Referring to fig. 1 to fig. 2, fig. 1 is a schematic structural diagram of an earphone 10 according to an embodiment of the present application, and fig. 2 is an exploded structural diagram of the earphone 10 in fig. 1.

As shown in fig. 1 and 2, the earphone 10 used here may be a wireless earphone or a wired earphone. Here, the earphone 10 is described as a wireless earphone as follows. The earphone 10 can be used in cooperation with an electronic device such as a mobile phone, a tablet computer, a notebook computer, etc., to convert a received electrical signal into mechanical vibration, thereby realizing the sound production function of the earphone 10. The headset 10 may include: housing 100, stand 200, tweeter 300, woofer 400, battery 500, and circuit board 600. An accommodating space 101 is formed in the housing 100. The bracket 200, the tweeter 300, the woofer 400, the battery 500, and the circuit board 600 are disposed in the accommodating space 101. The bracket 200 is used for dividing the accommodating space 101. The tweeter 300 and the woofer 400 may be disposed at one side of the stand 200, and the sound emitted from the tweeter 300 and the woofer 400 can be conducted to the outside of the earphone 10 through the housing 100. The battery 500 and the circuit board 600 are disposed at the other opposite side of the bracket 200, and the tweeter 300, the woofer 400, and the battery 500 are electrically connected to the circuit board 600 to implement their respective functions. In this embodiment, the tone of the tweeter 300 may be blended with the tone of the woofer 400, so as to reduce the sense of separation of the tweeter 300 and the woofer 400 in tone, and improve the sound quality of the headphone 10.

As shown in fig. 2, the casing 100 can be used as a carrier of the functional components of the earphone 10, and the casing 100 can be matched with the shape of the ear of the human body in shape to improve the wearing comfort of the user. The housing 100 may include a front case 110 and a rear case 120. The front shell 110 may be connected to the rear shell 120, and the two shells together enclose the accommodating space 101. The front case 110 may be used to house the tweeter 300 and the woofer 400, and the rear case 120 may be used to house the battery 500 and the circuit board 600. In this embodiment, the front shell 110 and the rear shell 120 may be made of hard plastic, so that the front shell 110 and the rear shell 120 may have a certain structural strength. Meanwhile, since the front shell 110 and the rear shell 120 are generally directly exposed to the external environment, the front shell 110 and the rear shell 120 may also have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant is coated on the outer surfaces of the front shell 110 and the rear shell 120 (i.e., the outer surface of the earphone 10). Further, in some embodiments, the front housing 110 and the rear housing 120 may be designed with the same color to improve the appearance consistency of the headset 10. In other embodiments, the front shell 110 and the rear shell 120 may be designed with different colors to show different appearance effects. Meanwhile, corresponding brand marks (LOGO) can be arranged on the front shell 110 and the rear shell 120 to beautify the appearance of the earphone 10 and improve the brand recognition degree. All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture (as shown in the drawings), and if the certain posture is changed, the directional indication is changed accordingly.

Referring to fig. 3 to 4, fig. 3 is a schematic view showing an assembly structure of the front housing 110, the tweeter 300 and the woofer 400, and fig. 4 is a schematic view showing a sectional structure of the front housing 110, the tweeter 300 and the woofer 400 along xi-xi in fig. 3.

As shown in fig. 3, the front case 110 may be used to mount the tweeter 300 and the woofer 400, and the front case 110 may conduct sounds emitted from the tweeter 300 and the woofer 400 to perform a sound emitting function of the headset 10. The front case 110 may include a main body portion 111 and an extension portion 112 of a unitary structure. The extending portion 112 may be located on one side of the main body portion 111 and extend in a direction away from the main body portion 111. The main body 111 may be used to mount the tweeter 300 and the woofer 400, and the extension 112 may be used to transmit the sound emitted from the tweeter 300 and the woofer 400 to the outside of the headset 10.

As shown in fig. 4, the main body portion 111 may have a first receiving cavity 1011 configured to receive the tweeter 300 and the woofer 400, and the extension portion 112 may have a sound outlet hole 1121 configured to communicate the first receiving cavity 1011 and the outside of the front case 110. Thus, the tweeter 300 and the woofer 400 may be disposed in the first receiving cavity 1011, and the sound emitted from the tweeter 300 and the woofer 400 may be conducted to the outside of the earphone 10 through the sound emitting hole 1121. In the present embodiment, the volume of the first receiving cavity 1011 in the direction close to the sound outlet hole 1121 is gradually reduced, so that the inner wall of the first receiving cavity 1011 is designed in a shape of "eight" in the direction close to the sound outlet hole 1121, that is, the front shell 110 may have a shape similar to a funnel in appearance. Thus, the sound waves emitted from the tweeter 300 and the woofer 400 can be gathered in the sound emitting hole 1121 by conduction of the inner wall of the first receiving chamber 1011, and then guided out of the sound emitting hole 1121, thereby improving the sound coherence of the earphone 10. Furthermore, the sound emitting surfaces of the tweeter 300 and the woofer 400 may be disposed toward the sound emitting holes 1121 so that the sound emitted from the tweeter 300 and the woofer 400 can be directly emitted through the sound emitting holes 1121.

As shown in fig. 3 to 4, the tweeter 300, the woofer 400, and the sound emitting hole 1121 may be coaxially disposed to improve the sound field naturalness of the earphone 10. In some embodiments, the arrangement of the tweeter 300, the woofer 400, and the sound outlet 1121 may also be adjusted according to the specific structure of the earphone 10, which is not limited in this embodiment. Further, the tweeter 300 may be disposed between the sound outlet hole 1121 and the woofer 400 and disposed adjacent to the sound outlet hole 1121, so that the sound emitted from the tweeter 300 can be directly conducted to the outside of the earphone 10 through the sound outlet hole 1121. In this embodiment, the timbre of the tweeter 300 may be fused with the timbre of the woofer 400, thereby reducing the perception of timbre segmentation from the dual speaker output. For example, the tweeter 300 may be a flat diaphragm speaker and the woofer 400 may be a moving coil speaker. Because the magnetic conduction vibrating diaphragm material among the plane vibrating diaphragm speaker is the polymer material that the pliability is better, consequently when the coil circular telegram makes the magnetic conduction vibrating diaphragm by the magnetization atress vibration, the tone quality of its sound of giving off is more mellow and full. Compare in the tradition and move indisputable speaker and pass through the iron sheet and drive the metal vibrating diaphragm sound production for the tone quality is cold thin hard sound production mode, and the tone quality that the tone quality of plane vibrating diaphragm speaker can be better fuses mutually with the tone quality that moves the circle speaker, thereby reduces cutting apart of high frequency speaker 300 and woofer 400 on the tone quality and feels, effectively promotes earphone 10's tone quality. Simultaneously, because plane vibrating diaphragm loudspeaker are absorbed in more in the high frequency range, consequently plane vibrating diaphragm loudspeaker can compensate the not enough shortcoming of moving coil speaker high frequency extension, can very big extension high frequency response, has very big promotion at 8KHz ~ 40KHz frequency channel frequency response for earphone 10 can compromise the expressive force on low frequency range and high frequency range. The specific structure and sound-producing principle of the planar diaphragm speaker and the moving coil speaker are within the scope understandable by those skilled in the art, and the embodiments of the present application are not described herein in detail.

In addition, since the tweeter 300 is a flat diaphragm speaker and the woofer 400 is a moving coil speaker, both of which are driven by magnetic force, in order to prevent magnetic interference between the tweeter 300 and the woofer 400, a separation magnet 700 may be disposed between the tweeter 300 and the woofer 400 to isolate the magnetic interference between the tweeter 300 and the woofer 400. For example, the magnetism insulator 700 may be provided on a side of the tweeter 300 facing away from the sound outlet hole 1121, and an orthographic projection of the tweeter 300 on the magnetism insulator 700 may overlap with the magnetism insulator 700. Therefore, the isolation magnet 700 can isolate the magnetic interference between the high-frequency loudspeaker 300 and the low-frequency loudspeaker 400, and the vibration accuracy of the diaphragms of the high-frequency loudspeaker 300 and the low-frequency loudspeaker 400 is ensured. In the present embodiment, the magnetism insulator 700 may be a permanent magnet. In some embodiments, the magnetic shield 700 may also be another object capable of affecting the magnetic field between the tweeter 300 and the woofer 400.

Referring to fig. 5 to 8 in conjunction with fig. 4, fig. 5 is a schematic structural view of the front housing 110 in fig. 3, fig. 6 is a schematic structural view of the front housing 110 in fig. 3 from another view angle, fig. 7 is a schematic structural view of a cross section of the front housing 110 in fig. 6 along v-v, and fig. 8 is a partially enlarged view of a point a in fig. 5.

As shown in fig. 5 to 6, in order to mount the tweeter 300 and the woofer 400, corresponding bosses may be formed on the inner wall of the first receiving cavity 1011 to limit the tweeter 300 and the woofer 400. For example, the first receiving cavity 1011 may have a first boss 1111 and a second boss 1112 formed therein. The first boss 1111 may be used to mount the tweeter 300 and the second boss 1112 may be used to mount the woofer 400. The first boss 1111 may be disposed on an inner wall of the first receiving cavity 1011 near the sound outlet hole 1121, so that the tweeter 300 may be disposed adjacent to the sound outlet hole 1121. The second boss 1112 may be disposed on an inner wall of the first receiving cavity 1011 away from the sound outlet hole 1121, so that the woofer 400 may be disposed at an interval from the tweeter 300 to avoid structural interference when the tweeter 300 and the woofer 400 vibrate. In addition, in the present embodiment, the tweeter 300 and the woofer 400 may be adhered to the first boss 1111 and the second boss 1112 by an adhesive, so as to improve the fixing strength of the tweeter 300 and the woofer 400 to the front case 110. The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

Further, the number of the first bosses 1111 may be plural, for realizing the communication between the low frequency speaker 400 and the sound outlet hole 1121. For example, a plurality of first bosses 1111 may be annularly distributed along the inner wall of the first receiving cavity 1011, and adjacent first bosses 1111 may be spaced apart from each other. As shown in fig. 4, a gap may exist between the first bosses 1111 disposed adjacent to each other, and when the tweeter 300 is disposed on the first bosses 1111, the front case 110 and the tweeter 300 may form a sound transmission path 10111 by surrounding the gap and the first bosses 1111 disposed adjacent to each other. Thus, the sound emitted from the woofer 400 can be conducted into the sound emitting hole 1121 through the sound transmission channel 10111 to realize the sound emitting function of the woofer 400. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

As shown in fig. 8, the first boss 1111 may include a first retaining wall 11111 and a second retaining wall 11112. Wherein, the first retaining wall 11111 may be disposed to protrude from the inner wall of the first receiving cavity 1011 and extend in the first direction Y. The second retaining wall 11112 is located on a side of the first retaining wall 11111 near the sound outlet hole 1121, and extends in the second direction X. The first direction Y may be an opening direction of the sound hole 1121, and the second direction X may be a direction perpendicular to the first direction Y. Thus, the first retaining wall 11111 and the second retaining wall 11112 can form a structure similar to an "L" shape in appearance. When the tweeter 300 is disposed on the first boss 1111, the outer sidewalls of the tweeter 300 may be in contact with the first retaining wall 11111 and the second retaining wall 11112, respectively, so that the first boss 1111 may limit the tweeter 300. In addition, in order to further improve the limiting capability of the first boss 1111 on the tweeter 300, a partial region of the first retaining wall 11111 may be further protruded toward the second direction X to form a limiting pillar 11113. When tweeter 300 is positioned on first boss 1111, retaining post 11113 may abut the outer sidewall of tweeter 300 to capture tweeter 300. In this embodiment, the limiting column 11113 may be similar to a triangular prism in shape, and the corner of the limiting column 11113 may abut against the outer sidewall of the tweeter 300, so as to improve the limiting capability of the limiting column 11113 on the tweeter 300.

Accordingly, the number of the second bosses 1112 may be plural, for realizing the communication of the tweeter 300 with the circuit board 600. For example, a plurality of second bosses 1112 may be annularly distributed along the inner wall of the first receiving cavity 1011, and adjacent second bosses 1112 may be spaced apart from each other. As shown in fig. 4, a gap may exist between the second bosses 1112 arranged adjacently, and when the woofer 400 is arranged on the second bosses 1112, the front shell 110 and the woofer 400 may form the connecting channel 10112 by the gap and the second bosses 1112 arranged adjacently. Therefore, the flexible circuit board in the earphone 10 can extend from the side of the woofer 400 away from the sound outlet 1121 to the tweeter 300 through the connecting channel 10112, so as to realize the electrical connection between the circuit board 600 and the tweeter 300. In addition, the second boss 1112 may be similar in shape to the first boss, and the second boss 1112 may also include two retaining walls extending in the first direction Y and the second direction Z, respectively, to limit the low frequency speaker 400. In this embodiment, the number of the first bosses 1111 and the second bosses 1112 may be specifically set according to the actual size of the first receiving cavity 1011, and this embodiment is not limited herein.

Furthermore, as shown in fig. 1 and 2, in order to improve the comfort of the user wearing the headset 10, the headset 10 may be further provided with a contact sleeve 800, and the contact sleeve 800 may be used to contact the ear of the user. For example, the contact sleeve 800 may be disposed around the outer sidewall of the extension 112, and the contact sleeve 800 may be similar in shape to the human ear canal to improve the fit of the earphone 10. Meanwhile, the contact sleeve 800 may be made of flexible materials such as silicone rubber and rubber to improve the comfort of the user wearing the earphone 10. As shown in fig. 7, a protrusion 1122 may be further formed on the outer sidewall of the extension portion 112, so that when the contact sleeve 800 is disposed around the outer sidewall of the extension portion 112, the protrusion 1122 can be in contact with the contact sleeve 800, thereby limiting the contact sleeve 800 and reducing the probability that the contact sleeve 800 naturally falls off from the extension portion 112. The terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 9 to 11, fig. 9 is a schematic structural view of the rear housing 120 of fig. 2, fig. 10 is a schematic structural view of an assembly of a portion of the front housing 110 and the bracket 200 of fig. 2, and fig. 11 is a schematic structural view of a cross-section of a portion of the front housing 110 and the bracket 200 of fig. 10 along line iv-iv.

As shown in fig. 9, the rear case 120 is connected with the front case 110 to enclose the first receiving chamber 1011. Meanwhile, the rear case 120 may also be used to mount the battery 500 and the circuit board 600. The rear case 120 may include a cover 121 and a lever body 122 that are integrally formed. The cover 121 may cover the first receiving cavity 1011 to close the first receiving cavity 1011. The rod 122 may be disposed on a side of the cover 121 away from the front shell 110. Cover 121 may be used to mount battery 500 and circuit board 600. For example, the cover 121 may have a second receiving cavity 1012 configured to receive the battery 500 and the circuit board 600, and the second receiving cavity 1012 may communicate with the first receiving cavity 1011, which together form the receiving space 101. Besides the battery 500 and the circuit board 600, the second receiving cavity 1012 can be used for receiving functional devices such as an antenna, a communication unit and a sensor, so as to realize wireless connection between the earphone 10 and other electronic devices. A charging contact may be disposed on the rod 122 to charge the earphone 10 with an external power source. Meanwhile, a space communicated with the second accommodating cavity 1012 may be formed in the rod body 122, and a corresponding charging circuit may be disposed in the space, so that the charging contact may be electrically connected to the circuit board 600 in the second accommodating cavity 1012.

As shown in fig. 10 to 11, the bracket 200 may be disposed in the accommodating space 101, and the bracket 200 may be used to separate the first accommodating cavity 1011 and the second accommodating cavity 1012. For example, the bracket 200 may provide a region where the front case 110 and the rear case 120 are connected, and the bracket 200 may be connected with the inner walls of the first receiving chamber 1011 and the second receiving chamber 1012, respectively. Therefore, the bracket 200 can separate the first accommodating cavity 1011 and the second accommodating cavity 1012, so that the high-frequency loudspeaker 300 and the low-frequency loudspeaker 400 can be independently arranged in the first accommodating cavity 1011, and the probability that the vibration and the sound of the high-frequency loudspeaker 300 and the low-frequency loudspeaker 400 affect other electronic devices is reduced. Meanwhile, the bracket 200 may also be matched with the rear case 120 to perform a limit installation of the battery 500 and the circuit board 600. I.e. the holder 200 may also be used to carry the battery 500 and the circuit board 600. In this embodiment, the stand 200 may be further spaced apart from the woofer 400 to form a gap, so that the earphone 10 may form the rear sound chamber 1013 of the woofer 400 by using the gap to improve the sound quality of the earphone 10.

According to the earphone 10 provided by the embodiment of the application, the high-frequency loudspeaker 300 and the low-frequency loudspeaker 400 are arranged in the first accommodating cavity 1101 of the front shell 110, so that the earphone 10 can give consideration to expressive force in a low-frequency sound range and a high-frequency sound range. Meanwhile, the high frequency loudspeaker 300 is a plane diaphragm loudspeaker, so that the timbres of the low frequency loudspeaker 400 and the high frequency loudspeaker 300 can be fused, the segmentation feeling of the low frequency loudspeaker 400 and the high frequency loudspeaker 300 on the timbre can be reduced, and the timbre of the earphone 10 can be improved.

The above description is only a part of the embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent devices or equivalent processes performed by the content of the present application and the attached drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
