As shown in fig. 1 to 5, an elastically worn bluetooth headset earplug includes an inner tube 1 having a sound guide channel 10 and an elastic pad 5 disposed outside the inner tube 1, wherein an opening 101 of the inner tube 1 may extend into an ear canal 3, a rear portion of the inner tube 1 may extend into a sound channel 2 of the headset, and the sound guide channel 10 is gradually expanded from the front to the rear of the opening 101; elastic cushion 5 can lie in 3 extrusion elastic deformation down of duct, and elastic cushion 5 is equipped with deformation portion, deformation portion can be under pressure deformation undergauge.

In the specific installation process, the inner tube 1 of the earplug is directly butted with the sound channel 2 of the earphone, so that the sound loss of the earphone is reduced, and meanwhile, the opening 101 of the sound guide channel 10 is arranged in a frustum shape with expanded diameter, so that the problem that the sound channel 2 is blocked or resonates due to diameter reduction after the inner tube 1 extends into the ear canal 3 can be avoided; meanwhile, the elastic cushion 5 is provided with the deformation part, when the outer wall of the elastic cushion 5 is attached to the inner wall of the auditory canal 3, firstly, the elastic cushion 5 deforms and partially extends into the auditory canal 3, and then the deformation part is extruded to reduce the diameter; therefore, the earplug and the auditory canal 3 are relatively sealed, the displacement between the earphone and the auditory canal 3 is further reduced, the air pressure change generated during the displacement (a relatively sealed cavity is formed between the auditory canal 3 and the earphone at the moment) is avoided, and the fatigue is generated on the auditory canal 3 and the hearing of a user; while avoiding a reduction in audio performance while preventing the accumulation of undesirable static air pressure, i.e., the transfer of the squeezing force of the ear canal 3 to the deformation portion.

In the embodiment of the present invention, the diameter of the sound guiding channel 10 is 1.5mm-1.8mm, and the length of the sound guiding channel 10 is 10mm-20mm. Therefore, the volume of the sound guide channel 10 is about 18-50 cubic mm, and a wider sound wave conduction channel can be effectively formed, so that the sound wave leakage can be avoided, and the sound quality of the earphone is improved.

Specifically, the deformation portion is a pressure relief hole 4, and the pressure relief hole 4 is arranged at the front end of the elastic cushion 5, penetrates through the elastic cushion and can be communicated with the outside. When cushion 5 contacts and extrudees it with duct 3, duct 3 and cushion 5 make duct 3 form relative closed chamber, and 3 internal pressures in the duct are great (extrusion gas and duct 3) this moment, and 3 can produce uncomfortable feelings in the duct this moment, can effectively improve duct 3's leakproofness through the setting of pressure release hole 4, reduce 3 atmospheric pressures in the duct simultaneously, and when cushion 5 was in balanced state with duct 3, pressure release hole 4 was extrudeed and is sealed.

More specifically, the elastic pad 5 is a solid structure or a sheet structure, and the pressure relief hole 4 is arranged in an inclined manner. Fig. 2 shows a sheet structure, fig. 3 shows a solid structure, the actual structure of the earplug is different according to the user's requirement or according to the shape of the earphone, wherein, when a half-in-ear earphone structure is used, the sheet can cover the outer wall, and the length of the inner tube 1 is smaller (just matched with the outlet of the sound channel 2 of the earphone); when the structure of the in-ear earphone is used, a sheet structure may be adopted as well as a solid structure. Of course, in a specific configuration, the pressure relief hole 4 may not be completely closed, for example, as a release of static air pressure in the ear canal 3, for example, a structure similar to a one-way valve may be provided, which may be discharged when the relative air pressure in the ear canal 3 is higher.

Due to the asymmetry of the audio waveform, the static pressure changes along with the time, and if the balanced static pressure is 0, the pressure is increased along with the increase of the time and the influence of the sound wave, the pressure is also larger than 0); especially, in the existing bluetooth headset, the pressure in the inner cavity of the existing bluetooth headset is increased along with the increase of the pressure, and although the elastic cushion 5 can play a good role in buffering and relieving the pressure, the problem of unsmooth pressure relief still exists due to the change of static pressure.

More specifically, the air outlet end of the pressure relief hole 4 is provided with a limiting bump 6, and a dispensing structure can be adopted.

Further, the front end of the elastic pad 5 partially covers the opening 101 of the inner tube 1 or the opening 101 of the inner tube 1 partially protrudes out of the elastic pad 5. Wherein can play better comfort level and laminating degree with the cladding of part opening 101, stretch out the opening 101 part of inner tube 1 and can reduce the extrusion that causes opening 101 when the cushion 5 extrudees, avoid leading the undergauge (being not smooth) of sound passageway 10.

Furthermore, the elastic pad 5 is composed of two blocks, including a first block 51 and a second block 52, the diameter of the first block 51 is smaller than that of the second block 52, and the diameters of the first block 51 and the second block 52 are provided with arc-shaped transition concave parts 53. First, the first block 51 can be pressed against the auditory canal 3 and the sound-guiding channel 10 can be completely inserted, so that external interference is reduced, the sound-guiding channel can be inserted into a deeper position of the auditory canal 3, and the pressing feeling is reduced.

In the embodiment of the present invention, the outer wall of the inner tube is further covered with a rigid support sleeve 7. The elastic cushion is used for preventing the elastic cushion 5 from excessively deforming to cause the diameter reduction of the inner pipe, and the arrangement of the inner pipe can be set according to the actual situation.

Specifically, the open 101 end of the inner tube is made of a rigid material. Wherein a plastic with a higher hardness may be used or a corresponding bracket may be coated, thereby reducing the deformation of the opening 101. Wherein the elastic pad 5 is made of a memory foam material, such as polyurethane.

More specifically, the inner tube 1 and the elastic pad 5 are formed separately. Specifically, the inner tube 1 is formed first, and then the elastic pad 5 is formed by extrusion molding or a die.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
