Description

Earphone front cavity with sound outlet pipe with multi-sound-outlet hole structure

Technical Field

The utility model relates to an earphone earplug field especially relates to a go out sound pipe and have many play sound hole structure earphone front chamber.

Background

Earphones and earplugs are portable audio equipment for modern people to go out, and along with improvement of living standard, the demand of people for the tone quality of the earphones and the earplugs is higher and higher nowadays. The sound quality of the earphone and the earplug mainly depends on the structural design of the front cavity, and the design of the conduit is an important component in the structural design of the front cavity.

As shown in fig. 1, a speaker 2 and a front cavity sound guide tube 4 are respectively disposed at two ends of a front cavity 1 of the earphone, and through holes 3 are disposed on the circumferential surface of the front cavity 1 of the earphone. As can be seen from fig. 1, the front cavity of the conventional earphone or earplug has a single structural design, which results in the technical problem in the prior art that the frequency response curve and the sound quality of the earphone or earplug are seriously homogenized.

SUMMERY OF THE UTILITY MODEL

Objects of the invention

For solving the technical problem who exists among the background art, the utility model provides a go out sound pipe has many play sound hole structure earphone front cavities, and the bellied equipartition sets up a plurality of first play sound holes on global, changes the area of going out the sound hole to change the resonance and the resonant frequency of earphone, each frequency channel of earplug, in order to adjust out the frequency response curve and the tone quality that accord with the demand.

(II) technical scheme

The utility model provides an earphone front cavity with a sound outlet pipe and a structure with a plurality of sound outlet holes, which comprises a body, a loudspeaker component and a sound guide pipe; the loudspeaker assembly and the sound guide pipe are respectively arranged at two ends of the body;

the end part of the sound guide tube is provided with a cylindrical bulge, and the interior of the bulge is hollow; a plurality of first sound outlet holes are uniformly distributed on the circumferential surface of the protrusion.

Preferably, one end of the bulge, which is far away from the sound guide tube, is provided with a second sound outlet hole.

Preferably, the first sound outlet hole is a strip-shaped hole or a circular hole.

Preferably, the circumferential surface of the body is provided with a through hole.

Preferably, the horn assembly is in snap-fit connection with the upper end of the body.

In the utility model, a horn component is arranged on the body, the end part of the sound guide tube is provided with a cylindrical bulge, and the interior of the bulge is hollow; a plurality of first sound outlet holes are uniformly distributed on the circumferential surface of the protrusion, the area of the sound outlet holes is changed, and therefore the resonance and the resonance frequency of each frequency band of the earphone and the earplug are changed, and the frequency response curve and the tone quality meeting the requirements are adjusted.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-4, the sound outlet duct of the present invention has a front cavity of an earphone with a structure having multiple sound outlet holes, which includes a main body 1, a speaker assembly 2 and a sound guide tube 4; the horn component 2 and the sound guide tube 4 are respectively arranged at two ends of the body 1;

the end part of the sound guide tube 4 is provided with a cylindrical bulge 7, and the bulge 7 is hollow; a plurality of first sound outlet holes 5 are uniformly distributed on the circumferential surface of the bulge 7.

In the utility model, a horn component 2 is arranged on a body 1, a cylindrical bulge 7 is arranged at the end part of a sound guide tube 4, and the interior of the bulge 7 is hollow; a plurality of first sound outlet holes 5 are uniformly distributed on the circumferential surface of the protrusion 7, the area of the sound outlet holes is changed, and therefore the resonance and resonant frequency of each frequency band of the earphone and the earplug are changed, and the frequency response curve and the tone quality meeting the requirements are adjusted.

In an alternative embodiment, the end of the protrusion 7 away from the sound guiding tube 4 is provided with a second sound outlet hole 6 to increase the sound quality effect and ensure that the best sound quality is achieved.

In an optional embodiment, the first sound outlet 5 is a strip-shaped hole or a circular hole, and the shape of the hole is selected according to the size of the body 1, so that the sound outlet effect is ensured.

In an optional embodiment, the circumferential surface of the body 1 is provided with through holes 3, so that ventilation is facilitated, and a good heat dissipation effect is achieved.
