In a detailed description of the invention of the present utility model, noise reduction microphone can use ANC (ActiveNoiseControl, active noise control system) mike, call mike 2 can use ANC mike, it would however also be possible to employ common Electret Condencer Microphone or electrodynamic type mike etc..Utilizing two noise reduction microphones in receiver, the voice signal received by mike carries out algorithm process, eliminates the noise signal being positioned on direction, human ear both sides, and before and after user 4 head, direction forms the wave beam of the figure of eight.
Specifically, Fig. 2-1 and Fig. 2-2 respectively illustrates the figure of eight wave beam according to this utility model embodiment and " heart " shape wave beam schematic construction.
Shown in as common in Fig. 1 to Fig. 2-1, in the earphone of this utility model specific embodiment, the receiver being positioned at user about 4 in ear is respectively arranged with a noise reduction microphone 1 and noise reduction microphone 1 ', it is fixed with call mike 2, call mike 2 and two noise reduction microphones on any one earphone cord 3 in two receivers and forms triangular structure.Wherein, F direction shown in accompanying drawing is expressed as the direction in user 4 head front, and B direction is expressed as with the direction at 4 rears of account.
4 call mike 2 is fixed for the convenience of the user, it is also possible on the shell or cavity of call mike 2, the easy fixed structures such as fixation clamp are set.In communication process, call mike 2 can be fixed on clothes by user 4 by fixed structure, and coordinates two noise reduction microphones being positioned at receiver to realize the up noise reduction process to earphone.
Specifically, Fig. 3 shows the earphone principle of noise reduction according to this utility model embodiment.
As shown in Figure 3, in the earphone noise reduction process of this utility model embodiment, utilize two noise reduction microphones (or ANC mike) in earphone, its voice signal received is carried out algorithm process, to eliminate the noise signal on direction, human ear both sides, and it is upwardly formed the wave beam of the figure of eight in user's head front and back, as shown in Fig. 2-1；Wherein, the cooperation of two noise reduction microphones, can improve the signal to noise ratio (unit dB) of earphone to a certain extent, promote speech quality.
Then, in communication process, the call mike on earphone cord equally receives voice signal, by the voice signal received by call mike is analyzed, the parameter such as the size of contrast phone signal, frequency, it is judged that the direction " F " of call voice signal and " B "；Finally, by algorithm process, the wave beam in " B " direction is eliminated by the wave beam of the figure of eight, only retain the wave beam on " F " direction, as shown in Fig. 2-2, ultimately form " heart " the shape wave beam being positioned at user's head front.
In another detailed description of the invention of the present utility model, shell includes that the protecgulum of adaptive connection and bonnet, phonation unit and corresponding noise reduction microphone are all housed in protecgulum and bonnet；Protecgulum is provided with master voice outlet tube, master voice outlet tube is provided with the pleasant ear muff of adaptive connection, pleasant ear muff can use the material such as silica gel or high resiliency polyester to be made, can be in close contact with auditory meatus after it inserts auditory meatus, enter middle ear and interior in ear with isolation sound, reach the purpose of sound insulation.In addition it is also possible to be pasted with the tuning sheet material of the acoustical behavior of regulation phonation unit on master voice outlet tube, to improve the acoustical behavior of earphone.Wherein, tuning sheet material can use screen cloth, sponge or non-woven fabrics etc..
Utilize above-mentioned according to earphone of the present utility model, it is fixed by call Mike is divided, guarantee noise reduction microphone and the position of shell wind of conversing is fixed, thus under the common effect of three mikes, form the voice signal of " heart " shape wave beam, and export to human ear as signal, it is possible to effectively reduce the outside noise impact on call, improve the speech quality of user.
Utilize above-mentioned earphone noise to external world to carry out noise reduction process and mainly include step as follows:
Step one: the noise reduction microphone voice signal to receiving carries out descending noise reduction process, eliminates the noise signal on direction, human ear both sides, and forms the wave beam of the figure of eight at head fore-and-aft direction.
In this step, two noise reduction microphones (or ANC mike) in earphone can carry out algorithm process to its voice signal received, and elimination is positioned at the noise signal on direction, human ear both sides, it is upwardly formed the wave beam of the figure of eight in user's head front and back, improves the noise when speech quality of earphone.
Step 2: the voice signal received is analyzed processing by the call mike being positioned on earphone cord, eliminates the wave beam being positioned at head rear, retains the wave beam being positioned at head front, finally realize the up noise reduction process to earphone.
Wherein, the call voice signal received by mike being pointed on earphone cord is analyzed, the various parameters such as the size of contrast phone signal, frequency, it is judged that the direction of call voice signal；Finally, by algorithm process, the wave beam that will be located in head rear on the wave beam of the figure of eight eliminates, only retain " heart " the shape beam signal being positioned at head front, and export to human ear, it is possible to realized the up noise reduction of earphone by call mike, improve speech quality.
Understanding, earphone of the present utility model includes up noise reduction unit and descending noise reduction unit, and up noise reduction unit includes two noise reduction microphones being positioned at receiver and the call mike being positioned on earphone cord；Descending noise reduction unit includes two noise reduction microphones being positioned at receiver.Under the common effect of three mikes (two noise reduction microphones and a call mike), it is possible to realizing the up noise reduction to earphone and descending noise reduction, noise reduction is obvious simultaneously.
Be can be seen that by above-mentioned embodiment, the earphone provided according to this utility model, by the noise reduction microphone in two receivers, the noise signal of user's ear both sides is eliminated, then under the cooperation of call mike, the noise signal that will be located in user's head rear is also carried out eliminating, the up noise reduction of earphone and descending noise reduction can be realized simultaneously, be effectively improved speech quality and the Consumer's Experience of user.
Describe in an illustrative manner according to earphone of the present utility model above with reference to figure accompanying drawing.It will be understood by those skilled in the art, however, that the earphone that above-mentioned this utility model is proposed, it is also possible on the basis of without departing from this utility model content, make various improvement.Therefore, protection domain of the present utility model should be determined by the content of appending claims.
