Abstract
The utility model provides an IP telephone with the hearing-aid function. A speech processing module is additionally arranged on an output path of a handle loudspeaker of the IP telephone and has the volume amplification and frequency response adjusting functions. The IP telephone can be controlled by a main processing module to enter a normal mode or a baryacusis mode; if a user selects the baryacusis mode, the speech processing module works, and the user can automatically adjust the amplification times and the frequency response adjusting scope through a resistance regulator; if the normal mode is selected, speech signals directly skip the speech processing module and are directly output to the handle loudspeaker. The IP telephone is low in manufacturing cost, can cover wide user groups, and is good news for the majority of baryacusis patients.
