Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of smart devices, and more specifically, to a method for controlling an earphone, an apparatus for controlling an earphone, an earphone, and a computer-readable storage medium. Background Art

[0002] In recent years, in-ear headphones have occupied the vast majority of the market share in active noise reduction headphones due to their compact and portable design and relatively good noise reduction performance. When the noise reduction function of active noise reduction headphones is turned on, the headphones will invert the noise signal collected by the microphone through the noise reduction module, generate an equal and inverted reverse sound wave signal, and play it through the headphones to offset the noise signal, thereby achieving the purpose of active noise reduction.

[0003] However, in active noise reduction headphones, when the user wears the headphones, the user may press the headphones to make them more firmly worn because the headphones are not firmly worn or uncomfortable to wear, but this will cause the air pressure inside the cavity formed by the front sound outlet of the headphones and the inside of the ear canal to increase instantly, which will cause the feedback microphone to misjudge that the received "noise sound pressure" has increased instantly, and then transmit the signal to the noise reduction module, guiding the noise reduction module to generate a larger reverse sound wave signal. However, since the noise signal does not actually increase, but the air pressure inside the ear canal increases, this will make the reverse cancellation signal strength greater than the noise signal strength, resulting in the adverse reaction of negative noise reduction, which is called howling. In the related art, in order to avoid the howling phenomenon in the headphones, the feedback microphone is improved so that the feedback microphone can be temporarily interrupted when it is impacted in the pressure field. However, such an improved design will increase the difficulty of the microphone design, which is not conducive to lightweight and miniaturized design. At the same time, the internal circuit design of the microphone will be more complicated, which will lead to increased costs. Summary of the invention

[0048] <Hardware Configuration>

The earphone 1000 may be an in-ear active noise reduction earphone, which includes a feedback microphone. When the feedback noise reduction function of the active noise reduction earphone is turned on, the earphone will perform inversion processing on the noise signal collected by the feedback microphone through the noise reduction module, and generate an equal and inverted reverse sound wave signal to be played by the earphone to offset the noise signal, thereby achieving the purpose of active noise reduction. The howling phenomenon of the active noise reduction earphone has been introduced in the background technology part, and the embodiment of the present disclosure will not be repeated here.

[0055] Figure 1 The headphones shown are illustrative only and are in no way intended to limit the disclosure, its application, or uses.

[0056] <Method Example>

[0057] Figure 2 The control method of the earphone according to an embodiment of the present disclosure is shown. The earphone may be an in-ear active noise reduction earphone. The earphone may include a housing and an infrared sensor disposed on the housing. The control method of the earphone may be performed by, for example, Figure 1 The headset 1000 is shown as an implementation.

[0058] like Figure 2 As shown, the headset control method in this embodiment may include the following steps S2100 to S2200:

[0059] Step S2100: When the earphone is worn, the infrared sensor is used to detect whether a human hand presses the housing.

[0060] In an in-ear active noise reduction headset, when a user wears the headset, the user may press the headset to achieve a more secure wearing because the headset is not firmly worn or uncomfortable to wear, but this will cause the air pressure inside the cavity formed by the front sound outlet of the headset and the inside of the ear canal to increase instantaneously, and then cause the feedback microphone to misjudge that the received "noise sound pressure" has increased instantaneously, and then transmit the signal to the noise reduction module, guiding the noise reduction module to generate a larger reverse sound wave signal. However, since the noise signal does not actually increase, but the air pressure inside the ear canal increases, this will make the reverse cancellation signal strength greater than the noise signal strength, resulting in an adverse reaction of negative noise reduction, which is called howling. Here, in this embodiment, when the user wears the headset, the infrared sensor on the headset shell will detect whether the headset shell is pressed by a human hand. If the headset shell is pressed by a human hand, the feedback noise reduction intensity of the headset is reduced or the feedback noise reduction function of the headset is turned off, so as to prevent howling caused by excessive feedback noise reduction intensity.

[0061] In this embodiment, the infrared sensor includes an infrared light sensor and an infrared temperature sensor. Here, in step S2100, when the headset is worn, detecting whether a hand presses the housing by the infrared sensor may further include the following steps S2110 to S2130:

[0062] Step S2110: When wearing the earphone, use the infrared light sensor to detect whether there is any obstruction on the housing.

[0063] In this step S2110, two infrared sensors are added to the earphone housing to detect whether the earphone housing is in a state where a person presses the earphone housing. One of the infrared sensors is an infrared light sensor, which includes an infrared light transmitter and an infrared light receiver. Specifically, when the user wears the earphone, the infrared light transmitter can emit an infrared light signal, and according to the infrared light signal received by the infrared light receiver, it can be determined whether there is an obstruction on the earphone housing.

[0064] For example, when a user wears headphones, if there is an obstruction blocking the headphone housing, after the headphones transmit an infrared light signal through the infrared light transmitter, the infrared light receiver of the headphones cannot receive the infrared light signal, and thus it can be determined that there is an obstruction on the headphone housing.

[0065] Step S2120: When it is detected that there is an obstruction on the housing, the temperature of the obstruction detected by the infrared temperature sensor is obtained.

[0066] In this step S2120, another infrared sensor of the earphone housing is an infrared temperature sensor. Since it can only be determined whether there is an obstruction on the earphone housing according to the above step S2110, the obstruction here can be items such as the user's hair and jewelry. In order to prevent the false judgment of the infrared light sensor being blocked by items such as hair and jewelry, the infrared temperature sensor will be activated after the infrared light sensor determines that there is an obstruction blocking the earphone housing. The infrared temperature sensor is used to determine the temperature of external obstructions. Since the infrared thermal imaging images of objects such as clothing and hair are different from the infrared thermal imaging images of human hands, the infrared temperature sensor can determine the temperature of the obstruction based on the infrared thermal imaging images.

[0067] Step S2130: When the detected temperature of the shielding object matches the temperature of a human hand, it is determined that the human hand is detected pressing the housing.

[0068] In this step S2130, when the infrared temperature sensor determines that the temperature of the obstruction matches the temperature of a human hand according to the infrared thermal imaging image, it can be determined that a human hand is pressing the earphone housing.

[0069] According to the above steps S2110 to S2130, two progressive infrared sensors are used to determine whether a human hand touches the earphone housing, which can provide detection accuracy.

[0070] Step S2200: when it is detected that a person is manually pressing the housing, the feedback noise reduction intensity of the headset is reduced or the feedback noise reduction function of the headset is turned off to prevent the headset from generating howling.

[0071] In one example, when it is detected that someone is pressing the earphone housing, the earphone will reduce its own feedback noise reduction intensity or turn off the feedback noise reduction function of the earphone to prevent howling caused by the instantaneous increase in feedback noise reduction intensity.

[0072] In one example, the earphone further includes a sound outlet and a pressure sensor, and the pressure sensor is disposed near the sound outlet. Here, in the case where it is detected that a person is pressing the housing, step S2200 reduces the feedback noise reduction intensity of the earphone or turns off the feedback noise reduction function of the earphone to prevent the earphone from generating howling, and can further include the following steps S2210 to S2220:

[0073] Step S2210: When it is detected that a person is pressing the housing, the air pressure value in the ear canal detected by the pressure sensor is obtained.

[0074] In this step S2210, a pressure sensor that can detect the air pressure of the feedback microphone in real time is built in the front sound outlet of the earphone, and the pressure sensor is used to obtain the air pressure in the ear canal. Here, in this step S2210, when it is detected that a human hand presses the shell, obtaining the air pressure value in the ear canal detected by the pressure sensor can further include: when it is detected that a human hand presses the shell, turning on the pressure sensor; when the pressure sensor is in the turned-on state, obtaining the air pressure value in the ear canal detected by the pressure sensor.

[0075] It is understandable that when a normal in-ear active noise reduction headset is worn, the headset, ear canal, and eardrum form a closed cavity. When the infrared sensor on the headset shell detects that a hand touches the headset shell, it activates the pressure sensor inside the headset and starts monitoring the pressure inside the ear canal to obtain the air pressure value in the ear canal.

[0076] Step S2220: When the air pressure value in the ear canal exceeds a preset pressure threshold, the feedback noise reduction intensity of the earphone is reduced or the feedback noise reduction function of the earphone is turned off to prevent the earphone from generating howling.

[0077] The preset pressure threshold may be a value set according to actual application scenarios and actual needs, and this embodiment does not limit this.

[0078] In this step S2220, when the air pressure value in the ear canal exceeds the preset pressure threshold, reducing the feedback noise reduction strength of the earphone or turning off the feedback noise reduction function of the earphone to prevent the earphone from generating howling can further include: when the air pressure value in the ear canal exceeds the preset pressure threshold, obtaining the deviation between the air pressure value in the ear canal and the preset pressure threshold; when the deviation is within a first deviation range, reducing the feedback noise reduction strength of the earphone to prevent the earphone from generating howling; when the deviation is within a second deviation range, turning off the feedback noise reduction function of the earphone to prevent the earphone from generating howling.

[0079] Since the cavity inside the ear canal and the earphone earplug form a closed cavity, the internal pressure value is basically constant. When a person presses the earphone hard, the air pressure in the internal cavity will suddenly rise. Based on this, the earphone stores a preset pressure threshold. When the pressure sensor detects that the pressure value inside the ear canal rises instantly and exceeds the preset pressure threshold, the pressure sensor transmits the information of the instantaneous increase in air pressure to the chip inside the earphone.

[0080] On the one hand, the chip inside the earphone calculates the deviation between the air pressure value in the ear canal and the preset pressure threshold, and when the deviation is within the first deviation range, the chip inside the earphone controls the noise reduction module to reduce the feedback noise reduction strength. The greater the deviation, the more the feedback noise reduction strength of the noise reduction module is reduced.

[0081] On the other hand, the chip inside the earphone calculates the deviation between the air pressure value in the ear canal and the preset pressure threshold, and directly turns off the feedback noise reduction function of the earphone when the deviation is within the second deviation range, for example, the chip inside the earphone controls the noise reduction module to be in a dormant state. It is understandable that when the deviation is within the second deviation range, it usually indicates that the air pressure value in the ear canal is very large, and in this case, the feedback noise reduction function of the earphone can be directly turned off.

[0082] According to the above steps S2210 to S2220, a pressure sensor is used to monitor the air pressure in the ear canal cavity in real time. By monitoring the instantaneous pressure inside the ear canal, the feedback noise reduction intensity is adjusted in real time or the feedback noise reduction function is directly turned off, thereby preventing the user from suddenly pressing the earphones, causing excessive feedback noise reduction intensity and causing howling problems.

[0083] According to this embodiment, when wearing headphones, it is possible to detect whether there is a human hand pressing the headphone shell through the infrared sensor on the headphone shell, and when it is detected that there is a human hand pressing the headphone shell, the noise reduction intensity of the headphones will be reduced or the noise reduction function of the headphones will be turned off, so as to prevent the user from suddenly pressing the headphones, causing the feedback noise reduction intensity of the headphones to be too high, resulting in howling problems.

[0084] <Example>

[0085] Next, an example of a method for controlling headphones is shown. In this example, the headphones are in-ear active noise reduction headphones. Figure 3 As shown, the control method of the headset includes:

[0086] Step S301, when wearing the earphone, detect whether there is any obstruction on the earphone housing through the infrared light sensor. If there is an obstruction, execute step S302, otherwise, execute step 306.

[0087] Step S302: When it is detected that there is an obstruction on the housing, the temperature of the obstruction is detected by an infrared temperature sensor.

[0088] Step S303, determining whether the detected temperature of the obstruction matches the temperature of a human hand, if yes, executing step S304, otherwise, executing step S306.

[0089] Step S304: when the detected temperature of the shielding object matches the temperature of a human hand, turn on the pressure sensor.

[0090] Step S305, detect the pressure value in the user's ear canal through the pressure sensor, and when the detected pressure value exceeds the preset pressure threshold, reduce the feedback noise reduction intensity of the earphone or turn off the feedback noise reduction function of the earphone to prevent the earphone from generating howling, and the process ends.

[0091] Step S306, turn off the pressure sensor and the process ends.

[0092] According to this example, two progressive infrared sensors are used on the earphone to determine whether a hand touches the earphone shell. At the same time, a pressure sensor is used to monitor the air pressure in the ear canal cavity in real time. By monitoring the instantaneous pressure in the ear canal and adjusting the feedback noise reduction intensity in real time, it is possible to prevent the user from suddenly pressing the earphone, causing the feedback noise reduction intensity to be too high, resulting in howling problems.
