As diving becomes increasingly popular, the market for dive watches is expanding, and the demand for underwater sound pickup is growing. However, most existing wearable dive watches do not support audio functionality and cannot be used underwater to pick up sounds. Therefore, there is an urgent need for an electronic device capable of underwater sound pickup. Summary of the Invention

This allows the electronic device to collect sound in different working environments, thereby ensuring that the electronic device can collect ambient sound effectively in different environments and improving the user experience.

[0006] In one alternative design, the first environment includes a liquid environment and the second environment includes an air environment.

For example, the electronic device may collect sound through the underwater acoustic transducer or microphone in response to a user-triggered sound pickup operation. For instance, when the electronic device is a mobile phone, the sound pickup operation may be the user clicking the record button of a recording application on the phone, or other operations that trigger recording. As another example, when the electronic device is a recording device, the sound pickup operation may be the operation of activating the electronic device. For example, the electronic device may collect sound through the underwater acoustic transducer or microphone in response to a user-triggered activation operation.

[0083] For example, such as Figure 2 As shown, electronic devices can use microphones or underwater acoustic transducers to collect sound from the surrounding environment in the following ways: S201: Electronic equipment testing: The working environment of the electronic equipment.

[0084] In some embodiments, before the electronic device performs sound acquisition, it needs to determine its operating environment so that the device can select the appropriate device from the microphone and underwater acoustic transducer for recording based on the current operating environment. This ensures the sound pickup effect of the electronic device in different environments. The operating environment of the electronic device includes, but is not limited to: liquid environment, air environment, shallow water environment, and deep water environment. For example, an air environment can be any environment other than a liquid environment. A deep water environment is a liquid environment with a depth greater than or equal to a first depth threshold. A shallow water environment is a liquid environment with a depth less than a second depth threshold; the liquid environment can be an underwater environment such as a swimming pool, ocean, river, lake, or basin, or other non-aquatic liquid environments such as an oil tank. The first depth threshold and the second depth threshold can be the same or different.

[0085] As an example, electronic devices can determine their operating environment not only through water immersion detection, but also through both water immersion detection and depth detection. For instance, water immersion detection can determine whether the electronic device's operating environment is air or a liquid environment. Depth detection can determine whether the electronic device's operating environment is a liquid environment, or a deep or shallow water environment within a liquid environment. The following sections will explain these two methods of detecting the operating environment.

[0086] Method 1: Water immersion detection: In some embodiments, the electronic device may include a water ingress detection sensor, thereby enabling the electronic device to detect its operating environment. The water ingress detection sensor may be a barometer, a capacitive water ingress detection sensor, a resistive water ingress detection sensor, or other general-purpose sensors capable of water ingress detection; no limitation is made herein.

[0087] When an electronic device determines that it needs to collect sound from its surroundings, it uses a water immersion sensor to detect whether the device is operating in a liquid or air environment. For example, the electronic device can perform water immersion detection in the following ways.

[0088] Electronic devices can acquire environmental parameters collected by water ingress detection sensors. For example, when the water ingress detection sensor is a resistive type, the environmental parameter can be a resistance value, a voltage value, or other parameters, which are not limited here. As another example, when the water ingress detection sensor is a capacitive type, the environmental parameter can be a capacitance value, voltage, current value, or charge / discharge time.

[0089] The processor of an electronic device can determine whether the operating environment of the electronic device is a liquid environment or an air environment based on environmental parameters. For example, when the environmental parameters are greater than or equal to a set threshold, the electronic device can determine that the operating environment is a liquid environment. When the environmental parameters are less than the set threshold, the electronic device can determine that the operating environment is an air environment. In this embodiment, the set threshold can be a water immersion threshold for determining whether it is a liquid environment, or an air threshold for determining whether it is an air environment. For example, when the environmental parameters are greater than or equal to the water immersion threshold, the electronic device can determine that the operating environment is a liquid environment; when the environmental parameters are less than the water immersion threshold, the electronic device can determine that the operating environment is an air environment. As another example, the electronic device can also determine that the operating environment is an air environment when the environmental parameters are less than the air threshold; and when the environmental parameters are greater than or equal to the air threshold, the electronic device can determine that the operating environment is a liquid environment. Furthermore, the electronic device can also perform water immersion detection in other ways to determine whether the operating environment of the electronic device is an air environment or a liquid environment, which is not limited here.

[0090] Method 2: Water immersion detection and depth detection: In some embodiments, the electronic device can detect its operating environment using a water immersion detection sensor and a depth sensor. For example, such as... Figure 3 As shown, the electronic device may include a water ingress detection sensor and a depth sensor.

[0091] As an example, when it is determined that sound acquisition of the surrounding environment is required, an electronic device can perform water immersion detection using a water immersion sensor and depth detection using a depth sensor to determine the operating environment of the electronic device. For example, the electronic device can perform water immersion detection and depth detection in the following ways.

[0092] Electronic devices can acquire environmental parameters collected by water immersion detection sensors and perform water immersion detection based on these parameters. For example, such as... Figure 3 As shown, the processor of the electronic device can determine whether the operating environment of the electronic device is a liquid environment or an air environment based on environmental parameters. The method for water immersion detection in Method 2 is the same as that in Method 1, and will not be described again here.

[0093] The electronic device can also acquire depth values ​​collected by a depth sensor. When the depth value is greater than or equal to a first depth threshold and the working environment of the electronic device is a liquid environment, the electronic device can determine that its working environment is a deep water environment. When the depth value is less than a second depth threshold and the working environment of the electronic device is a liquid environment, the electronic device can determine that its working environment is a shallow water environment. In this embodiment, the electronic device can determine whether to perform depth detection based on the water entry detection result after the water entry detection is completed. For example, the electronic device can perform depth detection after determining that its working environment is a liquid environment. If the electronic device determines that its working environment is an air environment, it can skip depth detection. For example, in response to determining that its working environment is a liquid environment, the electronic device can acquire depth values ​​collected by a depth sensor to perform depth detection. When the electronic device determines that the depth value is greater than or equal to a depth threshold, it can determine that it is in a deep water environment. When the depth value is less than a depth threshold, it can determine that it is in a shallow water area (i.e., a shallow water environment) within the liquid environment, and not in a deep water area. A shallow water area can refer to a shallow body of water, such as a swimming pool or pond with a depth of 0-5 meters. In this way, the electronic device can acquire the depth value collected by the depth sensor only after determining that the working environment of the electronic device is a liquid environment, which can avoid acquiring the depth value when the working environment of the electronic device is an air environment, thereby reducing the power consumption of the electronic device.

[0094] After determining the working environment of the electronic device, it can select the microphone or underwater acoustic transducer corresponding to the current working environment to collect sound based on the current working environment of the electronic device.

[0095] S202: When the working environment of the electronic device is the second environment, the electronic device collects sound through the microphone.

[0096] S203: When the working environment of the electronic device is the first environment, the electronic device collects sound through the underwater acoustic transducer.

[0097] The first environment can include a liquid environment and a deep-water environment. The second environment can include an air environment and a shallow-water environment. For example, when the electronic device's operating environment is a liquid environment, it can collect sound using a hydroacoustic transducer; or, when the operating environment is a deep-water environment, it can collect sound using a hydroacoustic transducer. In this embodiment, the electronic device collects sound in different environments in three main ways. One way is that when the electronic device's operating environment is an air environment, it collects sound using a microphone; when the electronic device's operating environment is a liquid environment (including shallow and deep-water environments), it collects sound using a hydroacoustic transducer. Another way is that when the electronic device's operating environment is an air environment, it collects sound using a microphone; when the electronic device's operating environment is a shallow-water environment, it collects sound using a microphone; and when the electronic device's operating environment is a deep-water environment, it collects sound using a hydroacoustic transducer. Furthermore, when the first depth threshold and the second depth threshold are different, when the depth value of the electronic device is less than the first depth threshold and greater than or equal to the second depth threshold, the electronic device's operating environment can be an intermediate environment. The intermediate environment refers to a liquid environment situated between shallow and deep water environments. When the electronic device operates in an intermediate environment, it can directly receive sound from the microphone or underwater acoustic transducer without switching its pickup path. For example, when the electronic device switches from a deep water environment to an intermediate environment, it can collect sound through the underwater acoustic transducer until its operating environment changes to shallow water. Similarly, when it switches from a shallow water environment to an intermediate environment, it can collect sound through the microphone until its operating environment changes to deep water. Another way the electronic device collects sound is as follows: when the operating environment is air, it collects sound through the microphone; when the operating environment is deep water, it collects sound through the underwater acoustic transducer; and when the operating environment is shallow water, it can collect sound through either the underwater acoustic transducer or the microphone.

[0098] Therefore, when collecting sound, electronic devices can select the appropriate microphone or underwater acoustic transducer based on their operating environment. When the operating environment changes, the electronic device can also switch between the microphone and the underwater acoustic transducer accordingly.

[0099] In some embodiments, such as Figure 3As shown, the electronic device further includes a first path, a second path, and a processor. The microphone is connected to the first path, the second path is connected to the underwater acoustic transducer, and the processor is connected to the water ingress detection sensor, the depth sensor, the first path, and the second path. The processor of the electronic device can detect the operating environment of the electronic device through the water ingress detection sensor and the depth sensor. The processor of the electronic device can select to collect sound through the microphone or the underwater acoustic transducer according to the operating environment. The first path and the second path are the sound pickup paths in the electronic device, used to receive the sound collected by the electronic device. For example, the processor can receive the sound collected by the microphone through the first path, and the processor can receive the sound collected by the underwater acoustic transducer through the second path. In this embodiment, the second path may also include a filtering circuit, which may include a filter and an amplifier. The filtering circuit is used to filter the sound collected by the underwater acoustic transducer. For example, the processor of the electronic device can collect sound from the surrounding environment in different environments in the following ways.

[0100] The processor of an electronic device can detect the operating environment of the electronic device in response to a user-triggered audio pickup operation. For example, the way the processor detects the operating environment is the same as the way the electronic device detects its operating environment in the above embodiments, and will not be repeated here.

[0101] When the electronic device operates in a secondary environment, its processor can collect sound via a microphone. In this case, the electronic device can also perform water immersion detection and / or deep-water detection to switch pathways and ensure sound acquisition quality under different environments when the operating environment changes.

[0102] As an example, when electronic devices detect their operating environment using water immersion detection methods, such as... Figure 4 As shown, taking the case where the electronic device's working environment is an air environment and the processor of the electronic device collects sound through a microphone as an example, the process of sound collection by the processor of the electronic device is explained.

[0103] S401: The processor collects sound through a microphone.

[0104] As an example, a processor can collect sound via a microphone when it determines that the operating environment of the electronic device is an air environment. For instance, the processor can receive the sound collected by the microphone through a first channel.

[0105] S402: The processor acquires environmental parameters collected by the water ingress detection sensor.

[0106] During the sound acquisition process, the processor can also acquire environmental parameters collected by the water immersion detection sensor in real time to detect water immersion in electronic devices and determine whether the working environment of the electronic devices has changed from an air environment to a liquid environment.

[0107] S403: The processor determines whether the environmental parameters are less than the set threshold; if yes, then proceed to step S401; if no, then proceed to step S404.

[0108] S404: The processor collects sound through an underwater acoustic transducer.

[0109] In some embodiments, when environmental parameters are less than a set threshold, the processor can determine that the current operating environment of the electronic device is a liquid environment. When the processor determines that the operating environment of the electronic device has switched from an air environment to a liquid environment, the processor receives the sound collected by the underwater acoustic transducer through a second path. For example, when the processor determines that the operating environment has switched from an air environment to a liquid environment, it can switch the sound pickup path from the first path to the second path and receive the sound collected by the underwater acoustic transducer through the second path.

[0110] For example, when switching the audio pickup path, the processor can achieve this by disconnecting the first path and connecting the second path. In this way, each of the first and second paths can contain a switch. When the processor determines that the electronic device's operating environment is air, it can close the switch in the first path and open the switch in the second path. This allows the processor to connect the first path and disconnect the second path, enabling it to receive sound from the microphone through the first path. As another example, when the processor determines that the electronic device's operating environment has changed from air to a liquid environment, it can open the switch in the first path and close the switch in the second path, switching the connected audio pickup path from the first path to the second path. This allows the processor to receive sound from the underwater acoustic transducer through the second path.

[0111] For example, the processor can also switch the pickup path by disconnecting from the first and second paths. For instance, as... Figure 5 As shown, the electronic device may also include a single-pole double-throw switch. The common terminal A of the single-pole double-throw switch is connected to the processor, the throwing terminal B is connected to the second path, and the throwing terminal C is connected to the first path. In this way, the processor can select the appropriate port to close based on the operating environment of the electronic device, and receive sound from a microphone or underwater acoustic transducer through the pickup path.

[0112] When the processor uses the underwater acoustic transducer to collect sound, it can also acquire environmental parameters in real time from the depth immersion detection sensor to determine whether the electronic device's current operating environment is still liquid. This allows the processor to promptly switch the sound pickup path and use the microphone to collect sound when the operating environment changes from liquid to air, thus ensuring the sound acquisition quality of the electronic device.

[0113] As another example, when electronic devices detect their operating environment through water immersion detection and depth detection, such as... Figure 6 As shown, taking the current working environment of electronic devices as an air environment and the processor of electronic devices collecting sound through a microphone as an example, the process of sound collection by the processor of electronic devices is explained.

[0114] S601: The processor collects sound through a microphone.

[0115] As an example, a processor can collect sound via a microphone when it determines that the operating environment of the electronic device is an air environment. For instance, the processor can receive the sound collected by the microphone through a first channel.

[0116] S602: The processor acquires environmental parameters collected by the water ingress detection sensor.

[0117] During the sound acquisition process, the processor can also acquire environmental parameters collected by the water immersion detection sensor in real time to detect water immersion in electronic devices and determine whether the working environment of the electronic devices has changed from an air environment to a liquid environment.

[0118] S603: The processor determines whether the environmental parameters are less than the set threshold; if yes, then execute step S601; if no, then execute step S604.

[0119] As an example, when the processor determines that the environmental parameters are less than a set threshold, it can determine that the working environment of the electronic device is still an air environment and continue to execute step S601.

[0120] As another example, when the processor determines that the environmental parameters are greater than or equal to a set threshold, it can determine that the operating environment of the electronic device is a liquid environment, at which point the operating environment of the electronic device has changed. The processor needs to execute step S604 to further determine whether the operating environment of the electronic device is a deep water environment within a liquid environment, and thus determine whether it is necessary to switch the pickup path.

[0121] S604: The processor acquires the depth values ​​collected by the depth sensor.

[0122] S605: The processor determines whether the depth value is less than the second depth threshold; if yes, then execute step S601; if no, then execute step S606.

[0123] As an example, when the processor determines that the depth value is less than a second depth threshold, it can determine that the current environment of the electronic device is a shallow water environment, not a deep water environment. Since the electronic device is in a liquid environment, but not a deep water environment, the processor of the electronic device collects sound through a microphone. Therefore, the processor can subsequently execute step S601.

[0124] As another example, when the processor determines that the depth value of the electronic device is greater than or equal to a first depth threshold, it can determine that the current operating environment of the electronic device is a deep-water environment. At this time, the processor needs to switch the sound pickup path, switching from collecting sound through a microphone to collecting sound through an underwater acoustic transducer.

[0125] It should be noted that the first depth threshold and the second depth threshold can be different or the same, and this application embodiment does not limit this. Specifically, when the first depth threshold and the second depth threshold are different, if the processor determines that the depth value of the electronic device is greater than or equal to the second depth threshold and less than the first depth threshold, it can determine that the current operating environment of the electronic device has left the deep water environment but has not entered the shallow water environment. In this case, the processor can determine that the operating environment of the electronic device can be an intermediate environment, and there is no need to switch the sound pickup path.

[0126] S606: The processor collects sound through an underwater acoustic transducer.

[0127] As an example, when the depth value is greater than or equal to a first depth threshold, the processor can determine that the current operating environment of the electronic device is a deep-water environment. When the processor determines that the electronic device has entered a deep-water environment within a liquid environment, it can switch the sound pickup path from the first path to the second path to receive the sound collected by the underwater acoustic transducer through the second path. The switching method of the sound pickup path is the same as described above. Figure 4 The switching method of the pickup path in the embodiments described above is the same, and will not be repeated here.

[0128] When the processor uses the underwater acoustic transducer to collect sound, it can also acquire the depth value collected by the depth sensor in real time to determine whether the current depth value of the electronic device is less than a second depth threshold. In this way, the processor can promptly switch the sound pickup path and collect sound through the microphone when the depth value is less than the second depth threshold, thus ensuring the sound acquisition effect of the electronic device.

[0129] Based on the above embodiments, the electronic device can detect its operating environment using a water immersion detection sensor and a depth sensor. When the operating environment is air or shallow water, it can select to collect sound via a microphone; when the operating environment is deep water, it can select to collect sound via a hydroacoustic transducer. This allows for the use of appropriate devices for sound collection in different environments, ensuring effective sound acquisition. Furthermore, when the operating environment changes, the electronic device can switch its sound pickup path in real time, ensuring good sound pickup of surroundings in various environments and improving the user experience.

[0130] Based on the above embodiments, this application also provides a sound pickup circuit for use in an electronic device. The electronic device can be one of the aforementioned... Figure 1A and Figure 1B The electronic device shown. For example... Figure 7 As shown, the sound pickup circuit may include, but is not limited to, a processing module, a sampling module, a first path, a second path, a microphone, and an underwater acoustic transducer. The processing module is connected to the sampling module, the sampling module is connected to the first and second paths, the first path is connected to the microphone, and the second path is connected to the underwater acoustic transducer. For example, the second path may also include a filtering circuit, which includes a filter and an amplifier.

[0131] The processing module is used to detect the operating environment of the sound pickup circuit. When the operating environment of the sound pickup circuit is a first environment, the processing module can acquire the sound collected by the underwater acoustic transducer through the sampling module. When the operating environment of the sound pickup circuit is a second environment, the processing module can acquire the sound collected by the microphone through the sampling module. The first environment includes liquid environments and deep water environments, while the second environment can include air environments and shallow water environments.

[0132] The sampling module is used to acquire sound collected by a microphone or underwater acoustic transducer through a first or second channel.

[0133] A microphone is used to collect sound.

[0134] A water acoustic transducer is used to collect sound.

[0135] In some embodiments, the processing module and the sampling module in the pickup circuit can be integrated into the same chip or into separate chips.

[0136] As an example, the processing module and the sampling module can be integrated into a separate chip. For instance, such as... Figure 8As shown, the sound pickup circuit also includes a first chip and a second chip. The first chip includes a processing module, and the second chip includes a sampling module. For example, the first chip can be a chip in a processor in an electronic device, and the second chip can be a chip located outside the processor in the electronic device.

[0137] As another example, such as Figure 9 As shown, the pickup circuit also includes a third chip, in which the processing module and sampling module can be integrated. For example, the third chip can be a chip integrated into the processor of an electronic device. For instance, the processing module and sampling module can be integrated into the AP chip within the processor, or into other chips, without limitation. When the processing module and sampling module are integrated into the same chip, the third chip, both the second and first paths are external to the chip where the sampling module and processing module are integrated, and the switch used to switch between the first and second paths is also located externally. For example, as... Figure 10 As shown, the sampling module and processing module in the pickup circuit can be integrated into the AP chip. The sampling module is connected to the common terminal A of the single-pole double-throw switch, the first path is connected to the throwing terminal C of the single-pole double-throw switch, and the second path is connected to the throwing terminal B of the single-pole double-throw switch.

[0138] In some embodiments, when the processing module determines to collect sound from the surrounding environment, it can detect the operating environment of the electronic device and send a collection instruction to the sampling module based on the operating environment. The collection instruction may include a first collection instruction and a second collection instruction. The first collection instruction instructs sound to be collected via a microphone, and the second collection instruction instructs sound to be collected via an underwater acoustic transducer. For example, the processing module can detect the operating environment of the electronic device and send the collection instruction to the collection module in the following ways.

[0139] As an example, the microphone circuit may also include a water ingress detection sensor, which is connected to the processing module. The processing module can acquire environmental parameters collected by the water ingress detection sensor and determine whether the microphone circuit operates in an air environment or a liquid environment based on these parameters. The process by which the processing module determines the operating environment of the microphone circuit using the water ingress detection sensor is the same as the process in the above embodiment where the operating environment of the electronic device is determined by water ingress detection, and will not be described again here.

[0140] When the microphone circuit operates in an air environment, the processing module can send a first acquisition command to the sampling module. When the microphone circuit operates in a liquid environment, the processing module can send a second acquisition command to the sampling module.

[0141] As another example, the microphone circuit may also include a water immersion detection sensor and a depth sensor, with the processing module connected to both. The processing module can acquire environmental parameters collected by the water immersion detection sensor and determine whether the microphone circuit's operating environment is air or liquid based on these parameters. When the microphone circuit's operating environment is liquid, the processing module can acquire the depth value collected by the depth sensor. When the depth value is greater than or equal to a first depth threshold and the microphone circuit's operating environment is liquid, the processing module can determine that the microphone circuit's operating environment is deep water; or, when the depth value is less than a second depth threshold and the microphone circuit's operating environment is liquid, the processing module can determine that the microphone circuit's operating environment is shallow water. The process by which the processing module determines the microphone circuit's operating environment using the water immersion detection sensor and the depth sensor is the same as the process in the above embodiments for determining the electronic device's operating environment using water immersion detection and deep water detection, and will not be repeated here.

[0142] When the microphone circuit operates in an air or shallow water environment, the processing module can send a first acquisition command to the sampling module. When the microphone circuit operates in a deep water environment, the processing module can send a second acquisition command to the sampling module.

[0143] After receiving a acquisition command from the processing module, the sampling module receives sound from the microphone or underwater acoustic transducer through either the first or second channel. For example, upon receiving the first acquisition command, the sampling module can receive sound from the microphone through the first channel and send the received sound to the processing module. Similarly, upon receiving the second acquisition command, the sampling module can also receive sound from the underwater acoustic transducer through the second channel and send the received sound to the processing module. In this way, the processing module can notify the sampling module to switch the pickup channel according to changes in the operating environment of the sound pickup circuit, ensuring sound acquisition quality in different environments.

[0144] Based on the above embodiments, the processing module can detect the working scenario of the sound pickup circuit through the water ingress detection sensor and the depth sensor, and instruct the sampling module to select an appropriate sound pickup path to receive the sound collected by the microphone or the underwater acoustic transducer based on the working scenario of the sound pickup circuit. This enables the sound to be collected in different working scenarios while ensuring the sound collection effect, thereby improving the user experience.

[0145] Based on the above embodiments and the same technical concept, this application also provides an electronic device. This electronic device can be the one described above. Figure 1A and Figure 1BThe electronic device shown is used to implement the sound pickup method provided in the embodiments of this application. The electronic device may include a processor, a microphone, and an underwater acoustic transducer, with the processor connected to the microphone and the underwater acoustic transducer. The processor is used to detect the operating environment of the electronic device. When the operating environment of the electronic device is the first environment, the processor is used to collect sound through the underwater acoustic transducer. When the operating environment of the electronic device is the second environment, the processor is used to collect sound through the microphone.

[0146] A microphone is used to collect sound.

[0147] A water acoustic transducer is used to collect sound.

[0148] In some embodiments, the first environment includes a liquid environment and a deep-water environment. The second environment may include an air environment and a shallow-water environment. For detailed descriptions of the first and second environments in the above embodiments, they will not be repeated here.

[0149] In some embodiments, the electronic device has a built-in depth sensor and a water ingress detection sensor. The depth sensor and the water ingress detection sensor are connected to the processor.

[0150] The process by which the processor in the electronic device executes the sound pickup method is the same as the process by which the electronic device executes the sound pickup method in the above embodiment, and will not be described again here.

[0151] In some embodiments, the electronic device further includes a housing, and the underwater acoustic transducer is disposed within the housing. Exemplarily, the underwater acoustic transducer disposed within the housing can be a MEMS underwater acoustic transducer, which can be placed within a hole in the housing of the diving watch. The hole containing the MEMS underwater acoustic transducer needs to be filled to prevent liquid from seeping into the hole. In this embodiment, because the MEMS underwater acoustic transducer is small and its placement within the housing does not affect the overall thickness of the electronic device, the number of underwater acoustic transducers disposed within the housing can be one or more. Multiple underwater acoustic transducers can be arranged in an array within the housing. The electronic device can also achieve sound source localization based on multiple underwater acoustic transducers.

[0152] For example, such as Figure 11 As shown, when the electronic device is a diving watch with audio function, the MEMS underwater acoustic transducer can be placed in the hole of the diving watch's casing. After the MEMS underwater acoustic transducer is placed in the hole, the hole is filled to obtain a diving watch that can pick up underwater sounds.

[0153] In other embodiments, the electronic device further includes a screen module, in which an underwater acoustic transducer is disposed. The underwater acoustic transducer may be a piezoelectric underwater acoustic transducer. When the underwater acoustic transducer is located within the screen module, it is exposed to the outside of the screen surface without obstruction or need to avoid other devices, has a large area, and provides good sound reception.

[0154] As an example, such as Figure 12 As shown, the screen module includes a glass cover, a touch sensor, a display screen, and an underwater acoustic transducer; the touch sensor is located below the glass cover and above the display screen, and the underwater acoustic transducer is located below the display screen.

[0155] As another example, such as Figure 13 As shown, the screen module may include an underwater acoustic transducer, a touch sensor, and a display screen, with the touch sensor located below the underwater acoustic transducer and above the display screen. The underwater acoustic transducer serves as a glass-like cover within the screen module, possessing characteristics such as light transmission, corrosion resistance, and high hardness. For example, the underwater acoustic transducer can be a transparent piezoelectric ceramic.

[0156] For example, such as Figure 14 As shown, when the electronic device is a watch, the screen module of the electronic device is circular. At this time, the shape of the piezoelectric underwater acoustic transducer is the same as that of the screen module, which is also circular.

[0157] In other embodiments, the underwater acoustic transducer can be integrated into an electronic device. When integrated into an electronic device, the underwater acoustic transducer needs to avoid the arrangement of other components within the electronic device. For example, the electronic device may also include a motor and a heart rate sensor, and the underwater acoustic transducer avoids the arrangement of the motor and heart rate sensor. The underwater acoustic transducer can be a piezoelectric underwater acoustic transducer. The shape of the underwater acoustic transducer integrated into the electronic device is designed to avoid the arrangement of sensors, motors, and other components within the electronic device.

[0158] For example, such as Figure 15 As shown, the electronic device can be a diving watch, and the piezoelectric underwater acoustic transducer can be placed inside the back cover of the diving watch. The sensor module and motor are located inside the back cover of the diving watch. The sensor module may include a heart rate sensor. Figure 15 As shown, the piezoelectric underwater acoustic transducer needs to avoid the sensor module and motor located on the back cover of the diving watch. The shape of the piezoelectric underwater acoustic transducer is designed to avoid these components. The piezoelectric underwater acoustic transducer can also have other shapes, as long as these shapes can avoid the sensor module and motor.

[0159] For example, such as Figure 16As shown, the electronic device is a diving watch, and the piezoelectric underwater acoustic transducer can be placed inside the back cover of the diving watch. There is a recess inside the back cover of the diving watch. The piezoelectric underwater acoustic transducer needs to avoid this recess; therefore, the shape of the piezoelectric underwater acoustic transducer is an irregular ring.
