[0036] see figure 1 , figure 1It is a structural schematic diagram of a tactile-assisted hearing-aid device disclosed in an embodiment of the present invention. The hearing-aid device is used to be worn on the user's head, including: a microphone 101, an analog-to-digital converter 102, a digital filter 103, and an amplifier 104 , digital-to-analog converter 105, player 106, database module 107, positioning module 108, microphone 109, analog-to-digital converter 110, digital filter 111, amplifier 112, digital-to-analog converter 113 and vibrator 114;
[0037] in,
[0038] The microphone 101 is connected with the analog-to-digital converter 102, and the sound pressure change of the air vibration is converted into a digital signal, which is input into the digital filter 103 and the positioning module 108 respectively; Converter 106 into an analog signal, played by the player 106 worn by the user as an audio signal.
[0039] The physical position of microphone 109 can be different from microphone 101, and microphone 109 is connected with analog-to-digital converter 110, and the sound pressure intensity change of air vibration is converted into a digital signal, which is input into digital filter 111 and positioning module 108 respectively; digital filter 111 outputs Filter the signal to the amplifier 112, and convert it into an analog signal by the digital-to-analog converter 113, and the vibrator 114 worn by the user provides a vibration signal to the user; it should be noted that the digital signal sent by the analog-to-digital converter 110 to the positioning module 108, The digital signal sent from the analog-to-digital converter 102 to the positioning module 108 is combined with the pre-stored data in the database module 107 for pattern matching.
[0040] In practical applications, the vibrator 114 can also be an electrical stimulation device.
[0041] Preferably, the present invention also includes any one or a combination of display screens and virtual reality devices. For example, the present invention can be added to virtual reality glasses. The virtual reality glasses can not only display the low-frequency and/or high-frequency characteristics of the sound signal to the wearing user, but also indicate the source of the sound to the wearing user, so as to pass the visual, auditory and vibration The combined effect assists patients in more effective verbal communication, thereby increasing communication speed and accuracy.
[0042] Preferably, there may be two or more vibrators 114, which are respectively placed at different positions on the head. For example, two vibrators are placed on the left temporal bone and the right temporal bone respectively, and the difference in the left and right low-frequency vibration amplitudes is used to remind the patient whether the source of the sound signal is left or right.
[0043] It should be noted that in practical applications, the positioning module 108 also stores the maximum safe stimulation intensity value of the stimulation signal, and can send the stimulation signal with the maximum safe stimulation intensity value to the amplifier 104 and the amplifier 112; When the playback intensity value exceeds the maximum safe stimulation intensity value, the positioning module 108 controls the amplifier 104 and the amplifier 112 to stimulate the wearing user according to the stimulation signal of the maximum safe stimulation intensity value.
[0044] In summary, the tactile-assisted hearing aid device disclosed in the present invention includes: a microphone 101, an analog-to-digital converter 102, a digital filter 103, an amplifier 104, a digital-to-analog converter 105, a player 106, a database module 107, and a positioning module 108 , microphone 109, analog-to-digital converter 110, digital filter 111, amplifier 112, digital-to-analog converter 113 and vibrator 114; by synchronously playing sound and providing vibration, it better meets the needs of the center for information and improves Central language recognition ability. Therefore, the present invention realizes the combination of the auditory stimulation pathway 115 and the tactile stimulation pathway 116, and improves the therapeutic effect on the user's hearing impairment.
[0045] Corresponding to the above embodiments, the present invention also discloses a tactile-aided hearing aid system.
[0046] see figure 2 , a structural diagram of a tactile-assisted hearing aid system disclosed in an embodiment of the present invention, the hearing aid system includes: a cloud server 117 and at least one hearing aid system in the above-mentioned embodiment, the hearing aid system can be figure 1 In the hearing aid device shown in , the cloud server 117 is connected with the positioning module 108 in the hearing aid device;
[0047] The cloud server 117 is used to receive the digital signal sent by the positioning module 108 and the case information of the wearing user, and use the artificial intelligence algorithm to deduce the optimal filtering parameters and the optimal amplification parameters for the digital signal and case information, and feed these parameters back to the positioning module 108 .
[0048] In practical applications, the artificial intelligence algorithm may be an artificial neural network algorithm, a genetic algorithm, a pattern recognition algorithm, a linear regression algorithm and/or a linear prediction algorithm.
[0049] The case information of the wearing user received by the cloud server 117 may include: audiogram, vowel recognition rate, consonant recognition rate, four-tonal tone recognition rate, sentence recognition rate, positioning resolution and/or the amount of mental health Tables such as the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders 5th Edition, International Classification of Psychiatric Behavior Disorders 10th Edition, Child and Adolescent Behavior Scale, Hamilton Anxiety Scale, Beck Depression Inventory, Sleep Disorders Scale table, the tinnitus disability scale of the American Tinnitus Association and/or the tinnitus function index; these case information quantitatively describe the condition of the patient's hearing and brain center; the cloud server 117 establishes the mapping relationship between the digital signal and the environmental noise scene by learning, for example Apartments, shopping malls, schools, office buildings, highways, fields, theaters, etc., and then establish a mapping relationship from specific environmental noise scenes and case information to optimal filtering parameters and amplification parameters; as the number of patients increases, the cloud server 117 can Based on this mapping relationship, individual treatment that varies from person to person and from scenario to scenario is realized, reducing unnecessary one-on-one doctor-patient treatment costs.
[0050] To sum up, in the tactile-assisted hearing aid system disclosed in the present invention, the cloud server 117 realizes the collection of individual information, optimizes it by using an artificial intelligence algorithm, and configures optimal filtering parameters and amplification parameters.
