Description
Technical field
The present invention relates to a kind of audio system, especially a kind of voice input device, audio output device and method for transmitting signals thereof.
Background technology
Wireless microphone system comprises microphone and loudspeaker in the prior art.Microphone comprises the signal delivery module, and loudspeaker comprise signal receiving module.Pass through the radio-frequency technique transmit audio signals (or claiming sound signal) of 2.4GHz between signal delivery module and signal receiving module, and the audio signal that microphone is received reaches sound horn.
The shortcoming of this system be the user first use wireless microphone system before, the user need be about to microphone earlier and carry out frequency with loudspeaker.Let signal delivery module and signal receiving module use same channel transmit audio signals.The user operates this need carry out the following step to the sound interval preface:
Step 1: start loudspeaker; Loudspeaker are returned to mode of operation from standby mode.
Step 2: start microphone; Microphone is started shooting.
Step 3: press loudspeaker to the frequency button; Through pressing, loudspeaker are got into the frequency pattern to the frequency button.
Step 4: press microphone to the frequency button; Through pressing, microphone is got into the frequency pattern to the frequency button.
Though this is comparatively complicated as far as sound interval ordered pair user, under comparatively simple use situation, general user still still can accept.Because if being paired between microphone and loudspeaker is fixing,, the corresponding one or more microphones of loudspeaker are only arranged as under home environment.Then only need carry out once the sound interval preface, and can supply day continued to use, the user does not need repetitive operation to the sound interval preface.
Yet if use situation possibly to use by corresponding different loudspeaker as microphone, the microphone that for example same teacher uses needs on different classrooms, to correspond to the loudspeaker in different classrooms.Then this a microphone and one of which loudspeaker to frequency after, like desire audio signal is reached another sound horn, then need carry out once more the sound interval preface, make microphone and another loudspeaker carry out can using microphone to behind the frequency.If these two loudspeaker for this teacher special use, then after to frequency, need not to carry out once more to frequency.
But when more complicated as if the use situation, a plurality of microphones that for example a plurality of teachers use need on different classrooms, correspond to the loudspeaker in a plurality of classrooms.Then the teacher is before giving lessons at every turn, all needs oneself the loudspeaker in microphone and classroom are carried out once can using microphone to after the sound interval preface.So, quite inconvenience in the use.
Therefore, between existing microphone and loudspeaker to the sound interval preface, still have it to improve the space.

Embodiment
Referring to Fig. 1, the system of the embodiment of the invention comprises voice input device 100 and audio output device 200, and 200 of voice input device 100 and audio output devices can carry out the wireless audio signal transmission.For example, voice input device 100 can be microphone apparatus, is used for receiving outside sound, and conversion sound is wireless audio signal.For example, audio output device 200 can be loudspeaker device, is used for receiving the wireless audio signal that voice input device 100 transmits, and converts voice output into.
In an embodiment, voice input device startup module 130, signal delivery module 150, voice input device are coupled respectively to voice input device control module 110 to frequency module 170 and trigger module 190.
Trigger module 190 can be used to produce first signal 191.Voice input device starts module 130 and can be used to according to first signal 191, starts voice input device 100.That is to say that after voice input device control module 110 detected first signal 191 of trigger module 190 outputs, the order voice input device started module 130 and starts voice input device 100, and makes voice input device 100 starts.For example, trigger module 190 can be diverter switch, supplies user's operation.In addition, trigger module 190 can be button, joystick or other device, contact panel also capable of using.
Referring to Fig. 1, Fig. 2, signal delivery module 150 is used for according to first signal 191, transmits secondary signal 301 to audio output device 200, starts audio output device 200.Detect first signal 191 of trigger module 190 outputs when voice input device control module 110 after, voice input device control module 110 command signal delivery modules 150 transmit secondary signal 301, and make audio output device 200 starts.On the other hand, when voice input device 100 was accomplished frequency with audio output device 200, signal delivery module 150 transmitted wireless audio signal 301 to audio output device 200, and receives wireless audio signal 301 by audio output device 200.
Referring to Fig. 2, signal delivery module 150 comprises first delivery unit 151 and second delivery unit 152; Signal receiving module 250 comprises first receiving element 251 and second receiving element 252.First delivery unit 151 is used for wireless transmission secondary signal 301.First receiving element 251 is used for receiving secondary signal 301.Second delivery unit 152 is used for utilizing the wireless transmission wireless audio signal 301 of selected channel to back decision frequently.Second receiving element 252 is used for utilizing the selected channel to back decision frequently to receive wireless audio signal 301.
First delivery unit 151 and first receiving element 251 can pass through infrared ray, and (Infra Red, IR) (Frequency Modulation, FM) carrier wave or other carrier wave that need not to carry out in advance frequency carry out communication for carrier wave or frequency modulation.Second delivery unit 152 and second receiving element 252 can carry out communication through radio frequency (Radio frequency) technology.Radio frequency can use 1.9GHz, 2.4GHz, 5.8GHz or other frequency range to carry out communication, but the present invention is not as limit.
In addition, according to different embodiments of the invention, first delivery unit 151 and second delivery unit, 152 alternatives are merged into a delivery unit.First receiving element 251 and second receiving element, 252 alternatives are merged into a delivery unit.And it transmits the signal alternative and comprises the signal that other prior art provides, in order to overall operation.
For instance, the 2.4GHz frequency range uses the channel in the 2.4GHz to 2.5GHz to carry out communication.To frequency the time, voice input device 100 gets into voice input device to the frequency pattern, and audio output device 200 also gets into audio output device to the frequency pattern.One of them scans channel second delivery unit 152 and second receiving element 252, and then determines suitable selected channel.In various embodiment, alternative of the present invention utilizes voice input device 100 or audio output device 200 as initiatively frequency being held.Wherein, selected channel is a kind of in a plurality of channels in the 2.4GHz to 2.5GHz.Then, notify second delivery unit 152 or second receiving element 252 to be adjusted to same selected channel through first delivery unit 151 and first receiving element 251.In view of the above, second delivery unit 152 or second receiving element 252 can transmit or receive wireless audio signal 301.
