Description

Technical Field

[0001] This application relates to the field of anti-interference technology for wearable devices, and in particular to a wearable device, a test fixture, and a test method. Background Technology

[0002] As smart wearable devices such as AI glasses become smaller and thinner, the layout of their internal electronic components is becoming increasingly compact. The speaker and touch module are two core human-computer interaction functions. When the speaker emits sound, it generates mechanical vibrations, which are transmitted through the temples and frame of the glasses. When the speaker and touch module are rigidly connected or too close together, the vibrations can cause the touch module to malfunction (Ghost Touch) or become unresponsive.

[0003] Meanwhile, during mass production, due to factors such as assembly tolerances, screw torque differences, and uneven glue application, there are slight differences in the internal stress state and structural coupling degree of each product. When vibration is transmitted, some products are severely affected, and products with large differences in coupling degree will exacerbate the impact of vibration.

[0004] Traditional functional testing tests speaker sound quality and touch functionality in isolation, failing to detect coupling interference issues that only appear in specific working scenarios (such as when the sound is emitted at high volume).

[0005] This shows that neither the product structure design nor the product testing can effectively guarantee product quality, resulting in defective products entering the market. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Wearable devices may include an acoustic unit and a touch unit, which correspond to the user's voice information interaction and touch interaction, respectively. When the acoustic unit plays sound, the vibration generated will be transmitted to the touch unit, affecting the touch unit, such as causing accidental touch or touch failure.

[0024] This application provides a wearable device and a test fixture, including a support structure, an acoustic unit, and a touch unit. The acoustic unit and the touch unit are disposed on the support structure. Through structural optimization, the acoustic unit can reduce the transmission of vibration to the touch unit. At the same time, the touch unit is provided with a detection information output port, which can be combined with the test fixture to detect whether there are quality problems in the wearable device when it is emitting sound. This achieves synergy between structural improvement and product testing, ensuring the quality of the wearable device.

[0025] The following description, in conjunction with the accompanying drawings, details the various structures of the wearable device and test fixture provided in the embodiments of this application, as well as the positional and connection relationships between these structures.

[0026] like Figure 1 and Figure 2 As shown in the embodiment of this application, the acoustic unit 20 includes a buffer device 21, which is disposed between the acoustic unit 20 and the support structure 10, and is used to buffer the vibration transmitted from the acoustic unit 20 to the support structure 10.

[0027] The acoustic unit 20, i.e., the loudspeaker, vibrates during operation. In product design, it is necessary to reduce the transmission of vibration to other structures, i.e., to minimize the impact of vibration on other structures. The vibration transmitted in this part can be referred to as harmful vibration. The technical solution of this application utilizes a buffer device 21 for mechanical filtering, blocking / attenuating the transmission of harmful vibration to other structures.

[0028] Continue to refer to Figure 1 and Figure 2As shown in the embodiment of this application, the acoustic unit 20 and the touch unit 30 are spaced apart on the support structure 10. The acoustic unit 20 and the touch unit 30 are two independent structures on the support structure 10, which reduces vibration transmission due to direct contact. The support structure 10 includes a mounting groove 11, which is the mounting position for the acoustic unit 20. The acoustic unit 20 is disposed in the mounting groove 11, and multiple buffer devices 21 are provided between the outer shell of the acoustic unit 20 and the mounting groove 11 to form a composite vibration isolation buffer structure.

[0029] In this embodiment, the structural form of the acoustic unit 20 is not limited. The top of the acoustic unit 20 is a diaphragm, and its perimeter and bottom include rigid material. The rigid material can be the shell structure of the acoustic unit 20 or other rigid components of the acoustic unit 20, which can be collectively referred to as the outer shell. A composite vibration isolation and buffer structure is provided between the rigid material and the mounting groove 11.

[0030] like Figure 1 and Figure 2 As shown in the embodiment of this application, the buffer device 21 includes an elastic buffer bracket 211; one end of the elastic buffer bracket 211 is connected to the outer shell of the acoustic unit 20, and the other end is connected to the inner wall of the mounting groove 11.

[0031] For example, the elastic buffer bracket 211 has a certain extension stroke. When the acoustic unit 20 vibrates, the elastic buffer bracket 211 will absorb part of the vibration, avoiding / reducing the vibration transmission to the mounting groove 11, that is, avoiding / reducing the vibration transmission to the support structure 10 and the touch unit 30.

[0032] For example, the elastic buffer bracket 211 is filled between the acoustic unit 20 and the inner wall of the mounting groove 11. The elastic buffer bracket 211 includes a vibration damping space. When the acoustic unit 20 vibrates by emitting sound, the structure between the vibration damping space and the acoustic unit 20 can deform in the direction of the vibration damping space to absorb part of the vibration generated by the acoustic unit 20. Alternatively, for example, the elastic buffer bracket 211 includes an elastic element. The elastic element can be an elastic structure such as cotton, spring, or rubber. For example, the elastic element can be arranged in a layered structure between the acoustic unit 20 and the inner wall of the mounting groove 11.

[0033] For example, the elastic buffer bracket 211 can be set at any position between the acoustic unit 20 and the inner wall of the mounting groove 11; or, for example, there can be multiple elastic buffer brackets 211, forming a stable support and buffer structure, such as multiple elastic buffer brackets 211 being evenly distributed at the installation position.

[0034] In this embodiment, the acoustic unit 20 is subjected to primary vibration filtering by setting the elastic buffer bracket 211. The composite vibration isolation and buffer structure also includes more levels of vibration filtering. In this embodiment, the buffer device 21 includes a damping buffer layer 212; the position of the damping buffer layer 212 is flexible, such as... Figure 2 In the state shown, a damping buffer layer 212 is provided between the elastic buffer bracket 211 and the inner wall of the mounting groove 11. The two sides of the damping buffer layer 212 are connected to the elastic buffer bracket 211 and the inner wall of the mounting groove 11, respectively, to buffer the vibration from the elastic buffer bracket 211 to the inner wall of the mounting groove 11. Alternatively, the damping buffer layer 212 can also be provided between the outer shell of the acoustic unit 20 and the elastic buffer bracket 211. The two sides of the damping buffer layer 212 are connected to the outer shell of the acoustic unit 20 and the elastic buffer bracket 211, respectively, to buffer the vibration from the outer shell of the acoustic unit 20 to the elastic buffer bracket 211. Alternatively, in the part where there is no elastic buffer bracket 211 between the outer shell of the acoustic unit 20 and the inner wall of the mounting groove 11, the damping buffer layer 212 can also be provided between the outer shell of the acoustic unit 20 and the inner wall of the mounting groove 11, so as to absorb and buffer the vibration from the outer shell of the acoustic unit 20 to the inner wall of the mounting groove 11 through the damping buffer layer 212. By setting a damping buffer layer 212, the vibration energy is further dissipated on the basis of the elastic buffer support 211, residual vibration is absorbed, vibration transmission to the mounting groove 11 is suppressed, and resonance of the mounting groove 11 is avoided. The damping buffer layer 212 forms a secondary vibration filter for the acoustic unit 20.

[0035] For example, the damping buffer layer 212 may be made of rubber, such as butyl rubber or nitrile rubber, or polyurethane, such as closed-cell polyurethane elastomer, or polymer damping material, such as polyacrylate or silicone rubber blend, or foam / porous material, such as polyurethane foam.

[0036] The damping buffer layer 212 can be a single layer or multiple layers. The thickness of the damping buffer layer 212 is not limited, as long as it meets the vibration reduction and buffering requirements.

[0037] In this embodiment of the application, the composite vibration isolation and buffer structure can also adopt a composite form with more levels, such as adding a third level of vibration filtering on the first-level and second-level vibration filtering structure to further absorb vibration. The structure of the third-level vibration filtering can be an elastic buffer support 211, a damping buffer layer 212 or other buffer devices.

[0038] like Figure 3As shown in the embodiment of this application, the acoustic unit 20 includes two sets of permanent magnets 21; the two sets of permanent magnets 21 form a mirror magnetic circuit structure. The acoustic unit 20 includes a magnetic circuit structure, which is used to realize the electro-mechanical conversion. By setting the magnetic circuit structure as a mirror magnetic circuit, the voice coil is subjected to uniform force, the linearity of the magnetic field is optimized, and a linear and symmetrical driving force can be generated, reducing the additional mechanical vibration caused by asymmetric vibration and electromagnetic distortion, making the vibration more stable and regular, and reducing vibration and distortion from the source; for example, the two permanent magnets 21 form a mirror magnetic circuit structure along the thickness direction of the acoustic unit 20.

[0039] In this embodiment, by adding a buffer device 21 and improving the magnetic circuit structure, the structure of the acoustic unit 20 can be optimized, giving it better mechanical filtering performance and preventing or attenuating vibration transmission to the support structure 10 or the touch unit 30. Based on the structural improvements, simultaneous compatibility testing is also possible, enabling the wearable device to be effectively tested. This achieves synergy between structural improvements and product testing, forming a complete quality closed loop.

[0040] In this embodiment, the touch unit 30 includes an information output port, which is used to connect to the touch sensor of the test equipment and output the touch information of the touch unit 30.

[0041] For example, the information output port is connected to the touch sensor via wireless or wired connection.

[0042] For example, touch information can be resistance value information or capacitance value information.

[0043] Based on the changes in the information value of the touch information, it is determined whether the vibration of the acoustic unit 20 affects the touch unit 30. If the information value changes, or the fluctuation characteristic parameter value of the touch information exceeds the set threshold range, it can be determined that the touch unit 30 is affected by vibration, that is, the current product has failed the test and is a defective product.

[0044] In this embodiment, the basic performance of the wearable device is guaranteed by the optimized design of the acoustic unit 20, so as to intercept some defective products caused by the variation in the compatibility test and realize the synergy between structural improvement and product testing.

[0045] Taking capacitance value as an example, the touch unit 30 includes a touch chip. The touch chip has an information output port for outputting the capacitance value. First, a reference value for the capacitance is obtained. For example, if the reference value is that the touch unit 20 has not been touched and the acoustic unit 20 is in a silent state (no sound), the reference value for the capacitance is obtained. Then, the acoustic unit 20 is activated, emitting sound and vibrating. At this time, the capacitance value, i.e., the actual value, is obtained in real time until the acoustic unit 20 reaches its maximum frequency. If the fluctuation characteristic parameter value still does not exceed the set threshold, the wearable device is deemed qualified; otherwise, if the fluctuation characteristic parameter value exceeds the set threshold, the wearable device is deemed unqualified.

[0046] Continue to refer to Figure 1 and Figure 2 As shown in the embodiment of this application, the wearable device is augmented reality (AR) glasses, which include a glasses frame 40; at least one temple of the glasses frame 40 includes a support structure 10, that is, at least one temple includes an acoustic unit 20 and a touch unit 30.

[0047] The acoustic unit 20 of the temple is equipped with a buffer device 21, and the structure of the acoustic unit 20 itself is optimized and designed as a mirror magnetic circuit. This structural improvement can effectively block or attenuate the impact of harmful vibrations from the acoustic unit 20 on the touch unit 30. Based on the structural optimization and improvement, performance tests are carried out in combination with the usage scenario, that is, the acoustic unit 20 is activated and the impact of the acoustic unit 20 on the touch unit 30 is tested to ensure the yield of the products leaving the factory.

[0048] When the user wears AR glasses and the acoustic unit 20 plays low-frequency and mid-frequency sounds, the vibration generated by the acoustic unit 20 will not affect (such as accidental triggering) the touch unit 30, thereby significantly improving the accuracy and reliability of operation.

[0049] like Figure 1 As shown, the touch unit 30 is placed inside the temple of the glasses. Its touch part is integrally formed with the structure of the temple. The touch part has the same appearance as the temple. Users can complete the operation by touching the touch part.

[0050] like Figure 4 As shown, this application embodiment provides a test fixture, including a test device 50, for testing the wearable device described above; the test device 50 includes a touch sensor 51, which is connected to the information output port of the wearable device.

[0051] The touch sensor 51 is connected to the information output port to receive touch information. The test equipment 50 determines whether the wearable device being tested is qualified based on the touch information.

[0052] The testing device 50 includes an excitation module 52, which is configured to control the acoustic unit 20 to emit sound at a set frequency. For example, the set frequency may include sounds covering low frequencies (e.g., 20Hz-200Hz, strong vibration sensation) and mid frequencies (e.g., 1kHz, common human voice). When the acoustic unit 20 is not emitting sound, the touch sensor 51 acquires a reference value for touch information; when the acoustic unit 20 emits sound at the set frequency, the touch sensor 51 acquires the actual value of the touch information.

[0053] Furthermore, the testing equipment 50 includes a comparison module 53; the comparison module 53 is configured to extract fluctuation characteristic parameter values ​​based on the baseline and actual values ​​of the touch information, and determine whether the current fluctuation characteristic parameter value exceeds a set threshold. Based on the comparison results, the wearable device under test is determined to be qualified; specifically, if the value is within the threshold range, it is considered qualified; otherwise, it is considered unqualified.

[0054] like Figure 5 As shown in the embodiments of this application, a testing method is provided, through which the testing method is used to test... Figures 1 to 3 The wearable device shown was tested using the following method: Step S10: Establish a baseline.

[0055] When the acoustic unit 20 is in a silent state, the touch information of the touch unit 30 is acquired and recorded as a reference value. The touch information is the capacitance value of the touch chip. When the acoustic unit 20 is in a silent state, the touch sensor is used to measure and record the capacitance reference value C0 of the touch chip.

[0056] Step S20: Dynamic stimulus.

[0057] The excitation module controls the acoustic unit 20 to emit sound. For example, the frequency range of the acoustic unit 20 can cover a certain range, such as a low-frequency range of 20Hz-200Hz or a mid-frequency range of 1kHz. The emission frequency can gradually change from low to high.

[0058] Step S30: Synchronous monitoring.

[0059] During the continuous sound emission from the acoustic unit 20, the touch sensor synchronously measures and records the capacitance value of the touch chip. That is, the obtained capacitance value is the actual value C. (t) Based on the reference value C0 and the actual value C (t) The instantaneous fluctuation value is calculated using the formula: ΔC (t) =|C (t) -C0|, and extracts fluctuation characteristic parameter values ​​based on instantaneous fluctuation values. For example, fluctuation characteristic parameters include the maximum fluctuation value ΔC_max, the average fluctuation value ΔC_avg, and the standard deviation σ; Step S40: Feature analysis and judgment.

[0060] Set a decision threshold, which can be a precise value or a range of values. If the obtained capacitance fluctuation characteristic parameter exceeds the threshold, the wearable device is judged as a defective product (FAIL); otherwise, the wearable device is a good product (PASS). When the fluctuation characteristic parameter includes the maximum value of the fluctuation ΔC_max, the average value of the fluctuation ΔC_avg, and the standard deviation σ, the corresponding thresholds are set respectively, that is, there are 3 thresholds, and they are compared separately. Alternatively, depending on the selection requirements, one or two of the three fluctuation characteristic parameters can be compared.

[0061] This application provides a wearable device and a testing fixture. The acoustic unit 20 of the wearable device is equipped with a buffer device 21 to form a mechanical filtering structure, achieving the purpose of blocking resonance. Simultaneously, touch information from the touch unit 30 can be output through the information output port, thereby enabling the wearable device to be tested. The yield rate of the wearable device can be tested even when the acoustic unit 20 is operating at high volume. This technical solution ensures the basic performance of the wearable device through structural optimization, while simultaneously intercepting defective products caused by variations. By combining structural improvement with product testing, a complete quality closed loop is formed to improve product quality.
