Embodiment
Below, be described in detail with reference to accompanying drawing with regard to embodiments of the invention:
Fig. 2 is that Fig. 3 is the schematic diagram based on wireless headset of the present invention based on the embodiment schematic diagram that utilizes the voice controller of wireless headset of the present invention.
As shown in the figure, the present invention is made of wireless headset 10 and voice controller body 20.
It sends above-mentioned wireless headset 10 perception to body with wireless signal after wearing earphone, and receive the laggard line output of corresponding voice output signal, tut controller body 20 receives perception when wearing the signal of earphone when above-mentioned wireless headset 10, according to the menu of prior setting only to above-mentioned wireless headset 10 output sound output signals or simultaneously to above-mentioned wireless headset 10 and loud speaker 26 output sound output signals.
For this reason, above-mentioned wireless headset 10 comprise sending part 11, wear earphone sense part 12, power suppling part 13, control part 14, power save circuit portion 15, earphone efferent 16 and sound receiving part 17.
Wear earphone sense part 12 perception users and wear earphone, sending part 11 sends with wireless signal the above-mentioned earphone perception state of wearing of wearing 12 perception of earphone sense part to above-mentioned body.Above-mentioned earphone sense part 12 suitable heat sensor or the piezoelectric transducers etc. of utilizing of wearing.
Sound receiving part 17 receives the voice output signal from above-mentioned body, output meets the voice signal of the volume and the tone color of output condition behind the voice output signal that the above-mentioned sound receiving part 17 of control part 14 analyses is received, the voice output signal that the above-mentioned control part 14 of earphone efferent 16 outputs sets.
Power suppling part 13 is to each several part supply driving power, and power save circuit portion 15 carries out electricity-saving function when not using.Above-mentioned power suppling part 13 suits to be made of interchangeable battery.
In addition, tut controller body 20 comprises sound transmitting 21, perceptual signal acceptance division 22, control part 23, sound input part 24, voice decoder 25 and loud speaker 26.
Sound transmitting 21 sends the voice output signal to above-mentioned wireless headset 10, and perceptual signal acceptance division 22 receives from above-mentioned wireless headset 10 and wears the earphone perceptual signal.
Control part 23 is when said sensed signal receiving part 22 receives perception when wearing the signal of earphone, according to the menu of prior setting only to above-mentioned wireless headset 10 output sound output signals or simultaneously to above-mentioned wireless headset 10 and loud speaker 26 output sound output signals.At this moment, the volume that will adjust in advance according to the output condition of above-mentioned wireless headset 10 of above-mentioned control part 23 and tone color are included in the tut output signal and export.
Sound input part 24 will be outputed to the voice signal of loud speaker 26 or earphone 10 by the stereo set input.Voice decoder 25 will convert exportable signal to by the voice signal of above-mentioned input part 24 inputs.
In addition, above-mentioned wireless signal and tut output signal comprise any aspect in infrared signal or the RF signal at least.
In addition, tut controller 20 comprises a series of all appts that can play sound such as common television set, sound equipment, cassette recorder, video tape recorder and DVD as instrument that can output sound.
Fig. 4 is the sequential flowchart of control procedure of the present invention, and the effect of the present invention that just has said structure is described in detail as follows:
The voice controller 20 of the invention described above comprises a series of all appts that can play sound such as common television set, sound equipment, cassette recorder, video tape recorder and DVD as instrument that can output sound.
At first, when the user wore earphone 10, it wore earphone the automatic perception of wireless headset 10 meetings, and this is sent to body 20 with wireless signal.
That is, when wearing earphone sense part 12 perception users when wearing earphone, sending part 11 sends to above-mentioned body 20, i.e. television set or external audio equipment with the above-mentioned perception state of wearing earphone of wearing 12 perception of earphone sense part with wireless signal.
At this moment, the above-mentioned earphone sense part 12 of wearing utilizes rapid perception user correctly such as heat sensor or piezoelectric transducer to wear the state of earphone.
On the other hand, do not perceive it when wearing earphone when wearing earphone sense part 12, power save circuit portion 15 can carry out electricity-saving functions, prevents that power suppling part 13 from consuming unnecessary battery.
Afterwards, voice controller body 20 receives perception when wearing the signal of earphone when above-mentioned wireless headset 10, according to the menu of prior setting only to above-mentioned wireless headset 10 output sound output signals or simultaneously to above-mentioned wireless headset 10 and loud speaker 26 output sound output signals.
That is, perceptual signal acceptance division 22 receives from above-mentioned wireless headset 10 and wears the earphone perceptual signal.
Control part 23 receives perception when wearing the signal of earphone when said sensed signal receiving part 22, according to the menu of prior setting only to above-mentioned wireless headset 10 output sound output signals or simultaneously to above-mentioned wireless headset 10 and loud speaker 26 output sound output signals.
At this moment, the volume that will adjust in advance according to the output condition of above-mentioned wireless headset 10 of above-mentioned control part 23 and tone color are included in the tut output signal and export.
Therefore, wear earphone owing to perceive, sound transmitting 21 sends to above-mentioned wireless headset 10 with the voice output signal.
Afterwards, the sound receiving part 17 of wireless headset 10 receives the voice output signal from above-mentioned body 20, output meets the voice signal of the volume and the tone color of output condition behind the voice output signal that the above-mentioned sound receiving part 17 of control part 14 analyses is received, the voice output signal that the above-mentioned control part 14 of earphone efferent 16 outputs sets.
Therefore, the user only just can listen to sound by earphone easily automatically by the action of wearing earphone.
In addition, when the user finishes to use earphone 10, wear earphone sense part 12 with its perception after, according to the menu of prior setting,, or stop the action of stereo set by loud speaker 26 output sounds.
At this moment, during by loud speaker 26 output sounds, sound input part 24 will output to the voice signal of loud speaker 26 by stereo set input, and voice decoder 25 will convert exportable signal to by the voice signal of tut input part 24 inputs.
At this moment, above-mentioned wireless signal and tut output signal comprise any aspect in infrared signal or the RF signal at least.
The voice controller of the invention described above is applicable to sound equipment, cassette recorder, television set, video tape recorder (VCR), watch-dog, television reception special-purpose computer and set-top box (STB), and is equally applicable to simulated television, digital television and satellite TV set.
More than, the embodiment that suits for the present invention has carried out diagram and explanation, but the present invention is not limited to the foregoing description, in the field under the present invention of the main points of the present invention that in not exceeding the claim scope, require, no matter who can carry out various changes to it if having common knowledge people, and this change meeting is in the claimed range of being put down in writing.
