Description

Technical Field

[0001] This utility model relates to the field of smart glasses, and in particular to a glasses temple with an audio structure. Background Technology

[0002] Currently, most smart glasses on the market integrate audio functions. This is usually achieved by embedding a miniature speaker (audio module) inside the temple of the glasses, near the upper part of the ear, with the speaker opening facing the lower ear canal, in order to achieve short-range directional transmission of sound.

[0003] However, due to the extremely limited internal space of the glasses' temples, the volume of the acoustic cavity that the audio module can accommodate is too small, making it difficult to create an ideal acoustic resonance environment. This results in thin sound quality and poor performance, failing to meet users' expectations for a high-quality audio experience. Utility Model Content

[0004] The purpose of this invention is to provide an eyeglasses temple with an audio structure, in which a speaker is installed inside the ear hook, and the sound channel opened inside the ear hook is used to increase the volume of the sound cavity, thereby improving the sound quality.

[0005] The technical solution adopted by the eyeglass temple with an audio structure disclosed in this utility model is as follows:

[0006] The glasses include temples, on which an integrally formed ear loop is formed. A sound cavity is formed inside the ear loop, and a speaker is provided inside the sound cavity. A sound outlet is formed on the temple, and a sound channel is formed inside the ear loop. The two ends of the sound channel are respectively connected to the sound cavity and the sound outlet.

[0007] As a preferred embodiment, the cross-section of the vocal tract along its axial direction first gradually narrows and then gradually expands.

[0008] As a preferred embodiment, the temple is composed of a first housing and a second housing combined together, the lug is composed of the end of the first housing and the end of the second housing extending and combined together, the sound cavity, the sound channel and the sound outlet are all located on the first housing, and the second housing covers the sound cavity and the sound channel.

[0009] As a preferred embodiment, the system also includes a partition plate with multiple limiting posts extending from it. Multiple limiting holes are provided inside the sound channel. The limiting posts are fixed by engaging adjacent limiting holes. The partition plate seals the sound channel, and the second housing contacts the partition plate.

[0010] As a preferred embodiment, the acoustic cavity is provided with a connection hole communicating with one end of the sound channel, and multiple protrusions extend from the inner wall of the acoustic cavity. The speaker touches the protrusions, and the second housing touches the speaker.

[0011] The beneficial effects of the eyeglass temple with an audio structure disclosed in this utility model are:

[0012] When a user wears eyeglasses with temples, the sound outlet faces the ear canal. The sound waves emitted by the speaker located in the sound cavity propagate to the ear canal through the sound channel and the sound outlet. Because the slender structure of the sound channel provides a good acoustic resonance environment for the propagation of sound waves, the sound quality is improved.

[0013] In addition, the speakers are placed inside the ear loops, which are covered behind the user's ears, thus concealing the increased size of the ear loops due to the embedded speakers; the temples can therefore be designed to be slimmer, significantly improving the overall aesthetics of the eyeglasses frame.

[0019] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0020] Please refer to Figures 1-4 .

[0021] This utility model discloses an eyeglass temple with an audio structure, including a temple 1 and a partition 2;

[0022] The temple 1 has an integrally formed hanging ear 13 extending from its end. In this embodiment, the temple 1 is preferably composed of a first housing 11 and a second housing 12 combined together, with the hanging ear 13 formed by the extension and merging of the ends of the first housing 11 and the second housing 12.

[0023] A sound cavity 111 is formed inside the ear loop 13, and the sound cavity 111 is located at the end of the ear loop 13. A speaker 14 is installed in the sound cavity 111. Given that the end of the ear loop 13 of existing eyeglass frames usually has a large space, compared with the existing solution of pre-embedding the audio module in the middle of the temple, the increase in size of the speaker 14 added to the end of the ear loop 13 in this solution is not obtrusive. In addition, the ear loop 13 is hidden behind the user's ear, so the increase in size of the ear loop 13 after the speaker 14 is embedded can be naturally hidden. The temple 1 can therefore be designed to be more slender, thereby significantly improving the overall aesthetics of the eyeglass frame.

[0024] Furthermore, the sound cavity 111 is located inside the first housing 11, and multiple protrusions extend from the inner wall of the sound cavity 111. The multiple protrusions are arranged at intervals on the inner wall of the sound cavity 111, and the sound output surface of the speaker 14 touches the protrusions, so that there is a certain space between the sound output surface of the speaker 14 and the bottom of the sound cavity 111; the second housing 12 touches the back of the speaker 14, and the second housing 12 constrains the speaker 14 inside the sound cavity 111;

[0025] Furthermore, a connecting hole 112 is provided on the inner wall of the sound cavity 111. The connecting hole 112 is located between the sound-emitting surface of the speaker 14 and the bottom of the sound cavity 111. The aforementioned space formed by the raised speaker 14 allows the sound waves emitted by the speaker 14 to enter the connecting hole 112 through this space.

[0026] The temple 1 has a sound outlet 113, which is located in the middle of the first housing 11 and below the first housing 11, so that when the user wears the eyeglasses frame with the temple 1, the sound outlet 113 is located above the ear canal and faces the ear canal.

[0027] Furthermore, a sound channel 114 is provided inside the ear hook 13. One end of the sound channel 114 is connected to the sound cavity 111 through the connecting hole 112, and the other end of the sound channel 114 extends into the temple 1 and is connected to the sound outlet 113; so that the sound waves emitted by the speaker 14 located in the sound cavity 111 are transmitted to the ear canal through the connecting hole 112, the sound channel 114 and the sound outlet 113.

[0028] Furthermore, the sound channel 114 is located inside the first housing 11. In this embodiment, the cross-section of the sound channel 114 along its axial direction is preferably in the shape of gradually narrowing and then gradually expanding, and the cross-sectional area at both ends of the sound channel 114 is larger than the cross-sectional area in the middle of the sound channel 114.

[0029] The tapered-and-expanded cross-section design of channel 114 achieves the following acoustic effects:

[0030] Sound wave convergence and density enhancement: When the sound wave propagates axially from one end of the channel 114, the cross-section gradually narrows, converging and compressing the sound wave towards the center of the channel 114, thus increasing the sound wave density at the sound outlet 113. This effectively compensates for the defect that the sound energy cannot be fully focused due to the short propagation distance of the channel 114.

[0031] Low-frequency band (100-300Hz) enhancement: This structure can increase the sound pressure level (SPL) by 3-5dB by compressing the sound waves. This feature is particularly beneficial for compensating for the low-frequency performance of the miniature speaker 14, which has a small diaphragm area and weak low-frequency radiation capability, and enhances the bass extension of the sound quality. At the same time, this structure can further reduce the low-frequency resonance frequency of the channel 114 from (250Hz) to (200Hz) and below, and reduce the (3dB) low-frequency cutoff frequency by about 15%, significantly enhancing the bass extension.

[0032] Mid-to-low frequency band (200-500Hz) enhancement: The wavelength of sound waves in this frequency band is relatively long (e.g., 500Hz≈680mm), making it difficult to form standing waves within channel 114. However, through the compression effect of the sound waves by the channel 114 structure, the fundamental frequency band of human voice (200-400Hz) can be precisely enhanced, effectively improving speech clarity, such as in headphone call scenarios.

[0033] Suppressing high-power turbulence noise (especially 1-5kHz): When the speaker 14 outputs high power, the airflow velocity within the channel 114 increases. Under the same flow rate, the shorter the channel 114, the greater the velocity gradient, and the higher the risk of turbulence noise, especially mid-to-high frequency noise (1-5kHz) that is easily perceived by the human ear. This channel 114 structure can guide the airflow to accelerate smoothly along the axis, avoiding airflow separation and vortex formation caused by sudden contraction, thereby reducing turbulence noise (5-8dB). In addition, when transmitting high-frequency speech details (such as 3kHz), this channel 114 design can significantly reduce the masking of high-frequency details by airflow noise, improving sound clarity.

[0034] Please refer to Figure 3 and Figure 5 .

[0035] Multiple limiting posts 211 extend from the partition 2, and multiple limiting holes 115 are opened in the sound channel 114. The limiting holes 115 do not affect the transmission of sound waves in the sound channel 114. The limiting posts 211 are fixed by being inserted into adjacent limiting holes 115. The partition 2 is installed in the sound channel 114 so that the partition 2 seals the sound channel 114. The second housing 12 touches the partition 2 and constrains the partition 2 onto the first housing 11.

[0036] The sound leakage problem of the sound channel 114 is solved by covering the sound channel 114 with the partition 2.

[0037] This utility model provides an eyeglass temple with an audio structure. When the user wears an eyeglass frame with temples, the sound outlet faces the ear canal. The sound waves emitted by the speaker located in the sound cavity are transmitted to the ear canal through the sound channel and the sound outlet. Because the slender structure of the sound channel provides a good acoustic resonance environment for the propagation of sound waves, the sound quality is improved.

[0038] In addition, the speakers are placed inside the ear loops, which are covered behind the user's ears, thus concealing the increased size of the ear loops due to the embedded speakers; the temples can therefore be designed to be slimmer, significantly improving the overall aesthetics of the eyeglasses frame.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
