Fig. 1 shows a control method of a hearing aid bluetooth headset according to an embodiment of the present invention.
As shown in fig. 1, the method for controlling a hearing aid bluetooth headset comprises the following steps:
s10: searching the Bluetooth signal of the mobile terminal. If the bluetooth signal of the mobile terminal is searched, the step S10 is performed; otherwise, the hearing aid mode is entered.
S20: and attempting Bluetooth connection with the searched mobile terminal. If the bluetooth connection is successful, go to step S30; if the Bluetooth connection fails, the hearing aid mode is entered.
S30: an attempt is made to acquire audio signaling for the bluetooth connection. If audio signal transmission of Bluetooth connection is acquired, entering a Bluetooth playing mode; and if the audio signal transmission of the Bluetooth connection is not acquired, entering a hearing aid mode.
Wherein, bluetooth playback mode does: and filtering the audio signal acquired to be connected with the Bluetooth, then performing compensation processing meeting hearing aid requirements, and playing the audio signal through a loudspeaker of a hearing aid Bluetooth headset. The hearing aid mode is as follows: acquire the audio signal of hearing aid bluetooth headset's microphone, carry out the compensation that satisfies the hearing aid demand and handle the back, through hearing aid bluetooth headset's loudspeaker broadcast.
After S10-S30, if the condition of the Bluetooth playing mode is met, the mobile terminal enters the Bluetooth playing mode, and carries out compensation processing after filtering the audio signal transmitted by the mobile terminal through Bluetooth, so that the hearing-impaired patient can clearly enjoy the Bluetooth playing function. If the condition of the hearing aid mode is met, the hearing aid mode is entered, and the audio signal output by the microphone is compensated, so that the hearing aid functions.
In order to further optimize the working state and user experience of the hearing aid bluetooth headset, the following improvements can be made.
For example, after entering the hearing aid mode, the working state of the Bluetooth functional module is continuously detected; if the working state of the bluetooth function module changes, returning to step S10; and if the working state of the Bluetooth functional module is not changed, maintaining the current working state. Through the monitoring to bluetooth function module, realize switching over hearing aid mode to bluetooth playback mode intelligently.
For example, after entering the bluetooth play mode, the audio signal transmission state of the bluetooth connection is continuously detected; if the audio signal transmission of the bluetooth connection is in the end state, returning to step S30; and if the audio signal transmission of the Bluetooth connection is in a continuous state, maintaining the current working state. Through the monitoring to bluetooth audio signal's transmission state, realize switching over bluetooth playback mode to hearing aid mode intelligently.
For example, because the distance between the speaker and the microphone is very close, when the hearing-aid bluetooth headset is worn, if the hearing-aid bluetooth headset is not worn in place, the howling sound of the hearing-aid bluetooth headset is large, discomfort is caused to a user, and the user experience is affected. In addition, after the user takes off the hearing-aid Bluetooth headset, the user often forgets to turn off the device, so that the device is in an uninterrupted state all the time, and howling is generated until the power is cut off, so that the user experience and the product intelligence convenience are reduced. Thus, the howling problem can be solved by adding in-ear detection. For example, the in-ear detection is required before entering the hearing-aid mode or the bluetooth playing mode, and the in-ear detection includes the steps of:
acquiring reflected infrared light received by a light sensing chip;
comparing the energy value of the reflected infrared ray with a preset threshold value; if the energy value of the reflected infrared light is smaller than a preset threshold value and the stabilization time of the energy value of the reflected infrared light is smaller than preset time, judging that the hearing aid module is not worn, closing the hearing aid function module, and stopping entering a Bluetooth playing mode and a hearing aid mode; otherwise, the user judges that the user wears the hearing aid function module, and the hearing aid function module is started to enter a corresponding Bluetooth playing mode or hearing aid mode.
For example, after the hearing aid bluetooth headset enters a normal use state, the hearing aid bluetooth headset may become loose or fall off, and the hearing aid bluetooth headset can be adjusted to a corresponding reasonable working state through wearing detection. For example, in this embodiment, after entering the hearing aid mode or the bluetooth play mode, it is necessary to perform wearing detection synchronously, and the wearing detection includes the steps of:
acquiring reflected infrared light received by a light sensing chip;
comparing the energy value of the reflected infrared ray with a preset threshold value; if the energy value of the reflected infrared light is smaller than a preset threshold value and the energy value stability time of the reflected infrared light is smaller than a preset time (for example, 3s), determining that the wearing state is not good; otherwise, the wearing state is judged to be good;
detecting the current working mode of the hearing-aid Bluetooth earphone, and if the hearing-aid Bluetooth earphone is in the hearing-aid mode and is in a worn state, continuing to execute playing; if the hearing-aid mode is the hearing-aid mode and the hearing-aid function module is not worn, the hearing-aid function module is closed; if the Bluetooth playing mode is adopted and the wearing state is adopted, the playing is continuously executed; if the Bluetooth playing mode is adopted and the Bluetooth playing mode is in the non-wearing state, the playing is paused, and the wearing state is detected again after the preset time; if the wearing state is detected again, the playing state before pause is resumed; if the wearing state is detected again, the hearing aid function module is closed.
As a further optimization, if the hearing-aid Bluetooth headset is detected to be in a state of not being worn again, the hearing-aid function module is closed, and whether the hearing-aid Bluetooth headset is put into the charging box or not is detected; if hearing aid bluetooth headset is not put into the box that charges, then maintain bluetooth function module operation, if hearing aid bluetooth headset has been put into the box that charges, then close bluetooth function module. Under the circumstances that the hearing aid bluetooth headset appears becoming flexible or drops, still for not wearing good state through the redetection, then judge whether it is put into the box that charges, adjust hearing aid bluetooth headset to corresponding reasonable operating condition.
For example, before step S10, machine pickup detection may also be included. The machine taking detection comprises the following steps: detecting whether the hearing-aid Bluetooth headset is taken out of the charging box or not; if the hearing aid Bluetooth headset is taken out of the charging box, executing the step S10; if the hearing-aid Bluetooth earphone is not taken out of the charging box, the hearing-aid function module and the Bluetooth function module are kept in a closed state. With the in-process that hearing aid bluetooth headset took out from the box that charges, judge whether it has been taken out, start corresponding functional module intelligently.
For example, in this embodiment, the step of detecting whether the hearing aid bluetooth headset has been taken out of the charging box is: detecting a voltage value of a charging port of the hearing-aid Bluetooth headset; if the voltage value of the charging port is smaller than the preset value, the charging port is judged to be taken out from the charging box; otherwise, the battery is judged not to be taken out of the charging box. For another example, in other embodiments, a trigger switch may be disposed on the hearing-aid bluetooth headset, and a trigger signal of the trigger switch is detected; if the trigger signal is an off-line signal, determining that the charging box is taken out; if the trigger signal is the parking signal, the charging box is judged not to be taken out.
In addition, in some embodiments, in the bluetooth play mode, a manual mode switching signal is detected, and if the manual mode switching signal is acquired, the hearing aid mode is switched to; in the hearing-aid mode, a manual switching mode signal is detected, and if the manual switching mode signal is acquired, the mode is switched to a Bluetooth playing mode. The manual switching mode signal can be realized by arranging a manual switching switch on the hearing-aid Bluetooth headset.
The control method of the hearing-aid Bluetooth headset is designed for hearing-impaired patients and has the Bluetooth playing function and the hearing-aid function. When the condition that satisfies bluetooth playback mode, establish audio signal transmission through bluetooth connection and mobile terminal, carry out filtering with audio signal and handle, then play through loudspeaker after the compensation processing that satisfies the hearing aid demand again to the realization is applicable to and listens to the bluetooth instant music who hinders the patient. When the condition of the Bluetooth play mode is not met, the hearing-aid mode is entered, the audio signal is acquired through the microphone, and then the audio signal is played through the loudspeaker after compensation processing meeting the hearing-aid requirement, so that the hearing-aid function is realized. Through above-mentioned design, have bluetooth instant music and hearing aid function concurrently for listen to hinder the patient and can hear sound clearly, promote the auditory sensation effect.
