`
`SOUND PLAYER WITH A SEPARABLE MEMORY
`
`BACKGROUND OF THE INVENTION
`
`:0001]
`
`1. Field of the Invention
`
`:0002] The present invention relates to a sound player, and
`more particularly,
`to a sound player with a separable
`nemory.
`
`:0003]
`
`2. Description of the Prior Art
`
`:0004] With the advent of digital music being readily
`available, users have a new source of musical content.
`Digital music content resides in relatively small digital files
`hat can be stored on portable non-volatile memory devices.
`Due to the popularity of digital music, portable music
`olayers such as Moving Pictures Expert Group, Layer 3
`MP3) players, as well as other types of music players can
`3e found everywhere.
`
`:0005] Generally there are two kinds of MP3 players,
`classified according to the format of the memory used for
`storing music data. One utilizes flash memory, and the other
`tilizes hard disks. The MP3 player with the flash memory
`is popular for its small size and its light weight. However,
`he MP3 player with the flash memory has a fixed amount of
`nemory available for storing digital music. As an example,
`suppose that the flash memory has a capacity of 64 MB,
`which can store about one hour of digital music in the MP3
`format. If the user wishes to go on an extended trip, he will
`quickly run out of new songs to listen to on the MP3 player
`due to the small capacity of the flash memory. In order to
`overcome these problems, the user must buy multiple MP3
`olayers. Unfortunately, having more than one MP3 player
`greatly increases the cost associated with enjoying digital
`music. To overcome the drawback of memory capacity of
`he MP3 player with the flash memory, the MP3 player with
`he hard disk is designed for enlarging the amount of
`nemory for storing digital music data. However, an MP3
`slayer with a hard disk has the disadvantages of having a
`eavy weight, consuming more electricity, and being fragile.
`Hence there is a need to combine the advantages of the two
`VIP3 players for providing users with a better portable music
`olayer.
`
`SUMMARY OF THE INVENTION
`
`
`
`
`
`
`It is therefore a primary objective of the claimed
`:0006]
`i1vention to provide a sound player with a separable
`nemory.
`
`:0007] According to the claimed invention, a sound player
`includes a first module, a first connector, and a memory
`electrically connected to the first comiector for storing
`cigital audio data. The sound player further includes a
`second module, a controller for controlling the operation of
`tie sound player, a flash memory electrically connected to
`tie controller for storing digital audio data, a second con-
`ector electrically connected to the controller for connecting
`to the first connector in a detachable manner, a user interface
`to input a signal to the controller for selecting digital audio
`cata stored in the flash memory of the second module or for
`selecting digital audio data stored in the memory of the first
`module through the first connector and the second connec-
`tor, a decoder for converting selected digital audio data into
`audio signals, and an audio output port for outputting the
`audio signals.
`
`[0008] These and other objectives of the present invention
`will no doubt become obvious to those of ordinary skill in
`the art after reading the following detailed description of the
`preferred embodiment that is illustrated in the various fig-
`ures and drawings.

`
`nemory card. The radio receiver 40 is capable of receiving
`‘adio signals, such as PM or AM radio signals, and is
`capable of outputting audio signals corresponding to the
`‘adio signals to the audio output port 34. The power supply
`42 is capable of providing the electricity to the second
`nodule 20. The power supply 42 can be a battery or can
`‘eceive the electricity from an external power supply. In
`addition, the power supply 19 of the first module 12 can
`‘eceive the electricity from the power supply 42 of the
`second module 20 for providing the electricity to the first
`nodule 12.
`
`:0014] The characteristic of the present invention is that
`he sound player 10 includes the two parts, the first module
`12 and the second
`nodule 20. The data transmission
`jetween the first module 12 and the second module 20 's
`
`
`
`hrough the connection of the first connector 16 and the
`second connector 28. The first connector 16 and the second
`connector 28 can use he USB interface, such as USB 1.0,
`LU
`USB 2.0, or USB OTG, the IEEE 1394 interface, or the 1D:
`interface. If the first co mector 16 is a USB connector and th
`
`
`
`('D wL11L11
`
`memory 18 of the first module 12 is a hard disk of the 1D:
`interface, the first mod le 12 can further include a USB/ID,
`interface converter f0‘ converting data between the US
`interface and the DE i terface. As shown in FIG. 1, the first
`connector 16 is a male connector and the second comiector
`28 is a female c01mec or. The connection between the first
`connector 16 and the second connector 28 can also use other
`
`types and standards jesides the ones mentioned above.
`When the first module 12 and the second module 20 are
`
`connected through the connection of the first connector 16
`and the second connector 28, the user can select the digital
`audio data stored in the flash memory 26 of the second
`module 20 or the digital audio data stored in the memory 18
`of the first module 12 through the connection of the first
`connector 16 and the second connector 28 by the user
`interface 30. Therefore, the total capacity for storing digital
`audio data in the sound player 10 is the sum of the capacity
`of the flash memory 26 and the capacity of the memory 18.
`The combination of the first module 12 and the second
`
`module 20 is similar to an MP3 player with a hard disk in
`the prior art. The first module 12 is similar to an external
`hard disk for connecting to a computer to download digital
`audio data to the memory 18 of the first module 12. After
`downloading digital audio data from the computer and
`storing digital audio data to the memory 18 of the first
`module 12, the first module 12 can be disconnected from the
`computer and be connected to the second module 20. After
`the controller 24 of the second module 20 detects the
`connection of the first connector 16 and the second connec-
`
`tor 28, the first module 12 can be regarded as a slave device.
`And then the user interface 30 is operable to allow the user
`to select the digital audio data stored in the flash memory 26
`of the second module 20 or the digital audio data stored in
`the memory 18 of the first module 12 through the connection
`of the first connector 16 and the second connector 28. The
`
`user also can backup the digital audio data stored in the
`memory 18 of the first module 12 to the flash memory 26.
`If the user wants to take the sound player 10 outside for a
`long time, like going on a trip, the first module 12 can be
`connected to the second module 20 for storing more digital
`audio data.
`
`[0015] When the first module 12 is disconnected from the
`second module 20 of the sormd player 10, the controller 24
`will detect the disconnection of the first connector 16 and the
`
`second connector 28. And then the user interface 30 is
`
`operable to allow the user to select the digital audio data
`stored in the flash memory 26 of the second module 20. The
`second module 20 which is stand-alone is similar to an MP3
`
`player with a flash memory in the prior art and is light,
`portable, and electricity-saving. The second module 20 is
`capable of reading data stored in an external memory card
`through the memory card slot 38 so as to be a card reader.
`The source of the digital audio data stored in the flash
`memory 26 of the second module 20 can be from the
`memory 18 of the first module 12 through the connection of
`the first connector 16 and the second connector 28, or from
`the external memory card through the memory card slot 38.
`If the user has no need to listen a large number of digital
`audio data ordinarily, the second module 20 can function as
`a stand-alone MP3 player and have the advantages of being
`light, portable, and electricity-saving.
`
`In contrast to the conventional MP3 player, the
`[0016]
`sound player according to the present invention combines
`the advantages of the MP3 players with a flash memory and
`those with a hard disk. If the user wants to take the sound
`
`player 10 outside for a long time, such as when going on a
`trip, the first module can be connected to the second module
`for storing a large number of digital audio data. If the user
`has no need to listen a large number of digital audio data
`ordinarily, the second module can be a stand-alone MP3
`player for being light, portable, and electricity-saving.
`
`[0017] Those skilled in the art will readily observe that
`numerous modifications and alterations of the device and
`
`method may be made while retaining the teachings of the
`invention. Accordingly,
