Earphone

Technical field

The utility model is related to acoustic product technical field, more particularly to a kind of earphone with wired control box.

Background technology

Earphone is a kind of energy converter, it receives the electric signal that media player or receiver are sent, using close to The component of raising one's voice of ear converts it into the sound wave that can be heard, is that the portable electric appts such as mobile phone, walkman, radio must Indispensable accessory.Earphone includes wired earphone and the wireless headset to communicate with bluetooth, with the development of science and technology, people couple Quality of the life requirement greatly improves, and bluetooth headset has become the daily product of life.

With the development of ear phone technology, newly occurs a kind of line traffic control bluetooth headset in the market, such earphone carries wired control box, can The battery of larger capacity is equipped with, has many advantages, such as that continuation of the journey is lasting, it is easy to operate, it is increasingly becoming the new Pang of people.Line traffic control bluetooth ear Volume adjustment, telephone receiving and the bluetooth connection of machine are realized by the keypress function on wired control box, therefore on wired control box The structure design of button plays critically important effect to wired control box using feel quality, the length in service life.

At present, there are mainly two types of forms for the press-key structure on common wired control box：

The first, is equipped with a flexible gasket, passes through between the button on press-key structure and PCB (wiring board) on wired control box The squeezing action of flexible gasket realizes the function of button.The drawback is that with the use of button, the elasticity of flexible gasket can reduce Comparatively fast, feel is deteriorated therewith, and key shape design feel is bad.

Second, simple mechanical key structure, the button on button and PCB on wired control box contacts directly, and relies on The elasticity of button in itself on PCB is sprung back.The drawback is that the service life is shorter, feel is poor.

Utility model content

For disadvantages described above, the purpose of this utility model is to provide a kind of earphone, the wired control box key press hand of this earphone Feel, user experience effect is good.

To achieve the above object, the technical solution of the utility model is：

A kind of earphone including component and the earphone cable that is electrically connected with the component of raising one's voice of raising one's voice, connects on the earphone cable There is wired control box, the wired control box includes combined upper cartridge body and lower box body, and the upper cartridge body is surrounded with the lower box body Space in contain wiring board, the position that the wiring board is corresponded on the upper cartridge body is equipped with press-key structure；Its feature exists In the press-key structure includes flexible panel and the rigid support frame being incorporated on the inside of the panel, the panel Inside is equipped with button column, and the button column can make the circuit turn-on on the wiring board when pressing the panel, performs The function of corresponding button.

Wherein, the upper cartridge body is equipped with notch, and the press-key structure is mounted on the indentation, there, and the button column passes through The notch triggers the electric connecting part on the wiring board so that the circuit turn-on.

Wherein, the button column is equipped with multiple, and support frame as described above is equipped with and is used to support between the adjacent two button column The crossbeam at position, the inside of the panel are equipped with to house the storage tank of the crossbeam.

Wherein, the inside of the panel corresponds to the position of each button column and is equipped with installation ringwall, and each button column consolidates It is scheduled on the corresponding mounting ring within the walls.

Wherein, the button column and the installation ringwall interference fit, the side of the button column, which is equipped with, goes what material was formed Planar structure.

Wherein, the side of the installation ringwall is equipped with resilient structures.

Wherein, the resilient structures include the elastic rib for being radially arranged on the installation ringwall side.

Wherein, the resilient structures include being arranged on the elastic construction of the installation ringwall opposite sides, institute in diffusion type Elastic construction is stated as step structure, the step structure is outwards raised step by step by the root of the installation ringwall.

Wherein, the outside of the panel corresponds to the button portion that each position for installing ringwall is respectively equipped with protrusion, described Round-corner transition is used between the end face of button portion and its side.

Wherein, the panel is integrally formed with support frame as described above by two-shot molding process, and support frame as described above is equipped with and grabs The groove of glue is equipped with the convex block inserted in the groove on the panel accordingly.

After employing above-mentioned technical proposal, the beneficial effects of the utility model are：

Since the press-key structure of the utility model earphone line control box includes flexible panel and is incorporated on the inside of panel Rigid support frame, the position of the inside corresponding line plate of panel be equipped with from outside pressing panel when can touch so that wiring board On circuit turn-on button column.The supporting rack of hard can counter plate play a supporting role, can prevent resilient panel collapse and The false triggering situation of more buttons can improve the reliability of wired control box；Resilient panel have elasticity, after pressing force removes its from Body has resilience, and the elastic force rebound that need not fully rely on the electric connecting part on wiring board for turning circuit resets, and subtracts The light fatigue strength of electric connecting part can improve the service life of electric connecting part.Panel has certain bullet in itself simultaneously Property and flexibility, the pressing good hand touch of user, experience effect are good.

In conclusion the wired control box operating handle that the utility model earphone solves earphone in the prior art is poor, the longevity is used The technical problems such as short are ordered, the wired control box service life of the utility model earphone is long, and reliability is high, and operating handle is good, experience effect It is good.
