In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
Fig. 1 is a partially exploded view of a half-in-ear headphone according to one embodiment of the present invention. Fig. 2 is an assembly view of a half-in-ear headphone according to one embodiment of the present invention. Fig. 3 is an internal schematic view of a half-in-ear headphone according to one embodiment of the present invention.
As shown in fig. 1 to 3, the half-in-ear earphone includes: the earphone comprises an earphone body and a supporting part. The earphone body includes a housing 15. The housing 15 has an inner cavity. The speaker unit 16 is disposed in the inner cavity. The diaphragm of the speaker unit 16 divides the inner cavity into a front cavity 23 and a back cavity 24. Among these, near the magnetic circuit of the speaker unit 16 is the back chamber 24. Adjacent the vibrating system is a front chamber 23.
The housing 15 is provided with a first sound outlet hole 11 and a second sound outlet hole 12. The cross-sectional areas of the first sound outlet hole 11 and the second sound outlet hole 12 are different. The first sound outlet hole 11 communicates with the front chamber 23 of the housing 15. The second sound outlet hole 12 communicates with the rear chamber 24 of the housing 15. For example, the first sound outlet hole 11 and the second sound outlet hole 12 are disposed oppositely.
The support portion is configured for mating with an ear of a user to position the half-in-ear headphone. The support is detachably connected to the housing 15. The support is connected to the housing 15, for example, by means of a snap-fit, friction connection. A through hole 22 is provided on the support.
In the case where the first sound outlet hole 11 is used, the support portion covers the outside of the second sound outlet hole 12, and the through hole 22 communicates with the second sound outlet hole 12. The through hole 22 communicates with the external environment. In this case, the vibrating air flow of the speaker unit 16 is radiated through the first sound outlet hole 11. The second sound outlet 12 and the through hole 22 together play a role of pressure relief to balance the sound pressure before and after the diaphragm. Gas can pass through the through-holes 22, but sound cannot pass through the through-holes 22.
In the case where the second sound outlet hole 12 is used, the support portion covers the outside of the first sound outlet hole 11, and the through hole 22 communicates with the first sound outlet hole 11. In this case, the vibrating air flow of the speaker unit 16 is radiated through the second sound outlet hole 12. The first sound outlet 11 and the through hole 22 together play a role of pressure relief to balance the sound pressure before and after the diaphragm. Gas can pass through the through-holes 22, but sound cannot pass through the through-holes 22.
It should be noted that the magnetic conductive plate or the side wall of the speaker unit 16 has a rear exit hole. The rear outlet hole is communicated with the interior of the magnetic circuit system. The vibrating airflow formed at the rear of the diaphragm is radiated from the rear outlet hole to the rear chamber 24, and then radiated to the external environment through the second sound outlet hole 12 to generate sound.
In the embodiment of the present invention, the housing 15 includes the first sound outlet hole 11 communicating with the front chamber 23 and the second sound outlet hole 12 communicating with the rear chamber 24. When the first sound outlet hole 11 is used, the user covers the second sound outlet hole 12 through the support portion. Since the support portion is provided with the through hole 22 and the through hole 22 communicates with the second sound outlet hole 12, the sound pressure of the front and rear of the diaphragm can be balanced. When the second sound outlet hole 12 is used, the user covers the first sound outlet hole 11 through the support portion. Since the support portion is provided with the through hole 22 and the through hole 22 communicates with the first sound outlet hole 11, the sound pressure of the front and rear of the diaphragm can be balanced.
Because the sectional areas of the first sound outlet 11 and the second sound outlet 12 are different, the half-in-ear earphone can provide sound experience with different effects, and the user experience is improved.
In one example, as shown in fig. 1, the support portion includes a recessed portion 19. The recess 19 forms an open cavity. The through hole 22 communicates with the recess 19. A portion of the housing 15 for enclosing the first sound outlet hole 11 is inserted into the recess 19, or a portion of the housing 15 for enclosing the second sound outlet hole 12 is inserted into the recess 19. For example, a frictional force is formed between the housing 15 and the support portion. In this way, the housing 15 is fixed in the recess 19, which makes the connection of the support to the housing 15 more secure.
In one example, the support portion includes an arm 18. The arms 18 fit within grooves on the inside of the user's ears. For example, the arms 18 are shark-horn shaped. The arms 18 extend radially. Radial is the direction perpendicular or substantially perpendicular to the direction of extension of the ear canal when the earpiece is worn. When worn, the earphone body is close to the ear canal. The arms 18 nest within the pinna and fit within the channels on the inside of the ear. The outer contour of the arm 18 is ergonomically designed to match the configuration of the channel on the inside of the ear for enhanced comfort of wear. The arms 18 engage with the grooves on the inner side of the ear, which effectively prevents the headset from rotating, and thus the position of the headset is more fixed.
In addition, the support arm 18 fixes the relative position of the first sound outlet 11 or the second sound outlet 12 and the ear canal, thereby ensuring good listening effect.
In another example, the support portion includes an ear portion. The ear hanging part is hung outside the ear of the user. For example, a curved cantilever of the ear portion. When worn, the curved cantilever arms hang outside the ears (e.g., in the gap between the upper side of the ears and the head). The ear hanging part can effectively avoid the falling of the earphone.
In addition, the ear-hanging part is arranged so that the shell 15 does not need to be inserted into the ear canal, and pain caused by wearing the earphone on the inner side of the ear of the user for a long time is avoided.
Optionally, the support is made of silicone or rubber. The support portion is integrally formed by, for example, injection molding. The soft texture of these two materials makes it more comfortable to wear the half-in-ear headphone.
Optionally, at least one of the first sound outlet hole 11 and the second sound outlet hole 12 has a cross section in a circular shape, an oval shape, a kidney shape, or a regular polygon shape. The shape of the first sound outlet hole 11 and the second sound outlet hole 12 can be set by those skilled in the art according to actual needs.
In one example, the first sound outlet hole 11 includes a plurality. The sectional areas of the plurality of first sound outlet holes 11 are different, and in the case where one of the first sound outlet holes 11 is used, the other first sound outlet holes 11 are closed. In this example, the second sound outlet hole 12 is covered by the support portion when one of the first sound outlet holes 11 is used. The second sound outlet 12 communicates with the through hole 22 to adjust the sound pressure of the diaphragm in front and back. The other first sound outlet holes 11 are closed, for example by a support or by another sealing. Since the plurality of first sound outlet holes 11 have different sectional areas, the half-in-ear headphone can provide more sound effects. The user may select different first sound outlet apertures 11 according to different listening types.
In one example, the second sound outlet hole 12 includes a plurality. The sectional areas of the plurality of second sound outlet holes 12 are different, and in the case where one of the second sound outlet holes 12 is used, the other second sound outlet holes 12 are closed. In this example, the first sound outlet hole 11 is covered by the support portion when one of the second sound outlet holes 12 is used. The first sound outlet 11 is communicated with the through hole 22 to adjust the sound pressure of the front and back of the diaphragm. The other second sound outlet holes 12 are closed, for example, by a support or by another sealing member. Since the plurality of second sound outlet holes 12 have different sectional areas, the half-in-ear headphone can provide more sound effects. The user can select the second sound outlet 12 with different cross-sectional area according to different listening types.

The sound vent 17 is used for balancing the sound pressure of the front and the back of the diaphragm. The front chamber 23 and the rear chamber 24 are formed as described above. The sealing portion is configured to seal the other third sound outlet holes 13 in the case where one of the third sound outlet holes 13 is used. For example, the sealing portion is made of silicone, rubber, plastic, or metal. The sealing portion is inserted into or covers the third sound outlet hole 13 to seal the third sound outlet hole 13. For example, the sealing portion includes the above-described ear hanging portions or the above-described arms.
As shown in fig. 4, the third sound outlet holes 13 include two, and the two third sound outlet holes 13 are disposed oppositely. The speaker unit 16 is provided with a through hole 21.
