Description

Technical Field

[0001] This application relates to the technical field of AR glasses, and in particular to a directional open AR glasses. Background Technology

[0002] Currently, AR glasses, as a crucial carrier of AR technology, provide users with an immersive visual experience, demonstrating immense potential in various fields such as entertainment, education, and industry. They combine virtual information with real-world scenes, allowing users to perceive and interact with the world around them in entirely new ways, greatly expanding people's horizons and cognitive range. AR glasses incorporate speaker structures that emit sound wave signals to provide users with a better experience through the combination of sound wave signals and image signals. As an important component of wearable devices, the acoustic conduction technology of AR glasses directly impacts the user experience.

[0003] In traditional AR glasses, two common sound transmission methods are used to achieve audio functionality: bone conduction and in-ear technology. Bone conduction technology uses a vibrating unit placed in the temples or frame to conduct sound through the skull to the inner ear. In-ear technology uses earphones extending from the temples, inserted into the ear canal to transmit sound. Bone conduction technology has the advantage of not blocking the ear canal, making it suitable for extended wear, but its sound quality is greatly affected by the tightness of the fit and its low-frequency response is relatively poor. While in-ear technology offers better sound quality, prolonged wear may cause ear canal pressure.

[0004] In view of the aforementioned technologies, it is necessary to propose a directional open-type AR glasses to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the aforementioned technical issues, this application provides a directional open-type AR glasses.

[0006] This application provides a directional open-type AR glasses solution, which adopts the following technical solution:

[0007] A directional open-back AR glasses system includes a frame and two temples symmetrically arranged on both sides of the frame. The upper end of the temple's tail section has a groove. The system also includes:

[0008] The housing is combined with one side of the tail end of the temple, and the housing is provided with a plurality of sound outlet holes facing the auricle and toward the ear canal;

[0009] An audio module, disposed within the housing, is capable of emitting sound wave signals and transmitting these signals to the sound outlet, allowing the sound waves to propagate from the sound outlet toward the ear canal; and

[0010] An adjustment component is used to adjustably connect the housing to the end of the temple of the glasses to adjust and position the sound outlet direction relative to the ear hole.

[0011] By adopting the above technical solution, the audio module is set inside the housing, which can emit sound wave signals and transmit them to the sound outlet. Since the housing is combined with one side of the temple, and the sound outlet of several sound outlets on the housing is oriented towards the auricle and ear canal, the sound wave signals can be accurately transmitted from the sound outlet to the ear canal. This can effectively direct the sound to the user's ear, realize directional audio playback, reduce sound leakage, avoid interference with the surrounding environment, and allow the user to receive audio information more clearly, thus improving the audio listening experience. Furthermore, by adjusting the position of the housing on the auricle using the adjustment component, the sound outlet direction of the housing can be conveniently and directionally transmitted to the user's ear and maintained in a stable manner.

[0012] Optionally, the adjustment assembly includes a stabilizing plate disposed within the groove, an adjustment rod disposed above the side of the stabilizing plate, and a combination piece connected to the side of the housing. The end of the adjustment rod is rotatably provided with a knob sleeve, and the combination piece is connected to the knob sleeve.

[0013] By adopting the above technical solution, a groove is opened at the upper end of the temple, and the stabilizing plate is placed in the groove, which makes the installation of the adjustment component on the temple more stable. An adjustment rod is set above the side of the stabilizing plate, and a knob sleeve is set at the end of the adjustment rod. The assembly piece is connected to the knob sleeve and connected to the side of the housing. In this way, the angle of the assembly piece can be flexibly adjusted by rotating the knob sleeve, thereby adjusting the angle of the housing connected to the assembly piece. This allows for flexible control of the direction of the sound hole, so as to better and more accurately transmit the sound wave signal to the ear hole and improve the user's audio listening effect.

[0014] Optionally, the stabilizing plate includes a base plate inserted into the groove and an adjusting plate adjusted on the base plate. The top of the base plate is provided with an adjusting groove, and the adjusting plate is raised and lowered within the adjusting groove. The adjusting plate and the base plate are provided with a plurality of locking holes through the adjusting groove, and locking bolts are provided in the overlapping locking holes. The inner wall of the groove and the side of the base plate are provided with first magnetic absorbing pieces, which are magnetically attracted to each other. The tail end of the adjusting rod is connected to the adjusting plate.

[0015] By adopting the above technical solution, the stabilizing plate consists of a base plate inserted into a groove and an adjusting plate set on the base plate. The adjusting groove on the top of the base plate allows the adjusting plate to be raised and lowered. Several locking holes are provided through the adjusting groove between the adjusting plate and the base plate. When the adjusting plate is raised or lowered to the appropriate position, the locking bolt is inserted into the overlapping locking holes to lock the position of the adjusting plate, thereby realizing the adjustment of the height of the stabilizing plate to adapt to different usage needs. At the same time, the inner wall of the groove and the side of the base plate are provided with first magnetic absorbing pieces. The first magnetic absorbing pieces are magnetically attracted to each other. This not only enhances the connection stability between the stabilizing plate and the end of the temple, preventing the stabilizing plate from easily shaking or falling off, but also plays a role in positioning and assisting installation, so that the stabilizing plate is accurately inserted into the groove. In addition, the end of the adjusting rod is connected to the adjusting plate. When the height of the stabilizing plate is adjusted, it can drive the adjusting rod and other connected components to make corresponding position adjustments, thereby realizing flexible adjustment of the position and angle of the entire adjusting assembly.

[0016] Optionally, the outer surface of the control rod and the inner wall of the knob sleeve are both provided with second magnetic pieces. The combined piece is adjusted at the end of the control rod by the knob sleeve, and the knob sleeve is positioned at the end of the control rod by magnetic attraction between the second magnetic pieces.

[0017] By adopting the above technical solution, the second magnetic absorbing piece set on the outer surface of the control rod and the inner wall of the knob sleeve can realize the angle adjustment of the combined piece by the knob sleeve at the end of the control rod through the magnetic attraction principle. After the appropriate angle is adjusted, the knob sleeve can be firmly positioned at the end of the control rod through the magnetic attraction between the second magnetic absorbing pieces, which makes it convenient to flexibly adjust the angle of the combined piece to meet different usage needs, while ensuring the stability of the positioning.

[0018] Optionally, the audio module includes a printed circuit board disposed within the housing, a speaker for audio playback, and a battery for power supply, wherein the printed circuit board is electrically connected to the speaker and the battery, respectively.

[0019] By adopting the above technical solution, the battery provides power to the entire audio module, and the printed circuit board, as the circuit carrier, can distribute and regulate the power provided by the battery, ensuring that the speaker receives a stable and appropriate power supply, thereby enabling the speaker to play audio stably and normally, and realizing the audio playback function of the audio module.

[0020] Optionally, a sound guiding channel is provided inside the housing, and the speaker is provided corresponding to the sound guiding channel, with the sound output direction of the speaker being in the same direction as the sound guiding channel's outlet.

[0021] By adopting the above technical solution, the sound wave signal emitted by the speaker can propagate directly and efficiently along the sound guide channel, reducing the scattering and loss of sound waves during propagation. This allows more sound wave signals to propagate accurately from the guide port of the sound guide channel toward the ear canal, effectively improving the directionality and volume of sound propagation, and enabling users to receive the sound emitted by the audio module more clearly.

[0022] Optionally, the housing has a positioning frame inside that fits the size of the printed circuit board, the printed circuit board is snapped into the positioning frame, and adhesive stickers are provided on all four sides of the inner wall of the positioning frame, the adhesive stickers being connected to the side of the printed circuit board.

[0023] By adopting the above technical solution, the positioning frame can be used to initially limit and fix the printed circuit board, so that the printed circuit board can be accurately positioned in a specific location within the housing. The printed circuit board is snapped into the positioning frame, which enhances the connection stability between the printed circuit board and the positioning frame and reduces the shaking of the printed circuit board within the housing. At the same time, adhesive stickers are set around the inner wall of the positioning frame and connected to the sides of the printed circuit board, further improving the connection between the printed circuit board and the positioning frame. This effectively prevents the printed circuit board from shifting or loosening due to vibration, collision, or other factors during use, ensuring that the printed circuit board maintains a stable installation state within the housing, thereby guaranteeing the normal operation of the audio module.

[0024] Optionally, the temple end is provided with a detachable support section, the support section has a disassembly groove, the temple end is provided with a disassembly block, and the support section is connected to the temple end by inserting the disassembly block into the disassembly groove.

[0025] By adopting the above technical solution, this detachable connection method makes the installation and disassembly of the support section more convenient. When the support section is damaged or needs to be replaced with a support section of a different style or size, it is not necessary to replace the entire temple. Simply remove the damaged or original support section from the end of the temple and then install the new support section by inserting it into the disassembly slot through the disassembly block. This reduces maintenance costs and also meets the user's requirement to flexibly replace the support section according to different usage scenarios and personal needs.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The sound outlet faces the auricle and is directed toward the ear canal. The sound wave signal emitted by the audio module propagates from the sound outlet toward the ear canal, providing a directional audio experience and reducing the diffusion of sound into the surrounding environment.

[0028] 2. The adjustment assembly allows for combined adjustment of the housing and the end of the temple. The combination connection is flexible, and the control rod and knob sleeve can be used to adjust the angle and position the lens. This makes it easy for users to adjust the sound direction according to their own needs. It also facilitates the installation and disassembly of the housing, making it convenient for maintenance and replacement. Attached Figure Description
