The beneficial effects of the utility model are: the utility model is by external battery, and utilizes the battery as weatherseal, effectively
The sound for collecting user, allow sound to filter out sound of the wind when picking up, increase voice recognition rate, and external battery
Structure can make the heat of battery be not transferred to headset assembly, and heat dissipation performance increases, and simplify earphone internal structure.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model cell apparatus after the stretch.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, abstract and attached drawing), except non-specifically chatting
It states, can be replaced by other alternative features that are equivalent or have similar purpose.That is, unless specifically stated, each feature is only
It is an example in a series of equivalent or similar characteristics.
As shown in Figure 1, including earphone host 7, the side of earphone host 7 is provided with an earplug head 8, is arranged on earplug head 8
There is sound net out, earplug head 8 is filled in in earhole, and earphone host 7 is internally provided with earphone master control borad and earphone horn, earphone loudspeaker
Engaging lug machine master control borad, earphone horn face out the setting of sound net, and the bottom of earphone host 7 is provided with a pedestal 4, pedestal 4
Back one layer of rubber elastic membrane 3 Nian Jie with the back of earphone host, the front end face of rubber elastic membrane 3 is bonded with more than one solid
Determine box 2, the front face open of fixed bin 2, front opening end insertion one lithium battery device 5 of setting, the upper end two of lithium battery device 5
Side respectively opens up a telescopic hole 11, and a telescoping tube 6 is inserted into telescopic hole 11, is formed with out line passage (not inside telescoping tube 6
Diagram), it is logical that the positive and negative polar curve of lithium battery device is inserted into the outlet in telescopic hole and being inserted into inside telescoping tube 6 across fixed bin
In road.
Wherein, as shown in Fig. 2, the top of the telescoping tube 6 of bottom row is weldingly fixed on the lower end surface of top fixed bin 2
On, lithium battery device 5 includes that li-ion cell protection shell and the battery core and protection board that are set in li-ion cell protection shell (are not schemed
Show), charging interface is provided on protection board, and charging interface is located at the outside of battery protection shell, the positive and negative polar curve 9 of lithium battery device
The positive and negative anodes pad solder inside earphone host 7 and with earphone master control borad, the depth etc. of telescopic hole 11 are inserted into across telescoping tube 6
In the length of telescoping tube.When not in use, each lithium battery device splices and is superimposed mutually, reduces volume and length,
Lithium battery device is normally headset assembly in-line power.
Wherein, the bottom of earphone host 7 is provided with call pickup hole 1, and pickup microphone (not shown) is arranged in pickup hole 1,
The signal output end engaging lug machine master control borad of pickup microphone.When outer gas stream is very big, we pull out telescoping tube, so that adjacent lithium
Spacing between cell apparatus becomes larger, and rubber elastic membrane is stretched, the lithium battery device of earphone host lower end surface and bottom it
Between formed a sound chamber, since pickup hole is located at the top position of sound chamber, the collection sound that can more concentrate in this way utilizes bullet
Shielding of the property rubber membrane as air-flow, when not conversing, rubber elastic membrane is not stretched, and will not influence aesthetics.Due to each lithium battery
It is stretched between device, therefore heat dissipation performance can greatly increase.
Positive and negative anodes electricity of the positive and negative power supply line in pull telescoping tube by being influenced, inside telescopic hole in order to prevent
Source line can be set to the structure of spring wire, make the influence of its not Tensile.In addition, wrapping up one layer of rubber in the external of telescoping tube
