Embodiment Construction

[0020] The invention provides a method and a device for realizing the hearing aid function in a mobile communication terminal (such as a mobile phone), which is applicable to 2.5th generation and 3rd generation mobile terminals such as GSM / GPRS, CDMA, WCDMA, and TD-SCDMA.

[0021] see figure 2 , which is a circuit connection diagram of the handset device in the mobile communication terminal of the present invention. As shown in the figure: it includes the main chip (CPU) and the receiver. The main chip (such as the baseband chip of CDMA2000) has two receiving signals that are directly output to the receiver (that is, the speaker). These two signals are generally called Receiver signals. , P, N are the pins of the two signals connected to the earpiece (P means positive, N means negative). A power amplifier (PA) module that can amplify the signal is connected between the main chip and the earpiece, and whether the power amplifier (PA) module is controlled by the CPU to amplify...

Abstract

This invention relates to mobile communication terminal phone device improvement and to one mobile communication terminal with hears aid function, which comprises Main chip and hear end and power amplifier module between above two to control whether to amplify the sound signal. When needing the use of hear aid function, it opens the main chip power amplifier module signal to be sent to the hear end. This invention mainly solves the current mobile communication terminal hear end volume adjusting range limited problem and the aid hear technique problem to facilitate hear obstacle people to use mobile communication product.

Description

Technical field: [0001] The invention relates to the improvement of the earpiece device of the mobile communication terminal, in particular to a mobile communication terminal with a hearing aid function and a method for realizing the hearing aid. Background technique: [0002] At present, the main chip (such as: the baseband chip of CDMA2000) of the communication module in the mobile communication terminal (such as: mobile phone) has two receiving signals that are directly output to the earpiece (ie, the loudspeaker). These two signals are generally called Receiver signals. Commonly used handset device connections see figure 1 , wherein, CPU is the control processing unit, P, N are the pins of the two signals connected to the handset (P means positive, N means negative). When in use, the volume of the earpiece can be adjusted within a limited range by means of buttons or the like. [0003] Judging from the current age distribution of mobile phone users, everyone from the e...
