Description

In-Ear Headphones

Technical field

The utility model relates to a kind of aural headphone that involves in, and particularly relates to the adjustable In-Ear Headphones of a kind of bass.

Background technology

In-Ear Headphones shows and outstanding soundproof effect because of its outstanding Portability, high-quality sound, and very popular.In-Ear Headphones generally comprises earphone case, sound-producing device and ear muff.Sound-producing device is located in the earphone case, and and earphone case between form resonant cavity.Existing In-Ear Headphones is when adjustment low-frequency range sound; Usually in the resonant cavity of earphone, put a damping thing,, change the damping of earphone monomer with the pressure in the control resonant cavity; And then reach the sound and the sound press (volume) of control bass frequencies section; Be beneficial to and high pitch frequency range sound coupling, but ordinary consumer usually can't arbitrary replacing damping thing, be difficult to satisfy user's demand.For catering to the high instructions for use of People more and more, the adjustable In-Ear Headphones of bass arises at the historic moment.The adjustable In-Ear Headphones of existing bass generally comprises earphone case, sound-producing device, ear muff and tuning device.Sound-producing device is located in the earphone case, and and earphone case between form resonant cavity.Offer sound regulating hole on the earphone case; Tuning device is movable to be installed on the earphone case, through the position relation of adjustment tuning device and sound regulating hole, with the gas output and the flow velocity of adjustment bass; Thereby change the LF-response curve of bass, and then obtain different auditory perceptions.

But, the tuning device complex structure of the adjustable In-Ear Headphones of above-mentioned existing bass, manufacturing cost is high.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of simple in structure, the adjustable In-Ear Headphones of the bass of low cost of manufacture.

For realizing above-mentioned purpose, the utility model provides a kind of In-Ear Headphones, comprises a headset main body and an adjustment ear muff.Headset main body has an earphone case; Be formed with a sound chamber in the earphone case, earphone case one end convexes with a sound guide tube, and sound guide tube is provided with at least one bleeder port; The sound guide tube outside is cannelure and outer annular groove in being concaved with of interval, and sound chamber and sound guide tube are interconnected.The adjustment ear muff movably is sheathed on the headset main body, has an ear muff principal part, and ear muff principal part inboard is provided with a sleeve; Jacket casing is located on the sound guide tube; The sleeve inboard convexes with a holding part, and holding part movably is held in interior cannelure or the outer annular groove with adjusting ear muff, makes that the bleeder port on the earphone case seals or connection with extraneous; Thereby change the pressure in the sound chamber, and then can reach the purpose of adjustment audio.

As stated; The utility model In-Ear Headphones is held in interior cannelure or the outer annular groove through the holding part of adjustment adjustment ear muff; Thereby make the bleeder port on the earphone case seal or connection, thereby change the pressure in the sound chamber, and then can reach the purpose of adjustment audio with extraneous; Simple in structure, low cost of manufacture.

Embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with execution mode and conjunction with figs. and give explanation.

See also Fig. 1, the utility model In-Ear Headphones comprises headset main body 1 and adjustment ear muff 2.

In the present embodiment; Please continue and consult Fig. 1 and Fig. 2; Headset main body 1 has an earphone case 11, is formed with a sound chamber 12 in the earphone case 11, and earphone case 11 1 ends convex with a sound guide tube 13; Sound guide tube 13 is provided with at least one bleeder port 14, and sound guide tube 13 outsides are cannelure 151 and outer annular groove 152 in being concaved with of interval.In the present embodiment, sound guide tube 13 1 sides in bleeder port 14 promptly is arranged on the cannelure 151.

Please continue and consult Fig. 1 to Fig. 3; Adjustment ear muff 2 movably is sheathed on the headset main body 1; Adjustment ear muff 2 has an ear muff principal part 21, and ear muff principal part 21 inboards are provided with a sleeve 22, and sleeve 22 is sheathed on the sound guide tube 13; Sleeve 22 inboards convex with a holding part 23, and holding part 23 movably is held in interior cannelure 151 or the outer annular groove 152 with adjustment ear muff 2.

When the utility model In-Ear Headphones used, sound chamber 12 was interconnected with sound guide tube 13, when needs adjustment audio; Because adjustment ear muff 2 softnesses, yielding material characteristic; Rotatable and extract adjustment ear muff 2, make adjustment ear muff 2 skid off in cannelure 151 and being held in the outer annular groove 152, make that the bleeder port 14 on the earphone case 11 is communicated with extraneous; Thereby change the pressure in the sound chamber 12; Reaching the purpose of adjustment audio, and can select to place the damping thing of processing by the material of flexible and compressible change density such as sponge, elastoplast, weaving etc. (figure does not show) in the bleeder port 14, and then improve the effect of adjustment bass.

Please continue and consult Fig. 4, it is that In-Ear Headphones regulates the characteristic variations curve chart of bass, and intercepting the frequency range of human auditory system (20HZ～20KHZ), the bleeder port 14 of the utility model In-Ear Headphones when different shielding status to the reflection of sound.When in the holding part 23 of adjustment ear muff 2 is held in, blocking bleeder port 14 in the cannelure 151, the earphone air leakage is little, low loudness of a sound, and the frequency response curve of its bass shows for curve I among the figure; Move adjustment ear muff 2 holding part 23 is held in when exposing bleeder port 14 in the outer annular groove 152, the earphone air leakage is big, and a little less than the bass, the frequency response curve of its bass shows for curve II among the figure.

In sum; The utility model In-Ear Headphones is held in interior cannelure 151 or the outer annular groove 152 through the holding part 23 of adjustment adjustment ear muff 2; Thereby make the bleeder port 14 on the earphone case 11 seal or connection, thereby change the pressure in the sound chamber 12, and then can reach the purpose of adjustment audio with extraneous; Simple in structure, low cost of manufacture.

Above-mentioned detailed description is for being directed against a kind of preferred embodiment explanation of the utility model; But this embodiment is not in order to limit the claim of the utility model; All other do not break away from the equalization of being accomplished under the skill spirit that the utility model discloses to be changed and modifies change; All should be contained in the claim that the utility model contains, for example bleeder port 14 also can be arranged on sound guide tube 13 1 sides on the outer annular groove 152.
