[0057] Figure 1Schematic diagram of the structure of the speaker of this embodiment. Figure 2 and Figure 3 2 is an exploded schematic diagram of the loudspeaker of this embodiment. The loudspeaker in the figure comprises two paired component units 1, and a common magnetic portion 24 is arranged between the two component units 1.

[0058] Figure 4 1 is a schematic diagram of the structure of the component unit 1 and the magnetic assembly 2 of this embodiment. The dotted line in the figure shows a portion of the second magnetic conductive plate 112 located inside the frame 12. Figure 5 yes Figure 1 The left side of the figure shows the first sound unit, and the right side shows the second sound unit.

[0059] In some embodiments, Figure 1-Figure 2 As shown, the speaker in this embodiment includes two component units 1 and a magnetic component 2. The two component units 1 are configured to be able to be assembled together.

[0060] Further reference Figure 3-Figure 4 As shown, the magnetic assembly 2 includes a first central magnetic portion 21 and a second central magnetic portion 22. The two component units 1 are arranged in pairs and correspond to the first central magnetic portion 21 and the second central magnetic portion 22, respectively.

[0061] The component unit 1 includes a diaphragm 13, a magnetic conductive member 11 and a frame 12. The magnetic conductive member 11 includes a first magnetic conductive plate 111 and a second magnetic conductive plate 112, and the second magnetic conductive plate 112 and the diaphragm 13 are fixedly connected to the frame 12. When two component units 1 are assembled together, the two diaphragms 13 face opposite directions and are at least partially staggered.

[0062] Specifically, the magnetic conductive member 11 in this embodiment is used to guide the magnetic force of the first central magnetic portion 21 and the second central magnetic portion 22. The magnetic conductive member 11 may be made of a material with high magnetic permeability, such as carbon steel.

[0063] Further reference Figure 5As shown, in this embodiment, the first central magnetic portion 21 and the second central magnetic portion 22 are respectively attracted to the two first magnetic conductive plates 111. The magnetic force of the first central magnetic portion 21 acts on the second central magnetic portion 22 through the corresponding second magnetic conductive plate 112 to form at least part of the first magnetic gap 31. That is, the magnetic force of the first central magnetic portion 21 is transmitted to the second central magnetic portion 22 through the first magnetic conductive plate 111 and the second magnetic conductive plate 112 respectively. The magnetic force of the second central magnetic portion 22 acts on the first central magnetic portion 21 through the corresponding second magnetic conductive plate 112 to form at least part of the second magnetic gap 32. That is, the magnetic force of the second central magnetic portion 22 is transmitted to the first central magnetic portion 21 through the first magnetic conductive plate 111 and the second magnetic conductive plate 112 respectively. The material of the first central magnetic portion 21 and the second central magnetic portion 22 in this embodiment may include ferrite to provide stable magnetic force to the first central magnetic portion 21 and the second central magnetic portion 22.

[0064] Specifically, Figure 5 As shown, the two magnetic conductive parts 11, the first central magnetic part 21 and the second central magnetic part 22 in this embodiment constitute a magnetic circuit system. In the figure, the N pole of the first central magnetic part 21 is arranged close to the first magnetic conductive plate 111, and the S pole of the second central magnetic part 22 is arranged close to the first magnetic conductive plate 111. In this form, in the first sound-emitting unit, the first central magnetic part 21 provides magnetic force to the inner wall of the first magnetic gap 31 and the outer wall of the second magnetic gap 32 at the same time. In the second sound-emitting unit, the second central magnetic part 22 provides magnetic force to the inner wall of the second magnetic gap 32 and the outer wall of the first magnetic gap 31 at the same time. As a result, the number of internal parts of the speaker is reduced, which helps to reduce the weight of the speaker.

[0065] In summary, in the speaker of this embodiment, the second magnetic conductive plate 112 and the diaphragm 13 are arranged on the frame 12 to form two component units 1 arranged in pairs. When the two component units 1 are assembled, the two diaphragms 13 face opposite directions and staggered to improve the sound quality of the speaker and reduce the vibration amplitude of the speaker. Thus, on the one hand, the first central magnetic part 21 and the second central magnetic part 22 are respectively attracted together with the corresponding first magnetic conductive plate 111, and the magnetic force generated by the first central magnetic part 21 and the second central magnetic part 22 is used to act on the second central magnetic part 22 and the first central magnetic part 21 through the two first magnetic conductive plates 111 to form the first magnetic gap 31 and the second magnetic gap 32. Thus, the structure of the magnetic circuit system of the speaker is simplified, which helps to reduce the overall weight of the speaker and reduce the volume occupied. On the other hand, the volume of the sound cavity 115 of the speaker can be further increased to improve the sound quality of the speaker.

[0066] Figure 6 Schematic diagram of the explosion of the component unit 1 and the side magnetic part 23 of this embodiment. Figure 7 Schematic diagram of the structure of the component unit 1 and the side magnetic part 23 of this embodiment.

[0067] In some embodiments, Figure 5-Figure 7 As shown, the first magnetic conductive plate 111 of one component unit 1 is arranged opposite to and spaced from the second magnetic conductive plate 112 of another component unit 1. That is, the frame 12 is arranged corresponding to the first magnetic conductive plate 111.

[0068] The magnetic assembly 2 further includes two side magnetic portions 23. The two side magnetic portions 23 correspond to the first central magnetic portion 21 and the second central magnetic portion 22 respectively. The side magnetic portions 23 are sandwiched between the first magnetic conductive plate 111 and the second magnetic conductive plate 112 respectively located in the two component units 1. That is, the side magnetic portions 23 are attracted between the first magnetic conductive plate 111 and the second magnetic conductive plate 112.

[0069] At the same time, further reference Figure 5 As shown, the magnetic force of one side magnetic portion 23 (the side magnetic portion 23 corresponding to the second central magnetic portion 22) acts on the first central magnetic portion 21 through the second magnetic conductive plate 112 on one side, and acts on the second central magnetic portion 22 through the first magnetic conductive plate 111 on the other side. The magnetic force of another side magnetic portion 23 (the side magnetic portion 23 corresponding to the first central magnetic portion 21) acts on the second central magnetic portion 22 through the second magnetic conductive plate 112 on one side, and acts on the first central magnetic portion 21 through the first magnetic conductive plate 111 on the other side.

[0070] The side magnetic portion 23 corresponding to the first central magnetic portion 21 in this embodiment is used to cooperate with the second central magnetic portion 22 to increase the magnetic field strength in the first magnetic gap 31. In contrast, the side magnetic portion 23 corresponding to the second central magnetic portion 22 is used to cooperate with the first central magnetic portion 21 to increase the magnetic field strength in the second magnetic gap 32.

[0071] Specifically, Figure 5 As shown, in this embodiment, the side magnetic part 23 is a magnet, and the polarity of the two side magnetic parts 23 is opposite to the polarity of the first central magnetic part 21 and the second central magnetic part 22. In the first sound-emitting unit, the magnetic field of the first central magnetic part 21 can be transferred from the N pole to the S pole of the side magnetic part 23 through the first magnetic conductive plate 111, and the magnetic field generated by the side magnetic part 23 can be transferred from the N pole to the S pole of the second central magnetic part 22 through the second magnetic conductive plate 112 and the first magnetic conductive plate 111 (the magnetic field distribution of the second sound-emitting unit is similar to that of the first sound-emitting unit). Thus, the side magnetic part 23 can cooperate with the first central magnetic part 21 and the second central magnetic part 22 to increase the magnetic flux in the first magnetic gap 31 and the second magnetic gap 32.

[0072] Figure 8 , Fig. 9 and Fig.10 It is a schematic structural diagram of the component unit 1 of this embodiment. Fig.10 The outline of the middle frame 12 is shown with a dotted line, and the outline of the magnetic conductive member 11 is shown with a thick solid line. Fig.11 It is an exploded schematic diagram of the component unit 1 of this embodiment.

[0073] In some embodiments, Figure 6 As shown, the frame 12 has a receiving window 121. Figure 8-Figure 11 As shown, the second magnetic conductive plate 112 includes a first plate body 113 that is attracted to the side magnetic portion 23. The first plate body 113 extends from the edge of the accommodating window 121 to form a first magnetic gap 31 with the first central magnetic portion 21, or a second magnetic gap 32 with the second central magnetic portion 22.

[0074] Specifically, in this embodiment, the number of the first plates 113 is two, and the two first plates 113 correspond to the first central magnetic portion 21 and the second central magnetic portion 22, respectively, and the length of the first plate 113 is adapted to the length of the side magnetic portion 23. At the same time, the edge of the first plate 113 is closer to the first central magnetic portion 21 or the second central magnetic portion 22, which helps the magnetism of the side magnetic portion 23 to act on the first central magnetic portion 21 or the second central magnetic portion 22 through the first plate 113.

[0075] In some embodiments, Figure 5-Figure 6 As shown, the frame 12 also has a first positioning surface 122 and a first positioning groove 123. The first positioning surface 122 and the first positioning groove 123 are both facing the first magnetic conductive plate 111. That is, the first positioning surface 122 is arranged on the side of the frame 12 away from the diaphragm 13, and the first positioning groove 123 is provided on the first positioning surface 122.

[0076] In this embodiment, the first positioning surface 122 and the first magnetic conductive plate 111 abut against each other, and can be used to position the two component units 1 when the two component units 1 are assembled. For example, an adhesive is used to bond the second positioning surface 125 and the first magnetic conductive plate 111 together. In this form, the side magnetic portion 23 is clamped in the first positioning groove 123 and is attracted to the second magnetic conductive plate 112. This ensures that the magnetic force of the side magnetic portion 23 can directly act on the second magnetic conductive plate 112.

[0077] In some embodiments, Figure 6-Figure 7 As shown, the frame 12 includes a side beam 124. The frame 12 is an injection molded part, a portion of the second magnetic conductive plate 112 is disposed inside the side beam 124, and a side of the first plate 113 facing the side magnetic portion 23 is exposed outside the side beam 124.

[0078] Specifically, the first plate body 113 in this embodiment has a first contact surface. During the injection molding process of the frame 12, the first plate body 113 is arranged on the inner side of the frame 12, and the first plate body 113 is located at the position of the side beam 124 to expose the first contact surface on the outside of the side beam 124. In this form, the first contact surface is located at the bottom of the first positioning groove 123. When the side magnetic part 23 is clamped in the first positioning groove 123, the side magnetic part 23 can just contact with the first contact surface and be attracted together. Thereby, the assembly process of the speaker is simplified.

[0079] In some embodiments, Fig.11 As shown, the second magnetic conductive plate 112 also includes a second plate body 114. The second plates 114 of the two component units 1 are arranged opposite to each other. The second plate body 114 includes a second contact surface. The second plate body 114 can also be arranged inside the frame 12 during the injection molding process of the frame 12, and the second contact surface is exposed to the outside of the frame 12, and the edge of the second plate body 114 close to the first plate body 113 extends into the accommodating window 121. The second plate body 114 can cooperate with the first central magnetic part 21 or the second central magnetic part 22 to form a magnetic gap.

[0080] Further reference Figure 2-Figure 4 As shown, the magnetic assembly 2 further includes a common magnetic portion 24. The common magnetic portion 24 is disposed between the first central magnetic portion 21 and the second central magnetic portion 22 at intervals.

[0081] The common magnetic part 24 is attracted between the two second plates 114, that is, the top of the common magnetic part 24 is attracted to one second plate 114, and the bottom of the common magnetic part 24 is attracted to the other second plate 114. The magnetic force of the common magnetic part 24 acts on the first central magnetic part 21 and the second central magnetic part 22 through the two second plates 114, respectively, to form the first magnetic gap 31 or the second magnetic gap 32.

[0082] Figure 5 A specific configuration of the magnetic circuit system is shown in FIG. In the figure, the polarities of the two side magnetic parts 23 and the common magnetic part 24 are the same, that is, the S poles of the side magnetic parts 23 and the common magnetic part 24 are all facing the same side of the speaker, and the S poles of the side magnetic parts 23 and the common magnetic part 24 are opposite to the S poles of the first central magnetic part 21 and the second central magnetic part 22.

[0083] In this form, the common magnetic part 24 located in the middle can provide magnetic force for the first sound unit and the second sound unit at the same time, thereby making the structure of the magnetic circuit system more compact, with fewer parts and lighter weight.

[0084] In some embodiments, Figure 6As shown, the frame 12 also has a second positioning surface 125 and a second positioning groove 126. Figure 5 and Figure 7 As shown, when the two components 1 are in the assembled state, the two second positioning surfaces 125 of the two components 1 are in contact with each other, and the two second positioning grooves 126 are buckled to form a positioning window 127. At the same time, the common magnetic portion 24 is locked in the positioning window 127.

[0085] The two second positioning surfaces 125 in this embodiment are used to cooperate with the second positioning grooves 126 to form a positioning window 127. The positioning window 127 is located between the first sound unit and the second sound unit. The positioning window 127 can stably clamp the common magnetic part 24 between the two component units 1, and keep the common magnetic part 24 and the two second plates 114 stably attached together.

[0086] In some embodiments, Figure 1 and Figure 5 As shown, the first magnetic conductive plate 111 of one component unit 1 is arranged opposite to and spaced from the second magnetic conductive plate 112 of another component unit 1. The magnetic assembly 2 also includes two side magnetic portions 23. The first central magnetic portion 21 and the second central magnetic portion 22 are located between the two side magnetic portions 23. The side magnetic portion 23 is attracted between the first magnetic conductive plate 111 and the second magnetic conductive plate 112.

[0087] Further reference Figure 6-Figure 7 As shown, a receiving cavity is formed between the two side magnetic parts 23 and the two component units 1. That is, the receiving cavity is formed by surrounding the two magnetic conductive parts 11, the two frames 12 and the two diaphragms 13. At the same time, the common magnetic part 24 in this embodiment is arranged in the positioning window 127 to separate the receiving cavity to form two sound cavities 115.

[0088] Thus, the common magnetic part 24 in this embodiment is arranged between the two sound-emitting units, so that the speaker can have two relatively independent sound chambers 115. The two sound chambers 115 are arranged horizontally in the length direction of the speaker to reduce the thickness of the speaker. At the same time, the volume of the sound chamber 115 can be further increased, thereby improving the sound quality of the speaker.

[0089] In some embodiments, Figure 3 and Figure 5As shown, the first central magnetic portion 21 and the second central magnetic portion 22 both include a first magnetic body 25 and a third magnetic conductive plate 26. The first magnetic body 25 is attracted between the first magnetic conductive plate 111 and the third magnetic conductive plate 26, and the third magnetic conductive plate 26 is arranged corresponding to the second magnetic conductive plate 112. The third magnetic conductive plate 26 in this embodiment is used to guide the magnetic force of the first magnetic body 25, so that the magnetic force acts on the second magnetic conductive plate 112 to form a magnetic gap. By using the cooperation of the third magnetic conductive plate 26 with the first plate body 113 and the second plate body 114, the distribution of magnetic lines of force in the first magnetic gap 31 or the second magnetic gap 32 can be made more uniform. When the voice coil 4 moves in the first magnetic gap 31 or the second magnetic gap 32, the Ampere force it receives can also be more stable, thereby being able to drive the diaphragm 13 to vibrate stably.

[0090] In an optional implementation, the speaker in the above embodiment may be applied to an electronic device, including but not limited to a mobile phone, a laptop computer, or a smart watch.

[0091] The electronic device in this embodiment includes a speaker, and the second magnetic conductive plate 112 and the diaphragm 13 in the speaker are arranged on the frame 12 to form two component units 1 arranged in pairs. When the two component units 1 are assembled, the two diaphragms 13 face opposite directions and staggered to improve the sound quality of the speaker and reduce the vibration amplitude of the speaker. Thus, on the one hand, the first central magnetic part 21 and the second central magnetic part 22 are respectively attracted together with the corresponding first magnetic conductive plate 111, and the magnetic force generated by the first central magnetic part 21 and the second central magnetic part 22 is used to act on the second central magnetic part 22 and the first central magnetic part 21 through the two first magnetic conductive plates 111 to form a first magnetic gap 31 and a second magnetic gap 32. Thus, the magnetic circuit system structure of the speaker is simplified, which helps to reduce the overall weight of the speaker and reduce the volume occupied. On the other hand, the volume of the sound cavity 115 of the speaker can be further increased to improve the sound quality of the electronic device.

[0092] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
