Description

PlayGear Stealth

Technical field

The utility model relates to a kind of earphone, particularly has the common PlayGear Stealth of transmission line.The utility model belongs to listening device and audition auxiliary equipment technical field.

Background technology

PlayGear Stealth is called for short headset usually, and it is a kind of earphone that is used in human body hearing organ inside.The advantage that it is main: (1) reduces ambient noise to the interference of music.The environment of a sealing that (2) provides has significantly reduced the leakage sound.

Common PlayGear Stealth mainly is made of earphone heads and the sender that is positioned on the earphone heads.As the open PlayGear Stealth of: Chinese patent notification number CN201479349U, it comprises housing and loudspeaker, is the front with the sounding face of earphone, and the housing front portion is cock body, and the cock body front end face is provided with some vocal holes.

It is fixing that existing PlayGear Stealth mainly relies on the clamping of earhole in people's ear and tragus to realize, it is mainly not enough: phenomenon easily drops (1); (2) long periods of wear, earhole and tragus muscle can aches.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of PlayGear Stealth is provided, and it solves easily dropping of existing in prior art and wears problems such as uncomfortable.

For realizing above-mentioned technical purpose, the utility model is by the following technical solutions: a kind of PlayGear Stealth, and include earphone heads and be positioned at main sender on the earphone heads, the back upper place of described earphone heads is provided with annular ring, the angle of annular ring and vertical line is α, 20 °≤α≤50 °.

Because establish the annular ring that has certain angle in the back upper place of earphone heads, annular ring will be against in the crura of antihelix lower grooves in people's ear.So, on the one hand, annular ring can provide the part support force, and earphone is difficult for dropping from people's ear, wear more firmly, and on the other hand, the part support force that annular ring provides will be alleviated the stressed of earhole and tragus, wear more comfortable.

Further, described main sender is positioned on the edge of earphone heads, and the end face of described earphone heads middle part is provided with time sender.

Further again, described earphone heads is oval earphone heads, and described main sender is positioned at oval two focus extended lines and oval outer edge position of intersecting point.

Further again, annular ring is the elliptical perimeter circle that side view is serpentine.

Benefit after the employing optimal technical scheme:

(1) main sender is located on the edge of earphone heads, prevents that effectively the sound that sender spreads out of from being stopped by the concha auriculae of people's ear, more convenient transmission sound.

(2) use oval-shaped geometry, main sender is placed in the earhole more easily, increase time sender, acoustical quality is better.

(3) side view is the elliptical perimeter circle of serpentine structure, can better provide support power.

The utility model is worn firmly, and is comfortable.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is done explanation in further detail.

Embodiment

Shown in Fig. 1～4, a kind of PlayGear Stealth, constituted by left earphone and right earphone, for arbitrary earphone wherein, it includes earphone heads 2 and the main sender 3-1 that is positioned on the earphone heads, the back upper place of earphone heads 2 is provided with annular ring 1, and annular ring 1 is α with the angle of vertical line, 20 °≤α≤50 °.

After adopting technique scheme, annular ring 1 will be against in the crura of antihelix 4-1 lower grooves in people's ear 4.So, on the one hand, annular ring can provide the part support force, and earphone is difficult for dropping from people's ear, make and wear firmly, and on the other hand, the part support force that annular ring 1 provides will be alleviated the stressed of earhole 4-2 and tragus 4-3, make comfortable wearing.

It is fixing that existing earphone mainly relies on the clamping of earhole 4-2 in people's ear and tragus 4-3 to realize, main sender 3-1 is positioned on the front end face of earphone heads.Main sender 3-1 this moment concha auriculae 4-4 position in people's ear 4, the sound that main sender 3-1 spreads out of imports earhole 4-2 into by the feedback of concha auriculae 4-4.

For improving the transmission sound effect, shown in Fig. 1～4, the inventor proposes corrective measure on the basis of the above: main sender 3-1 is located on the edge of earphone heads 2.As shown in Figure 5, the sound that spreads out of of main sender 3-1 can directly import earhole 4-2 into.The end face middle part of earphone heads 2 increases time sender 3-2, and the sound that inferior sender 3-2 spreads out of imports earhole 4-2 into by the feedback of concha auriculae 4-4, and acoustical quality is better.

Existing earphone heads generally is circular, and main sender 3-1 can be positioned on the edge of circular earphone heads.For making main sender 3-1 more near earhole 4-2, and even can place in the earhole 4-2, shown in Fig. 1～4, the inventor further proposes corrective measure on the basis of the above: earphone heads 2 adopts oval earphone heads, ellipse has two focal point F 1, F2, and main sender 3-1 is positioned at oval two focus extended lines and oval outer edge position of intersecting point.

For better support force can be provided, shown in Fig. 3 or 4, the inventor further proposes on the basis of the above: annular ring 1 preferred side view is the elliptical perimeter circle of serpentine.

During normal the use, as shown in Figure 5, the elliptical perimeter circle of serpentine can be against in the crura of antihelix 4-1 lower grooves in people's ear, and the main sender 3-1 that is positioned on the oval earphone heads edge can easilier place earhole, and wear more firm, comfortable.

The utility model left side earphone and right earphone are symmetrical structure, the use state diagram of left earphone and Fig. 5 symmetry.

The utility model is not limited to above-described embodiment, and the technical scheme that all employings are equal to or the equivalence replacement forms all falls into the protection range that the utility model requires.
