Digital hearing aid operating system updating device

Technical Field

The utility model belongs to the technical field of digital audiphone auxiliary assembly, a digital audiphone operating system updates device is related to.

Background

With the acceleration of modern society rhythm, the number of people suffering from hearing impairment of different degrees is increasing due to congenital physical defects or acquired environmental factors. The hearing impairment can damage the auditory and speech functions of people, affect the physical and mental health and increase the economic and social burden.

Hearing loss is mainly classified into conductive deafness, sensorineural deafness and mixed deafness according to the analysis of lesion damage parts. The conductive deafness is caused by the fact that the sound conduction process is obstructed due to the fact that the auricle is diseased in the outer ear. Sensorineural deafness refers to the failure of cochlear spiral organ lesion to change sound wave into nerve excitation or the failure of nerve and central pathway thereof to transmit nerve excitation; or central lesions of cerebral cortex, which cannot distinguish speech, is collectively called sensorineural deafness. Mixed deafness refers to the presence of lesions in both the sound-transmitting and sound-sensing mechanisms.

Hearing loss can be divided into four levels according to degree analysis. The hearing status of a patient is detected by giving sound signals with different hearing level HL (ISO standard hearing level) intensities at different frequency points of 500Hz, 1000Hz, 2000Hz and 4000Hz, a tested person can hear sound signals with the minimum intensity of 26-40dB (normal voice) within 1m, the sound signals belong to mild hearing loss, and the audible minimum sound intensity of 41-60dB (higher voice) belongs to moderate hearing loss; 61-80dB (yelling) belongs to severe hearing impairment; more than 80dB is attributed to profound hearing loss.

The operating system in the digital hearing aid needs to be adjusted correspondingly according to different people or different environments so as to adapt to hearing patients with different conditions and external environments with different conditions. However, the conventional digital hearing aid operating system still maintains the factory settings, and the functions thereof cannot be updated in time. This causes great inconvenience to the user. Therefore, a device for updating the operating system of the digital hearing aid is needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a digital audiphone operating system updates device has solved among the prior art problem that digital audiphone operating system can't be updated according to user and external environment at any time.

The utility model discloses the technical scheme who adopts is, and digital audiphone operating system updating device installs in digital audiphone, including DSP digital signal processing chip, FLASH memory and SDRAM memory are connected respectively to DSP digital signal processing chip, and bluetooth module is connected with DSP digital signal processing chip electricity.

And the DSP digital signal processing chip is in communication connection with all components of the original digital hearing aid.

The FLASH memory is divided into 5 storage areas from the LSB end to the MSB end, and the storage areas are a BootLoader area, a mirror image file storage area 1, a mirror image file storage area 2, an initial version storage area and a parameter configuration area in sequence.

The image file storage area 1 and the image file storage area 2 store program image files, respectively.

The parameter configuration area stores the solidified system configuration parameters.

The initial version storage area stores a system program of a factory-set version.

The SDRAM memory stores the program image file received by the Bluetooth module.

The Bluetooth module is in wireless connection with the smart phone and is connected with the Internet through the smart phone.

The utility model has the advantages that:

1. aiming at the problem that the hearing aid operating system cannot be updated in time, a user can update the operating system of the digital hearing aid through a mobile phone, so that the convenience of use of the user is greatly improved.

2. When the traditional hearing aid adjusts or updates the internal parameters of the hearing aid, a user needs to properly adjust or update the internal parameters of the hearing aid according to the change condition of the current condition of the user after a certain specified time period, which brings great inconvenience to the user; by using the device, the user only needs to pay attention to the system updating reminding and can independently complete the operation system updating of the digital hearing aid.

3. The manufacturer can continuously optimize the algorithm of the digital hearing aid along with the continuous research and development of the technology, the optimized program package can be directly uploaded to the official website, the user downloads the updated program package through the official website of the manufacturer to complete the updating of the system, and the manufacturer does not need to stipulate that the user finishes the updating of the system of the hearing aid to a designated place within a designated time, so that the efficiency of the manufacturer is greatly improved, and the workload of the manufacturer is reduced.
