For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

The pressure detection module may detect pressure generated due to swelling of the battery, and thus, deformation of the battery may be detected through the pressure detected by the pressure detection module. However, the provision of a pressure detection module means additional space occupation. For small-sized electronic devices, such as smartwatches, smartbands, etc., the extra space occupied makes the volume of the electronic device difficult to further reduce, which is not favorable for the overall design of the small-sized electronic device.
The embodiment of the application discloses a battery deformation detection method, a battery deformation detection device, battery deformation detection equipment and a storage medium, which can detect the deformation of a battery under the condition of not adding an additional sensor. The following are detailed descriptions.

The battery 16 of the electronic device is located adjacent the rear sound cavity 20 and the baffle 14 separates the battery 16 from the speaker 12. The material of the baffle 14 may include, but is not limited to, foam, and the like. Since the battery 16 is disposed close to the rear sound chamber 20, deformation of the battery may act on the baffle 14, resulting in a change in the volume of the rear sound chamber 20.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a battery deformation detection method according to an embodiment of the present disclosure. The battery deformation detection method can be applied to electronic equipment with computing capability, and the electronic equipment can be a device under test body including a battery under test, or can also be a test device independent of the device under test, but is not limited thereto. The testing device can be a personal computer, an industrial computer, a smart phone and the like, and is not limited specifically. As shown in fig. 2, the battery deformation detection method may include the steps of:
210. the method comprises the steps of acquiring a first audio signal acquired by a sound acquisition device when a first loudspeaker of equipment to be tested outputs a test audio signal.
In this embodiment of the application, an internal cavity structure of the device to be tested may be as shown in fig. 1, and the setting positions of the battery to be tested, the first speaker, and the first rear sound cavity included in the device to be tested may refer to fig. 1, which is not described in detail below. The battery of the equipment to be detected is the battery to be detected with unknown deformation state, and is a detection target.
In this application embodiment, the electronic device can play the test audio signal through the first speaker, and can acquire the audio signal through the sound acquisition device while playing the test audio signal, thereby acquiring the first audio signal. The test audio signal may be any audio signal, and may include, but is not limited to, a frequency sweep signal, a fixed frequency audio signal, a fixed volume audio signal, and the like. The sound collection device may be a device capable of converting a sound signal into an electrical signal, such as a microphone. The sound collection device may be a microphone disposed in the body of the device under test, or may also be a microphone device independent of the device under test, and is not limited specifically. It should be noted that, when the sound collection device is a microphone device independent from the device under test, the electronic device may establish a communication connection with the microphone device, and receive the first audio signal collected by the sound collection device through the communication connection.
220. And acquiring a second audio signal acquired by the sound acquisition device when a second loudspeaker of the standard equipment plays the test audio signal.
In the embodiment of the present application, the internal cavity structure of the standard device may be the same as the internal cavity structure of the device to be tested, and may be as shown in fig. 1. The standard equipment comprises a standard battery, a second loudspeaker and a second back sound cavity, and the arrangement positions can refer to fig. 1. Correspondingly, the second rear sound cavity included by the standard equipment and the first rear sound cavity included by the equipment to be tested have the same structure. However, the standard device includes a battery that is an undeformed standard battery, and the standard battery is in a normal form.
In the embodiment of the application, the device to be tested and the standard device can be controlled to play the same test audio signal. And when the equipment to be tested plays the test audio signal through the second loudspeaker, the microphone is used for collecting the audio signal to obtain a second audio signal.
In one embodiment, the device under test and the standard device may be placed in the same enclosure. Acquiring a test audio signal played by equipment to be tested in the closed device through a sound acquisition device to obtain a first audio signal; and acquiring a test audio signal played by standard equipment in the closed device through the sound acquisition device to obtain a second audio signal. The equipment to be tested and the standard equipment are placed in the sealing device and then the test audio signals are played, so that the environmental noise collected by the sound collection device can be reduced, and the first audio signals and the second audio signals collected by the microphone can restore the sound output when the test audio signals are played by the loudspeaker as much as possible. Referring to fig. 3, fig. 3 is an exemplary diagram of a battery testing environment according to an embodiment of the present disclosure. As shown in fig. 3, the device under test may be placed in an enclosure and controlled to play the test audio signal in the enclosure.
It should be noted that step 220 and step 210 have no logical precedence relationship, and step 220 may be executed after step 210, or step 220 may be executed before step 210. For example, before a battery to be tested of the device to be tested is tested, the standard device may be controlled in advance to play the test audio signal, and the second audio signal is acquired and stored. When the battery to be tested needs to be tested, the second audio signal is read from the pre-stored data.
In one embodiment, the standard device may be a standard sample (gold sample) dedicated to detection, and the standard device and the device under test are two different devices.
In one embodiment, the standard device and the device under test may be different modalities of the same device at different times. For example, the standard device may be in a form of the electronic device immediately after being assembled and shipped, and the device under test may be in a form of the electronic device after being used for a period of time after being shipped and shipped. If the standard equipment and the equipment to be tested are in different forms of the same equipment at different periods, the first loudspeaker and the second loudspeaker are in different forms of the same loudspeaker at different periods, the first rear sound cavity and the second rear sound cavity are in different forms of the same rear sound cavity at different periods, and the battery to be tested and the standard battery are in different forms of the same battery at different periods. That is to say, when a certain piece of equipment leaves a factory, the test audio signal may be played through a speaker (i.e., the second speaker) of the equipment, so as to obtain the second audio signal through the sound collecting device. After the equipment leaves a factory and is used for a period of time, the battery deformation of the equipment needs to be detected, and then a test audio signal can be played through a loudspeaker (namely a first loudspeaker) of the equipment so as to acquire the first audio signal through a sound acquisition device.
230. And determining the deformation of the battery to be tested according to the comparison result of the first audio signal and the second audio signal.
In this application embodiment, the deformation of the battery that awaits measuring can form pressure and act on the baffle, leads to the volume in back sound chamber to change to also can change when the sound that leads to the speaker to broadcast transmits to the external world. Taking the battery bulge as an example, if the battery is in a bulge state, the bulge of the battery will press the baffle, resulting in a smaller volume of the back sound cavity. Referring to fig. 4, fig. 4 is a schematic structural diagram of an internal cavity of an electronic device after a battery bulges according to an embodiment of the present application. The battery 16 bulges pressing up against the baffle 16, resulting in a smaller volume of the rear sound cavity 20. The volume change of the back sound cavity can cause the audio frequency transmitted to the outside through the sound outlet to change, and the bulge of the battery can extrude the baffle plate, so that the volume of the back sound cavity is reduced. When the volume of the rear sound chamber 20 becomes small, the propagation path of sound in the rear sound chamber changes, resulting in a change in sound propagated to the outside. Therefore, the second audio signal collected from the standard equipment can be used as a comparison standard, and the deformation of the battery to be tested can be determined according to the comparison result of the first audio signal and the second audio signal.
It can be seen that, in the foregoing embodiment, the device under test and the standard device may be controlled to play the same test audio signal, and the deformation of the battery under test may be determined by comparing the first audio signal played by the device under test and the second audio signal played by the standard device. Furthermore, when the first audio signal and the second audio signal are different, the battery to be tested of the device to be tested is determined to be in a bulging state, so that bulging of the battery can be accurately detected, an additional sensing module is not required, the space of the device can be saved, and the size of the electronic device can be reduced.
Referring to fig. 5, fig. 5 is a schematic flow chart illustrating another method for detecting battery deformation according to an embodiment of the present disclosure, where the method is applicable to the electronic device. As shown in fig. 5, the battery deformation detection method may include the steps of:
510. the method comprises the steps of acquiring a first audio signal acquired by a sound acquisition device when a first loudspeaker of equipment to be tested outputs a test audio signal.
520. And acquiring a second audio signal acquired by the sound acquisition device when a second loudspeaker of the standard equipment plays the test audio signal.
In the embodiment of the present application, the implementation of steps 510 to 520 may refer to the description of steps 210 to 220 in the foregoing embodiment, and the following description is omitted.
530. And comparing the audio parameters corresponding to the first audio signal and the second audio signal.
540. And when the audio parameter of the first audio signal is inconsistent with the audio parameter of the second audio signal, determining that the battery to be tested is in a bulging state.
In the embodiment of the present application, audio parameters corresponding to the first audio signal and the second audio signal may be compared, and the audio parameters may include, but are not limited to: volume, power, frequency response. When the audio parameter of the first audio signal is not consistent with the audio parameter corresponding to the second audio signal, it can be determined that the battery to be tested in the device to be tested is in a bulging state. Wherein the first audio signal and the second audio signal should be compared using corresponding audio parameters. For example, the volume of the first audio signal and the second audio signal is compared, or the power of the first audio signal and the second audio signal is compared.
In one embodiment, the audio parameters for comparison may be determined from the test audio signal. For example, if the test audio signal is an audio signal with a fixed volume, the volumes of the first audio signal and the second audio signal may be compared. If the test audio signal is a swept frequency signal, the frequency responses of the first audio signal and the second audio signal may be compared.
550. And determining the deformation degree of the first rear sound cavity according to the audio parameter corresponding to the first audio signal, the audio parameter corresponding to the second audio signal and the corresponding relation between the pre-calibrated rear sound cavity volume and the audio parameter.
In the embodiment of the application, the measured values of the volumes of the back sound cavities of a large number of sample devices and the audio parameters of the audio signals played by the sample devices can be collected in advance, so that the corresponding relation between the volumes of the back sound cavities and the audio parameters is constructed. For example, a correspondence between the volume of the back cavity and the volume of the audio signal may be constructed; alternatively, a correspondence between the back cavity volume and the power of the audio signal may be constructed. It should be noted that the structure of the back sound cavity in the sample device may be the same as the structure of the back sound cavity in the device to be tested, and the setting position of the speaker in the sample device may be the same as the setting position of the speaker in the device to be tested, so as to improve the reliability of the constructed correspondence between the volume of the back sound cavity and the audio parameter.
In one embodiment, the sample device may be a defective device in which the battery has been deformed, for example, the sample device may be a defective device in which the battery is in a swelled state. Correspondingly, the structure in third back sound chamber that inferior equipment includes can be the same with the structure in first back sound chamber of the equipment that awaits measuring, and the third speaker of inferior equipment can set up in third back sound chamber, and the battery that inferior equipment has been deformed can be close to third back sound chamber and set up. The electronic equipment can acquire a third audio signal acquired by the sound acquisition device when a third loudspeaker of the defective equipment plays the test audio signal, and extract an audio parameter of the third audio signal. After obtaining the audio parameters of the plurality of third audios and the corresponding volume measurement values of the third rear sound cavity, the electronic device may construct a corresponding relationship between the rear sound cavity volume and the audio parameters. The volume measurement value of the third back sound cavity may be entered into the electronic device by a measurement person, but is not limited thereto.
In the embodiment of the application, the electronic device may determine the first rear sound cavity volume according to the audio parameter corresponding to the first audio signal and the corresponding relationship between the pre-calibrated rear sound cavity volume and the audio parameter; determining a second back sound cavity volume according to the audio parameters corresponding to the second audio signals and the corresponding relation between the pre-calibrated back sound cavity volume and the audio parameters; and determining the deformation degree of the first back sound cavity according to the absolute value of the difference between the volumes of the first back sound cavity and the second back sound cavity.
560. And determining the deformation degree of the battery to be tested according to the deformation degree of the first rear sound cavity.
In this application embodiment, because the volume change of first back sound chamber is because the deformation of the battery that awaits measuring leads to, consequently can directly determine the deformation degree of first back sound chamber as the deformation degree of the battery that awaits measuring.
In one embodiment, the deformation of the battery to be tested acts on the baffle, resulting in a change in the volume of the back sound cavity due to the deformation of the baffle. Therefore, the deformation degree of the battery to be tested can be determined by combining the deformation degree of the first rear sound cavity and the deformation coefficient of the baffle.
In one embodiment, after the electronic device performs step 560 to determine the deformation volume of the battery under test, a prompt message may be output when the deformation volume of the battery under test exceeds a volume threshold. The volume threshold value can be determined by referring to the acceptable deformation volume of the battery within the safety range, and when the deformation volume of the battery to be tested is smaller than or equal to the volume threshold value, the deformation degree of the battery to be tested is considered to be low, and no safety problem exists temporarily; when the deformation volume of the battery to be tested exceeds the volume threshold, the deformation degree of the battery to be tested is considered to be high, and safety problems such as explosion, fire and the like can be caused, so that the electronic equipment can output prompt information. The prompt information can be used for prompting the user to stop using the equipment to be tested, or prompting the user to replace a battery and the like so as to reduce safety risks.
In the foregoing embodiment, the battery to be tested is determined to be in the bulging state by comparing the audio parameter of the first audio signal with the audio parameter of the second audio signal, so that the bulging of the battery can be accurately detected without providing an additional sensing module. Furthermore, the deformation degree of the battery can be determined based on the first audio signal and the second audio signal, and safety risks caused by battery deformation are reduced.
Referring to fig. 6, fig. 6 is a schematic flow chart illustrating another method for detecting battery deformation according to an embodiment of the present disclosure, where the method is applicable to the electronic device. As shown in fig. 6, the battery deformation detection method may include the steps of:
610. the method comprises the steps of acquiring a first audio signal acquired by a sound acquisition device when a first loudspeaker of equipment to be tested outputs a test audio signal.
620. And acquiring a second audio signal acquired by the sound acquisition device when a second loudspeaker of the standard equipment plays the test audio signal.
In the embodiment of the present application, the implementation of steps 610 to 620 may refer to the description of steps 210 to 220 in the foregoing embodiment, and details are not repeated below.
630. A first low frequency peak frequency of the frequency response curve of the first speaker is determined from the frequency response of the first audio signal, and a second low frequency peak frequency of the frequency response curve of the second speaker is determined from the frequency response of the second audio signal.
In this embodiment, when the first speaker plays the audio signal to be tested, a relationship that the sound pressure and the phase of the output first audio signal change with the frequency change of the audio signal to be tested may be referred to as a frequency response of the first audio signal, where the frequency response is an audio parameter. Accordingly, when the second speaker plays the audio signal to be tested, the relationship between the sound pressure and the phase of the output second audio signal, which changes with the frequency change of the audio signal to be tested, can show the frequency response of the second audio signal.
When the frequency of the test audio signal changes within a certain frequency range, a frequency response curve of the first loudspeaker can be determined based on the frequency response of the first audio signal corresponding to the multiple frequency points; and a frequency response curve of the second speaker may be determined based on the frequency responses of the second audio signal corresponding to the plurality of frequency points.
In the embodiment of the present application, the low frequency peak of the frequency response curve may refer to a peak of the frequency response curve in a low frequency range, and the low frequency range may refer to a frequency range corresponding to a bass in the audio frequency, and may be, for example, 15 hertz (Hz) to 5000 Hz. Thus, the first low frequency peak frequency may refer to a frequency corresponding to a low frequency peak in a frequency response curve of the first speaker; the second low frequency peak frequency may refer to a frequency corresponding to a low frequency peak in a frequency response curve of the second speaker.
640. And when the difference value between the first low-frequency peak frequency and the second low-frequency peak frequency exceeds a preset threshold value, determining that the battery to be tested is in a bulging state.
In the embodiment of the present application, the influence of the volume change of the rear sound cavity on the output audio includes: as the volume of the back volume cavity increases, the low frequency peaks of the frequency response curve of the output audio gradually move to the left, i.e. appear at lower frequencies. Referring to fig. 7, fig. 7 is a diagram illustrating an exemplary variation relationship between a back cavity volume and a frequency response according to an embodiment of the present application. As shown in fig. 7, the abscissa has no frequency, the ordinate is the sound pressure level, and the abscissa includes 4 different frequency response curves, which are respectively the frequency response curves corresponding to the volume of the back sound cavity of 0.5 Cubic Centimeter (CC), 1CC, 5CC, and 45 CC. When the volume of the back sound cavity is 0.5CC, the low-frequency wave peak of the frequency response curve is at the rightmost side of the 4 frequency response curves, and when the volume of the back sound cavity is 45CC, the low-frequency wave peak of the frequency response curve is at the leftmost side.
