It can focus on to be filtered information source noise in this case；When slave is in interior, slave can be set to indoor mould
Formula, indoors under environment, interchannel noise is serious relative to interference of the information source noise to signal, and therefore, slave is in this case
It can focus on to be filtered interchannel noise；In a sleep mode, then information source noise and interchannel noise can be carried out simultaneously strong
Change filtration treatment, it might even be possible to actively reduce the intensity of sound of non-noise voice signal, provide one for user and quietly sleep
Dormancy environment.
As shown in figure 4, in the present embodiment, the slave 200 in embodiment three further includes the second human-computer interaction module 205,
Second human-computer interaction module 205 is connect with 2031 wire communication of the second control unit.
In the present embodiment, the second human-computer interaction module 205 is used to refer in the listening mode setting for getting user's input
Mode setting instruction will be listened to when enabling is sent to the second control unit 2031；
Second control unit 2031 is used to that current listening mode to be arranged according to listening mode setting instruction, and triggers second
Noise reduction unit 2032 is according to noise reduction process mode corresponding with current listening mode, to the second of signal source highest priority
Voice signal carries out noise reduction process；Second control unit 2031 is also used to when not receiving listening mode setting instruction, default
Using the listening mode being arranged.
In a particular application, the second human-machine exchange module may include the touch controlled key for being set to host, mechanical key, open
The human-computer interactions device such as pass, touch screen.User can by the second human-computer interaction module or pass through voice control or gesture control
Mode processed inputs listening mode setting instruction, to switch and be arranged the operating mode of the host.If carrying out voice signal
User does not switch the operating mode of the host before processing, then listening mode of the default according to being arranged before is handled,
If the host is that second of booting uses at this time, the listening mode being arranged is the listening mode of default setting.Together
Reason can also pass through corresponding human-computer interaction device, voice control or gesture control mode to the open and close machine control of the host
To realize.
In one embodiment, the second human-computer interaction module include the key being connect with the second control unit wire communication and
Display screen.
In one embodiment, the second human-computer interaction module may include slave power switch key, slave power supply indicator,
Slave listen to mode selecting key, volume "+" key, volume "-" key, slave working station indicator (including charging indicator light, wait fill
Electric indicator light, multiple status indicator lamps etc.), slave Bluetooth pairing key (key be in aperture, need using contact pin trigger open
The hiding key for opening or closing can prevent from accidentally touching and arbitrarily changing Bluetooth pairing setting).
In a particular application, when slave charges, if charging indicator light is always on, indicator light to be charged extinguishes, then it represents that from
The electricity of machine is filled.Safe to guarantee to use, slave is automatically set to off-mode in charging.
In a particular application, the matching method of host and slave are as follows: host and slave have been preset as being located at other side when dispatching from the factory
Communication network within the scope of i.e. automatic matching, after opening host and slave, the working station indicator of a certain color of host and slave processors
Jump to another color.If it was found that host and the connection failure of slave automatic matching, can be matched again by following operation:
Host and slave processors are opened, are first referred to using the working condition of a certain color of contact pin pressing host Bluetooth pairing key to host
Show that lamp extinguishes, host is made the state to be paired such as to enter, reuses a certain face that contact pin presses slave Bluetooth pairing key to host and slave processors
The working station indicator of color jumps into another color simultaneously, while the earphone by connecting with host hears " bluetooth has connected "
Prompt tone indicates host and slave processors successful matching.
The mode of slave connection audio frequency apparatus are as follows: after host and slave processors are opened, slave and audio frequency apparatus are connected by tone frequency channel wire,
It can be used after hearing the sound that audio frequency apparatus issues by the earphone connecting with host.
The shutdown mode of slave are as follows: pressing slave switch key, until whole indicator lights extinguishes, completion is shut down.
Embodiment five
As shown in figure 5, the present embodiment provides a kind of hearing assistant systems 1000 comprising in embodiment one or embodiment two
Host 100 and embodiment three or example IV in slave 200.
In a particular application, the host of hearing assistant system and slave can match, extraneous by slave acquisition
Voice signal obtains the audio signal of audio frequency apparatus transmission and radios to host after being handled, the host acquisition external world
Voice signal obtains the audio signal that wireless telecom equipment is sent or the audio signal that slave is sent, and passes through after being handled
Earphone is exported to the ear of user.
In a particular application, host can specifically be designed to the Mobile terminals such as hearing aid, bluetooth headset,
The host and slave of hearing assistant system provided in this embodiment can be applied to following scene:
1, when host is used alone, ambient sound can easily be listened by opening host, and pressing volume "+" key, volume "-" key is adjustable
Save volume.It presses host and listens to mode selecting key, hear " ticking " sound prompt tone, host can be set to " indoor mould
Formula ", can clear listening environments sound；Pressing host listens to mode selecting key again, hears " tick, tick " two sound prompt tone, can
See that host is set as " outdoor mode ", the interference of decreasing environmental noise function.
2, when wireless telecom equipment is mobile phone, host can receive calls.After host and Bluetooth of mobile phone successful matching
The phone audio data that mobile phone is sent is received, In Call size is adjusted in pressing volume "+" key, volume "-" key.
3, when wireless telecom equipment is other bluetooth equipments, host can listen to the sound of other bluetooth equipments.For example, its
When his bluetooth equipment is radio or Baffle Box of Bluetooth, after host and the success of other electronic equipment Bluetooth pairings can broadcast listening or
Music.
4, host and slave pairing use and audio frequency apparatus be television set when, slave connect television set audio output interface
After can easily watch TV program, pressing volume "+" key, volume "-" key be adjusted In Call size.
5, when being linked up with other people, slave is worn on other people (or hand-held), can clearly listen to other people voices,
It is exchanged with realizing with light between other people.When other people are teachers, slave is worn over teacher or is placed on dais, it can
Teacher's teaching is not heard.
6, the mode conversion regime of slave.It presses slave and listens to mode selecting key, hear " ticking " sound prompt tone, it can will be from
Machine is set as " indoor mode ", can clear listening environments sound；Pressing slave listens to mode selecting key again, hear " tick,
