Abstract
The utility model discloses an earphone, which comprises a sound emitting source and a volume regulating device. The volume regulating device comprises a noise sensing part and a control part connected with the noise sensing part, the control part is connected with the sound emitting source, the noise sensing part senses noise of the external environment and generates electric signals and provides the electric signals to the control part, and the control part regulates volume of the sound emitting source. The contact position of the earphone and an ear is covered by a silicon gel strip, so that discomfort of a user caused by pressure is reduced. Sounds are transmitted to the periphery of the ear firstly by the aid of a tubular connecting rod of the earphone and then are transmitted to cochlea, so that direct stimulation to auditory nerves is reduced. The earphone can sense intensity of external noise and regulate volume automatically by the aid of a sound control element, and regulating values are constantly kept within a range harmless to the auditory nerves.
Description
Technical field
The utility model relates to a kind of earphone.
Background technology
Existing on the market earphone species is broadly divided into 4 kinds, is wear-type respectively, and is In-Ear, ear type, supra-aural.Every kind of earphone all has advantage and drawback separately.Its sound source is too near apart from cochlea though the earphone of ear type can have good appreciation effect, and long-term use very easily causes the damage of hearing.Supra-aural then can not well be eliminated the interference of external noise for sound.And wear-type and In-Ear shortcoming arranged respectively also.There is not a perfect product that can remedy above-mentioned shortcoming and can develop above-mentioned advantage simultaneously on the market.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of novel earphone is provided.
The technical solution of the utility model comprises a kind of earphone, it comprises sound generation source and volume adjustment device, this volume adjustment device comprises noise induction parts and the control assembly that links to each other with these noise induction parts, this control assembly links to each other with this sound generation source, wherein these noise induction parts are responded to external environmental noise and are generated the signal of telecommunication, and the signal of telecommunication offered this control assembly, this control assembly is regulated the volume of sound generation source.
Wherein, these noise induction parts comprise capacitive electret microphone.
Wherein, this earphone also comprises two earmuffs and the support that is connected these two earmuffs, also is provided with the tubulose connecting rod in this support, wherein this sound generation source be located on this tubulose connecting rod, between these two earmuffs.
Wherein, this earmuff is placed outward and is provided with silica gel strip.
Positive progressive effect of the present utility model is: the contact position at earphone and ear covers with silica gel strip, reduces the sense of discomfort for the user that produces because of pressure; By earphone tubulose connecting rod with transmission sound around ear, and then be passed to cochlea, reduced direct stimulation to auditory nerve; Utilize the acoustic control original paper to reach the purpose of perception ambient noise size and automatic regulating volume size, its change value perseverance is in in the harmless magnitude range of auditory nerve.

Embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is elaborated.
As shown in Figure 1, the structural representation of the utility model one embodiment illustrates the structure of earphone 100.Earphone 100 comprise support 110, respectively be located at these support 110 both sides two earmuffs 120, connect the tubulose connecting rod 130 of these two earmuffs 120 and be located on this tubulose connecting rod 130 and the sound generation source 200 between these two earmuffs 120.
Wherein the effect of this tubulose connecting rod 130 is that sound with sound generation source 200 passes near the earmuff, and then is perceived by the human ear.Therefore, this tubulose connecting rod 130 is made by the material with good sound conductive performance, as metal etc.The material of this support 110 should have good pliability and sturdy and durable, as medical thermoplastic timbering material etc.
As the case may be, this tubulose connecting rod 130 can be an overall structure as shown in Figure 2, or segmental structure as shown in Figure 3 (about two sections).Quantity also can be have one or more.Correspondingly, described sound generation source 200 can have one or more, can one the corresponding tubulose connecting rod 130 of sound generation source, also can sound generation source 200 corresponding above tubulose connecting rods 130, or above sound generation source 200 corresponding tubulose connecting rods 130.For example, for mono headset, have a sound generation source 200 and a tubulose connecting rod 130 (can be integral type, also can be segmented).For dual-channel headphone, can have two sound generation source and segmented (about) the tubulose connecting rod, thereby different left and right acoustic channels sound are sent to left and right sides ear.Equally, multi-sound-channel earphone can be by that analogy.
This earphone 100 also comprises volume adjustment device, and itself and this sound generation source 200 is electrically connected to regulate the volume of this sound generation source 200.This volume adjustment device comprises noise induction parts and the control assembly that links to each other with these noise induction parts.These noise induction parts can be acoustical-electrical transducer spares, and as capacitive electret microphone, this kind condenser microphone is by metallic plate, and elements such as vibrating diaphragm and back pole plate are formed.A plating nickel of vibrating diaphragm, metal level and back pole plate form a direct capacitance.This capacitances in series will produce displacement when vibrating diaphragm is subjected to the acoustic wave action masterpiece time spent in the circuit that DC power supply and load resistance are arranged, the direct capacitance that has formed between vibrating diaphragm and pole plate will change along with the variation of distance.Therefore produce the signal of telecommunication relevant with sound.This control assembly is regulated the volume of this sound generation source according to the variation of this signal of telecommunication.Fig. 4 is the principle schematic of this electret microphone, and the operation principle of electret microphone is as a kind of existing technology, so do not repeat them here.
In addition, by adopting design that ear is wrapped quilt entirely to drop to minimum to the influence of sound external noise.Place at earmuff 120 outer, cover with silica gel strip 140, reduce the sense of discomfort that produces because of pressure for the user with the contact position of ear.
Although the utility model is described according to its preferred implementation, there are the change, displacement and the various substitute equivalents that fall in the utility model scope.Here the example that provides only is illustrative, rather than to restriction of the present utility model.
