Word signal is decoded, and obtains decoded audio electrical signal, i.e. acquisition analog signal.
First audio electrical signal is converted to the first voice signal by receiver 12；Driver 13 turns the second audio electrical signal
It is changed to the second voice signal.Wherein, the first audio electrical signal and the second audio electrical signal are given birth to by decoded audio electrical signal
At two-way audio electric signal.
Optionally, the decoded audio electrical signal is also divided into two-way audio electric signal by the decoder 11, and
The frequency response and gain of the road two-way audio electric signal Zhong Mei audio electrical signal are handled, first audio-frequency electric is obtained
Signal and second audio electrical signal, first audio electrical signal have the first frequency response and the first gain, second sound
Frequency electric signal has the second frequency response and the second gain.
It should be noted that since receiver 12 is different from the frequency characteristic that driver 13 is expressed, therefore be not available identical
Audio frequency parameter.Need to be arranged 2 groups of processing accesses, independent processing enters the audio electrical signal of receiver 12 all the way, and another way is special
Door processing enters the audio electrical signal of driver 13.
For example, decoded audio electrical signal is also divided into two-way audio electric signal by decoder 11, this two-way audio electricity
Signal can be the same audio electrical signal.For example, the frequency response and gain of this two-way audio electric signal can be it is identical.
Then, decoder 11 can frequency response to the road two-way audio electric signal Zhong Mei audio electrical signal and gain handle, obtain
First audio electrical signal and the second audio electrical signal.Wherein, the first audio electrical signal have the first frequency response and the first gain, second
Audio electrical signal has the second frequency response and the second gain.Next, the first audio electrical signal can be inputted receiver 12, by the
Two audio electrical signal input actuator 13.
Optionally, the driver 13 is linear motor；
The linear motor generates vibration according to second audio electrical signal, and second audio electrical signal is converted
For second voice signal.
Above-mentioned driver 13 can be linear motor 131.Linear motor 131 generates vibration according to the second audio electrical signal,
The second audio electrical signal is converted to the second voice signal.The coil of linear motor 131 is fixed on the shell of linear motor 131
On, then internal movement of pendulum generates vibration.When the vibration frequency of linear motor 131 is in human auditory system frequency range, and
The oscillation intensity of linear motor 131 is larger, so that it may by ear recognition at voice signal.
It optionally, further include driver；The driver is connect with the decoder 11, and the driver and the line
Property motor connection；
The driver amplifies processing to second audio electrical signal；
The second audio electrical signal Jing Guo enhanced processing is converted to second voice signal by the linear motor.
Audio electrical signal transition components 1 can also include driver 14.Driver 14 is connect with decoder 11, and driver
14 connect with linear motor 131.As shown in Fig. 2, for the schematic diagram of another audio electrical signal transition components.14 pairs of driver tools
