     DETAILED DESCRIPTION 
     The technical solutions in embodiments of the present disclosure are described below clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are some rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure. 
     Before the receiver control method and device according to the embodiments of the present disclosure are proposed, the inventor of the present disclosure has performed in-depth study on the habits of users using electronic devices such as a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device and a pedometer for call. It has been found from the study that most of the time, a user is not stationary when holding the electronic device for call, and the hand or head may move during the call, so that the user&#39;s auricle will move relative to the micro-slit in the receive structure of the electronic device, the blockage situation of the user&#39;s auricle on the micro-slit is changed, and the blockage situation of the sound output holes of the receiver at different positions of the micro-slit will change accordingly, thereby leading to unsmooth air flow in the cavity of the receiver, easily generating noise and influencing the call process. 
     Therefore, the inventor of the present disclosure has further performed in-depth study on the working processes when the receiver is not blocked and when the receiver is blocked. On this basis, the receiver control method and device according to the embodiments of the present disclosure are provided, so as to reduce the noise caused by improper use of the electronic device, for example the sound output hole of the receiver is blocked. 
     The receiver control method and device provided by the embodiments of the present disclosure are applied to an electronic device including at least one receiver, wherein the at least one receiver is electrically connected to a baseband circuit, and a feedback circuit is arranged between the at least one receiver and the baseband circuit. When the number of the at least one receiver is two or more than two, each receiver is electrically connected to the baseband circuit respectively, and a feedback circuit is arranged between each receiver and the baseband circuit respectively. 
       FIG. 1  is a flow block diagram of an embodiment of a receiver control method according to the present disclosure. As shown in  FIG. 1 , the receiver control method includes: 
     S 102 : detecting at least one receiver; and 
     S 104 : in a case of detecting that a first receiver of the at least one receiver is blocked, adjusting the electrical signal gain of the feedback circuit corresponding to the first receiver so as to reduce an electrical signal input to the first receiver. 
     The receiver control method provided by the embodiment of the present disclosure may be applied to the electronic device including at least one receiver. The electronic device may include a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a vehicle-mounted terminal, a wearable device, a pedometer, or the like. 
     In the embodiments of the present disclosure, the situation that a sound output hole of the receiver is blocked can be detected. In a case of detecting that the first receiver of the at least one receiver is blocked, self-adaptive adjustment may be realized in combination with the feedback circuit corresponding to the first receiver, the electrical signal gain of the feedback circuit corresponding to the first receiver is adjusted, and the electrical signal input to the first receiver is reduced, so that noise generated by the hole blockage of the first receiver is suppressed, the call experience of a user is improved, noise caused by unsmooth airflow in a cavity of the receiver due to the hole blockage of the receiver is obviously reduced, and the effect for a user who needs to move the electronic device frequently during the call is improved significantly. 
     In the step S 102  of some embodiments of the present disclosure, the method for detecting the at least one receiver may specifically include: detecting a target parameter of the at least one receiver electrically connected to the baseband circuit to obtain a detection value of the target parameter, wherein the target parameter includes an impedance of the receiver and/or a resonance frequency of the receiver. 
     In the step S 104  of some embodiments of the present disclosure, the method for specifically determining whether the first receiver of the at least one receiver is blocked may include: in a case that the detection value of the target parameter of the first receiver of the at least one receiver meets a preset condition, determining that the first receiver is blocked, that is, hole block occurs in the first receiver. That the receiver is blocked may be that the sound output hole of the receiver is blocked. At this time, the electrical signal gain of the feedback circuit corresponding to the first receiver may be adjusted so as to reduce the electrical signal input to the first receiver. 
     In some embodiments of the present disclosure, after the step S 104 , the receiver control method may further include: 
     in a case of detecting that the first receiver is not blocked, adjusting the electrical signal gain of the feedback circuit corresponding to the first receiver so as to increase the electrical signal input to the first receiver to a preset value, 
     wherein the preset value refers to a gain value when the gain of the electrical signal of the feedback circuit corresponding to the first receiver is at an initial level. 
     Therefore, the embodiment of the present disclosure may detect a receiving signal of the receiver and adjust the electrical signal gain of the feedback circuit of the receiver meeting the determination condition of the hole block of the receiver, so as to adjust the magnitude of the electrical signal input to the receiver, for example, to reduce the voltage of the electrical signal, thereby suppressing noise generated by hole blockage of the receiver. 
       FIG. 2  is a flow block diagram of another embodiment of a receiver control method according to the present disclosure. As shown in  FIG. 2 , the processing process of the receiver control method is as follows: 
     S 202 : in the process that the electronic device outputs a sound through at least one receiver, the baseband circuit outputs a signal, such as an audio electrical signal; 
     S 204 : the receiver receives the audio electrical signal; 
     in application, the audio electrical signal output by the baseband circuit needs to be processed by an audio codec, a power amplifier and the like before entering the receiver, and the receiver converts the received audio electrical signal into a sound signal to make a sound through a micro-slit in the receiver structure; 
     S 206 : in the working process of the receiver, a working parameter of the receiver is detected to mainly obtain a detection value of a target parameter; 
     S 208 : determining whether there is a receiver of the at least one receiver is blocked on the basis of the detection value of the target parameter, that is, whether there is a receiver suffering from hole blockage; 
     in a case that the detection value of the target parameter of the first receiver of the at least one receiver meets the preset condition, considering that the sound output hole of the first receiver is blocked, that is, there is a blocked receiver, and performing S 210 ; 
     in a case that the detection value of the target parameter of the at least one receiver does not meet the preset condition, it indicates that the sound output holes of all the receivers are not blocked, that is, there is no blocked receiver, returning to S 206  and continuously detecting the working parameter of the receiver; 
     S 210 : starting the gain adjustment on the electrical signal of the feedback circuit corresponding to the first receiver, that is, reducing the gain of the electrical signal of the feedback circuit so as to reduce the electrical signal input to the first receiver, thereby reducing the sound output volume of the first receiver and reducing noise; or adjusting the gain of the electrical signal of the feedback circuit to zero to reduce the voltage of the electrical signal input to the first receiver to zero, so that the first receiver stops work and the aim of eliminating noise can be achieved; and 
     then, when the working parameter of the first receiver is restored to normal, that is, when the detection value of the target parameter of the first receiver does not meet the preset condition any more, the gain of the electrical signal of the feedback circuit corresponding to the first receiver may be increased to the initial level, and normal sound is made. 
     In some embodiments of the present disclosure, the target parameter may be an impedance of the receiver, and before the step of detecting the at least one receiver, the receiver control method may further include: 
     detecting a maximum impedance R′ in a case that each receiver is not blocked, detecting a maximum impedance value R″ in a case that each receiver is blocked, and setting the preset condition as: the detected maximum impedance value of the receiver is less than a first predetermined threshold, wherein the specific value of the R′ may be detected before the receiver leaves the factory. 
     Specifically, in a case that the target parameter is the impedance of the receiver, the corresponding preset condition may be specifically: the detected maximum impedance value of the receiver is less than the first predetermined threshold. 
     In some embodiments, the first predetermined threshold may be the maximum impedance value R′. The reason for such setting is that the study shows that an impedance peak value R″ after hole blockage of the receiver is less than an impedance peak value R′ when the receiver is not blocked, so when it is detected that the impedance peak value of the receiver is less than the impedance peak value R′ which should be in normal operation, it may be determined that the sound output hole of the receiver has been blocked. 
     In some other embodiments, the first predetermined threshold may be (R′+R2″)/2. The advantage of such setting is that the first predetermined threshold, that is, the impedance threshold, is set as (R′+R2″)/2, which is between the peak value R′ when the receiver is not blocked and the peak value R2″ after hole blockage, and the requirement of determining hole blockage of the receiver is increased, so that the circuit will not be adjusted frequently due to the reduced impedance value caused by other factors in practical application. 
     In some other embodiments of the present disclosure, the target parameter may also be a resonance frequency of the receiver; and before the step of detecting the at least one receiver, the receiver control method may further include: 
     detecting a resonance frequency value F 0 ′ corresponding to the maximum impedance value R′ in a case that each receiver is not blocked, detecting a resonance frequency value F 0 ″ corresponding to the maximum impedance value R″ in a case that each receiver is blocked, and setting the preset condition as: the detected resonance frequency value corresponding to the maximum impedance value of the receiver is less than a second predetermined threshold, wherein the specific value of the F 0 ′ may be detected before the receiver leaves the factory. 
     Specifically, in a case that the target parameter is the resonance frequency of the receiver, the corresponding preset condition may be specifically: the detected resonance frequency value corresponding to the maximum impedance value of the receiver is less than the second predetermined threshold. 
     In some embodiments, the second predetermined threshold may be the resonance frequency value F 0 ′ corresponding to the maximum impedance value R′. The reason for such setting is that the study shows that the resonance frequency value F 0 ″ corresponding to the maximum impedance value R″ after hole blockage of the receiver is less than the resonance frequency value F 0 ′ corresponding to the maximum impedance value R′ when the receiver is not blocked, so when it is detected that the resonance frequency value corresponding to the maximum impedance value of the receiver is less than the resonance frequency value F 0 ″ which should be in normal operation, it may be determined that the sound output hole of the receiver has been blocked. 
     In some other embodiments, the second predetermined threshold may be (F 0 ′+F 0 ″)/2. The advantage of such setting is that the second predetermined threshold, that is, the impedance threshold, is set as (F 0 ′+F 0 ″)/2, which is between F 0 ′ when the receiver is not blocked and F 0 ″ after hole blockage, and the requirement of determining hole blockage of the receiver is increased, so that the circuit will not be adjusted frequently due to the reduced resonance frequency value caused by other factors in practical application. 
     In other implementation manners of the present disclosure, the target parameter may also be an impedance and a resonance frequency of the receiver. Before the step of detecting the at least one receiver, the receiver control method further includes: 
     making a first impedance curve f′ in a case that each receiver is not blocked, determining a maximum impedance value R1′ and a second maximum impedance value R2′ on the first impedance curve. After the detection value of the target parameter is obtained, the receiver control method further includes: based on the detection value of the target parameter, making a second impedance curve f″ of the receiver, and determining a maximum impedance value R1″ and a second impedance value R2″ on the second impedance curve, wherein the preset condition may be: on the f′ and the f″, a resonance peak of R1″ corresponds to a resonance peak of R1′, and a resonance peak of R2″ does not correspond to a resonance peak of R2′. 
     Specifically, the target parameters in the embodiments of the present disclosure are the impedance and the resonance frequency of the receiver. The impedance curve of the receiver may be made according to the evolution of the impedance and the resonance frequency.  FIG. 3  shows an effect schematic diagram of an impedance curve f′ when the receiver is not blocked and an impedance curve f″ after hole blockage of the receiver according to the embodiments of the present disclosure, wherein the x-coordinate is the resonance frequency F 0  of the receiver in hertz (Hz), and the y-coordinate is the impedance of the receiver in ohm (Ω). In  FIG. 3 , it also schematically marks the coordinates (F 01 ′, R 1 ′) of the maximum peak value point on the impedance curve f′ when the receiver is not blocked, and the coordinates (F 01 ″, R 1 ″) of the maximum peak value point and the coordinates (F 02 ″, R 2 ″) of the second maximum peak value point on the impedance curve f″ after hole blockage. 
     It can be seen from  FIG. 3  that through comparison after hole blockage of the receiver and when the receiver is not blocked: 
     firstly, the maximum impedance value R 1 ″ of the impedance curve f″ after hole blockage is reduced compared with the maximum impedance peak value R 1 ′ when the receiver is not blocked; 
     secondly, the maximum resonance peak of the impedance curve f″ after hole block corresponds to the maximum resonance peak of the impedance curve f′ when the receiver is not blocked, and the maximum resonance peak after hole blockage shifts to the left and the resonance frequency is reduced; and 
     thirdly, a resonance peak, that is, a resonance peak corresponding to the coordinates (F 02 ″, R 2 ″), of a second peak value occurs near a specific frequency, about between 2 k and 3 kHz in  FIG. 3 , it is found through comparison that the second maximum resonance peak of f″ after hole blockage does not correspond to the second maximum resonance peak of f′ when the receiver is not blocked, specifically as follows: a resonance peak corresponding to the second maximum resonance peak of f″ is not present on f′, but the curve is a smooth transition between 2 k and 3 k Hz on f′. 
     Based on this, the embodiments of the present disclosure may set the preset condition as: on f′ and f″, the resonance peak of R 1 ′ corresponds to the resonance peak of R 2 ′, and the resonance peak of R 2 ′ does not correspond to the resonance peak of R 2 ″. In a case that the working process of the receiver meets the preset condition, it may be considered that hole blockage occurs in the receiver. 
     The above describes the detection values of the target parameters adopted in various implementation manners of the embodiments of the present disclosure and the corresponding preset conditions. Whether the receiver is blocked is detected in real time. If the preset condition is met, the gain adjustment on the receiver is started in order to avoid noise caused by hole blockage of the receiver, specifically as follows: the gain is increased or reduced through the feedback circuit of the receiver, so that the electrical signal input to the receiver is reduced, and the noise caused by hole blockage can be reduced to a certain degree. 
     In other embodiments, the electrical signal input to the receiver may also be adjusted to zero, so that the receiver stops working; and after the hole blockage situation of the receiver is eliminated, the gain is restored to the initial level. 
     Corresponding to the receiver control method, the embodiments of the present disclosure further provide a receiver control device.

     In some other embodiments of the present disclosure, the target parameter includes the impedance and the resonance frequency of the receiver. The receiver control device  300  further includes:
