Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, a kind of comfortableness noise cancelling headphone that the utility model embodiment provides, comprises a housing 100, and in this specific embodiment, housing 100 is ep-type material preferably.Circuit control module 110, one loud speaker 120 and a microphone apparatus 130 is comprised in housing 100.Circuit control module 110 comprises filter circuit 111, negater circuit 112 and a circuit amplifier 113, filter circuit 111, negater circuit 112 and circuit amplifier 133 are electrically connected successively, wherein, filter circuit 111 is electrically connected with microphone apparatus 130, and circuit amplifier 113 is electrically connected with loud speaker 120.During concrete operations, microphone apparatus 130 receives voice signal, and pass signal back filter circuit 111, after the process of various filtering, such as NOTCH, HIGH PASS etc., be delivered to negater circuit 112 settling signal reverse, then after being passed to circuit amplifier 113 amplification, export loud speaker 120 to.But produce because the hot-tempered signal that disappears amplifies according to ambient signal inverse filtering, after the music signal that can export with loud speaker 120 itself carries out superposing and mixes, the hot-tempered signal that disappears can offset the environmental noise in the external world arround loud speaker 120, and then the music of high-quality is provided, to music well love person bring different auditory effect.
Referring again to Fig. 2, particularly, described loud speaker 120 comprises the vibrating diaphragm 122 that a body 121 and is located at body 121 upper surface.Body 121 is one have upper end open and the box body structure made by aluminum material.Because aluminium has good ductility, lighter weight, has good conduction and heat conductivility, and therefore preferred aluminium is as the material of body 121.Vibrating diaphragm 122 comprises the ring-type vibration section 1222 that a center through hole 1221 and is positioned at center through hole 1221 outer peripheral areas.Vibrating diaphragm 122 goes out sound by vibration section 1222 towards sender, it is the annular sound wave outwards dispersed that vibration section 1222 goes out territory, the range of sound, when vibration section 1222 vibrates, front sound wave and back side sound wave can be produced, and vibrating diaphragm 122 vibration itself can produce low frequency or part high frequency.Vibrating diaphragm 122 upper surface is also provided with a catch net 123, and catch net 123 is an annular cover structure, and catch net 123 is provided with some concave points 1231, and catch net 123 and center through hole 1221 are coaxially arranged.In addition, microphone apparatus 130 device is arranged in center through hole 1221 simultaneously, and coaxially arranges with center through hole 1221, effectively improves the motor reaction of vibrating diaphragm 122 and have adjusted the intensity of bass, meet required range and tonequality fineness, improve the hearing enjoying of people.
Referring again to Fig. 3, further, described housing 100 one end is installed with an earplug 200, due to low frequency signal transmit time, have strong vibration, air is also vibrated thereupon, and the eardrum in the ear of people can be subject to the strong shock of air molecule, and Long-Time Service earphone causes infringement to a certain degree can to the hearing of people.Earplug 200 of the present utility model comprises leads cylinder record 210 and and is connected to the noise reduction ring 220 of leading cylinder record 210 upper end, by leading the setting of cylinder record 210, sound is guided, and the sound that sends of earphone is by the outside of leading cylinder record 210 and reach noise reduction ring 220, such people just can clearly hear required sound in a noisy environment.In addition, lead middle part in cylinder record 210 and be installed with an acoustic energy adjustable pipe 211, in acoustic energy adjustable pipe 211, be provided with sound absorbing layer 2111.When sound directive eardrum back reflection is returned, this enables sound be absorbed timely and discharge, and can solve the problem that eardrum bears sonic stimulation to a certain extent.
Referring again to Fig. 4, further, described earplug 200 outer peripheral edges are arranged with a spring-backed quill 300, form an airflow layer 400 between spring-backed quill 300 and earplug 200.Spring-backed quill 300 is made up of silica gel material, arbitrarily can stretch contraction, can change the size of earphone, reaches the function of applicable human antrum auris size.Spring-backed quill 300 offers some pore (not shown), pore is used for providing gas in airflow layer 400.During concrete use, people first can gently extrude spring-backed quill 300 with have gentle hands, discharge the gas in airflow layer 400, make airflow layer 400 be in negative pressure state by pore.Then earphone is filled in duct, arrive the position be applicable to, then unclamp hand, air enters airflow layer 400 from pore, and spring-backed quill 300 outwards expands, until withstand duct, makes the size of earphone just meet the size of human antrum auris.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
