Abstract
A real-time voice recording and playing earphone is characterized in that low audio-frequency signals are picked up by a microphone, transmitted to an integrated audio processing module and processed by an amplifier circuit and a noise reducing circuit, and then audio frequency with normal volume can be played by an earphone type loudspeaker. Delay time from audio-frequency pickup to sound playing is equal to or smaller than 300ms, and the sound playing effect is improved along with reduction of the delay time, thereby realizing real-time recording and playing effect. By aid of the real-time voice recording and playing earphone, a user can hear voice with the normal volume even though the user reads or talks in a low voice. The real-time voice recording and playing earphone is mainly applied to offices or other occasions inconvenient for people to speak English loudly.
Description
Technical field
The utility model relates to a kind of off beat frequency signal that picks up behind amplification, noise reduction, the instant (device of earphone-type loudspeaker plays of delaying time≤300ms) pass through.
Background technology
The people of present many English learnings adopts loudly and reads, says that English gives the mode of oneself listening, and reaches the ability of oneself hearing of taking exercise.But the occasion that much is not easy to bother others (for example in office, subway carriage, in the public transport compartment etc.), can not declaim, not have the effect of tempering hearing.
At present, known Headphone device with miniature pickup microphone (hereinafter to be referred as the A device) is after picking up audio signal by microphone, is transferred to receiving and processing device (for example computer), after treatment, stores.If desire is listened this audio frequency, to play by processing unit again, audio signal is through loudspeaker plays.This Headphone device characteristics are not audio signal itself, do not exist between sound pick up equipment and the playback set and get in touch, and record that can't be instant, playback be signal frequently.
Present known a kind of device that is phonetical repeater that also has, it is being pre-stored in tape or from the mini microphone picked up audio signals, depositing volatile memory in, by operation, playing back that audio frequency repeats, i.e. record function.It is not that promptly to put be purpose with i.e. record, is with can the re-reading time long as one of performance index excellence.
The present known a kind of device (hereinafter to be referred as the B device) that also has, miniature pickup microphone picked up audio signals is after amplifying, by powerful audio amplifier or loudspeaker playback, though this kind device is can recording playback audio signal immediately, but because it is applied in and makes more people hear speaker's occasion, thus be used for that the rating of set of playback is big, volume is big, do not make collect pick up, the headphone structure of playback one, can not be applied to only put to oneself and listen the occasion that is not easy to bother others.
Summary of the invention
In order to adapt to new application requirements, overcoming that the A device can not promptly record is the playback deficiency of signal frequently, does not also make the problem of miniature headphone structure in order to solve the B device.The utility model provides a kind of voice promptly to record and promptly puts earphone.This device can not only recording playback audio signal immediately, and can make earphone forms easy to carry and use.
The technical scheme that its technical problem that solves the utility model adopts is: after mini microphone picks up audio signal, be transferred to audio processing modules, handle by amplifying circuit, Dolby circuit, come out by the earphone-type loudspeaker plays then.Audio processing modules just is integrated on this earphone.From picking up audio frequency to playing out sound, time-delay≤300ms, and the smaller the better, to realize that promptly effect is promptly put in record.
The beneficial effects of the utility model are, only need little sound read or say that the ear of oneself can be heard the sound of normal quantity by this device.It is mainly used in being not easy to bother others' occasion (for example in office, subway carriage, in the public transport compartment etc.), is employed to the personage who reads by oneself to oneself sounding taking exercise English Listening Comprehension.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the logic diagram of processing module inside.
Among the figure: 1. mini microphone, 2. support bar, 3. audio processing modules, 4. left ear (or auris dextra) loud speaker, 5. auris dextra (or left ear) loud speaker.
Embodiment
In Fig. 1, mini microphone (1) picks up audio signal, by the built-in lead of support bar (2), sends audio processing modules (3) to, plays back through passing through left and right sides ear loud speaker (4,5) behind amplification, the noise reduction in audio processing modules.
In Fig. 2, mainly disclosed the internal work logic of audio processing modules (3): after audio processing modules (3) receives the audio signal of mini microphone (1) collection, amplify through amplifying circuit, again through the Dolby circuit noise reduction, the inner processing procedure of audio processing modules (3) needs the electric power of battery, for the implement device mobility, processing module built-in one the joint No. 7 batteries.When not working, processing module, cuts off electric power by operating switch for power saving.Indicate whether in running orderly by a light-emitting diode, simultaneously the volume by-pass cock can be regulated the size of audio signal.Last audio processing modules (3) is given left and right sides ear loud speaker (4,5) audio signal of handling and is played back.Whole process time-delay≤300ms.
Claims (1)
1. voice are promptly recorded and are promptly put earphone, have pickup mini microphone and miniature headset speakers, volume is little, removable, it is characterized in that: mini microphone (1) picks up audio signal, by the built-in lead of support bar (2), be transferred to audio processing modules (3), in audio processing modules, pass through left and right sides ear loud speaker (4 behind process amplification, the noise reduction, 5) play back, audio processing modules (3) comprises: amplifying circuit, Dolby circuit, relay indicating light (light-emitting diode), operating switch and volume adjustment knob, No. 7 dry cell 1 joints.
