1. FM radio signal is unstable, strong when strong:
Most portable radios use an antenna-free design, but unlike the built-in antenna of a NOKIA mobile phone, it is not built-in, but uses a headphone cable as an antenna, so when you use a headset cable that is not a multi-strand enamelled or sandbag. The radio effect will be reduced. Generally, the original headphones are tested, and switching to other headphones may weaken the signal.
The person's posture and environment also affect the signal. The signal is generally weakest when the headphone cord is completely attached to the body. If you use an arm to support it, the signal is improved, which is more noticeable away from the tower. If you live within 40 kilometers of the launch pad, this is generally not the case.
Important note: The earphone antenna is not a very stable way, so you have to try to adapt to the antenna, not let the machine adapt to you.
2. The USB connection is not successful:
This kind of problem is not only on the MP3 , but also on DC or U disk, especially mobile hard disk. In addition to the damage to the USB cable or interface or problems with the machine, the most common is the lack of power. This makes it easy for self-powered devices to be easily connected and difficult to connect using USB powered devices.
Devices that use USB power, mainly U disk, mobile hard disk and MP3 , most of the self-powered are DC, scanner and camera. When the power supply is insufficient, you can try to remove the extension cable or use the rear USB port of the chassis to improve the use.
Front USB is generally not recommended, it is originally connected in the chassis using an extension cable. So the safest thing is the rear interface, which is soldered directly on the motherboard. If you must use an extension cord, you must buy a better one. The extension cord, which is usually very thick, has a large current and is not easy to supply power. The line I used myself was as thick as a pencil, and the plug was also gold-plated. On the market, it was 25 yuan. I have not reported that the power supply is insufficient.
3, the order of playback can not be determined, and the order is different on the computer, and is irregular:
Since MP3 /MP4 is compatible with U disk, it can't use its own storage format. It can only use the file system common to the computer. The file system supported by the existing WINDOWS is random storage mode, that is, the current use is the first one. The free space found to store the data, when the files in the partition are repeatedly modified, it will produce fragments of files and directories. At this time, the storage structure will be very confusing, reducing the efficiency of the file system. The directory of the file, which records the location where all the files are stored, will itself become confusing due to storage structure issues.
Usually, the files stored in one directory are sorted in the order of writing, that is, the files that are saved first are stored before, and when they are stored later. If the files are deleted in the middle, the files that are saved may also use the files that have been deleted before. Position, so that the last saved may be inserted into the middle.
MP3 because of CPU power reasons, including the main frequency memory and other factors, generally traversed to the directory, according to the contents of the directory to play. Sometimes this kind of function may make it inconvenient for users to use. Many people want to arrange the files according to certain rules as on the computer, but if so, MP3 will process all the contents of the directory when processing. And then store a table, if this table accounts for memory (RAM), it has a great impact on the use of the CPU. If you use the FLASH space, it will increase the consumption of FLASH and reduce the speed. The process of establishing this list alone, the centralized operation is quite long for the MCU whose performance is not high. It may be that users need to wait a long time when opening a new directory, like WINDOWS opens a directory with a lot of files for the first time, it will wait a long time.
In summary, MP3 generally does not deal with the playback order. But everyone can do it through software. Someone has posted it, the software is called DJ4 MP3 , it can change the directory list in the file system for you to achieve the storage order to meet your needs.
4. Crash or restart when playing MP3 or other files:
In this case, sometimes the player is not broken. If you pay attention, it is likely that you will always die in a specific place, such as the number of seconds of a certain piece of music. Because it may be caused by a bit error in the download of the media file.
Especially for multi-threaded downloads or files downloaded by Thunder, the probability of such errors is high. Once the error occurs, due to the limited processing power of the MCU and DSU on the Walkman, fault tolerance may not be as complete as that on the desktop computer, which may cause a crash or restart failure. Maybe someone has already experienced the use of a media player in WINDOWS to put the DIVX movie downloaded to BT to crash, right? Therefore, if it is a specific crash, it is often necessary to find a problem from the media source.
5, the available flash memory capacity does not reach the nominal, always several tens of megabytes less than the nominal:
Due to the structural relationship of the chip design, the player's own operating system is also stored in the flash memory, so it will take up some. Relatively speaking, the larger the capacity of the machine, the smaller the ratio, because the firmware size is the same.
Don't say that the manufacturer made a false advertisement. The firmware is equivalent to the operating system. Originally it takes up flash space, and because it can be replaced, the manufacturer can't say how much is used to store music, and the flash capacity refers to the internals. The size of the flash memory, no manufacturer said to be used to store the size of the media file. It's just that the average person is not sure, part of the flash will be used to store the firmware.
The above problems are more common soft faults. When you encounter them again, you may wish to check them first, and you may be able to solve them yourself. 1. FM radio signal is unstable, strong when strong:
