Abstract

A mobile phone with digital music and repeating functions includes a mobile phone baseband chip (1). The invention is characterized in that the invention also includes a multi-media chip (2) which is two-way electrically connected with the mobile phone baseband chip (1), is provided with a mp3 playing function and a management memory unit and outputs mp3 decoding signals, a music processor (3) which is two-way electrically connected with the multi-media chip (2) and receives mp3 decoding signals for processing and outputs voice signals, an earphone or a loudspeaker which is electrically connected with the output terminal of the music processor (3), a memory in the mobile phone baseband chip (1), which stores mp3 data and eastalishes an mp3 recycling play function module (5) and an AB section play function module (6), and the two functional modules (5 and 6) are implemented by the processor in the baseband chip (1) and respectively started by the recycling play functional keys on the panel of the mobile phone and controlled by a key A and a key B. The invention adds mp3 and repeating functions to the mobile phone, which saves the expenditure on purchasing a repeater independently and is convenient for carrying.

Description

Mobile phone with digital music repeating function

Technical field

The present invention relates to the mobile phone of a kind of mp3 of having (digital music) record function.

Background technology

People need listen for one time one time repeatedly in order to learn foreign languages, and go imitation.The appearance of cassette tape formula language repeater has made things convenient for people's study.But cassette tape formula language repeater also has a lot of shortcomings:

1, volume is big, carries inconvenience;

2, reading repeatedly of cassette tape, also very serious to the wearing and tearing of tape and magnetic head;

3, audio distortions, this language repeater are first the sound on the tape, utilize cheap A/D converter (being generally 8 or 10), collect, and are placed on a memory body (memory) lining.This A/D conversion is a kind of lossy compression method, can cause the loss of sound details, sounds that with primary sound certain difference is arranged, and influences imitation and the understanding of user to primary sound;

4, the memory body of language repeater (memory) is generally very little, can only record tens seconds, when the sound of needs record is longer, usually needs branch several times, so also influences people's study.

These disadvantages affect of belt language repeater people's use.

Along with the development of mobile phone, increasing mobile phone has had the mp3 playing function.There is very large memory body (memory) the mobile phone the inside, can store tens first even first mp3 up to a hundred.Mp3 player tonequality is good, clear, and details is abundant, and is easy to use.The more important thing is that the mp3 wide material sources have a lot of mp3 music on the net, can download from the Internet.Sound on the cassette tape also can convert mp3 to easily.

So, utilize mobile phone to realize the function of mp3 language repeater, can solve the shortcoming of cassette tape formula language repeater easily.

Summary of the invention

The object of the present invention is to provide a kind of mobile phone with digital music repeating function.

Technical scheme of the present invention is as follows:

According to a kind of mobile phone of the present invention with digital music repeating function, comprise mobile phone base band chip, it is characterized in that to also have: one becomes the multimedia chip of two-way electrical coupling with this mobile phone base band chip, have mp3 playing function and management memory body, and output mp3 decoded signal; One becomes the audio process of two-way electrical coupling with this multimedia process chip, it is accepted the mp3 decoded signal and handles and output sound signal; One with the earphone or the loud speaker of the output electrical coupling of this audio process; And on the memory of mobile phone base band chip, store the mp3 data and set up mp3 loop play functional module and AB section playing function module, this two functional module is by the execution of the processor in the baseband chip and respectively by the startup of the loop play function key on the mobile phone faceplate with by A key, B key control.

Further, also be provided with mp3 data input port on this mobile phone, the mp3 data of accepting network download mp3 data or changing by cassette tape.

The present invention realizes following record function: mp3 loop play function and AB section playing function.

1, mp3 loop play function

In order further not hear the details of primary sound, people listen usually repeatedly.The loop play function has then made things convenient for these needs, as long as the user is set at " loop play " pattern, this equipment will ceaselessly be play so, till the user stops it.

2, AB section playing function

Under the loop play function, people can listen to a first mp3 primary sound repeatedly.But some the time, people just hope do not hear wherein certain in short, perhaps one of them word, repeat playing from the beginning to the end just seems and loses time.Set starting point (A point) and the terminal point (B point) play and seem necessary.AB section playing function has adapted to this demand.For example, the user thinks re-reading a word wherein, just when the broadcast of the words begins, is set to " A point "; During end, be set to " B point ".So, this device is voice between the re-reading A-B only just, voice that also can repeat playing AB section.

Positive effect of the present invention is integrated mp3 record function on mobile phone, has saved the cost of independent purchase language repeater greatly, and easy to carry, uses easily.Because the user carries mobile phone usually, this function can help the user to learn foreign languages whenever and wherever possible.The equipment cost of this scheme is low, and is convenient, and other functions of mobile phone are not almost influenced.

Description of drawings

Fig. 1 is the overall construction drawing of one embodiment of the invention.

Fig. 2 is the loop play functional flow diagram of one embodiment of the invention.

Embodiment

Provide the better embodiment of the present invention according to Fig. 1-Fig. 3 below, and described in detail, make those skilled in the art be easier to understand architectural feature of the present invention and functional characteristics, rather than limit scope of the present invention.

1, according to the design of Fig. 1, carry out the connection of circuit, wherein: multimedia chip 2, adopt the corelogic8238 cake core; Audio Processing chip 3 adopts the AK4642 cake core.

2, mp3 loop play function (flow chart is Fig. 2):

1, selects a first mp3 file;

2, be set to " loop play " mode;

3, begin to play;

4,, stop or withdrawing from broadcast when when not required.

3, AB section playing function (flow chart is Fig. 3),
