Embodiment Construction

[0019] Describe in detail below in conjunction with accompanying drawing.

[0020] Such as figure 1 As shown, the present embodiment is based on TMS320VC5509A and TLV320AIC23B cochlear external voice processing platform including six parts: digital signal processor (DSP) 1, audio codec 3, power supply circuit 6, USB interface 8, FLASH memory 2 and RF module 5. The core is a digital signal processor (DSP) 1, an externally expanded audio interface 3, a radio frequency interface 5, an external memory 2, a computer interface 8, a power supply circuit 6 and a control circuit 4 of the system. The following describes the implementation methods of each part.

[0021] Considering other factors such as system structure, task processing calculation amount and power consumption, DSP1 of the present invention adopts the TMS320VC5509A digital signal processor of TI Company, and TMS320VC5509A is a low-power consumption processor newly released by TI, and is particularly suitable for portab...

Abstract

The invention relates to an electric cochlear external voice treatment device, comprising microprocessor and power circuit. The input end of microprocessor is connected to acoustic frequency interface, output end is connected to radio frequency mode; said microprocessor employs digital signal processor TMS320VC5509A, the acoustic frequency interface employs TLV320AIC23B, the digital signal processor is connected with acoustic frequency interface through interface of I2C and MCBSP, the digital signal processor TMS320VC5509A is outer connected with FLASH memory, said FLASH memory stores systematic program for electric cochlear external voice treatment device. The kernel processor employs TMS320VC5509A, which increases system computing ability and reduces power consumption. The employed single chip acoustic frequency decoder accomplishes functions of enlargement, resisting aliasing filtering and AD sampling, which simplifies hard construction for whole flat base and reduces cost in further.

Description

technical field [0001] The invention relates to an electronic cochlea, in particular to an external voice processing device in the electronic cochlea, which collects and processes external voice signals and sends the processed signal to the implanted part of the electronic cochlea. Background technique [0002] The electronic cochlea is a high-tech electronic device that can completely replace damaged inner ear hair cells. It converts external sounds into nerve electrical impulse signals, bypasses the necrotic hair cells in the auditory system, and directly stimulates the spiral nerve of the auditory nerve. The section transmits information to the brain, allowing deaf patients to regain hearing. [0003] Cochlear electronics can be divided into two parts in terms of hardware structure, namely the speech processing platform outside the body and the implanted part inside the body. The function of the in vitro speech processing platform is to pick up the speech signal from the...
