Description

Speaker units and electronic equipment Technical Field

[0001] The present invention relates to the field of sound-to-electricity conversion, and in particular to a loudspeaker unit and electronic equipment. Background Art

[0002] Speakers are a crucial component widely used in various portable electronic devices, including mobile phones, tablets, and portable game consoles. In a traditional speaker unit, the vibration system consists of a voice coil and a diaphragm assembly, which are secured together with glue. This allows the voice coil to drive the diaphragm assembly to vibrate and produce sound.

[0003] However, traditional speaker units often do not have a wire routing structure for the voice coil wire. The voice coil wire is often directly clamped between the voice coil and the diaphragm assembly, which requires a larger space to be reserved between the voice coil as a whole and the diaphragm assembly in the vibration direction of the diaphragm assembly to set the voice coil wire. As a result, the overall size of the speaker unit becomes larger, and it is easy to affect the bonding effect between the voice coil and the diaphragm assembly, resulting in weak reliability.

[0004] Therefore, it is necessary to design a new type of loudspeaker to change the current situation. Summary of the Invention

[0005] In order to solve the problem that the existing technology has a relatively large overall size and poor reliability, the present invention provides a speaker unit and an electronic device that are conducive to miniaturization design and have better reliability.

[0006] To achieve the above-mentioned purpose, the present invention provides a speaker unit, including a basin frame with a receiving space and a magnetic circuit system and a vibration system accommodated in the receiving space, the vibration system including a voice coil and a diaphragm assembly, the voice coil including a main body and a wire leading out from the main body, the diaphragm assembly including a main body and a avoidance portion formed by bending from the main body in a direction away from the voice coil, the main body being bonded to the main body and forming an avoidance space with the avoidance portion, and the avoidance space is used for the wire to pass through to connect to an external power supply component.

The wire includes a first end line and a second end line, and the first end line and the second end line pass through the two avoidance spaces respectively; wherein, one of the first end line and the second end line is used to connect to the positive pole of the external power supply component, and the other is used to connect to the negative pole of the external power supply component.

[0008] As an improvement, the two avoidance portions are symmetrically arranged with the center point of the main body as the center of symmetry.

[0009] As an improvement, the main body includes two oppositely arranged first sides and two second sides connecting the two first sides, and the length of the first side is greater than the length of the second side; the avoidance portion is arranged at the junction of the main body corresponding to the first side and the second side.

[0010] As an improvement, the avoidance portion includes a side wall extending from the main body in a direction away from the voice coil, and an end wall arranged at one end of the side wall away from the voice coil; the orthographic projection of the end wall onto the voice coil falls partially on the inner side of the voice coil and partially on the outer side of the voice coil.

[0011] As an improvement, the area of ​​the orthographic projection of the end wall onto the voice coil that falls on the inner side of the voice coil is larger than the area of ​​the orthographic projection of the end wall onto the voice coil.

[0012] As an improvement, the main body includes a sound membrane fixed to the basin frame and a spherical top connected to the sound membrane, and the avoidance portion is arranged on the spherical top.

[0016] Compared with the related art, the speaker unit and electronic device of the present invention are provided with a diaphragm assembly including a main body and a avoidance portion formed by bending from the main body in a direction away from the voice coil, so that the wire can be connected to the external power supply component through the avoidance portion, thereby making the main body and the voice coil fit better, reducing the gap size between the voice coil as a whole and the main body, thereby realizing the miniaturization of the speaker unit; at the same time, such a design can also reduce the influence of the wire on the bonding effect between the main body and the main body, making the bonding between the main body and the main body more firm and more reliable.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please refer to FIG. 1 to FIG. 5 . An embodiment of the present invention provides a speaker unit 100 . The speaker unit 100 includes a frame 10 having a receiving space 101 , and a magnetic circuit system 20 and a vibration system 30 received in the receiving space 101 .

[0024] The function of the basin frame 10 is to connect and support the magnetic circuit system 20 and the vibration system 30 , so as to provide a stable and sealed working environment for the magnetic circuit system 20 and the vibration system 30 .

[0025] The basin frame 10 has a receiving space 101. A possible implementation method is that the basin frame 10 is a sealed surrounding structure, so that the receiving space 101 is formed by utilizing the surrounding structure. In this case, all components of the magnetic circuit system 20 and the vibration system 30 are received in the receiving space 101. In some embodiments, the basin frame 10 can also be configured as an annular component with openings at both ends. In this case, part of the components of the magnetic circuit system 20 can be used to block the opening at one end of the basin frame 10, and part of the components of the vibration system 30 can be used to block the opening at the other end of the basin frame 10. That is, the basin frame 10, the magnetic circuit system 20, and the vibration system 30 together form the receiving space 101, and the components of the magnetic circuit system 20 for generating electromagnetic induction and the components of the vibration system 30 for inducing electromagnetic vibration are received in the receiving space 101.

[0026] In these embodiments of the present invention, the vibration system 30 includes a voice coil 31 and a diaphragm assembly 32. The voice coil 31 includes a main body 311 and a wire 312 extending from the main body 311. This means that the voice coil 31 is actually a ring-shaped component formed by winding a conductor along a specific path. When energized, it becomes magnetic and vibrates within the magnetic gap of the magnetic circuit system 20. In these embodiments of the present invention, the main body 311 is a ring-shaped structure formed by the conductor, and the wire 312 is the component at the end of the conductor used to connect to an external power supply.

[0027] The diaphragm assembly 32 includes a main body 321 and an avoidance portion 322 bent from the main body 321 in a direction away from the voice coil 31. The main body 321 is a component of the diaphragm assembly 32 used to connect with the voice coil 31 and vibrate and produce sound under the drive of the voice coil 31.

[0028] The avoidance portion 322 is formed by bending from the main body portion 321 in a direction away from the voice coil 31. A possible implementation method is that, during the molding process of the diaphragm assembly 32, the main body portion 321 can be formed into a flat plate first, and then the avoidance portion 322 can be stamped on the main body portion 321 using a stamping process, so that the avoidance portion 322 has a gap structure on one side corresponding to the thickness direction of the main body portion 321, and protrudes from the main body portion 321 on the other side along the thickness direction; in some embodiments, the diaphragm assembly 32 can also be arranged to be molded using an injection molding process, so that the main body portion 321 and the avoidance portion 322 are molded as one piece.

[0029] The main body 311 is bonded to the body 321 and forms the escape space 102 with the escape portion 322. This means that during the bonding process of the main body 311 to the body 321, at least a portion of the main body 311 and the escape portion 322 need to overlap in the vibration direction X of the diaphragm assembly 32. This allows the wire 312 to pass from the inside of the main body 311 to the outside through the escape portion 322, preventing the wire 312 from being sandwiched between the main body 311 and the body 321. This reduces the gap between the main body 311 and the body 321 in the vibration direction X of the diaphragm assembly 32, thereby reducing the volume of the speaker unit 100 and facilitating a miniaturized design of the speaker unit 100.

[0030] In some embodiments of the present invention, two avoidance portions 322 can be set, and the two avoidance portions 322 respectively form the aforementioned avoidance space 102 with the main body 311; the wire 312 includes a first end line 3121 and a second end line 3122, and the first end line 3121 and the second end line 3122 respectively pass through the two avoidance spaces 102; wherein, one of the first end line 3121 and the second end line 3122 is used to connect to the positive pole of the external power supply component, and the other is used to connect to the negative pole of the external power supply component.

[0031] The first end line 3121 and the second end line 3122 are actually line segments at the two ends of the conductor. In these embodiments of the present invention, they can be adapted to different main body 311 structures. That is, when the conductor is wrapped around to form the main body 311, when the distance between the first end line 3121 and the second end line 3122 is relatively close, the first end line 3121 and the second end line 3122 can be set to pass through the same avoidance space 102; and when the distance between the first end line 3121 and the second end line 3122 is relatively far, the first end line 3121 and the second end line 3122 can be set to pass through two avoidance spaces 102 respectively.

[0032] One of the first end line 3121 and the second end line 3122 is used to connect to the positive electrode of the external power supply component, and the other is used to connect to the negative electrode of the external power supply component, so as to form a current path in the main body 311 .

[0033] In some embodiments of the present invention, two avoidance portions 322 may be symmetrically arranged with the center point of the main body 321 as the center of symmetry. The center point of the main body 321 refers to the geometric center of the main body 321. The two avoidance portions 322 are symmetrically arranged with the center point of the main body 321 as the center of symmetry to accommodate the situation where the first end line 3121 and the second end line 3122 are at their farthest distance from each other.

[0034] For example, in some embodiments, the cross-sectional shape of the main body 321 along the vibration direction perpendicular to the diaphragm assembly 32 can be set to be a rectangle. In this case, the two avoidance portions 322 can be respectively set to correspond to the two longer sides of the main body 321, or the two avoidance portions 322 can be respectively set to correspond to the two shorter sides of the main body 321. The present invention does not limit this.

[0035] In some embodiments of the present invention, the main body 311 includes two oppositely arranged first sides 3111 and a second side 3112 connecting the two first sides 3111, and the length of the first side 3111 is greater than the length of the second side 3112. That is, in these embodiments of the present invention, the main body 311 is a rectangular ring structure formed by a conductor, the first side 3111 is the longer side of the rectangular ring structure, and the second side 3112 is the shorter side of the rectangular ring structure.

[0036] The avoidance portion 322 is disposed at the intersection of the first side 3111 and the second side 3112 of the main body 321. That is, in these embodiments of the present invention, the avoidance portion 322 is disposed at a corner of the main body 321 to accommodate the position of the wire 312. At the same time, because the end of the avoidance portion 322 close to the main body 311 is a avoidance structure, the main body 311 and the diaphragm assembly 32 cannot be fixed by gluing at this location, resulting in a low connection strength. This arrangement utilizes the corner structure to provide support for the avoidance portion 322, thereby improving the connection stability between the main body 311 and the main body 321, further enhancing the structural reliability of the speaker unit 100.

[0037] In some embodiments of the present invention, the avoidance portion 322 includes a side wall 3221 extending from the main body 321 in a direction away from the voice coil 31, and an end wall 3222 arranged at one end of the side wall 3221 away from the voice coil 31; the orthographic projection of the end wall 3222 onto the voice coil 31 falls partially on the inner side of the voice coil 31 and partially falls on the outer side of the voice coil 31.

[0038] It should be noted that, in these embodiments of the present invention, the orthographic projection of the end wall 3222 onto the voice coil 31 refers to the projection of the end wall 3222 toward the voice coil 31 along the vibration direction X of the diaphragm assembly 32; the inner side of the voice coil 31 refers to the side of the annular voice coil 31 facing away from the basket 10; and the outer side of the voice coil 31 refers to the side of the annular voice coil 31 close to the basket 10.

[0039] In this way, by setting the end wall 3222 so that its projection onto the voice coil 31 partially falls on the inner side of the voice coil 31 and partially falls on the outer side of the voice coil 31, the avoidance space 102 can connect the space of the voice coil 31 away from the frame 10 and the space close to the frame 10, so that the wire 312 can pass through the avoidance space 102 and connect from the space of the main body 311 away from the frame 10 to the space close to the frame 10.

[0040] In some embodiments of the present invention, the orthographic projection of the end wall 3222 onto the voice coil 31 may be configured so that the area of ​​the end wall 3222 projected onto the inner side of the voice coil 31 is larger than the area of ​​the end wall projected onto the outer side of the voice coil 31. This configuration ensures that the escape space 102 can connect the inner and outer spaces of the voice coil 31 while minimizing the size of the opening connecting the escape space 102 and the outer space of the voice coil 31. This maximizes the sealing performance of the space inside the voice coil 31, reduces the possibility of external dust entering the space inside the voice coil 31, and improves acoustic performance.

[0041] In some embodiments of the present invention, the main body 321 may include a sound membrane 3211 fixed to the basin frame 10 and a spherical top 3212 connected to the sound membrane 3211 , and the avoidance portion 322 is disposed on the spherical top 3212 .

[0042] In these embodiments of the present invention, the sound membrane 3211 is connected to the dome 3212. A possible implementation method is that the sound membrane 3211 and the dome 3212 are an integrated structure, so that the sound membrane 3211 and the dome 3212 can be formed as one piece, so that the sound membrane 3211 and the basin frame 10 can be used to achieve connection, and then the basin frame 10 provides support for the main body 321, and the dome 3212 is connected to the voice coil 31, and vibrates and makes sound under the driving action of the voice coil 31; in some embodiments, the sound membrane 3211 and the dome 3212 can also be set as a split structure, and the sound membrane 3211 and the dome 3212 are formed separately and then bonded with glue.

[0043] In some embodiments, the sound membrane 3211 can be provided to include a ring-shaped folding ring portion 3214, a first end portion 3215 connected to the inner ring of the folding ring portion 3214, and a second end portion 3216 connected to the outer ring of the folding ring portion 3214, at least a portion of the first end portion 3215 overlaps with the dome 3212 in the vibration direction X of the diaphragm assembly 32, and the first end portion 3215 is bonded to the dome 3212.

[0044] In these embodiments of the present invention, the first end 3215 is connected to the second end 3216 through the folding ring portion 3214, wherein the second end 3216 is arranged on the outer ring of the folding ring portion 3214 for connecting to the basin frame 10, and then utilizing the basin frame 10 to provide support for the diaphragm assembly 32; at least a portion of the first end 3215 overlaps with the dome 3212 in the vibration direction X of the diaphragm assembly 32, so that the first end 3215 is used to bond with the dome 3212, and the folding ring portion 3214 is used to reduce the vibration of the dome 3212 in the horizontal direction during the vibration and sound generation process of the diaphragm assembly 32, and support the dome 3212 to vibrate and generate sound in the vertical direction, so as to obtain better acoustic performance.

[0045] In a second aspect, an embodiment of the present invention further provides an electronic device, which includes a speaker unit 100 as provided in any embodiment of the first aspect of the present invention. For example, the electronic device can be, but is not limited to, a mobile phone, a tablet computer, a speaker, a headset, or a display screen.

[0046] The speaker unit 100 and the electronic device of the present invention are provided with a diaphragm assembly 32 including a main body 321 and a avoidance portion 322 formed by bending from the main body 321 in a direction away from the voice coil 31, so that the wire 312 can be connected to the external power supply component through the avoidance portion 322, thereby making the main body 321 and the voice coil 31 better fit, reducing the gap size between the voice coil 31 as a whole and the main body 321, thereby realizing the miniaturization of the speaker unit 100; at the same time, such a design can also reduce the influence of the wire 312 on the bonding effect between the main body 321 and the main body 311, making the bonding between the main body 321 and the main body 311 more firm and more reliable.

[0047] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
