When the control instruction of input is the first instruction, main control module 4 controls the first receiver module 1 to work, and the second receiver module 2 is treated
Machine, it is bone conduction communication mode by telephone system now, i.e. voice signal is sent by way of osteoacusis；
When the control instruction of user's input instructs for second, main control module 4 obtains the sound of ambient sound measurement module 5 again
Information, if main control module 4 judges that now environment is called as noisy environment, the control first of main control module 4 according to acoustic information
Device module 1 works, and the second receiver module 2 is standby, is still bone conduction communication mode by telephone system now；If main control module 4
Judge that now environment is without environment of making an uproar, then first receiver module 1 of the control of main control module 4 is standby, and second is called according to acoustic information
Device module 2 works, and is conductance communication mode by telephone system now, i.e. voice signal is sent by way of air transmitted.
It is identical with first embodiment, the present embodiment provide by telephone system, can flexibly select one kind according to the actual requirements
Communication mode, concrete principle is in first embodiment part it is stated that will not be repeated here.
Compared to first embodiment, the present embodiment provide by telephone system, be also provided with ambient sound measurement module 5, with
Family inputs control instruction according to user instruction input module 3, to start the second receiver module 2, that is, takes conductance communication party
During formula, main control module 4 will not be immediately performed corresponding actions, but can obtain the information of ambient sound measurement module 5, only without ring of making an uproar
Conductance communication mode can be just taken under border, because under noisy environment, conductance communication mode can not realize effective call, this
When, it is insignificant that user, which selects conductance communication,.
In summary, the present embodiment provide by telephone system, can combining environmental state come with user's control instruction it is final
Communication mode is controlled, can avoid some invalid controls of user, practicality is higher.
3rd embodiment
Fig. 3 is the structural representation by telephone system that the 3rd embodiment of the application provides.
Such as Fig. 3, what the present embodiment provided is included the first receiver module 1, the second receiver module 2, master control by telephone system
Module 4, user instruction input module 3 and range finder module 6；
The first receiver module 1 is used to send voice signal by way of osteoacusis；Second receiver
Module 2 is used to send voice signal by way of air transmitted；The user instruction input module 3 is used to input for user
Control instruction；
The range finder module 6 is used to measure by telephone system and the distance of user；Specifically, range finder module 6 can be red
Outer rangefinder, when infrared range-measurement system measurement is not less than pre-determined distance threshold value by the distance between telephone system and user, it is judged as
At a distance, otherwise for closely.
The signal input part of the main control module 4 is connected with user instruction input module 3 and range finder module 6 respectively, described
The signal output part of main control module 4 is connected with the first receiver module 1 and the second receiver module 2 respectively, to be used according to input
The range information that the control instruction and range finder module 6 of family instruction input module 3 measure controls the first receiver module 1 and
The working condition of two receiver modules 2.
The present embodiment provide be by telephone system, its operation principle：
User inputs control instruction by user's instruction input module 3, and main control module 4 obtains the control instruction, works as user
When the control instruction of input is the first instruction, main control module 4 obtains the range information that range finder module 6 measures again, if it is determined that this
When for closely, then main control module 4 controls the first receiver module 1 to work, and the second receiver module 2 is standby, is adopted by telephone system
With bone conduction communication mode, i.e. voice signal is sent by way of osteoacusis；If it is determined that it is now remote, then main control module
4 the first receiver modules 1 of control are standby, and the second receiver module 2 is worked, and conductance communication mode, i.e. sound are used by telephone system
Signal is sent by way of air transmitted.
When the control instruction of user's input instructs for second, main control module 4 need not obtain the distance that range finder module 6 measures
Information, directly the first receiver module 1 of control is standby, and the second receiver module 2 works, and is that conductance communicates by telephone system now
Mode, i.e. voice signal are sent by way of air transmitted.
It is identical with first embodiment, the present embodiment provide by telephone system, can flexibly select one kind according to the actual requirements
Communication mode, concrete principle is in first embodiment part it is stated that will not be repeated here.
Compared to first embodiment, the present embodiment provide by telephone system, be also provided with range finder module 6, user according to
User instruction input module 3 inputs control instruction, to start the first receiver module 1, that is, main when taking bone conduction communication mode
Control module 4 will not be immediately performed corresponding actions, but, the information of range finder module 6 can be obtained, only can just be taken in closely state
Bone conduction communication mode, because if by telephone system apart from user too far, bone conduction communication mode can not realize effective call, this
When, it is insignificant that user, which selects bone conduction communication,.
In summary, the present embodiment provide by telephone system, can combine range information and user's control instruction come it is final
Communication mode is controlled, can avoid some invalid controls of user, practicality is higher.
In addition, the technology of second embodiment and 3rd embodiment can be also combined together, more intelligent selection communication
Mode, further to improve the practicality by telephone system.
