Description

Technical Field

[0001] This application relates to the field of electronic technology, and in particular to an audio module and electronic device. Background Technology

[0002] Currently, many electronic devices are equipped with earpieces to improve their anti-eavesdropping capabilities.

[0003] In related technologies, in order to improve the waterproof performance of earpiece components, earpiece components are often provided with a waterproof layer. This causes the active and passive diaphragms in the earpiece components to be affected by the spatial position of the waterproof layer, and the two are set at intervals. The active diaphragm transmits sound waves to the passive diaphragm through the air.

[0004] This setup, due to its poor sound transmission through the air, ultimately affects the sound wave propagation effect of the earpiece components, greatly impacting the user experience. Summary of the Invention

[0005] This application provides an audio module and electronic device. It helps improve sound propagation and optimize the user's auditory experience.

[0006] The technical solution is as follows:

[0007] According to a first aspect of the embodiments of this application, an audio module is provided, including a sound-producing body, a connecting body, a second vibrating member, and a transmission member. The sound-producing body includes a first vibrating member and a magnetic drive member that magnetically excites and cooperates with the first vibrating member, the magnetic drive member driving the first vibrating member to vibrate and produce sound. The connecting body is fixedly connected to the sound-producing body, and the connecting body includes a hollow hole. The second vibrating member is disposed on the connecting body and is disposed opposite to the first vibrating member along the depth direction of the hollow hole. The transmission member is disposed between the first and second vibrating members, and at least partially disposed within the hollow hole, so that the first vibrating member transmits sound waves to the second vibrating member through the transmission member.

[0008] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0009] In use, this audio module uses a magnetic drive to drive a first vibrator, which then transmits sound waves to a second vibrator via a transmission component. This causes the second vibrator to vibrate, thus propagating sound. The transmission component acts as a conductor for sound wave propagation between the first and second vibrators, unlike air propagation. This transmission component accelerates sound propagation between the two vibrators, reduces sound wave loss, and ensures optimal sound transmission. Furthermore, the transmission component is at least partially located within a perforated hole, allowing at least a portion of the hole to serve as a space for sound wave propagation between the first and second vibrators. Unlike a direct connection between the two vibrators, this propagation space enhances low-frequency components, resulting in a more immersive audio experience. Additionally, the vibration frequency can be adjusted by regulating the current in the magnetic drive, providing different audio volumes while preventing continuous vibration and extending the lifespan of the audio module.

[0023] In one embodiment, the fastener is a bolt, the mounting part is provided with a first through hole, and the mating part is provided with an internal threaded hole corresponding to the first through hole.

The mounting part has a second through hole, and the mating part has a third through hole that corresponds to the second through hole. The fastener passes through the second through hole and the third through hole and is screwed into the nut to fix the sound body and the connecting body together.

Detailed Implementation

[0045] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0046] To improve their anti-eavesdropping capabilities, electronic devices such as mobile phones, tablets, and smartwatches typically incorporate earpiece components.

[0047] In related technologies, the two diaphragms in the earpiece are often spaced apart to create a waterproof layer in the gap. However, this method affects the sound propagation effect of the earpiece and impacts the user's auditory experience.

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

[0049] Understandably, the magnetic drive component 112 drives the first vibrating component 111, which in turn transmits sound waves to the second vibrating component 130 via the transmission component 140, causing the second vibrating component 130 to vibrate and thus propagating sound. In this way, the transmission component 140 acts as a conductor for sound wave propagation between the first vibrating component 111 and the second vibrating component 130. Unlike air propagation, the transmission component 140 accelerates the sound propagation efficiency between the first vibrating component 111 and the second vibrating component 130, reduces sound wave loss, and ensures effective sound propagation.

[0050] Furthermore, the transmission component 140 is at least partially disposed in the hollow hole 121, so that at least part of the hollow hole 121 can serve as a sound wave propagation space between the first vibrating component 111 and the second vibrating component 130. Unlike the direct connection between the first vibrating component 111 and the second vibrating component 130, the existence of the sound wave propagation space is beneficial to enhancing the low-frequency components, thereby achieving a more immersive audio experience.

[0051] In addition, the vibration frequency can be adjusted by regulating the current of the magnetic drive 112, thereby providing audio at different volumes and avoiding continuous vibration, thus extending the service life of the audio module 100.

[0052] In one example, the sound-generating component is a piezoelectric loudspeaker. This fully utilizes the advantages of piezoelectric loudspeakers, such as simple structure, small size, and low cost, which helps reduce the cost of terminal devices and meet the miniaturization requirements of terminal devices. Furthermore, the terminal device of this application, while possessing both loudspeaker and earpiece sound-generating functions, also has the advantages of small size, light weight, and low power consumption, making it more attractive to consumers and further enhancing product competitiveness.

[0053] It should be noted that the first and second vibrating components can be vibrating diaphragms or vibrating suspensions, etc.

[0054] In some embodiments, the first and second vibrating elements can be a vibrating diaphragm. This allows the vibrating diaphragm to produce more delicate sound quality. Simultaneously, the vibrating diaphragm is easier to drive, and allowing it to vibrate fully increases sound sensitivity.

[0055] The electronic device can be, but is not limited to, a mobile phone, and can also be a tablet, smartwatch, or MP4 player, etc. Furthermore, by connecting the main body 120 to the housing 200, vibration loss between the housing 200 and the main body 120 can be reduced, optimizing sound propagation.

[0056] Reference Figure 4 As shown, in some embodiments, the magnetic drive component 112 includes a magnet 1121 and a magnetic ring 1122 that is sleeved and fitted with the magnet 1121, with a first gap formed between the magnetic ring 1122 and the magnet 1121; the sound-producing body 110 also includes a folded ring 1223 and a voice coil 1124 fixedly connected to the first vibrating component 111, the voice coil 1124 being movably disposed in the first gap, and the first vibrating component 111 being fixedly connected to the magnetic ring 1122 via the folded ring 1223. Thus, when the sound-producing body 110 is energized, the driving current can cause the voice coil 1124, the magnetic ring 1122, and the magnet 1121 to vibrate up and down, thereby driving the first vibrating component 111 to vibrate, and realizing the sound production of the sound-producing body 110.

[0057] In some embodiments, see Appendix Figure 2 The housing 200 includes a middle frame 210, which is integrally formed with the connecting body 120. This reduces the gap between the middle frame 210 and the connecting body 120, preventing dust and other contaminants from entering. Furthermore, the integrated manufacturing process provides better connection strength, which helps improve the structural strength of the audio module 100.

[0058] It should be noted that the transmission component 140 can be a rigid metal component, an elastic component, etc., and no further limitations are made here.

[0059] In some embodiments, the transmission component 140 includes an elastic transmission section 141, through which the first vibrating component 111 is connected to the second vibrating component 130. Thus, unlike the use of rigid metal components, the connection between the first vibrating component 111 and the second vibrating component 130 via the elastic transmission section 141 allows the elastic transmission section 141 to elastically expand and contract when the first vibrating component 111 transmits sound waves to the second vibrating component 130, shortening the delay frequency during vibration changes. Furthermore, the elastic transmission section 141, during its elastic expansion and contraction, can also buffer the sound wave transmission between the first vibrating component 111 and the second vibrating component 130, preventing excessive collisions with other components and thereby extending the service life of the audio module 100.

[0060] It should be noted that the elastic transmission part 141 may be implemented by setting a spring or by setting an elastic plastic, etc., and no further limitation is made here.

[0061] In conjunction with any embodiment of the elastic transmission unit 141 described above, in some embodiments, as shown in the appendix Figure 5 As shown, the elastic transmission unit 141 includes a folding elastic element 1411, and the first vibrating element 111 is connected to the second vibrating element 130 via the folding elastic element 1411. Thus, transmission is achieved through the folding elastic element 1411. The folding elastic element 1411 has several folding spaces, provides good cushioning, and has a simple structure that is easy to manufacture.

[0062] It should be noted that the folding elastic element 1411 can be a spring or an elastic suspension wire, etc. In one example, as shown in the attached... Figure 5 As shown, the folding elastic element 1411 can be an elastic suspension wire. Thus, unlike a spring, the elastic suspension wire occupies less space, allowing more space for the cutout hole 121, which is beneficial for enhancing low-frequency components and achieving a more immersive audio experience.

[0063] It should be noted that the second vibrating element 130 may be disposed within the hollow hole 121 or may be disposed covering the hollow hole 121, etc., without further limitation.

[0064] In conjunction with any of the embodiments of the second vibrating element 130 described above, in some embodiments, see Appendix Figure 3 The connecting body 120 also includes a mating surface 122 disposed on the outer edge of the hollow hole 121. The mating surface 122 is disposed away from the first vibrating member 111. The second vibrating member 130 is disposed 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 housing 200, and the user's ear is pressed against the housing 200, transmitting sound through vibrations in the housing 200. Thus, the second vibrating member 130, disposed on the mating surface 122, can be fixedly connected to the housing 200, causing the housing 200 to vibrate and thus propagating sound. Unlike other systems where sound propagation between the second vibrating member 130 and the housing 200 requires a medium such as air, this arrangement reduces sound wave energy loss and optimizes the quality of sound propagation.

[0065] In conjunction with any of the above embodiments of the connecting body 120, in some embodiments, see Appendix Figure 3The second vibrating element 130 is provided with a dustproof layer 131, which covers the perforated hole 121. Thus, the dustproof layer 131 prevents dust particles from entering the audio module 100 through the perforated hole 121, thereby preventing interference with the audio module 100 and ensuring its service life. Furthermore, the dustproof layer 131 on the second vibrating element 130 eliminates the need for additional dustproof components, reducing the space occupied by parts and lowering manufacturing costs.

[0066] It should be noted that the dustproof layer 131 can be, but is not limited to, a dustproof net, or a PTFE filter membrane, etc., without further restrictions.

[0067] In one example, the dustproof net can serve as a second vibrating element 130, eliminating the need for additional periosteum or other components to transmit sound waves, thus reducing manufacturing costs.

[0068] In another example, the second vibrator 130 can be a dustproof diaphragm. This allows the second vibrator 130 to transmit sound more sensitively, while achieving a dustproof effect without the need for additional dustproof components, reducing the space occupied by parts and lowering manufacturing costs.

[0069] In conjunction with any of the above embodiments of the connecting body 120, in some embodiments, see Appendix Figure 5 The audio module 100 also includes a seal 150, which is sandwiched between the speaker body 110 and the connector body 120 and surrounds the perforated hole 121. Thus, by positioning the seal 150 between the speaker body 110 and the connector body 120, moisture is prevented from entering the audio module 100 through the perforated hole 121, thereby affecting the working state of the magnetic drive component 112 and ensuring the service life of the magnetic drive component 112.

[0070] In addition, the sealing element is arranged around the hollow hole, which makes the length distribution of the sealing element near the hollow hole more uniform and helps to improve the uniformity of sealing performance.

[0071] It should be noted that the seal 150 can be a silicone ring, rubber ring, etc. Furthermore, the number of seals 150 can be one or multiple; no further restrictions are placed on the former.

[0072] In any of the embodiments of the seal 150 described above, the number of seals 150 may be one. In some embodiments, see Appendix Figure 5At least one of the sound-producing body 110 and the connecting body 120 is provided with an annular recess 160. The annular recess 160 is arranged around the outer periphery of the first vibrating member 111 and the transmission member 140. A portion of the sealing member 150 is embedded in the annular recess 160, and the sealing member 150 is sandwiched between the sound-producing body 110 and the connecting body 120. In this way, through the cooperation between the annular recess 160 and the sealing member 150, the annular recess 160 can provide a positioning function for the installation of the sealing member 150, making the installation of the sealing member 150 faster and more convenient.

[0073] Furthermore, the annular recess 160 can reduce the mating gap between the seal 150 and the sound-producing body 110 and the connecting body 120, thereby improving the sealing effect and providing better waterproof and dustproof performance.

[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 spreading outward at 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 silicone. Thus, by including silicone in the seal 150, it is possible to waterproof while absorbing moisture, ensuring a dry environment inside the audio module 100 at all times and preventing 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, without further limitation here.

[0077] In some embodiments, see Appendix Figure 5 Both the connecting body 120 and the sound-producing body 110 are provided with annular recesses 160. It can be understood that the sealing element 150 is sandwiched between the two annular recesses 160. In this way, the positioning effect of the sealing element 150 can be enhanced by the setting of the annular recesses 160 and the mating hole 1611, thereby improving the efficiency of disassembling and assembling the sealing element 150.

[0078] Furthermore, the fitting gap between the seal 150 and the connecting body 120 and the sound-producing 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, or a concave hole, etc., without further limitation.

[0080] In conjunction with any of the embodiments of the seal 150 described above, the number of seals 150 may be multiple. For some embodiments, see the appendix. Figure 6 As shown, the annular recess 160 includes at least one set of hole units 161. Each hole unit 161 includes at least one mating hole 1611 spaced apart around the outer periphery of the hollow hole 121. The sound-producing body 110 abuts against the sealing member 150 so that a portion of the sealing member 150 is embedded in the mating hole 1611. Thus, the annular recess 160 can be a mating hole 1611, and by positioning the sealing member 150 one by one through the mating holes 1611, the installation stability of the sealing member 150 can be enhanced. Furthermore, excessive processing of at least one of the connecting body 120 and the sound-producing body 110 can be reduced, making the finished product manufacturing more convenient.

[0081] In other embodiments, see Appendix Figure 5 The sound-producing body 110 includes a first annular recess 160, which includes a groove 162; the connecting body 120 includes a second annular recess 160, which also includes a groove 162; and the sealing member 150 is sandwiched between the groove 162 and the mating hole 1611. Thus, it can be understood that the mating of the groove 162 and the mating hole 1611 eliminates the need for both the connecting body 120 and the sound-producing body 110 to have mating holes 1611, thereby eliminating the need for alignment and machining of the mating holes 1611 on the connecting body 120 and the sound-producing body 110. This allows for fixation, reducing the processing difficulty of the audio module 100 and improving processing efficiency.

[0082] It should be noted that the number of hole units 161 can be one set or multiple sets, and no further restrictions are imposed here.

[0083] In conjunction with any embodiment of the annular recess 160 described above, the annular recess 160 may include multiple sets of hole units 161. Specifically, in some embodiments, see Appendix Figure 6 The annular recess 160 includes at least two sets of hole units 161, which are staggered. This arrangement of at least two sets of hole units 161 increases the number of seals 150 in the cross-section between the connecting body 120 and the sound-producing body 110, thereby enhancing the sealing performance between them. Furthermore, the staggered arrangement of the at least two sets of hole units 161 reduces the number of seals 150 in the longitudinal section between the connecting body 120 and the sound-producing body 110, further enhancing the sealing performance between them.

[0084] In other embodiments, see Appendix Figure 7As shown, at least two sets of hole units 161 are spaced outwards from the center of the perforated hole 121. This arrangement of at least two sets of holes spaced outwards from the center of the perforated hole 121 increases the number of seals 150 between the connecting body 120 and the sound-producing body 110, thereby improving the sealing performance between them. Furthermore, this arrangement results in a neater and more aesthetically pleasing layout, enhancing the overall appearance of the audio module 100.

[0085] It should be noted that the fit between the seal 150 and the hole unit 161 can be either partial or complete coverage, and no further limitations are made here.

[0086] In conjunction with any embodiment of the aforementioned hole unit 161, in some embodiments, the seal 150 covers all hole units 161. This ensures a one-to-one correspondence between the number of seals 150 and the mating holes 1611 in the hole units 161, improving the sealing performance between the connecting body 120 and the sound-producing body 110. Furthermore, the seal 150 can completely cover the mating holes 1611, reducing the mating gap between the mating holes 1611 and the seal 150, thereby improving the installation stability of the seal 150 in the mating holes 1611 and contributing to the sealing performance of the audio module 100.

[0087] In any embodiment of the annular recess 160 described above, the annular recess 160 may include a groove 162. In some embodiments, see Appendix Figure 5 The annular recess 160 includes a groove 162 and a plurality of protrusions 163 disposed within the groove 162. A portion of the seal 150 is embedded in the groove 162 and abuts against the protrusions 163. It is understood that the seal 150 has a certain elastic deformation property, so that when the portion of the seal 150 is embedded in the groove 162 and abuts against the protrusions 163, the protrusions 163 cause a certain elastic deformation of the seal 150. This generates an internal driving force within the seal 150, allowing it to press against the speaker body 110 and the connecting body 120, improving the installation stability of the seal 150. Furthermore, it can reduce the sealing gap between the speaker body 110 and the connecting body 120, improving the sealing performance of the audio module 100.

[0088] It should be noted that the fixed connection between the sound-producing body 110 and the connecting body 120 can be achieved by non-removable methods such as welding or bonding, or by detachable methods such as snap-fit ​​or screw-fit. No further restrictions are imposed here.

[0089] In conjunction with any of the above-described embodiments of the sound-producing body 110 and the connection body 120, in some embodiments, see Appendix Figure 5The speaker body 110 and the connector body 120 each have a mounting part 170 and a mating part 180, respectively. The speaker body 110 and the connector body 120 are fixedly connected through the detachable connection of the mounting part 170 and the mating part 180. This detachable connection improves the efficiency of assembling and disassembling the speaker body 110 and the connector body 120, facilitating component replacement or internal cleaning of the audio module 100.

[0090] In some embodiments, the sound-producing component further includes a fastener 190, through which the mounting portion 170 is fixedly connected to the mating portion 180. Thus, by using the fastener 190, a detachable connection is achieved, unlike a snap-fit ​​connection, reducing the processing difficulty of the connecting body 120 and the sound-producing body 110, thereby reducing processing costs and improving processing efficiency. Furthermore, it can increase the connection strength between the mounting portion 170 and the mating portion 180, which is beneficial for improving the connection stability of the audio module 100.

[0091] In one example, see appendix. Figure 5 The fastener 190 is a bolt 191. The mounting part 170 has a first through hole 171, and the mating part 180 has an internal threaded hole 181 corresponding to the first through hole 171. The fastener 190 passes through the first through hole 171 and is screwed into the internal threaded hole 181 to fix the sound-producing body 110 and the connecting body 120 together. See the attached diagram for another example. Figure 8 The fastener 190 is a bolt 191, and the audio module 100 also includes a nut 192 that mates with the bolt 191. The mounting part 170 has a second through hole 172, and the mating part 180 has a third through hole 182 that corresponds one-to-one with the second through hole 172. The fastener 190 passes through the second through hole 172 and the third through hole 182 and is screwed into the nut 192 to fix the speaker body 110 and the connecting body 120 together. Thus, unlike methods such as magnetic fixation using the fastener 190, the screwed connection between the fastener 190 and the internal threaded hole 181 or the fastener 190 and the bolt 191 provides a stronger and more stable connection, improving the connection strength and stability between the mounting part 170 and the mating part 180. Furthermore, the above embodiments can be selected according to different production scenarios, and are not limited in detail here.

[0092] It should be noted that the shape of the sound-producing body 110 can be blocky or irregular, and no further limitation is made here.

[0093] In conjunction with any embodiment of the sound-producing body 110 described above, in some embodiments, see Appendix Figure 5, the pronunciation body 110 includes a first body 113 and a second body 114, and the first body 113 protrudes 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 by arranging the first body 113 to protrude from the second body 114, a "convex" shape is formed between the first body 113 and the second body 114. 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. Further, 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. Different from processing the mounting portion 170 on the first body 113, it can reduce the processing difficulty and avoid causing 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 portions 170 and the matching portions 180 can be one group or multiple groups, and no excessive limitation is made here.

[0095] Combined with any embodiment of the above-mentioned mounting portion 170 and the matching portion 180, in some embodiments, refer to the appendix Figure 6 , at least three mounting portions 170 are arranged on the second body 114 at intervals, at least three matching portions 180 are arranged on the connecting body 120 at intervals, and the mounting portions 170 and the matching portions 180 are fixedly connected in one-to-one correspondence to fixedly connect the pronunciation body 110 and the connecting body 120. It can be understood that at least three mounting portions 170 are arranged on the second body 114 at intervals, so that at least three mounting portions 170 form at least one mounting surface on the second body 114, that is, there is 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 one example, refer to the appendix Figure 6 , the first body 113 is distributed in a square shape, at least four mounting portions 170 are arranged on the second body 114 at intervals, and are respectively distributed around the four sides of the first body 113. In another example, refer to the appendix Figure 7 , the first body 113 is distributed in a square shape, at least four mounting portions 170 are arranged on the second body 114 at intervals, and are arranged close to the four corners of the first body 113.
