Abstract

The utility model relates to an earphone of reducing interference; primarily, a microphone is arranged at the axis of the front part of a loudspeaker; a microphone is also arranged on the outer casing of the earphone; thus, one microphone of the microphones is arranged in a quiet antrum auris which is not interfered by outside to accept parts of sound waves generated in the antrum auris. Simultaneously, the other microphone is arranged on the outer casing of the microphone to accept sounds from a mouth of a speaker; the assembled microphones are in mutually auxiliary sound acceptance states to respectively pick up sound sources of low sound volumes to collect sound sources of high sound volumes; the sound acceptance degree of the microphone arranged on the outer casing of the microphone is arranged in low ranges as the pickup compensation of the sound sources of the microphone in the antrum auris so that the microphone in the outer casing of the microphone only picks up outside interference sources of low sound volumes and reduce outside interference with the microphone in the antrum auris. Talking is clear.

Description

Can reduce the earphone of interference

Technical field

The utility model relates to a kind of earphone, particularly a kind of earphone that reduces interference.

Background technology

The design of existing mobile phone 33 earphones 3 as shown in Figure 5, it is a specified distance below the loudspeaker 31 of earphone 3, other establishes a microphone 32, reach the function of sending and receiving words, but this design is when conversation, the influence of external environment when described microphone 32 will be conversed and the sound that sends is interfered, make the quality of giving orders or instructions not good, and when conversation, often described microphone 32 must be furthered in mouth, can make to be subjected to words side to hear more clearly sound, also inconvenient in the use.

The design of another kind of existing earphone 4 as shown in Figure 6, it is a kind of wireless earphone 4, though it saves the restriction of transmission line, the high volume of its price is big, and its design also is the main body rear that has an adjutage 41, be provided with loudspeaker 42, and, be provided with a microphone 43, but constitute the state of sending and receiving words in the end of adjutage 41, and be hooked in ear top by a hook 44, but this earphone 4 equally also has and disturbed and bulky shortcoming by environmental noise.

The design of another existing earphone as shown in Figure 7, it mainly is provided with a microphone 54 at 53 places, disposal area of protecgulum 52 central authorities of earphone outer covering 5 front end settings, and make microphone 54 be positioned at loudspeaker 51 anterior position places, and then described microphone 54 is located at be not subjected in the quietly duct of external interference and accepts part by the sound wave that produces in the duct, with isolated extraneous interference source of sound, but this design all is positioned at the same airtight chamber of duct because of its microphone 54 and loudspeaker, very easily the sound that is produced because of loudspeaker 51 is received by microphone 54 and produces echo, though but can improve the echo problem as if sensitivity reduction with described microphone 54, but can influence the quality of giving orders or instructions, and then make the side talked about to know the sound of hearing the calling party.

Summary of the invention

Main purpose of the present utility model is that one group of microphone is separately positioned on the shell of the online and earphone of the preceding square shaft of loudspeaker, by described group of microphone with the mutual auxiliary sound state that is subjected to, to pick up the source of sound that accumulates higher volume than the sound source of amount of bass separately, and make the described tone sense degree that is subjected to that is arranged on the microphone on the earphone outer covering be set in the compensation to pick up in the low slightly scope as the microphone source of sound in the aforementioned described duct, and then only pick up external interference source than amount of bass, and make conversation more clear, and then speech quality is significantly improved.

In order to achieve the above object, the technical solution adopted in the utility model is: comprise shell, loudspeaker, protecgulum and one group of microphone, it is characterized in that:

In the shell of earphone, be provided with loudspeaker, simultaneously in the protecgulum central authorities that are provided with a plurality of holes of earphone outer covering front end, form the disposal area of a central tool hole, in described disposal area, be provided with a microphone, a microphone is set on the shell of earphone;

And by this design, when making earphone fill in duct in ear, its loudspeaker and microphone will all be entered in earhole, and then a microphone wherein is located at be not subjected in the quietly duct of external interference and accepts part by the sound wave that produces in the duct, simultaneously accept the sound that first speaker is sent by face by the described microphone of being located at earphone outer covering, in described group of microphone one, one is outer with the auxiliary sound state that is subjected to mutually, to pick up the source of sound that accumulates higher volume than the sound source of amount of bass separately, and the described microphone of mat only picks up the characteristic than the external interference source of amount of bass, and produces jointly and reduce external interference and make conversation effect more clearly with microphone in the described duct.

Another technical scheme that the utility model adopts is: comprise shell, loudspeaker, protecgulum, one group of microphone and a wireless receiving radiating circuit, it is characterized in that:

In earphone outer covering, be provided with wireless receiving radiating circuit and battery, be provided with a protecgulum with a plurality of holes in earphone outer covering the place ahead group, form the disposal area of a central tool hole on the described protecgulum, in described disposal area, be provided with a microphone, a microphone is set on the shell of earphone;
