Description

Technical Field

[0001] This utility model relates to the field of head-mounted smart device technology, and in particular to an ear support for a head-mounted smart device and the head-mounted smart device itself. Background Technology

[0002] In existing smart glasses, the front frame and temples are typically fixed as a single unit. The temples house core components such as circuit boards, batteries, and speakers to convert sound into electroacoustic signals. Because the sound outlet must be located near the ear, and given the limited internal space and consumer requirements regarding the size of the glasses, current technology lacks suitable cavities for audio components. The speaker is crampedly placed near the sound outlet, resulting in a dry and monotonous sound, affecting the quality and richness of the sound waves and leading to poor audio quality.

[0003] The above background information is provided only to aid in understanding the concept and technical solution of this utility model. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above information was disclosed on the filing date of this patent application, the above background information should not be used to evaluate the novelty and inventiveness of this application.

[0037] The embodiments of this utility model are described in detail below. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of this utility model.

[0038] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as "connected to" another component, it can be directly connected to or indirectly connected to that other component. Furthermore, a connection can be used for both fixing and circuit / signal connectivity.

[0039] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0042] Example 1 like Figure 1 As shown, a preferred embodiment of this utility model discloses an ear support 100 for a head-mounted smart device, including a shell 10, a sound guiding cavity 20, a sound outlet 30, and a sound-producing device. The sound-producing device is disposed on the shell 10 at a position corresponding to the back of the wearer's auricle, and the sound outlet 30 is opened on the shell 10 at a position corresponding to the front of the wearer's auricle. The sound guiding cavity 20 is disposed between the sound-producing device and the sound outlet 30 to connect the sound-producing device and the sound outlet 30, and at least one sound wave reflector 21 is provided on the inner wall of the sound guiding cavity 20.

[0043] In some embodiments, the ear support 100 of the head-mounted smart device is, for example, the temple of an audio glasses.

[0044] For example, the outer shell 10 is provided with a bent portion 11, which corresponds to the position directly above the wearer's auricle. The sound-producing device is, for example, a horn. The horn 40 is located behind the bent portion 11 and at the rear end of the sound guide cavity 20, that is, at one end near the tail of the ear support. The front end of the sound guide cavity 20 is connected to the sound outlet 30. At least one sound wave reflector 21 protruding relative to the inner wall of the sound guide cavity 20 is provided inside the sound guide cavity 20.

[0045] Typically, ear supports placed on the auricle are relatively small in size, resulting in a cramped internal space. Therefore, existing technologies usually try to make full use of all the space and fill all the empty spaces. However, the ear support proposed in the preferred embodiment of this utility model does the opposite, deliberately leaving a cavity and leaving a certain distance between the speaker and the sound outlet. This not only gets rid of the limitation on the speaker position, but also allows the cavity to be used as a resonant cavity, improving the sound effect, especially the low-frequency sound effect, thereby ultimately resolving the contradiction between the miniaturization of the acoustic cavity and the sound field quality.

[0046] Combination Figure 2 and Figure 3In some embodiments, sound wave reflectors 21 protrude from at least two opposing side walls of the inner wall of the sound-guiding cavity 20. For example, the inner wall of the sound-guiding cavity 20 includes an upper wall 22 and a lower wall 23 disposed opposite to each other, and a first side wall 24 and a second side wall 25 disposed opposite to each other. For example, the first side wall 24 is the inner wall of the housing 10, and the second side wall 25 is, for example, the inner wall of a cover that separately covers the sound-guiding cavity 20. Sound wave reflectors 21 protrude from at least two opposing side walls of the upper wall 22, lower wall 23, first side wall 24, and second side wall 25. For example, sound wave reflectors 21 protrude from the upper wall 22 and lower wall 23 disposed opposite to each other, and / or from the first side wall 24 and second side wall 25 disposed opposite to each other. The side walls of the sound-guiding cavity 20 may be, but are not limited to, arc-shaped, which allows for better modulation of the sound waves.

[0047] The acoustic wave reflector 21 is a multi-directional reflective surface structure protruding from the inner wall of the sound-guiding cavity 20. The multi-directional reflective surface structure has at least two reflective surfaces in different directions. Further, the multi-directional reflective surface structure includes at least one of a reflective prism, a reflective pyramid, and a reflective arc surface. For example, in some embodiments, the inner wall of the sound-guiding cavity 20 is provided with a shape of one of the reflective prism, a reflective pyramid, and a reflective arc surface; in other embodiments, the inner wall of the sound-guiding cavity 20 may also be provided with a combination of two or three of the reflective prism, a reflective pyramid, and a reflective arc surface.

[0048] See again Figure 1 The multi-directional reflective surface structure includes a reflective prism, wherein the side length of the surface of the reflective prism protruding relative to the inner wall of the sound guiding cavity 20 is 2.5mm~3.5mm, that is, the width of the reflective prism is 2.5mm~3.5mm. The width of the reflective prism represents the length of the side protruding relative to the inner wall of the sound guiding cavity. Two adjacent reflective prisms are seamlessly connected, and the angle formed by two adjacent reflective prisms is 100°~150°, preferably 128°.

[0049] See again Figure 2 The multi-directional reflective surface structure includes a reflective arc surface, wherein the arc length of the reflective arc surface is 15mm~17mm, preferably 16mm; the interval between two adjacent reflective arc surfaces is 7mm~7.5mm, preferably 7.3mm; the height of the top of the reflective arc surface protruding from the inner wall of the sound guiding cavity 20 is 1.4mm~1.6mm, preferably 1.5mm, that is, the height of the top of the reflective arc surface is 1.4mm~1.6mm, preferably 1.5mm. The height of the top of the reflective arc surface represents the distance between the top of the reflective arc surface and the inner wall on which the reflective arc surface is located. For example, if the reflective arc surface protrudes from the upper wall 22, the height of the top represents the vertical distance between the top of the reflective arc surface and the upper wall 22.

[0050] See again Figure 3The multi-directional reflective surface structure includes reflective pyramids, with multiple reflective pyramids arranged in an array. For example, multiple columns of reflective pyramids can be arranged along the direction of sound wave propagation, with each column including multiple reflective pyramids, for the optimization of sound wave reflection and propagation.

[0051] In some embodiments, the ear support of the head-mounted smart device further includes electronic components. A receiving cavity 12 is provided inside the housing 10 on the side of the speaker 40 away from the sound guide cavity 20, and the electronic components are disposed within the receiving cavity 12. The electronic components include, but are not limited to, one or more of a Bluetooth module, an artificial intelligence module, a wireless WIFI module, an NFC module, or a circuit board, wherein some or all of the Bluetooth module, artificial intelligence module, wireless WIFI module, and NFC module are located on the circuit board.

[0052] refer to Figure 4 In some embodiments, the outer casing 10 has a first opening 14 (i.e., an opening) and a positioning cavity 13 at the end of the sound guide cavity 20 away from the speaker 40. The first opening 14 communicates with the positioning cavity 13, which contains a positioning component 131. The positioning component 131 is used to cooperate with a connector component 201 on the external bracket 200 (e.g., external eyeglass temples) to allow the ear bracket 100 to be repeatedly and manually detachably connected to the external bracket 200. The positioning component 131 can be, but is not limited to, a positioning bead, a snap fastener, a thread, a pin, a magnetic component, etc. Correspondingly, the connector component 201 can be, but is not limited to, a groove, a thread, a magnetic matching component, etc. Alternatively, the positioning component 131 can be one or more combinations of positioning beads, snap fasteners, threads, pins, etc. The positioning bead can be, but is not limited to, a diameter of 3.0 mm * a length of 3.0 mm, with an elastic force of 10 N; the snap fastener can be, but is not limited to, a length of 3.0 mm * a width of 3.0 mm * a height of 1.5 mm, with a locking force of 10 N. The number of positioning beads is unlimited; there can be one, two, or more. The number of buckles is also unlimited; there can be one, two, or more. A limiting component 132 is provided after the positioning cavity 13. The limiting component, such as a limiting block or a limiting post, can limit the external bracket 200 at the front end to prevent it from falling off the positioning component 131.

[0053] This invention utilizes a sound guide cavity 20 to transmit sound waves from a speaker 40 to a sound outlet 30. The speaker 40 is positioned at a certain distance from the sound outlet 30, allowing the narrow space at the sound outlet 30 to be reused as the sound guide cavity 20. The inner wall of the sound guide cavity 20 is used to fine-tune the sound waves from the speaker. Furthermore, a sound wave reflector 21 is installed on the inner wall of the sound guide cavity 20 to improve the sound wave reflection path and adjust the sound wave reflection. These two adjustments enhance the sound effect, enriching the audio quality.

[0054] refer to Figure 5Another preferred embodiment of this utility model discloses a smart glasses, including an eye socket component 400, a temple 300, and an ear support 100. For example, the eye socket component 400 and the temple 300 form a glasses frame. The temple 300 can be fixedly connected to the eye socket component 400, and the ear support 100 can be repeatedly detached and reconnected to the temple 300 by hand. For example, the structure of the temple 300 is equivalent to... Figure 4 The external support 200 of the ear bracket 100 is provided with a connector component 201 structure, which can be inserted into the positioning cavity 13 through the first opening 14 at the front end of the outer shell 10 of the ear bracket 100, and is adapted to the positioning component 131 to achieve a tight fit connection. In some embodiments, the ear bracket 100 may be less than or equal to 1 / 2 of the length of the temple formed by the temple 300 of the glasses and the ear bracket 100, for example, the ear bracket 100 is 1 / 3 of the length of the temple, or the length of the ear bracket 100 is 8~13cm. In some embodiments, the smart glasses are, for example, audio glasses, which include a frame and audio temples. The frame includes a lens frame and a front temple. One end of the front temple is connected to the lens frame, and the other end of the front temple passes through the opening of the audio temple. The second positioning component is engaged with the first positioning component in the positioning cavity.

[0055] In other embodiments, the ear support 100 can also be used in other head-mounted smart devices, such as smart helmets, AR head-mounted displays, and headphones. The head-mounted smart device includes a device body, an external support, and the ear support 100. The external support is connected to the device body, and a connector is provided at the free end of the external support so that it can be inserted from the first opening of the outer shell and cooperate with the positioning component to form a stable connection structure, thereby improving the comfort of the head-mounted smart device when worn on the ear.

[0056] In practical operation, the sound waves emitted by the speaker 40 pass through the sound guide cavity 20 and are subject to dual adjustment by the inner wall of the sound guide cavity 20 and the sound wave reflector 21 set in the sound guide cavity 20, thereby increasing the richness of the sound wave reflection path and improving the audio quality.

[0057] The beneficial effects of adding the sound wave reflector 21 in this embodiment are analyzed as follows: Firstly, it can enhance low-frequency reflection and standing wave control; (1) Extend the reflection path of low-frequency sound waves Principle: Low-frequency sound waves have relatively long wavelengths (e.g., 20Hz corresponds to approximately 17 meters), and are easily attenuated in small sound cavities (such as headphones and speakers) due to insufficient cavity size. The sound wave reflector 21 changes the direction of sound wave propagation, causing low-frequency sound waves to be reflected multiple times within the sound guide cavity 20, extending their residence time, thereby improving the utilization rate of low-frequency energy.

[0058] Effect: Increased loudness and depth of low frequencies (such as 20Hz~100Hz), making the sound "full" and "powerful".

[0059] (2) Suppressing low-frequency standing waves Principle: When sound waves are reflected between the two parallel interfaces of the sound guiding cavity 20, standing waves are formed (vibrations at a fixed position are strengthened or weakened), resulting in low-frequency distortion (such as a "humming sound"). The non-parallel surface of the sound wave reflector 21 can disrupt the regularity of the standing waves, making the sound wave energy distribution more uniform.

[0060] Effects: Reduced low-frequency muddiness and improved clarity.

[0061] Secondly, it can optimize mid-to-high frequency diffusion and directivity: (1) Scattering high-frequency sound waves to reduce phase interference Principle: Mid-to-high frequency sound waves have shorter wavelengths (e.g., 10kHz corresponds to approximately 3.4cm wavelength), and the diffraction at the edge of the sound guide cavity 20 causes phase interference (e.g., a comb-like filtering effect). The multifaceted structure of the sound wave reflector 21 can scatter concentrated mid-to-high frequency sound waves in multiple directions, avoiding frequency response peaks and valleys caused by strong reflection in a single direction.

[0062] Effects: The frequency response curve in the mid-to-high frequencies (such as 2kHz~5kHz) is smoother, sibilance or harshness is reduced, and the details of vocals and instruments are more natural.

[0063] (2) Adjust the sound field directivity Principle: The angle and position of the sound wave reflector 21 can guide the sound waves to diffuse in a specific direction (such as towards the ear in headphones), avoiding energy loss caused by the "random reflection" of sound waves in the cavity.

[0064] Effect: The stereoscopic and positioning effects of the sound field are enhanced, especially in open-cavity designs, where the "spatial" sound is closer to the real environment.

[0065] Example 2 This embodiment focuses on the positioning and limiting components within the first cavity, wherein the positioning component employs magnetic positioning, such as... Figure 6-1As shown, the positioning component is a magnetic base 312, which cooperates with the magnetic head 322 on the external connector for positioning through attraction (hereinafter referred to as the interface structure). The magnetic base includes a cylindrical or disc-shaped magnet embedded or bonded to the limiting component. The magnetic base is disposed on the limiting component, and the attraction surface of the magnetic base is the positioning surface, which is perpendicular to the insertion path direction; thus, the detachable earpiece leg is configured to cooperate with the external connector to achieve a single-handed, repeated insertion and removal connection. The magnetic force level of the magnetic base is between N42 and N55, preferably N52; the magnetic base is cylindrical, with a length of 4-6mm, preferably 5mm, of which 1-3mm, preferably 1.5mm, is embedded in the interface component body, and the exposed portion is 2-5mm, preferably 3.5mm, with a cross-sectional area of ​​12-79mm², preferably 28.3mm², and a diameter of 2-5mm, preferably 3mm. Its exposed end face is the attraction surface. In the diagram, 400 represents the front frame of the glasses; 300 represents the temples (front temples); and 100 represents the ear support body. The detachable ear support is thus configured to mate with an external connector, enabling repeated linear insertion and removal with one hand without overcoming sidewall friction, reducing wear and allowing for more insertion and removal cycles. The limiting component is used to restrict the insertion depth of the pluggable external connector, limiting the depth to which the external connector can be inserted after exceeding the positioning depth of the positioning component, or to limit the degree of backward displacement of the positioning component caused by the impact of the external connector insertion.

[0066] Figure 6-2 This is a breakdown diagram of the interface structure. Figure 6-3 This is an exploded view of the detachable temple interface assembly. Magnets 314 are provided inside both the magnetic base 312 and the magnetic head 322.

[0067] The guide cavity 313 has a square or flat cross-section in at least a portion of its length. This prevents the connector assembly from rotating during insertion; thus, the detachable earpiece leg is configured to engage with an external connector to achieve a single-handed, repetitive linear insertion and removal connection, while limiting wobbling or swinging during insertion and removal.

[0068] The distance for the external connector to move within the guide cavity is less than 7mm, thus the detachable earpiece legs are configured to cooperate with the external connector to achieve a single-handed, repetitive linear plug-and-play connection, while limiting wobbling or swinging during plugging and unplugging.

[0069] Preferably, the magnetic head 322 has a magnetic force rating between N42 and N55, preferably N52; the magnetic head is cylindrical (or prismatic, disc-shaped, or square-shaped, etc.), with a length of 4-6 mm, preferably 5 mm, of which 1-2 mm is embedded in the connector assembly body, preferably 1.5 mm, and the exposed portion is 2-5 mm, preferably 3.5 mm, with a diameter of 2-5 mm, preferably 3 mm; its exposed end face is the attraction surface. The connector assembly body has a square or flat cross-section in at least a portion of its length direction, matching the guide cavity. Figure 6-4 The corresponding dimensions were selected.

[0070] The interface method in this application is not limited to magnetic attraction; it can also include structures such as clips, positioning beads, pins, and threads. Magnetic attraction is preferred. The magnetic attraction structure is the only one that uses end-face positioning. Its advantages include a large end-face contact area, a tight face-to-face contact between the magnetic base and the magnetic head, reducing the likelihood of shaking or wobbling, and the absence of frictional force during insertion and removal, thus reducing wear and increasing the number of insertions and removals. The side of the plug only serves as a guide and further assists in reducing shaking and wobbling. Other structures use side-positioning on the plug, such as positioning pins and clips, which are secured to the side of the connector rather than the end face. If too loose, they cannot limit the shaking or wobbling of the plug; if too tight, they are difficult to remove. Moreover, relying on friction for positioning leads to wear after many insertions and removals. Even if there is no shaking or wobbling initially, it will gradually develop over time. This can easily cause a "crooked leg" phenomenon when removing glasses with one hand due to shaking or wobbling at the interface and connector. This embodiment solves this problem.

[0071] like Figure 6-5 The image shown is a schematic diagram of the glasses when using a magnetic connector in this embodiment. Figure 6-6 This refers to the case where the interface component is installed in the charging case. There are two types of interface components: one with electronic components (made into an earphone shape) and one without electronic components. Figure 6-7 This is another case where the interface component is installed in the charging case, where there is only one type of interface component, which is equipped with electronic components (earphone form).

[0072] The ear support of the head-mounted smart device in this application can be considered a type of headphone in an acoustic sense. However, since it may integrate smart devices, it may be a multi-functional headphone or a smart headphone, or it may be other smart devices with a sound-generating device. Since the ear is part of the head, it is called a head-mounted smart device.

[0073] Because it has a first opening and a positioning cavity, and the first opening communicates with the positioning cavity, and the positioning cavity contains a positioning component, the positioning component is used to cooperate with a connector component provided on the external bracket to connect the ear bracket to the external bracket in a way that allows for repeated disassembly and detachment by hand. In this way, when the external bracket is an eyeglass temple, it can be used as a universal component for connecting eyeglass temples, and can be plugged into various different eyeglasses. Therefore, it has strong versatility, forming a completely new category, which can be called "Universal Eyeglass Adapter," meaning "universal for all kinds of eyeglasses"; or "Ear-Connecting Eyeglass Adapter," or "Ear-Connecting Eyeglass Adapter." Although the external bracket as an eyeglass temple extends from the eyeglass frame, it is only half-length and has a connector device that is not as good as ordinary eyeglass temples. Therefore, it is still a completely new category, which can be called "Universal Ear Adapter," meaning "universal for all kinds of headphones"; or "Ear-Connecting Eyeglass," meaning "eyeglasses that connect to headphones."
