Problems solved by technology

[0002] At present, mobile phone recording technology has been widely used, but its effect is not satisfactory
The existing recording and playback mobile phones have a relatively short recording and playback time, and few of them can exceed 3 minutes, which cannot meet the needs of users for longer time recording and playback.
In addition, many solutions need to add hardware devices to the mobile phone, which increases the cost of the mobile phone, and some solutions need to change or rewrite the existing software system, and the production process is poor.

Abstract

The handset is composed of a user module, a user interface, a system module, SIM card circuit, a user recognition module, a transmitting and receiving circuit, a mike and a headphone. The user interface for recording function includes also the key buttons for inputting the recording command and querying whether there is a storage space. The LCD displays the recording command and the queried results. The system module includes the digital signal processor, the flash memory interface, the flash memory manager. When there is no storage space, a recording procedure will not be processed. When there is a storage space, the digital signal processor converts the analog signal from the headphone through A / D converter to the digital signal and coded as a data package. The invented handset realizes the function of recording and playing back sound without need of adding hardware.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and more specifically relates to the improvement of a CDMA mobile phone with voice recording and playback functions. Background technique [0002] At present, mobile phone recording technology has been widely used, but its effect is not satisfactory. The recording and playback time of the existing recording and playback mobile phones is relatively short, and rarely exceeds 3 minutes, which cannot satisfy the user's long-time recording and playback needs. In addition, many solutions need to add hardware devices to the mobile phone, which increases the cost of the mobile phone, and some solutions need to change or rewrite the existing software system, and the production process is poor. [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and deficiencies, and provide a mobile phone that does not need to increase hardware and production costs, ...
