In some embodiments, as shown in fig. 1 to 3, the earphone sound generating part 110 includes a body 111, the body 111 having a receiving cavity 112, the receiving cavity 112 having a vibration diaphragm 113 therein, the vibration diaphragm 113 dividing the receiving cavity 112 into a first sub-receiving cavity 1121 and a second sub-receiving cavity 1122; the first sub-housing chamber 1121 has a sound emission passage 114 communicating with the outside, and the second sub-housing chamber 1122 has a pressure release passage 115 communicating with the outside.

In particular, the earphone 100 is primarily sound quality, comfort and durability for use by a user. The sound quality of the earphone 100 is different from that of a sound box, sound waves emitted by the sound box are attenuated and interfered in the air, and interact with the head and ears of a person, and the sound of the earphone 100 directly enters the ears 200. Whether the sound emitted from the pressure release channel 115 interferes with the sound emitted from the sound emitting channel 114 directly affects the quality of the sound quality, so that in order to facilitate the explanation of the connection relationship between the earphone 100 and each part of the ear 200 of the user, the influence of the contact between each part of the earphone 100 and each part of the ear 200 on the sound quality, comfort and durability will be described in detail below by way of specific embodiments, and in the following, each part of the ear 200 will be described first, and as shown in fig. 4, the ear 200 includes an earlobe 210, an ear canal 220, a tragus 230, an concha 240, an antitragus 250, and so on. Meanwhile, for convenience in explaining the direction of the earphone 100, as shown in fig. 2 and 3, by establishing a coordinate system to assist understanding of the structural positional relationship of the earphone 100 in a three-dimensional space, the three-dimensional space has X, Y, Z three directions, and also has XY, XZ, YZ three planes, so that corresponding description will be made hereinafter, the length direction of the earphone sound emitting portion 110 is the X direction, the width direction of the earphone sound emitting portion 110 is the Y direction, and the thickness direction of the earphone sound emitting portion 110 is the Z direction. The plane of the longitudinal center plane 140 is an XY plane, the plane of the transverse center plane 150 is an XZ plane, and the plane of the radial center plane is a YZ plane.

The earphone sound generating part 110 is a part capable of generating sound, the earphone sound generating part 110 comprises a body 111, the body 111 is provided with a containing cavity 112, a sound generating device is arranged in the containing cavity 112, the sound generating device comprises a magnet, a coil, a vibrating diaphragm 113 and other parts, and sound is generated through the change of the vibrating diaphragm 113. In order to avoid the interference of the gases inside the accommodating chamber 112, the vibrating diaphragm 113 partitions the accommodating chamber 112 into a first sub-accommodating chamber 1121 and a second sub-accommodating chamber 1122, and the earphone sound generating part 110 has a sound generating channel 114 and a pressure releasing channel 115 on the surface thereof. The sound-producing channel 114 communicates the first sub-receiving cavity 1121 with the outside, the sound-producing channel 114 is composed of a plurality of small holes, the number and the size of the small holes are not limited, the sound produced by the vibrating diaphragm 113 can be emitted through each small hole of the sound-producing channel 114 according to the actual requirement, so that the sound is transmitted into the ear of the user, the specific setting position of the sound-producing channel 114 is not limited, and the sound-producing channel 114 can be positioned at the end of the earphone sound-producing part 110 according to the actual requirement, for example; it should be noted that, because various components in the earphone sound generating portion 110 exist, a certain thickness of the earphone sound generating portion 110 is caused, the specific shape of the earphone sound generating portion 110 is not limited, and any structure capable of accommodating the sound generating device is satisfactory, for example, the earphone sound generating portion 110 may be a cuboid structure. To further enhance the wearing comfort, the earphone sound emitting portion 110 may have an ellipsoidal structure. The surface of the earphone sound generating portion 110 is further provided with a pressure release channel 115, the pressure release channel 115 communicates the second sub-receiving cavity 1122 with the outside, and a specific shape thereof is not limited, for example, the pressure release channel 115 is a circular channel, for example, the pressure release channel 115 is in a shape of an arc slot. The pressure release channel 115 can also be formed by a plurality of small holes, the number of the small holes and the size of the small holes are not limited, the pressure generated by vibration of the vibration diaphragm 113 can be determined according to practical requirements, and can be discharged through the second sub-containing cavity 1122 and the pressure release channel 115, so that the pressure in the containing cavity 112 is released, the pressure release channel 115 can enable air to freely flow in the containing cavity 112, internal pressure accumulation is prevented, interference to vibration of the vibration diaphragm 113 is avoided, and accordingly sound quality change is avoided, and the earphone sound generating part 110 can generate better sound quality and bass effect.

The pressure release channel 115 and the sound generation channel 114 are both located on the first side 116 of the longitudinal center plane 140 of the earphone sound generation portion 110, the intersection point of the central axis 1151 of the pressure release channel and the central axis 1141 of the sound generation channel is located on the second side 117 of the longitudinal center plane 140, and the longitudinal center plane 140 is a plane where the geometric center point taking the thickness direction of the earphone sound generation portion 110 as a normal line is located.

Specifically, considering that the pressure release channel 115 may also generate sound, in order to avoid interference caused by the sound generated by the pressure release channel 115 to the sound generated by the sound generation channel 114, a plane where a geometric center point of the thickness direction of the earphone sound generation portion 110 is taken as a longitudinal center plane 140, the longitudinal center plane 140 divides the earphone sound generation portion 110 into a first side 116 and a second side 117, the pressure release channel 115 and the sound generation channel 114 are both located at the first side 116 of the longitudinal center plane 140 of the earphone sound generation portion 110, a central axis 1151 of the pressure release channel 115, and a central axis 1141 of the sound generation channel 114. It should be noted that, the angle α1 between the central axis 1151 of the pressure relief channel and the central axis 1141 of the sounding channel is not limited, and may be determined according to practical requirements, the greater the angle α1, the greater the degree that the pressure relief channel 115 and the sounding channel 114 face away from each other, for example, the angle α1 between the central axis 1151 of the pressure relief channel and the central axis 1141 of the sounding channel is 60 degrees; the smaller the angle α1, the closer the pressure relief channel 115 is oriented in the same direction as the sounding channel 114, e.g., the 30 degrees included angle α1 between the central axis 1151 of the pressure relief channel and the central axis 1141 of the sounding channel. In order to ensure that the sound emitted by the pressure relief channel 115 does not interfere with the sound emitted by the sound emitting channel 114, an included angle α1 between the central axis 1151 of the pressure relief channel and the central axis 1141 of the sound emitting channel is, illustratively, 30 degrees or more.

In some embodiments, as shown in connection with fig. 2 and 5, the first side 116 is the side that contacts the user's skin in the worn state, and the pressure relief channel 115 is sloped toward the user's skin. Specifically, under the condition that the pressure release channel 115 and the sounding channel 114 face different directions, further consider the situation that the earphone sounding portion 110 is matched with the ear 200 of the user, in the wearing state of the user, the sounding channel 114 faces the concha cavity 240, so that under the wrapping of the ear 200, the sounding channel 114 is not interfered by airflow, the pressure release channel 115 is directly communicated with the outside and is not in the surrounding range of the ear 200, therefore, the air flow may affect the pressure release of the pressure release channel 115, so that the sound quality may be reduced, in order to avoid the air flow influence as far as possible, the side contacting with the skin of the user is the first side 116, the pressure release channel 115 is made to be close to the skin of the user as far as possible, the pressure release channel 115 is inclined towards the skin side of the user, and the air flow rate closer to the skin surface is smaller, so that the air flow affects the pressure release of the pressure release channel 115 is reduced to a certain extent.

In some embodiments, as shown in fig. 6, the pressure relief channel 115 is located on a third side 118 of the lateral center plane 150 of the earphone sound generating portion 110, where the lateral center plane 150 is a plane in which a center point with the width direction of the earphone sound generating portion 110 as a normal line is located, and the third side 118 is a side close to the user's earlobe 210 in the wearing state. Specifically, the plane where the transverse center plane 150 is located is an XZ plane, where the pressure release channel 115 is located on the first side 116 of the longitudinal center plane 140 of the earphone sound generating portion 110, and in the wearing state of the earphone 100, the pressure release channel 115 is located on a side, closer to the ear 200, of the earphone sound generating portion 110, so that the influence of air flow on the pressure release channel 115 in pressure release can be reduced, the user experience is improved, in order to further improve the sound quality, the pressure release channel 115 is located on the third side 118 of the transverse center plane 150 of the earphone sound generating portion 110, and in the wearing state of the earphone 100, the third side 118 is a side, close to the earlobe 210 of the user. The pressure release channel 115 is closer to the tragus 230, the tragus 230 is utilized to block the air flow, the air flow around the pressure release channel 115 is further reduced, the influence of the air flow on the pressure release of the pressure release channel 115 is further reduced, and the sound quality is improved.

In some embodiments, as shown in connection with fig. 4 and 7, the pressure relief channel 115 is located at an end of the earphone sound emitting portion 110 that is remote from the sound emitting channel 114. Specifically, under the condition that the pressure release channel 115 and the sounding channel 114 face different directions, in combination with the situation that the user actually wears, the sounding channel 114 faces the concha cavity 240, and considering that the concha cavity 240 has a containing space with a certain size, if the pressure release channel 115 also faces the concha cavity 240, the sound generated by the pressure release channel 115 will also affect the sound generated by the sounding channel 114 due to the internal reflection of the concha cavity 240, so that the sound quality is reduced, and the pressure release channel 115 is located at one end of the earphone sounding portion 110 away from the sounding channel 114. Sound generated by the pressure release channel 115 can be effectively prevented from being reflected in the concha cavity 240, and the tone quality of the sound generation channel 114 in the earphone sound generation part 110 is ensured. The distance between the center of the sounding channel 114 and the center of the pressure release channel 115 is not limited, and may be determined according to practical requirements, where the center of the sounding channel 114 is the geometric center point of the sounding channel 114, and the center of the pressure release channel 115 is also the geometric center point of the pressure release channel 115. Too close a distance between the center of the sounding channel 114 and the center of the pressure relief channel 115 may cause sound generated by the pressure relief channel 115 to directly enter the concha cavity 240, thereby causing interference to sound generated by the sounding channel 114, too far a distance between the center of the sounding channel 114 and the center of the pressure relief channel 115 may cause the pressure relief channel 115 to be far away from the tragus 230, and the tragus 230 cannot be utilized to reduce air flow, so that air flow causes interference to pressure relief channel 115. For example, the distance between the center of the sound producing channel 114 and the center of the pressure releasing channel 115 is between 18 mm and 23 mm, so that the pressure releasing channel 115 is close to one side of the tragus 230, and the sound generated by the pressure releasing channel 115 can be prevented from being directly transmitted into the concha cavity 240, and the influence of air flow on the pressure discharging of the pressure releasing channel 115 can be reduced.

In some embodiments, as shown in fig. 7, the earphone sound generating portion 110 is provided with a sound generating boss 119, and the sound generating channel 114 is located on the sound generating boss 119. Specifically, in order to further improve the effect of receiving sound by the user and reduce the leakage of sound, the sounding boss 119 can be arranged at one end of the earphone sounding part 110 in the length direction, which can be simply understood as that the sounding boss 119 is arranged at one end of the earphone sounding part 110 towards the inner side of the concha cavity 240, the sounding channel 114 is arranged on the sounding boss 119, the sounding channel 114 can be further close to the auditory canal 220, the distance between the sounding channel 114 and the auditory canal 220 is shortened, the sound can be transmitted into the auditory canal 220 in a shorter time after the sounding channel 114 sounds, the stay time of the sound in the concha cavity 240 is reduced, and the leakage of the sound is reduced as much as possible. The structure and size of the sounding boss 119 are not limited, and may be determined according to practical requirements, for example, the sounding boss 119 is a cylinder, and the sounding channel 114 is located on the top surface of the cylinder.

In some embodiments, as shown in connection with fig. 5 and 7, the top surface of the sound emitting boss 119 is angled from the vertical plane when the headset 100 is in a worn state such that the top surface is facing the ear canal 220. Specifically, in order to make a finer improvement on the earphone 100, considering that the ear canal 220 of the ear 200 is hidden behind the tragus 230, the sounding boss 119 extends toward the inner side of the concha cavity 240, the top surface of the sounding boss 119 does not directly face the ear canal 220, and in order to further shorten the distance between the sounding channel 114 and the ear canal 220, the top surface of the sounding boss 119 is inclined, so that an included angle exists between the top surface of the sounding boss 119 and a vertical plane, and the top surface of the sounding boss 119 can face the ear canal 220. After the sound channel 114 generates sound, the sound directly enters the ear canal 220 along a straight line, and the value of the included angle between the top surface of the sound producing boss 119 and the vertical plane is not limited, and can be adaptively adjusted according to the type of the user wearing the sound producing boss 119, for example, the included angle between the top surface of the sound producing boss 119 and the vertical plane is 20 degrees.

In some embodiments, when the earphone 100 is further refined and improved, the sounding boss 119 can effectively transmit sound, shorten the transmission distance, and reduce the leakage of sound, and considering the internal structure of the ear 200, the sounding boss 119 may interfere with the auricle 250 or other parts, so as to squeeze the auricle 250 or other parts, thereby reducing the experience of the user and affecting the wearing comfort. To improve this, the sounding boss 119 gradually narrows away from the earphone sounding portion 110, which can be simply understood as that when the sounding boss 119 extends toward the concha chamber 240, the cross-sectional area of the extending end of the sounding boss 119 gradually decreases, so that interference between the sounding boss 119 and the auricular foot 250 or other parts is avoided. With respect to the components of the earphone 100 only contacting the ear 200, in the absence of force, the earphone 100 will not have an uncomfortable effect on the ear 200, and the side or top surface of the sounding boss 119 will not engage the concha cavity 240 and will not affect the comfort of wear. Thus, as the sound emitting boss 119 is gradually narrowed as it extends toward the concha chamber 240, the sound emitting boss 119 may at least partially conform to the concha chamber 240.

One end of the earphone connection part 120 is connected to the earphone sound emitting part 110, and the earphone connection part 120 extends in a curved direction, which is understood as a curved structure, that is, the earphone connection part 120 bypasses the upper side of the ear 200 from the front side of the ear 200 and extends to the rear side of the ear 200 along the auricle, so that the earphone connection part 120 is attached to the upper side and the rear side of the ear 200, and the earphone 100 can be well fixed to the ear 200. The other end of the earphone connection part 120 is connected with the earphone battery part 130, and a specific connection mode is not limited, for example, one end of the earphone battery part 130 is provided with an installation channel, a clamping interface is arranged in the installation channel, and the other end of the earphone connection part 120 is connected with one end of the earphone battery part 130 in a clamping manner; for example, the earphone connecting portion 120 is connected by an interference fit, the diameter of the other end of the earphone connecting portion 120 is slightly larger than the size of the mounting channel, and the other end of the earphone connecting portion 120 is fixed in the mounting channel by the interference fit. For example, a screw-fitting connection method may be adopted, in which a screw hole is provided in the mounting channel, a screw head is provided at the other end of the earphone connection portion 120, and the connection is made to one end of the earphone battery portion 130 by means of screw connection.
