[0032] Hereinafter, the technical solutions in the embodiments of the present invention will be described clearly and in detail in conjunction with the accompanying drawings in the embodiments of the present invention, but it should be understood that the described embodiments are only some of the embodiments of the present invention and are not limited thereto. Furthermore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are included in the protection scope of the present invention.

[0033] (First embodiment) The present invention provides smart wearable glasses 100.

[0034] Please refer to Figures 1 to 9.

[0035] The smart wearable glasses 100 include a frame 1, temples 2, a vibration unit 3, and a sound generating unit 4.

[0036] The frame 1 can be used to fix a lens, but it can also be worn without a lens.

[0037] The temples 2 extend from both opposing sides of the frame 1. The temples 2 are made up of two temples, and the two temples 2 are symmetrically installed as mirror images.

[0038] The temple 2 has a hollow structure. The temple 2 is used to attach the vibration unit 3 and the sound generating unit 4.

[0039] Specifically, the temple 2 includes a first temple body 21 extending from the frame 1, a first temple cover 22 that is covered and fixed to the first temple body 21 and surrounds the first temple body 21 to form a first sound chamber 20, and a second sound emission hole 201, a second antiphase hole 202, and a second leakage hole 203 that each penetrate the first temple body 21.

[0040] The temple 2 includes a lower surface S1 for being placed over the ear of a user when worn, an upper surface S2 opposite the lower surface S1, and a first side surface S3 and a second side surface S4 connected to the upper surface S2 and the lower surface S1 and disposed opposite each other. The second sound emission hole 201 and the second antiphase hole 202 are disposed at an interval on the lower surface S1. This arrangement can reduce sound leakage.

[0041] The second leakage hole 203 is provided on the upper surface S2. The second leakage hole 203 and the second sound output hole 201 are provided on the upper surface S2 and the lower surface S1, respectively, and significantly reduce low-frequency sound leakage from the sound generating unit 4 based on the principle of sound wave antiphase cancellation.

[0042] The first side surface S3 is provided on a side closer to a user. The first temple cover 22 is provided on the first side surface S3.

[0043] The vibration unit 3 is attached and fixed to the temple 2. In this embodiment I, the vibration unit 3 is attached and fixed to the end of the temple 2 remote from the frame 1.

[0044] Specifically, the vibration section 3 includes a bone conduction contact section 31, a vibrator 32, a vibration conductive layer 33, and a vibration coupling anvil .

[0045] At least a portion of the bone conduction contact portion 31 is exposed to the temple 2, and the bone conduction contact portion 31 is used for direct contact with the skin of the user. The bone conduction contact portion 31 is used for contacting the bone of the head of the user and transmitting the vibration sound signal generated by the vibration portion 3 to the user by bone conduction.

[0046] When the smart wearable glasses 100 are worn, the bone conduction contact portion 31 comes into direct contact with the skin near the human ear. The bone conduction contact portion 31 is made of a soft material, and in this embodiment I, the bone conduction contact portion 31 is a soft sound-conducting medium, specifically, may be a rubber layer or a foam layer. With this configuration, the wearing comfort of the smart wearable glasses 100 can be improved, and the vibration isolation between the vibration portion 3 and the temple 2 can be enhanced, resulting in better sound effects and better listening comfort.

[0047] The vibrator 32 generates the vibration audio signal.

[0048] In the first embodiment, the vibrator 32 is any one of a motor, an actuator, and a bone conduction transducer. More preferably, the vibrator 32 is an inertial vibration actuator, which is particularly excited to generate the vibration sound signal at low frequency.

[0049] The vibration conductive layer 33 is attached to the surface of the vibrator 32. The vibration conductive layer 33 and the vibration coupling anvil 34 may be separate bodies or may be integrated together.

[0050] The vibration coupling anvil 34 is attached to the vibration conductive layer 33. The bone conduction contact portion 31 is attached to the side of the vibration coupling anvil 34 away from the vibration conductive layer 33. The vibration coupling anvil 34 is coupled to a bone of a user's head via the bone conduction contact portion 31 to form a bone conduction arrangement.

[0051] The shape and size of the vibration coupling anvil 34 corresponds to the shape and size of the bone to which it is coupled, i.e., the vibration coupling anvil 34 is coupled to the shape and size of the bone at the corresponding position of the human head, and may be a non-metallic part having a certain rigidity, such as plastic.

[0052] The sound generating unit 4 is attached and fixed to the temple 2 .

[0053] Specifically, the sound generating section 4 is composed of a housing 41 , a sound generating unit 42 , and an anti-phase tube 43 .

[0054] The housing 41 has an accommodating space 401 and an antiphase passage 402. The housing 41 is provided with a first sound output hole 403, a first antiphase hole 404, and a first leakage hole 405, each penetrating the housing 41. Here, the first sound output hole 403 communicates with the outside through the second sound output hole 201. The first antiphase hole 404 communicates with the outside through the second antiphase hole 202. The first leakage hole 405 communicates with the outside through the second leakage hole 203.

[0055] The housing 41 includes a bottom wall 411 fixedly accommodated within the first sound chamber 20, a side wall 412 extending and curving from the periphery of the bottom wall 411 toward the first sound chamber 20, a top cover 413 covered and fixed to the side wall 412, a support wall 414 extending from the bottom wall 411 toward the top cover 413, and an inverted phase tube cover 415.

[0056] The bottom wall 411 , the side wall 412 , the support wall 414 and the anti-phase tube cover 415 together enclose and define the anti-phase passage 402 .

[0057] The bottom wall 411 , the side wall 412 , the support wall 414 and the top cover 413 together surround the receiving space 401 .

[0058] The first sound emission hole 403 , the first antiphase hole 404 and the first leakage hole 405 each penetrate the side wall 412 .

[0059] The sound generating unit 42 is fixed within the accommodation space 401. Specifically, the sound generating section 4 is accommodated and fixed in the first sound chamber 20.

[0060] The sound generating unit 42 divides the accommodation space 401 into a front chamber 406 and a combined rear chamber 407. The front chamber 406 communicates with the outside through the first sound output hole 403. The sound signal emitted by the sound generating unit 42 passes through the front chamber 406 and the first sound output hole 403, and propagates in the vicinity of the free sound field to transmit a mid- to high-frequency sound signal to the human ear.

[0061] More preferably, the first sound emitting hole 403 is disposed at the position of the pinna of the human ear and is installed toward the human ear, i.e., the second sound emitting hole 201 is installed at a position corresponding to the first sound emitting hole 403 of the temple 2 to cooperate with the first sound emitting hole 403. The second sound emitting hole 201 is located on the lower surface S1 of the temple 2, i.e., the second sound emitting hole 201 is also disposed at the position of the pinna of the human ear and is installed toward the human ear. More preferably, the cross-sectional shape of the first sound emitting hole 403 is similar to the shape of the human ear at the position of the first sound emitting hole 403, so that the human ear can receive the audio signal from the sound generating unit 4 more effectively.

[0062] The post-coupling chamber 407 communicates with the outside via the first leakage hole 405 and the anti-phase tube 43, respectively.

[0063] The sound waves emitted by the sound generating unit 4 through the first sound output hole 403 are in opposite phase to the sound waves emitted by the sound generating unit 4 through the first leakage hole 405. This configuration utilizes the sound configuration of the first sound output hole 403 and the first leakage hole 405, and significantly reduces low-frequency sound leakage from the sound generating unit 4 through the principle of sound wave opposite phase cancellation, thereby effectively preventing sound leakage and improving privacy. Therefore, the smart wearable glasses 100 provided by the present invention have good sound performance.

[0064] In the first embodiment, the first leakage hole 405 is made up of a plurality of holes. The second leakage hole 203 is made up of a plurality of holes. The first leakage holes 405 correspond to the second leakage holes 203, respectively. With this configuration, the plurality of first leakage holes 405 cooperate to easily adjust the sound leakage of the smart wearable glasses 100 provided by the present invention at various angles, and the sound performance of the smart wearable glasses 100 provided by the present invention can be improved.

[0065] The antiphase tube 43 is installed in the antiphase passage 402. The antiphase tube 43 passes through the antiphase passage 402 and the first antiphase hole 404 in sequence to communicate with the outside. With this configuration, the low-frequency performance of the sound generating unit 4 can be significantly improved by utilizing the sound configuration of the antiphase tube 43. The sound generating unit 4 strengthens the sound and strengthens the subwoofer through the antiphase passage 402 and the first antiphase hole 404. After the antiphase tube 43 is installed, a relatively strong sound wave is emitted from the first antiphase hole 404, and by utilizing the sound waves from the first sound emission hole 403 and the first antiphase hole 404 of the sound generating unit 4, the sound quality of the sound generating unit 4 is improved, and the acoustic performance of the smart wearable glasses 100 provided by the present invention is good.

[0066] In the first embodiment, the dimensions of the antiphase tube 43 are calculated by combining the volume of the front chamber 406, the volume of the rear coupling chamber 407, and the TS parameters of the sound generating unit 42. The dimensions of the antiphase tube 43 vary depending on the components of the sound generating section 4. With this configuration, the low frequency characteristics of the sound generating section 4 can be significantly improved.

[0067] In this first embodiment, the vibration unit 3 and the sound generating unit 4 are respectively generated by a frequency division design. The frequency division design includes physical frequency division and software frequency division. According to the frequency division, the sound generating unit 4 operates in a low-medium frequency band, and the vibration unit 3 operates in a medium-high frequency band, so that the sound performance of the smart wearable glasses 100 provided by the present invention is good. The vibration unit 3 and the sound generating unit 4 form a complementary frequency band, so that the smart wearable glasses 100 realizes wide frequency sound reproduction in the low frequency band and the medium-high frequency band, and has a wide frequency band and good sound performance. At the same time, the vibration unit 3 complements the sound generating unit 4 in the low frequency sound band, so that the sound generating unit 4 can enhance the low frequency effect without increasing the size, thereby avoiding the leakage of medium and high frequency sounds, effectively improving the privacy problem of the smart wearable glasses 100, and further improving the user's experience effect.

[0068] Below, the prototype smart wearable glasses 100 according to the first embodiment are measured, and a comparative explanation is given based on the measured curves.

[0069] Referring to FIG. 10, FIG. 10 is a diagram showing a comparison of sound pressure level frequency relationship curves of the smart wearable glasses 100 according to the first embodiment of the present invention and smart wearable glasses according to the related art.

[0070] 10, W1 is the sound pressure level-frequency relationship curve of the smart wearable glasses 100, and W2 is the sound pressure level-frequency relationship curve of the smart wearable glasses of the related art. The smart wearable glasses 100 according to the first embodiment of the present invention differ from the smart wearable glasses of the related art in the following points.

[0071] Compared with the smart wearable glasses of the related art, the smart wearable glasses 100 of the first embodiment of the present invention add configurations corresponding to the first leakage hole 405 and the first anti-phase hole 404, as can be seen from FIG. 10, so that the smart wearable glasses 100 of the present invention can greatly improve the low-frequency response, increase the frequency band below 450 Hz, and the low-frequency improvement at 100 Hz can be up to 16 dB.

[0072] Referring to Figure 11, Figure 11 is a diagram showing a comparison of frequency relationship curves of the sound pressure level at the outer position of the user's ear when using smart wearable glasses 100 according to the first embodiment of the present invention, and the sound pressure level at the inner position of the ear when using smart wearable glasses according to the related technology.

[0073] In FIG. 11, W3 is the sound pressure level frequency curve of the smart wearable glasses of the related art at the inner position of the ear, and W4 is the sound pressure level frequency curve of the smart wearable glasses 100 at the outer position of the ear 20 cm. Compared with the smart wearable glasses of the related art, the smart wearable glasses 100 according to the first embodiment of the present invention adds a configuration corresponding to the first leakage hole 405 and the first anti-phase hole 404, respectively, and as can be seen from FIG. 11, the difference in the sound response heard by the user of W3 and W4 is large, and is greater than 25 dB between 100 Hz and 4 kHz, and the maximum difference value is greater than 40 dB, and the effect of preventing sound leakage is good. In addition, the frequency band above 4 kHz is mainly transmitted to the human ear by the vibration parts through bone conduction, so privacy can be extremely protected.

[0074] To sum up, the smart wearable glasses 100 provided by the present invention utilizes the audio configuration of the anti-phase tube 43 to greatly improve the low-frequency performance of the sound generating unit 4, and by using the principle of sound wave anti-phase cancellation, can greatly reduce the low-frequency sound leakage from the sound generating unit 4. The vibration unit 3 transmits sound directly to the ear through bone conduction by contact vibration, avoiding the sound leakage phenomenon, ensuring privacy at mid- and high-frequency frequencies, and reducing sound leakage in the entire frequency band to improve privacy, which improves the user experience and the audio performance of the smart wearable glasses 100 provided by the present invention is good.

[0075] Second embodiment The second embodiment of the present invention provides smart wearable glasses 100a. Referring to Fig. 12 and Fig. 13, Fig. 12 is a schematic diagram of a three-dimensional configuration of the smart wearable glasses 100a according to the second embodiment of the present invention, and Fig. 13 is a schematic diagram of a partial three-dimensional configuration disassembled of the temples and sound generating unit 4a of the smart wearable glasses 100a according to the second embodiment of the present invention.

[0076] The smart wearable glasses 100a of the second embodiment have the same basic configuration as the smart wearable glasses 100 of the first embodiment of the present invention, but the differences between them are as follows.

[0077] The temple 2a includes a second temple body 21a extending from the frame 1a, and a second temple cover 22a that is covered and fixed to the second temple body 21a and surrounds the second temple body 21a to form a second sound chamber 20a.

[0078] The housing 41a is formed by extending the second temple body 21a toward the second sound chamber 20a.

[0079] The sound generating unit 4a is housed and fixed in the second sound chamber 20a.

[0080] The first sound emission hole 403a, the first antiphase hole 404a, and the first leakage hole 405a each penetrate the second temple body 21a.

[0081] In the smart wearable glasses 100a according to the second embodiment, the housing 41a of the sound generating unit 4a is designed integrally with the temple 2a. This configuration simplifies the manufacturing process to reduce costs and reduces the weight and volume of the smart wearable glasses 100a, so that the smart wearable glasses 100a according to the second embodiment can be made small and lightweight, improving the user experience.

[0082] As described above, according to the configuration of the smart wearable glasses 100 according to the first embodiment and the smart wearable glasses 100a according to the second embodiment, the low frequency performance of the sound generating unit can be greatly improved, and the principle of sound wave antiphase cancellation can greatly reduce the sound leakage at low frequencies of the sound generating unit; furthermore, the vibration unit transmits sound to the ears through direct contact vibration by bone conduction, avoiding the sound leakage phenomenon, and ensuring privacy in the mid- and high-frequency bands, thereby realizing reduced sound leakage and improved privacy in the entire frequency band, and providing a good user experience. Therefore, the sound performance of the smart wearable glasses provided by the present invention is good.

[0083] Compared with the related art, the smart wearable glasses provided by the present invention are configured to provide a sound generating unit and a vibration unit in the temple. The housing of the sound generating unit includes an antiphase passage and a first antiphase hole, and an antiphase tube is installed in the antiphase passage, and the antiphase tube passes through the antiphase passage and the first antiphase hole sequentially to communicate with the outside. In this way, the sound configuration using the antiphase tube can significantly improve the low-frequency performance of the sound generating unit. The housing includes an accommodation space, a first sound output hole, and a first leakage hole, and the accommodation space is divided into a front chamber and a rear combination chamber by the sound generating unit, the front chamber communicates with the outside through the first sound output hole, and the rear combination chamber communicates with the outside through the first leakage hole and the antiphase tube, respectively. The phase of the sound wave emitted by the sound generating unit through the first sound output hole is inverse to the phase of the sound wave emitted by the sound generating unit through the first leakage hole. This configuration utilizes the audio configuration of the first sound emission hole and the first leakage hole, and by the principle of sound wave antiphase cancellation, the low frequency sound leakage in the sound generating unit is greatly reduced. In addition, the vibration unit transmits sound to the ear by direct contact vibration through bone conduction, avoiding the sound leakage phenomenon and ensuring privacy of mid- and high-frequency sounds, and improving the user experience by realizing reduced sound leakage and improved privacy in the entire frequency band. As a result, the smart wearable glasses provided by the present invention have good audio performance.

[0084] It should be noted that the above is merely an embodiment of the present invention, and various improvements can be made by those skilled in the art without departing from the gist of the present invention, and these are included in the scope of protection of the present invention.
