step S20, determining the number of microphones according to the current noise reduction mode, wherein the number of microphones corresponding to different noise reduction modes is different;
and step S30, controlling the microphones corresponding to the number of the microphones to collect the environmental noise so as to reduce the noise according to the environmental noise collected by the microphones corresponding to the number of the microphones.
The noise reduction method of the earphone is used for controlling noise reduction of the earphone, and the earphone serving as a portable sound box is easily influenced by the ambient noise of people. In order to prevent the environmental noise from affecting the using effect of the earphone, the earphone is provided with the sounder, and the sounder is used for emitting reverse waves of the environmental noise so as to offset or partially offset the environmental noise.
In the embodiment, the earphone is set with a noise reduction mode and a non-noise reduction mode, and a user can select the noise reduction mode or the non-noise reduction mode; the earphone can also determine whether to enter a noise reduction mode according to the environmental noise, if the environmental noise is greater than a preset threshold value, the earphone is judged to enter the noise reduction mode, and the earphone actively enters the noise reduction mode; or when the earphone is set to be in a wearing state, the noise reduction mode is judged to be entered, and the noise reduction mode is actively entered. This embodiment detects human infrared signal through set up infrared sensor in the earphone, and when the earphone was mated to the user's ear, infrared sensor detected the infrared signal of human feedback, and the infrared signal threshold value is predetermine in the setting, and the infrared signal that infrared sensor detected is in the infrared signal default value then judges that the earphone is in the wearing state, and the infrared signal that detects as infrared sensor is not in the infrared signal default threshold value then judges that the earphone is not in the wearing state.
The earphone in practical application, need have multiple functions just can satisfy user's various demands, for example to falling the noise, the different occasions are different to the noise reduction effect's of earphone demand, if in the office, under the more quiet environment such as classroom, ambient noise is little, little to the influence of earphone, the general noise reduction mode of noise reduction of user's demand noise reduction effect falls this moment, can avoid the long-time high frequency of earphone to fall to bring loss of power consumption on the one hand, on the other hand can also prevent to take behind the earphone in the office or classroom can't communicate with others and exchange. If dangerous environment such as road again, ambient noise is great, and it is big to earphone use influence, and the function demand of making an uproar is fallen to the high, but dangerous environment adopts when falling the too high mode of making an uproar of falling the function of making an uproar, and the user is difficult to hear the warning sound of whistling on the road, causes the incident danger easily. Or, in the noisy and not dangerous environment such as subway, public transit, ambient noise is great, and it is big to use the influence to the earphone, and the function demand of making an uproar is fallen to the noise reduction function demand height, adopts the general noise reduction mode of the effect of making an uproar of falling the noise at this moment, can't satisfy user's user demand, consequently needs the noise reduction effect of preferred.
In order to meet different requirements of a user on noise reduction effects of the headset in different use scenes, the noise reduction mode is set to comprise one or more of a quiet environment noise reduction mode, a dangerous environment noise reduction mode and a noisy environment noise reduction mode. Different noise reduction mode correspondences have different noise reduction effects, the noise reduction effect of the quiet environment noise reduction mode is general, the noise reduction effect of the dangerous environment noise reduction mode is poor, and the noise reduction effect of the noisy environment noise reduction mode is high.
This embodiment adopts the mode of making an uproar to fall, it offsets or partly offsets the mode of noise and realizes making an uproar to fall through generating the reverse wave based on making an uproar to fall initiatively, and the reverse wave that generates can offset the noise completely or can only offset partial noise is based on the environmental noise size of gathering, so this embodiment sets up the environmental noise difference of gathering under the different modes, realize different noise reduction, it is different specifically through setting up the microphone quantity that is used for gathering the noise that corresponds under the different modes, realize the variation in size of the environmental noise who gathers. If under dangerous ambient noise mode, when in order to be applicable to the user and listen the song, ensure to hear whistle warning sound safely, choose for use less or a microphone to collect ambient noise, less or the ambient noise that a microphone was gathered is less, and the initiative is fallen and is fallen noise and offset less ambient noise, and then ensures that the user can hear warning sound, takes precautions against the incident. If in the quiet environment noise reduction mode, because the ambient noise is small, the ambient noise can be collected by two or more microphones (two microphones can be used to reduce the power consumption), so that the power consumption is reduced while the noise reduction effect is ensured. If under noisy environment noise reduction mode, ambient noise is great, adopts three or three above microphones to gather ambient noise, and the pickup mouth orientation of each microphone is different, and the ambient noise of gathering is great and more meticulous, based on ambient noise, active noise reduction offsets more ambient noise, so ensures the syllable-dividing effect of earphone. The number of the microphones corresponding to each mode is not limited to 1, 2 or 3, and the number of the microphones corresponding to the noise reduction mode in the hazardous environment is less than the number of the microphones corresponding to the noise reduction mode in the quiet environment, and the number of the microphones corresponding to the noise reduction mode in the quiet environment is less than the number of the microphones corresponding to the noise reduction mode in the noisy environment.
The earphone is provided with a plurality of microphones, and under different noise reduction modes, the environment noise collected under different modes is different by controlling the opening or closing of the microphones with different numbers.
Further, the noise reduction method of the embodiment further includes: and step S40, controlling the sounder to generate sound waves with the same frequency and the opposite direction of the environmental noise according to the environmental noise.
The sound generator is arranged in the earphone, and when the processor receives the environmental noise collected by the microphone, sound waves are generated according to the environmental noise so as to counteract or partially counteract the environmental noise by the sound waves. The number of the microphones for acquiring the environmental noise corresponding to different noise reduction modes is different, and the environmental noise acquired by the microphones with different numbers is different, for example, when the number of the microphones for acquiring the environmental noise is more, the acquired environmental noise is more and finer; if the number of microphones for collecting the environmental noise is small, the collected environmental noise is small. The reverse wave generated by the sounder is used for offsetting the acquired environmental noise, and if the acquired environmental noise is more, the offset environmental noise is more, and the noise reduction effect is better; if the acquired environment noise is less, the offset environment noise is less, and the noise reduction effect is poorer.
This embodiment is through setting up multiple noise reduction mode, and the mode correspondence of making an uproar is fallen to the difference adopts the microphone of different quantity to carry out the noise collection, when obtaining current noise reduction mode, and the control current noise reduction mode corresponds the microphone of quantity and carries out ambient noise collection to make the earphone according the environmental operation is fallen and is fallen the noise, because the microphone quantity that different modes correspond is different, and its noise reduction effect is different, falls the mode and uses different scenes with the difference, satisfies the user and falls the requirement of making an uproar to the earphone difference in different scenes, falls the function diversification of making an uproar, and the suitability is strong.
Referring to fig. 4, the present invention further provides another embodiment of a noise reduction method for a headphone based on the foregoing embodiment, where the noise reduction method for a headphone further includes:
step S50, when the noise reduction mode switching operation is detected, determining a target noise reduction mode according to the current noise reduction mode;
step S60, broadcasting the voice information of the target noise reduction mode;
based on the above embodiments, in this embodiment, since the earphone has multiple noise reduction modes, corresponding noise reduction modes can be selected according to different scenes, when a noise reduction mode switching operation is detected, a target noise reduction mode is determined according to a current noise reduction mode, and after the target noise reduction mode is determined, voice information of the target noise reduction mode is broadcasted in a voice broadcasting manner, if the current noise reduction mode is a quiet environment noise reduction mode, a noise reduction mode switching operation is detected and the target noise reduction mode is determined to be a dangerous environment noise reduction mode, a "dangerous environment noise reduction mode" is broadcasted, a user can determine whether to select to switch to the target noise reduction mode based on the broadcasted voice information, if the user receives confirmation information of the target noise reduction mode, the current noise reduction mode is switched to the target noise reduction mode, and if the confirmation information of the target noise reduction mode is not received, and when the noise reduction mode switching operation is received again, determining the target noise reduction mode, and further determining whether to select the target noise reduction mode.
The earphone is a touch earphone, the noise reduction mode is switched by adopting a touch mode or a knocking mode, if a gravity sensor is arranged in a shell of the earphone, a user triggers a switching instruction by touching or knocking the earphone, and if a terminal receives a signal detected by the gravity sensor for a second preset number of times, the noise reduction mode switching operation is determined to be detected. The second preset number of times may be 2, for example, when the user double-clicks the earphone, the Y axis of the gravity sensor changes due to the knocking force, at this time, the gravity sensor sends a detection signal to the processor, and the processor determines that the noise reduction mode switching operation is detected after receiving the signals sent by the gravity sensor twice. The touch or knock type noise reduction mode is adopted, especially the double-click type noise reduction mode is adopted to trigger, and the condition of mistaken touch can be effectively avoided.
In other embodiments, the noise reduction mode switching operation may also be triggered by voice information, for example, when the terminal receives the noise reduction mode switching voice information, it is determined that the noise reduction mode switching operation is detected. The earphone is provided with a normally open microphone for collecting voice control instructions, when a user sends the voice control instructions, keywords corresponding to the voice control instructions are obtained, whether the control instructions correspond to noise reduction mode switching operation or not is determined based on the keywords, if yes, the noise reduction mode switching operation is judged to be detected, and the noise reduction mode switching is carried out by the terminal. The voice control noise reduction mode is switched, and the control is convenient for a user compared with a touch type or a knocking type.
Further, referring to fig. 5, the step of determining a target noise reduction mode according to the current noise reduction mode includes:
step S51, acquiring a preset noise reduction mode sequence;
and step S52, determining a target noise reduction mode according to the current noise reduction mode and the preset noise reduction mode sequence.
The method comprises the steps that noise reduction modes are set and arranged according to a preset sequence, when the noise reduction modes are switched, the target noise reduction modes are determined according to the current noise reduction modes and the preset noise reduction mode sequence, if the quiet environment noise reduction modes, the dangerous environment noise reduction modes and the noisy environment noise reduction modes are sequentially sequenced, when the quiet environment noise reduction modes are the current noise reduction modes, the noise reduction mode switching operation is detected, the target noise reduction modes are the dangerous environment noise reduction modes, and if the noise reduction mode switching operation is detected twice, the target noise reduction modes are the noisy environment noise reduction modes.
In other embodiments, the noise reduction mode may be switched to be successively decreased or successively increased, for example, the step of determining the target noise reduction mode according to the current noise reduction mode may include: determining the noise reduction capability of the current noise reduction mode according to the current noise reduction mode; determining a noise reduction mode with lower or higher noise reduction capability according to the noise reduction capability; and determining a target noise reduction mode according to the noise reduction mode with lower or higher noise reduction capability. According to the mode switching that the mode of making an uproar is reduced in proper order or strengthens in proper order, the user can be based on the mode of making an uproar and confirm the mode of making an uproar is made an uproar to the target, can exempt from the step of broadcast voice broadcast target mode of making an uproar, reduces the loaded down with trivial details of process.
Step S70, when receiving the confirmation information of the target noise reduction mode, switching the current noise reduction mode to the target noise reduction mode, and executing the step of obtaining the current noise reduction mode.
Specifically, after the target noise reduction mode is determined, when a signal detected by the gravity sensor for a first preset number of times is received within a preset time interval, it is determined that the confirmation information of the target noise reduction mode is received. The first preset number of times may be set to 1, and the number of times of the first preset number of times is different from that of the second preset number of times, so as to avoid that the terminal cannot determine whether the detected signal is the confirmation information of the noise reduction mode switching operation or the target noise reduction mode.
After a terminal determines a target noise reduction mode, voice information of the target noise reduction mode is broadcasted, a user knows the target noise reduction mode based on the voice information and further determines whether to enter the target noise reduction mode, and when the user determines to enter the target noise reduction mode, the user determines to enter the target noise reduction mode through a single touch or a single earphone knocking mode.
In other embodiments, after the target noise reduction mode is determined, when the confirmation voice information is received, it is determined that the confirmation information of the target noise reduction mode is received. That is, after the user receives the voice message broadcasting the target noise reduction mode, if the user determines to enter the target noise reduction mode, the user can send a voice control instruction to control the terminal to enter the target noise reduction mode.
It can be understood that, when the confirmation information of the target noise reduction mode is not received within the preset time interval, the terminal continues to reduce noise in the current noise reduction mode until the noise reduction mode switching operation is to be started again, and then executes the step of determining the target noise reduction mode according to the current noise reduction mode. If the user accidentally triggers the target noise reduction mode, the possibility of sending the knocking operation again in the preset time interval is low, and the noise reduction mode is continued in the current noise reduction mode when the confirmation information of the target noise reduction mode is not received in the preset time interval, so that the situation that the noise reduction mode is switched when the user accidentally touches the noise reduction mode can be avoided.
According to the embodiment, the multiple noise reduction modes can be flexibly switched, the noise reduction modes can be randomly selected based on the requirements of users in different scenes, and the operation is simple and convenient.
In still another embodiment, referring to fig. 6, the noise reduction method of the headphone further includes:
step S50, when the noise reduction mode switching operation is detected, determining a target noise reduction mode according to the current noise reduction mode;
step S60, broadcasting the voice information of the target noise reduction mode;
step S80, when detecting that there is no noise reduction mode switching operation within a preset time interval, switching the current noise reduction mode to the target noise reduction mode, and executing the step of acquiring the current noise reduction mode.
Compared with the embodiment shown in fig. 4, the difference of this embodiment is that after determining a target noise reduction mode and broadcasting the voice information of the target noise reduction mode, when a user determines to enter the target noise reduction mode, the user may confirm to perform noise reduction by using the target noise reduction mode in a manner of stopping touching or tapping an earphone. And after the terminal sets the switching operation of the detection noise reduction mode, presetting a time interval as the confirmation time, and if the switching operation of the noise reduction mode is not performed within the preset time interval, determining that the user defaults to adopt the target noise reduction mode for noise reduction.
In the embodiment, when no noise reduction mode switching operation is detected within a preset time interval, the noise reduction mode is switched in a mode of switching the current noise reduction mode into the target noise reduction mode, so that manual operation processes of a user are reduced, and the method is convenient to use.
