Description

Technical Field

[0001] The present invention relates to the field of electro-acoustic conversion, and particularly to smart wearable glasses (smart glasses) used in portable mobile electronic products.

Background Art

[0002] Smart wearable glasses are widely used in various fields such as communication, education, medical care, culture, and manufacturing. Therefore, the audio performance of smart wearable glasses is a major factor affecting the user experience.

[0003] Related smart wearable glasses include a frame, temple parts with a hollow structure extending from both sides of the frame facing each other, and a vibration component and a sound generation component respectively installed and fixed in the temple parts. The sound generation component transmits low and medium frequency sounds to the human ear through the sound generation holes in the temple parts to ensure the sound quality effect. The inner side of the vibration component can be directly attached to the skull, easily transmitting sound and transmitting high frequency sound waves to the human ear to realize the audio playback of smart wearable glasses.

[0004] However, in the process of the sound emitted by the sound generation component of related smart wearable glasses being conducted to the user's ear through the sound generation holes in the temple parts, high frequencies are attenuated. The open cross-talk is directly radiated into the air, which is disadvantageous for privacy protection and the sound leakage is serious. In particular, in the range of 100 Hz to 450 kHz, the sound pressure level of the low frequency sound becomes low. By the way, the vibration component can suppress sound leakage by using the open auditory cross-talk of bone conduction and improve privacy. However, since the vibration amplitude at low frequencies of bone conduction is too large, it is easy to give discomfort to the user. How to improve the audio transmission in the low frequency band, increase the sound pressure level (SPL) to reduce sound leakage, and improve the audio index of smart wearable glasses is a technical problem to be solved.

[0032] Hereinafter, the technical solutions in the embodiments of the present invention will be clearly and detailedly described in conjunction with the accompanying drawings in the embodiments of the present invention. However, it should be understood that the described embodiments are only a part of the embodiments of the present invention and are not limited thereto. All other embodiments obtained by those skilled in the art without creative work based on the embodiments of the present invention 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 FIGS. 1 to 9.

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

[0036] The frame 1 can be used to fix the lenses. Of course, it is also possible to wear it without lenses.

[0037] The template 2 extends from both opposite sides of the frame 1. The template 2 consists of two parts, and the two templates 2 are symmetrically installed as mirror images.

[0038] The template 2 has a hollow structure. The template 2 is used for attaching the vibrating part 3 and the sound generating part 4.

[0039] Specifically described, the template 2 includes a first template main body 21 extending from the frame 1, a first template cover 22 covered and fixed on the first template main body 21, and together with the first template main body 21, surrounding to form a first sound chamber 20, and a second sound emitting hole 201, a second anti-phase hole 202, and a second leakage hole 203 that respectively penetrate the first template main body 21.

[0040] The template 2 includes a lower surface S1 for being installed on the user's ear during wearing, an upper surface S2 opposite to the lower surface S1, and a first side surface S3 and a second side surface S4 that are connected to the upper surface S2 and the lower surface S1 and are arranged opposite to each other. The second sound emitting hole 201 and the second anti-phase hole 202 are arranged at intervals on the lower surface S1. According to such an arrangement, sound leakage can be reduced.

[0041] The second leakage hole 203 is provided on the upper surface S2. The second leakage hole 203 and the second sound emitting hole 201 are respectively provided on the upper surface S2 and the lower surface S1, and greatly reduce the low-frequency sound leakage in the sound generating part 4 according to the principle of sound wave anti-phase cancellation.

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

[0043] The vibrating part 3 is fixedly attached to the template 2. In Embodiment I, the vibrating part 3 is fixedly attached to the end of the template 2 away from the frame 1.

[0044] Specifically, the vibration unit 3 includes a bone conduction contact portion 31, a vibrator 32, a vibration conduction layer 33, and a vibration coupling anvil 34.

[0045] At least a part of the bone conduction contact portion 31 is exposed to the temple 2, and the bone conduction contact portion 31 is used to directly contact the skin of the user. The bone conduction contact portion 31 contacts the bone of the user's head and is used to transmit the vibration voice signal generated by the vibration unit 3 to the user by bone conduction.

[0046] When the smart wearable glasses 100 are worn, the bone conduction contact portion 31 directly contacts the skin near the human ear. The bone conduction contact portion 31 is made of a soft material. In the first embodiment, the bone conduction contact portion 31 is a flexible voice conduction medium, specifically, it may be a rubber layer or a foam layer. According to such a configuration, the wearing comfort of the smart wearable glasses 100 can be improved, and the vibration prevention between the vibration unit 3 and the temple 2 can be enhanced, and a better voice effect and a better listening experience can be obtained.

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

[0048] In the first embodiment, the vibrator 32 is any one of a motor, an actuator, and a bone conduction transducer. More preferably, an inertial vibration actuator is used for the vibrator 32 to particularly excite the generation of the low-frequency vibration voice signal.

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

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

[0051] The shape and dimensions of the vibration coupling anvil 34 match the shape and dimensions of the bone to which it is coupled. That is, the vibration coupling anvil 34 may be coupled to the shape and dimensions 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 unit 4 is composed of a housing 41, a sound generating unit 42, and an anti-phase tube 43.

[0054] The housing 41 has an accommodation space 401 and an anti-phase passage 402. The housing 41 is provided with a first sound emission hole 403, a first anti-phase hole 404, and a first leakage hole 405 that penetrate it respectively. Here, the first sound emission hole 403 communicates with the outside through the second sound emission hole 201. The first anti-phase hole 404 communicates with the outside through the second anti-phase 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 in the first sound chamber 20, a side wall 412 extending from the periphery of the bottom wall 411 and bending into the first sound chamber 20, a top cover 413 covered and fixed by the side wall 412, a support wall 414 extending from the bottom wall 411 in the direction of the top cover 413, and an anti-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 surround and form the anti-phase passage 402.

[0057] The bottom wall 411, the side wall 412, the support wall 414, and the upper cover 413 together surround to form the accommodation space 401.

[0058] The first sound emission hole 403, the first anti-phase hole 404, and the first leakage hole 405 respectively penetrate the side wall 412.

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

[0060] The sound generation 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 emission hole 403. The sound signal emitted by the sound generation unit 42 passes through the front chamber 406, passes through the first sound emission hole 403, and propagates near the free sound field to transmit the mid-high frequency sound signal to a human ear.

[0061] More preferably, the first sound emission hole 403 is disposed at the position of the auricle of a human ear and is installed in the direction of the human ear. That is, for cooperating with the first sound emission hole 403, the second sound emission hole 201 is installed at a position corresponding to the first sound emission hole 403 of the temple 2. The second sound emission hole 201 is located on the lower surface S1 of the temple 2. That is, the second sound emission hole 201 is also disposed at the position of the auricle of a human ear and is installed in the direction of the human ear. More preferably, the cross-sectional shape of the first sound emission hole 403 is similar to the shape of the human ear at the position of the first sound emission hole 403, so that the human ear can more effectively receive the sound signal from the sound generation part 4.

[0062] The combined rear chamber 407 communicates with the outside through the first leakage hole 405 and the anti-phase tube 43 respectively.

[0063] The sound wave emitted by the sound generating unit 4 through the first sound emission hole 403 is in antiphase with the sound wave emitted by the sound generating unit 4 through the first leakage hole 403. Such a configuration utilizes the sound configurations of the first sound emission hole 403 and the first leakage hole 405, and significantly reduces the low-frequency sound leakage in the sound generating unit 4 based on the principle of sound wave antiphase cancellation, thereby effectively preventing sound leakage and enhancing privacy. Therefore, the smart wearable glasses 100 provided by the present invention have good sound performance.

[0064] In this first embodiment, the first leakage holes 405 are plural. The second leakage holes 203 are plural. The first leakage holes 405 respectively correspond to the second leakage holes 203. According to such a configuration, the plural first leakage holes 405 jointly facilitate adjusting 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 provided in the antiphase passage 402. The antiphase tube 43 sequentially passes through the antiphase passage 402 and the first antiphase hole 404 and communicates with the outside. According to such a configuration, by utilizing the sound configuration of the antiphase tube 43, the low-frequency performance of the sound generating unit 4 can be significantly improved. The sound generating unit 4 enhances the sound through the antiphase passage 402 and the first antiphase hole 404, strengthens the subwoofer. After attaching the antiphase tube 43, a relatively strong sound wave is emitted from the first antiphase hole 404. 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 becomes good.

[0066] In the first embodiment, the dimensions of the inverted-phase tube 43 are calculated by combining the volume of the front chamber 406, the volume of the combined rear chamber 407, and the TS parameters of the sound generation unit 42. The dimensions of the inverted-phase tube 43 vary depending on the components of the sound generation unit 4. According to such a configuration, the low-frequency characteristics of the sound generation unit 4 can be significantly improved.

[0067] In the first embodiment, the vibrating part 3 and the sound generation unit 4 emit sound respectively by frequency division design. The frequency division design includes physical frequency division and software frequency division. According to frequency division, the sound generation unit 4 operates in the low and medium frequency bands, and the vibrating part 3 operates in the medium and high frequency bands, so that the sound performance of the smart wearable glasses 100 provided by the present invention is improved. The vibrating part 3 and the sound generation unit 4 form complementary frequency bands, realizing wide-frequency sound reproduction in the low-frequency band and the medium and high-frequency band of the smart wearable glasses 100, with a wide frequency band and good sound performance. At the same time, the vibrating part 3 supplements the sound generation unit 4 in the low-frequency sound band, so that the sound generation unit 4 can enhance the low-frequency effect without increasing the size, 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 experience effect.

[0068] Hereinafter, the prototype smart wearable glasses 100 according to Example 1 are actually measured and compared and explained by actual measurement curves.

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

[0070] As shown in FIG. 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 in the related art. The smart wearable glasses 100 according to Example 1 of the present invention are different from the smart wearable glasses according to the related art in the following points.

[0071] Compared with the related-art smart wearable glasses, as can be obtained from FIG. 10, the smart wearable glasses 100 according to the first embodiment of the present invention add configurations corresponding to the first leakage hole 405 and the first inverse-phase hole 404 respectively. Thereby, the smart wearable glasses 100 according to 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 FIG. 11, FIG. 11 is a diagram showing a comparison of the frequency relationship curves of the sound pressure level at the outer position of the user's ear by the 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 of the smart wearable glasses according to the related art.

[0073] In FIG. 11, W3 is the sound pressure level frequency curve at the inner position of the ear by the related-art smart wearable glasses, and W4 is the sound pressure level frequency curve at the 20 cm outer position of the ear by the smart wearable glasses 100. Compared with the related-art smart wearable glasses, the smart wearable glasses 100 according to the first embodiment of the present invention add configurations corresponding to the first leakage hole 405 and the first inverse-phase hole 404 respectively. As can be obtained from FIG. 11, the difference in the voice response heard by the users of W3 and W4 is large, greater than 25 dB between 100 Hz and 4 kHz, and the maximum difference value is more than 40 dB, and the sound leakage prevention effect is good. Note that in the frequency band above 4 kHz, since the vibrating components are mainly transmitted to the human ear by bone conduction, privacy can be extremely protected.

[0074] Summarizing the above points, the smart wearable glasses 100 provided by the present invention utilize the voice configuration of the inverse-phase tube 43 to significantly improve the low-frequency performance of the sound generation unit 4, and by the principle of sound wave inverse-phase cancellation, the low-frequency sound leakage in the sound generation unit 4 can be significantly reduced. The vibration unit 3 transmits sound directly to the ear through bone conduction by contact vibration, avoiding the sound leakage phenomenon, ensuring the privacy of medium and high frequencies, and reducing the sound leakage in the entire frequency band and enhancing the privacy, so that the user experience is improved, and the voice 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 FIGS. 12 and 13, FIG. 12 is a schematic diagram of the 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 the partial three-dimensional component decomposition of the template and the sound generation 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 the two are as follows.

[0077] The template 2a includes a second template main body 21a extending from the frame 1a, and a second template cover 22a covered and fixed on the second template main body 21a, and together with the second template main body 21a, surrounding to form a second sound chamber 20a.

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

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

[0080] The first sound hole 403a, the first out-of-phase 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 integrally designed with the temple 2a. According to such a configuration, the manufacturing process is simplified, the cost is reduced, and the weight and volume of the smart wearable glasses 100a are reduced. Therefore, the miniaturization and weight reduction of the smart wearable glasses 100a according to the second embodiment are good, and the user experience can be improved.

[0082] As described above, according to the configurations 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. According to the principle of sound wave out-of-phase cancellation, the sound leakage in the low frequency of the sound generating unit can be greatly reduced. Furthermore, the vibration unit transmits sound to the ear by direct contact vibration through bone conduction, avoiding the sound leakage phenomenon, and ensuring the privacy in the medium and high frequency bands, thereby realizing the reduction of sound leakage and the improvement of privacy in the entire frequency band, and the user experience is good. Therefore, the voice performance of the smart wearable glasses provided by the present invention is good.

[0083] Compared with related technologies, the smart wearable glasses provided by the present invention are configured to provide a sound generating part and a vibrating part in the temple. The housing of the sound generating part is provided with an anti-phase passage and a first anti-phase hole, an anti-phase tube is installed in the anti-phase passage, and the anti-phase tube sequentially passes through the anti-phase passage and the first anti-phase hole to communicate with the outside. Thus, the sound configuration using the anti-phase tube can greatly improve the low-frequency performance of the sound generating part. The housing is provided with a housing space, a first sound emitting hole, and a first leakage hole. The sound generating unit divides the housing space into a front chamber and a combined rear chamber. The front chamber communicates with the outside through the first sound emitting hole, and the combined rear chamber communicates with the outside through the first leakage hole and the anti-phase tube respectively. The phase of the sound wave emitted by the sound generating part through the first sound emitting hole is opposite to the phase of the sound wave emitted by the sound generating part through the first leakage hole. This configuration uses the sound configurations of the first sound emitting hole and the first leakage hole, and according to the principle of sound wave anti-phase cancellation, greatly reduces the low-frequency sound leakage in the sound generating part. In addition, the vibrating part transmits sound to the ear through direct contact vibration by bone conduction, avoids the phenomenon of sound leakage, guarantees the privacy of medium and high frequencies, and improves the user experience by realizing the reduction of sound leakage and the improvement of privacy in the full frequency band. As a result, the smart wearable glasses provided by the present invention have good sound performance.

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