Description

Technical Field

[0001] This application belongs to the field of wearable device technology, and specifically relates to a wearable device. Background Technology

[0002] With the development of smart wearable technology, the demand for smart wearable devices such as Virtual Reality (VR) glasses, Augmented Reality (AR) glasses, and smart headphones is increasing. Different application scenarios require switching these devices to different audio modes. For example, when users use smart wearable devices in private indoor spaces, they prefer to use speaker mode to avoid head discomfort caused by prolonged wear; when users use smart wearable devices in public outdoor spaces, they prefer to use headphone mode to avoid sound leakage leading to privacy breaches or noise pollution.

[0003] In related technologies, the audio mode switching of smart wearable devices automatically adjusts the volume of the headphones based on changes in the position of the headphones in order to switch between different audio modes and meet the usage needs of different application scenarios.

[0004] However, the method of automatically adjusting the volume based on the position of the headphones in the relevant technology can lead to several problems. If the volume is turned down too much, the user may not be able to hear the audio clearly. If the volume is turned down too little, it may cause sound leakage and privacy breaches. Summary of the Invention

[0005] This application aims to provide a wearable device that at least solves the problem in related technologies where the volume is automatically adjusted based on the position of the headphones, which can easily lead to sound leakage and privacy breaches when the headphones are in headphone mode.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides a wearable device, including: a device body and an audio module;

[0008] The audio module is movably connected to the device body and can move relative to the device body to switch between a first position and a second position. When the audio module is in the first position, the audio module is in speaker mode, and when the audio module is in the second position, the audio module is in headphone mode.

[0009] The audio module has a first sound outlet on its first side and a second sound outlet on its second side, with the first side and the second side opposite to each other. The audio module can emit a first audio signal from the first sound outlet and a second audio signal from the second sound outlet.

[0010] When the audio module is in the headphone mode, the first audio signal and the second audio signal are out of phase.

[0011] In the embodiments of this application, an audio module is movably connected to the device body. The audio module can move relative to the device body to switch between a first position and a second position. In the first position, the audio module is in speaker mode, and in the second position, it is in headphone mode. A first sound outlet and a second sound outlet are respectively provided on opposite sides of the audio module. The audio module can emit a first audio signal from the first sound outlet and a second audio signal from the second sound outlet. When the audio module is in headphone mode, the first and second audio signals emitted by the audio module are out of phase. Thus, when the position of the audio module is adjusted to be in headphone mode, at a distance from the audio module, the two out-of-phase audio signals cancel each other out, achieving a far-field noise cancellation effect and preventing sound leakage from the audio module in headphone mode. In this audio mode, since the human ear is closer to the first sound outlet, the first audio signal can be received from the first sound outlet, while the second audio signal emitted from the second sound outlet is transmitted outward without affecting the human ear's reception of the audio signal. At the same time, it also avoids the stimulation of the human ear by loud audio volume.

[0037] The wearable device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0038] like Figure 1 , Figure 2 and Figure 5 As shown, a wearable device according to some embodiments of this application includes: a device body 10 and an audio module 20; the audio module 20 is movably connected to the device body 10, and the audio module 20 can move relative to the device body 10 to switch between a first position and a second position. When the audio module 20 is in the first position, the audio module 20 is in speaker mode, and when the audio module 20 is in the second position, the audio module 20 is in headphone mode; a first sound outlet 211 is provided on a first side of the audio module 20, and a second sound outlet 212 is provided on a second side of the audio module 20, with the first side and the second side opposite to each other; the audio module 20 can emit a first audio signal from the first sound outlet 211 and a second audio signal from the second sound outlet 212, wherein, when the audio module 20 is in headphone mode, the first audio signal and the second audio signal are out of phase.

[0039] In this embodiment, the audio module 20 is movably connected to the device body 10. The audio module 20 can move relative to the device body 10 to switch between a first position and a second position. In the first position, the audio module 20 is in speaker mode, and in the second position, it is in headphone mode. A first sound outlet 211 and a second sound outlet 212 are respectively provided on opposite sides of the audio module 20. The audio module 20 can emit a first audio signal from the first sound outlet 211 and a second audio signal from the second sound outlet 212. When the audio module 20 is in headphone mode, the first and second audio signals emitted by the audio module 20 are out of phase. Thus, when the position of the audio module 20 is adjusted to be in headphone mode, at a distance far from the audio module 20, the two out-of-phase audio signals cancel each other out, achieving a far-field noise cancellation effect and preventing sound leakage from the audio module 20 in headphone mode. In this audio mode, since the human ear is close to the first sound outlet 211, it can receive the first audio signal from the first sound outlet 211, and the second audio signal emitted from the second sound outlet 212 is transmitted outward without affecting the human ear's reception of the audio signal. At the same time, it can also avoid the stimulation of the human ear by the loud audio volume.

[0040] Specifically, the wearable devices in this application embodiment include, but are not limited to: VR glasses, AR glasses, MR glasses, smart headphones, smartwatches, etc. The wearable device is provided with a device body 10 and an audio module 20. The device body 10 is used to contact the human body when the user wears it, and the audio module 20 is used to emit the audio signal required by the user.

[0041] The audio module 20 is movably connected to the device body 10. The audio module 20 can move relative to the device body 10 so that the audio module 20 can switch between a first position and a second position. When the audio module 20 is in the first position, the audio module 20 is configured in external speaker mode. When the audio module 20 is in the second position, the audio module 20 is configured in headphone mode.

[0042] In practical applications, when the audio module 20 is in speaker mode, users can receive audio signals without wearing wearable devices. However, when the audio module 20 is in headphone mode, users need to wear wearable devices to receive audio signals. This can prevent sound leakage from causing privacy leaks or noise pollution.

[0043] Specifically, the audio module 20 includes a first side and a second side disposed opposite to each other. A first sound outlet 211 is provided on the first side of the audio module 20, and a second sound outlet 212 is provided on the second side of the audio module 20. The audio module 20 can emit a first audio signal from the first sound outlet 211 and a second audio signal from the second sound outlet 212. Furthermore, when the audio module 20 is in headphone mode, the first audio signal emitted by the audio module 20 is out of phase with the second audio signal.

[0044] Understandably, when using a wearable device, the first side of the audio module 20 can be positioned towards the user's ear, and the second side of the audio module 20 can be positioned away from the ear. Of course, the first and second sides of the audio module 20 can be set according to the actual usage requirements of the device, and there are no restrictions here.

[0045] In a specific application, when a user wears the wearable device, the audio module 20 is in headphone mode, with the first sound outlet 211 of the audio module 20 facing the user's ear. The first audio signal emitted by the audio module 20 is transmitted into the user's ear through the first sound outlet 211, and the second audio signal emitted by the audio module 20 is transmitted outward through the second sound outlet 212, so that the user can receive the audio signal while reducing the stimulation of the human ear caused by excessive volume.

[0046] Furthermore, when the audio module 20 is in headphone mode, the first audio signal emitted from the audio module 20 is out of phase with the second audio signal. This causes the two audio signals, at a distance slightly from the headphones, to cancel each other out. For example, if the first audio signal is in positive phase and the second audio signal is in negative phase, the two sound waves cancel each other out, achieving far-field noise reduction and preventing sound leakage from the audio module 20 in headphone mode.

[0047] It is understandable that the first audio signal and the second audio signal emitted by the audio module 20 are both AC signals. The two audio signals have the same frequency and the phase difference between the two audio signals is exactly 180°. At a certain moment, when one audio signal is in positive phase, the other audio signal is in negative phase.

[0048] In some embodiments, the number of first sound outlet holes 211 on the device body 10 can be multiple, and the multiple first sound outlet holes 211 are distributed in a honeycomb pattern. Correspondingly, the number of second sound outlet holes 212 can also be multiple, and the multiple second sound outlet holes 212 are distributed in a honeycomb pattern.

[0049] In some embodiments, when the audio module 20 is in the first position, the audio module 20 is attached to the device body 10, and the device body 10 blocks the first sound outlet 211 or the second sound outlet 212; when the audio module 20 is in the second position, the audio module 20 is at least partially detached from the device body 10, and the device body 10 releases the blocking of the first sound outlet 211 or the second sound outlet 212.

[0050] Specifically, the device body 10 may be provided with a storage slot. When the audio module 20 is in the first position, the audio module 20 can be stored in the storage slot. The audio module 20 is attached to the device body 10. The device body 10 blocks the first sound outlet 211 or the second sound outlet 212 of the audio module 20. The audio signal emitted by the audio module 20 is mainly transmitted outward through the unblocked sound outlet. At this time, the audio module 20 is in the external playback mode.

[0051] When switching to headphone mode is required, the audio module 20 is moved relative to the device body 10 to switch to a second position. In this second position, the audio module 20 is at least partially detached from the device body 10, and the device body 10 releases its obstruction of either the first sound outlet 211 or the second sound outlet 212. That is, both the first and second sound outlets of the audio module 20 are now obstructed. At this time, the first audio signal emitted by the audio module 20 is transmitted towards the ear through one of the two sound outlets, and the second audio signal emitted by the audio module 20 is transmitted outwards through the other sound outlet. At a distance from the audio module 20, the two audio signals with opposite phases cancel each other out, achieving a far-field noise cancellation effect. In this state, the audio module 20 is in headphone mode.

[0052] In some embodiments, one end of the audio module 20 is rotatably connected to the device body 10, and the audio module 20 can rotate relative to the device body 10 to switch between a first position and a second position. The first sound outlet 211 and the second sound outlet 212 are both located on opposite sides of the other end of the audio module 20, so that the relative positions of the first sound outlet 211 and the second sound outlet 212 with respect to the device body 10 can be changed by rotating the audio module 20.

[0053] Optionally, such as Figure 4As shown, the audio module 20 includes: a module housing 21 and an audio component 22; the module housing 21 is movably connected to the device body 10, a first sound outlet 211 is located on the first side of the module housing 21, and a second sound outlet 212 is located on the second side of the module housing 21; the audio component 22 is disposed inside the module housing 21, and the audio component 22 is connected to the first sound outlet 211 and the second sound outlet 212 respectively; the audio component 22 can emit a first audio signal from the first sound outlet 211 and a second audio signal from the second sound outlet 212, and when the audio module 20 is in headphone mode, the first audio signal and the second audio signal are out of phase.

[0054] In this embodiment, the audio component 22 is installed inside the module housing 21. The audio signal emitted by the audio component 22 can be transmitted outward from the first sound outlet 211 and the second sound outlet 212 provided on the module housing 21. By adjusting the position of the module housing 21 relative to the device body 10, different audio modes can be switched. When the audio module 20 is in headphone mode, the audio component 22 emits a first audio signal and a second audio signal with opposite phases, which can achieve a far-field noise cancellation effect and prevent the sound of the audio module 20 from leaking out in headphone mode.

[0055] Specifically, the audio module 20 includes a module housing 21 and an audio component 22. The module housing 21 is movably connected to the device body 10 and can move relative to the device body 10 to switch between a first position and a second position. The module housing 21 includes a first side and a second side disposed opposite to each other. A first sound outlet 211 is provided on the first side of the module housing 21, and a second sound outlet 212 is provided on the second side of the module housing 21.

[0056] An audio component 22 is installed inside the module housing 21. One end of the audio component 22 is connected to the first sound outlet 211, and the other end of the audio component 22 is connected to the second sound outlet 212. The audio component 22 simultaneously emits a first audio signal from the first sound outlet 211 and a second audio signal from the second sound outlet 212.

[0057] Furthermore, when the module housing 21 moves relative to the device body 10 to the second position, the audio module 20 is in headphone mode, and the audio component 22 emits a first audio signal and a second audio signal with opposite phases, which can achieve a far-field noise reduction effect.

[0058] It is understandable that when the module housing 21 is in the first position, the audio module 20 is in the external playback mode. Since the sound outlet on one side of the module housing 21 is blocked by the device body 10, the audio signal emitted by the audio component 22 is mainly transmitted outward through the sound outlet on the other side of the module housing 21. At a distance from the audio module 20, the audio signal can be received, thus realizing the external playback of sound.

[0059] Optionally, such as Figure 3 and Figure 4 As shown, the audio component 22 includes: a first audio unit 221; the first audio unit 221 is disposed inside the module housing 21, the first audio unit 221 has a first sound output end facing the device body 10 and a second sound output end facing away from the device body 10; the first sound output end is connected to a first sound output hole 211, and the second sound output end is connected to a second sound output hole 212; a controller is connected to the first audio unit 221, the controller is used to control the first sound output end to emit a first audio signal, and the second sound output end to emit a second audio signal, and the first audio signal and the second audio signal are out of phase.

[0060] In this embodiment, the audio component 22 is configured as a first audio unit 221, which is installed inside the module housing 21. The two opposite ends of the first audio unit 221 are connected to a first sound outlet 211 and a second sound outlet 212 on the module housing 21, respectively. This allows the first audio unit 221 to emit audio signals with opposite phases from the first sound outlet 211 and the second sound outlet 212. This achieves far-field noise cancellation when the audio module 20 is in headphone mode, preventing sound leakage from the audio module 20 in headphone mode. Simultaneously emitting audio signals in two directions from a single audio unit also facilitates practical operation and control.

[0061] Specifically, the first audio unit 221 can be a single-vibration sound source. The first audio unit 221 is disposed inside the module housing 21. The first audio unit 221 includes a first sound-emitting end and a second sound-emitting end disposed opposite to each other. The first sound-emitting end is connected to a first sound-emitting hole 211 on the module housing 21, and the first audio signal emitted from the first sound-emitting end is transmitted towards the device body 10 through the first sound-emitting hole 211. The second sound-emitting end is connected to a second sound-emitting hole 212 on the module housing 21, and the second audio signal emitted from the second sound-emitting end is transmitted away from the device body 10 through the second sound-emitting hole 212.

[0062] The first audio unit 221 can simultaneously emit audio signals with opposite phases from the first sound output end and the second sound output end. For example, the first audio unit 221 emits a positive-phase audio signal from the first sound output hole 211 and a negative-phase audio signal from the second sound output hole 212, or emits a negative-phase audio signal from the first sound output hole 211 and a positive-phase audio signal from the second sound output hole 212.

[0063] In practical applications, when the audio module 20 is in headphone mode, at a distance from the wearable device, the two audio signals with opposite phases emitted by the first audio unit 221 cancel each other out, achieving a noise reduction effect. However, when the audio module 20 is in speaker mode, the module housing 21 is in the first position, and one of the first sound outlet 211 and the second sound outlet 212 is blocked by the device body 10. The audio signal received at a distance from the audio module 20 is primarily the audio signal emitted by the other of the first and second sound outlets, thus avoiding the cancellation effect and achieving external sound output.

[0064] In some embodiments, a sealed first sound cavity is provided within the module housing 21 at a position corresponding to the first sound output end, and a first sound output hole 211 communicates with the first sound cavity. Correspondingly, a sealed second sound cavity is provided within the module housing 21 at a position corresponding to the second sound output end, and a second sound output hole 212 communicates with the second sound cavity. By providing the first and second sound cavities within the module housing 21, the sound effects of the first and second audio signals can be enhanced accordingly, thereby strengthening the first and second audio signals.

[0065] In some embodiments, such as Figure 3 As shown, a dustproof net 224 is provided at the end of the first sound outlet 211 facing the first sound cavity. Similarly, a dustproof net 224 is also provided at the end of the second sound outlet 212 facing the second sound cavity. By setting the dustproof net 224, external impurities are prevented from entering the first sound cavity or the second sound cavity and affecting the sound output of the first audio unit 221, thus achieving protection for the first audio unit 221.

[0066] Optionally, such as Figure 7 and Figure 8 As shown, a cavity 11 for arranging components is provided inside the device body 10. The cavity 11 has an opening at a position corresponding to the audio module 20. When the audio module 20 is in external speaker mode, the first sound outlet 211 is connected to the opening of the cavity 11. When the audio module 20 is in headphone mode, the first sound outlet 211 is offset from the opening of the cavity 11.

[0067] In this embodiment, the device body 10 is provided with a cavity 11 for arranging components. By setting an opening in the cavity 11 at a position corresponding to the audio module 20, when the audio module 20 is in external playback mode, the first sound outlet 211 of the module housing 21 can be connected to the opening of the cavity 11. Thus, the first audio signal emitted by the first audio unit 221 enters the cavity 11 through the first sound outlet 211. The cavity 11 can be used as a speaker for the first audio signal, thereby amplifying the sound of the first audio signal and improving the sound effect of the audio module 20 in external playback mode.

[0068] Specifically, a cavity 11 is provided in the device body 10, which is typically used to house the components required for the wearable device. Further, an opening is provided on the cavity 11, and the position of the opening corresponds to the position of the audio module 20. The first sound outlet 211 is located on the side of the module housing 21 facing the device body. When the module housing 21 is in the first position, it fits snugly against the device body 10, and the first sound outlet 211 on the module housing 21 corresponds precisely to the opening of the cavity 11. Therefore, the cavity 11 on the device body 10 can be used as the speaker cavity for the first sound outlet of the audio module 20, thereby enhancing the first audio signal emitted from the first sound outlet. Even with partial positive and negative phase sound wave cancellation in the far field, far-field audio reception is still guaranteed, realizing the external amplification of the audio module 20's sound.

[0069] When the audio module 20 is in headphone mode, and the module housing 21 is in the second position, the first sound outlet 211 is detached from the device body 10, meaning the first sound outlet 211 is misaligned with the opening of the cavity 11. The first audio signal emitted by the first audio unit 221 from the first sound outlet 211 is transmitted towards the ear, while the second audio signal emitted from the second sound outlet 212 is transmitted outwards. Because the first and second audio signals are out of phase, a far-field noise cancellation effect is achieved.

[0070] In some embodiments, powdered sound-absorbing material particles may be filled into the cavity 11 of the device body 10 to increase the sound amplification effect of the cavity 11.

[0071] Optionally, the wearable device further includes: an adjustment component 40; the adjustment component 40 is movably connected between the device body 10 and the module housing 21, the module housing 21 being movable relative to the device body 10 to drive the adjustment component 40 to move at least partially relative to the opening of the cavity 11; when the audio module 20 is in headphone mode, the adjustment component 40 at least partially covers the opening of the cavity 11; when the audio module 20 is in speaker mode, the adjustment component 40 releases the obstruction of the opening.

[0072] In this embodiment, by providing an adjustment component 40 between the device body 10 and the module housing 21, the adjustment component 40 can be at least partially moved as the module housing 21 moves relative to the device body 10. Thus, when the module housing 21 moves to the second position, the audio module 20 is in headphone mode, and the adjustment component 40 at least partially covers the opening of the cavity 11, thus blocking the opening and preventing external impurities from entering the cavity 11 and affecting its amplification effect. When the module housing 21 moves to the first position, the audio module 20 is in external speaker mode, and the adjustment component 40 releases the obstruction of the opening, allowing the first sound outlet 211 on the module housing 21 to connect with the cavity 11, thereby amplifying the first audio signal using the cavity 11.

[0073] Optionally, such as Figures 6 to 9 As shown, the adjustment component 40 includes: a baffle 41, a slide rod 42, and a connector 43; the device body 10 is provided with a slide groove 12, and the slide rod 42 is slidably connected to the slide groove 12; one end of the slide rod 42 is connected to the baffle 41, and the other end of the slide rod 42 is movably connected to the connector 43, and the end of the connector 43 away from the slide rod 42 is fixedly connected to the module housing 21; one end of the module housing 21 is rotatably connected to the device body 10, and the module housing 21 can rotate relative to the device body 10; during the rotation of the module housing 21 relative to the device body 10, the module housing 21 drives the slide rod 42 to move through the connector 43, and the slide rod 42 drives the baffle 41 to block or release the blocking of the opening.

[0074] In this embodiment, one end of the slide rod 42 is connected to the baffle 41, and the other end of the slide rod 42 is movably connected to the connector 43. The connector 43 is connected to the module housing 21. During the rotation of the module housing 21 relative to the device body 10, the module housing 21 can drive the slide rod 42 to slide within the slide groove 12 of the device body 10 via the connector 43. This causes the slide rod 42 to move the baffle 41 relative to the opening of the cavity 11. When the module housing 21 rotates to the second position, i.e., when the audio module 20 is in headphone mode, the slider drives the baffle 41 to block the opening of the cavity 11. When the module housing 21 switches to the first position, i.e., when the audio module 20 is in external speaker mode, the slider drives the baffle 41 to release the obstruction of the opening of the cavity 11, allowing the first sound outlet 211 to connect with the cavity 11, thus realizing the linkage between the adjustment component 40 and the module housing 21.

[0075] Specifically, the device body 10 may be provided with a rotating shaft, one end of the module housing 21 is rotatably connected to the rotating shaft, and the other end of the module housing 21 is provided with a first sound outlet 211 and a second sound outlet 212. The connector 43 may be connected to the end of the module housing 21 near the device body 10, and when the module housing 21 rotates relative to the rotating shaft, it may drive the connector 43 to move relative to the device body 10.

[0076] By rotatably connecting the connector 43 to one end of the slide rod 42, the slide rod 42 is slidably connected within the slide groove 12 on the device body 10. Movement of the connector 43 causes the slide rod 42 to slide within the slide groove 12. A baffle 41 is provided at the end of the slide rod 42 away from the connector 43, and the baffle 41 is positioned opposite the opening of the cavity 11. The slide groove 12 is located between the opening of the cavity 11 and the rotating shaft, so that movement of the slide rod 42 within the slide groove 12 causes the baffle 41 to move closer to or further away from the opening of the cavity 11.

[0077] In some embodiments, the structural shape of the slide rod 42 can be set according to the relative position of the opening of the cavity 11 on the device body 10 and the rotating shaft. The slide rod 42 can be a straight rod or a curved rod, and the shape of the sliding groove 12 on the device body 10 is adapted to the slide rod 42. The specific structure of the slide rod 42 and the sliding groove 12 can be set according to actual needs, and the embodiments of this application do not limit this.

[0078] In some embodiments, an annular seal may be provided around the opening of the cavity 11. When the module housing 21 is switched to the second position, the baffle 41 may cover the opening of the cavity 11 and abut against the annular seal to increase the sealing between the baffle 41 and the device body 10 and improve the shielding effect of the baffle 41 on the cavity 11.

[0079] Optionally, such as Figure 8 and Figure 9 As shown, the connector 43 has a limiting groove 431 at one end near the slide rod 42, and the slide rod 42 has a limiting protrusion 421, which is slidably connected to the limiting groove 431.

[0080] In this embodiment, by setting a limiting groove 431 at one end of the connector 43 near the slide rod 42, the upper limit protrusion 421 of the slide rod 42 is slidably connected to the limiting groove 431. Thus, during the rotation of the module housing 21 relative to the device body 10, the connector 43 can be driven to move in an arc relative to the device body 10. Through the cooperation of the limiting protrusion 421 and the limiting groove 431, the arc movement of the connector 43 can be converted into the horizontal movement of the slide rod 42, realizing the transmission of force, so that the overall movement of the adjustment component 40 is smoother.

[0081] In some embodiments, the extending direction of the limiting groove 431 is consistent with the extending direction of the connector 43, so that during the rotation of the connector 43, the limiting protrusion 421 can move freely in the limiting groove 431, and at the same time, the curvilinear motion force of the connector 43 can be converted into the horizontal movement force of the slide rod 42.

[0082] Optionally, such as Figures 10 to 13As shown, the audio component 22 includes a second audio unit 222 and a third audio unit 223; both the second audio unit 222 and the third audio unit 223 are disposed within the module housing 21; the second audio unit 222 is connected to the first sound outlet 211, and the second audio unit 222 can emit a first audio signal from the first sound outlet 211; the third audio unit 223 is connected to the second sound outlet 212, and the third audio unit 223 can emit a second audio signal from the second sound outlet 212; wherein, when the audio module 20 is in external speaker mode, the first audio signal and the second audio signal are in phase; when the audio module 20 is in headphone mode, the first audio signal and the second audio signal are out of phase.

[0083] In this embodiment, the audio component 22 may include a second audio unit 222 and a third audio unit 223. The second audio unit 222 emits a first audio signal through a first sound outlet 211, and the third audio unit 223 emits a second audio signal through a second sound outlet 212. When the audio module 20 is in speaker mode, the first audio signal and the second audio signal are in phase, thus the two audio signals with the same phase are superimposed to achieve a sound-speaking effect. When the audio module 20 is in headphone mode, the first audio signal and the second audio signal are in opposite phase. At a distance from the audio module 20, the positive and negative phase audio signals cancel each other out, achieving a far-field noise reduction effect.

[0084] Specifically, by simultaneously installing a second audio unit 222 and a third audio unit 223 within the module housing 21, with the output end of the second audio unit 222 facing the first sound outlet 211, the first audio signal emitted by the output end of the second audio unit 222 is transmitted through the first sound outlet 211. The output end of the third audio unit 223 faces the second sound outlet 212, and the second audio signal emitted by the output end of the third audio unit 223 is transmitted through the second sound outlet 212.

[0085] like Figure 13 As shown, when the audio module 20 is in external speaker mode, that is, when the module housing 21 is in the first position, the second audio unit 222 and the third audio unit 223 simultaneously emit audio signals with the same phase. The two audio signals with the same phase are transmitted outward from the first sound outlet 211 and the second sound outlet 212 respectively. At a distance from the audio module 20, the two audio signals with the same phase are received simultaneously. The two audio signals are superimposed on each other, which enhances the received audio signal and achieves the sound-speaking effect.

[0086] like Figure 14 and Figure 16As shown, when the audio module 20 is in headphone mode, that is, when the module housing 21 is in the second position, the second audio unit 222 and the third audio unit 223 simultaneously emit audio signals with opposite phases. The two audio signals with opposite phases are transmitted outward from the first sound outlet 211 and the second sound outlet 212 respectively. At a distance from the audio module 20, the two audio signals with opposite phases cancel each other out, achieving a far-field noise reduction effect.

[0087] In some embodiments, one of the second audio unit 222 and the third audio unit 223 can be configured as a fixed-phase sound source, and the other as a variable-phase sound source. For example, the second audio unit 222 can be configured as a fixed-phase sound source, always emitting a positive-phase audio signal, meaning the first audio signal is always a positive-phase audio signal. Simultaneously, the third audio unit 223 can be configured as a variable-phase sound source. When the audio module 20 is in headphone mode, the third audio unit 223 is controlled to emit a negative-phase audio signal; when the audio module 20 is in speaker mode, the third audio unit 223 is controlled to emit a positive-phase audio signal.

[0088] Of course, the phase settings of the audio signals emitted by the second audio unit 222 and the third audio unit 223 can be set according to actual needs, and this application embodiment does not limit this.

[0089] In some embodiments, a sealed first acoustic cavity is provided within the module housing 21 at a position corresponding to the sound output end of the second audio unit 222, and a first sound outlet 211 communicates with the first acoustic cavity. Correspondingly, a sealed second acoustic cavity is provided within the module housing 21 at a position corresponding to the sound output end of the third audio unit 223, and a second sound outlet 212 communicates with the second acoustic cavity. By providing the first and second acoustic cavities, the sound effects of the first and second audio signals can be enhanced accordingly, thereby strengthening the first and second audio signals.

[0090] In some embodiments, such as Figure 10 As shown, a dustproof net 224 is provided at the end of the first sound outlet 211 facing the first sound cavity. Similarly, a dustproof net 224 is also provided at the end of the second sound outlet 212 facing the second sound cavity. By setting the dustproof net 224, external impurities are prevented from entering the first sound cavity or the second sound cavity and affecting the sound output of the first audio unit 221, thus achieving protection for the first audio unit 221.

[0091] Optionally, such as Figure 10 and Figure 13As shown, the wearable device also includes: a sensing component 50; the sensing component 50 is disposed between the device body 10 and the module housing 21, and the sensing component 50 is used to sense the position change of the module housing 21 relative to the device body 10 to trigger a sensing signal; the second audio unit 222 and the third audio unit 223 are electrically connected to the sensing component 50 respectively, and the second audio unit 222 and the third audio unit 223 adjust the phase of the corresponding audio signal according to the sensing signal.

[0092] In this embodiment, a sensing component 50 is provided between the device body 10 and the module housing 21. The sensing component 50 can sense the position change of the module housing 21 and send corresponding sensing signals to the second audio unit 222 and the third audio unit 223. The second audio unit 222 and the third audio unit 223 emit audio signals with the same or opposite phase according to the sensing signals, so that the audio module 20 switches between different audio modes.

[0093] Optionally, such as Figure 10 As shown, the sensing component 50 includes a trigger 51 and a sensor 52; the trigger 51 is installed in one of the device body 10 and the module housing 21, and the sensor 52 is installed in the other of the device body 10 and the module housing 21; the sensor 52 is electrically connected to the second audio unit 222 or the third audio unit 223, and the sensor 52 is used to sense the position change of the trigger 51 to output a sensing signal to the second audio unit 222 or the third audio unit 223; the second audio unit 222 adjusts the phase of the first audio signal based on the sensing signal, or the third audio unit 223 adjusts the phase of the first audio signal based on the sensing signal.

[0094] In this embodiment, the sensing component 50 includes a trigger 51 and a sensor 52. The trigger 51 is installed in one of the device body 10 and the module housing 21, and the sensor 52 is installed in the other of the device body 10 and the module housing 21. During the movement of the module housing 21 relative to the device body 10, the module housing 21 drives the relative movement between the trigger 51 and the sensor 52. The sensor 52 then senses the position change of the trigger 51 and sends out a sensing signal. Based on the sensing signal, the second audio unit 222 and the third audio unit 223 respectively send out audio signals with the same phase or opposite phase.

[0095] Specifically, the trigger 51 can be mounted on the device body 10, and the sensor 52 can be mounted on the module housing 21, with the trigger 51 and the sensor 52 arranged opposite to each other; alternatively, the trigger 51 can be mounted on the module housing 21, and the sensor 52 can be mounted on the device body 10. As the module housing 21 moves relative to the device body 10, the sensor 52 can move closer to or further away from the trigger 51 to trigger the corresponding sensing signal.

[0096] In a specific application, when the module housing 21 moves to the first position, the sensor 52 triggers a first sensing signal. Based on the first sensing signal, the second audio unit 222 and the third audio unit 223 simultaneously emit audio signals with the same phase, so that the audio module 20 is in the external playback mode.

[0097] When the module housing 21 moves to the second position, the second sensing signal triggered by the sensor 52, based on the second sensing signal, the second audio unit 222 and the third audio unit 223 simultaneously emit audio signals with opposite phases, so that the audio module 20 is in headphone mode.

[0098] In some embodiments, the sensing element 52 can be a Hall sensor, and the trigger element 51 can be a magnetic element. The Hall sensor senses the change in the magnetic field of the magnetic element to trigger a corresponding sensing signal. Of course, other types of sensing elements 52 can also be used, and the trigger element 51 can be adapted to the sensing element 52. Those skilled in the art can make settings according to actual needs, and the embodiments of this application do not limit this.

[0099] Optionally, such as Figure 15 As shown, along the axial direction perpendicular to the first sound outlet 211, the module housing 21 is provided with a third sound outlet 213, which is connected to the first sound outlet 211.

[0100] In this embodiment, a third sound outlet 213 can be provided on the module housing 21, with the axis of the third sound outlet 213 perpendicular to the axis of the first sound outlet 211, and the third sound outlet 213 communicating with the first sound outlet 211. The first audio signal emitted by the second audio unit 222 can be transmitted outward simultaneously through the first sound outlet 211 and the third sound outlet 213. Thus, in headphone mode, the first sound outlet 211 is opposite to the ear, and the third sound outlet 213 is located near the ear, which can improve the audio effect received by the ear. At the same time, in speaker mode, the audio emitted by the audio module 20 is transmitted from multiple directions, which can also increase the sound output effect.

[0101] It is understandable that the first sound outlet 211 and the second sound outlet 212 are positioned opposite each other on the module housing 21, with the first sound outlet 211 facing the device body 10 and the second sound outlet 212 facing away from the device body 10, and the axes of the first sound outlet 211 and the second sound outlet 212 being parallel.

[0102] Furthermore, a third sound outlet 213 can be provided on the upper and lower sides of the module housing 21. The axis of the third sound outlet 213 is perpendicular to the axis of the first sound outlet 211, and the third sound outlet 213 is connected to the first sound outlet 211. Both the first sound outlet 211 and the third sound outlet 213 are connected to the second audio unit 222. The first audio signal emitted from the second audio unit 222 can be transmitted simultaneously through the first sound outlet 211 and the third sound outlet 213.
