However, users often forget to manually turn off the headphones when folding them, and often cannot find the power button to turn them on when unfolding them. Therefore, the current system offers poor user convenience when turning headphones on and off. Summary of the Invention

[0024] The processor module is used to control the headphones to be in standby mode when the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal.

[0025] The processor module is also configured to control the headphones to switch from the standby state to the power-off state when the output signal of the third magnetic induction switch changes from the fourth level signal to the third level signal.

[0026] In one embodiment, when the third magnetic induction switch is disposed on the left ear shell, the distance between the third magnetic induction switch and the first magnet is greater than the distance between the first magnetic induction switch and the first magnet.

[0027] When the third magnetic induction switch is installed on the right ear shell, the distance between the third magnetic induction switch and the second magnet is greater than the distance between the second magnetic induction switch and the second magnet.

[0029] The output signal of the magnetic induction switch is detected. When the folding angle of the ear shell is greater than a first preset angle, the magnetic induction switch outputs a first level signal under the triggering of the triggering magnet. When the folding angle of the ear shell is not greater than the first preset angle, the magnetic induction switch outputs a second level signal.

[0040] When the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal, the headset is controlled to be in standby mode, and the speaker is controlled to output a first sound wave signal.

[0041] The second sound wave signal collected by the feedback microphone set on the ear shell is obtained, and the headphone is detected as folded and stored properly based on the signal characteristics of the second sound wave signal.

[0042] Once it is confirmed that the headphones are folded and stowed in place, the headphones are controlled to switch from the standby state to the power-off state.

[0043] In one embodiment, the signal characteristics include signal frequency and signal amplitude; the step of detecting whether the headphones are folded and stowed in place based on the signal characteristics of the second sound wave signal includes:

[0044] If the frequency difference between the second sound wave signal and the first sound wave signal is less than a preset frequency difference, and the amplitude difference between the second sound wave signal and the first sound wave signal is less than a preset amplitude difference, then the headphones are determined to be folded and stored in place.

[0045] If the frequency difference between the second sound wave signal and the first sound wave signal is not less than a preset frequency difference, or the amplitude difference between the second sound wave signal and the first sound wave signal is not less than a preset amplitude difference, it is determined that the headphones are not properly folded.

[0046] In one embodiment, the headband is further provided with a third magnetic induction switch; the step of controlling the headphones to turn off when the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal includes:

[0047] The level signal output by the third magnetic induction switch is detected. When the folding angle of the ear shell is greater than the second preset angle, the third magnetic induction switch outputs a third level signal under the triggering of the triggering magnet. When the folding angle of the ear shell is not greater than the second preset angle, the third magnetic induction switch outputs a fourth level signal. The second preset angle is greater than the first preset angle.

[0048] When the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal, the headset is controlled to be in standby mode.

[0049] When the level signal output by the third magnetic induction switch changes from the fourth level signal to the third level signal, the headset is controlled to switch from the standby state to the power-off state.

[0050] In one embodiment, when the third magnetic induction switch is disposed on the left ear shell, the distance between the third magnetic induction switch and the first magnet is greater than the distance between the first magnetic induction switch and the first magnet.

[0051] When the third magnetic induction switch is installed on the right ear shell, the distance between the third magnetic induction switch and the second magnet is greater than the distance between the second magnetic induction switch and the second magnet.

[0052] Thirdly, this application also provides a headphone switching circuit for use in over-ear headphones, the over-ear headphones including an earcup and a headband, the headband being provided with a trigger magnet; the headphone switching circuit includes:

[0053] At least one magnetic induction switch is disposed on the ear shell. When the folding angle of the ear shell is greater than a first preset angle, the magnetic induction switch outputs a first level signal when triggered by a trigger magnet. When the folding angle of the ear shell is not greater than the first preset angle, the magnetic induction switch outputs a second level signal.

[0054] A signal generation module, connected to all the magnetic induction switches, is used to output a power-on signal to the processor module when the output signal of all the magnetic induction switches changes from a first level signal to a second level signal.

[0055] The processor module is connected to all the magnetic induction switches and the signal generation module respectively, and is used to control the headphones to turn on when the power-on signal is received, and to control the headphones to turn off when the output signals of all the magnetic induction switches change from the second level signal to the first level signal.

[0056] In one embodiment, the headphone switching circuit includes a speaker and a feedback microphone respectively disposed on different ear shells;

[0057] The processor module is also configured to control the headphones to be in standby mode when the output signals of all the magnetic induction switches change from the second level signal to the first level signal, and to control the speaker to output the first sound wave signal;

[0058] The feedback microphone is used to output the acquired second acoustic signal to the processor module;

[0059] The processor module is further configured to control the headphones to switch from the standby state to the power-off state when the signal frequency difference between the second sound wave signal and the first sound wave signal is less than a preset frequency difference, and the signal amplitude difference between the second sound wave signal and the first sound wave signal is less than a preset amplitude difference.

[0060] In the aforementioned headphones, headphone control method, and headphone switch circuit, the headphones include an earcup, a headband, and a processor module. The earcup is connected to the headband and can be folded or unfolded relative to the headband. A magnetic induction switch is provided on the earcup, and a trigger magnet is provided on the headband. When the folding angle of the earcup is greater than a first preset angle, the magnetic induction switch outputs a first-level signal upon triggering by the trigger magnet. When the folding angle of the earcup is not greater than the first preset angle, the magnetic induction switch outputs a second-level signal. Thus, when the processor module detects that the output signal of the magnetic induction switch changes from the first-level signal to the second-level signal, it indicates that the folding angle of the earcup has changed. The folding angle gradually decreases but does not exceed the first preset angle. At this time, the user intends to unfold the headphones for use, and the headphones can be turned on. When the processor module detects that the output signal of the magnetic induction switch changes from the second level signal to the first level signal, it indicates that the folding angle of the ear shell gradually increases and exceeds the first preset angle. At this time, the user intends to fold and store the headphones, and the headphones can be turned off. In this way, this application realizes that by detecting the folded and stored state and the unfolded use state of the headphones, the headphones can be automatically turned on and off without the user having to manually trigger the switch button. Therefore, it can improve the user convenience when turning the headphones on and off. Attached Figure Description

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0073] In some embodiments, a headset is provided. Referring to FIG1, the headset includes a headband 10 and earcups 20 connected to the headband 10. The earcups 20 may include a left earcup 201 and a right earcup 202, and the headband 10 may connect the left earcup 201 and the right earcup 202.

[0074] Specifically, referring to Figures 1-3, the headband 10 includes a headband body and a sliding member 30 connected to the headband body. The sliding member 30 is telescopic relative to the headband body to extend and shorten the headband 10. The headband 10 also includes a rotating member 40, which is rotatably connected to the sliding member 30. The ear shell 20 includes an ear shell body and a connecting mechanism 50 connected to the ear shell body. The connecting mechanism 50 is rotatably connected to the end of the rotating member 40 away from the sliding member 30. Specifically, the connecting mechanism 50 is rotatably connected via a pin 60, allowing the connecting mechanism 50 to rotate around the pin 60, thereby achieving the purpose of folding the ear shell 20.

[0075] The headphones in this embodiment are connected in a three-section manner, consisting of a slider 30, a rotating component 40, and a connecting mechanism 50, which ensures that the headphones can be folded for storage or unfolded for use. Referring to Figure 2, Figure 2 shows the folded and stored posture of the headphones in Figure 1.

[0076] Referring further to Figure 3, a trigger magnet 70 is provided on the headband 10, and a magnetic induction switch 80 is provided on the ear shell 20. The magnetic induction switch 80 can be provided on the ear shell body or on the connecting mechanism 50 corresponding to the ear shell body, which is not limited here; referring to Figure 4, Figure 4 shows a schematic diagram of the folded state of the headphones when the folding angle of the ear shell 20 is the first preset angle a1; referring to Figure 5, Figure 5 shows a schematic diagram of the folded state of the headphones when the folding angle a2 of the ear shell 20 is greater than the first preset angle a1.

[0077] As shown in Figures 3-5, as the folding angle of the ear shell 20 increases, the distance between the trigger magnet 70 and the magnetic induction switch 80 decreases. Therefore, when the folding angle of the ear shell 20 is greater than the first preset angle, the trigger magnet 70 will trigger the magnetic induction switch 80, causing the magnetic induction switch 80 to output a first level signal. As the folding angle of the ear shell 20 decreases, the distance between the trigger magnet 70 and the magnetic induction switch 80 increases. Therefore, when the folding angle of the ear shell 20 is not greater than the first preset angle, the trigger magnet 70 will not trigger the magnetic induction switch 80, and the magnetic induction switch 80 will output a second level signal. It should be noted that the folding angle of the ear shell 20 in Figure 3 is less than the first preset angle.

[0078] As an example, the magnetic induction switch 80 can be a Hall switch, the first level signal can be a high level signal, and the second level signal can be a low level signal.

[0079] In addition, the aforementioned headphones also include a processor module connected to the magnetic induction switch 80. The processor module can receive the output signal of the magnetic induction module 80. The processor module is configured to: when it detects that the output signal of the magnetic induction switch 80 changes from a first level signal to a second level signal, it indicates that the ear shell 20 is being unfolded. At this time, it can be determined that the user's intention is to unfold and use the headphones, so the headphones can be turned on; when it detects that the output signal of the magnetic induction switch 80 changes from a second level signal to a first level signal, it indicates that the ear shell 20 is being folded. At this time, it can be determined that the user's intention is to fold and store the headphones, so the headphones can be turned off.

[0080] Based on this, the headphones can be automatically turned on and off according to their folded storage state and unfolded usage state, eliminating the need for users to manually trigger the power button, thus improving user convenience when turning the headphones on and off.

[0081] In some embodiments, referring to FIG6, the magnetic induction switch 80 includes a first magnetic induction switch 801 disposed on the left ear shell 201 and a second magnetic induction switch 802 disposed on the right ear shell 202. The first magnetic induction switch 801 and the second magnetic induction switch 802 are respectively connected to the processor module 90A. The first magnetic induction switch 801 and the second magnetic induction switch 802 are also respectively connected to the signal generation module 90B. The signal generation module 90B is connected to the processor module 90A.

[0082] It should be noted that the trigger magnets include the first trigger magnet corresponding to the first magnetic induction switch 801 and the second trigger magnet corresponding to the second magnetic induction switch 802.

[0083] When the folding angle of the left ear shell 201 is greater than the first preset angle, the first magnetic induction switch 801 will be triggered by the first magnet, thereby outputting a first level signal. When the folding angle of the left ear shell 201 is not greater than the first preset angle, the first magnetic induction switch 801 will output a second level signal. When the folding angle of the right ear shell 202 is greater than the first preset angle, the second magnetic induction switch 802 will be triggered by the second magnet, thereby outputting a first level signal. When the folding angle of the right ear shell 202 is not greater than the first preset angle, the second magnetic induction switch 802 will output a second level signal.

[0084] In this way, when the processor module 90A detects that the output signal of the first magnetic induction switch 801 changes from a second level signal to a first level signal, and the output signal of the second magnetic induction switch 802 changes from a second level signal to a first level signal, it can determine that both the left ear shell 201 and the right ear shell 202 are being folded. This can more reliably prove that the user's intention is to fold and store the headphones. Therefore, the headphones can be controlled to turn off at this time to reduce the power consumption of the headphones. Automatic shutdown can be achieved without the user having to manually shut down the headphones, thus improving the user's convenience.

[0085] When the signal generation module 90B detects that the output signal of the first magnetic induction switch 801 changes from a first level signal to a second level signal, and the output signal of the second magnetic induction switch 802 changes from a first level signal to a second level signal, it can determine that both the left earcup 201 and the right earcup 202 are being unfolded. This can more reliably prove that the user's intention is to unfold and use the headphones. Therefore, the headphones can be controlled to turn on at this time, which can realize automatic power-on without the user having to turn them on manually, thus improving the user's convenience.

[0086] It should be noted that when the output signal of the first magnetic induction switch 801 changes from the second level signal to the first level signal, and the output signal of the second magnetic induction switch 802 changes from the second level signal to the first level signal, it can be determined that both the left ear shell 201 and the right ear shell 202 are being folded, and the user likely intends to store the headphones, but it cannot be proven that the headphones have been properly stored.

[0087] In some embodiments, referring to FIG7, the headphones further include a speaker 90C and a feedback microphone 90D, both of which are connected to the processor module 90A, and the speaker 90C and the feedback microphone 90D are respectively disposed in different ear shells.

[0088] It should be noted that if the speaker 90C is located inside the left ear shell 201, then the rear-feed microphone 90D is located inside the right ear shell 202; if the speaker 90C is located inside the right ear shell 202, then the rear-feed microphone 90D is located inside the left ear shell 201.

[0089] In this way, when the processor module 90A detects that the output signal of the first magnetic induction switch 801 changes from the second level signal to the first level signal, and the output signal of the second magnetic induction switch 802 changes from the second level signal to the first level signal, it can first control the headphones to be in standby mode and control the speaker 90C to output the first sound wave signal.

[0090] When the headphones are in standby mode, they will stop working but will not be turned off. For example, the headphones will exit noise cancellation mode and stop playing music. The first sound wave signal can be an infrasound signal.

[0091] While the speaker 90C outputs the first sound wave signal, the feedback microphone 90D collects ambient sound signals, thus forming a second sound wave signal. It should be noted that as the earcups 20 are continuously folded, the second sound wave signal collected by the feedback microphone 90D will become increasingly similar to the first sound wave signal. After the headphones are folded and stored in place, as shown in Figure 2, the left earcup 201 and the right earcup 202 will fit together. At this time, due to the sound insulation effect of the earcups 20, most of the sound signals collected by the feedback microphone 90D are basically from the first sound wave signal. At this time, the signal characteristics of the second sound wave signal are basically the same as those of the first sound wave signal, and it can be determined that the headphones are stored in place.

[0092] Based on this, the processor module 90A can acquire the second acoustic signal collected by the feedback microphone 90D, and determine whether the headphones are folded and stored properly according to the signal characteristics of the second acoustic signal. After confirming that the headphones are folded and stored properly, the processor module 90A controls the headphones to turn off, that is, controls the headphones to change from standby state to power off state.

[0093] As an example, the signal characteristics include signal frequency and signal amplitude. If the difference in signal frequency between the second sound wave signal and the first sound wave signal is less than a preset frequency difference, and the difference in signal amplitude between the second sound wave signal and the first sound wave signal is less than a preset amplitude difference, it can be determined that the headphones are folded and stored in place.

[0094] It should be noted that, due to the energy loss during the propagation of sound signals, the signal frequencies of the first and second sound wave signals will become nearly identical after the headphones are properly stowed. However, the signal amplitude of the second sound wave signal will be smaller than that of the first sound wave signal.

[0095] Thus, in this embodiment, when the output signal of the first magnetic induction switch 801 changes from a second level signal to a first level signal, and the output signal of the second magnetic induction switch 802 changes from a second level signal to a first level signal, it can be determined that both the left earcup 201 and the right earcup 202 are folded, indicating that the user is not using the headphones for the time being. Therefore, the headphones can be put into standby mode to reduce the power consumption of the headphones. The first sound wave signal is output by the speaker 90C, and the signal characteristics of the second sound wave signal collected by the feedback module 90D are used to detect whether the headphones are folded and stored properly. After it is determined that the headphones are folded and stored properly, the headphones are turned off to avoid accidental power-off and improve the accuracy of automatic power-off of the headphones.

[0096] In some embodiments, referring to FIG8, the headphones also include a third magnetic induction switch 803 disposed on the headband 10, the third magnetic induction switch 803 being connected to the processor module 90A.

[0097] As an example, the third magnetic induction switch 803 can be disposed on the left ear shell 201, and the distance between the third magnetic induction switch 803 and the first magnet is greater than the distance between the first magnetic induction switch 801 and the first magnet; in addition, when the folding angle of the left ear shell 201 is greater than the second preset angle, the third magnetic induction switch 803 outputs a third level signal when triggered by the first magnet, and when the folding angle of the left ear shell 201 is not greater than the second preset angle, the third magnetic induction switch 803 outputs a fourth level signal.

[0098] Since the distance between the third magnetic induction switch 803 and the first magnet is greater than the distance between the first magnetic induction switch 801 and the first magnet, the second preset angle will be greater than the first preset angle. That is, compared with the first magnetic induction switch 801, the third magnetic induction switch 803 is triggered when the folding angle of the left ear shell 201 is greater.

[0099] As an example, the third magnetic induction switch 803 can be disposed on the right ear shell 202, and the distance between the third magnetic induction switch 803 and the second magnet is greater than the distance between the second magnetic induction switch 802 and the second magnet; in addition, when the folding angle of the right ear shell 202 is greater than the second preset angle, the third magnetic induction switch 803 outputs a third level signal when triggered by the second magnet, and when the folding angle of the right ear shell 202 is not greater than the second preset angle, the third magnetic induction switch 803 outputs a fourth level signal.

[0100] Since the distance between the third magnetic induction switch 803 and the second magnet is greater than the distance between the second magnetic induction switch 802 and the second magnet, the second preset angle will be greater than the first preset angle. That is, compared with the second magnetic induction switch 802, the third magnetic induction switch 803 is triggered when the folding angle of the right ear shell 202 is greater.

[0101] As an example, the third level signal can be a high level signal, and the fourth level signal can be a low level signal.

[0102] When the output signal of the first magnetic induction switch 801 changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch 802 changes from a second level signal to a first level signal, the processor module 90A can first control the headset to be in standby mode; when the output signal of the third magnetic induction switch 803 changes from a fourth level signal to a third level signal, the processor module 90A controls the headset to switch from standby mode to power off mode.

[0103] Thus, in this embodiment, when the output signal of the first magnetic induction switch 801 changes from a second level signal to a first level signal, and the output signal of the second magnetic induction switch 802 changes from a second level signal to a first level signal, it can be determined that both the left and right earcups 201 and 202 are folded, indicating that the user is not currently using the headphones. Therefore, the headphones can be put into standby mode to reduce power consumption. When the output signal of the third magnetic induction switch 803 changes from a fourth level signal to a third level signal, the folding angle of the earcups 20 is already large enough, and it can be basically determined that the user intends to store the headphones. At this time, the headphones can be turned off, which reduces the probability of accidental power-off and improves the accuracy of automatic power-off.

[0104] In some embodiments, referring to FIG9, a headphone control method is also provided, applied to a headset, the headset including an ear shell and a headband, a magnetic induction switch being disposed on the ear shell, and a trigger magnet being disposed on the headband; the headphone control method includes:

[0105] Step 1001: Detect the output signal of the magnetic induction switch. When the folding angle of the ear shell is greater than the first preset angle, the magnetic induction switch outputs a first level signal under the triggering of the trigger magnet. When the folding angle of the ear shell is not greater than the first preset angle, the magnetic induction switch outputs a second level signal.

[0106] Step 1002: When the output signal of the magnetic induction switch is detected to change from the first level signal to the second level signal, the headset is powered on.

[0107] Step 1003: When the output signal of the magnetic induction switch is detected to change from the second level signal to the first level signal, the headset is controlled to turn off.

[0110] When the folding angle of the right ear shell is greater than the first preset angle, the second magnetic induction switch outputs a first level signal when triggered by the second magnet; when the folding angle of the right ear shell is not greater than the first preset angle, the second magnetic induction switch outputs a second level signal.

[0111] In some embodiments, controlling the headphones to power on when a change in the output signal of the magnetic induction switch from a first level signal to a second level signal is detected includes:

[0112] When the output signal of the first magnetic induction switch changes from a first level signal to a second level signal and the output signal of the second magnetic induction switch changes from a first level signal to a second level signal, the headset is powered on.

[0113] In some embodiments, controlling the headphones to turn off when a change in the output signal of the magnetic induction switch from a second level signal to a first level signal is detected includes:

[0114] When the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal, the headset is controlled to turn off.

[0115] In some embodiments, the headphones further include a speaker and a feedback microphone, the speaker and the feedback microphone being disposed in different ear shells; controlling the headphones to turn off when the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal is detected, including:

[0116] When the output signal of the first magnetic induction switch changes from the second level signal to the first level signal and the output signal of the second magnetic induction switch changes from the second level signal to the first level signal, the headset is controlled to be in standby mode and the speaker is controlled to output the first sound wave signal.

[0117] The system acquires the second acoustic signal collected by the feedback microphone on the earcup, and detects whether the headphones are folded and stored properly based on the signal characteristics of the second acoustic signal.

[0118] Once the headphones are properly folded and stored, control the headphones to switch from standby mode to power off mode.

[0119] In some embodiments, the signal characteristics include signal frequency and signal amplitude; detecting whether the headphones are folded and stowed in place based on the signal characteristics of the second sound wave signal includes:

[0120] If the frequency difference between the second sound wave signal and the first sound wave signal is less than a preset frequency difference, and the amplitude difference between the second sound wave signal and the first sound wave signal is less than a preset amplitude difference, then the headphones are determined to be folded and stored in place.

[0121] If the frequency difference between the second and first sound wave signals is not less than a preset frequency difference, or the amplitude difference between the second and first sound wave signals is not less than a preset amplitude difference, it is determined that the headphones are not properly folded.

[0122] In one embodiment, a third magnetic induction switch is further provided on the headband; when the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal, the headset is controlled to turn off, including:

[0123] The level signal output by the third magnetic induction switch is detected. When the folding angle of the ear shell is greater than the second preset angle, the third magnetic induction switch outputs a third level signal under the triggering of the triggering magnet. When the folding angle of the ear shell is not greater than the second preset angle, the third magnetic induction switch outputs a fourth level signal. The second preset angle is greater than the first preset angle.

[0124] When the output signal of the first magnetic induction switch changes from a second level signal to a first level signal and the output signal of the second magnetic induction switch changes from a second level signal to a first level signal, the headset is controlled to be in standby mode.

[0125] When the level signal output by the third magnetic induction switch changes from the fourth level signal to the third level signal, the headset is controlled to switch from standby mode to power off mode.

[0126] In some embodiments, when the third magnetic induction switch is disposed on the left ear shell, the distance between the third magnetic induction switch and the first magnet is greater than the distance between the first magnetic induction switch and the first magnet.

[0127] When the third magnetic induction switch is located on the right ear shell, the distance between the third magnetic induction switch and the second magnet is greater than the distance between the second magnetic induction switch and the second magnet.
