Abstract

An earphone with a bass tuning function is provided with a shell and a speaker that is arranged inside the shell, wherein, a resonance space that is used for the speaker to generate the frequency resonance is arranged inside the shell, and the shell is provided with a gap that is communicated with the resonance space; the earphone is also provided with an adjusting cover that can move corresponding to the shell and can cover the gap, and the adjusting cover is provided with a through hole with a given area; when the position of the adjusting cover is changed corresponding to the shell, the through hole is correspondently communicated with the given position of the gap, so that an air flow passage with different areas of the cross section can be generated, and the air flow passage can influence the flow speed of the air entering into and outside the resonance space, thereby can adjust the low-frequency resonant sound performance.

Description

A kind of earphone of tool bass regulatory function

[technical field]

This creation is a kind of earphone with bass regulatory function, refers to a kind of earphone person of the tool bass regulatory function that does not need the extra electron circuit and can mechanically adjust especially.

[background technology]

Because it is day by day small and exquisite to play the volume of Portable playing device of digital single music file peace (for example MP3 archives etc.), and internal storage also day by day increases, can store quite a large amount of music archive, therefore quite receive an acclaim, and in order to present better broadcast tonequality, good earphone is indispensable accessory, but be known as earphone on the market with low sound function, its inside is provided with toot the space altogether for low-frequency sound resonance, but can't adjust with user's hobby, therefore only can come low-frequency signal is adjusted by the internal circuit design of Portable playing device, adapt to the different hobbies of hearer of listening to reach to the bass power, in case but the Portable playing device there is no when adjusting the low-and high-frequency signal function, listen the hearer and can only change the Portable playing device or be forced to and accept existing earphone, desirable not to the utmost in the use.

[summary of the invention]

According to above-mentioned, the main purpose of this creation is, provides a kind of the need to be adjusted and the direct earphone person of adjustment bass performance on earphone by the Portable playing device.

For reaching above-mentioned purpose, the earphone of the tool bass regulatory function of this creation includes the loud speaker that a housing and is positioned at this housing, and this enclosure interior is formed with a toot space altogether for this loud speaker generation frequency resonance, this housing is formed with a slit that is connected with this common toot space, and this earphone has more an adjustment lid that can move and cover this slit with respect to this housing, this adjustment lid has a perforation of fixed-area, with the change of this housing relative position this perforation is communicated with by this adjustment lid accordingly with the ad-hoc location in this slit, and then produce one of cross-sectional area difference air flow channel accordingly, with influence air pass in and out this altogether toot space flow velocity and adjust the sound performance of low-frequency resonance.

[description of drawings]

First figure is one of the earphone of this a creation tool bass regulatory function preferred embodiment decomposing state schematic diagram.

Second figure is this preferred embodiment combination back schematic appearance.

The 3rd figure is this preferred embodiment part cross-sectional schematic.

The 4th figure is that one of view is adjusted in this preferred embodiment.

The 5th figure is two of this preferred embodiment adjustment view.

[embodiment]

Relevant this creation for reach above-mentioned purpose, feature has been adopted technological means and effect thereof, exemplify now one wait upon embodiment and the cooperation below graphic being described as follows:

Consult first figure to the, three figure, the preferred embodiment of one of the earphone of the tool bass regulatory function of this creation is in order to inserting in the human body ear so that electric signal is converted to sound, and it includes loud speaker (figure does not show) and that a housing 1, is positioned at this housing 1 and adjusts and cover 2.

This housing 1 inside is formed with a toot space 10 altogether that produces frequency resonance for this loud speaker, and this housing 1 terminal centre has a pivoted hole 11, be the center and is formed with one and is total to the slit 12 that toot space 10 is connected with being somebody's turn to do with this pivoted hole 11.In this example, the width in this slit 12 is the curved lines of rabbet joint that are drops by an end towards other end convergent.

These adjustment lid 2 central authorities have a jack-post 21, in order to snap in this pivoted hole 11, make adjustment cover 2 and can rotate and cover this slit 12 with respect to this housing 1, this adjustment lid 2 is provided with a circular perforations 22 of fixed-area, relatively rotate and make the relative position change with this housing 1 by this adjustment lid 2, this perforation 22 will be communicated with the ad-hoc location in this slit 12 accordingly.

By above-mentioned structure, the user only need rotate to adjust covers 2, perforation 22 is positioned on the diverse location in slit 12 accordingly, as the 4th figure, when perforation 22 ends that 12 width are bigger towards the slit move, it is bigger to produce cross-sectional area accordingly, one of flow velocity is very fast air flow channel, the 5th figure and for example, when perforation 22 towards the slit when the less end of 12 width moves, it is less then can to produce cross-sectional area accordingly, one of flow velocity is slower air flow channel, therefore the different air flow channel of flow velocity can influence air and passes in and out this toot space 10 and adjust the sound performance of low-frequency resonance altogether, and then carry out optimal adjustment by the user, need not rely on the circuit adjustment of Portable playing device fully.

In addition, this housing 1 now has a stopper slot 13, this adjustment lid 2 then is provided with this adjustment lid 2 and moves and stretch into a projection 23 in this stopper slot 13, this stopper slot 13 of mat limits the displacement of this projection 23 to cooperate this slit 12 length, and then limit this adjustment lid 2 angles with respect to this housing 1 rotations, make outside the 22 unlikely scopes that move to slit 12 of boring a hole.

Comprehensive the above, this creation [earphone of tool bass regulatory function] really can be by above-mentioned structure, reach the effect of expection, and do not see the also unexposed use of publication before the application, meet the novelty of novel patent, improve and meet important documents such as industry applications, so propose patent application in accordance with the law.And the above only is the embodiment of this creation, and simple and easy modification that the spirit of Fan Yiben creation is done and equivalence change design, should be covered by in the following claim.

Claims

1, a kind of earphone of tool bass regulatory function, be used to insert in the human body ear so that electric signal is converted to sound, this earphone includes the loud speaker that a housing and is positioned at this housing, and this enclosure interior is formed with a toot space altogether for this loud speaker generation frequency resonance, is characterised in that altogether:

This housing is formed with a slit that is connected with this common toot space, and this earphone has more an adjustment lid that can move and cover this slit with respect to this housing, this adjustment lid has a perforation of fixed-area, with the change of this housing relative position this perforation is communicated with by this adjustment lid accordingly with the ad-hoc location in this slit, and then produce one of cross-sectional area difference air flow channel accordingly, with influence air pass in and out this altogether toot space flow velocity and adjust the sound performance of low-frequency resonance.
