Description

Technical Field

[0001] The present invention relates to the field of earphones, and in particular to a protection method, device, earphone and computer-readable storage medium for an earphone. Background Art

[0002] In recent years, with the development of social economy and the gradual improvement of people's living standards, TWS (True Wireless Stereo) earphones have gradually come into everyone's view, and people's demands for the sound quality and service life of earphones are also getting higher and higher.

[0003] In actual use, when the earphone with the above diaphragm design suddenly receives the impact of a large excitation signal, it is easy to cause a large instantaneous distortion during the operation of the earphone. In addition, when the earphone suddenly receives the impact of a large excitation signal and makes a large-displacement amplitude movement, it may even cause irreversible damage to the diaphragm such as tearing and reduced flexibility, affecting the service life of the earphone. Summary of the Invention

[0029] A protection method, device, earphone and computer-readable storage medium for an earphone provided by an embodiment of the present invention. When the earphone is in the earphone case, obtain the current temperature of the earphone; determine whether the current temperature is lower than a preset temperature warning value; if the current temperature is lower than the preset temperature warning value, heat the earphone to increase the current temperature of the earphone.

Description of the Drawings

[0031] Figure 1 It is a schematic structural diagram of an operating device of the hardware operating environment involved in the solution of the embodiment of the present invention;

[0032] Figure 2 It is a schematic flowchart of an embodiment of a protection method for an earphone according to the present invention;

[0033] Figure 3 It is an application schematic diagram of an embodiment of a protection method for an earphone according to the present invention.

[0034] The realization, functional characteristics and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the drawings. Detailed Embodiment

[0035] The diameter of the diaphragm in a small-sized speaker is about 16 mm, and the thickness of the diaphragm is about 10 μm. Such a small and thin earphone diaphragm design will make the diaphragm more affected by temperature. When the earphone diaphragm is under too low temperature conditions, it usually causes the flexibility of the diaphragm material to decrease. If a large excitation signal suddenly impacts at this time, it will cause a large instantaneous distortion in the operation of the earphone. In addition, when the earphone suddenly receives a large excitation signal and makes a large displacement amplitude movement, it may even cause irreversible damage to the diaphragm such as tearing and reducing flexibility, affecting the service life of the earphone.

[0036] In addition, the environments in which the earphones are tested during the R & D and testing phases are basically based on ideal temperature environments. When the ambient temperature changes too much, the frequency response and distortion of the earphones cannot achieve the expected effects. That is, the greater the temperature difference between the actual ambient temperature where the earphones are located and the ideal temperature during R & D and testing, the greater the difference between the actual usage data and the laboratory test data, which will profoundly affect the user experience of the earphones.

[0037] Therefore, when the earphones are in the earphone case, after obtaining the temperature of the earphones, it is determined whether the temperature is lower than the preset temperature warning value to determine whether the earphones are in an environment with too low temperature. If so, the diaphragm of the earphones is heated to make it in an appropriate working temperature, so as to reduce the problems of too high transient distortion and shortened service life caused by suddenly working in a low-temperature environment.

[0038] In addition to heating the earphones to make the diaphragm in an appropriate working temperature to reduce the problems of too high transient distortion and shortened service life caused by suddenly working in a low-temperature environment, the diaphragm can also be made to be in a low-frequency working state before suddenly receiving the impact of a large excitation signal. When the user is about to use the earphones, the charging case of the earphones will be opened first. At the moment of opening the charging case, the earphones play a preset signal before being officially worn on the human ear. By playing the preset signal, the earphones are pre-worked to reach a more ideal working state in advance, that is, to achieve the effect of pre-working the earphones at a low amplitude.

[0039] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0068] An embodiment of the present invention provides a protection method for an earphone. Refer to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of a protection method for an earphone according to the present invention.

[0069] In this embodiment, the protection method for the earphone includes:

[0070] Step S10: When the earphone is in the earphone case, obtain the current temperature of the earphone.

[0071] In this embodiment, the type of the earphone is not limited. It can be a dynamic earphone or a balanced armature earphone, or other earphones that generate sound based on the vibration of the diaphragm. In this embodiment, a dynamic earphone is taken as an example for illustration.

[0072] A dynamic earphone is the most common and ordinary earphone. Its driving unit is basically a small dynamic loudspeaker, and the voice coil in the permanent magnetic field drives the connected diaphragm to vibrate. Dynamic earphones have relatively high efficiency and can mostly be driven by the headphone output on the audio system, and are reliable and durable. Vibration is the fundamental cause of sound generation. Then, if sound is to be generated, there must be a vibration source. The thin film inside the earphone is the vibration source. Also, because the guiding coil is attached to the thin film, the guiding coil and the thin film as a whole vibrate as the vibration source, so it is called a dynamic coil. Of course, earphones with a different structure should not be called dynamic coils. Its working principle is actually the basic application of magnetism and electricity in ordinary physics. When a closed coil is in a magnetic field, a change in magnetic flux will generate an electric current. Vice versa, by passing an electric current through the coil, a magnetic field is generated, and the magnetic field interacts with the permanent magnetic material at the bottom to push the vibration of the thin film, and sound is generated. This is the working principle of the dynamic coil.

[0073] Add a temperature sensor in the dynamic coil headphone to monitor the current temperature of the dynamic coil headphone in real time. When the dynamic coil headphone is in the headphone case (charging case), obtain the current temperature of the dynamic coil headphone. Herein, the current temperature of the dynamic coil headphone refers to the temperature on the surface of the dynamic coil headphone or the ambient temperature. Of course, the difference between these two temperatures is not significant. In this embodiment, the acquisition location of the current temperature of the dynamic coil headphone is not limited. The temperature sensor can be installed inside the dynamic coil headphone or in the headphone case. When it is installed in the headphone case, an infrared detection device for determining whether the dynamic coil headphone is in the headphone case can be added. Similarly, when it is determined that the dynamic coil headphone is in the headphone case, obtain the current temperature of the dynamic coil headphone. In this embodiment, the type and installation location of the temperature sensor for monitoring the current temperature of the dynamic coil headphone in real time are not limited, subject to meeting the installation space requirements and temperature measurement accuracy.

[0074] Step S20: Determine whether the current temperature is lower than the preset temperature warning value.

[0075] The preset temperature warning value is a temperature judgment threshold for determining whether the temperature is too low, which is preset based on the applicable operating temperature range of the diaphragm material of the dynamic coil headphone. By determining whether the current temperature of the dynamic coil headphone is lower than the preset temperature warning value, it is determined whether the dynamic coil headphone is in an environment with too low temperature.

[0076] Step S30: If the current temperature is lower than the preset temperature warning value, heat the headphone to raise the current temperature of the headphone.

[0077] In the headphone case, a preheating device is preset, which can be a traditional heating material such as an electric heating wire. In this embodiment, the installation location and heating principle of the headphone preheating device are not limited. When the dynamic coil headphone is placed in an environment with a relatively low temperature and the current temperature of the dynamic coil headphone reaches below the preset temperature warning value, the preheating device in the charging case will heat the dynamic coil headphone through the internal electric heating device, uniformly heating the dynamic coil headphone to the preset target temperature set according to the applicable operating temperature of the headphone diaphragm material, or heating it to within a preset range of the preset target temperature. During the heating period, the headphone can be taken out and worn at any time, and the heating stops when it is taken out. For example, the dynamic coil headphone is heated to the preset target temperature of 25° or 25°±2°. In this embodiment, the determination method and magnitude of the preset target temperature are not limited, and the magnitude of the preset range is not limited, subject to the diaphragm of the dynamic coil headphone being able to work at the applicable operating temperature. In this way, it can effectively avoid excessive transient distortion and unstable diaphragm operation of the dynamic coil headphone in the initial period of operation due to too low temperature, reduce the time for the dynamic coil headphone to reach the normal operating state (normal temperature or temperature range), thereby improving the wearing experience of the user.

[0078] In this embodiment, when the earphone is in the earphone case, obtain the current temperature of the earphone; determine whether the current temperature is lower than a preset temperature warning value; if the current temperature is lower than the preset temperature warning value, heat the earphone to increase the current temperature of the earphone.

[0079] The earphone has a small volume. The diameter of the diaphragm in it is about 16 mm, and the thickness of the diaphragm is about 10 μm. Such a small and thin earphone diaphragm design will cause the diaphragm to be greatly affected by temperature. When the earphone diaphragm is under too low temperature conditions, it usually causes the flexibility of the diaphragm material to decrease. If a large excitation signal suddenly impacts at this time, it will cause a large instantaneous distortion in the earphone during operation. In addition, when the earphone suddenly makes an amplitude movement with a large displacement, it may even cause irreversible damage to the diaphragm such as tearing and reduced flexibility, affecting the service life of the earphone. That is to say, there are technical problems of large instantaneous distortion and short service life of the earphone when using the earphone at low temperature. And the greater the temperature difference between the actual environment temperature where the earphone is located and the ideal temperature in R & D and testing, the greater the difference between the actual use data and the laboratory test data, which will deeply affect the user's experience of using the earphone.

[0080] Therefore, in this embodiment, when the earphone is in the earphone case, after obtaining the current temperature of the earphone, determine whether it is lower than the preset temperature warning value to determine whether the earphone is in an environment with too low temperature. If so, heat the earphone to make the diaphragm of the earphone in an adapted working temperature, thereby reducing the problems of too high instantaneous distortion and shortened service life caused by suddenly working in a low-temperature environment, and at the same time making the ambient temperature where the earphone is actually used close to the ideal temperature during R & D and testing, fitting the ideal working state of the earphone, thereby improving the output performance of the earphone and the user experience.

[0081] Optionally, after the step of heating the earphone to increase the current temperature of the earphone, it further includes:

[0082] Determine whether the earphone case is opened;

[0083] If the earphone case is opened, control the earphone to play a preset signal.

[0084] In addition to heating the dynamic earphone to make the diaphragm of the dynamic earphone in an adapted working temperature, thereby reducing the problems of too high instantaneous distortion and shortened service life caused by suddenly working in a low-temperature environment, it is also possible to make the diaphragm of the dynamic earphone in a low-frequency working state in advance before a large excitation signal suddenly impacts.

[0085] In this embodiment, a preset ultrasonic signal or a preset audio signal that will be called as soon as the headphone case is opened is added to the dynamic coil headphone. When the user is about to use the headphone, the charging case of the dynamic coil headphone will be opened first. At the moment when the charging case is opened, the dynamic coil headphone plays the preset ultrasonic signal or audio signal before being officially worn on the human ear. By making the dynamic coil headphone play the ultrasonic signal or audio signal, the dynamic coil headphone is made to work in advance and reach a more ideal working state, that is, to achieve the effect of making the dynamic coil headphone work at a low amplitude in advance. Among them, the preset ultrasonic signal or the preset audio signal can be played when the headphone case is opened before the preset target temperature is reached. In this embodiment, there is no limitation on whether the preset ultrasonic signal or the preset audio signal needs to be played when the headphone is at the preset target temperature. Therefore, when the headphone is opened in advance before reaching the preset target temperature, the preset ultrasonic signal or the preset audio signal can still be played. In this way, the working state of the diaphragm of the dynamic coil headphone is activated, and the sudden change of the diaphragm from the static state to the large displacement state is avoided, which can reduce the influence of transient distortion, improve the sound quality and user experience of the dynamic coil headphone, and also extend the service life of the dynamic coil headphone.

[0086] In this embodiment, in addition to playing the ultrasonic signal or the audio signal after heating the dynamic coil headphone first, it is also possible to play the ultrasonic signal or the audio signal while heating the dynamic coil headphone, or to heat the dynamic coil headphone alone or play the ultrasonic signal or the audio signal alone. There is no limitation on the order of heating the dynamic coil headphone and playing the ultrasonic signal or the audio signal. Similarly, in this embodiment, there is no limitation on the method of achieving the effect of making the dynamic coil headphone work at a low amplitude in advance.

[0087] Optionally, before the step of heating the headphone to raise the current temperature of the headphone to a preset target temperature, it further includes:

[0088] Determining the preset target temperature of the headphone based on the applicable working temperature range of the diaphragm material of the headphone.

[0089] Before heating the dynamic coil headphone to raise the current temperature of the dynamic coil headphone to the preset target temperature, it is necessary to first determine the specific preset target temperature. Since the physical characteristics of the diaphragm cause the above technical problems in the low-temperature environment, the preset target temperature of the headphone is determined according to the applicable working temperature range of the diaphragm material of the dynamic coil headphone.

[0090] Optionally, before the step of controlling the headphone to play the preset signal, it further includes:

[0091] Determining the preset signal based on the applicable working amplitude range of the diaphragm material of the headphone.

[0092] Similarly, before controlling the dynamic coil headphone to play a preset signal for a preset playing duration, it is also necessary to first determine the specific playing duration and the amplitude of the preset signal. Since it is the physical characteristics of the diaphragm that cause the above technical problems in the operation under a sudden excitation signal, therefore, the preset playing duration and the signal amplitude of the preset signal are determined according to the applicable working amplitude range of the diaphragm material of the dynamic coil headphone. In this embodiment, the preset playing duration is set to 3 seconds according to the time used in the general process of a user wearing the headphone. During the wearing process, it may be completed in advance, and thus the playing of the preset signal can be stopped in advance, and the action of allowing the dynamic coil headphone to work at a low amplitude in advance can be stopped in advance.

[0093] Optionally, after the step of controlling the headphone to play the preset signal, the method further includes:

[0094] judging whether the headphone is worn when playing the preset signal;

[0095] If so, controlling the headphone to stop playing the preset signal.

[0096] After controlling the dynamic coil headphone to play a preset signal for a preset playing duration, if the dynamic coil headphone is worn within the preset playing duration, there is no need to continue playing the preset signal, and the dynamic coil headphone is controlled to stop playing the preset signal and prepare to play the audio selected by the user.

[0097] Optionally, after the step of judging whether the current temperature is lower than the preset temperature warning value, the method further includes:

[0098] If the current temperature is not lower than the preset temperature warning value, then execute the step of judging whether the headphone case is opened.

[0099] After judging whether the current temperature is lower than the preset temperature warning value, if it is determined that the current temperature is not lower than the preset temperature warning value, there is no need to heat the dynamic coil headphone, but it is necessary to monitor and judge whether the headphone case is opened to determine whether it is necessary to play a preset ultrasonic signal.

[0100] Optionally, after the step of judging whether the headphone case is opened, the method further includes:

[0101] If the headphone case is not opened, then execute the step of judging whether the current temperature is lower than the preset temperature warning value.

[0102] If the judgment result of whether the headphone case is opened is that the headphone case is not opened, it means that the dynamic coil headphone has not been taken out and has been in the headphone case all the time. Its current temperature may drop, so it is necessary to continue to monitor the current temperature of the dynamic coil headphone. Similarly, when its current temperature is too low, heat the dynamic coil headphone.

[0103] Refer to Figure 3 , Figure 3 which is an application schematic diagram of an embodiment of a protection method for a kind of earphone of the present invention.

[0104] (1) First, place a temperature sensor for real-time monitoring of temperature inside the moving coil earphone. When the temperature of the moving coil earphone is too low, the temperature of the moving coil earphone collected by the temperature sensor will reach the preset temperature warning value, and then the moving coil earphone will send the information of too low temperature to the charging case.

[0105] (2) After receiving the information of too low temperature transmitted by the moving coil earphone, the charging case turns on the internal heating mode. The heating method can be to use materials such as heating wires to heat up the internal environment of the earphone case, and after the temperature rises, the temperature of the moving coil earphone is adjusted to the preset normal working temperature, that is, the preset target temperature, through heat conduction. By heating the moving coil earphone, the diaphragm of the moving coil earphone is in an adapted working temperature, thereby reducing the problems of too high transient distortion and shortened service life caused by suddenly working in a low-temperature environment. At the same time, the ambient temperature when the earphone is actually used is close to the ideal temperature during R & D and testing, which fits the ideal working state of the earphone, thereby improving the output performance of the earphone and the user experience.

[0106] (3) After the temperature of the moving coil earphone reaches the preset target temperature, the temperature sensor inside the charging case will receive the information that the temperature of the moving coil earphone is appropriate, and then turn off the heating of the earphone case.

[0107] (4) Set a switch at the opening of the charging case of the moving coil earphone. When the user opens the charging case, the moving coil earphone will play an ultrasonic signal that gradually increases in amplitude for about three seconds. This ultrasonic signal cannot be heard by people and is used to play for the moving coil earphone to preheat before playing the formal working signal. The practice of playing the ultrasonic signal in advance effectively avoids the instantaneous distortion and damage to the diaphragm of the moving coil earphone caused by the sudden conversion of the moving coil earphone from a static state to a large-amplitude working state, and thus plays a role in protecting the moving coil earphone and extending the service life of the earphone.

[0108] In addition, the embodiment of the present invention also provides a protection device for an earphone. The protection device for the earphone includes:
