[0029] Example 1

[0030] A CD player is an audio device used to read and play audio data stored on a CD. Its working principle is to use a laser head to emit a laser beam to illuminate the CD, and receive the optical signal reflected by the CD for signal conversion and output. CD players in the prior art need to read the CD continuously, which places high demands on the real-time reading function of the laser head, and are prone to physical wear and tear on the CD and the laser head, reducing the service life of the CD player. For this, please refer to Figure 1 The embodiment of the present application provides an optical disc player 100, comprising: a main control module 110, a drive module 120, a reading module 130 and a data storage module 140; the main control module 110 is electrically connected to the drive module 120 and the data storage module 140 respectively; the drive module 120 is also electrically connected to the reading module 130.

[0031] In this embodiment, the reading module 130 includes: a laser head for emitting a preset optical signal to the audio storage device 200, and a photodiode for receiving the optical signal reflected back by the audio storage device 200. The audio storage device 200 includes an optical disc. It can be understood that an optical disc is an optical medium for storing digital data, and a series of grooves and flat lands are arranged on its surface in a spiral track, extending outward from the center of the optical disc. Since the grooves and flat lands on the optical disc reflect light differently, during the reading process, the intensity of the optical signal reflected back by the grooves and the optical signal reflected back by the flat land received by the photodiode is different. According to the optical signals of different intensities, the corresponding storage data, i.e., the audio data described below, can be obtained.

[0032] The main control module 110 is used to send a control signal to the driving module 120 when it is detected that the audio storage device 200 is in place; the driving module 120 is used to send a driving signal to the reading module 130 when the control signal is obtained; the reading module 130 is used to send a preset light signal to the audio storage device 200 according to the driving signal, and when the preset light signal is received, the audio storage device 200 is used to send a reflected light signal to the main control module 110; the main control module 110 is also used to determine multiple audio data according to the reflected light signal, and store each audio data in the data storage module 140.

[0033] It can be understood that the audio data stored in the audio storage device 200 is digital data, and by sending a preset optical signal to the audio storage device 200 and receiving the optical signal reflected back by the audio storage device 200, the audio data stored in the audio storage device 200 is sent to the main control module 110 in the form of an optical signal, and the main control module 110 converts the reflected optical signal into a digital form and stores it in the data storage module 140. The parameters such as the frequency, power, and wavelength of the preset optical signal can be set according to actual conditions.

[0034] In one embodiment, see Figure 2 The optical disc player 100 also includes: an interactive module 150 electrically connected to the main control module 110, used to obtain an interactive signal and send it to the main control module 110; the main control module 110 is also used to call target audio data from multiple audio data stored in the data storage module 140 according to the interactive signal.

[0035] The interaction module 150 includes: physical buttons, touch screen, remote control or user terminal device. The interaction module 150 sends the acquired interaction signal to the main control module 110. The main control module 110 determines and calls the target audio data from the multiple audio data stored in the data storage module 140 according to the interaction signal.

[0036] Furthermore, the main control module 110 outputs the target audio data. It can be understood that the target audio data is a digital signal. In the present embodiment, the main control module 110 outputs the target audio data to the conversion module 160, and the conversion module 160 converts the target audio data into an analog signal and then outputs it. In other embodiments, the main control module 110 can also output the target audio data to the interaction module 150, and display the target audio data through the interaction module 150.

[0037] In one embodiment, see Figure 3 The optical disc player 100 further includes: a conversion module 160 electrically connected to the main control module 110, for acquiring the target audio data from the main control module 110, converting the target audio data into an analog signal and then outputting it.

[0038] It can be understood that the target audio data is SPDIF data or IIS data, and needs to be converted into analog audio data, i.e., analog signal, before output. Specifically, the conversion module 160 includes: a digital-to-analog converter (DAC) for converting the target audio data into an analog signal. Further, the conversion module 160 also includes: a low-pass filter for filtering out high-frequency components in the analog signal before outputting the analog signal to improve the sound quality of the final output audio signal.

[0039] In one implementation, the conversion module 160 includes a digital-to-analog converter for converting the target audio data into the analog signal.

[0040] In this embodiment, the conversion module 160 includes a digital-to-analog converter. In other embodiments, the conversion module 160 may also select other components, specifically based on the ability to achieve digital-to-analog conversion.

[0041] In one embodiment, see Figure 4 The optical disc player 100 further includes: an output module 170 electrically connected to the conversion module 160, for acquiring the analog signal from the conversion module 160, amplifying the analog signal, and outputting the amplified analog signal.

[0042] The output module 170 is electrically connected to the output end of the conversion module 160, and is used to receive the analog signal output by the conversion module 160, and amplify the analog signal and output it to a speaker or other playback device to achieve audio playback. It can be understood that the amplification factor of the output module 170 is adjustable, specifically, by, for example, receiving an adjustment signal through an audio adjustment button, and adjusting the amplification factor of the analog signal according to the adjustment signal.

[0043] In one embodiment, the audio storage device 200 includes: an optical disc, and the main control module 110 is also used to obtain ID3 information of each audio data before storing the audio data in the data storage module 140, and mark and sort the audio data according to the corresponding ID3 information.

[0044] ID3 information is a metadata attached to audio data, including song title, artist, album and other information. The main control module 110 will mark each audio data according to the acquired ID3 information, such as naming or adding tags, and sort the audio data, such as sorting by artist name, album name or playlist order. Such processing makes the audio data more orderly and convenient for management and playback.

[0045] In one embodiment, the optical disc player 100 also includes: a detection module electrically connected to the main control module 110, for receiving an infrared light signal, and when the signal strength of the infrared light signal is greater than or equal to a preset intensity threshold, determining that the audio storage device 200 is not in place; when the signal strength of the infrared light signal is less than the preset intensity threshold, determining that the audio storage device 200 is in place.

[0046] In this embodiment, the detection module includes: an infrared sensor, and the infrared sensor includes: an infrared transmitter and an infrared receiver. It can be understood that the infrared transmitter is used to transmit infrared light signals to the outside, and the infrared receiver is used to receive the reflected infrared light signals. When the audio storage device 200 is inserted into the optical disc player 100, that is, the audio storage device 200 is in place, the infrared light signal emitted by the infrared transmitter is blocked, resulting in a reduction in the infrared light signal received by the infrared receiver, and the signal strength of the infrared light signal is less than a preset threshold; when the audio storage device 200 is not inserted into the optical disc player 100, that is, the audio storage device 200 is not in place, the infrared light signal emitted by the infrared transmitter is directly received by the infrared receiver, and the signal strength of the infrared light signal is greater than or equal to the preset threshold.

[0047] In other embodiments, the detection module may also be: a mechanical switch, a capacitive sensor, or a weight sensor, which is only used as an example and not as a limitation.

[0048] The optical disc player provided by the embodiment of the present application includes: a main control module, a drive module, a reading module and a data storage module; the main control module is electrically connected to the drive module and the data storage module respectively; the drive module is also electrically connected to the reading module; the present application is through the main control module sending a control signal to the drive module when it is detected that the audio storage device is in place; when the control signal is obtained, the drive module sends a drive signal to the reading module; the reading module sends a preset light signal to the audio storage device according to the drive signal, and when the preset light signal is received, the audio storage device sends a reflected light signal to the main control module; the main control module determines multiple audio data according to the reflected light signal, and stores each of the audio data in the data storage module, thereby realizing one-time reading and storage of audio data, avoiding physical loss caused by continuous and repeated reading of the optical disc, and improving the service life of the optical disc player.

[0050] In addition, the present application also provides a playback method, which is applied to the optical disc player described in Example 1, see Figure 5 The playing method includes: steps S510 to S540.

[0051] Step S510: When it is detected that the audio storage device is in place, the main control module sends a control signal to the driving module.

[0052] Step S520: When the control signal is acquired, the driving module sends a driving signal to the reading module.

[0053] Step S530: the reading module sends a preset light signal to the audio storage device according to the driving signal. When receiving the preset light signal, the audio storage device is used to send a reflected light signal to the main control module.

[0054] Step S540: the main control module determines a plurality of audio data according to the reflected light signal, and stores each of the audio data in the data storage module.

[0055] In one embodiment, the method further includes: the interaction module acquires the interaction signal and sends it to the main control module; the main control module calls the target audio data from the multiple audio data stored in the data storage module according to the interaction signal.
