Electronic cochlear in-vitro debugging platform based on local area network (LAN)

Abstract

The invention discloses an electronic cochlear debugging platform based on a local area network (LAN), and belongs to the technical field of electronic cochlear implantation. The electronic cochlear debugging platform is characterized by comprising person computer (PC) end electronic cochlear algorithm experimental platform software, an embedded processor module, an audio module, a modulation and power amplification module and a wireless transmitting coil. The PC end electronic cochlear algorithm experimental platform software is mainly used for controlling an electronic cochlear working mode and working parameters and carrying out data communication with the embedded processor module in a form of LAN communication; the embedded processor module comprises a low power consumption dual-core processor OMAP-L137 containing a digital signal processor (DSP) and an accumulator read-in module (ARM) and a protective circuit; the audio unit comprises an audio decoder-coder, a sound acquisition interface connected with a microphone, and an earphone output interface; the modulation and power amplification module comprises a baseband signal generating circuit, an amplifying and filtering circuit, a modulation circuit and a power amplifying circuit; and the wireless transmitting coil is mainly used for being coupled with an electronic cochlear implant and transmitting data and energy. The electronic cochlear debugging platform can be used for development and research of parameter debugging and new algorithms.

Description

technical field [0001] The invention belongs to the technical field of electronics, computer and signal processing, and in particular relates to an electronic cochlear external debugging platform device in electronic cochlear implantation. Background technique [0002] Cochlear implants, also known as cochlear implants, are currently the only devices that can restore hearing to totally deaf patients. It stimulates the residual auditory nerve in the cochlea of ​​the deaf by converting the sound signal into a weak current pulse, imitating the function of the peripheral auditory system, and making the patient produce nerve firing similar to that of the normal human ear. However, different cochlear implant recipients have very different survival conditions of their auditory nerves. In order to maximize the hearing effect of the cochlear implant recipient, it is necessary to tailor the working parameters of the external speech processor according to the residual condition of the...
