Abstract
The utility model discloses a voice-controlled headset, comprising a headset plug, a headset wire, a clamp, a switch, a microphone and a horn. The headset plug is connected with the headset wire, the right part of the headset wire is equipped with the clamp, and the right side of the clamp is equipped with the switch; the right side of the switch is equipped with the microphone, and the microphone is connected with the horn. The voice-controlled headset of the utility model is simple in structure and convenient in use, enables the portable electronic products, such as a mobile phone employing a 3.5 mm earphone interface, to possess the operation functions of controlling to play the previous music or the next music, making the music to be suspended, controlling the volume to be increased or decreased, etc., and enables a control function to be realized without needing complicated circuits.
Description
Technical field
The utility model relates to a kind of headset, relates in particular to a kind of acoustic control headset.
Background technology
Circular 3.5mm earphone interface increased popularity on the portable equipments such as present mobile phone, 3.5mm earphone interface interface only contains the earphone left and right acoustic channels, microphone signal; The earth signal interface, traditional line control earphone need extraly provide special control line and power interface, so on general 3.5mm earphone interface, can't realize controlled function; As play when listening to the music; Suspend a last head, next instruction such as grade.
Summary of the invention
The purpose of the utility model is to provide a kind of can control the headset product that electronics portable product such as mobile phone is operated to the deficiency of prior art.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of acoustic control headset comprises headset plug, headset line, clip, touch-switch, microphone, loudspeaker, and the headset plug links to each other with the headset line; The right part of headset line is provided with a clip; The right side of clip is a switch, and the right side of switch is a microphone, and microphone links to each other with loudspeaker.
Said headset plug is cylindrical four sections plugs.
Said loudspeaker are for comprising two loudspeaker of left and right acoustic channels.
Said switch is a touch-switch.
Circuit part: the left and right acoustic channels loudspeaker of earphone are connected on respectively between corresponding left and right sound track signals line pad of cylindrical socket and the ground pad; Microphone is connected between corresponding Mike's holding wire pad of cylindrical socket and the ground pad, and contact-making switch is connected in parallel on the two ends of microphone.
As when using headset to listen to the music, click the touch-switch on the headset, portable equipments such as mobile phone reduce through the dc offset voltage that analog-to-digital converter detects on the microphone, so portable equipments such as mobile phone begin receiving speech information from the microphone.Earlier voice messaging is recorded into the WAV formatted file, according to specific form voice PCM data are read then, speech data is carried out preliminary treatment.In pretreated process, earlier voice signal is carried out preemphasis, promote the HFS of sound, make frequency spectrum become smooth.Preemphasis makes voice messaging pass through digital filter H (z)=1-u/z, and the common value of u is between 0.9 to 1.After preemphasis is accomplished it is carried out normalization and divides frame to handle, do zero passage detection then.Frame length is got 30ms, and frame pipettes 1/3 frame length, and every frame comprises 240 voice points, and the judgement through zero-crossing rate and short-time energy obtains the frame that needs, multiply by window function then and obtains speech frame, and here our window function is got the Hamming window.Again every frame speech data is carried out feature extraction with LPCC (linear prediction cepstrum coefficient) algorithm.We do autocorrelation analysis earlier, obtain 12 rank LPC coefficients according to the Durbin algorithm then, thereby obtain 12 rank LPC characteristic vectors, transfer LPC cepstrum system parameters again to.Carry out identification maneuver after the completion, promptly with the storehouse in command template speech characteristic parameter file mate, find out immediate template, accomplish coupling, obtain command adapted thereto, we select the ADTW algorithm for use in this identifying.Portable equipments such as last mobile phone are carried out the command adapted thereto that matches, complete operation.
Method for using is: when the portable headsets that set the use standard such as mobile phone are listened to the music, click touch-switch, let system prepare to receive instruction.Aim at microphone and say instruction or knock microphone position with nail cover, and then click touch-switch, if then END instruction input not according to touch-switch, is crossed the automatic END instruction input of system in 3 to 4 seconds.System feeds back a prompt tone and representes to match instruction in earphone, and carries out command adapted thereto.
Last head when the utility model portable electronic products such as mobile phone simple in structure, easy to use, that make employing 3.5mm earphone interface possess like the control music; Next suspends, the function of operation such as volume plus-minus; Need not numerous and diverse circuit, can realize controlled function.

Embodiment
A kind of acoustic control headset comprises headset plug 1, headset line 2, clip 3, touch-switch 4, microphone 5, loudspeaker 6, and headset plug 1 links to each other with headset line 2; The right part of headset line 2 is provided with a clip 3; The right side of clip 3 is a switch 4, and the right side of switch 4 is a microphone 5, and microphone 5 links to each other with loudspeaker 6.
Said headset plug 1 is cylindrical four sections plugs.
Said loudspeaker 6 are for comprising two loudspeaker of left and right acoustic channels.
Said switch 4 is a touch-switch.
Circuit part: the left and right acoustic channels loudspeaker of earphone are connected on respectively between corresponding left and right sound track signals line pad of cylindrical socket and the ground pad; Microphone is connected between corresponding Mike's holding wire pad of cylindrical socket and the ground pad, and contact-making switch is connected in parallel on the two ends of microphone.
As when using headset to listen to the music, click the touch-switch on the headset, portable equipments such as mobile phone reduce through the dc offset voltage that analog-to-digital converter detects on the microphone, so portable equipments such as mobile phone begin receiving speech information from the microphone.Earlier voice messaging is recorded into the WAV formatted file, according to specific form voice PCM data are read then, speech data is carried out preliminary treatment.In pretreated process, earlier voice signal is carried out preemphasis, promote the HFS of sound, make frequency spectrum become smooth.Preemphasis makes voice messaging pass through digital filter H (z)=1-u/z, and the common value of u is between 0.9 to 1.After preemphasis is accomplished it is carried out normalization and divides frame to handle, do zero passage detection then.Frame length is got 30ms, and frame pipettes 1/3 frame length, and every frame comprises 240 voice points, and the judgement through zero-crossing rate and short-time energy obtains the frame that needs, multiply by window function then and obtains speech frame, and here our window function is got the Hamming window.Again every frame speech data is carried out feature extraction with LPCC (linear prediction cepstrum coefficient) algorithm.We do autocorrelation analysis earlier, obtain 12 rank LPC coefficients according to the Durbin algorithm then, thereby obtain 12 rank LPC characteristic vectors, transfer LPC cepstrum system parameters again to.Carry out identification maneuver after the completion, promptly with the storehouse in command template speech characteristic parameter file mate, find out immediate template, accomplish coupling, obtain command adapted thereto, we select the ADTW algorithm for use in this identifying.Portable equipments such as last mobile phone are carried out the command adapted thereto that matches, complete operation.
