In this application, the earphone 100 is a rear-mounted earphone. The earphone 100 includes a speaker assembly 10, a functional assembly 20, an ear hook 30, and a rear hook 40, where the speaker assembly 10 is used to attach to the head of a human body and transmit sound, and is electrically connected to the speaker assembly 10, the ear hook 30 is rigidly connected between the speaker assembly 10 and the functional assembly 20, and the number of the speaker assembly 10, the functional assembly 20, and the ear hook 30 can be two, which correspond to the left and right sides of the head of the human body. It is understood that in other embodiments of the present application, the headset 100 may be a headset or a variety of types of headphones, such as an ear-hook headset, and may not have a back-hook 40 or an ear-hook 30. The functional component 20 may be integrated with the speaker assembly 10, i.e. the functional component 20 and the speaker assembly 10 are of a non-independent structure and may be integrated together.

In this embodiment, the speaker assembly 10 is a sound emitting assembly of the earphone 100, and converts an input audio electric signal into mechanical vibration, and transmits the vibration to the eardrum of the user through the head bone, thereby allowing the user to hear the sound of the earphone 100. In other words, the sound transmission mode of the speaker assembly 10 in the present embodiment is bone conduction. It will be appreciated that in other embodiments of the present application, the sound transmission of the speaker assembly 10 may be by air conduction or a combination of bone and air conduction.

The functional component 20 may comprise a battery housing, a circuit board and/or a battery, the battery housing being adapted to receive the circuit board and/or the battery, one end of the ear-hook 30 being connected to the battery housing and the other end of the ear-hook 30 being connected to the speaker assembly 10.

When the earphone 100 is worn, the ear hook 30 is hung over the auricle 200, and the rear hook 40 is connected between the two sets of functional components 20 or between the two ear hooks 30. In some embodiments of the present application, the earhook 30 may be inverted "U" shaped. In some other embodiments, the ear hook 30 may be in other forms, and is not specifically limited herein.

As shown in fig. 1, in the earphone 100 provided in the present application, the speaker assembly 10 and the functional assembly 20 exist independently, and the speaker assembly 10 is located at the front side of the auricle 200.

In other embodiments, the speaker assembly 10 may be located on or posterior to the pinna, in contact with the pinna 200, or in contact with the user's head. The wearing position of the speaker assembly 10 when the earphone 100 is worn is not particularly limited in this application.

As shown in fig. 2, the earphone 100 includes a shutter 50, the shutter 50 being disposed on the speaker assembly 10. The shutter 50 comprises a first shutter 52, the first shutter 52 being connected to the loudspeaker assembly 10. Wherein, in the worn state, the first blocking member 52 extends from the speaker assembly 10 to the ear canal 300. In the present embodiment, the direction from the speaker unit 10 to the ear canal 300 is the positive a-axis direction, that is, in the present embodiment, the first baffle 52 is formed to extend from the speaker unit 10 in the positive a-axis direction.

The speaker assembly 10 includes a housing 12 and a speaker, the speaker being a sound emitting body of the speaker assembly, the housing 12 being for housing the speaker.

With continued reference to fig. 3, fig. 3 is a schematic view of the speaker assembly and the shield in the earphone of fig. 2.

Specifically, the housing 12 is provided with a sound outlet face 121, and a first side 122, a second side 123, and a third side 124 adjacent to the sound outlet face 121, and the shield 50 may be coupled to the first side 122, the second side 123, and the third side 124, and in some embodiments, the first baffle 52 may be coupled to the first side 122.

Preferably, the first baffle 52 may also be connected to the sound outlet surface 121 or the top surface 125 of the speaker assembly 10. The sound output surface 121 faces the head, is the surface of the speaker assembly 10 close to the user, and the top surface 125 is the surface of the speaker assembly 10 away from the user. When the first baffle 52 is connected with the sound outlet surface 121, vibration between the first baffle 52 and the loudspeaker assembly 10 can be kept consistent, so that effects of increasing sound volume and improving sound quality are achieved.

The shield 50 is connected to the speaker assembly 10 and extends in a direction from the speaker assembly 10 to the ear canal 300, and sound waves generated by vibration of the speaker assembly 10 can be reflected more toward the ear canal 300 through the shield 50, thereby enabling an increase in sound of the earphone 100 heard by the user. In addition, when the loudspeaker assembly 10 vibrates, the shielding piece 50 can also be driven to vibrate, and the shielding piece 50 can drive ambient air to vibrate to generate air conduction sound and transmit the air conduction sound to the auditory canal 300 of the user, so that the volume heard by the user is enhanced. Since the earphone 100 of the present application can vibrate to produce a vibration sound in addition to the speaker assembly 10, the shield 50 can also produce an air guide sound, thereby enabling the user to hear a greater volume than a purely bone-guided vibration earphone. At this time, the vibration intensity of the speaker assembly 10 of the earphone 100 of the present application may be lower than that of a simple bone conduction vibration earphone, so as to obtain the required volume, and further reduce the leakage sound generated by the speaker assembly 10. Further, the shielding member 50 in some embodiments of the present application may also shield part of the ear canal 300 from external noise, so as to reduce the influence of external noise on the listening effect, increase the volume of the earphone 100, and reduce the leakage of the earphone 100.

In some embodiments of the present application, the shield 50 may be the same material as the housing 12 of the loudspeaker assembly 10, and may be integrally formed with the housing 12 of the loudspeaker assembly 10. It will be appreciated that the shield 50 may be made of other materials, and may be fixedly connected to the speaker assembly 10 by various fixing means, such as clamping, welding, or screwing.

In some embodiments, the material of the shield 50 may be a wind noise resistant material. The wind noise prevention material is mainly in a loose porous structure, such as foam or porous silica gel, and the like, and the porosity of the wind noise prevention material is generally 10% -80%, and the loose porous structure can reduce the air speed near the surface of the wind noise prevention material, so that wind noise is reduced, and the influence of excessive wind noise on the listening of users is avoided; the wind noise prevention material can also be a loose plush structure, and the structure can also reduce the air speed near the surface of the wind noise prevention material and reduce wind noise.

In the present embodiment, in the wearing state, the first side 122 faces the direction of the ear canal 300, the first blocking member 52 is connected to the first side 122, and the first blocking member 52 is designed in a square flat plate shape. The flat design ensures that the first baffle 52 achieves shielding effect and simultaneously ensures the light weight of the loudspeaker assembly 10, so as to avoid discomfort of wearing of a user caused by the weight increase of the loudspeaker assembly 10 due to overlarge volume. Alternatively, the first stopper 52 may also be in the shape of an arc plate or a curved plate.

In other embodiments, the cross-section of the speaker assembly 10 along the direction of sound vibration may be circular, oval, or racetrack, which are not specifically limited herein.

Specifically, the first baffle 52 extends towards the direction from the speaker assembly 10 to the ear canal 300, and when the first baffle 52 follows the speaker assembly 10 to vibrate, surrounding air is driven to vibrate to generate air conduction sound, and at this time, the air conduction sound can be more conducted into the concha cavity of the user, so that the user can hear more volume. At this time, the vibration intensity of the speaker assembly 10 of the earphone 100 of the present application may have a lower vibration intensity, so as to obtain a desired volume, and further reduce the leakage sound generated by the speaker assembly 10. Further, the first blocking member 52 extends toward the speaker assembly 10 to the ear canal 300 to partially block the ear canal 300 to isolate external noise, so as to reduce the influence of external noise on the listening effect, increase the volume of the earphone 100, and reduce the leakage of the earphone 100.

In the present embodiment, the thickness of the first stopper 52 may be uniform, that is, the thickness of each position of the first stopper 52 is the same.

With continued reference to fig. 4, fig. 4 is a schematic bottom view of an embodiment of an earphone provided in the present application.

It will be appreciated that in other embodiments of the present application, the thickness of the first stop 52 may vary from location to location. For example, in some embodiments of the present application, the thickness of the first stopper 52 gradually decreases from the direction approaching the speaker assembly 10 to the direction away from the speaker assembly 10, and the connection between the first stopper 52 and the connection position of the housing 12 is smooth, avoiding stress concentration at the connection position.

With continued reference to fig. 5, fig. 5 is a schematic plan view of the speaker assembly and the shield of the earphone of fig. 2.

In some embodiments of the present application, the first dimension a of the first baffle 52 in the first direction a is less than or equal to twice the second dimension b of the loudspeaker assembly 10 in the first direction a. The first direction a is an extending direction from the speaker assembly 10 to the ear canal 300, and the first dimension a is a distance between an end of the first baffle 52 away from the speaker assembly 10 and the first side. For example, the first dimension a is equal in size to 0.5 times the second dimension b; the first dimension a is equal in size to the second dimension b; or the first dimension a is equal in size to 1.5 times the second dimension b; or the first dimension a is 2 times as large as the second dimension b, the application is not specifically limited herein.

The first dimension a is less than or equal to twice the second dimension b and the size is not zero, so that sound waves vibrated by the loudspeaker assembly 10 can be reflected to the ear canal 300 through the shielding piece 50 more, and the volume of the earphone 100 heard by a user is increased; in addition, the first blocking piece 52 can be ensured not to extend to the ears of the user too much, and the weight of the first blocking piece 52 can be reasonably controlled, so that the discomfort of wearing the user caused by too long or too heavy first blocking piece 52 is avoided. In addition, the first baffle 52 can vibrate along with the speaker assembly 10 to drive the ambient air to vibrate to generate air conduction sound to be transmitted to the ear canal 300 of the user, so that the user can hear the sound volume larger than that of the simple bone conduction vibration earphone, and the leakage sound of the earphone 100 can be reduced.

In some embodiments, when the user wears the earphone 100, the projection of the first baffle 52 on the ear of the user is at least partially located in the concha cavity, so that the air-guide sound generated by the vibration of the baffle 50 can enter into the ear canal 300 more and be heard by the ear, and the sound wave vibrated by the loudspeaker assembly 10 can be reflected to the ear canal 300 more through the baffle 50, so that the volume of the earphone 100 heard by the user is increased. Further, in the wearing state, the first blocking member 52 covers the concha cavity of the user, and this arrangement ensures that the first blocking member 52 covers a larger area of the concha cavity than in the above-described embodiment, so that the air-induced sound generated by the vibration of the blocking member 50 enters the ear canal 300 to the greatest extent, and the volume of the earphone 100 heard by the user is increased.

In some embodiments, the shield 50 further includes a second stop 54, the second stop 54 being coupled to the second side 123 and/or the third side 124, a third dimension c of the second stop 54 in a second direction B being less than or equal to the first dimension a, the second direction B being perpendicular to the first direction a.

In this embodiment, the second blocking member 54 is a flat plate and has two blocks, which are respectively disposed on the second side 123 and the third side 124, and the first blocking member 52 and the second blocking member 54 are spliced together to form a square flat plate for shielding the ear canal 300, so that the shielding area of the shielding member 50 for shielding the ear canal 300 can be increased. In the present application, the first stopper 52 and the second stopper 54 may be flat plates having various shapes such as square shapes and circular arcs, or the first stopper 52 and the second stopper 54 may be arc-shaped plates or curved plates, and the shapes and the like of the first stopper 52 and the second stopper 54 are not particularly limited in the present application. The first blocking member 52 and the second blocking member 54 may be independent structures, and the first blocking member 52 and the second blocking member 54 may be integrally formed structures.

In some embodiments, the thickness of the second baffle 54 may vary at different locations, for example, the thickness of the second baffle 54 may gradually decrease from the direction closer to the speaker assembly 10 to the direction away from the speaker assembly 10, and the connection between the second baffle 54 and the connection location of the housing 12 of the speaker assembly 10 is smooth, so as to avoid stress concentration at the connection location of the second baffle 54 and the housing 12 of the speaker assembly 10.

With continued reference to fig. 6-8, fig. 6 is a schematic diagram of the sound pressure in the ear canal in the two states of the earphone without and with the baffle as shown in fig. 2, fig. 7 is a schematic diagram of the size of the earphone shield as shown in fig. 2 in relation to the external sound heard, and fig. 8 is a schematic diagram of the sound heard by the earphone as shown in fig. 2 in relation to the first and third sizes of the shield.

As shown in fig. 6, the sound pressure in the ear canal of the earphone 100 is significantly weak in the state where the shield 50 is not present, and the sound pressure in the ear canal 300 of the earphone 100 is significantly strong in the state where the shield 50 is present, whereby it can be seen that the shield 50 has a significant effect of raising the volume to which the earphone 100 is heard.

As shown in fig. 7 and 8, as the first size a of the first stopper 52 increases, the volume of the earphone 100 is heard to become gradually large. When the first dimension a is smaller, the increase of the third dimension c of the second baffle 54 has little influence on the volume of the hearing headphone 100, wherein the third dimension c is the distance between the second side 123 and the end of the second baffle 54 connected to the second side 123, which is far away from the speaker assembly 10, or the distance between the third side 124 and the end of the second baffle 54 connected to the third side 124, which is far away from the speaker assembly 10; when the first size a is larger, the increase of the first size a has little influence on the volume of the hearing aid 100. In other words, in the present application, the first blocking member 52 plays a dominant role in shielding external noise, and the more the first blocking member 52 shields the area of the ear canal, the better the effect, but when the area of the first blocking member 52 shields the ear canal 300 reaches a certain value, the gain effect of increasing the first size a is weakened.

In this embodiment, the first baffle member 52 and the second baffle member 54 are both flat plates, and the first baffle member 52 is relatively perpendicular to the first side surface 122, and the second baffle member 54 is perpendicular to the second side surface 123 and the third side surface 124, so that a stronger sound insulation effect can be achieved with a smaller material volume.

In other embodiments, the first blocking member 52 may be disposed obliquely with respect to the first side 122, the second blocking member 54 may be disposed obliquely with respect to the second side 123 and/or the third side 124, for example, the angle between the first blocking member 52 and the sound emitting surface 121 or the top surface 125, and the angle between the second blocking member 54 and the sound emitting surface 121 or the top surface 125 may be ±60°, ±45°, or ±30°, so as to avoid discomfort of wearing caused by the shielding member 50 abutting against the auricle 200 when wearing the earphone 100.

In this application, the shield 50 may be fixedly connected to the housing 12 or movably connected to the housing 12. When the shield 50 is movably coupled to the housing 12, the shield 50 can be telescoped, rotated or folded relative to the housing 12 to change the area of the portion of the shield 50 exposed to the environment to accommodate different use scenarios. For example, when the outside noise is loud, the area of the portion of the shutter 50 exposed to the outside environment may be increased to increase the volume heard by the user; the area of the portion of the shield 50 exposed to the outside environment can be reduced when the outside noise is less, or when it is desired to hear the outside sound more clearly.

In some embodiments, the earphone 100 further includes a driving member 14, a sensor and a controller, wherein the driving member 14 and the sensor are electrically connected with the controller, the sensor is a sound sensor for detecting environmental noise and transmitting an electrical signal to the controller, the controller is a PCB board or a circuit board with a control circuit for adjusting the extension length of the first blocking member 52 or the second blocking member 54 relative to the casing 110 based on the detected environmental noise, and the driving member 14 is connected with the first blocking member 52 or the second blocking member 54 for driving the first blocking member 52 or the second blocking member 54 to stretch, rotate or fold so as to change the extension length. The sensor senses that the ambient noise is relatively large, and can control the driving member 14 to drive the first blocking member 52 or the second blocking member 54 to extend more than the first blocking member 52 or the second blocking member 54, and the sensor senses that the ambient noise is relatively small, and can control the driving member 14 to drive the first blocking member 52 or the second blocking member 54 to extend less than the first blocking member 52 or the second blocking member 54. The first blocking member 52 is driven to extend or retract into the housing 12 by the driving member 14.

In other embodiments, the earphone 100 may not include a sensor or controller, and the user may manually adjust the shield 50 based on his/her own sensed signal to adjust the shield 50 to the proper extent for extension from the housing 12.

With continued reference to fig. 9, fig. 9 is a schematic view of a first embodiment of the enclosure and shutter of the speaker assembly.

In the embodiment shown in fig. 9, the driving member 14 includes a screw 140 and a nut 141, the nut 141 is threaded on the screw 140, the screw 140 has threads, and the pattern on the inner side of the nut 141 matches the threads. When the screw 140 rotates, the nut 141 can move in the axial direction of the screw 140. The first stopper 52 is connected with the nut 141.

In this embodiment, as shown in fig. 9, the first stopper 52 is partially located in the housing 12, and the screw 140 and the nut 141 are both disposed in the housing 12. The nut 141 is connected to the end of the first blocking member 52, the screw rod 140 is parallel to the first blocking member 52, and when the nut 141 moves on the screw rod 140, the first blocking member 52 can be driven to extend and retract into and out of the housing 12 along the direction parallel to the screw rod 140, so that the extending length of the first blocking member 52 relative to the housing 12 can be adjusted, and the area of the first blocking member 52 for shielding the auditory canal 300 can be changed according to the use environment.

In other embodiments, the screw 140 may be disposed obliquely with respect to the first blocking member 52, and the angle formed by the screw 140 and the first blocking member 52 may be 15 °, 30 ° or 45 °, which is not limited in this application.

With continued reference to fig. 10, fig. 10 is a schematic view of a second embodiment of the enclosure and shutter of the speaker assembly.
