Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Most of The existing mobile terminals have an On-The-Go (OTG) function, and The mobile terminals can perform data transmission with a USB (Universal Serial Bus) external sound card through The OTG function. The USB external sound card is a very common external power amplifier device, and is a hardware capable of implementing analog-to-digital conversion of data related to sound. The USB external sound card can be connected with the electronic equipment through a USB bus, can provide better audio recording and playback quality than an integrated sound card for the electronic equipment, and can also expand a multichannel audio output and input Interface, a MIDI (musical Instrument Digital Interface), an XLR (cross linked radio Interface), an optical fiber Interface and the like for the electronic equipment.
The external sound card of USB uses the scene also is more, but the external sound card of USB on the market is of a great variety, and when electronic equipment need insert the external sound card of USB, can not confirm which kind of the external sound card of USB can insert. When some sound cards are connected to the electronic equipment, the problem of pause of sound playing can occur.
The inventor finds that each USB external sound card has respective parameter configuration and different supported data transmission rates, and therefore when the mobile terminal is connected with the USB external sound card, the drive parameters of the electronic device may not match with the device parameters of the USB external sound card, and the USB external sound card plays music, and the like. For example, the data transmission rate corresponding to the driving parameter is greater than a parameter related to the data transmission rate in the device parameters of the USB external sound card, and the electronic device transmits the audio data at a greater transmission rate than the USB external sound card, but the processing speed of the USB external sound card on the audio data cannot keep up with the transmission speed of the electronic device, so that the audio data processed by the USB external sound card is blocked during playing. For example, after the USB driver of the electronic device encodes PCM (Pulse Code Modulation) data into a data packet with a certain format, the data packet is not matched in the middle of the data packet when being transmitted to the external sound card, which causes the data obtained by the external sound card to be too fast or too slow, and further causes the problem of pause or noise in playing.
If the ADSP (Digital signal processing chip (DSP) scheme produced by American Analog Device Instrument (ADI)) scheme which has strong platform dependence is adopted, the USB audio scheme native to *** used by many platforms does not support the ADSP scheme, the application range is limited, and the compatibility of the electronic equipment to the USB external sound card is limited. Therefore, the inventor proposes a method for adjusting driving parameters in the application, and obtains a rate parameter of the USB external sound card, where the rate parameter is related to a data transmission rate; judging whether the speed parameter is matched with a parameter value of a driving parameter for driving the USB external sound card; if not, acquiring a parameter value of a driving parameter matched with the USB external sound card as a target parameter value; the driving parameters are adjusted to be the target parameters, and the parameter values of the driving parameters are adjusted under the condition that the speed parameters of the USB external sound card are not matched with the parameter values of the driving parameters, so that the parameter values of the driving parameters are matched with the speed parameters of the USB external sound card, the phenomenon of sound blocking caused by the fact that the parameter values of the driving parameters are not matched is avoided, and the user experience is improved.
The following will describe embodiments of the present application in detail.
Referring to fig. 1, an embodiment of the present application provides a method for adjusting driving parameters, and an execution main body of a processing flow described in this embodiment may be an electronic device. The method comprises the following steps:
step S110, obtaining a rate parameter of the USB external sound card, wherein the rate parameter is related to the transmission rate of data.
When the electronic equipment detects the access of the USB external sound card, the electronic equipment can acquire the speed parameter of the accessed USB external sound card so as to determine the appropriate data transmission speed between the electronic equipment and the USB external sound card.
For example, the identity of the USB external sound card may be obtained during enumeration, and the rate parameter of the USB external sound card may be searched according to the identity.
For another example, a device descriptor, an endpoint descriptor, and parameters related to the transmission rate of data of the USB external sound card may be obtained during the enumeration process. The rate parameter of the USB external sound card refers to a parameter related to a transmission rate of data, and the specific parameters are not limited in this embodiment.
For example, when the electronic device performs data transmission with the USB external sound card, audio data is sent to the USB external sound card at preset time intervals, and the audio data is sent to the USB external sound card in the form of data packets. Therefore, the larger the data packet sent by the electronic device to the USB external sound card is, the larger the data transmission rate between the electronic device and the USB external sound card is. Thus, the rate parameter in the embodiments of the present application may be the maximum packet length (wmaxpcacketsize) in the endpoint descriptor.
Of course, the rate parameter may also be other parameters related to the transmission rate of data, such as an access interval (bInterval) for specifying the endpoint data transmission. It is understood that the smaller the access interval, the more data transmission times, and the higher the corresponding data transmission rate.
Specifically, when the USB external sound card is connected to the electronic device, the electronic device does not know what device is connected to the electronic device, so the electronic device can send a request to the connected USB external sound card, and the USB external sound card can feed back the relevant configuration parameters of the electronic device when receiving the request sent by the electronic device. And the electronic equipment acquires the relevant configuration parameters of the accessed USB external sound card, and then can determine the parameter values of the driving parameters for driving the USB external sound card.
And step S120, judging whether the speed parameter is matched with a parameter value of a driving parameter for driving the USB external sound card.
When the rate parameter of the USB external sound card is obtained, the electronic device may select a suitable driving parameter to drive the USB external sound card.
The electronic device may automatically select a default driving parameter for driving the USB external sound card in the electronic device when the rate parameter of the USB external sound card is obtained, or may automatically select the default driving parameter according to the driving parameter obtained when the USB external device is accessed last time, but the selected driving parameter may not be matched with the driving parameter of the currently accessed USB external sound card. At this time, the electronic device may determine whether the rate parameter matches a parameter value of a driving parameter for driving the USB external sound card.
And judging whether the speed parameter is matched with the parameter value of the driving parameter for driving the USB external sound card or not in different modes. In an embodiment, it may be determined whether a parameter value of the driving parameter is consistent with the rate parameter, and if the parameter value of the driving parameter is not consistent with the rate parameter, it may be determined that the rate parameter is not matched with the parameter value of the driving parameter for driving the USB external sound card.
In another embodiment, the electronic device may determine whether a parameter value of the driving parameter is within a range in which the USB external sound card is driven to operate normally, where the normal operating range is a parameter range corresponding to a rate parameter at which the USB external sound card does not generate a stuck state. For different USB external sound cards, the parameter range of the speed parameter which can work normally can be set, so that whether the current driving parameter in the electronic equipment is in the parameter range of the normal work of the currently accessed USB external sound card can be judged. The parameter range of the speed parameter of the USB external sound card in normal operation may be smaller than the parameter value of the speed parameter of the USB external sound card, or may be a difference smaller than the parameter value of the speed parameter of the USB external sound card. In addition, the set parameter range of the speed parameter of the USB external sound card working normally can also be a range interval from one parameter value to another parameter value.
And if the parameter value of the driving parameter is not in the normal working range of the driving USB external sound card, judging that the speed parameter is not matched with the parameter value of the driving parameter for driving the USB external sound card.
And step S130, if the speed parameters are not matched, acquiring a parameter value matched with the speed parameter of the USB external sound card as a target parameter value.
If the rate parameter is judged not to be matched with the parameter value of the driving parameter for driving the USB external sound card, it is indicated that if the parameter value of the driving parameter is continuously used for driving the USB external sound card, driving failure may occur, or after the USB external sound card is successfully driven, the situation that normal playing is influenced by pause, noise and the like may occur in the process of playing sound when the USB external sound card is normally used.
Then, if it is determined that the rate parameter does not match the parameter of the driving parameter for driving the USB external sound card, a parameter value matching the driving parameter of the USB external sound card may be obtained as a target parameter value.
Step S140, adjusting the driving parameter to the target parameter value.
And if the target parameter value is a parameter value which can be matched with the driving parameter of the USB external sound card, adjusting the driving parameter to the target parameter value to drive the USB external sound card.
In the embodiment of the application, the electronic device can acquire the speed parameter of the USB external sound card through the USB driver in the electronic device. After the USB drive acquires the speed parameters of the USB external sound card, the speed parameters can be transmitted to a matching unit of the electronic equipment, and the matching unit acquires the driving parameters of the electronic equipment from the audio drive of the electronic equipment to perform matching judgment. After the driving parameters are obtained, the audio driver can send a data packet to the USB driver, and then the USB driver sends the data packet to the USB external sound card. And the data packet sent to the USB external sound card is encoded and sent by taking the adjusted driving parameters as a standard.
In addition, in the embodiment of the present application, if the rate parameter matches a parameter value of a driving parameter for driving the USB external sound card, the current driving parameter may be directly used for driving, and data interaction, such as data encoding and sending, or data receiving, may be performed with the USB external sound card using the driving parameter as a standard.
The method for adjusting the driving parameters obtains the speed parameters of the USB external sound card, wherein the speed parameters are related to the transmission speed of data; judging whether the speed parameter is matched with a parameter value of a driving parameter for driving the USB external sound card; if not, acquiring a parameter value of a driving parameter matched with the USB external sound card as a target parameter value; and adjusting the driving parameters to target parameters. Under the condition that the speed parameter of the USB external sound card is not matched with the parameter value of the driving parameter, the parameter value of the driving parameter is adjusted, so that the parameter value of the driving parameter is matched with the speed parameter of the USB external sound card, the phenomenon of sound blocking caused by the fact that the parameter value of the driving parameter is not matched is avoided, and the user experience is improved.
Referring to fig. 2, another embodiment of the present application provides a method for adjusting driving parameters, where the embodiment focuses on a process of obtaining a rate parameter of a USB external sound card on the basis of the foregoing embodiment, and the method may include:
step S210, receiving the identity sent by the USB external sound card.
When the USB external sound card is accessed into the electronic equipment through the interface, a USB enumeration process is carried out, namely, some information is read from the USB external sound card, so that the user can know what equipment is accessed into the electronic equipment and how to carry out communication, and a proper driving program is loaded according to the information, so that the USB external sound card is driven. The obtained information comprises the identity of the USB external sound card, and different identity characters represent the USB external sound cards with different parameter characteristics.
Specifically, in the enumeration process, the electronic device may send a request to the USB external sound card, and the USB external sound card may send its own information to the electronic device one by one after receiving the request. Therefore, the electronic equipment can acquire the identity sent by the USB external sound card, and the identity can be a product ID in the equipment descriptor.
And S220, searching the speed parameter of the USB external sound card according to the identity.
When the electronic equipment receives the identity mark sent by the USB external sound card, the speed parameter of the USB external sound card can be searched according to the identity mark.
In an embodiment, a first device information table is stored in the electronic device, where the first device information table includes identification identifiers of different USB external sound cards and a rate parameter of the USB external sound card corresponding to the identification identifiers, for example, the first device information table may be as shown in table 1.
TABLE 1
| Identity label | A | B | C |
| Rate parameter | a | b | c |
The identification marks in the first device information table are identification marks of different USB external sound cards, for example, the identification mark of one USB external sound card is "a", and the identification mark of the other USB external sound card is "B". The rate parameter is a rate parameter of a different USB external sound card, for example, a USB external sound card with an identity "a", and the corresponding rate parameter is "a"; and the corresponding speed parameter of the USB external sound card with the identity label of B is B. Then, the electronic device may query the device information table according to the received identity of the USB external sound card, so as to obtain the rate parameter of the USB external sound card corresponding to the identity. For example, if the identification "C" sent by the USB external sound card received by the electronic device is found, the device information table, i.e., table 1, is queried according to the identification "C", and the rate parameter of the USB external sound card corresponding to the identification "C" is found to be "C".
Step S230, determining whether the rate parameter matches a parameter value of a driving parameter for driving the USB external sound card.
After the rate parameter of the USB external sound card is obtained, the electronic device may load an appropriate driver according to the rate parameter of the USB external sound card. However, a parameter value of a driving parameter of a driver in the electronic device may not match the acquired rate parameter of the USB external sound card, and if the driving program with the unmatched parameter is selected to drive the USB external sound card, a situation that a sound card is stuck in normal use of the USB external sound card may occur due to a driving failure or a successful driving.
Step S240, if not, obtaining the parameter value matched with the speed parameter of the USB external sound card as the target parameter value,
step S250, adjusting the driving parameter to the target parameter value.
The steps S240 to S250 refer to corresponding parts of the foregoing embodiments, and are not described herein again.
According to the method for adjusting the driving parameters, the electronic equipment can acquire the speed parameters of the USB external sound card by receiving the identity sent by the accessed USB external sound card and inquiring the first equipment information table through the identity. Judging whether the rate parameter is matched with a parameter value of a driving parameter for driving the USB external sound card; if not, acquiring a parameter value of a driving parameter matched with the USB external sound card as a target parameter value; and adjusting the driving parameters to target parameters. The speed parameters of the accessed USB external sound card are acquired in different modes, so that the condition that the speed parameters of the USB external sound card cannot be acquired is avoided, and a foundation is provided for subsequent steps.
Referring to fig. 3, another embodiment of the present application provides a method for adjusting driving parameters, where the present embodiment focuses on a process of determining whether the rate parameter matches a parameter value of a driving parameter on the basis of the foregoing embodiment, and the method may include:
step S310, obtaining a rate parameter of the USB external sound card, wherein the rate parameter is related to the transmission rate of data.
Step S320, querying the rate parameter in a second device information table, and determining whether the rate parameter matches the parameter value of the driving parameter according to the query result.
In one embodiment, when accessing the USB external sound card, the electronic device first selects default driving parameters. In this embodiment, the electronic device pre-stores a second device information table, where the second device information table includes a parameter value of a default driving parameter and a rate parameter of a corresponding matched USB external sound card. When the speed parameter of the USB external sound card is obtained and it is determined whether the speed parameter matches a parameter value of a driving parameter for driving the USB external sound card, the speed parameter may be searched in the second information table, and the searched parameter value is specifically the parameter value of the speed parameter of the USB external sound card. If the current driving parameters are found, the USB external sound card can be driven by the current driving parameters of the electronic equipment, so that the USB external sound card can work normally, otherwise, the USB external sound card cannot work normally under the current driving parameters.
In another embodiment, the current driving parameters that the electronic device first selects are not determined, and may be, for example, random or selected based on a previous insertion of the USB external device. In this embodiment, the electronic device may pre-store a second device information table, where the second device information table includes different parameter values of the driving parameter and a rate parameter corresponding to the matched USB external sound card. When the rate parameter of the USB external sound card is obtained, a second device information table may be queried according to the rate parameter of the USB external sound card. Specifically, it may be determined whether a parameter value of the USB external sound card rate parameter is found in the rate parameter corresponding to the current driving parameter of the electronic device in the second device information table. The second device information table includes parameter values of the driving parameters and matched rate parameters. Specifically, the second device information table may refer to table 2.
TABLE 2
| Rate parameter | d | e | f | g |
| Parameter value of driving parameter | D | E | F | G |
The second device information table in table 2 indicates the parameter value of the driving parameter corresponding to the rate parameter, which is a parameter value of the driving parameter that can be supported by the electronic device. The electronic device may determine a parameter value of the currently selected driving parameter, and when the rate parameter of the USB external sound card is obtained, the electronic device may query the second information device table according to the rate parameter of the USB external sound card. If the speed parameter of the USB external sound card is found in the speed parameter corresponding to the current driving parameter in the second device information table, the electronic device may normally drive the USB external sound card, so that it may be determined that the speed parameter matches the driving parameter.
In another embodiment, the electronic device may include a second device information table prestored in advance, where the second device information table may include ranges of parameter values of driving parameters corresponding to different rate parameters of the USB external sound card, and the parameter ranges are parameter ranges within which the USB external sound card can be driven to normally operate. Namely, the parameter value of the driving parameter is within the preset range, the USB external sound card can be successfully driven to normally work. In this embodiment, specifically, the second device information table may refer to table 3.
TABLE 3
| Rate parameter | d | e | f | g |
| Parameter value range of driving parameter | H～K | L～O | P～S | T～W |
In this embodiment, the different rate parameters in table 3 represent rate parameters of the USB external sound card, and the parameter value range of the driving parameter is a range that the parameter value of the driving parameter of the electronic device can be selected under the corresponding rate parameter. Then, when the rate parameter of the USB external sound card is obtained, the second device information table may be queried according to the obtained rate parameter of the USB external sound card, specifically, whether a parameter value of the currently selected driving parameter of the electronic device is queried within a parameter range of the driving parameter corresponding to the rate parameter of the currently accessed USB external sound card. And when the parameter value of the driving parameter is in the parameter value range of the driving parameter corresponding to the rate parameter, determining that the rate parameter is matched with the driving parameter, and if the parameter value of the driving parameter is not in the parameter value range of the driving parameter corresponding to the rate parameter, determining that the rate parameter is not matched with the driving parameter.
For example, if the acquired rate parameter is e and the parameter value of the driving parameter is S, the parameter value range of the corresponding driving parameter is queried to be L to O according to the acquired rate parameter e, and if S is not between L and O, it can be determined that the rate parameter is not matched with the driving parameter.
And step S330, if the rate parameter is not matched with the parameter value of the driving parameter, acquiring the parameter value matched with the rate parameter of the USB external sound card as a target parameter value.
And if the rate parameter is judged not to be matched with the parameter value of the driving parameter, acquiring the parameter value matched with the rate parameter of the USB external sound card as a target parameter value. In an embodiment, the acquired rate parameter of the USB external sound card may be directly used as a target parameter value, for example, the acquired rate parameter of the USB external sound card is f, and when it is determined that the rate parameter does not match the parameter value of the driving parameter, f is used as the target parameter value.
In another embodiment, the parameter value within the range of the parameter value of the driving parameter corresponding to the speed parameter may be used as the target parameter value. For example, the obtained rate parameter of the USB external sound card is d, and when it is determined that the rate parameter does not match the parameter of the driving parameter, any value in the parameter value range H to K of the driving parameter corresponding to the rate parameter d is used as the target parameter value, or H or K is used as the target parameter value.
In one embodiment, a value within a preset range of the rate parameter may be used as the target parameter. For example, taking a parameter value smaller than the rate parameter of the currently accessed USB external sound card as a target parameter value; or taking the parameter value within the range smaller than the speed parameter of the USB external sound card by a preset value as the target parameter value.
Step S340, adjusting the driving parameter to the target parameter value.
Step S340 may refer to steps corresponding to the foregoing embodiments, and will not be described herein again.
The method for adjusting the driving parameters obtains the speed parameters of the USB external sound card, wherein the speed parameters are related to the transmission speed of data; judging whether the speed parameter is matched with a parameter value of a driving parameter for driving the USB external sound card; if not, acquiring a parameter value of a driving parameter matched with the USB external sound card as a target parameter value; and adjusting the driving parameters to target parameters. Under the condition that the speed parameter of the USB external sound card is not matched with the parameter value of the driving parameter, the parameter value of the driving parameter is adjusted, so that the parameter value of the driving parameter is matched with the speed parameter of the USB external sound card, and the phenomenon of sound blocking caused by the fact that the parameter value of the driving parameter is not matched is avoided.
It can be understood that the method for adjusting driving parameters provided by the present application is not only applicable to a USB external sound card, but also applicable to various USB external devices.
