Abstract
The utility model discloses a disappear and make an uproar, separate earphone cavity of making an uproar, including being used for installing the earphone sound chamber cavity of loudspeaker and the external cavity that is used for installing electric control assembly such as PCBA plate or battery, through wire guide intercommunication between earphone sound chamber cavity and the external cavity, be connected through two horn wires that pass the wire guide between electric control assembly such as PCBA plate or battery and the loudspeaker, and set up sealing colloid in the wire guide, separate earphone sound chamber cavity and external cavity, form independent cavity separately for in electronic component's in the external cavity among the electric control assembly such as PCBA plate or battery mechanicalness noise, electric current noise were difficult to reach earphone sound chamber cavity, it disappears to reach made an uproar, separate the effect of making an uproar. (B /)
Description
Technical field
The utility model relates to a kind of earphone cavity, particularly a kind of de-noising, every earphone cavity of making an uproar.
Background technology
Along with the development of electronic product, earphone industry also grows up at top speed, head held earphone electric function earphone (bluetooth earphone, wireless game earphone, campaign-styled head held earphone etc.), the extremely hobby of consumer.But along with the development of society, the raising of people's level of production, the requirement of people to earphone quality is more and more higher.The element of some Surface Mounts has small noise in the energising course of work, and these noises are that element finds deformation and the noise that produces in the course of the work, and the frequency-portions of these noises is frequencies of audio section.The size of these noises is most at 18 ~ 25dBSPL.Place, in quiet environment, uses general earphone (PCBA and loudspeaker share cavity), and the noise that mechanical deformation produces occurs when hearing that these work from electronic component easily.And the mechanicalness noise that the size of noise often sends than the electronic component of reality is large, these are all amplified (noise passes through body, reflection repeatedly, concentrates to wait and sound pressure level is improved) by cavity, and the noise found out is exactly the sound amplified by cavity.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of de-noising, every earphone cavity of making an uproar.
The utility model solves the technical scheme that its technical problem adopts:
A kind of de-noising, every earphone cavity of making an uproar, comprise earphone sound chamber cavity and external cavity, be communicated with by wire guide between described earphone sound chamber cavity and external cavity, in described wire guide, be provided with sealed colloid.
Described sealed colloid is a flexible glue.
Described earphone sound chamber cavity is enclosed by earphone case and is formed, and described external cavity is enclosed by external housing and formed, and described earphone case is connected by snap device with external housing.
Described snap device comprises a fastener, described fastener comprises the pothook of at least two, described earphone case offers can for pothook pass clamp hole, described external housing offers the block button hole that can buckle into for pothook, described fastener is arranged in earphone case, during assembling, described pothook end is through clamping hole and being buckled in block button hole.
Described external housing is provided with a connecting seat, and described wire guide is opened in Connection Block.
The beneficial effects of the utility model are: a kind of de-noising, every earphone cavity of making an uproar, comprise for installing the earphone sound chamber cavity of loudspeaker and the external cavity for installing the electrically-controlled components such as PCBA board part or battery, be communicated with by wire guide between described earphone sound chamber cavity and external cavity, the horn wire that PCBA board part or battery etc. pass wire guide by two between electrically-controlled component with loudspeaker is connected, and in described wire guide, sealed colloid is set, earphone sound chamber cavity and external cavity are separated, each self-forming independently cavity, make the mechanicalness noise of the electronic component in external cavity in the electrically-controlled component such as PCBA board part or battery, current noise is difficult to reach in the cavity of earphone sound chamber, reach de-noising, every the effect of making an uproar.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model;
Fig. 3 is application example one of the present utility model;
Fig. 4 is application example two of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 is the structural representation of the utility model specific embodiment, as shown in the figure, a kind of de-noising, every earphone cavity of making an uproar, comprise earphone sound chamber cavity 1 and external cavity 2, described earphone sound chamber cavity 1 is enclosed by earphone case 11 and is formed, described external cavity 2 is enclosed by external housing 21 and is formed, as as shown in Fig. 3 or Fig. 4, earphone sound chamber cavity 1 is for installing loudspeaker 91, outside it, sponges cover 92 or earphone leather sheath also can be set, and in external cavity 2, can be used for installing the electrically-controlled component such as PCBA board part or battery, in figure 3, battery 93 and PCBA board part 94 are installed in external cavity 2, in the diagram, in external cavity 2, PCBA board part 94 is installed, control button, patching jack, draw-in groove etc., certainly, in specific implementation process, assembly in external cavity 2 can according to left and right ear, ear-phone function, headset type, the layouts such as use habit, be not described further at this.
As shown in the figure, be communicated with by wire guide 4 between described earphone sound chamber cavity 1 and external cavity 2, the horn wire that PCBA board part or battery etc. pass wire guide by two between electrically-controlled component with loudspeaker is connected, sealed colloid 5 is provided with in described wire guide 4, earphone sound chamber cavity 1 and external cavity 2 are separated, each self-forming independently cavity, make the mechanicalness noise of the electronic component in external cavity in the electrically-controlled component such as PCBA board part or battery, current noise is difficult to reach the ear passing to people in earphone sound chamber cavity 1 again, the noise of 20HZ ~ 20KHZ is through the isolation of such cavity after tested, can more than sound attenuation 25dB, reach de-noising, every the effect of making an uproar, user is allowed to can't hear the machinery of corresponding electronic component, current noise, the music of better enjoyment high-quality.
As preferably, described external housing 21 is provided with a connecting seat 3, and described wire guide 4 is opened in Connection Block 3, and described sealed colloid 5 is a flexible glue or silica gel.
