) or an electrical signal (e.g., a voltage signal). The Hall sensor may be located, for example, in a first housing (e.g., the first housing (210)), and the magnetic body that generates the magnetic field may be located, for example, in a second housing (e.g., the second housing (220)). Depending on the implementation, the Hall sensor may be located in the second housing, and the magnetic body may be located in the first housing. When the electronic device (401) is in a folded state, the Hall sensor and the magnetic body may face each other.

[0098] In one embodiment, the processor (410) may determine the state of the electronic device (401) (e.g., unfolded state, folded state, or intermediate state) using a sensor module (460) (e.g., a Hall sensor) and a magnetic material. For example, the processor (410) may receive an electrical signal (or voltage data) from the Hall sensor. The processor (410) may determine that the electronic device (401) is in the folded state if the intensity of the received electrical signal (or the value of the voltage data) exceeds a certain range. The processor (410) may determine that the electronic device (401) is in the intermediate state if the intensity of the received electrical signal (or the value of the voltage data) is within a certain range. The processor (410) may determine that the electronic device (401) is in the unfolded state if the intensity of the received electrical signal (or the value of the voltage data) is below a certain range. According to an embodiment, the processor (410) can calculate the angle at which the electronic device (401) is folded (or the angle formed by the first housing and the second housing) based on the intensity of the received electrical signal (or the value of the voltage data), and can determine the state of the electronic device (401) (e.g., whether it is in an unfolded state, a folded state, or an intermediate state) using the calculated angle.

[0099] In one embodiment, the second speaker (450) may be a closed-type speaker. A closed-type speaker may refer to a speaker including, for example, an enclosure structure. The enclosure structure may prevent vibrations generated by the speaker (e.g., a diaphragm) from being transmitted to the outside of the speaker. The second speaker (450) may prevent vibrations generated by the second speaker (450) (e.g., a diaphragm of the second speaker (450)) from being transmitted to the outside of the second speaker (450) according to the enclosure structure.

[0100] In one embodiment, the first speaker (440) may be an open-type speaker. An open-type speaker may refer to a speaker that does not include an enclosure structure, for example. The first speaker (440) may not include an enclosure structure, so that vibrations generated by the first speaker (440) (e.g., a diaphragm of the first speaker (440)) may be transmitted to the outside of the first speaker (440). The first speaker (440) may utilize a portion of the internal space of a housing in which the first speaker (440) is located (e.g., the first housing (210, 310) or the second housing (220, 320)) as a resonance space.

[0101] In one embodiment, the housing in which the first speaker (440) is positioned and the housing in which the second speaker (450) is positioned may be different. For example, the first speaker (440) may be positioned in the first housing (e.g., the first housing (210) of FIGS. 2A and 2B or the first housing (310) of FIGS. 3A to 3D), and the second speaker (450) may be positioned in the second housing (e.g., the second housing (220) of FIGS. 2A and 2B or the second housing (320) of FIGS. 3A to 3D). This is not limited thereto, and the first speaker (440) may be positioned in the second housing, and the second speaker (450) may be positioned in the first housing.

[0102] In one embodiment, the processor (410) may detect a vibration generation event. The vibration generation event may correspond to an event that causes vibration of the vibration motor (420). The vibration generation event may include, for example, at least one of a call reception, a message reception, reaching a set alarm time, or a touch input (e.g., a touch input to the display (261) of FIG. 2A or the display (262) of FIGS. 2A and 2B), but the vibration generation event is not limited to the examples described above.

[0103] In one embodiment, when the processor (410) detects a vibration generation event, it can control the vibration motor (420) to output vibration. Hereinafter, the vibration output by the vibration motor (420) is referred to as “first vibration.”

[0104] In one embodiment, the processor (410) may detect a vibration generation event in the folded state of the electronic device (401). When the processor (410) detects a vibration generation event in the folded state of the electronic device (401), the processor (410) may use the first speaker (440) to generate vibration. When the processor (410) detects a vibration generation event in the folded state of the electronic device (401) (or when the vibration motor (420) outputs vibration), the processor (410) may control the vibration motor (420) to output the first vibration, and may control the first speaker (440) to output sound (or sound) so that vibration can be provided to the user. The electronic device (401) may provide the user with vibration by the first speaker (440) so as to reinforce the vibration force of the vibration motor (420) in the folded state. Hereinafter, the vibration provided (or generated) by the first speaker (440) is referred to as “second vibration.”

[0105] In one embodiment, when the processor (410) detects a vibration generation event in the folded state of the electronic device (401), the processor (410) may activate the microphone (430). The processor (410) may receive the operating sound of the vibration motor (420) through the activated microphone (430), and may determine the resonant frequency (or resonant frequency band) of the vibration motor (420) from the operating sound of the vibration motor (420) received from the microphone (430). For example, the frequency of the operating sound of the vibration motor (420) may correspond to the resonant frequency of the vibration motor (420). The processor (410) may perform frequency scanning on the operating sound of the vibration motor (420) received from the microphone (430) to determine the resonant frequency (or resonant frequency band) of the vibration motor (420). The resonant frequency of the vibration motor (420) may be, for example, 205 Hz, but is not limited thereto. The resonant frequency band of the vibration motor (420) may be, for example, 180 Hz to 230 Hz, but is not limited thereto.

[0106] In one embodiment, the processor (410) may generate a periodic signal (e.g., a signal that the first speaker (440) uses to generate a second vibration or sound) based on the resonant frequency of the vibration motor (420). For example, the processor (410) may determine the reciprocal of the resonant frequency of the vibration motor (420) as the period of the periodic signal, or may determine the reciprocal of any frequency within the resonant frequency band of the vibration motor (420) as the period of the periodic signal. The periodic signal may have a frequency equal to the resonant frequency of the vibration motor (420) or may have any frequency within the resonant frequency band.

[0107] In one embodiment, the processor (410) can transmit a periodic signal to the first speaker (440). The processor (410) can control the first speaker (440) so that the first speaker (440) can generate a second vibration based on the periodic signal.

[0108] In one embodiment, the processor (410) may operate so that the first vibration by the vibration motor (420) and the second vibration by the first speaker (440) are synchronized with each other. The processor (410) may control at least one of the vibration motor (420) and the first speaker (440) so that the first speaker (440) can output a sound (or audio) that matches the operating sound of the vibration motor (420). Accordingly, the processor (410) may cause the first vibration and the second vibration to be synchronized with each other.

[0109] For example, the period of the operating sound of the vibration motor (420) and the period of the periodic signal may be based on the resonant frequency of the vibration motor (420), so that the period of the operating sound of the vibration motor (420) may be substantially the same as the period of the periodic signal. The time from the time of the vibration generation event to the time of providing (or generating) the second vibration (e.g., t2) may be longer than the time from the time of the vibration generation event to the time of outputting the first vibration (e.g., t1). The processor (410) may generate the periodic signal to compensate for this time difference (e.g., the difference between t2 and t1) so that the first vibration and the second vibration are synchronized. For example, the processor (410) may generate the periodic signal so that the periodic signal leads the operating sound of the vibration motor (420) by a predetermined time value (e.g., the difference between t2 and t1). Accordingly, the first vibration and the second vibration may be synchronized.

[0110] For another example, the processor (410) may control the vibration motor (420) to output the first vibration delayed by a predetermined time value (e.g., the difference between t2 and t1) when a vibration generation event occurs. Accordingly, the first vibration and the second vibration may be synchronized.

[0111] In one embodiment, the first speaker (440) can generate the second vibration by operating using a periodic signal. For example, the first speaker (440) can include a diaphragm, and the first speaker (440) can vibrate the diaphragm based on the periodic signal. By vibrating the diaphragm of the first speaker (440), the first speaker (440) can generate the second vibration. The first speaker (440) can be an open speaker, and thus, a part of the space within the housing (e.g., the first housing) in which the first speaker (440) is positioned can be utilized as a resonance space. Accordingly, the second vibration generated by the first speaker (440) can be transmitted to the front (e.g., the first surface (211) of FIG. 2A) and the rear (e.g., the first rear cover (240) of FIGS. 2A and 2B) of the housing in which the first speaker (440) is positioned. When a vibration generating event (e.g., receiving a call, receiving a message, reaching a set alarm time, or a touch input to the display (262)) occurs while the user is holding the electronic device (401) in a folded state, the electronic device (401) can provide the user with a first vibration by the vibration motor (420) and a second vibration by the operation of the first speaker (440). The electronic device (401) can provide the user with the first vibration and the second vibration at a synchronized point in time.

[0112] In one embodiment, when the volume level of the first speaker (440) is 0 in the folded state of the electronic device (401), the intensity of the second vibration may be 0. When the volume level of the first speaker (440) is lower than a predetermined level in the folded state of the electronic device (401), the second vibration may occur, but the second vibration may have an intensity such that the user cannot feel the second vibration. When the processor (410) detects a vibration generation event in the folded state of the electronic device (401), the processor (410) may determine whether the volume level of the first speaker (440) is lower than a predetermined level. The predetermined level may represent, for example, a volume level corresponding to a minimum intensity at which the user can feel the second vibration. When the processor (410) determines that the volume level of the first speaker (440) is lower than the predetermined level, the processor (410) may control the first speaker (440) so that the volume level of the first speaker (440) is higher than or equal to the predetermined level. Accordingly, when a vibration generation event occurs in the folded state of the electronic device (401), if the volume level of the first speaker (440) is below a predetermined level, the electronic device (401) can increase the volume level of the first speaker (440) so that the volume level of the first speaker (440) is above the predetermined level. As a result, the electronic device (401) can provide the user with a second vibration due to the operation of the first speaker (440).

[0113] In one embodiment, the processor (410) can determine the frequency of the periodic signal to be the same as the resonant frequency of the vibration motor (420). The processor (410) can determine the period of the periodic signal using the reciprocal of the resonant frequency of the vibration motor (420). The frequency of the first vibration by the vibration motor (420) and the frequency of the second vibration by the first speaker (440) can be the same. The electronic device (401) can provide the user with the second vibration that is not inconsistent with the first vibration.

[0114] In one embodiment, the processor (410) may determine any frequency excluding the resonant frequency in the resonant frequency band of the vibration motor (420) as the frequency of the periodic signal. The processor (410) may determine the period of the periodic signal using the reciprocal of any frequency within the resonant frequency band of the vibration motor (420). The frequency of the first vibration by the vibration motor (420) and the frequency of the second vibration by the first speaker (440) may be different. In this case, the electronic device (401) may provide a different UX (user experience) to the user than the UX when the frequency of the first vibration and the frequency of the second vibration are the same. For example, the processor (410) may determine any frequency excluding the resonant frequency in the resonant frequency band of the vibration motor (420) as the frequency of the periodic signal so that the user can clearly recognize that a vibration generation event has occurred in the folded state of the electronic device (401).

[0115] In one embodiment, the processor (410) may determine a frequency (or period) of the periodic signal differently depending on the type of the vibration generation event. For example, when the processor (410) detects a first vibration generation event (e.g., a call reception) in the folded state of the electronic device (401), the processor (410) may determine the resonant frequency of the vibration motor (420) as the frequency of the periodic signal. The processor (410) may transmit a periodic signal having a resonant frequency of the vibration motor (420) to the first speaker (440) so that the first speaker (440) may generate a second vibration having the resonant frequency of the vibration motor (420). When the processor (410) detects a second vibration generation event (e.g., a call reception) in the folded state of the electronic device (401), the processor (410) may determine a first frequency excluding the resonant frequency from the resonant frequency band of the vibration motor (420) as the frequency of the periodic signal. The processor (410) may transmit a periodic signal having a first frequency to the first speaker (440) so that the first speaker (440) may generate a second vibration having a first frequency. When the processor (410) detects a third vibration generation event (e.g., reaching a set alarm time) in the folded state of the electronic device (401), the processor (410) may determine a second frequency excluding the resonant frequency from the resonant frequency band of the vibration motor (420) as the frequency of the periodic signal. The processor (410) may transmit a periodic signal having a second frequency to the first speaker (440) so that the first speaker (440) may generate a second vibration having a second frequency.

[0116] In one embodiment, the vibration motor (420) may be in a state where it cannot output the first vibration. For example, the vibration motor (420) may be broken or the electrical connection between the vibration motor (420) and the processor (410) may be interrupted. When the processor (410) detects a vibration generation event in a state where the vibration motor (420) is unable to output the first vibration, it may provide the second vibration to the user using the first speaker (440).

[0119] In the examples shown in FIGS. 5A, 5B, and 5C, an electronic device (401) according to one embodiment may include a first PCB (501), a second PCB (503), a camera module (505), a first housing (510) (e.g., the first housing (210) of FIGS. 2A and 2B), a second housing (520) (e.g., the second housing (220) of FIGS. 2A and 2B), and a hinge structure (530).

[0120] In one embodiment, the camera module (505) may be a rear camera module. The camera module (505) may include, for example, a first camera (505-1) (e.g., a wide-angle camera) and a second camera (505-2) (e.g., an ultra wide-angle camera).

[0121] In one embodiment, the processor (410), the first speaker (440), the first PCB (501), and the camera module (505) may be located in the first housing (510). The vibration motor (420), the microphone (430), the second speaker (450), and the second PCB (503) may be located in the second housing (520). In one embodiment, the processor (410) may be located in the first PCB (501), and the microphone (430) may be located in the second PCB (503).

[0122] In one embodiment, the first speaker (440) may include a diaphragm (540). A speaker hole (560) (e.g., the first speaker hole (255-1) of FIG. 2A) may be formed in a portion of the first housing (510). Vibration generated by the diaphragm (540) of the first speaker (440) may be transmitted to the outside of the electronic device (401) through the speaker hole (560). Accordingly, the electronic device (401) may provide sound (or acoustics) to the user through the first speaker (440).

[0123] In one embodiment, the first speaker (440) may be an open speaker. Vibration generated by the diaphragm (540) of the first speaker (440) may be transmitted to the internal space of the first housing (510).

[0124]

[0125] FIG. 6 is a drawing illustrating an example of the operation of an electronic device in a folded state according to one embodiment.

[0126] The example illustrated in FIG. 6 schematically represents a cross-section of an electronic device (401) in a folded state.

[0127] In one embodiment, when the processor (410) detects a vibration generation event, the processor (410) may control the vibration motor (420) to output a first vibration and may control the first speaker (440) to generate (or output) a second vibration. For example, when the processor (410) detects a vibration generation event, the processor (410) may determine a period of a periodic signal based on a resonant frequency of the vibration motor (420) or any frequency within a resonant frequency band, and may generate a periodic signal having the determined period and transmit the periodic signal to the first speaker (440). The first speaker (440) may operate based on the periodic signal received from the processor (410) to generate the second vibration. The generated second vibration can be transmitted to the front (e.g., the first surface (211) of FIG. 2A) and the rear (e.g., the first rear cover (240) of FIGS. 2A and 2B) of the first housing (510) through a medium (e.g., air) within the first housing (510). When a user holds the electronic device (401) in a folded state, the electronic device (401) can provide the first vibration and the second vibration to the user. The user can hear a sound (or sound) according to the second vibration of the first speaker (440). The frequency of the sound according to the second vibration can be the same as the resonance frequency of the vibration motor (420), so that the user may not feel an auditory discomfort.

[0128] Although not shown in FIG. 6, the microphone (430) may be positioned in the second housing (520) and adjacent to the vibration motor (420). When the processor (410) detects a vibration generation event, the processor (410) may receive an operating sound of the vibration motor (420) through the microphone (430). The processor (410) may control the first speaker (440) (or the sound playback timing of the first speaker (440)) through the received operating sound so that the first vibration and the second vibration can be synchronized.

[0129]

[0130] FIG. 7 is a drawing illustrating an example of the intensity of vibration caused by speaker operation in a folded state of an electronic device according to one embodiment.

[0131] An example of the rear surface of the first housing (710) of the electronic device (401) in a folded state (e.g., the first housing (210) of FIGS. 2a and 2b, and the first housing (510) of FIGS. 5b, 5c, and 6) is shown in FIG. 7.

[0132] In the example illustrated in FIG. 7, the first speaker (440) may be located near the center of the first housing (710).

[0133] In one embodiment, the processor (410) may control the first speaker (440) to output a second vibration when a vibration generation event is detected. The intensity of the second vibration may be maximum near the center of the rear surface (or the surface near the center) of the first housing (210), for example, as shown in FIG. 7, and the intensity of the second vibration may become weaker as it moves away from the center.

[0134]

[0135] FIG. 8 is a drawing illustrating an example of the frequency characteristics of a vibration motor of an electronic device according to one embodiment.

[0136] An example of a frequency characteristic (e.g., a graph of frequency and intensity) (810) of a vibration motor (e.g., a vibration motor (420) of FIG. 4) of an electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (201) of FIGS. 2A and 2B, an electronic device (301) of FIGS. 3A to 3D, and an electronic device (401) of FIG. 4) according to an embodiment of the present invention is illustrated in FIG. 8.

[0137] In the example shown in Fig. 8, the vibration motor has a resonant frequency band (or wide frequency band) (e.g. f0±50Hz ) can have. In Fig. 8, f0 can represent the resonant frequency of the vibration motor.

[0138] In one embodiment, a processor (e.g., processor (120) of FIG. 1, processor (410) of FIG. 4) can determine the frequency of a first vibration to be output by the vibration motor according to the type of vibration generation event, and can determine the frequency of the periodic signal based on the determined frequency.

[0139] For example, when the processor (410) detects a first vibration generation event (e.g., reception of a call) in a folded state of the electronic device (401), the processor (410) may determine the frequency of the first vibration to be output by the vibration motor as the resonant frequency of the vibration motor (e.g., f0 of FIG. 8), and may determine the resonant frequency of the vibration motor (e.g., f0 of FIG. 9) as the frequency of the periodic signal. The processor (410) may control the vibration motor so that the vibration motor can provide a first vibration having the resonant frequency (e.g., f0 of FIG. 8), and may control the first speaker (440) so that the second vibration having the resonant frequency (e.g., f0 of FIG. 8) can be provided.

[0140] For another example, when the processor (410) detects a second vibration generation event (e.g., a call reception) in the folded state of the electronic device (401), the processor (410) may determine the frequency of the first vibration to be output by the vibration motor as the first frequency (e.g., f1 of FIG. 8), and may determine the first frequency (e.g., f1 of FIG. 8) as the frequency of the periodic signal. The processor (410) may control the vibration motor so that the first vibration having the first frequency (e.g., f1 of FIG. 8) can be provided, and may control the first speaker (440) so that the second vibration having the first frequency (e.g., f1 of FIG. 8) can be provided.

[0141] For another example, when the processor (410) detects a third vibration generation event (e.g., reaching a set alarm time) in the folded state of the electronic device (401), the processor (410) may determine the frequency of the first vibration to be output by the vibration motor as the second frequency (e.g., f2 in FIG. 8), and may determine the second frequency (e.g., f2 in FIG. 8) as the frequency of the periodic signal. The processor (410) may control the vibration motor so that the first vibration having the second frequency (e.g., f2 in FIG. 8) can be provided, and may control the first speaker (440) so that the second vibration having the second frequency (e.g., f2 in FIG. 8) can be provided.

[0142]

[0143] FIG. 9 is a flowchart illustrating an example of a method of operating an electronic device according to one embodiment.

[0144] Referring to FIG. 9, in operation 910, an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIGS. 2A and 2B, the electronic device (301) of FIGS. 3A to 3D, and the electronic device (401) of FIG. 4) may determine whether the electronic device is in a folding state. For example, the electronic device may sense a magnetic force of a magnetic body of the electronic device using a Hall sensor, and may determine whether the electronic device is in a folding state based on data (e.g., voltage data) obtained by sensing the magnetic force. The electronic device may determine that the electronic device is in a folding state when the value of the voltage data exceeds a certain range. The electronic device may determine that the electronic device is in an intermediate state when the value of the voltage data is within a certain range. The electronic device may determine that the electronic device is in an unfolding state when the value of the voltage data is below a certain range.

[0145] In operation 920, the electronic device may detect a vibration event when the electronic device is in a folded state. The vibration event may include, for example, at least one of an incoming call, a incoming message, reaching a set alarm time, or a touch input.

[0146] In operation 930, the electronic device may output (or provide) a first vibration using a vibration motor (e.g., vibration motor (420) of FIG. 4) when detecting a vibration generation event.

[0147] In operation 940, the electronic device may output (or provide) a second vibration having a frequency within a resonant frequency band of the vibration motor by using a speaker (e.g., the first speaker (440) of FIG. 4) located in a different housing (e.g., the first housing) from the housing (e.g., the second housing) in which the vibration motor is located. For example, in operation 940, the electronic device may generate a periodic signal based on a frequency within the resonant frequency band of the vibration motor. The electronic device may generate the second vibration by operating the speaker (e.g., the first speaker (440)) with the generated periodic signal.

[0148] The embodiments described through FIGS. 1 to 8 can be applied to the operating method of the electronic device of FIG. 9.

[0149]

[0150] In one embodiment, an electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (201) of FIGS. 2A and 2B, an electronic device (301) of FIGS. 3A to 3D, and an electronic device (401) of FIG. 4) comprises a first housing (e.g., a first housing (210) of FIGS. 2A and 2B, a first housing (310) of FIGS. 3A to 3D, and a first housing (510) of FIGS. 5B and 5C), a second housing (e.g., a second housing (220) of FIGS. 2A and 2B, a second housing (320) of FIGS. 3A to 3D, and a second housing (520) of FIGS. 5B and 5C), and a hinge structure (e.g., a hinge of FIGS. 5B and 5C) connecting the first housing and the second housing and allowing the second housing to rotate about a first axis relative to the first housing. The structure (530)) may include a vibration motor (e.g., a vibration motor (420) of FIG. 4) located in the first housing or the second housing and outputting a first vibration, a speaker (e.g., a first speaker (440) of FIG. 4) located in a housing other than the housing in which the vibration motor is located among the first housing and the second housing, and a processor (e.g., a processor (120) of FIG. 1, a processor (410) of FIG. 4) located in the first housing or the second housing.

[0151] In one embodiment, the processor may control the vibration motor to output the first vibration when the vibration generation event is detected in the folded state of the electronic device. The processor may control the speaker to generate a second vibration having a frequency within a resonant frequency band of the vibration motor (e.g., a resonant frequency, a first frequency, or a second frequency).

[0152] In one embodiment, when the processor detects the vibration generation event, the processor may generate a periodic signal based on the frequency. The processor may transmit the generated periodic signal to the speaker so that the speaker operates using the generated periodic signal to generate the second vibration.

[0153] In one embodiment, when the processor detects the vibration generation event, the processor can activate a microphone, receive an operating sound of the vibration motor through the activated microphone, and control the speaker based on the received operating sound so that the first vibration and the second vibration are synchronized.

[0154] In one embodiment, the processor can determine the resonant frequency band or the resonant frequency of the vibration motor based on the received motion sound.

[0155] In one embodiment, when the processor detects the vibration generation event, the processor can determine whether the volume level of the speaker is below a predetermined level, and when the processor determines that the volume level is below the predetermined level, the processor can control the speaker so that the volume level is above the predetermined level.
