Detailed Description
In order to more clearly express the present invention, the present invention will be further described below with reference to the invention and examples.
Referring to fig. 1, the present application discloses a one-to-two bone conduction hearing aid method, comprising the steps of:
s1, the sound pick-up searches two bone conduction earphones which can be connected wirelessly, and a connection secret key is arranged in the bone conduction earphones;
s2, the sound pick-up sends a first request instruction for connecting with the first bone conduction earphone;

s7: the second bone conduction earphone feeds the second PDM back to the sound pickup to realize the binding between the second bone conduction earphone and the sound pickup;
s8: the sound pick-up sends audio signals to the two bone conduction earphones, and audio playing is achieved.
In a specific embodiment, through the eight steps, the two bone conduction earphones can be connected in a matched mode through one sound pick-up, so that the data transmission time of the two bone conduction earphones is shortened, and the delay is reduced; every bone conduction earphone all has the unique connection key of oneself, and after pairing, guarantee that the adapter can accurately carry out the information interaction with the bone conduction earphone that corresponds like this, the confusion of information can not appear.
In order to achieve the above object, after step S4, the method further includes: the sound pick-up stores the PDM corresponding to the generation of the bone conduction earphone so as to be directly bound with the bone conduction earphone when being connected with the sound pick-up next time; in step S5, the second request instruction includes the first request instruction and the first PDM, and after the second request instruction is received by the second bone conduction headset and matched, the first PDM is included in the generated second PDM. In this embodiment, after the bone conduction headset is paired with the sound pickup, the PDM composed of the connection key and the matching information of the bone conduction headset is stored in the sound pickup, and when the sound pickup is started next time, the stored bone conduction headset is preferentially connected, and if the stored bone conduction headset needs to be replaced or deleted, the stored bone conduction headset is erased or re-adapted on the sound pickup.
For the hearing-impaired people, the external form of the expression is that the exact sound cannot be heard, but actually, many patients go to the hospital to detect, the result is not auditory nerve damage, but eardrum damage, and the sound of a certain frequency band does not correspond, for example, the frequency band of 150-: and analyzing the acquired audio signal, performing gain compensation to obtain a gain compensation audio segment, and transmitting the gain compensation audio to the two bone conduction earphones through the audio transmission link for playing. The audio segment is compensated by the gain so that the user can hear the clearest sound.
The audio transmission link comprises: sequencing each communication signal according to the time of the accessed communication signal, establishing audio transmission links one by one through one or more of a WiFi protocol, a 2.4G communication protocol, an A2DP protocol and a Bluetooth protocol according to the sequencing result, and establishing a corresponding relation between each audio transmission link and the corresponding communication signal; after the relationship is established, numbering of each audio transmission link is also included. In this embodiment, the bluetooth protocol is the AptX-II protocol. aptX is a digital audio compression algorithm based on the sub-band ADPCM (SB-ADPCM) technique. The original algorithm was proposed by doctor Stephen Smyth in the 80's of the 20 th century. Developed by Audio Processing Technology (now incorporated by CSR) and named AptX. Originally used in the professional audio and broadcast fields. In recent years, AptX in the field of Bluetooth wireless audio transmission has a great potential to replace SBC (Sub-band Coding) due to its advantages of low latency, good fault tolerance, high sound quality, etc., and its delay can reach 40ms or less, which is less than the delay time that can be felt by human beings, because when two sounds with equal intensities and one delayed sound comes into the listener's ear at the same time, if the delay is within 30ms, the sound will be felt aurally as if it is only from the undelayed sound source, and the delayed sound source will not be felt to exist. When the delay time exceeds 30ms and does not reach 50ms, it is audibly recognized that a delayed sound source exists, but the sound is perceived as coming from an undelayed sound source. Only after a delay time of more than 50ms is the delayed sound acoustically perceived as a clear echo. This phenomenon is called the haas effect and sometimes called the precedence effect, so that the wireless communication using AptX-ll greatly reduces the time delay, and makes the user more natural and closer to the normal ac receiving speed during the ac communication.
The step of analyzing the audio signal and performing gain compensation to obtain a gain compensation audio segment comprises: receiving a switching command of at least one bone conduction earphone, and pairing the switching command with an audio transmission link according to the corresponding relation between the audio transmission link and a communication signal; analyzing the audio signal according to each switching command and carrying out gain compensation to obtain a gain compensation audio segment of each switching command; the corresponding gain audio segment is transmitted to the corresponding bone conduction headset over the audio transmission link corresponding to each switching command. The analyzing the audio signal according to each switching command and performing gain compensation to obtain a gain compensation audio segment of each switching command comprises: filtering and converting the external audio signal according to each switching command, and filtering the external audio signal through filtering and converting to obtain a non-target frequency band and a target frequency band of each switching command; and after filtering and transforming the external audio signals under all the switching commands, rejecting the non-target frequency bands, and performing band gain on the target frequency bands of all the switching commands to obtain the gain audio signals of each switching command. In this embodiment, in order to enable a user to use the mobile phone, for example, the user needs to focus on amplifying sound of a specific channel and completely filter out other sound, or the user needs to listen to music on a mobile phone, if the mobile phone is a common headset, for people with hearing impairment, the sound of the headset needs to be adjusted to the maximum to be clearly heard, but the common headset does not have a function of selecting sound, and amplifies signals of all audio frequencies at the same time, and the volume at the time exceeds the normal size, so that people can feel irritated when the mobile phone is in such an environment for a long time, and further hurt the eardrum which is damaged, and when the mobile phone directly transmits sound of music or television to the outside, the mobile phone interferes with the outside, so that key sound source information can be effectively obtained from a plurality of sound sources, and gain is carried out on the key sound source, so that the information is not lost in the transmission process.
Naturally, before step S8, the method further includes obtaining audio signals, where the obtaining includes obtaining a data line and obtaining wirelessly, and when there is an audio device connected to the data line and the USB interface, only receiving the audio signal output by the audio device, shielding other audio signals except the audio device, defining the audio signal as a first audio signal, and performing gain compensation on the first audio signal after analyzing the first audio signal to obtain a gain-compensated audio segment; and when no audio equipment is accessed to the data line and the universal serial bus USB interface, determining the audio equipment to be wirelessly acquired, defining the audio equipment to be a second audio signal, analyzing the second audio signal, and performing gain compensation on the second audio signal to obtain a gain compensation audio section. In this embodiment, the adapter is according to whether external device to the acquirement to the sound source is chosen the choice, thereby guarantees to carry out gain compensation to the sound source of effectively acquireing.
The invention is illustrated in the following by specific embodiments:
the bone conduction headset is provided with a first pairing module, a second pairing module, a main control module and a storage module, the bone conduction headset is provided with a connecting module and a debugging module, when pairing is needed, the main control module on the sound pick-up controls the first pairing module to send a pairing request instruction to one of the bone conduction headsets, the bone conduction headset generates a first PDM (product data management) in the connecting module after receiving the pairing request instruction and a connection key of the bone conduction headset, the first PDM is fed back to the sound pick-up, the sound pick-up stores the first PDM, and pairing connection is established between the first PDM and the sound pick-up; when the bone conduction headset needs to be paired with a second bone conduction headset, the main control module is paired with the second bone conduction headset by using the second pairing module, a pairing request instruction with the first PDM is sent to the second bone conduction headset, and then the second bone conduction headset receives the pairing request instruction and generates a second PDM to feed back the second PDM to the main control module of the sound pick-up; the main control module carries out gain compensation on the acquired audio, and the bone conduction earphone end is selectively debugged and switched by adopting the debugging module, so that the sound is clearer.
