Description

Technical Field

[0001] The present invention relates to the field of hearing aids, and in particular to a multi-power source hearing aid system with an anti-lost function. Background Art

[0002] Hearing impairment is a global health problem. With the aging of the population, the increase in noise pollution and the impact of some diseases, the number of people with hearing loss continues to rise. Hearing aids are essential tools for people with hearing impairment. A large proportion of users who need hearing aids are elderly people. Hearing aids are small in size and easy to lose and difficult to find for the elderly. Traditional hearing aids with certain anti-lost functions mainly use Bluetooth signals to scan and search for devices, which have disadvantages such as unstable signals and high power consumption. Therefore, it is particularly important to invent a multi-power hearing aid system with anti-lost function.

[0003] Prior art, such as the invention application patent with announcement number: CN115334436A, discloses an anti-lost hearing aid with a positioning function, comprising a hearing aid body, a connector is arranged on the outside of the hearing aid body, an earplug is installed on the end of the connector away from the hearing aid body, a positioning groove is provided on one side of the hearing aid body, a drop protection component is movably arranged inside the positioning groove, a signal transmitter is also installed inside the positioning groove, and an embedded processor for processing information is installed inside the hearing aid body; a placement groove is provided on the other side of the hearing aid body, a plurality of adjustment rods are movably arranged inside the placement groove, when the protective plate is rotated outward, the signal transmitter starts to work, and a positioning signal of the hearing aid is sent through the signal transmitter, and the two protective plates are rotated outward at the same time to form an arc shape, so as to enhance the intensity of the position signal transmission and realize the positioning of the lost hearing aid.

[0004] The prior art also has the following defects, which are specifically reflected in:

[0005] 1. In the prior art, little attention has been paid to hearing aid anti-lost function. Most existing hearing aids with anti-lost function use Bluetooth signals to scan signals, which have problems such as limited signal range, susceptibility to interference from environmental factors, and high power consumption. In the process of finding the hearing aid, the difficulty of finding the hearing aid is increased, thereby reducing the probability of finding the hearing aid and causing property loss.

[0006] 2. In the prior art, little attention has been paid to the power supply for hearing aid anti-loss protection, and signal generation is restricted. Insufficient power reduces the working time of the anti-loss system. Insufficient power will cause the signal transmission power to decrease or fail to transmit signals. The hearing aid cannot provide users with positioning guidance such as sound and flashing lights, which increases the difficulty of finding the hearing aid and the probability of losing the hearing aid. The loss of the hearing aid increases the danger to the user. Summary of the invention

[0007] The purpose of the present invention is to provide a multi-power hearing aid system with an anti-lost function, which solves the problems existing in the background technology.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a multi-power hearing aid system with anti-lost function, including: a hearing aid hearing unit, a hearing aid anti-lost unit and an external UHF scanner.

[0009] The hearing aid unit comprises a hearing aid wearing detection module and a lithium battery power supply management module.

[0010] The hearing aid wearing detection module is used to detect the wearing status of the hearing aid, and based on the wearing status of the hearing aid, determine whether the hearing aid is lost. If the hearing aid is lost, start the anti-lost unit, obtain the external environmental parameters of the hearing aid, and analyze the impact of the external environmental parameters of the hearing aid on the sound frequency and light flashing frequency of the entire hearing aid.

[0011] The lithium battery power supply management module is used to obtain the remaining power of the micro solid-state battery, determine whether the lithium battery needs to supply power to the micro solid-state battery, and supply power to the micro solid-state battery.

[0012] The hearing aid anti-loss unit includes a UHF anti-loss function module and a micro solid-state battery charging management module.

[0013] The UHF anti-loss function module adjusts the sound frequency, light flashing frequency and UHF ultra-high frequency transmission frequency of the hearing aid based on the external environmental parameters of the hearing aid and the remaining power of the micro solid-state battery.

[0014] The micro solid-state battery charging management module is used to power the hearing aid anti-loss unit.

[0015] The external UHF scanner is used to scan and read UHF ultra-high frequency radio frequency identification signals to search for lost hearing aids.

[0016] Preferably, the specific analysis method for determining whether the hearing aid is lost is: obtaining the pressure value generated by each hearing aid wearing detection, and comparing it with the preset hearing aid wearing pressure value range; if the pressure value generated by a hearing aid wearing detection is within the preset hearing aid wearing pressure value range, then this detection is recorded as a normal detection, and each normal detection is obtained, and the total number of detections and the total number of normal detections are statistically obtained, and the total number of normal detections is divided by the total number of detections to obtain the normal wearing rate of the hearing aid, which is compared with the preset hearing aid wearing accuracy rate; if the normal wearing accuracy rate of the hearing aid is lower than the preset hearing aid wearing accuracy rate, then it is determined that the hearing aid is lost; otherwise, it is determined that the hearing aid is not lost.

[0017] Preferably, the analysis of the influence of the external environment parameters of the hearing aid on the sound frequency and light flashing frequency of the entire hearing aid is specifically performed by the following analysis method: extracting the external environment parameters of the hearing aid, evaluating the hazard coefficient of the external environment of the hearing aid, extracting the minimum value of the sound decibels of the external environment of the hearing aid for each set time period, and comparing it with the preset hearing aid lost search sound decibels; if the minimum value of the sound decibels of the external environment of the hearing aid for a set time period is higher than the preset hearing aid lost search sound decibels, the hearing aid does not make a sound, and it is determined that the sound function of the hearing aid is turned off; otherwise, it is determined that the sound function of the hearing aid is turned on, obtaining the sound decibel values ​​of the external environment of the hearing aid at each monitoring time point, evaluating the sound change rate of the external environment of the hearing aid, analyzing the sound change trend of the external environment of the hearing aid, and adjusting the frequency of the sound emitted by the hearing aid based on the remaining power of the micro solid-state battery.

[0018] Extract the minimum value of the light intensity of the hearing aid's external environment for each set time period, and compare it with the preset hearing aid lost search light intensity. If the minimum value of the light intensity of the hearing aid's external environment for a set time period is higher than the preset hearing aid lost search light intensity, the hearing aid will not emit light flashing, and it is determined that the hearing aid's light flashing function is turned off. Otherwise, it is determined that the hearing aid's light flashing function is turned on. Obtain the light intensity of the hearing aid's external environment at each monitoring time point, evaluate the light intensity change rate of the hearing aid's external environment, analyze the light intensity change trend of the hearing aid's external environment, and adjust the frequency of the hearing aid's light flashing based on the remaining power of the micro solid-state battery.

[0019] Preferably, the evaluation of the hearing aid external environment hazard coefficient is specifically analyzed by extracting the temperature and humidity of the hearing aid external environment at each monitoring time point, evaluating the hearing aid external environment hazard coefficient, and the calculation formula is: ,in Indicates the external environmental hazard factor of the hearing aid. , They represent the temperature and humidity of the external environment of the hearing aid at the i-th monitoring time point, , They represent the middle value of the hearing aid's suitable working temperature range and humidity range respectively. , They respectively represent the impact factors of temperature and humidity on the operation of hearing aids, i represents the number of each monitoring time point, j represents the number of monitoring time points, and e represents a natural constant.

[0020] Preferably, the specific analysis method for evaluating the sound change rate of the external environment of the hearing aid is: extracting the sound decibel value of the external environment of the hearing aid at each monitoring time point, evaluating the sound change rate of the external environment of the hearing aid, and calculating the formula is: , where k represents the rate of change of sound in the external environment of the hearing aid, represents the sound decibel value of the hearing aid's external environment at the i-th monitoring time point, Indicates the external environment of the hearing aid The sound decibel value at each monitoring time point.

[0021] Preferably, the analysis of the sound change trend of the external environment of the hearing aid comprises: extracting the sound change rate of the external environment of the hearing aid, and comparing it with a preset sound change rate of the external environment of the hearing aid; if the sound change rate of the external environment of the hearing aid is higher than the preset sound change rate of the external environment of the hearing aid, it indicates that the sound change trend of the external environment of the hearing aid is that the sound gradually becomes higher;

[0022] If the sound change rate of the external environment of the hearing aid is lower than the preset sound change rate of the external environment of the hearing aid, it indicates that the sound change trend of the external environment of the hearing aid is that the sound gradually becomes lower;

[0023] If the sound change rate of the external environment of the hearing aid is equal to the preset sound change rate of the external environment of the hearing aid, it indicates that the sound of the external environment of the hearing aid does not change;

[0024] To summarize, the analysis of the sound change trend of the hearing aid's external environment is gradually getting higher, gradually getting lower, or not changing.

[0025] Preferably, the frequency of adjusting the sound emitted by the hearing aid is specifically analyzed by the following method: extracting the remaining power of the micro solid-state battery at each monitoring time point, obtaining the power level of the remaining power of the micro solid-state battery at each monitoring time point, if the power level of the remaining power of the micro solid-state battery at a certain monitoring time point is level one, then the frequency of the sound emitted by the hearing aid is the frequency of the initial sound emitted, if the power level of the remaining power of the micro solid-state battery at a certain monitoring time point is level two, then the frequency of the sound emitted by the hearing aid is the frequency of the level two sound emitted, if the power level of the remaining power of the micro solid-state battery at a certain monitoring time point is level three, then the frequency of the sound emitted by the hearing aid is the frequency of the level three sound emitted;

[0026] Extract the sound change trend of the hearing aid's external environment. If the sound change trend of the hearing aid's external environment is that the sound gradually becomes higher, then extract the frequency level of the sound emitted by the hearing aid, and automatically lower the frequency level of the sound emitted by the hearing aid to the next level of the current frequency level of the sound emitted by the hearing aid. If the sound change trend of the hearing aid's external environment is that the sound gradually becomes lower, then automatically raise the frequency level of the sound emitted by the hearing aid to the next level of the current frequency level of the sound emitted by the hearing aid. If the sound of the hearing aid's external environment does not change, the frequency of the sound emitted by the hearing aid remains unchanged.

[0027] Preferably, the judgment of whether the lithium battery needs to power the micro solid-state battery is based on a specific analysis method: extracting the remaining power of the micro solid-state battery at each monitoring time point, and comparing it with a preset safety remaining power threshold; if the remaining power of the micro solid-state battery at the current monitoring time point is higher than the preset safety remaining power threshold, then it is determined that the lithium battery does not need to power the micro solid-state battery; if the remaining power of the micro solid-state battery at the current monitoring time point is lower than the preset safety remaining power threshold, then it is determined that the lithium battery needs to power the micro solid-state battery.

[0028] Preferably, the specific analysis method for searching for the lost hearing aid is: use an external UHF scanner to scan the UHF ultra-high frequency radio frequency identification signal of the hearing aid; if the external UHF scanner recognizes the UHF ultra-high frequency radio frequency identification signal of the hearing aid, it is determined that the hearing aid is within the range of the external UHF scanner, and the frequency of the sound emitted by the hearing aid, the frequency of the flashing light and the UHF ultra-high frequency transmission frequency are all the frequencies of the initial sound emitted; conversely, if the external UHF scanner does not recognize the UHF ultra-high frequency radio frequency identification signal of the hearing aid, it is determined that the hearing aid is outside the range of the external UHF scanner.

[0029] The second aspect of the present invention also includes a database, specifically including: a preset hearing aid wearing pressure value range, a preset hearing aid lost search sound decibel, a preset hearing aid lost search light intensity, a hearing aid suitable working temperature range, a humidity range, a preset sound change rate of the hearing aid external environment, a micro solid-state battery's remaining power level and different corresponding hearing aid loss indication frequencies, and a preset safety remaining power threshold.

[0030] The beneficial effects of the present invention are:

[0031] 1. In the present invention, an independent anti-lost function is added to the design of the hearing aid. The anti-lost function uses UHF ultra-high frequency radio frequency identification signals to transmit lost signals. An external UHF scanner can be used to scan and search over a large area. Benefiting from the UHF ultra-high frequency radio frequency identification signal, the scanning and searching distance of the anti-lost system is greatly improved compared to Bluetooth, which reduces the difficulty of finding the hearing aid and the probability of losing the hearing aid.

[0032] 2. In the present invention, an independent anti-lost power supply system is added. The ultra-small size of the micro solid-state battery can be used inside the hearing aid to power the low-power anti-lost system. The power supply is triggered only when the hearing aid has not been used normally for a long time, thereby ensuring the short-term power supply of the anti-lost system, isolating the discharge from the power supply system of the hearing aid itself, and maintaining the charging monitoring of the micro solid-state battery by the hearing aid power supply system. By utilizing the advantages of multi-power supply switching, the working time of the anti-lost system is extended, the probability of finding the hearing aid is increased, and the danger to the user is reduced.
