Implementation Method

[0017] It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention. To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art based on their ordinary knowledge should fall within the scope of protection of this application.

[0018] The loudspeaker testing method of the present invention is based on a loudspeaker testing device. Referring to Figure 1, Figure 1 is a structural schematic diagram of the first embodiment of the loudspeaker testing device of the present invention. The loudspeaker testing device includes a sealing module 100, an input channel 200, an output channel 300, a water supply module, an air supply module, a detection module, and a processing module 600; wherein: the input channel 200 and the output channel 300 are respectively connected to different sound-permeable holes 930 of the target loudspeaker 900; the sealing module 100 seals a plurality of sound-permeable holes 930 of the target loudspeaker 900, wherein the sound-permeable holes 930 connected by the input channel 200 and the output channel 300 and the... The sealing module 100 seals the sound-permeable holes 930, which include all the sound-permeable holes 930 of the target loudspeaker 900; the input channel 200 is also connected to the water outlet of the water supply module, the air outlet of the air supply module, and the first detection end of the detection module; the output channel 300 is also connected to the water inlet of the water supply module, the air inlet of the air supply module, and the second detection end of the detection module; the processing module 600 is connected to the water supply module, the air supply module, and the detection module.

[0019] The target speaker 900 is the speaker being tested; it should be noted that, depending on different testing needs, the target speaker 900 can be a standalone speaker module or a device with a speaker module installed, such as a smartwatch or other wearable device.

[0020] Referring to Figure 2, it can be understood that the sealing module 100, input channel 200, and output channel 300 cover all the sound-permeable holes 930 of the target loudspeaker 900, and the sound-permeable holes 930 covered by the sealing module 100 are sealed, that is, fluids such as water and air cannot enter or exit through these sound-permeable holes 930. A sealed cavity 920 is formed between the sound-permeable waterproof membrane 940 of the loudspeaker and the sound-permeable holes 930. Although the sound-permeable holes 930 connecting the input channel 200 and the output channel 300 are isolated from the external environment outside the input channel 200 and the output channel 300, fluids can enter and exit through the sound-permeable holes 930 through the input channel 200 and the output channel 300. That is, for the loudspeaker, fluids can only enter and exit through the sound-permeable holes 930 connecting the input channel 200 and the output channel 300. The specific sound-permeable holes 930 connecting the input channel 200 and the output channel 300 can be selected based on actual needs.

[0021] After the fluid transmission path of input channel 200, sound transmission hole 930 and output channel 300 is formed, the water or air output by the air supply module and the water supply module will enter the speaker cavity 920 through the input channel 200, and then be output from the speaker cavity 920 to the output channel 300; thus, the simulation of the speaker in water immersion scenario can be realized.

[0022] The detection module is used to detect the fluid state in the cavity 920. It is understood that, given that the fluid input from the air supply module and the water supply module is fixed, different states of the speaker will affect the fluid state of the cavity 920. For example, if there is water leakage, the pressure detected will be lower than if there is no water leakage. Therefore, the fluid state detected by the detection module can reflect the waterproof performance of the speaker, thereby realizing the detection of the speaker's waterproof performance.

[0023] The processing module 600 can be equipped with devices that have information processing capabilities based on actual needs. In order to facilitate the monitoring of the test process, a display 800 connected to the processing module 600 can also be set to display test parameters and results, as well as set test-related data.

[0024] In this embodiment, a sealed cavity is constructed by setting a sealing module 100, an input channel 200, and an output channel 300 to connect the speaker, the water supply module, the air supply module, and the detection module. At the same time, the water supply module and the air supply module can change the state of the fluid in the cavity 920, thereby adjusting the fluid environment in which the speaker is located. Meanwhile, the detection module detects the state of the fluid in the cavity 920, thereby enabling the detection of the speaker's waterproof performance.

[0025] Further, referring to Figures 1 and 2, the sealing module 100 includes a lower sealing block 120, an upper sealing block 110, a sealing pressure block 111, and a motor M; wherein: the lower sealing block 120 is matched with the target speaker 900, and when the target speaker 900 is fixed to the lower sealing block 120, the sound-transmitting hole 930 side of the target speaker 900 faces the upper sealing block 110; the upper sealing block 110 is connected to the motor M, and the sealing pressure block 111, the input channel 200, and the output channel 300 are fixedly connected to the upper sealing block 110, wherein the input channel 200 communicates with the first sound-transmitting hole of the target speaker 900, the output channel 300 communicates with the tail sound-transmitting hole of the target speaker 900, and the sealing pressure block 111 seals the middle sound-transmitting hole of the target speaker 900; the motor M is used to control the upper sealing block 110 to move in a direction relative to the target speaker 900.

[0026] The lower sealing block 120 is used to fix the target speaker 900; in order to achieve matching with various target speakers 900, a fixing pin can also be provided on the side of the lower sealing block 120 away from the upper sealing block 110; specifically, the lower sealing block 120 can be provided with a sealing block positioning fixing pin 121 and a speaker positioning fixing pin 122; the sealing block positioning fixing pin 121 is provided on the outside of the lower sealing block 120, and the speaker positioning fixing pin 122 is provided on the inside of the lower sealing block 120. The sealing block positioning fixing pin 121 is used to adjust the position of the lower sealing block 120 itself, while the speaker positioning fixing pin 122 is used to adjust the depth of the target speaker 900 in the lower sealing block 120.

[0027] The upper sealing block 110 serves as a support for the sealing pressure block 111, the input channel 200, and the output channel 300. By controlling the movement of the upper sealing block 110, the movement of the sealing pressure block 111, the input channel 200, and the output channel 300 is controlled, so that the sealing pressure block 111 seals the vent hole, and the input channel 200 and the output channel 300 communicate with the vent hole (e.g., the sound transmission hole 930 of a watch). The upper sealing block 110 is connected to the motor M, and the motor M controls the lifting and lowering of the upper sealing block 110.

[0028] In this embodiment, in order to form a passage through the complete cavity 920, the input channel 200 and the output channel 300 are respectively connected to the sound-permeable holes 930 on the side. For example, if the loudspeaker contains 5 sound-permeable holes 930 arranged in sequence, based on the arrangement order as the first sound-permeable hole, the second sound-permeable hole, the third sound-permeable hole, the fourth sound-permeable hole, and the fifth sound-permeable hole, the input channel 200 can be connected to the first sound-permeable hole (first sound-permeable hole), and the output channel 300 can be connected to the fifth sound-permeable hole (tail sound-permeable hole), or the input channel 200 can be connected to the fifth sound-permeable hole (tail sound-permeable hole), and the output channel 300 can be connected to the first sound-permeable hole (first sound-permeable hole).

[0029] Further, the water supply module includes a water tank WB, a water pump WP, and a first proportional regulating valve PF1; wherein: the outlet of the water tank WB is connected to the input channel 200 in sequence through the water pump WP and the first proportional regulating valve PF1, and the inlet of the water tank WB is connected to the output channel 300; the control terminal of the water pump WP is connected to the processing module 600, and the control terminal of the first proportional regulating valve PF1 is connected to the processing module 600.

[0030] Water tank WB is used for water storage; water pump WP is used for drawing water from water tank WB for output; first proportional regulating valve PF1 is used to control the flow rate of output water; when water needs to be output to input channel 200, water pump WP draws water from water tank WB and outputs it to first proportional regulating valve PF1, and first proportional regulating valve PF1 outputs water to input channel 200 based on the set working parameters; the on / off state and specific working parameters of water pump WP and first proportional regulating valve PF1 are controlled by processing module 600 according to test process and status.

[0031] When the water in the cavity 920 needs to be drained, the water flows back to the water tank WB through the output channel 300.

[0032] Further, the gas supply module includes a gas pressurizing pump AP, a second proportional regulating valve PF2, an exhaust device, and a vacuum pump PZ; wherein: the gas pressurizing pump AP is connected to the input channel 200 through the second proportional regulating valve PF2; the exhaust device and the vacuum pump PZ are respectively connected to the output channel 300; the control terminal of the gas pressurizing pump AP is connected to the processing module 600, the control terminal of the second proportional regulating valve PF2 is connected to the processing module 600, and the control terminal of the vacuum pump PZ is connected to the processing module 600.

[0033] The gas pressurization pump AP is used to extract air; the second proportional regulating valve PF2 is used to control the air flow rate; the exhaust device is used to discharge the gas in the channel; and the vacuum pump PZ is used to extract the gas in the channel.

[0034] When it is necessary to increase the air pressure of the input channel 200, the gas pressurization pump AP draws in external air and outputs it to the second proportional regulating valve PF2; the second proportional regulating valve PF2 outputs air to the input channel 200 based on the set operating parameters; when the air in the channel needs to be discharged, the vacuum pump PZ runs, and the air in the channel is discharged through the exhaust device.

[0035] The gas pressurization pump AP, the second proportional regulating valve PF2, the exhaust device and the vacuum pump PZ are switched on and off, and their specific operating parameters are controlled by the processing module 600 according to the test process and status.

[0036] Further, the detection module includes a first pressure sensor P1 and a second pressure sensor P2; wherein: the detection end of the first pressure sensor P1 is connected to the input channel 200, and the output end of the first pressure sensor P1 is connected to the processing module 600; the detection end of the second pressure sensor P2 is connected to the output channel 300, and the output end of the first pressure sensor P1 is connected to the processing module 600.

[0037] The first pressure sensor P1 is used to detect the pressure in the input channel 200 and send the detected pressure value to the processing module 600; the second pressure sensor P2 is used to detect the pressure in the output channel 300 and send the detected pressure value to the processing module 600.

[0038] Further, the detection module includes a first optical sensor L1 and a second optical sensor L2; wherein, the input channel 200 and the output channel 300 are transparent pipes; the first optical sensor L1 is disposed on the input channel 200, and the second optical sensor L2 is disposed on the output channel 300; the output end of the first optical sensor L1 is connected to the processing module 600, and the output end of the second optical sensor L2 is connected to the processing module 600.

[0039] It is understood that air and water have different refractive indices for light. Therefore, when the input channel 200 or the output channel 300 is filled with air or water, different optical conditions will be presented. Therefore, in order to further detect the fluid state in the input channel 200 and the output channel 300, in this embodiment, the input channel 200 and the output channel 300 are set as transparent pipes, and a light sensor is set. Thus, by detecting the refracted light by the light sensor, the fluid state in the input channel 200 and the output channel 300 can be determined; the light sensor sends the detected light signal to the processing module 600.

[0040] Further, the air supply module includes an exhaust device and a vacuum pump PZ; the input channel 200 is provided with a first valve F1 and a second valve F2; the output channel 300 is provided with a third valve F3, a fourth valve F4 and a fifth valve F5; wherein: the input channel 200 is connected to the air supply module through the first valve F1, and the input channel 200 is connected to the water supply module through the second valve F2; the output channel 300 is connected to the exhaust device of the air supply module through the third valve F3, the output channel 300 is connected to the water supply module through the fourth valve F4, and the output channel 300 is connected to the vacuum pump PZ of the air supply module through the fifth valve F5; the control terminals of the first valve F1, the second valve F2, the third valve F3, the fourth valve F4 and the fifth valve F5 are respectively connected to the processing module 600.

[0041] It is understood that the requirements for the fluid state in the cavity 920 are different in different test procedures. Therefore, in order to meet the different test procedures, in this embodiment, the first valve F1, the second valve F2, the third valve F3, the fourth valve F4, and the fifth valve F5 are set to control the opening and closing of the channel inlet and outlet.

[0042] The first valve F1 controls whether the air supply module is connected to the input channel 200, the second valve F2 controls whether the water supply module is connected to the input channel 200, the third valve F3 controls whether the exhaust device is connected to the output channel 300, the fourth valve F4 controls whether the water supply module is connected to the input channel 200, and the fifth valve F5 controls whether the vacuum pump PZ is connected to the output channel 300.

[0043] By adjusting the above valves, different test procedures can be achieved; for example, if the first valve F1 and the third valve F3 are open, and the second valve F2, the fourth valve F4, and the fifth valve F5 are closed, the connected passages are, in sequence, the air supply module, the input channel 200, the cavity 920, the output channel 300, and the exhaust device; at this time, the moisture and impurities in the channel and the cavity 920 can be discharged by blowing air through the air supply module; if the first valve F1 is open, and the second valve F2, the third valve F3, the fourth valve F4, and the fifth valve F5 are closed, At this point, the connecting pathways are sequentially: air supply module, input channel 200, cavity 920, and output channel 300. Air pressure within the channels and cavity 920 can be increased by blowing air through the air supply module. If the second valve F2 and the fourth valve F4 are open, and the first valve F1, the third valve F3, and the fifth valve F5 are closed, the connecting pathways are sequentially: water supply module, input channel 200, cavity 920, output channel 300, and water supply module. Water from the water supply module flows through cavity 920 and then back to the water supply module. For example, if the first valve F1... When the fourth valve F4 is open, and the second valve F2, third valve F3, and fifth valve F5 are closed, the connected pathways are sequentially: air supply module, input channel 200, cavity 920, output channel 300, and water supply module. At this time, air can be blown through the air supply module to remove moisture from the channels and cavity 920. If the fifth valve F5 is open, and the first valve F1, second valve F2, third valve F3, and fourth valve F4 are closed, the connected pathways are sequentially: input channel 200, cavity 920, output channel 300, and vacuum pump PZ. At this time,... The vacuum pump PZ is used to remove residual moisture from the channel and cavity 920. It can be understood that the vacuum pump PZ reduces the air pressure inside the cavity 920, thus accelerating the conversion of water molecules into gas and completing the drying process more quickly. If the fourth valve F4 is open and the first valve F1, the second valve F2, the third valve F3, and the fifth valve F5 are closed, the connected pathways are, in sequence, the input channel 200, the cavity 920, the output channel 300, and the water supply module. At this time, the sound-transmitting hole 930 is connected to the atmosphere, and the air pressure inside the cavity 920 returns to atmospheric pressure.

[0044] It is understood that the control of the first valve F1 to the fifth valve F5 can be set based on actual test needs. The above is only an explanation of some feasible scenarios.

[0045] Further, the speaker waterproof testing device also includes a button testing module 700; the button testing module 700 is disposed opposite to the physical button 910 of the target speaker 900, and the button testing module 700 is connected to the processing module 600; the button testing module 700 is used to output press feedback data to the processing module 600 when it contacts the physical button 910 of the target speaker 900.

[0046] After the speaker is assembled in the smartwatch, the physical button 910 of the smartwatch usually needs to be tested. In this embodiment, by setting up a button test module 700, the physical button 910 can be tested at the same time as the speaker, so that no additional test fixture is needed and the testing efficiency is improved.

[0047] The button test module 700 obtains press feedback data by contacting the physical button 910 of the target speaker 900, and sends the press feedback data to the processing module 600. The processing module 600 determines whether the assembly of the physical button 910 meets the requirements based on the press feedback data.

[0048] Further, the button testing module 700 includes a first distance pressure sensor D1, a second distance pressure sensor D2, a first probe 711, and a second probe 712; wherein: the first probe 711 and the second probe 712 are fixedly connected to the upper sealing block 110 of the sealing module 100; the first probe 711 is connected to the first distance pressure sensor D1, and the output end of the first distance pressure sensor D1 is connected to the processing module 600; the second probe 712 is connected to the second distance pressure sensor D2, and the output end of the second distance pressure sensor D2 is connected to the processing module 600.

[0049] The first probe 711 and the second probe 712 are used to contact the physical button 910; the first distance pressure sensor D1 is used to detect the pressure of the first probe 711, and the second distance pressure sensor D2 is used to detect the pressure of the second probe 712.

[0050] The testing of physical buttons 910 mainly includes button assembly levelness and assembly depth.

[0051] When setting the first probe 711 and the second probe 712, the positions of the first probe 711 and the second probe 712 can be set based on the specific structure of the physical button 910; for example, the first probe 711 and the second probe 712 are symmetrically set based on the central axis of the qualified physical button 910. Generally, the physical button 910 adopts a symmetrical design. Therefore, when the first probe 711 and the second probe 712 are in contact with the qualified physical button 910, the pressure values ​​reflected on the first distance pressure sensor D1 and the second distance pressure sensor D2 should be the same.

[0052] When the physical button 910 has an assembly level problem, there will be a significant difference in the pressure values ​​on the first distance pressure sensor D1 and the second distance pressure sensor D2; when the physical button 910 has an assembly depth problem, there will be problems with the pressure values ​​on the first distance pressure sensor D1 and the second distance pressure sensor D2 being too large or too small; based on this, the assembly test of the physical button 910 can be realized.

[0053] The present invention provides a loudspeaker testing method, applied to the above-mentioned loudspeaker testing device. Referring to FIG3, FIG3 is a schematic flowchart of the first embodiment of the loudspeaker testing method of the present invention, the method includes the following steps:

[0054] Step S10: Control the input channel and output channel to connect to different sound holes of the target loudspeaker, and seal the other sound holes of the target loudspeaker through the sealing module to form a cavity at the sound holes of the target loudspeaker; the sealing module, input channel, and output channel cover all the sound holes of the target loudspeaker, and the sound holes covered by the sealing module are sealed, that is, fluids such as water and air cannot enter or exit through these sound holes; although the sound holes connected to the input channel and output channel are isolated from the external environment outside the input channel and output channel, fluids can enter and exit through the sound holes of the input channel and output channel; that is, for the loudspeaker, fluids can only enter and exit through the sound holes connected to the input channel and output channel; the specific sound holes connected to the input channel and output channel can be selected based on actual needs.

[0055] After the fluid transmission path of the input channel, sound transmission hole and output channel is formed, the water or air output by the air supply module and the water supply module will enter the speaker cavity through the input channel and then be output from the speaker cavity to the output channel.

[0056] Step S20: Adjust the fluids output to the input channel by the air supply module and the water supply module to adjust the fluid state within the cavity; the fluids include liquids and gases, and water and air are used as examples in this application. It is understood that the water supply module outputs water to the cavity through the input channel, and the air supply module outputs air to the cavity through the input channel; based on the fluid retention within the cavity and the inputs from the water supply module and the air supply module, the fluid state within the cavity will change, and different performance tests have different requirements for the fluid state within the cavity. Therefore, this embodiment can match different test needs by adjusting the fluid state within the cavity.

[0057] Step S30: Obtain the fluid state parameters in the cavity detected by the detection module, and perform performance testing on the target loudspeaker based on the fluid state parameters.

[0058] The fluid state parameters reflect the fluid state inside the cavity. It is understood that when the fluid input by the air supply module and the water supply module is determined, different states of the speaker will affect the fluid state of the cavity. For example, when there is water leakage, the pressure detected is lower than when there is no water leakage. Therefore, the fluid state detected by the detection module can reflect the waterproof performance of the speaker, thereby realizing the detection of the waterproof performance of the speaker.

[0059] In this embodiment, a sealed cavity is constructed by setting a sealing module, an input channel, and an output channel to connect the speaker, the water supply module, the air supply module, and the detection module. At the same time, the water supply module and the air supply module can change the state of the fluid in the sealed cavity, thereby adjusting the fluid environment in which the speaker is located. Meanwhile, the detection module detects the state of the fluid in the sealed cavity, thereby enabling the detection of the speaker's waterproof performance.

[0060] Further, in the second embodiment of the loudspeaker testing method of the present invention based on the first embodiment of the present invention, step S20 includes the following steps:

[0061] Step S21: Gas is output from the gas supply module to the input channel to adjust the gas pressure in the cavity to a preset gas pressure.

[0062] Step S22: Water is output to the input channel through the water supply module so that the cavity is filled with water.

[0063] Step S23: Pressurize the cavity through the air supply module so that the pressure inside the cavity is sequentially adjusted to multiple different preset water pressures.

[0064] In this embodiment, different fluid environments are constructed within the cavity by way of example. Specifically: gas is output to the input channel through the gas supply module so that the cavity contains only air, and the air pressure is a preset pressure. The specific value of the preset pressure can be set based on actual needs. It is understood that in order to adjust the air pressure in the cavity to be different from the atmospheric pressure, the cavity needs to be isolated from the atmospheric environment. Taking the speaker testing device shown in Figure 1 as an example, the first valve can be opened, and the second, third, fourth, and fifth valves can be closed. At this time, the gas pressure in the channel and cavity can be increased by blowing air through the gas supply module. Water is output to the input channel through the water supply module to expel the air in the cavity and make the cavity full of water. In specific implementation, the first valve can be opened, and the second, third, fourth, and fifth valves can be closed. The second and fourth valves are open, while the first, third, and fifth valves are closed. At this time, the connection path is sequentially: water supply module, input channel, cavity, output channel, and water supply module. Water in the water supply module flows through the cavity and then back to the water supply module. Once the cavity is full of water, the second and fourth valves are closed. In practical applications, to ensure that the cavity is full of water, the pressure detection value of the second pressure sensor can be obtained to detect the pressure in the cavity. When the pressure matches that of a full water condition, the cavity is considered to be full of water. Furthermore, since water and air have different refractive indices for light, the input and output channels can be set as transparent pipes, and optical sensors can be installed on them to detect the fluid in the channels to determine whether the cavity is full of water.

[0065] When the cavity is filled with water, the air supply module pressurizes the cavity to increase the pressure inside the cavity; in specific implementation, the first valve can be opened and the second, third, fourth and fifth valves can be closed; at this time, the pressure inside the channel and cavity can be increased by blowing air through the air supply module; it is understood that when pressurizing the cavity, based on the test requirements, the pressure inside the cavity can be adjusted to different preset water pressures in sequence, such as selecting multiple pressure points between 0.1 and 1 bar, and performing relevant tests based on each pressure point.

[0066] In addition to the above-mentioned fluid states, in actual testing, the cavity can be adjusted to different fluid states based on testing needs.

[0067] Further, the air supply module includes a first proportional regulating valve connected to the input channel, the detection module includes a first pressure sensor connected to the input channel and a second pressure sensor connected to the output channel, and step S30 includes the following steps:

[0068] Step S31: When the air pressure in the cavity is the preset air pressure, obtain the pressure parameter of the first proportional regulating valve, and obtain the pressure detection values ​​of the first pressure sensor and the second pressure sensor.

[0069] Step S32: Detect the sound transmission and air permeability of the loudspeaker based on the pressure parameters and the pressure detection value.

[0070] The waterproofing of the loudspeaker is achieved by setting an acoustically permeable waterproof membrane; while the acoustically permeable waterproof membrane achieves the waterproofing function, it is also necessary not to affect the sound output function of the loudspeaker. Therefore, it is necessary to test the sound transmission and air permeability.

[0071] There are gas fluid state equations and mass continuity equations: [Number 1]

[0072] Where P is the gas pressure inside the cavity; R is the gas constant; min and out are the mass flow rates into and out of the cavity, respectively; V is the equivalent volume of the cavity; υ is the outflow velocity; T is the gas temperature; and Kin, Out, and K1 are coefficients.

[0073] In the absence of gas leakage, we have: [Number 2]

[0074] At this point, the specific values ​​of the coefficients can be determined by methods such as the experimental method and the least squares method.

[0075] The gas pressure inside the cavity can be controlled by controlling the pressure parameters of the proportional regulating valve and the gas pressurizing pump. The pressure inside the cavity is detected by the first pressure sensor and the second pressure sensor to obtain the pressure detection value. It can be understood that the first pressure sensor detects the pressure at the inlet of the cavity and the second pressure sensor detects the pressure at the outlet of the cavity. Therefore, gas leakage in the cavity will be reflected in the pressure difference between the first pressure sensor and the second pressure sensor. Therefore, after obtaining the pressure detection value, the sound transmission and air permeability can be determined by the difference between the two. At the same time, the gas leakage amount can be obtained by substituting the pressure detection value into the gas fluid state equation and the mass continuity equation.

[0076] Furthermore, when conducting large-scale, continuous target loudspeaker tests, water will be injected into the channel during the test process. Therefore, when testing new target loudspeakers, there may be residual moisture. Therefore, before setting the air pressure in the cavity to the preset air pressure, the first valve and the third valve can be opened first, and the gas pressurization pump can be controlled to blow air to remove residual moisture and avoid affecting the test results.

[0077] Further, step S30 includes the following steps:

[0078] Step S33: When the pressure in the cavity is the preset water pressure, obtain the pressure parameter of the first proportional regulating valve, and obtain the pressure detection values ​​of the first pressure sensor and the second pressure sensor.

[0079] Step S34: Determine the test level corresponding to the pressure parameter, and determine the waterproof performance of the speaker under the test level based on the pressure detection value.

[0080] Step S35: Determine the waterproof rating of the speaker according to the waterproof performance corresponding to each preset water pressure.

[0081] It is understandable that different waterproof ratings require different pressure resistance levels. For example, the higher the waterproof rating, the higher the pressure resistance of the speaker is required. Therefore, during testing, it is necessary to construct different water pressure environments to meet the testing requirements of different waterproof ratings.

[0082] The pressure parameter is used to indicate the output of the first proportional regulating valve; different pressure parameters result in different pressures in the cavity, so the test level can be determined by the pressure parameter; then the waterproof performance of the speaker is tested for different test levels to determine the waterproof level of the speaker; the pressure parameter can be set according to actual needs, such as selecting the required pressure in the range of 0.01~1 Bar as the pressure value corresponding to the test level.

[0083] Further, step S35 includes the following steps:

[0084] Step S351, obtain the initial pressure value, wherein the initial pressure value is the detection value of the first pressure sensor and the second pressure sensor when the cavity is filled with water and the air supply module does not pressurize the cavity;

[0085] Step S352: Calculate the change between the initial pressure value and the pressure detection value;

[0086] Step S353: Obtain the change threshold corresponding to the test level;

[0087] Step S354: Determine the waterproof performance of the speaker at the test level based on the change value and the change threshold.

[0088] After the cavity is filled with water, the water pressure in the cavity gradually increases as the air supply module pressurizes. When the water pressure reaches a certain value, the speaker sound-permeable waterproof module and the edge sealing structure deform, resulting in water leakage. In the event of water leakage, the pressure detection values ​​of the first pressure sensor and the second pressure sensor change. Based on this, the waterproof performance can be detected.

[0089] According to the laws of conservation of mass and momentum in fluid mechanics, let Ω(t) be the spatial region occupied by a point Q of the cavity, the speaker's sound-permeable waterproof membrane, and the edge sealing structure at time t. Then its mass M(t) is: [Chapter 3]

[0090] When water leaks from the cavity into the watch, it satisfies the integral continuity equation: [Chapter 4]

[0091] Where v1 is the flow velocity of water in the cavity, s1 is the equivalent effective area, v2 is the flow velocity of water through the sound-permeable membrane or waterproof structure, s2 is the equivalent effective area, and ρ is the density of water; then the pressure F(t) at the water leakage point Ω(t) is: [5]

[0092] Where g is the gravitational acceleration, h is the height of the leak point in the cavity from the liquid surface in the cavity, and P1 is the pressure detection value of the first pressure sensor.

[0093] The surface integral of Ω(t) yields: [Calligraphy 6]

[0094] Therefore, the leakage amount can be converted into the relationship between pressure and pressure difference, which yields: [Number 7]

[0095] Where P2 is the pressure detection value of the second pressure sensor; K2, K3, and K4 are coefficients that can be obtained by the least squares method.

[0096] As can be seen from the above, when the cavity is sealed and there is no leakage, the water is incompressible and the water does not flow, which is equivalent to v1 / v2=0. When there is leakage, v1 and v2 will change, causing pressure changes. The leakage situation can be determined by comparing the changes in the pressure detection values ​​of the first pressure sensor and the second pressure sensor.

[0097] When there is no water leakage in the cavity, the pressure monitoring values ​​of the first and second pressure sensors are measured multiple times under different waterproof levels, i.e., different pressures, as reference values ​​to calculate the correlation coefficient. When the waterproof performance of the cavity does not meet the design specifications, the flow of water in the cavity will cause a change in the pressure detection value. The change value is the difference between the pressure detection values ​​before and after leakage. Different leakage rates are determined according to the magnitude of the change value. The initial pressure value is the pressure value before pressurization. After pressurizing the cavity, the pressure detection values ​​of the second pressure sensor and the second pressure sensor are monitored. When the pressure detection value changes, the change value is determined based on the pressure detection value and the initial pressure value. It can be understood that for each test level, it is determined whether the change value meets the waterproof requirements. That is, if the change value is less than the change threshold, it is considered to meet the waterproof requirements. If the change value is greater than or equal to the change threshold, it is considered not to meet the waterproof requirements. If the waterproof requirements are met, it is considered that the speaker at least meets the current test level. After all test levels are completed, the highest test level that is met can be determined as the waterproof level of the target speaker. This realizes the digital quantification of the waterproof level, making the waterproof level more intuitive.

[0098] In other embodiments, a specific target waterproof level can be set, and the change value is monitored under the target waterproof level. If the change value is less than the change threshold corresponding to the target waterproof level, the target speaker has reached the target waterproof level.

[0099] Further, in the third embodiment of the loudspeaker testing method of the present invention based on the first embodiment of the present invention, the step S30 is followed by the following step:

[0100] Step S40: Air is output to the input channel through the air supply module to drain the water in the cavity;

[0101] Step S50: Control the vacuum pump to run for a preset time.

[0102] After the test is completed, in order to avoid the moisture from affecting the target speaker, the target speaker needs to be dried. It is understandable that a vacuum pump can reduce the air pressure inside the cavity, accelerate the water molecules to turn into gas, and thus quickly dry the speaker.

[0103] Changes in pressure on both sides of the sound-permeable and waterproof membrane of the watch speaker can cause deformation of the membrane. Once the deformation reaches a certain amount, it cannot be reversed and will affect the sound quality of the watch speaker. Therefore, before the vacuum pump is run, a large amount of moisture can be expelled by blowing air through the air supply module. Then, the vacuum pump can be controlled to run for a preset time to achieve complete drying of the speaker. At the same time, the vacuum pump should not be run for too long, which would affect the sound quality of the speaker. Furthermore, the optimal vacuum pressure can be determined in advance so that the vacuum pump can run based on the vacuum pressure, which would further prevent the sound quality of the speaker from being affected.

[0104] Furthermore, after drying is completed, the air pressure inside the cavity is different from the atmospheric pressure. Therefore, before removing the target speaker, the fourth valve can be opened to connect the cavity with the external environment so that the air pressure inside the cavity is the same as the atmospheric pressure. Then, the input channel, output channel and sealing module can be disconnected to remove the target speaker.

[0105] Further, in the fourth embodiment of the loudspeaker testing method of the present invention based on the first embodiment of the present invention, the step S10 is followed by the following step:

[0106] Step S60: Obtain the press feedback data of the button test module.

[0107] Step S70: Determine the installation status of the physical button of the target speaker based on the press feedback data.

[0108] After the speaker is assembled in the smartwatch, it is usually necessary to test the physical buttons of the smartwatch. In this embodiment, by setting up a button test module, the physical buttons can be tested at the same time as the speaker, so that no additional test fixtures are needed, thus improving the testing efficiency.

[0109] The button testing module obtains press feedback data by contacting the physical button of the target speaker, and sends the press feedback data to the processing module. The processing module determines whether the physical button assembly meets the requirements based on the press feedback data.

[0110] The overall flow of the loudspeaker testing method of the present invention will be described below with reference to Figure 3:

[0111] 1. The target speaker is placed on the watch positioning pin inside the lower sealing block.

[0112] 2. The operator sets parameters such as the pressure between the upper and lower sealing blocks, the gas pressure between the sound-permeable hole and the sound-permeable waterproof membrane, the water pressure, the blowing time, the vacuum pressure, the sound transmission and air permeability of the target loudspeaker, the leakage of the waterproof seal, and the negative pressure drying on the display.

[0113] 3. The processing module controls the motor to move the upper sealing block downwards and seal it with the lower sealing block at a set pressure. The pressure sensor on the sealing pressure block measures the sealing pressure in real time and displays it on the display. The sealing pressure block blocks all sound-transmitting holes except for the first and last sound-transmitting holes. The target speaker and the sound-transmitting hole form a cavity with left-in and right-out based on the input and output channels. The input and output channels are connected to the gas pressurization pump, water pump, first pressure sensor, and second pressure sensor to provide the required gas and water pressure for the test system. The first and second probes contact the watch button. The first and second distance pressure sensors synchronously measure the pressure and distance of the first and second probes, thereby measuring the horizontality and depth of the physical button installation.

[0114] 4. The processing module controls the first and third valves to open, and the second, fourth and fifth valves to close. The gas pressurization pump works to blow air into the sealed cavity to remove moisture and internal debris from the cavity.

[0115] 5. The processing module controls the second, third, fourth, and fifth valves to close, the first valve to open, the gas pressurization pump to work, the cavity to withstand the gas pressure set by the pressurization pump, maintain the pressure for a period of time, the first pressure sensor to measure the pressure in the cavity in real time, and calculate the sound transmission and air permeability of the target loudspeaker according to the proportional adjustment of the measured values ​​of the first valve, the first pressure sensor, and the second pressure sensor.

[0116] 6. The processing module controls the first, third, and fifth valves to close, the second and fourth valves to open, the water pump working chamber to fill with water, and the first and second optical sensors to measure whether the chamber is full of water.

[0117] 7. The processing module controls the second, third, fourth, and fifth valves to close and the first valve to open. The gas pressurization pump works, and the target speaker in the cavity is subjected to the superimposed air pressure and water pressure. After maintaining the pressure for a period of time, the first and second pressure sensors measure the pressure in the cavity in real time, and calculate the waterproof performance leakage of the target speaker according to the proportional adjustment of the measured values ​​of the first valve, the first pressure sensor, and the second pressure sensor. The waterproof rating is digitally quantified and measured.

[0118] 8. The processing module controls the second, third, and fifth valves to close, and opens the first valve. The fourth valve and the gas pressurization pump operate for a set time, and most of the water in the cavity is blown away.

[0119] 9. The processing module controls the first, second, third, and fourth valves to close, the fifth valve to open, and the vacuum pump to operate for a set time. The residual moisture in the cavity will be reduced due to the decrease in cavity air pressure, which will accelerate the water molecules to turn into gas, and the target speaker will be dried.

[0120] 10. The processing module controls the first valve, second valve, fourth valve, and fifth valve to close and open the fourth valve, so that the sound transmission hole of the target speaker is connected to the outside atmosphere. Then, the lifting motor is controlled to rise to the limit position, and the target speaker completes the measurement of sound transmission and air permeability, waterproof performance, speaker drying, watch button assembly level, and watch button assembly depth.

[0121] 11. The operator takes out the tested watch based on the test results displayed on the screen and places it in the corresponding quality area.
