Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
The terms first, second, third and the like in the description and in the claims and in the above drawings, are used for distinguishing between different objects and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Referring next to fig. 1, a schematic diagram of an audio processing system of an oral care device according to an embodiment of the present application is shown. As shown in fig. 1, the audio processing system of the oral care device may include: control unit, motor drive and motor. Wherein:
the control unit can be a micro control unit (Microcontroller Unit, MCU), also called a single-chip microcomputer or a single-chip microcomputer, which properly reduces the frequency and specification of a central processing unit (Central Process Unit, CPU), integrates peripheral interfaces such as a memory, a counter, USB, A/D conversion, UART, PLC, DMA and the like, and even LCD driving circuits on a single chip to form a chip-level computer, and performs different combination control for different application occasions.
Specifically, the control unit is used for decoding the audio file. The control unit comprises a flash memory space and a memory block. The flash memory space is a nonvolatile memory medium and is used for storing target audio files, and the flash memory space has high reliability, high reading and writing speed and low power consumption. The memory block may be, but is not limited to, a random access memory within the control unit, and may be, but is not limited to, a ring buffer for storing decoded data. A circular buffer, also called circular buffer, circular queue, circular buffer, is a data structure representing a fixed size, end-to-end buffer, suitable for buffering data streams.
Specifically, after the control unit obtains the target audio file, in order to avoid the problem that the storage chip in the control unit is full and affects the audio playing effect caused by the control unit of the inlet cavity nursing device at a time after the decoding of the target audio file is completed, one target audio fragment in the target audio file can be intercepted first to perform decoding processing to obtain corresponding target audio data, the decoded target audio data are stored in an annular buffer zone of the storage block, and finally, a corresponding target pulse modulation signal is output to the motor driving part based on the target audio data in the annular buffer zone of the storage block, so that the motor driving part drives the motor to output target audio corresponding to the target audio data in a bone conduction mode through swinging based on the target pulse modulation signal. After the output of the target audio data in the annular buffer zone of the storage block is completed, the next target audio segment in the target audio file can be intercepted for decoding processing to obtain corresponding target audio data, the target audio data obtained after the next target audio segment is decoded is stored in the annular buffer zone of the storage block again, and finally, a corresponding target pulse modulation signal is output to the motor driver based on the target audio data in the annular buffer zone of the storage block.
Optionally, in order to save the storage space in the annular buffer of the storage block and reduce the requirement for the storage space, after the output of the target audio data in the annular buffer of the storage block is completed, the target audio data in the annular buffer of the storage block is deleted, and then the target audio data decoded by the next target audio segment in the target audio file is stored in the annular buffer of the storage block.
It will be appreciated that the control unit may include one or more memory blocks, and embodiments of the present application are not limited in this regard. The target audio file may be, but is not limited to, an mp3 audio file, a wav audio file, or the like.
Optionally, after the control unit obtains the target audio file, the control unit may decode the target audio file first, store the target audio data obtained after decoding in a ring buffer area of the storage block in a segmented manner, and finally sequentially output corresponding target pulse modulation signals to the motor driver based on each segment of target audio data in the ring buffer area of the storage block, so that the motor driver drives the motor to output target audio corresponding to the target audio data in a bone conduction manner through swinging based on the target pulse modulation signals.
The motor driver may be a motor driver chip, and the motor may be, but not limited to, an acoustic motor. The motor driving piece is used for driving the motor to swing, and then playing audio in a bone conduction mode through the motor swing, or realizing oral care and the like through the motor swing.
It will be appreciated that the audio processing system of the above-described oral care device may be applied to oral care devices capable of oral care, such as, but not limited to, electric toothbrushes, mouthwashes, etc., to enable the oral care device to play audio. The oral care device may also, but is not limited to, be mounted with one or more indicators, one or more keys, a speaker, a motor, etc.
Next, an audio processing method of an oral care device according to an exemplary embodiment of the present application will be described with reference to fig. 1. Referring specifically to fig. 2, a flowchart of an audio processing method of an oral care device according to an embodiment of the present application is shown. As shown in fig. 2, the audio processing method of the oral care device includes the following steps:
s201, acquiring a target audio file.
Optionally, the oral care device may, but is not limited to, generate a corresponding target audio play instruction based on the target oral care information or a target oral care operation trigger of the user during oral care. After the oral care device acquires the target audio playing instruction, the oral care device can directly call out the corresponding target audio file from a plurality of audio files stored in advance. The target oral care operation may be, but not limited to, clicking, long pressing, short pressing, etc., and the target oral care information may be, but not limited to, including a total oral care time period longer than a preset total time period, a current oral care time period longer than a preset time period corresponding to a current oral care position, a current oral care pressure greater than a preset pressure, a current oral care amplitude greater than a preset amplitude, a current oral care mode being a music playing mode, etc. The preset total time period may be, but not limited to, 3 minutes or 2 minutes, 30 seconds, etc., and the preset time period may be, but not limited to, 30 seconds or 45 seconds, etc.
Alternatively, the oral care device may establish a connection with the terminal and, upon receiving the target audio play instruction, obtain a corresponding target audio file from the terminal in response to the target audio play instruction.
It can be appreciated that the target oral care mode currently corresponding to the oral care device is different, and the obtained target audio file is different; and/or the target oral care information corresponding to the oral care equipment is different, and the obtained target audio files are different. According to the embodiment of the application, the corresponding target audio file can be acquired aiming at different current oral care modes or different current oral care information, so that the oral care equipment can realize personalized playing of the audio, the oral care effect of a user can be ensured, and the user can know the current corresponding oral care information in the process of oral care through playing the audio to a certain extent.
S202, decoding the first target audio fragment in the target audio file to obtain first target audio data.
Specifically, after the target audio file is obtained, the oral care device may intercept a target audio segment, i.e., a first target audio segment, from the target audio file before playing the audio, and decode the first target audio segment to obtain corresponding target audio data,
And S203, storing the first target audio data into a storage block.
Specifically, a section of memory space (memory block) is divided first in the initialization stage of the program of the oral care device to store the decoded array file. After the first target audio fragment in the target audio file is decoded, the first target audio data obtained after decoding can be stored in the storage block, so that the cache of the target audio data obtained after decoding the target audio file is realized, and the requirement on the storage space of the oral care equipment is reduced.
It can be understood that, in order to ensure the smoothness of decoding and audio playing of the target audio file, the target audio data corresponding to each target audio segment in the target audio file should be smaller than or equal to the storage amount of the storage block, so as to avoid the problem that the decoding storage efficiency is affected by the overlarge target audio data corresponding to each target audio segment in the target audio file.
S204, outputting a corresponding first target pulse modulation signal to the motor driving part based on the first target audio data in the storage block, so that the motor driving part drives the motor to output the first target audio corresponding to the first target audio data through swinging based on the first target pulse modulation signal.
For example, after the oral care device acquires the target audio file, the oral care device may decode the first second audio segment of the target audio file, store the decoded first second audio data in a storage block opened in advance, and output a corresponding first target pulse modulation signal to the motor driver based on the first second audio data in the storage block, so that the motor driver drives the motor to output the first second audio corresponding to the first second audio data through swinging based on the first target pulse modulation signal.
In the embodiment of the application, the first target audio data is obtained by decoding the first target audio fragment in the target audio file, the first target audio data is stored in the storage block, and finally, the corresponding first target pulse modulation signal is output to the motor driving part based on the first target audio data in the storage block, so that the motor driving part drives the motor to output the first target audio corresponding to the first target audio data through swinging based on the first target pulse modulation signal, thereby avoiding the problem that the storage chip in the control unit is fully exploded to influence the audio playing effect due to the control unit of the next sub-plug inlet cavity nursing device after the target audio file is decoded, reducing the requirement on the storage space of the oral cavity nursing device, and enabling the oral cavity nursing device to efficiently and stably process the audio file in the process of playing the audio while carrying out oral cavity nursing through the pre-stored decoded audio data, and improving the smoothness of the synchronous playing of the audio of the oral cavity nursing device.
Alternatively, the first target audio data may include a signal obtained by superimposing the first target audio driving signal and the target cleaning driving signal. That is, the data in the target audio file may be a signal obtained by overlapping the target audio driving signal and the target cleaning driving signal in advance, that is, after the oral care device obtains the target audio file, no additional signal overlapping operation is required, and synchronous playing of the audio of the oral care device can be efficiently and smoothly realized while oral care is performed.
Alternatively, the first target audio data may include a first target audio driving signal. As shown in fig. 3, after decoding a first target audio segment in a target audio file and storing first target audio data obtained after decoding in a storage block, outputting a corresponding first target pulse modulation signal to a motor driver based on the first target audio data in the storage block may include: firstly, superposing a first target audio driving signal and a target cleaning driving signal in a storage block to obtain a first target pulse modulation signal; and then, outputting the first target pulse modulation signal to the motor driving part, so that the motor driving part drives the motor to output the first target audio corresponding to the first target audio data and perform oral care work corresponding to the target cleaning driving signal through swinging based on the first target pulse modulation signal.
