DETAILED DESCRIPTION

[0045] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0046] Electronic devices such as mobile phones, tablets, smart watches, etc., generally add earpiece parts to the electronic devices in order to improve the anti-eavesdropping performance.

[0047] In the related art, two periosteums in the earpiece part are often arranged at intervals to provide a waterproof layer in the gap, which will affect the sound propagation effect of the earpiece part and affect the user's hearing experience.

[0048] Based on this, the present application provides an electronic device, such as Figure 1 , Figure 2 As shown, it includes a housing 200 and an audio module 100. Figure 3As shown, the audio module 100 includes: a sound-producing body 110, a connecting body 120, a second vibrating member 130 and a transmission member 140. The housing 200 is fixedly connected to the connecting body 120. The sound-producing body 110 includes a first vibrating member 111 and a magnetic driving member 112 that cooperates with the magnetic excitation of the first vibrating member 111, and the magnetic driving member 112 is used to drive the first vibrating member 111 to vibrate and produce sound. The connecting body 120 is fixedly connected to the sound-producing body 110, and the connecting body 120 includes a hollow hole 121. The second vibrating member 130 is arranged on the connecting body 120, and is arranged opposite to the first vibrating member 111 along the depth direction of the hollow hole 121. The transmission member 140 is arranged between the first vibrating member 111 and the second vibrating member 130, and the transmission member 140 is at least partially arranged in the hollow hole 121, so that the first vibrating member 111 transmits sound waves to the second vibrating member 130 through the transmission member 140.

[0049] It can be understood that the magnetic drive member 112 drives the first vibrating member 111, and then the first vibrating member 111 transmits sound waves to the second vibrating member 130 through the transmission member 140, so as to drive the second vibrating member 130 to vibrate and realize sound propagation. In this way, the transmission member 140 acts as a propagation conductor of sound waves between the first vibrating member 111 and the second vibrating member 130, which is different from air propagation. The transmission member 140 can speed up the sound propagation efficiency between the first vibrating member 111 and the second vibrating member 130, reduce sound wave loss, and ensure the sound propagation effect.

[0050] Furthermore, the transmission member 140 is at least partially disposed in the hollow hole 121, so that at least a portion of the hollow hole 121 can serve as a sound wave propagation space between the first vibrator 111 and the second vibrator 130, which is different from the direct connection between the first vibrator 111 and the second vibrator 130. The existence of the sound wave propagation space is conducive to enhancing the low-frequency component and thus achieving a more shocking audio experience.

[0051] In addition, the vibration frequency can be adjusted by adjusting the current of the magnetic driving component 112, so as to provide audio with different volumes, while also avoiding continuous vibration and extending the service life of the audio module 100.

[0052] In one example, the sound-generating component is a piezoelectric speaker. In this way, the advantages of the piezoelectric speaker, such as simple structure, small size, and low cost, can be fully utilized, which is conducive to reducing the cost of the terminal device and meeting the miniaturization development of the terminal device. Furthermore, the terminal device of the present application has the advantages of small size, light weight, and low power consumption while having the speaker sound-generating function and the earpiece sound-generating function, which is conducive to gaining the favor of consumers and further improving the competitiveness of the product.

[0053] It should be noted that the first vibrator and the second vibrator may be a vibrating periosteum or a vibrating suspension, etc.

[0054] In some embodiments, the first vibrator and the second vibrator may be vibrating periosteum. In this way, the vibrating periosteum can make the audio module more delicate in terms of sound quality. At the same time, the vibrating periosteum is easier to drive, and allowing the vibrating periosteum to fully vibrate will increase the sensitivity of the sound.

[0055] The electronic device may be, but is not limited to, a mobile phone, and may also be a tablet, a smart watch, or an MP4, etc. In addition, by connecting the connecting body 120 to the housing 200 , the vibration loss between the housing 200 and the connecting body 120 can be reduced, and the propagation effect of the sound can be optimized.

[0056] Reference Figure 4 As shown, in some embodiments, the magnetic driving member 112 includes a magnet 1121 and a magnetic ring 1122 that is sleeved with the magnet 1121, and the magnetic ring 1122 and the magnet 1121 are spaced apart to form a first gap; the sound body 110 also includes a folding ring 1223 and a voice coil 1124 that is fixedly connected to the first vibrating member 111, the voice coil 1124 is movably arranged in the first gap, and the first vibrating member 111 is fixedly connected to the magnetic ring 1122 through the folding ring 1223. In this way, when the sound body 110 is powered on, the driving current can cause the voice coil 1124, the magnetic ring 1122 and the magnet 1121 to vibrate up and down, so as to drive the first vibrating member 111 to vibrate, and realize the sound of the sound body 110.

[0057] In some embodiments, see the attached Figure 2 The housing 200 includes a middle frame 210, and the middle frame 210 is integrally formed with the connection body 120. In this way, the gap between the middle frame 210 and the connection body 120 can be reduced to prevent dust and the like from entering. In addition, the connection strength of the integrated production is better, which is conducive to improving the structural strength of the audio module 100.

[0058] It should be noted that the transmission member 140 can be a rigid metal member, an elastic member, etc., and no further limitation is given here.

[0059] In some embodiments, the transmission member 140 includes an elastic transmission part 141, and the first vibrating member 111 is transmission-connected to the second vibrating member 130 via the elastic transmission part 141. In this way, unlike the setting of a rigid metal member, the first vibrating member 111 is transmission-connected to the second vibrating member 130 via the elastic transmission part 141, so that when the first vibrating member 111 transmits sound waves to the second vibrating member 130, the elastic transmission part 141 can be elastically transformed and retracted to shorten the delay frequency when the vibration changes. Furthermore, during the elastic transformation and retraction process of the elastic transmission part 141, it can also play a buffering role in the transmission of sound waves between the first vibrating member 111 and the second vibrating member 130, avoiding excessive collision with other parts, thereby delaying the service life of the audio module 100.

[0060] It should be noted that the elastic transmission part 141 can be realized by providing a spring or providing elastic plastic, etc., which is not further limited here.

[0061] In combination with any of the above embodiments of the elastic transmission part 141, in some embodiments, as shown in the attached Figure 5 As shown, the elastic transmission part 141 includes a folded elastic member 1411, and the first vibrating member 111 is transmission-connected with the second vibrating member 130 via the folded elastic member 1411. In this way, transmission is achieved by setting the folded elastic member 1411, and the folded elastic member 1411 has a plurality of folded spaces, a good buffering effect, a simple structure, and is easy to process.

[0062] It should be noted that the folding elastic member 1411 may be a spring or an elastic suspension wire. Figure 5 As shown, the folded elastic member 1411 can be an elastic suspension wire. Thus, unlike a spring, the elastic suspension wire occupies less space, so that the hollow hole 121 can have more space, which is conducive to improving the low-frequency component, thereby achieving a more shocking audio experience.

[0063] It should be noted that the second vibrating member 130 may be disposed in the hollow hole 121 , or may be disposed to cover the hollow hole 121 , etc., and no further limitation is made herein.

[0064] In combination with any of the above-mentioned embodiments of the second vibrating member 130, in some embodiments, see the attached Figure 3 , the connecting body 120 also includes a mating surface 122 arranged on the outer edge of the hollow hole 121, the mating surface 122 is arranged away from the first vibrating member 111, and the second vibrating member 130 is arranged on the mating surface 122 and covers the hollow hole 121. It can be understood that the mating surface 122 is fixedly connected to the shell 200, and the user's ear is close to the shell 200, and the user listens to the audio changes through the vibration transmission on the shell 200. In this way, the second vibrating member 130 is arranged on the mating surface 122, so that the second vibrating member 130 can be fixedly connected to the shell 200, drive the vibration of the shell 200, and realize sound propagation. Different from the propagation between the second vibrating member 130 and the shell 200 through a medium such as air, it can reduce the loss of sound wave energy and optimize the quality of sound propagation.

[0065] In combination with any of the above-mentioned embodiments of the connection body 120, in some embodiments, see the attached Figure 3The second vibrating member 130 is provided with a dustproof layer 131, and the dustproof layer 131 covers the hollow hole 121. In this way, by providing the dustproof layer 131, dust particles can be prevented from entering the audio module 100 through the hollow hole 121, thereby preventing interference with the audio module 100 and ensuring the service life of the audio module 100. Furthermore, the second vibrating member 130 is provided with a dustproof layer 131, which can achieve the dustproof effect without the need to provide an additional dustproof component, thereby reducing the space occupied by components and reducing the manufacturing cost.

[0066] It should be noted that the dustproof layer 131 can be, but is not limited to, a dustproof net, and can also be a PTFE filter membrane, etc., and no further limitation is made here.

[0067] In one example, the dustproof net can be used as the second vibrating member 130, so that there is no need to set up a periosteum or the like to achieve sound wave transmission, which can reduce the production cost.

[0068] In another example, the second vibrator 130 may be a dustproof membrane, so that the second vibrator 130 can transmit sound more sensitively and achieve dustproof effect without additional dustproof components, thereby reducing the space occupied by components and reducing the manufacturing cost.

[0069] In combination with any of the above-mentioned embodiments of the connection body 120, in some embodiments, see the attached Figure 5 The audio module 100 further includes a sealing member 150, which is sandwiched between the sound body 110 and the connecting body 120 and arranged around the hollow hole 121. Thus, by arranging the sealing member 150 between the sound body and the connecting body 120, it is possible to prevent moisture from entering the audio module 100 through the hollow hole 121, thereby affecting the working state of the magnetic driving member 112, and ensuring the service life of the magnetic driving member 112.

[0070] In addition, the sealing member is arranged around the hollow hole, so that the length distribution of the sealing member near the hollow hole can be consistent and more evenly distributed, which is beneficial to improving the uniformity of the sealing performance.

[0071] It should be noted that the sealing member 150 may be a silicone ring, a rubber ring, etc. At the same time, the number of the sealing members 150 may be one or more, and no excessive restrictions are imposed on the former.

[0072] In combination with any of the above embodiments of the sealing member 150, the number of the sealing member 150 may be one. Figure 5At least one of the sounding body 110 and the connecting body 120 is provided with an annular recess 160, which is arranged around the outer circumference of the first vibrating member 111 and the transmission member 140, and a portion of the seal 150 is embedded in the annular recess 160, so that the seal 150 is sandwiched between the sounding body 110 and the connecting body 120. In this way, through the cooperation between the annular recess 160 and the seal 150, the annular recess 160 can provide a positioning function for the installation of the seal 150, making the installation of the seal 150 faster and more convenient.

[0073] Furthermore, the annular recess 160 can reduce the matching clearance of the seal 150 between the sound-generating body 110 and the connecting body 120 , thereby improving the sealing effect and achieving a better waterproof and dustproof effect.

[0074] In addition, the annular recess 160 is arranged around the outer periphery of the first vibrating member 111 and the transmission member 140, that is, the sealing member 150 is arranged around the hollow hole 121, so that moisture and dust can be prevented from dispersing outside the hollow hole 121 to the connecting body 120 or the sounding body 110, thereby improving the sealing performance of the audio module 100.

[0075] In one example, the seal 150 may include silica gel, which can be waterproof and absorb moisture, thereby ensuring a dry environment in the audio module 100 at all times and avoiding interference with the operation of the audio module 100.

[0076] It should be noted that the annular recess 160 may be provided on the connecting body 120 , the sound producing body 110 , or both, which is not further limited herein.

[0077] In some embodiments, see the attached Figure 5 , the connecting body 120 and the sounding body 110 are both provided with an annular recess 160. It can be understood that the seal 150 is sandwiched between the two annular recesses 160. In this way, through the provision of the annular recess 160 and the matching hole 1611, the positioning effect of the seal 150 can be increased, and the efficiency of disassembly and assembly of the seal 150 can be improved.

[0078] Furthermore, the matching clearance between the seal 150 and the connecting body 120 and the sounding body 110 can be reduced, thereby improving the sealing performance of the audio module 100 and ensuring the service life of the audio module 100.

[0079] It should be noted that the annular recess 160 may be, but is not limited to, a groove 162 , and may also be a concave hole, etc., which is not further limited herein.

[0080] In combination with any of the above embodiments of the sealing member 150, the number of the sealing member 150 may be multiple. Figure 6 As shown, the annular recess 160 includes at least one group of hole units 161, and the hole unit 161 includes at least one matching hole 1611 arranged at intervals around the outer circumference of the hollow hole 121. The sounding body 110 and the seal 150 are abutted against each other so that a part of the seal 150 is embedded in the matching hole 1611. In this way, the annular recess 160 can be the matching hole 1611, and the seal 150 is positioned one by one through the matching hole 1611, which can enhance the installation stability of the seal 150. Furthermore, it can reduce the excessive processing of at least one of the connecting body 120 and the sounding body 110, and the finished product is more convenient to manufacture.

[0081] In some other embodiments, see the attached Figure 5 The sound body 110 includes a first annular recess 160, which includes a groove 162; the connecting body 120 includes a second annular recess 160, which includes a groove 162, and the sealing member 150 is sandwiched between the groove 162 and the matching hole 1611. In this way, it can be understood that the matching of the groove 162 and the matching hole 1611 makes it unnecessary to set the matching hole 1611 on both the connecting body 120 and the sound body 110, and further, it is unnecessary to align the matching holes 1611 of the connecting body 120 and the sound body 110, and fixation can be achieved, which can reduce the processing difficulty of the audio module 100 and improve the processing efficiency.

[0082] It should be noted that the number of hole units 161 can be one group or multiple groups, and no further limitation is made here.

[0083] In combination with any of the above embodiments of the annular recess 160, the annular recess 160 may include a plurality of groups of hole units 161. Figure 6 , the annular recess 160 includes at least two groups of hole units 161, and the at least two groups of hole units 161 are arranged at staggered intervals. In this way, the arrangement of at least two groups of hole units 161 can increase the number of seals 150 in the cross section between the connecting body 120 and the sounding body 110, thereby enhancing the sealing performance between the connecting body 120 and the sounding body 110. Further, the at least two groups of hole units 161 are arranged at staggered intervals, which can reduce the number of seals 150 in the longitudinal section between the connecting body 120 and the sounding body 110, thereby enhancing the sealing performance between the connecting body 120 and the sounding body 110.

[0084] In some other embodiments, see the attached Figure 7As shown, at least two groups of hole units 161 are spaced apart from each other along the center of the hollow hole 121 toward the outside. In this way, at least two groups are spaced apart from each other along the center of the hollow hole 121 toward the outside, which can increase the number of seals 150 between the connecting body 120 and the sounding body 110, thereby improving the sealing performance between the connecting body 120 and the sounding body 110. Furthermore, this arrangement makes the arrangement more neat and beautiful, which is conducive to improving the aesthetics of the audio module 100.

[0085] It should be noted that the cooperation between the sealing member 150 and the hole unit 161 can be partial covering or complete covering, which is not further limited here.

[0086] In combination with any of the above embodiments of the hole unit 161, in some embodiments, the seal 150 covers all the hole units 161. In this way, the seal 150 corresponds to the number of matching holes 1611 in the hole unit 161, thereby improving the sealing performance between the connection body 120 and the sound body 110. Furthermore, the seal 150 can completely cover the matching hole 1611, which can reduce the matching gap between the matching hole 1611 and the seal 150, thereby improving the installation stability of the seal 150 in the matching hole 1611, which is beneficial to the sealing performance of the audio module 100.

[0087] In conjunction with any of the above embodiments of the annular recess 160, the annular recess 160 may include a groove 162. Figure 5 , the annular recess 160 includes a groove 162 and a plurality of protrusions 163 arranged in the groove 162. A portion of the seal 150 is embedded in the groove 162 and abuts against the protrusion 163. It can be understood that the seal 150 has a certain elastic deformation performance, so that when a portion of the seal 150 is embedded in the groove 162 and abuts against the protrusion 163, the protrusion 163 produces a certain elastic deformation on the seal 150. In this way, an internal driving force is generated in the seal 150, so that the sound-generating body 110 and the connecting body 120 can be pressed, thereby improving the installation stability of the seal 150. Furthermore, the sealing matching gap between the sound-generating body 110 and the connecting body 120 can be reduced, thereby improving the sealing performance of the audio module 100.

[0088] It should be noted that the fixed connection between the sounding body 110 and the connecting body 120 can be achieved by a non-detachable method such as welding or bonding, or a detachable method such as snap connection or screw connection, which is not limited here.

[0089] In combination with any of the above-mentioned embodiments of the sounding body 110 and the connecting body 120, in some embodiments, see the attached Figure 5One of the sound body 110 and the connection body 120 is provided with a mounting portion 170, and the other is provided with a matching portion 180. The sound body 110 and the connection body 120 are fixedly connected through the detachable connection of the mounting portion 170 and the matching portion 180. In this way, the sound body 110 and the connection body 120 are fixedly connected through the detachable matching of the mounting portion 170 and the matching portion 180. The detachable fixed connection method is conducive to improving the disassembly and assembly efficiency of the sound body 110 and the connection body 120, and is convenient for replacing parts or cleaning the interior of the audio module 100.

[0090] In some embodiments, the sounding component further includes a fastener 190, and the mounting portion 170 is fixedly connected to the matching portion 180 through the fastener 190. In this way, by setting the fastener 190, the detachable connection is realized in contrast to the snap-fit ​​connection, which can reduce the difficulty of processing the connecting body 120 and the sounding body 110, and is conducive to reducing processing costs and improving processing efficiency. Furthermore, the connection strength between the mounting portion 170 and the matching portion 180 can be improved, which is conducive to improving the connection stability of the audio module 100.

[0091] In an example, see the attached Figure 5 The fastener 190 is a bolt 191, the mounting portion 170 is provided with a first through hole 171, the matching portion 180 is provided with an internal threaded hole 181 corresponding to the first through hole 171, and the fastener 190 passes through the first through hole 171 and is threadedly matched with the internal threaded hole 181 to fix the sound body 110 and the connecting body 120. In another example, see the attached Figure 8 , the fastener 190 is a bolt 191, the audio module 100 also includes a nut 192 matched with the bolt 191, the mounting portion 170 is provided with a second through hole 172, the matching portion 180 is provided with a third through hole 182 corresponding to the second through hole 172, and the fastener 190 passes through the second through hole 172 and the third through hole 182 and is screwed with the nut 192 to fix the sound body 110 and the connecting body 120. In this way, different from the magnetic fixation and other methods achieved by the fastener 190, the screw connection between the fastener 190 and the internal threaded hole 181 or the fastener 190 and the bolt 191 has a stronger connection strength and a more stable connection, which can improve the connection strength and stability of the mounting portion 170 and the matching portion 180. In addition, the above embodiments can be selected according to different generation scenarios, and are not excessively limited here.

[0092] It should be noted that the shape of the sounding body 110 can be a block or an irregular shape, which is not further limited here.

[0093] In combination with any of the above embodiments of the pronunciation body 110, in some embodiments, see the attached Figure 5The sounding body 110 includes a first body 113 and a second body 114, and the first body 113 is arranged to protrude from the second body 114. The first vibrating member 111 and the magnetic driving member 112 are arranged on the first body 113, the mounting portion 170 is arranged on the second body 114, and the matching portion 180 is arranged on the connecting body 120. It can be understood that the first body 113 is arranged to protrude from the second body 114, so that the first body 113 and the second body 114 are in a "convex" shape. In this way, the thickness of the first body 113 is relatively thick, and there is more accommodation space to accommodate the magnetic driving member 112 and the first vibrating member 111. Furthermore, the thickness of the second body 114 is less than that of the first body 113, so that the mounting portion 170 is arranged on the second body 114, which is different from the processing of the mounting portion 170 on the first body 113, which can reduce the processing difficulty while avoiding processing interference to the magnetic driving member 112 and the first vibrating member 111.

[0094] It should be noted that the number of the mounting portion 170 and the matching portion 180 can be one group or multiple groups, and no further limitation is given here.

[0095] In combination with any of the above-mentioned embodiments of the mounting portion 170 and the matching portion 180, in some embodiments, see the attached Figure 6 At least three mounting portions 170 are arranged at intervals on the second body 114, at least three matching portions 180 are arranged at intervals on the connecting body 120, and the mounting portions 170 and the matching portions 180 are fixedly connected one by one to fix the sounding body 110 and the connecting body 120. It can be understood that at least three mounting portions 170 are arranged at intervals on the second body 114, so that at least three mounting portions 170 form at least one mounting surface on the second body 114, that is, there is a surface fixation between the second body 114 and the connecting body 120. In this way, it is beneficial to improve the connection tightness between the second body 114 and the connecting body 120.

[0096] In an example, see the attached Figure 6 , the first body 113 is arranged in a square shape, and at least four mounting portions 170 are arranged at intervals on the second body 114 and respectively arranged around the four sides of the first body 113. Figure 7 The first body 113 is distributed in a square shape, and at least four mounting portions 170 are arranged at intervals on the second body 114 and close to the four corners of the first body 113 .
