Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
When in use, earphone protrudes into ear canal hearing aid, and the sound that loudspeaker issue will not be spread to outside, therefore will not be passed
When entering in Mike, and earphone taking-up being stopped using, for the sound dispersion that loudspeaker issue into ambient enviroment, Mike can collect loudspeaker
The sound of sending, utters long and high-pitched sounds, the embodiment of the present invention is started by the whether pleasant control Mike of test earphone and loudspeaker to generate
With stop working, so that the sound that loudspeaker issue is reached to generate in Mike and be uttered long and high-pitched sounds when preventing earphone from taking out ear canal.
Based on this, the embodiment of the present invention provides a kind of hearing aid and enters ear detection method, referring to Fig. 1, this method comprises:
S100: transmitting detection optical signal, the detection optical signal have the first signal strength.
Specifically, a luminescent device is set in hearing aid, detection light signal, the detection optical signal are emitted to outside hearing aid
Encountering object barrier can reflect, and detection optical signal has the first signal strength.
S200: the reflection signal of the acquisition detection optical signal, the reflection signal have second signal intensity.
Specifically, reflection signal is acquired by setting sampler, reflection signal has second signal intensity, works as detection light
The intensity that signal encounters the reflection signal that object barrier generates is generally less than the intensity for detecting optical signal.
S300: judge whether the hearing aid is pleasant according to first signal strength and the second signal intensity.
Processor is set, and processor determines whether hearing aid enters by the first signal strength of comparison and second signal intensity
Ear, to control hearing aid movement.
Specifically, S310: judge whether the second signal intensity is greater than first signal strength.If so, determining
The hearing aid is pleasant.
If it is determined that hearing aid is pleasant, then S400: controls the hearing aid acquisition and play sound.
When determining that hearing aid is pleasant state, then processor controls the acquisition sound in hearing aid and plays the device of sound
It starts to work, acquires the device such as Mike of sound, play the device such as loudspeaker of sound.
If it is determined that hearing aid does not have pleasant, then S500: controlling the hearing aid and stop acquisition and play sound.
When determining that it is pleasant that hearing aid does not have, then the device of the acquisition sound in processor control hearing aid and broadcasting sound stops
It only works, generates and utter long and high-pitched sounds in the device of the incoming acquisition sound of the sound for preventing the device for playing sound from playing.
In addition, in another embodiment of the present invention, referring to fig. 2, it is contemplated that in some cases, the detection light of sending
Signal can reduce intensity by the Absorption of Medium such as wet air or glass a part, cause after launching hearing aid
Second signal intensity is less than the first signal strength, if determining at this time, hearing aid is pleasant, can generate erroneous judgement, therefore, in order into one
Whether step confirmation hearing aid is pleasant, prevents from judging by accident, then S311: judging whether the second signal intensity is greater than preset strength.
Between determining that second signal intensity is greater than the first signal strength and determines that hearing aid is pleasant, judge that second signal is strong
Whether degree is greater than preset strength, and the value of preset strength is believed according to the reflection that closely reflection detects signal of test of many times human skin
Number intensity be configured, in use, reflection signal, i.e., second signal intensity be greater than the preset strength when, just judgement hearing aid
It is pleasant, it avoids judging by accident.
In addition, referring to Fig. 3, in yet another embodiment of the present invention, S210: by the detection optical signal and the reflection
Signal is converted to level signal, and the detection optical signal has the first level value, and the reflection signal has second electrical level value.
S320: judge whether the hearing aid is pleasant according to first level value and the second electrical level value.
Will test optical signal and reflect the intensity of signal and characterized with the height of level, convenient for the processor in hearing aid according to
The height of level is quickly reacted, and is started or stopped hearing aid acquisition and is played sound.
Similarly, in order to avoid erroneous judgement, then S321: judging whether the second electrical level value is greater than predetermined level value, if so,
Determine that the hearing aid is pleasant.
Correspondingly, the embodiment of the present invention also provides a kind of hearing aid, which includes In-Ear Headphones, in the earphone
Loudspeaker and mainboard be set, the mainboard setting MCU and with MCU Mike be electrically connected and pleasant detection module, close institute
The ear that enters for stating earphone opens up aperture, and the aperture is arranged an optical filter and seals, and optical transceiver module is arranged on the inside of the optical filter,
The optical transceiver module is electrically connected by pinboard with mainboard；
The optical transceiver module is used to emit detection optical signal and acquires the reflection signal of the detection optical signal, the inspection
Light signal has the first signal strength, and the reflection signal has second signal intensity；
The pleasant detection module is used to help according to first signal strength and second signal intensity judgement
Listen device whether pleasant；
If so, the MCU, which controls the Mike, acquires sound, and the control loudspeaker play sound, if it is not, then institute
It states MCU and controls Mike's stopping acquisition sound, and the control loudspeaker stop playing sound.
In addition, the mainboard is additionally provided with photoelectric conversion module, the photoelectric conversion module is for believing the detection light
Number and the reflection signal be converted to level signal, the detection optical signal has with the first level value, the reflection signal
Second electrical level value.
Whether the pleasant detection module judges the hearing aid according to first level value and the second electrical level value
It is pleasant.
Specifically, show referring to fig. 4 with Fig. 5, the structural block diagram and structure of hearing aid respectively provided in an embodiment of the present invention
It is intended to, in one embodiment of the invention, hearing aid is wireless hearing aids, and hearing aid is powered entirely through battery 11, hearing aid
Device includes In-Ear Headphones, and dynamic iron loudspeaker 1 and mainboard 2, the wheat that mainboard 2 is arranged MCU3 and is electrically connected with MCU3 are arranged in earphone
Grams 4 and pleasant detection module 5, the ear that enters close to earphone open up the aperture 6 that a diameter is 2mm, an optical filter is arranged in aperture 6
Optical transceiver module 9 is arranged in 7 sealings on the inside of optical filter 7, and optical transceiver module 9 is electrically connected by pinboard 8 with mainboard 2, and is close to
