Problems solved by technology

[0004] However, most hearing-aid mobile phones currently on the market add analog lines inside the mobile phone to amplify the analog signal and output it. Some hearing-aid mobile phones even amplify the sound received by the mobile phone and output it. The output sound is prone to distortion and noise. Large, poor overall hearing aid performance

[0043] Please refer to figure 2 , the hearing-aid mobile phone in this embodiment includes components such as a mobile phone baseband chip, a microphone, and a hearing-aid earphone. Among them, the hearing aid earphones can be ordinary wired earphones or bluetooth earphones, and the baseband chip of the mobile phone is used as a device for implementing the hearing aid function of the mobile phone, mainly including a hearing aid function enabling module and an audio processing part.

[0044]A hearing aid button can be set on the hearing aid mobile phone, or a hearing aid option can be set on the user interface. When the user presses the hearing aid button or selects the hearing aid option, the hearing aid mobile phone can transmit and receive the hearing aid function to the hearing aid function opening module Turn on the command, informing it to start at least one of the following functions to start the hearing aid of the mobile phone according to the hearing aid function open...

Embodiment 2

[0055] The hearing aid mobile phone in this embodiment utilizes the baseband chip of the mobile phone to realize the hearing aid functions of call sound signals, radio sound signals, multimedia sound signals, ringtone signals, and game sound signals.

[0056] Such as Figure 5 As shown, the radio function and multimedia playback function of most mobile phones are integrated in the mobile phone baseband chip. The audio processing part of the mobile phone baseband chip can process radio sound signals (including FM sound signals and AM sound signals), multimedia sound signals (including Play sound signals in music formats such as MP3, and sound signals when playing videos), ringtone signals, game sound signals, etc. for audio processing. The audio processing methods include amplification, digital filtering, and D / A conversion. The process of digital filtering It is realized by an FIR (finite impulse response) digital filter and / or an IIR (Infinite Impulse Response: infinite impul...

Embodiment 3

[0060] Such as Figure 6 As shown, the hearing-aid mobile phone in this embodiment combines a professional digital hearing-aid chip with a mobile phone baseband chip to perform further digital audio processing on the sound signal to enhance the hearing-aid effect and adapt to the needs of hearing-impaired people with severe hearing loss. Hearing aid requirements.

[0061] The digital hearing-aid chip of this embodiment is connected to the baseband chip of the mobile phone. Specifically, the digital hearing-aid chip is connected between the microphone and the baseband chip of the mobile phone, and is used for performing A / D conversion, amplifying, and multiplexing the ambient sound signal picked up by the microphone. After digital audio processing in various ways such as channel filtering, echo suppression, and gain control, it is input to the sending branch of the mobile phone baseband chip for preprocessing. The PCM digital audio interface of the digital hearing aid chip is ...

Abstract

The invention discloses a method and a device for implementation of a hearing-aid function of a mobile phone and a hearing-aid mobile phone. The method includes the steps: after a mobile phone baseband chip receives a hearing-aid function opening instruction, opening at least one of the following functions according to the hearing-aid function opening instruction: a voice pickup function of a microphone, a voice output function of a hearing-aid earphone and a hearing-aid function of a sidetone branch in the mobile phone baseband chip; inputting environmental voice signals picked up by the microphone into a transmission branch of the mobile phone baseband chip, and preprocessing the environmental voice signals in the transmission branch; returning the preprocessed environmental voice signals to a receiving branch of the mobile phone baseband chip via the sidetone branch; performing audio processing for the environmental voice signals in the receiving branch; and outputting the environmental voice signals subjected to audio processing to the hearing-aid earphone. The hearing-aid function of the mobile phone is achieved by the aid of the mobile phone baseband chip, high-quality hearing-aid effects are provided, and the hearing-aid mobile phone is convenient to carry and lower in cost.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a method and device for realizing a hearing aid function, and a hearing aid mobile phone. Background technique [0002] Hearing aids are generally divided into analog hearing aids and digital hearing aids. The analog hearing aid uses a linear amplification circuit to amplify the analog audio signal. The structure is simple and the price is cheap, but the hearing aid effect is poor. digital hearing aids figure 1 The digital hearing aid chip shown in the figure performs noise reduction, filtering, automatic gain control and frequency compensation on the digital audio signal. For example, in a digital hearing aid, the digital hearing aid chip amplifies the analog signal of ambient sound picked up by the microphone through the amplifier , converted into a digital signal by the A / D conversion unit, and then input the digital signal into the audio filter unit sequent...
