Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The following describes in detail the volume control method of the dual-diaphragm speaker provided by the embodiment of the application through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1, an embodiment of the present application provides a method for controlling volume of a dual-diaphragm speaker, where the method includes:
step 101, obtaining state parameter values of a first diaphragm and a second diaphragm in a dual-diaphragm loudspeaker; the first vibrating diaphragm and the second vibrating diaphragm respectively produce sound at different positions of the electronic equipment.
In the embodiment of the application, the double-diaphragm loudspeaker can comprise a first diaphragm and a second diaphragm, wherein the double-diaphragm loudspeaker can simultaneously work for the first diaphragm and the second diaphragm to emit two paths of different sound waves, or only the first diaphragm or only the second diaphragm works to emit one path of sound waves. For example, a first diaphragm of a dual-diaphragm speaker may be a speaker that sounds on the front of an electronic device, and a second diaphragm of the dual-diaphragm speaker may be a speaker that sounds on the back or top of the electronic device.
Under different use scenes, the mode of sound production of two vibrating diaphragm speakers is different, for example, in the earphone mode, in order to avoid leaking sound, two vibrating diaphragm speakers can sound production simultaneously for first vibrating diaphragm and second vibrating diaphragm, first vibrating diaphragm is the front sound production of electronic equipment, sound orientation user's ear direction, the second vibrating diaphragm is the back or top sound production at electronic equipment for offset the sound that first vibrating diaphragm sent, avoid being in around the electronic equipment to hear the sound that the speaker sent, that is to say, the user actually heard is the sound after two vibrating diaphragm synthesis, if one of them vibrating diaphragm is bad, the sound that the user heard is that single one vibrating diaphragm sent, the sound that leads to the user actually to hear is different from the sound that two vibrating diaphragms of two vibrating diaphragm speakers were all normal time synthesis. Therefore, the application firstly judges the working states of the first vibrating diaphragm and the second vibrating diaphragm by acquiring the state parameter values of the first vibrating diaphragm and the second vibrating diaphragm in the double-vibrating-diaphragm loudspeaker so as to correspondingly adjust how the other vibrating diaphragm which works normally adjusts the volume under the condition that the first vibrating diaphragm or the second vibrating diaphragm is broken, thereby balancing the sound emitted by the double-vibrating-diaphragm loudspeaker.
Optionally, the state parameter value includes an impedance value, and step 101 specifically includes:
a substep 1011, obtaining a first impedance value of the coil corresponding to the first diaphragm and a second impedance value of the coil corresponding to the second diaphragm; the first impedance value is detected by a first power amplifier connected with the first vibrating diaphragm, and the second impedance value is detected by a second power amplifier connected with the second vibrating diaphragm.
In the embodiment of the application, the intelligent power amplifier can be used for detecting the working state of the vibrating diaphragms in the double-vibrating-diaphragm loudspeaker, and each vibrating diaphragm in the double-vibrating-diaphragm loudspeaker is provided with the independent intelligent power amplifier connected with the vibrating diaphragm, so that the impedance value of the coil of each vibrating diaphragm in the double-vibrating-diaphragm loudspeaker can be detected through the intelligent power amplifier, and the working state of the vibrating diaphragm can be judged through the impedance value. The impedance of the dual-diaphragm speaker may include a direct current impedance, which refers to an impedance that is not affected by a current frequency, i.e., an impedance of a coil of each diaphragm. The impedance value of the coil may characterize the magnitude of the resistance and resistance of the coil to current flow. The larger the impedance value is, the more difficult the current passes, the lower the output power of the intelligent power amplifier connected with the diaphragm is, the smaller the impedance value is, the larger the current output by the voice coil is, and the larger the output power of the intelligent power amplifier connected with the diaphragm is. Therefore, when the first diaphragm and the second diaphragm are input with current with preset frequency, the magnitudes of the first impedance value and the second impedance value corresponding to the first diaphragm and the second diaphragm can be detected through the magnitudes of the output power of the power amplifier connected with the first diaphragm and the second diaphragm. According to the judgment of whether the detected impedance value is in the preset normal range, whether the first vibrating diaphragm and the second vibrating diaphragm have faults or not can be determined.
Referring to fig. 2, fig. 2 shows a schematic diagram of a connection between a dual-diaphragm speaker and a power amplifier. In the figure, an intelligent power amplifier 1 is connected with a first vibrating diaphragm, an intelligent power amplifier 2 is connected with a second vibrating diaphragm, and impedance values corresponding to the two vibrating diaphragms are detected through the intelligent power amplifier connected with each vibrating diaphragm independently.
Optionally, the state parameter value includes encoded information, and step 101 specifically includes:
in step 1012, the first diaphragm and the second diaphragm are encoded.
In the embodiment of the application, the microphone at the top of the electronic equipment can receive the sound emitted by the first vibrating diaphragm and the second vibrating diaphragm, so that the sound received by the microphone at the top can be used for detecting whether the two vibrating diaphragms have sound. In order to distinguish whether the sound received by the top microphone is coming from the first vibrating diaphragm or the second vibrating diaphragm, the two vibrating diaphragms can be respectively encoded, the vibrating diaphragms can be encoded, the voice signals sent by the vibrating diaphragms can be numbered, and when the voice signals are received, whether the two vibrating diaphragms work normally is determined through the encoding information of the voice signals.
Further, the voice signal sent by the dual-diaphragm loudspeaker is a signal with the frequency within 20KHz, so that ultrasonic waves can be used for encoding during encoding, for example: the codes may be 21.5KHz or 23KHz, and embodiments of the present application are not limited in this regard.
Optionally, the substep 1012 specifically includes:
and a substep 10121, respectively encoding the first diaphragm and the second diaphragm by using different frequency points to obtain first encoding information corresponding to the first diaphragm and second encoding information corresponding to the second diaphragm.
In the embodiment of the present application, the mode of detecting whether the working state of the diaphragm is normal may also be: the diaphragms are encoded in different frequency points, because the voice signal is a signal within 20KHz, ultrasonic waves are used for encoding, and 21.5K encoding can be adopted for the first diaphragm, namely, the first encoding information corresponding to the first diaphragm is 21.5KHz; the second vibrating diaphragm is encoded by 23KHz, namely the second encoding information corresponding to the second vibrating diaphragm is 23KHz; therefore, through different frequency points, after the received voice signals, the vibration film from which the voice signals come is determined according to whether the coding information corresponding to the voice signals is 21.5KHz or 23KHz, and then the working states of the two vibration films are determined.
Optionally, the substep 1012 specifically includes:
step 10122, encoding the first diaphragm and the second diaphragm with the same frequency point to obtain third encoded information corresponding to the first diaphragm and the second diaphragm, setting the sounding duration of the first diaphragm as a first time period, setting the sounding duration of the second diaphragm as a second time period, and sounding the first diaphragm and the second diaphragm at different time points.
In the embodiment of the application, the diaphragm can also be encoded in the same frequency point mode: for example, 22KHz is used to encode the diaphragms, so that the third encoded information corresponding to the first diaphragm and the second diaphragm is 22KHz. The frequency of the voice signals sent by the first vibrating diaphragm and the frequency of the voice signals sent by the second vibrating diaphragm are the same, so that the received voice signals are the signals sent by the first vibrating diaphragm or the signals sent by the second vibrating diaphragm, the duration of the voice signals sent by the first vibrating diaphragm and the second vibrating diaphragm can be set, and the voice signals sent by the first vibrating diaphragm and the second vibrating diaphragm are distinguished by setting different durations. And further determining the working states of the first vibrating diaphragm and the second vibrating diaphragm.
Referring to fig. 3, fig. 3 shows a signal transmission cycle chart in the same frequency point coding mode, wherein the abscissa indicates the duration of the voice signal, and 0.1s to 0.2s may be the duration of the voice signal of the first diaphragm, that is, the first time period may be 0.1s,0.2s to 0.4s may be the sounding duration of the voice signal of the second diaphragm, that is, the second time period may be 0.2s, and the two diaphragms alternately transmit the voice signal, and the alternating period is 0.5s. Thus, when analyzing the duration of the voice signal received by the top microphone, it is possible to determine whether the received voice signal is a signal from the first diaphragm or the second diaphragm.
Sub-step 1013, in the case of sounding the dual-diaphragm speaker, obtaining the encoded information of the voice signal emitted by the dual-diaphragm speaker.
In the embodiment of the application, under the condition that the double-diaphragm loudspeaker produces sound, the coding information of the voice signal sent by the double-diaphragm loudspeaker is obtained, and the received voice signal is judged from which diaphragm according to the coding information. For example, in the manner of encoding the first diaphragm and the second diaphragm by using different frequency points, it may be determined according to the encoding information of the received voice signal, from which diaphragm the voice signal comes, and in the manner of encoding the first diaphragm and the second diaphragm by using the same frequency points, it may be determined according to the duration of the received voice signal, from which diaphragm the received voice signal comes.
Step 102, determining respective working states of the first diaphragm and the second diaphragm according to respective state parameter values of the first diaphragm and the second diaphragm.
In the embodiment of the application, after the state parameter values corresponding to the first vibrating diaphragm and the second vibrating diaphragm are obtained, whether the first vibrating diaphragm and the second vibrating diaphragm work normally or not can be determined by comparing the state parameter values with the preset standard range. That is, if the state parameter value accords with the preset standard range, the working state of the diaphragm is indicated to be normal, and if the state parameter value does not accord with the preset standard range, the working state of the diaphragm is indicated to be fault.
Optionally, step 102 specifically includes:
substep 1021, determining whether the first impedance value and the second impedance value are within a predetermined range.
In the embodiment of the application, when the impedance value is judged, the preset range can be 8Ω±4Ω, and if the first impedance value and the second impedance value are within the preset range, the two diaphragms are indicated to normally sound. The size of the preset range can be set according to different speakers, and the embodiment of the present application is not limited herein.
Sub-step 1022, if the first impedance value is not within the preset range, the working state of the first diaphragm is a fault state.
And step 1023, if the second impedance value is not within the preset range, the working state of the second diaphragm is a fault state.
In the embodiment of the application, the first impedance value of the first vibrating diaphragm detected by the first power amplifier is compared with a preset range, if the first impedance value is within the preset range, the working state of the first vibrating diaphragm is indicated to be normal, and if the first impedance value is not within the preset range, the working state of the first vibrating diaphragm is indicated to be fault. And similarly, comparing the second impedance value of the second vibrating diaphragm detected by the second power amplifier with a preset range, if the second impedance value is within the preset range, indicating that the working state of the second vibrating diaphragm is normal, and if the second impedance value is not within the preset range, indicating that the working state of the second vibrating diaphragm is fault.
Optionally, step 102 specifically includes:
and step 1024, determining the working states of the first diaphragm and the second diaphragm according to the coding information corresponding to the first diaphragm and the second diaphragm.
In the embodiment of the application, besides using the impedance values corresponding to the first vibrating diaphragm and the second vibrating diaphragm to judge the working states of the first vibrating diaphragm and the second vibrating diaphragm, the working states of the first vibrating diaphragm and the second vibrating diaphragm can also be judged by adopting the coding information of the first vibrating diaphragm and the second vibrating diaphragm respectively. Reference is made to the descriptions of sub-step 10121 and sub-step 10122, which are not repeated here.
Optionally, the substep 1024 specifically includes:
sub-step 10241, if the voice signal sent by the dual-diaphragm speaker does not include the first coding information, the working state of the first diaphragm is a fault state;
in sub-step 10242, if the voice signal sent by the dual-diaphragm speaker does not include the second encoded information, the working state of the second diaphragm is a fault state.
In the embodiment of the application, if two diaphragms in the dual-diaphragm loudspeaker are encoded by adopting encoding modes of different frequency points, then voice signals respectively sent by the two diaphragms have different frequencies, if the first diaphragm and the second diaphragm produce sound at the same time, when the top microphone receives the voice signals, the encoding information of the voice signals is obtained through analysis of the voice signals, if the encoding information corresponding to the voice signals is first encoding information, the received voice signals are the voice signals sent by the first diaphragm, the working state of the first diaphragm is a normal state, and because the encoding information corresponding to the voice signals does not comprise second encoding information, the second diaphragm cannot normally send sound, and the state of the second diaphragm is a fault state. It should be noted that the first diaphragm and the second diaphragm may also be configured to sound separately at different time points, so that the working state of each diaphragm may also be determined by separately detecting the voice signal sent by each diaphragm.
Optionally, the substep 1024 specifically includes:
in sub-step 10243, in the case of sounding by the dual-diaphragm speaker, the respective working states of the first diaphragm or the second diaphragm are determined according to the duration of the voice signal in which the encoded information received in the preset period is the third encoded information.
In the embodiment of the application, if the coding modes of the two diaphragms of the dual-diaphragm loudspeaker are the coding modes of the same frequency point, the working states of the two diaphragms can be determined by collecting the voice signals in a preset time period and analyzing the duration time of the voice signals in the preset period.
Specifically, during detection, the voice signal can be subjected to filtering processing firstly, so that the voice signal only comprises the voice signal of the third coding information, namely, the voice signal of 22KHz is reserved through the filtering processing, and the interference of other frequency point signals on the result is avoided; specifically, the duration of the voice signal may be determined by dBFS (Decibels Full Scale, full decibel scale) of the voice signal. For example, the judgment condition may be set to be greater than-40 dBus, the duration of which is recorded if the voice signal is greater than-40 dBus, and not recorded if the voice signal is less than-40 dBus. Specific judgment conditions can be designed according to the actual electronic structure of the loudspeaker, and the embodiment of the application is not limited herein.
Optionally, the substep 10243 specifically includes:
a substep A1, if the duration of the received voice signal is a first time period within a preset period, determining that the working state of the second diaphragm is a fault state;
a substep A2, determining that the working state of the first diaphragm is a fault state if the duration of the received voice signal is a second time period;
and a substep A3, wherein if the duration of the received voice signal is the sum of the first time period and the second time period, the working states of the first diaphragm and the second diaphragm are normal states.
In the embodiment of the application, the working states corresponding to the two diaphragms can be judged by counting the duration of the voice signal in the preset time period. Statistics of the duration of the signal may be recorded by a timer.
Referring to fig. 3, voice signals within 500ms may be collected for analysis. If the duration of the received voice signal is within 10mS of 100mS, the voice signal received within 500mS is the voice signal sent by the first diaphragm, which indicates that the second diaphragm fails to normally sound and the second diaphragm fails because the sound-producing time points of the first diaphragm and the second diaphragm are different. If the duration of the received voice signal is within 200mS plus or minus 10mS within the period, the received voice signal is the voice signal sent by the second diaphragm within 500mS, which indicates that the first diaphragm fails to normally sound and the first diaphragm fails. If the duration of the received voice signal is within 300mS plus or minus 10mS within the period, the received voice signal is the voice signal commonly emitted by the first vibrating diaphragm and the second vibrating diaphragm within 500mS, which means that the first vibrating diaphragm and the second vibrating diaphragm normally emit sounds, that is, the working states of the first vibrating diaphragm and the second vibrating diaphragm are normal.
Step 103, adjusting the sound volume of the second diaphragm or the first diaphragm when the working state of the first diaphragm or the second diaphragm is a fault state. Optionally, the speaker or the receiver frequency response can be optimized to meet the user requirement according to the audio effect when both the receiver and the speaker work normally.
In the embodiment of the application, when the working state of the first diaphragm or the second diaphragm is a fault state, the volume of the other diaphragm can be properly adjusted according to the sounding mode of the current double-diaphragm loudspeaker so as to balance the volume of the sounding sound. For example, if two diaphragms are both sounding normally, the sound of the two diaphragms is higher than that of a single diaphragm, then the sound volume of the normal diaphragm can be properly adjusted to compensate for the sound of the fault diaphragm, if the two diaphragms are both sounding normally, the sound of the two diaphragms is lower than that of a single diaphragm, then the sound volume of the normal diaphragm can be properly reduced to avoid the sound volume of a single diaphragm being too high, which causes discomfort to the user.
Optionally, the first diaphragm is a diaphragm of a receiver, the second diaphragm is a diaphragm of a speaker, and step 103 specifically includes:
Sub-step 1031, when the first diaphragm and the second diaphragm are in the same phase, increasing the sound volume of the second diaphragm if the working state of the first diaphragm is a fault state, and increasing the sound volume of the first diaphragm if the working state of the second diaphragm is a fault state. And according to the audio frequency effect when the receiver and the loudspeaker work normally, the loudspeaker or the receiver frequency response is optimized to meet the user requirement.
In the embodiment of the application, the first vibrating diaphragm can be a vibrating diaphragm of a receiver, and the receiver is commonly used in a receiver mode, so that the first vibrating diaphragm is used for serving application scenes with high requirements for privacy such as small sound and the like, the sound-producing position of the first vibrating diaphragm can be the front face of the electronic equipment or the included angle between the front face and the top side face of the electronic equipment, the second vibrating diaphragm can be a vibrating diaphragm of a loudspeaker and is used for producing sound under different application scenes of the electronic equipment in cooperation with the first vibrating diaphragm, and the sound-producing position of the second vibrating diaphragm can be the top side face of the electronic equipment. In the privacy scene, the sound of the second vibrating diaphragm and the sound of the first vibrating diaphragm are matched to generate sound with the same vibration amplitude and opposite phases, so that a dipole sound source is formed, an anti-phase sound field superposition is generated at the far field of the electronic equipment, the loudness and definition of the sound are reduced, and therefore other people at the far field of the electronic equipment cannot hear the conversation sound, and the privacy of conversation is realized. In an application scene of the external power amplifier, the sound of the second vibrating diaphragm and the sound of the first vibrating diaphragm generate sounds with the same phase, so that the same-phase sound field superposition is formed, the sound loudness is enhanced, and the improvement of the external amplification effect of the electronic equipment is realized.
The first vibrating diaphragm and the second vibrating diaphragm send out the same-phase sound, namely indicate when two vibrating diaphragms work together, the volume of the sound that obtains after two way sound wave stack can be bigger. Therefore, in the case that the first diaphragm and the second diaphragm are in the same phase, the sound generated by the combination of the two diaphragms should be higher than the sound generated by one of the diaphragms alone, so when one of the diaphragms is broken, the sound generated by only one of the diaphragms cannot reach the sound generated by the combination of the two diaphragms, and at this time, the sound heard by the user is smaller than the sound when both of the two diaphragms are in normal operation, so when one of the diaphragms is broken, the sound of the other diaphragm needs to be properly improved, so that the user can hear the sound normally.
Sub-step 1032, in the case that the first diaphragm and the second diaphragm are emitting sounds with opposite phases, reducing the sound volume of the second diaphragm if the working state of the first diaphragm is a fault state, and reducing the sound volume of the first diaphragm if the working state of the second diaphragm is a fault state. And according to the audio frequency effect when the receiver and the loudspeaker work normally, the loudspeaker or the receiver frequency response is optimized to meet the user requirement.
In the embodiment of the application, under the condition that the first diaphragm and the second diaphragm emit sounds with opposite phases, if the two diaphragms work simultaneously, the sounds emitted by the first diaphragm and the sounds emitted by the second diaphragm can cancel each other, and the sound emitted by the combination of the two diaphragms should be lower than the sound emitted by one of the diaphragms alone, so when one of the diaphragms is broken, the sound emitted by only one of the diaphragms is larger than the sound emitted by the combination of the two diaphragms, and at the moment, the sound heard by a user is larger than the sound polarized when the two diaphragms work normally, therefore, when one of the diaphragms is broken, the sound of the other diaphragm needs to be reduced appropriately, so as to avoid the discomfort of ears of the user caused by the larger sound.
