Abstract

The utility model relates to a switching device of an electronic component, in particular to an earphone switching head, comprising a plug part of 2.25 mm and a jack part of 3.25 mm. The copper wire of the plug part is connected with a groundwire post head of the jack part; the red line and the blue line of the plug part are respectively connected with the positive post head and the negative post head of the jack part. Besides, the plug part can be 3.25 mm and the jack part can be 2.25 mm. The utility model mainly solves the technical problem that the prior earphone plug and jack with two specifications of 2.25 mm and 3.25 mm can not be matched with each other; the utility model can lead to that a pair of earphones is applicable to a plurality of portable electronic products.

Description

A kind of earphone adapter

Technical field

The utility model relates to the switching device of electronic devices and components, particularly a kind of earphone adapter.

Background technology

Along with the fast development of electronic technology, the daily life that increasing portable type electronic product has entered into us comes, and these electronic products comprise MP3, MP4, multimedia handset, or even early stage portable radio (Walkman).These products all have Audio Processing function preferably, enjoy for people provide beautiful music, and the audio output device of these products are exactly an earphone.

Because with the specification complete unity of earphone interface, therefore existing earphone interface does not have 2.25mm and two kinds of specifications of 3.25mm to each electronic product manufacturer, the plug of all size and jack must mate use.Like this, the earphone of any one specification all can't be applicable to the jack of another kind of specification.Therefore, we must provide a kind of switching device, and the plug of two kinds of specifications and jack can be suitable for mutually.

The utility model content

The purpose of this utility model is to provide a kind of earphone adapter, and the headset plug and the jack that mainly solve existing 2.25mm and two specifications of 3.25mm can't mate suitable technical problem mutually, and it can make a set of headphones be applicable to a plurality of portable type electronic products.

For achieving the above object, the technical solution of the utility model is:

A kind of earphone adapter, it is characterized in that: it comprises the female part of a male component and the 3.25mm of a 2.25mm, the copper cash of this male component connects the earth terminal of female part, and the red line of this male component and blue line are connected the positive terminal and the negative terminal of female part respectively.

Described earphone adapter is characterized in that: described male component is the 3.25mm specification, and female part is the 2.25mm specification.

Described earphone adapter is characterized in that: have a housing, this male component and female part are arranged in the housing, and the plug of this male component and the jack of female part expose housing.

By technique scheme, the beneficial effects of the utility model are:

The utility model can be realized the conversion of the earphone connected structure of 2.25mm and two specifications of 3.25mm, and therefore, a set of headphones can be applied to multiple electronic product.

Embodiment

See also Fig. 1, it is the structural representation of a kind of earphone adapter of the utility model.As shown in the figure: it comprises the female part 2 of a male component 1 and the 3.25mm of a 2.25mm, the copper cash 13,14 of this male component 1 connects the earth terminal 23 of female part 2, and the red line 11 of this male component 1 and blue line 12 are connected the positive terminal 21 and the negative terminal 22 of female part 2 respectively.Can realize that by said structure 3.25mm specification earphone is diverted to the electronic product with 2.25mm specification earphone jack.

Same syndeton when described male component 1 is the 3.25mm specification, when female part 2 is the 2.25mm specification, can realize that 2.25mm specification earphone is diverted to the electronic product with 3.25mm specification earphone jack.

In addition; this adapter can have a housing 3; this male component 1 and female part 2 are arranged in the housing 3, and the jack of the plug of this male component 1 and female part 2 exposes housing 3, and the major function of this housing 3 is exactly protection male component 1 and female part 2 and the connecting line between them.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
