When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.
It should be noted that the terms of orientation such as left, right, up and down in the embodiments of the present invention are only relative to each other or are referred to the normal use state of the product, and should not be considered as limiting.
The invention provides an in-ear earphone capable of adjusting the length of a front cavity of a loudspeaker, which is mainly used for an in-ear Bluetooth earphone or other in-ear earphones. The front sound cavity of the earphone mainly affects the middle-high frequency part of the earphone, a high-frequency wave peak can continuously move to the left along with the increase of the volume of the front sound cavity, a high-frequency resonance point can be lower and lower, and the logarithmic value of the change of the high-frequency resonance point and the increment of the volume of the front sound cavity almost form a linear relation.
Please refer to fig. 1 and fig. 2, which includes: earphone body 10 and in-ear earcap 20, the front end of earphone body 10 is provided with loudspeaker installation cavity 102, be provided with loudspeaker 101 in the loudspeaker installation cavity 102, the front side that the front end of loudspeaker installation cavity 102 is located loudspeaker 101 is loudspeaker front cavity 103, in-ear earcap 20 mobilizable set up in loudspeaker front cavity 103. The front sound cavity of the loudspeaker of the earphone is a cavity between the sound outlet side of the loudspeaker and the outer end of the sound outlet hole of the earphone, and the length of the front sound cavity of the loudspeaker is adjusted by adjusting the position of the in-ear type ear cap 20 in the front sound cavity 103 of the loudspeaker, so that the middle and high frequency range effect of sound effect expression of the loudspeaker can be adjusted according to the requirements of users, and different sound quality requirements of different music are met.
With reference to fig. 1 and fig. 2, the in-ear earcap 20 includes a hard mounting portion 202 and a soft earcap 203, through holes 201 for transmitting sound are disposed on both the hard mounting portion 202 and the soft earcap 203, the sound emitted from the speaker 101 is transmitted to ears of a human body through the through holes 201, and the distance from the speaker to the outer end of the through holes 201 is controlled to adjust the length of a front sound cavity of the speaker, so as to adjust the high-frequency tone quality of the earphone.
With reference to fig. 1 and fig. 2, the middle portion of the soft earcap 203 gradually becomes thinner from the front end to the middle portion, and the soft earcap 203 is folded outward to fit the external auditory canal of the human body. In this embodiment, the soft ear cap 203 is a soft silica gel ear cap or a soft TPU (Thermoplastic polyurethane elastomer rubber) ear cap, the wall thickness of the vertical part of the soft ear cap 203 can be smaller than or equal to that of the front cavity section of the earphone, when the earphone is worn in the ear, the vertical part is sealed by the extrusion between the soft ear cap 203 and the external auditory canal, the through hole 201 is prevented from being sealed by the extrusion between the soft ear cap and the external auditory canal, the folded part of the soft ear cap 203 is matched with the external auditory canal of the human body, and the wearing comfort of the earphone is improved.
The hard mounting portion 202 and the soft earcap 203 are integrally formed, so that the hard mounting portion 202 and the soft earcap 203 are reliably connected. Of course, the hard mounting portion 202 and the soft ear cap 203 may also be mounted in other ways (such as tight fitting, ring reverse, point reverse, segment reverse, etc.), and the inner wall of the mounting groove of the horn mounting cavity 102 may be provided with a ring-type, point-type or segment-type concave-convex structure to adapt to the hard mounting portion 202 for adjustment, which is not limited by the present invention.
Referring to fig. 1 and fig. 2, the root of the soft ear cap 203 is in interference fit with the inner wall of the horn front cavity 103, so that the in-ear cap 20 can be moved and positioned at any position in the horn front cavity 103 by the interference fit, and the adjustment manner is simple.
The inner wall of loudspeaker antechamber 103 is provided with the internal thread, the root of soft earcap 203 or stereoplasm installation department 202 be provided with interior screw-thread fit's external screw thread, the accessible revolves the mode soon and makes pleasant formula earcap 20 can remove in loudspeaker antechamber 103 optional position, and the difficult removal in back of position adjustment has moreover improved the reliability when adjusting, and its regulative mode is simple and convenient.
The inner wall of the horn front cavity 103 is provided with a plurality of clamping grooves, and the root of the soft ear cap 203 or the hard mounting part 202 is provided with a bulge matched with the clamping grooves. Because the hard mounting part 202 has a little deflection, the hard mounting part 202 is not easy to move after being well adjusted in a mode of matching with the clamping groove, and the reliability during adjustment is improved.
For better understanding of the present invention, the adjustment of the in-ear cap 20 will be described below with reference to fig. 3, in which the root of the soft ear cap 203 is in interference fit with the inner wall of the horn front cavity 103:
as shown in fig. 3, the initial mode of the in-ear earphone is the position shown in (1) in fig. 3, at this time, the total length of the speaker sound cavity is a, when the user needs to adjust the length of the front sound cavity of the speaker, the in-ear cap 20 can be pulled out for a section to the position shown in (2) in fig. 3, at this time, the total length of the speaker sound cavity is B, through comparison of (1) and (2), it can be known that B is longer than a, if the sound quality effect of the length of B cannot meet the user's requirement, the in-ear cap 20 can be pulled out continuously to the position shown in (3) in fig. 3, through comparison of the three graphs in fig. 3, C is longer than B and is longer than a, when the length of the speaker sound cavity needs to be shortened, the in-ear cap 20 can be pressed to move toward the speaker 101 side, so as to shorten the length of the speaker sound cavity, thereby achieving automatic adjustment according to the user's requirement.
In summary, the adjustable speaker mounting cavity is arranged, so that a part of the cavity is used as the front speaker cavity, and the in-ear earcap can freely move in the front speaker cavity to adjust the length of the front speaker cavity, thereby adjusting the length of the front speaker cavity according to the requirements of users and meeting the requirements of different music qualities of different music. The invention has simple operation mode, can completely adjust the length of the sound cavity in real time according to the needs of users, and has good operability.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
