[0024] The following description relates to electronic devices and wearable devices.

[0025] Figure 1 A perspective view of an electronic device 1 according to some arrangements of the present disclosure is shown. The electronic device 1 may include an acoustic device, a wearable device, and / or a wearable acoustic device for amplifying, outputting, or transmitting an audio signal (or sound wave). The electronic device 1 may be configured to output an audio signal to a user and / or input an audio signal from a user. The electronic device 1 may be configured to output an audio signal to a surrounding environment and / or input an audio signal from a surrounding environment.

[0026] The electronic device 1 may include one of a pair of electronic devices configured to be placed in the left and right ears of a user. The electronic device may include a hearing device, a hearing aid, a hearing protection device, an earphone, an earplug, or a device that can block the user's ear canal. The electronic device may include an in-ear audio device or an in-ear audio device. The application or use of the electronic device 1 in the figure is for illustrative purposes only and is not intended to limit the present disclosure. For example, the electronic device may include a wearable device having a flexible portion that is configured to contact or seal a portion of the user's skin.

[0027] The electronic device 1 may include a housing 10 and an earplug sleeve 11 that can be attached to the housing 10. The housing 10 may enclose electronic components (e.g., a battery, a processor, a memory, an acoustic driver, or a source for generating an audio signal, etc.) that operate the electronic device 1. The housing 10 may include an opening 10p through which the generated audio signal can be output to the earplug sleeve 11, which can then guide the audio signal into the ear canal of the user. The earplug sleeve 11 may include an attachment structure or mechanism that enables the earplug sleeve 11 to be attached to or removed from the housing 10.

[0028] The earplug sleeve 11 may include a first portion (eg, a main body portion 111) and a second portion (eg, an earplug interface portion 112) disposed at least partially around the main body portion 111. The earplug interface portion 112 may at least partially cover the main body portion 111.

[0029] The main body portion 111 may be configured to be removably attached to the housing 10. The main body portion 111 may define or have an acoustic channel (which may also be referred to as an opening or hole) 111c, through which an audio signal (or sound wave) passes. The main body portion 111 may be configured to guide an audio signal (or sound wave). The main body portion 111 may include an acoustic input portion (which may also be referred to as an inlet) 111i, which is configured to be disposed adjacent to the opening 10p of the housing 10. The generated audio signal from the opening 10p may be received or input through the acoustic input portion 111i. The main body portion 111 may include an acoustic output portion (which may also be referred to as an outlet) 111u, which is opposite to the acoustic input portion 111i and is configured to be disposed in the ear canal of the user when the electronic device 1 is worn by the user. The main body portion 111 may include a cylindrical structure, an elliptical cylindrical structure, or a polygonal column or pillar.

[0030] When the electronic device 1 is worn by a user, the earplug interface portion 112 can form at least a partial seal with the user's ear canal (eg, Figure 6 ). The earplug interface portion 112 may be configured as a dome, or may include a spherical structure. In other arrangements, the earplug interface portion 112 may have other configurations, such as one or more radial fins.

[0031] In some arrangements, the body portion 111 and the earplug interface portion 112 can be a single unitary structure. For example, the body portion 111 and the earplug interface portion 112 can constitute an unassembled, one-piece component that can be formed in a molding or other operation. In some arrangements, the body portion 111 and the earplug interface portion 112 can constitute an assembly of separate components. For example, the earplug interface portion 112 can be adhered to at least the top end of the body portion 111 or the acoustic output portion 111u. The shape and configuration of the body portion 111 and the earplug interface portion 112 are not intended to limit the present disclosure.

[0032] In some arrangements, the main body portion 111 and the earplug interface portion 112 may each include, for example, rubber, silicon, sponge, or other suitable materials. In some arrangements, the main body portion 111 and the earplug interface portion 112 may each include liquid silicone rubber (LSR). The specific material used may depend on one or more factors, including the desire for biocompatibility and oleophobic properties, as well as other considerations and usage scenario requirements.

[0033] In some arrangements, the main body portion 111 and the earplug interface portion 112 may each include a deformable element, an adjustable element, an elastic element, a soft element and / or a flexible element. For example, the main body portion 111 and the earplug interface portion 112 may each be configured to be adjustable. For example, the main body portion 111 and the earplug interface portion 112 may each be soft enough and flexible enough for the user to wear comfortably for a long time. In some arrangements, the main body portion 111 and the earplug interface portion 112 may each be relatively more resistant to stress, impact, distortion or other physical or structural changes. For example, the main body portion 111 and the earplug interface portion 112 may each be elastic so that after being squeezed or deformed, the main body portion and the earplug interface portion may return to their original state. In some arrangements, when the electronic device 1 is worn by a user, the earplug interface portion 112 may conform to the user's ear canal. In some arrangements, the earplug interface portion 112 may flexibly adjust its shape to fit the user's ear canal.

[0034] In some arrangements, the body portion 111 and the earplug interface portion 112 may comprise the same material. In some arrangements, the body portion 111 and the earplug interface portion 112 may comprise different materials.

[0035] The earplug sleeve 11 may include a cover 110 disposed adjacent to the acoustic output portion 111u of the main body portion 111. The cover 110 may be acoustically transparent. In order for the earplug sleeve 11 to provide good quality audio, the acoustic passage 111c may be kept substantially free of any foreign matter that may collect in the acoustic passage 111c by providing the cover 110. The cover 110 may be configured to substantially prevent foreign matter, such as human body debris (e.g., earwax), from entering the acoustic passage 111c.

[0036] The cover 110 may include a mesh cover. For example, the cover 110 may include an interlaced structure or a mesh structure that allows audio signals (or sound waves) or air waves to propagate. For example, the cover 110 may be formed from a mesh of wires, threads, or yarns. For example, the cover 110 may include a plurality of openings, orifices, holes, patterns, or paths. In some arrangements, the cover 110 may include a textile, a braid, a plastic, a metal, a metal alloy, carbon fiber, silicone, other suitable materials, or a composite material. In some arrangements, the cover 110 may include a multi-layer mesh structure. In some arrangements, from a top view (e.g., Figure 2A The cover 110 may have a circular, oval, elliptical, square, triangular, polygonal, etc. profile. The multiple openings of the cover 110 may be evenly or equidistantly spaced. The multiple openings of the cover 110 may have a circular, oval, elliptical, square, triangular, polygonal, etc. profile.

[0037] Figure 2A 1 shows a top view of an electronic device according to some arrangements of the present disclosure. In some arrangements, Figure 1The earplug sleeve 11 of the electronic device 1 may have Figure 2A Top view of .

[0038] The earplug sleeve 11 may include a deformable element 20. The deformable element 20 may be encapsulated, covered, embedded and / or surrounded in the earplug sleeve 11. The deformable element 20 may not be exposed from the earplug sleeve 11. Dashed lines are shown to present the outline of the deformable element 20. The deformable element 20 may be disposed or located in the main body portion 111 and the earplug interface portion 112. The deformable element 20 may extend between the main body portion 111 and the earplug interface portion 112.

[0039] The deformable element 20 may surround or be disposed around the cover 110 and / or the main body portion 111. The deformable element 20 may be disposed adjacent to the cover 110 and / or the main body portion 111. For example, the cover 110 may be at least partially exposed from the acoustic output portion 111u, and the deformable element 20 may be disposed between the cover 110 and the outermost boundary (outer edge or outer limit) 112b of the earplug interface portion 112. The deformable element 20 may be disposed along the outermost boundary 112b of the earplug interface portion 112.

[0040] In some arrangements, the deformable element 20 may include a plurality of segments (or portions) 20s1, 20s2, 20s3, 20s4, and 20s5 disposed collectively along the outermost boundary 112b of the earplug interface portion 112. The segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 are separated from each other.

[0041] The segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may be symmetrically disposed with respect to the center of the cover 110. The segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may be spaced apart from each other by substantially equal distances.

[0042] Deformable element 20 may be deformed without experiencing cracking, rupture, or fracture. Deformation of deformable element 20 may include extension, compression, pressing, protrusion, shearing, bending, twisting, etc. For example, the size and / or shape (or dimension) of deformable element 20 may be changed from a reference configuration to a current configuration. A configuration is defined as a set of positions of all particles comprising deformable element 20. Dimensions may be measurable extents (e.g., length, breadth, depth, or height), forms, or shapes.

[0043] The deformable element 20 may be deformed (e.g., exhibit a change in size and / or shape) by an external force (e.g., stretching, pushing, shearing, bending, or twisting), a change in an electric field (or magnetic field or electromagnetic field), a change in temperature, a change in moisture content or a chemical reaction, etc. In some arrangements, the deformation of the deformable element 20 may be automatically controlled after the electronic device 1 is manufactured or manually controlled by a user.

[0044] In some arrangements, deformable element 20 may include a transducing element or transducer that can convert energy from one form to another. In some arrangements, deformable element 20 may include a vibrotactile transducer. In some arrangements, deformable element 20 may include a piezoelectric material that can exhibit a piezoelectric effect (to convert mechanical energy to electrical energy) and a converse piezoelectric effect (to convert electrical energy to mechanical energy). For example, deformable element 20 may deform when subjected to or stimulated by an electric field.

[0045] In some arrangements, the type, orientation, direction, and degree of deformation of the deformable element 20 can be controlled by the magnitude and sign of the voltage applied across the deformable element 20.

[0046] In some arrangements, when producing the electronic device 1, one or more factors may be considered and predetermined to achieve the desired deformation of the deformable element 20 (and thereby provide active noise cancellation (ANC) and enhance acoustic performance). One or more factors include different materials of the body portion 111 (with respect to Figure 4A Further description), different widths of the main body portion 111 (about Figure 4B Further description), different materials of the deformable element 20 (about Figure 4C further described) and different widths of the deformable element 20 (about Figure 4D further described).

[0047] Figure 2B 1 shows a top view of an electronic device according to some arrangements of the present disclosure. In some arrangements, Figure 1 The earplug sleeve 11 of the electronic device 1 may have Figure 2B In addition to the differences described below, Figure 2B The earplug sleeve 11 is similar to Figure 2A The earplug sleeve 11 in the embodiment of the present invention.

[0048] The earplug sleeve 11 may include a deformable element 21. The deformable element 21 may include an annular structure. The deformable element 21 may be a single unitary structure. The deformable element 21 may be deformable in a geometrically symmetrical manner and thus allow for geometrically symmetrical deformation of the earplug interface portion 112.

[0049] Figure 3AA cross-sectional view of an electronic device according to some arrangements of the present disclosure is shown. In some arrangements, Figure 1 The earplug sleeve 11 of the electronic device 1 may have Figure 3A In some arrangements, Figure 3A The cross-sectional view in Figure 2A A cross-sectional view of the earplug sleeve 11 along line AA'.

[0050] The earplug interface portion 112 may extend from the top end of the main body portion 111 or the sound output portion 111u. The earplug interface portion 112 may be at least partially separated from the main body portion 111. The space S2 between the earplug interface portion 112 and the main body portion 111 may be configured or reserved for deformation of the earplug interface portion 112 (regarding the embodiment of the present invention). Figure 6 further described).

[0051] The deformable element 20 may extend along the earplug interface portion 112. For example, the deformable element 20 may extend from the top end of the main body portion 111 or the acoustic output portion 111u to the end (or tail end) 112e of the earplug interface portion 112. The end 201 of the deformable element 20 may be closer to the acoustic output portion 111u, and the end 202 (or the opposite end) of the deformable element 20 may be closer to the end 112e of the earplug interface portion 112. The end 201 of the deformable element 20 may be covered by the main body portion 111. The end 202 of the deformable element 20 may be covered by the earplug interface portion 112. The end 202 of the deformable element 20 may extend to (or extend toward) the end 112e of the earplug interface portion 112. In some arrangements, the deformable element 20 may not be disposed in the main body portion 111. For example, the end 201 of the deformable element 20 may be spaced apart from the main body portion 111 and covered by the earplug interface portion 112.

[0052] The earplug interface portion 112 may be bonded to the deformable element 20 such that the earplug interface portion 112 may follow the movement of the deformable element 20. The earplug interface portion 112 may be bonded to the deformable element 20 such that when the deformable element 20 is deformed (e.g., exhibits a change in size and / or shape), the size and / or shape of the earplug interface portion 112 may change along the deformable element 20.

[0053] In some arrangements, deformable element 20 may be configured to receive a signal (which may include a control signal from electronic component 30 or an instruction from a user) and deform (e.g., exhibit a change in size and / or shape) based on the signal. For example, deformable element 20 may be configured to deform automatically or manually after being manufactured.

[0054] In some arrangements, the deformable element 20 may be configured to deform, move, apply force, or push the earplug interface portion 112 based on the signal. For example, the deformable element 20 may be configured to change the size, shape, or both of the earplug interface portion 112 based on the signal. For example, the deformable element 20 may be configured to make the earplug interface portion 112 conform to (or fit, seal) the user's ear canal based on the signal.

[0055] For example, deformable element 20 may be configured to automatically or manually deform earplug interface portion 112 after being manufactured. For example, deformable element 20 may be configured to automatically or manually conform earplug interface portion 112 to (or fit, seal) the user's ear canal after being manufactured.

[0056] In some arrangements, the earbud sleeve 11 may include a user device to provide manually operable control of the deformable element 20. The user device may include any device capable of communicating via a network, such as a home network and / or an access network. The user device may include an interactive interface, such as a graphical user interface (GUI). Examples of user devices may include a mobile phone, a tablet, a personal computer, or another device that can provide the ability to selectively deform the deformable element 20. For example, the user device may provide multiple modes for the user to select from.

[0057] In some arrangements, the earplug sleeve 11 may include an electronic component 30. The electronic component 30 may include a system-in-package (SiP). In some arrangements, the electronic component 30 may include a control component (or control unit), a data conversion component, a processing component, a storage component, a transmission component, or a combination thereof. In some arrangements, the electronic component 30 may include an analog-to-digital converter.

[0058] In some arrangements, the electronic assembly 30 may be configured to control the deformation of the deformable element 20. In some arrangements, the electronic assembly 30 may be configured to control the size and / or shape of the deformable element 20. In some arrangements, the electronic assembly 30 may be configured to control the size and / or shape of the earplug interface portion 112 by deforming the deformable element 20.

[0059] For example, the electronic component 30 may be configured to provide a control signal (e.g., a voltage) to the deformable element 20 (which may include a piezoelectric material). The type (e.g., extension, compression, depression, protrusion, shearing, bending, twisting, etc.), orientation, direction, and degree of deformation of the deformable element 20 may be controlled by the magnitude and sign of the voltage applied from the electronic component 30 across the deformable element 20. In some arrangements, the electronic component 30 may be configured to automatically control the deformation of the deformable element 20 (with respect to Figure 5A further described).

[0060] In some arrangements, the electronic component 30 may generate control signals to the deformable element 20 (which may be a vibrotactile transducer) to generate an oscillatory motion (periodic motion) of the deformable element 20 (and the earplug interface portion 112) and provide an alarm or vibrotactile stimulus to the user. In some arrangements, the electronic component 30 may generate control signals to the deformable element 20 to generate non-periodic motion including, but not limited to, deformation, such as extension, compression, depression, protrusion, shearing, bending, twisting, etc.

[0061] In some arrangements, electronic assembly 30 may be configured to automatically control the vibration or deformation of deformable element 20. For example, electronic assembly 30 may be configured to receive a signal from another detector, such as an incoming call on a cell phone, a verbal or non-verbal command issued by a user, and / or an activity of the user. The activity of the user may include movement, such as movement of the user's head, movement of the user's eyes, and movement of the user's body.

[0062] The electronic component 30 may be placed on the carrier 30c. The electronic component 30 may be electrically connected to one or more of the other electrical components (if present), to the carrier 30c, and to the deformable element 20, and the electrical connection may be achieved by means of flip chip or wire bonding technology. The carrier 30c may be, for example, a printed circuit board, such as a paper copper foil laminate, a composite copper foil laminate, or a polymer impregnated fiberglass copper foil laminate. In some arrangements, the carrier 30c may include interconnect structures, such as a redistribution layer (RDL), a ground layer, and a feed line. In some arrangements, the carrier 30c may include one or more conductive pads (not shown in the figure) close to, adjacent to, or embedded in a surface 30c1 of the carrier 30c and exposed at the surface. The carrier 30c may include a solder resist (or solder mask) (not shown in the figure) on the surface 30c1 of the carrier 30c to fully expose the conductive pads or expose at least a portion of the conductive pads for electrical connection.

[0063] The electronic component 30 and the carrier 30c may be electrically connected to the deformable element 20 via a flexible connection element 30f. In some arrangements, the flexible connection element 30f may include an electrical connection element, such as a flexible printed circuit (FPC), a conductive wire, a redistribution layer (RDL), or a combination thereof. In some arrangements, the flexible connection element 30f may extend along the acoustic channel 111c. In some arrangements, the flexible connection element 30f may extend along the main body portion 111. In some arrangements, the flexible connection element 30f may extend from the carrier 30c to the top of the main body portion 111 or the acoustic output portion 111u. In some arrangements, the flexible connection element 30f may contact or be connected to the end 201 of the deformable element 20.

[0064] The electronic component 30 may be covered by an encapsulation layer 30e. The encapsulation layer 30e may be disposed on the carrier 30c to encapsulate the electronic component 30. The encapsulation layer 30e may be disposed on the opposite side of the carrier 30c. The encapsulation layer 30e may surround the edge of the electronic component 30 and may further cover the active surface and / or the inactive surface of the electronic component 30.

[0065] The encapsulation layer 30e may cover a portion of the flexible connection element 30f. The flexible connection element 30f may extend through the encapsulation layer 30e and the body portion 111 to connect to the deformable element 20. The encapsulation layer 30e may include epoxy resin with fillers, a molding material (e.g., an epoxy molding material or another molding material), a polyimide, a phenolic compound or material, a material having silicone dispersed therein, or a combination thereof.

[0066] In some arrangements, the electronic component 30 may be integrated into the earplug sleeve 11 (e.g., by an insert molding process) to shorten the flexible connection element 30f and reduce the transmission distance of the control signal from the electronic component 30 to the deformable element 20 through the flexible connection element 30f. For example, the electronic component 30 may be at least partially disposed in the body portion 111. For example, the electronic component 30 may be at least partially disposed in the earplug interface portion 112. In some arrangements, the electronic component 30 may be integrated into an attachment structure or mechanism that enables the earplug sleeve 11 to be attached to or removed from the housing 10.

In addition to the electronic component 30 and the carrier 30c being disposed in the housing 10, Figure 3B The earplug sleeve 11 is similar to Figure 3A The earplug sleeve 11 in the housing 10. The opening 10p through which the generated audio signal can be output is arranged in the sound channel 111c. By arranging the electronic component 30 and the carrier 30c in the housing 10, the electronic component 30 and the carrier 30c can be easily replaced and maintained.

For example, at least two of the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 have different sizes and / or shapes. For example, at least two of the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 have different profiles. For example, a voltage may be applied to the segment 20s2 to deform the segment 20s2. The segment 20s2 may be geometrically different from the other segments of the deformable element 20. In the embodiment, at least two of the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 have different sizes and / or shapes. For example, at least two of the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 have different profiles. For example, a voltage may be applied to the segment 20s2 to deform the segment 20s2. The segment 20s2 may be geometrically different from the other segments of the deformable element 20. Figure 3C In the embodiment, the segment 20s2 can move away from the main body portion 111 and can expand outwardly the outermost boundary 112b of the earplug interface portion 112. The space S2 between the earplug interface portion 112 and the main body portion 111 can be enlarged.

[0071] In a comparative arrangement, to enable an electronic device (e.g., an in-ear audio device or an in-ear audio device) to be used with ears of different sizes and shapes, one solution is to provide a range of earbud sleeves of different shapes and / or sizes from which a user can select. Despite the known solutions, there remains a need to provide a proper fit with the user's ear canal to provide active noise cancellation (ANC) and enhance acoustic performance when the electronic device is comfortably in place.

[0072] By providing a deformable element 20 in the earplug interface portion 112 to allow automatic deformation or manual deformation of the earplug interface portion 112, the size and / or shape of the earplug interface portion 112 can be adjusted and modified to automatically or manually provide a proper fit with the user's ear canal after the electronic device is manufactured. For example, the size and / or shape of the earplug interface portion 112 can be automatically or manually adjusted and modified to remain against the user's ear canal without impairing movement or causing discomfort. In addition, the earplug interface portion 112 can form a desired degree of seal (or compliance) with the user's ear canal, which in turn can increase the convergence speed and improve active noise cancellation (ANC) performance. Therefore, the desired acoustic performance can be achieved and the user experience can be enhanced.

[0073] The number of segments of deformable element 20 may be 2, 3, 4, 5, 6, 7, 8, or more. More segments of deformable element 20 allow for more accurate control of the deformation of earplug interface portion 112. For example, earplug interface portion 112 may expand or contract along different directions. For example, earplug interface portion 112 may expand or contract along multiple directions.

[0074] For example, the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may each be independently controlled. For example, the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may each be configured to receive a signal (which may include a control signal from the electronic component 30 or an instruction from a user) and deform independently. Therefore, the type (e.g., extension, compression, pressing, protrusion, shearing, bending, twisting, etc.), orientation, direction, and degree of deformation of the deformable element 20 may be more accurately controlled.

[0075] Figure 4A 1 shows a cross-sectional view of an electronic device according to some arrangements of the present disclosure. In addition to the main body portion 111 including a portion 111a connected to the earplug interface portion 112 and a portion 111b connected to the portion 111a, Figure 4A The earplug sleeve 11 is similar to Figure 3A The earplug sleeve 11 in the embodiment of the present invention. The portion 111a can be connected between the earplug interface portion 112 and the portion 111b. The portion 111a can cover or enclose the end 201 of the deformable element 20.

[0076] Portion 111b and earplug interface portion 112 may comprise the same material. Portion 111b and earplug interface portion 112 may share the same characteristics or properties. For example, portion 111b and earplug interface portion 112 may have substantially the same elasticity, ductility, and / or expandability.

[0077] Portion 111a may have characteristics or properties that are different from those of portion 111b. For example, portion 111b may be softer than portion 111a. Portion 111b may have greater elasticity than portion 111a. Portion 111b may have greater ductility than portion 111a. Portion 111b may have greater ductility than portion 111a. Portion 111b may have greater ductility than portion 111a.

[0078] For example, part 111a may be harder than part 111b. The hardness of part 111a may be greater than the hardness of part 111b. The ductility of part 111a may be less than the ductility of part 111b. The ductility of part 111a may be less than the ductility of part 111b. The ductility of part 111a may be less than the ductility of part 111b. Part 111a may include rubber, such as thermosetting rubber or hard rubber, or other hard materials. In some arrangements, part 111a may be or include silicon (Si), glass or other suitable materials. Parts 111a and 111b may be formed using a two-step molding process.

[0079] Portion 111a may constrain or limit the deformation of deformable element 20. For example, end 202 of deformable element 20 may be a relatively free end (or an end that can be deformed more easily), and end 201 of deformable element 20 may be a relatively fixed end (or an end that is more difficult to deform). Thus, end 202 of deformable element 20 may be deformed to allow for more accurate control of the deformation of earplug interface portion 112, while end 201 of deformable element 20 is substantially fixed. The overall shape and appearance of earplug sleeve 11 and cover 110 may be maintained by portion 111a, so that ventilation of acoustic channel 111c is unchanged (e.g., transmission of audio signals (or sound waves) and air waves through the plurality of openings of cover 110 is not adversely affected), while at the same time, earplug interface portion 112 may move to fit with the ear canal of the user.

[0080] In some arrangements, portion 111a may comprise the top end of body portion 111, such as Figure 4A In some arrangements, portion 111a may be spaced apart from the top of body portion 111 to improve wearing comfort. For example, portion 111a may cover end 202 of deformable element 20, and portion 111b (or another flexible element) may cover portion 111a.

[0081] Figure 4B 1 shows a cross-sectional view of an electronic device according to some arrangements of the present disclosure. In addition to the width 111aw of portion 111a being greater than the width 111bw of portion 111b, Figure 4B The earplug sleeve 11 is similar to Figure 4A The earplug sleeve 11 in the embodiment of the present invention. The portion 111a and the portion 111b may comprise the same material. In some arrangements, the portion 111a and the portion 111b may comprise different materials, such as Figure 4A The overall shape and appearance of the earplug sleeve 11 and the cover 110 can be maintained by the portion 111a so that the ventilation of the acoustic channel 111c is unchanged (e.g., the transmission of audio signals (or sound waves) and air waves through the multiple openings of the cover 110 is not adversely affected), while at the same time, the earplug interface portion 112 can be moved to fit the user's ear canal.

[0082] Similar to Figure 4A , portion 111a having a larger width may constrain or limit the deformation of deformable element 20. Thus, end 202 of deformable element 20 may be deformed to allow for more accurate control of the deformation of earplug interface portion 112, while end 201 of deformable element 20 is substantially fixed.

[0083] Figure 4C 1 shows a cross-sectional view of an electronic device according to some arrangements of the present disclosure. In addition to the deformable element 20 including a portion 20a and a portion 20b connected to the portion 20a, Figure 4CThe earplug sleeve 11 is similar to Figure 3A The portion 20a is disposed closer to the top of the main body portion 111 or the sound output portion 111u than the portion 20b. The portion 20b is disposed closer to the end 112e of the earplug interface portion 112 than the portion 20a.

[0084] Portion 20a may have characteristics or properties that are different from those of portion 20b. For example, portion 20b may be softer than portion 20a. Portion 20b may have a greater elasticity than portion 20a. Portion 20b may have a greater ductility than portion 20a. Portion 20b may have a greater ductility than portion 20a. Portion 20b may have a greater ductility than portion 20a.

[0085] For example, portion 20a may be stiffer than portion 20b. The stiffness of portion 20a may be greater than the stiffness of portion 20b. Portions 20a and 20b of deformable element 20 may each include a piezoelectric material, which may be crystalline, ceramic, or polymeric. In some arrangements, portion 20b may deform to a greater extent than portion 20a. For a voltage applied across deformable element 20, the response of portion 20b may be greater than the response of portion 20a.

[0086] End 202 of deformable element 20 may be a relatively free end (or an end that can be deformed more easily), and end 201 of deformable element 20 may be a relatively fixed end (or an end that is more difficult to deform). Thus, end 202 of deformable element 20 may be deformable to allow for more accurate control of the deformation of earplug interface portion 112, while end 201 of deformable element 20 is substantially fixed.

[0087] Figure 4D 2 shows a cross-sectional view of an electronic device according to some arrangements of the present disclosure. In addition to the width 20aw of portion 20a being greater than the width 20bw of portion 20b, Figure 4D The earplug sleeve 11 is similar to Figure 4C The earplug sleeve 11 in the embodiment of the present invention. The portion 20a and the portion 20b may comprise the same material. In some arrangements, the portion 20a and the portion 20b may comprise different materials, such as Figure 4C as shown in .

[0088] Similar to Figure 4C , the end 202 of the deformable element 20 can be a relatively free end. Therefore, the end 202 of the deformable element 20 can be deformed to allow more accurate control of the deformation of the earplug interface portion 112, while the end 201 of the deformable element 20 is substantially fixed.

[0089] Figure 5A 1 shows a top view of an electronic device according to some arrangements of the present disclosure. In some arrangements, Figure 1The earplug sleeve 11 of the electronic device 1 may have Figure 5A In addition to the differences described below, Figure 5A The earplug sleeve 11 is similar to Figure 2A The earplug sleeve 11 in the embodiment of the present invention.

[0090] At least one of the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 includes a sensing element or a detection element. For example, the segments 20s2 and 20s5 may generate a signal as an indication of the degree of seal between the earplug interface portion 112 and the user's ear canal. For example, the segments 20s2 and 20s5 include a piezoelectric material and may generate an electrical charge in response to an applied mechanical stress, such as a force from the user's ear canal when the earplug interface portion 112 expands to press against the user's ear canal.

[0091] Electronic assembly 30 may be configured to use signals from segments 20s2 and 20s5 as feedback to automatically control the deformation of deformable element 20 .

[0092] For example, the feedback process may include at least the following stages (or steps): The first stage involves the electronic component 30 generating a signal (a first signal, such as a voltage) to the segments 20s1, 20s3, and 20s4 to expand the earplug interface portion 112. The segments 20s2 and 20s5 may contact or press against the user's ear canal.

[0093] The second stage involves sections 20s2 and 20s5 generating a signal (a second signal, eg, a voltage) to the electronics assembly 30 as an indication of the degree of seal between the earbud interface portion 112 and the user's ear canal.

[0094] The third stage involves the electronics assembly 30 using the signals from sections 20s2 and 20s5 as feedback to determine whether the desired degree of sealing has been achieved.

[0095] The fourth stage involves the electronic assembly 30 generating a signal (a third signal, such as a voltage) to the segments 20s1, 20s3, and 20s4 based on the determination. In some arrangements, the third signal may include a sign opposite to that of the first signal to adjust the deformation. The opposite sign may include both positive and negative signs. In some arrangements, the third signal may include a command to stop the deformation of the segments 20s1, 20s3, and 20s4.

[0096] The process can be repeated until the desired degree of sealing between the earplug interface portion 112 and the user's ear canal is achieved. The order, timing, duration, and priority of the steps are not intended to be limited. For example, the process can start from the second stage.

[0097] The positions, functions, and numbers of the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 in the earplug sleeve 11 are not intended to limit the present disclosure. For example, any number of segments may be used to provide feedback, depending on design requirements. For example, the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may each be configured to provide feedback. For example, the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may each be configured to deform to contact or press against the user's ear canal and generate a signal to the electronic component 30. For example, the segments 20s1, 20s2, 20s3, 20s4, and 20s5 of the deformable element 20 may each be configured to partially deform the deformable element 20 and generate a feedback signal. For example, segments 20s1, 20s2, 20s3, 20s4, and 20s5 of deformable element 20 may each be configured to be multifunctional. For example, segments for providing feedback may be evenly or equidistantly spaced to allow for more accurate control of the deformation of deformable element 20.

[0098] Figure 5B 1 shows a top view of an electronic device according to some arrangements of the present disclosure. In some arrangements, Figure 1 The earplug sleeve 11 of the electronic device 1 may have Figure 5B In addition to the replacement of segments 20s2 and 20s5 with sensing elements 50 and 51, Figure 5B The earplug sleeve 11 is similar to Figure 5A The earplug sleeve 11 in the embodiment of the present invention.

[0099] In some arrangements, sensing elements 50 and 51 may each be an electrode, a thermistor, a pressure sensor, a proximity sensor, a motion sensor, an acoustic sensor, an odor sensor, a particle sensor, a humidity sensor, an optical transmitter, an optical receiver, an optical transceiver, or a combination thereof.

[0100] In some arrangements, the sensing elements 50 and 51 can each be used to detect or collect one or more signals or information external to the earplug sleeve 11. For example, the sensing elements 50 and 51 can be used to detect temperature, air pressure, smell, particles, sound, light, humidity, or other environmental variables. For example, the sensing elements 50 and 51 can be used to generate a signal indicative of the environmental variable.

[0101] In some arrangements, electronic assembly 30 may be configured to use signals from sensing elements 50 and 51 as feedback to automatically control the deformation of deformable element 20 .

[0102] In some arrangements, the earbud sleeve 11 may include sensing elements 50 and 51 (to generate a signal as an indication of an environmental variable) and a sensing segment (e.g., Figure 5A The signals from the sensing elements 50 and 51 and from the sensing segments (e.g., Figure 5A The signals of sections 20s2 and 20s5) in the deformable element 20 can be used as feedback for the electronic component 30 to automatically control the deformation of the deformable element 20.

[0103] Figure 5C A cross-sectional view of an electronic device according to some arrangements of the present disclosure is shown. In some arrangements, Figure 1 The earplug sleeve 11 of the electronic device 1 may have Figure 5C In some arrangements, Figure 5C The cross-sectional view in Figure 5B A cross-sectional view of the earplug sleeve 11 along line BB'.

[0104] The sensing element 51 may be partially exposed from the earbud interface portion 112. In some arrangements, the sensing element 51 may be partially surrounded, embedded, or covered by the earbud interface portion 112. However, in some arrangements, the sensing element 51 may be completely embedded in the earbud interface portion 112.

[0105] Figure 6 A side view of an ear-worn electronic device 1 is shown according to some arrangements of the present disclosure.

[0106] When the electronic device 1 is worn by the user, the deformable element 20 may be deformed (e.g., exhibit a change in size and / or shape), and the size and / or shape of the earplug interface portion 112 follows the size and / or shape of the deformable element 20 to conform to (or fit, seal) the user's ear canal. For example, the earplug interface portion 112 may separate the space (or internal space or first space) S1 of the user's ear canal from the space (or second space) S2 between the earplug interface portion 112 and the main body portion 111. Since the space S2 is predefined between the earplug interface portion 112 and the main body portion 111, the earplug interface portion 112 may be deformed while being comfortably in place.

[0107] As used herein, the singular forms "a," "an," and "the" may include plural or plural referents unless the context clearly indicates otherwise.

[0108] As used herein, the terms "conductive," "electrically conductive," and "conductivity" refer to the ability to carry an electric current. Conductive materials are materials that present little or no resistance to the flow of electric current. One unit of measurement for conductivity is Siemens per meter (S / m). Typically, a conductive material is one that has a conductivity greater than about 10 4 S / m, for example at least 10 5 S / m or at least 10 6 S / m of a material. The conductivity of a material sometimes varies with temperature. Unless otherwise specified, the conductivity of a material is measured at room temperature.

[0109] As used herein, the terms "approximately," "substantially," "generally," "about," and "about" are used to describe and explain minor variations. When used in conjunction with an event or circumstance, these terms may refer to instances where the event or circumstance occurred exactly as well as instances where the event or circumstance occurred very approximately. For example, when used in conjunction with a numerical value, these terms may refer to a range of variation of less than or equal to ±10% of the numerical value, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%. For example, if the difference between two numerical values ​​is less than or equal to ±10% of the average of these values, such as less than or equal to ±5%, less than or equal to ±4%, less than or equal to ±3%, less than or equal to ±2%, less than or equal to ±1%, less than or equal to ±0.5%, less than or equal to ±0.1%, or less than or equal to ±0.05%, then the two numerical values ​​may be considered to be "substantially" the same or equal. For example, "substantially" parallel can refer to an angle range of less than or equal to ±10° relative to 0°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°. For example, "substantially" perpendicular can refer to an angle range of less than or equal to ±10° relative to 90°, such as less than or equal to ±5°, less than or equal to ±4°, less than or equal to ±3°, less than or equal to ±2°, less than or equal to ±1°, less than or equal to ±0.5°, less than or equal to ±0.1°, or less than or equal to ±0.05°.

[0110] In addition, amounts, ratios and other numerical values ​​are sometimes presented herein in a range format. It should be understood that such a range format is used for the sake of convenience and brevity, and should be flexibly construed to include not only the values ​​explicitly specified as the limits of the range, but also all individual values ​​or sub-ranges encompassed within the range, as if each value and sub-range were explicitly specified.
