[0057] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0058] Combine the following Figures 1 to 14 , through specific embodiments and application scenarios, the wearable device provided by the embodiment of the utility model is described in detail.

[0059] like Figures 1 to 6 As shown, an embodiment of the utility model provides a wearable device, including: a device body 1 and a sound unit 10.

[0060] The device body 1 is provided with a sound cavity, a first sound outlet hole 1201 and a second sound outlet hole 1202 ; the sound unit 10 is provided in the device body 1 and is configured to emit sound toward the sound cavity.

[0061] The sound cavity is communicated with the first sound outlet hole 1201 and the second sound outlet hole 1202 respectively, and the sound outlet directions of the first sound outlet hole 1201 and the second sound outlet hole 1202 are opposite.

[0062] It is understandable that the wearable device may be smart glasses, headphones, helmets, etc., which are well known in the art. The device body 1 is adaptively configured in structure and shape according to the type of wearable device, which will not be described in detail here.

[0063] The sound unit 10 can be configured to be detachably installed in the device body 1 and located at a position of the device body 1 close to the human auricle; a sound cavity is formed between the sound output side of the sound unit 10 and the inner wall of the device body 1 to ensure that the sound unit 10 can emit sound directly into the sound cavity.

[0064] like Figure 7 As shown, the sound unit 10 includes a speaker 101 and a first bracket 102. The first bracket 102 is frame-shaped. An installation area 1021 is formed on the inner side of the first bracket 102. The speaker 101 is arranged in the installation area 1021. The first bracket 102 is detachably arranged in the device body 1.

[0065] like Figure 8 As shown, the side wall of the first bracket 102 is provided with a first opening 1022 and a second opening 1023. The first opening 1022 is a part of the first sound hole 1201, and the first opening 1022 corresponds to the first docking hole on the device body 1 to form the first sound hole 1201; the second opening 1023 is a part of the second sound hole 1202, and the second opening 1023 corresponds to the second docking hole on the device body 1 to form the second sound hole 1202.

[0066] The sound emitting directions of the first sound hole 1201 and the second sound hole 1202 can be set opposite to the horizontal plane, the vertical plane, or the inclined plane, and there is no specific limitation on this.

[0067] For the wearable device shown in this embodiment, a sound unit 10 is configured based on the device body 1, and a first sound outlet 1201 and a second sound outlet 1202 with opposite sound outlet directions are arranged along the sound emission direction of the sound unit 10. After the wearer wears the wearable device, the sound emitted by the sound unit 10 is simultaneously distributed to the first sound outlet 1201 and the second sound outlet 1202 through the sound cavity, and then under the guidance of the first sound outlet 1201 and the second sound outlet 1202, the sound is output in the form of opposite phases, and then interferes and cancels each other outside the device body 1, ensuring that only the wearer can hear the sound emitted by the device, and other people beyond a certain range of the wearable device cannot hear the sound emitted by the device.

[0068] It can be seen that the wearable device shown in the present invention effectively prevents the sound played by the device from spreading outward, reduces the noise generated outward when the device plays audio, and reduces the risk of user privacy leakage.

[0069] In some embodiments, Figure 3 As shown, the device body 1 is also provided with a sound leakage hole 1203, and the sound leakage hole 1203 is connected to the sound cavity.

[0070] It is understandable that, by providing the sound leakage hole 1203, this embodiment can avoid or weaken the resonance of the sound emitted by the sound unit 10 in the sound cavity, which may affect the audio playback effect of the wearable device.

[0071] In order to ensure effective sound leakage, the sound leakage direction of the sound leakage hole 1203 in this embodiment is opposite to the sound emission direction of one of the first sound emission hole 1201 and the second sound emission hole 1202 .

[0072] Alternatively, if Figure 3 and Figure 4 As shown, in this embodiment, the sound leakage direction of the sound leakage hole 1203 is opposite to the sound emission direction of the first sound emission hole 1201.

[0073] like Figure 7 and Figure 8 As shown, the side wall of the first bracket 102 is further provided with a third opening 1024 , and the third opening 1024 serves as a part of the sound leakage hole 1203 . The third opening 1024 corresponds to the third docking hole on the device body 1 to form the sound leakage hole 1203 .

[0074] In some embodiments, Figure 7 As shown, at least one of the first sound outlet hole 1201 and the second sound outlet hole 1202 is provided with a first dustproof member 103 , and the first dustproof member 103 is configured to allow sound signals to pass through and prevent dust from entering the sound cavity.

[0075] And / or, the sound leakage hole 1203 is provided with a second dustproof piece 104, and the second dustproof piece 104 is configured to allow sound signals to pass through and prevent dust from entering the sound cavity.

[0076] Specifically, in this embodiment, both the first sound outlet 1201 and the second sound outlet 1202 are provided with a first dustproof part 103, and the sound leakage hole 1203 is provided with a second dustproof part 104. This design is conducive to achieving dust-proof sealing for the sound unit 10, thereby ensuring the audio playback quality of the device.

[0077] The first dustproof member 103 and the second dustproof member 104 may be configured as the same structure, and may be configured to include a dustproof net 1031 and a decorative net 1032 . The dustproof net 1031 and the decorative net 1032 are sequentially arranged along the generating direction of the sound unit 10 .

[0078] like Figure 7 As shown, at the first sound outlet 1201 , the dustproof net corresponding to the first dustproof piece 103 is installed on the first opening 1022 on the first bracket 102 , and the decorative net corresponding to the first dustproof piece 103 is installed on the first docking hole on the device body 1 .

[0079] At the second sound outlet 1202 , the dustproof net 1031 corresponding to the first dustproof member 103 is installed on the second opening 1023 on the first bracket 102 , and the decorative net 1032 corresponding to the first dustproof member 103 is installed on the second docking hole on the device body 1 .

[0080] At the sound leakage hole 1203 , the dustproof net 1031 corresponding to the second dustproof piece 104 is installed on the third opening 1024 on the first bracket 102 , and the decorative net 1032 corresponding to the second dustproof piece 104 is installed on the third docking hole on the device body 1 .

[0081] In some embodiments, Figure 2 , Figure 4 and Figure 5 As shown, the wearable device further includes: a sound pickup unit 20 and a control module 30.

[0082] The sound pickup unit 20 is electrically connected to the control module 30, and the control module 30 is electrically connected to the sound generating unit 10. The sound pickup unit 20 is configured to collect the environmental noise signal, and the control module 30 is configured to perform inversion processing on the environmental noise signal to obtain an inverted noise signal; the sound generating unit 10 is configured to play the inverted noise signal under the control of the control module 30.

[0083] It is understandable that when the sound unit 10 of the wearable device plays audio, in order to prevent or reduce the wearer from hearing environmental noise, the sound pickup unit 20 automatically picks up the noise in the surrounding environment and plays sound waves with opposite phases through the sound unit 10 to offset the noise in the environment, thereby improving the wearer's auditory environment.

[0084] The control module 30 may adopt a single chip microcomputer known in the art, and perform inversion processing on the environmental noise signal through an inverter.

[0085] In some embodiments, Figure 3 , Figure 5 , Figure 6 and Fig. 9 As shown, the sound pickup unit 20 is disposed in the device body 1 and is arranged opposite to the sound pickup hole 1204 on the device body 1 so as to collect the ambient noise signal of the surrounding environment through the sound pickup hole 1204 .

[0086] At the same time, the sound pickup unit 20 and the sound emitting unit 10 are isolated and arranged in the device body 1 to prevent the sound emitted by the sound emitting unit 10 from being transmitted from the device body 1 to the sound pickup unit 20, thereby ensuring that the sound pickup unit 20 accurately collects the ambient noise signal, so that the device can perform noise reduction processing on the sound played by the sound emitting unit 10 based on the ambient noise signal.

[0087] In some embodiments, Fig. 9 and Fig.10 As shown, the sound pickup hole 1204 is provided with a third dustproof piece 203 , and the third dustproof piece 203 is configured to allow sound signals to pass through and prevent dust from reaching the sound pickup end of the sound pickup unit 20 through the sound pickup hole 1204 .

[0088] It is understandable that, in this embodiment, by providing the third dustproof member 203 in the sound pickup hole 1204, dustproof sealing of the sound pickup unit 20 can be achieved, which is beneficial to ensuring the acoustic quality of the entire device.

[0089] like Fig.10 and Fig.11 As shown, the sound pickup unit 20 includes a sound pickup 201 and a second bracket 202 . The sound pickup 201 can adopt an omnidirectional microphone known in the art. The second bracket 202 is detachably arranged in the device body 1 , and a first groove 2021 and a second groove 2022 are provided on the second bracket 202 .

[0090] The first groove 2021 is provided on the surface of the second bracket 202 and is used to realize the layout of the flexible circuit board 70. The flexible circuit board 70 is electrically connected to the pickup 201. The second groove 2022 is provided at the notch 2023 on the side of the second bracket 202 and is arranged opposite to the sound pickup hole 1204. The pickup 201 is provided in the second groove 2022, and the sound pickup end of the pickup 201 faces the sound pickup hole 1204.

[0091] At the same time, the third dustproof member 203 is similar to the first dustproof member 103 and the second dustproof member 104, and can be configured to include a dustproof net and a decorative net, and the pickup 201, the dustproof net and the decorative net are arranged in sequence from the inside to the outside.

[0092] Among them, the third dustproof part 203, the flexible circuit board 70 and the second bracket 202 cooperate to realize the encapsulation of the pickup 201 in the second groove 2022; at the same time, this embodiment arranges the second groove 2022 at the notch 2023 on the side of the second bracket 202, so that the wearer can observe whether the pickup 201 is installed in the second groove 2022 at the notch 2023.

[0093] In some embodiments, Figure 2 As shown, the wearable device further includes: a wireless communication module 40 ; the wireless communication module 40 is configured to receive an audio signal from the terminal device 100 and transmit the audio signal to the control module 30 .

[0094] The control module 30 is configured to perform mixing processing on the audio signal and the anti-phase noise signal, and control the sound unit 10 to play the audio signal after the mixing processing.

[0095] It is understandable that the wireless communication module 40 can adopt a Bluetooth module, a WiFi module, a 4G module or a 5G module known in the art, and there is no specific limitation on this.

[0096] The wireless communication module 40 can establish a communication connection with a terminal device 100 such as a smart phone, a tablet computer, a laptop computer, a desktop computer, etc. through wireless communication.

[0097] The wireless communication module 40 is electrically connected to the control module 30, and the control module 30 is electrically connected to the sound unit 10. Thus, in practical applications, when the control module 30 receives the audio signal from the wireless communication module 40 and the anti-phase noise signal from the sound pickup unit 20, the control module 30 can use an audio mixing algorithm known in the art or a matrix digital mixer to mix the two audio signals to obtain a mixed audio signal, and then control the sound unit 10 to play the mixed audio signal.

[0098] Since the anti-phase noise signal has an opposite phase to the ambient noise signal in the environment, the sound waves corresponding to the anti-phase noise signal in the sound played by the sound unit 10 will interfere with the surrounding noise, weaken or even offset the surrounding noise, improve the wearer's auditory environment, and ensure that the wearer can clearly hear the audio signal from the wireless communication module 40.

[0099] Based on the above settings, the wearable device shown in this embodiment can realize functions such as voice broadcasting, music playing, and making and receiving calls, thereby enhancing the human-computer interaction experience.

[0100] In some embodiments, Figure 1 As shown, the wearable device is a smart glasses. The following takes the smart glasses as an example to further illustrate the solution shown in the utility model.

[0101] like Figures 1 to 6 As shown, the smart glasses include a frame 11 and temples 12 , the head ends of the temples 12 are rotatably connected to the frame 11 , and the sound-generating unit 10 and the sound-collecting unit 20 are respectively disposed in the temples 12 .

[0102] Specifically, the sound pickup unit 20 is arranged on the temple 12 close to the frame 11, and the sound unit 10 is configured to be arranged near the position where the temple 12 contacts the human auricle, so that the wearer can clearly hear the sound played by the sound unit 10.

[0103] The main body of the frame 11 is made of titanium alloy, including a silicone nose tip, a nose tip bracket and lenses, etc. There are two lenses, and filter lenses, myopia lenses, presbyopia lenses, etc. can be customized according to needs.

[0104] Two temples 12 are provided, one of the two temples 12 is rotatably connected to one end of the frame 11, and the other of the two temples 12 is rotatably connected to the other end of the frame 11. The temples 12 and the frame 11 may be hinged by screws or bolts.

[0105] The temple 12 includes a first straight segment, an arc segment and a second straight segment, which are connected in sequence. The end of the first straight segment away from the arc segment serves as the head end of the temple 12 and is rotatably connected to one end of the frame 11. The arc segment is used to be placed at the root of the human auricle, and the end of the second straight segment away from the arc segment serves as the tail end of the temple 12.

[0106] The sound pickup unit 20 is disposed at an end of the first straight line segment away from the arc segment, and the sound generating unit 10 is disposed at an end of the first straight line segment close to the arc segment.

[0107] In some embodiments, Figure 3 and Figure 4As shown, the first sound outlet hole 1201 is disposed on the top surface of the temple 12 , and the second sound outlet hole 1202 is disposed on the bottom surface of the temple 12 .

[0108] The sound emission direction of the sound emitting unit 10 is toward the outer side surface of the temple 12 and is perpendicular to the sound emission directions of the first sound emission hole 1201 and the second sound emission hole 1202 .

[0109] It is understandable that when the wearer wears the smart glasses, the sound-generating end of the sound-generating unit 10 faces the side of the temple 12 away from the wearer's head, which makes the sound-generating direction of the sound-generating unit 10 along the horizontal direction and toward the side away from the wearer's head.

[0110] After the sound unit 10 emits sound into the sound cavity, under the guidance of the first sound outlet hole 1201 and the second sound outlet hole 1202, the sound emitted by the sound unit 10 is output from the upper and lower sides of the temple 12 in the form of opposite phases, that is, the upper and lower diversion of the sound is achieved, ensuring that most of the sound emitted by the device interferes with the side (left or right) of the human head, which not only makes only the wearer able to hear the sound emitted by the device, while other people in the surrounding environment cannot hear the sound, but also helps to improve the wearer's listening effect to the audio and prevent fatigue or other discomfort caused by long-term listening.

[0111] In some embodiments, Figures 3 to 6 As shown, the temple 12 includes a shell 121 and a spacer 122 disposed in the shell 121 .

[0112] The spacer 122 is used to separate the internal space of the housing 121 into a first accommodating area and a second accommodating area; the sound generating unit 10 is arranged in the first accommodating area, and the sound pickup unit 20 is arranged in the second accommodating area.

[0113] Specifically, the shell 121 can be injection molded by PC material. The shell 121 includes a first shell 1211 and a second shell 1212. The first shell 1211 is provided with a first clamping portion 12110 on the side facing the second shell 1212, and the second shell 1212 is provided with a second clamping portion 12120 on the side facing the first shell 1211. The first clamping portion 12110 and the second clamping portion 12120 are clamped together to realize the first shell 1211 and the second shell 1212 being assembled into one to form a complete shell 121.

[0114] Among them, one of the first clamping portion 12110 and the second clamping portion 12120 can be configured as a clamping tongue, and one of the first clamping portion 12110 and the second clamping portion 12120 can be configured as a bayonet, and the clamping tongue can be clamped in the bayonet.

[0115] At the same time, the first clamping portion 12110 and the second clamping portion 12120 can also be used to limit the installation positions of the sound unit 10 , the sound pickup unit 20 , the control module 30 , the flexible circuit board 70 , the battery module 80 and other functional modules in the housing 121 .

[0116] like Figure 5 As shown, the spacer 122 of this embodiment is arranged on the side of the first shell 1211 facing the second shell 1212, and the spacer 122 and the first shell 1211 are an integrated structure. After the first shell 1211 and the second shell 1212 are assembled into one, isolated first and second accommodating areas are automatically formed in the shell 121.

[0117] Since the sound unit 10 is arranged in the first accommodating area and the sound pickup unit 20 is arranged in the second accommodating area, this design realizes the isolation of the sound pickup unit 20 and the sound unit 10 in the device body 1, which is beneficial to prevent the sound pickup unit 20 from being affected by the sound unit 10 during audio collection.

[0118] In some embodiments, Figure 5 and Figure 6 As shown, a flexible circuit board 70 and a battery module 80 are also provided in the temple 12; wherein the battery module 80 can adopt a lithium battery known in the art.

[0119] The flexible circuit board 70 is extended along the extension direction of the temple 12 , and the sound pickup unit 20 and the sound generating unit 10 are electrically connected to the control module 30 through the flexible circuit board 70 .

[0120] A charging interface 90 is disposed at the rear end of the temple 12 , and the charging interface 90 is electrically connected to the flexible circuit board 70 and the battery module 80 , respectively.

[0121] like Fig.13 and Fig.14 As shown, the battery module 80 is limited between multiple second clamping parts 12120, one side of the battery module 80 is bonded to the inner wall of the shell 121 by the backing glue, and the other parts of the battery module 80 are covered with foam 12101. The foam 12101 is clamped between the battery module 80 and the shell 121 in an interference fit manner to provide a buffer between the battery module 80 and the shell 121, thereby ensuring the reliability of fixing the battery module 80 and preventing the battery module 80 from shaking in the shell 121.

[0122] A battery management module may be provided between the charging interface 90 and the battery module 80 , and the battery management module is electrically connected to the control module 30 to implement charging management of the battery module 80 .

[0123] like Fig.13 and Fig.14As shown, the charging interface 90 includes a charging terminal 901, a fixing plate 902, a reinforcement plate 903 and a permanent magnet 904. The charging terminal 901 can be a copper terminal. Two charging terminals 901 are provided. One end of the two charging terminals 901 is exposed at the tail end of the temple 12, and the other ends of the two charging terminals 901 are electrically connected to the flexible circuit board 70 respectively.

[0124] The part of the flexible circuit board 70 connected to the charging terminal 901 is clamped between the reinforcement plate 903 and the fixed plate 902. The fixed plate 902 is fixed in the shell 121. The permanent magnet 904 is located on the side of the reinforcement plate 903 away from the fixed plate 902 and is distributed between the two charging terminals 901.

[0125] Among them, the fixing plate 902 and the reinforcing plate 903 can be configured as magnetic conductive plates, and a sealing ring is provided on the outer side of the charging terminal 901 to achieve sealing between the charging terminal 901 and the shell 121 of the temple 12.

[0126] In actual applications, the charging interface 90 shown in this embodiment is configured to be electrically connected to the Pogopin interface on the charging device. The permanent magnet 904 is used to adsorb with the magnetic part on the charging device to ensure that the charging terminal 901 is stably connected to the Pogopin interface. The fixing plate 902 is used to provide an installation reference for the charging terminal 901 to prevent the charging terminal 901 from retracting into the shell 121 after the charging interface 90 has been used for multiple charging operations, thereby ensuring the stability of the entire charging interface 90 structure.

[0127] In some embodiments, Figure 2 and Figure 3 As shown, an in-ear detection sensor 50 is provided on the surface of the temple 12, and the in-ear detection sensor 50 is configured to detect whether the wearer is wearing smart glasses. The control module 30 is configured to realize power on and off control of the smart glasses according to the detection signal fed back by the in-ear detection sensor 50.

[0128] It is understandable that, when the temple 12 is configured to include a first straight line segment, an arc segment, and a second straight line segment, the in-ear detection sensor 50 is disposed on the lower surface of the arc segment.

[0129] When the wearer wears the smart glasses, the in-ear detection sensor 50 directly contacts the root of the auricle of the human body and feeds back a detection signal to the control module 30, which controls the smart glasses to start up and run.

[0130] Correspondingly, when the wearer takes the smart glasses off the head, the in-ear detection sensor 50 will not feed back a detection signal to the control module 30, and the control module 30 will control the smart glasses to shut down.

[0131] In some embodiments, Figure 2 and Figure 3 As shown, at least one touch sensor 60 is provided on the surface of the temple 12 , and the touch sensor 60 is configured to receive the operation instructions of the wearer, and the control module 30 is configured to control the sound state of the sound unit 10 according to the operation instructions fed back by the touch sensor 60 .

[0132] It is understandable that when the wearer wears smart glasses, the wearer can touch the touch sensor 60 with his fingers. After sensing the touch of the human body, the touch sensor 60 feeds back operating instructions to the control module 30, and the control module 30 controls the sound state of the sound unit 10 accordingly.

[0133] Among them, three touch sensors 60 can be set, and the three touch sensors 60 are arranged side by side on the outer surface of the temple 12. After receiving a touch, the three touch sensors 60 are used to feedback the operation instructions of volume increase, volume decrease and recording control to the control module 30 respectively.
