Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of electro-acoustic products, in particular to a loudspeaker module and electronic equipment. BACKGROUND

[0002] The current conventional loudspeaker is usually provided with a single moving coil sound unit, but the single moving coil sound unit cannot effectively consider the performance of low frequency and medium-high frequency, so it is necessary to combine the advantages of the moving coil sound unit and the moving iron sound unit, so that the loudspeaker module has higher high frequency extension and lower low frequency diving ability.

[0003] The inventor finds that the current loudspeaker module combining the moving coil sound unit and the moving iron sound unit has the following problems: since the current loudspeaker module is integrated with the moving coil sound unit and the moving iron sound unit by using a flexible circuit board, the flexible circuit board needs to be additionally added on the basis of the original loudspeaker structure, which increases the production cost. In addition, the flexible circuit board is relatively soft, and the fixing effect of the moving coil sound unit and the moving iron sound unit is not good. SUMMARY

[0004] The purpose of the embodiment of the present application is to provide a loudspeaker module and electronic equipment, by improving the original fixing structure of the moving coil sound unit, so that the moving coil sound unit and the moving iron sound unit can be integrated, which facilitates the installation of the moving coil sound unit and the moving iron sound unit, and reduces the assembly cost.

[0005] In order to solve the above technical problems, the embodiment of the present application provides a loudspeaker module, which comprises: a moving coil sound unit, a moving iron sound unit and a basket; the basket comprises: a first accommodating part for mounting the moving coil sound unit, and a second accommodating part for mounting the moving iron sound unit; the basket further comprises: a first sound outlet communicated with the first accommodating part, and a second sound outlet communicated with the second accommodating part, and the first sound outlet and the second sound outlet are located at the same side of the loudspeaker module.

[0006] The embodiment of the present application further provides electronic equipment, which comprises: a shell and the above-mentioned loudspeaker module arranged in the shell.

[0007] Compared to existing technologies, this invention improves the original frame structure for fixing the dynamic driver unit. It includes both a first housing for the dynamic driver unit and a second housing for the balanced armature driver unit. A first sound outlet is connected to the first housing, and a second sound outlet is connected to the second housing. The first and second sound outlets are located on the same side of the speaker module. Therefore, the sounds emitted by the dynamic and balanced armature drivers can be better integrated, enhancing the acoustic quality of the speaker module. Furthermore, this invention improves upon the original frame structure, providing fixed housings for both the dynamic and balanced armature drivers, facilitating their installation and reducing assembly costs.

[0008] In addition, the speaker module also includes a cover; the cover and the frame form a cavity, and the dynamic driver and the balanced armature driver are completely housed inside the cavity. The sounds of the dynamic driver and the balanced armature driver can blend naturally inside the cavity, improving the acoustic quality of the speaker.

[0009] In addition, the cavity is filled with mesh or sound-absorbing cotton, which can further improve the acoustic quality.

[0010] In addition, the frame also includes a sound outlet duct; the sound outlet duct is connected to both the first and second sound outlets. This allows the sound from the dynamic driver unit to be guided through the sound outlet duct to the sound output position of the balanced armature driver unit, promoting natural sound integration.

[0011] In addition, the balanced armature driver includes a top cover, a sound-emitting element, and a bottom cover. The sound-emitting element is housed within the space formed by the top and bottom covers, and the top cover has an opening whose position corresponds to the position of the second sound outlet. This opening position can improve the sound utilization rate of the balanced armature driver.

[0012] In addition, the first and second sound outlets are located on the side of the speaker module closest to the balanced armature driver. This design improves the quality of high-frequency sound.

[0013] In addition, the shapes of the first and second sound outlets are: circular, oval, or rectangular.

[0014] In addition, the electronic device also includes: a device sound outlet; the distance between the second sound outlet of the speaker module and the device sound outlet is closer than the distance between the first sound outlet of the speaker module and the device sound outlet. This design can improve the quality of high-frequency sound. Attached Figure Description

[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings. However, those skilled in the art can understand that in the embodiments of the present application, many technical details are proposed in order to make the readers better understand the present application. However, the technical scheme claimed by the present application can be realized even without these technical details and various changes and modifications based on the following embodiments.

[0033] The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation of the present application, and the embodiments can be combined and referenced with each other under the premise of no contradiction.

[0034] The embodiments of the present application relate to a loudspeaker module, as shown in Figures 1-2 the first accommodating part for mounting the moving coil sound unit, and the second accommodating part for mounting the moving iron sound unit; the basket 1 further comprises the first sound outlet communicated with the first accommodating part, and the second sound outlet communicated with the second accommodating part, and the first sound outlet and the second sound outlet are located at the same side of the loudspeaker module.

[0035] The embodiments of the present application improve the basket structure originally fixed with the moving coil sound unit, so that the basket structure contains the first accommodating part for mounting the moving coil sound unit and the second accommodating part for mounting the moving iron sound unit, the first sound outlet is arranged in communication with the first accommodating part, and the second sound outlet is arranged in communication with the second accommodating part, and the first sound outlet and the second sound outlet are located at the same side of the loudspeaker module. Therefore, the sound emitted by the moving coil sound unit and the moving iron sound unit can be better fused, and the acoustic quality of the loudspeaker module is strengthened. In addition, the present application is an improvement on the basis of the original basket structure, and the improved basket structure has fixed accommodating parts for mounting the moving coil sound unit and the moving iron sound unit, which facilitates the installation of the moving coil sound unit and the moving iron sound unit, and reduces the assembly cost.

[0036] In addition, as shown in Figure 1 the cover body and the basket 1 form a cavity, and the moving coil sound unit 2 and the moving iron sound unit 3 are completely accommodated in the cavity. The sound of the moving coil sound unit 2 and the moving iron sound unit 3 can be naturally integrated in the cavity, improving the acoustic quality of the loudspeaker. The cavity is filled with gauze or sound-absorbing cotton to further improve the acoustic quality, and the cavity also includes acoustic impedance material to suppress external environmental noise.

[0037] In addition, the basket 1 further comprises: an audio output pipeline; the audio output pipeline is in communication with the first audio output port and the second audio output port. In this way, the sound of the moving coil sound unit can be guided to the audio output position of the moving iron sound unit through the audio output pipeline, promoting the natural integration of the sound. The shapes of the first audio output port and the second audio output port can be customized, for example, designed as a circle, an ellipse or a rectangle, and the mold can be opened according to the actual use requirements.

[0038] In addition, the cover body comprises an upper cover body 41 and a lower cover body 42, and in actual design, the upper cover body 41 structure can be omitted, as shown in Figure 2 part of the moving coil sound unit 2 and the moving iron sound unit 3 are exposed, and when the upper cover body 41 structure is omitted, the first audio output port and the second audio output port need to be arranged on one side of the lower cover body 42. If the moving coil sound unit 2 and the moving iron sound unit 3 are completely accommodated in the cavity by using the upper cover body 41, the first audio output port and the second audio output port can be arranged on one side of the upper cover body 41 or arranged on the side close to the position of the moving iron sound unit 3. Arranging the audio output port on the side close to the moving iron sound unit 3 can ensure the low-frequency sound quality and improve the high-frequency sound quality, because the moving iron sound unit 3 has better high-frequency sound quality.

[0039] In addition, the second audio output port is arranged opposite to the opening position of the moving iron sound unit, which can also avoid the loss of high-frequency sound in the transmission process and improve the high-frequency sound quality.

[0040] The embodiment of the present application also relates to the structure of the moving coil sound unit 2 and the structure of the moving iron sound unit 3, as shown in Figure 3As shown, the moving-coil sound unit 2 consists of a magnetic cup 21, a first magnet 22, a magnetic sheet 23, a first coil 24, and a first diaphragm 25. The first magnet 22 experiences a force in the magnetic field. A changing current passes through the first coil 24, generating a changing magnetic field, which causes the first diaphragm 25 to vibrate, producing sound. The first coil 24 is placed in the air gap of the magnetic circuit system (magnetic sheet, first magnet, magnetic cup). The first coil 24 connects to the first diaphragm 25, causing it to vibrate and radiate sound waves. The outer side of the first diaphragm 25 is fixed to the integrated frame 1. One side of the frame is connected to the lower cover 42, and the other side is connected to the upper cover 41. The structure of the moving-iron sound unit 3 is as follows... Figure 4 As shown, the structure includes: an upper cover 31, a lower cover 32, a second diaphragm 33, a magnetic ring 34, a second coil 35, an armature 36, a second magnet 37, and a connecting rod 38. The armature 36 vibrates in the air gap of the magnetic circuit system (magnetic ring, second coil, second magnet), driving the second diaphragm 33 to vibrate and radiate sound waves through the connecting rod. The upper cover 31 and lower cover 32 house the remaining components (sound-producing elements) within their combined accommodating space, and the upper cover 31 has an opening whose position corresponds to the second sound outlet. Depending on the position of the second sound outlet, the opening can be selected to be located in the middle or at the edge of the upper cover 31.

[0041] The following describes the structures of several specific speaker modules:

[0042] like Figures 5-6 As shown, this is a side-emitting speaker module. The moving-iron driver unit 3 is located on the side of the frame 1 and is placed horizontally within the frame 1. The moving-coil driver unit 2 and the moving-iron driver unit 3 are sealed together by the upper cover 41 to form a combined acoustic cavity. Meanwhile, according to... Figure 6 The solid line represents the direction of sound propagation of the moving coil sound unit, and the dashed line represents the direction of sound propagation of the moving iron sound unit. The first sound outlet 11 and the second sound outlet 12 are located at the same position, both on one side of the moving iron sound unit. The sound emitted by the moving coil sound unit 2 and the moving iron sound unit 3 is blended and then transmitted through the first sound outlet and the second sound outlet.

[0043] like Figures 7-8 As shown, another type of speaker module is used, in which the moving iron sound unit 3 is located on the side of the frame 1 and is placed horizontally in the frame 1. The moving coil sound unit 2 and the moving iron sound unit 3 are covered by the upper cover 41, but several first sound outlets 11 and several second sound outlets 12 are evenly arranged on the upper cover 41. Figure 8The direction of sound propagation is marked. The solid line represents the direction of sound propagation of the moving coil sound unit, and the dashed line represents the direction of sound propagation of the balanced armature sound unit. The first sound outlet 11 and the second sound outlet 12 are set in different positions. Therefore, the sound of the moving coil sound unit 2 and the balanced armature sound unit 3 is transmitted out of the speaker module through different sound outlets. In order to blend the sound emitted by the moving coil sound unit 2 and the balanced armature sound unit 3, a cavity can be formed above the upper cover 41 to blend the sound. The blended sound is then transmitted out through the device sound outlet of the electronic device.

[0044] like Figures 9-10 As shown, this is another type of speaker module with side-emitting sound. The moving iron driver unit 3 is located on the side of the frame 1, and is placed vertically in the frame 1. The top cover of the moving iron driver unit is close to the frame 1. The top cover 41 seals the moving coil driver unit 2 and the moving iron driver unit 3 to form a combined acoustic cavity. Meanwhile, according to... Figure 10 The solid line represents the direction of sound propagation of the moving coil sound unit, and the dashed line represents the direction of sound propagation of the moving iron sound unit. The first sound outlet 11 and the second sound outlet 12 are located at the same position, both on one side of the moving iron sound unit. The sound emitted by the moving coil sound unit 2 and the moving iron sound unit 3 is blended and then transmitted through the first sound outlet and the second sound outlet.

[0045] like Figures 11-12 As shown, this is a front-firing speaker module. The balanced armature driver unit 3 is located on the side of the frame 1 and stands upright in the frame 1. The top cover of the balanced armature driver unit is close to the moving coil driver unit 2. Since sound propagates at the bottom cover, the top cover is omitted. Figure 12 The solid line represents the direction of sound propagation of the dynamic driver unit, and the dashed line represents the direction of sound propagation of the balanced armature driver unit. The first and second sound outlets are located in different positions, but in order to facilitate sound fusion, the positions of the first and second sound outlets are set as close as possible. A cavity is formed below the lower cover 42 to cover the first and second sound outlets to fuse the sound. The fused sound is then transmitted from the device's sound outlet.

[0046] like Figures 13-14 As shown, this is another type of front-firing speaker module. The balanced armature driver unit 3 is located on the side of the frame 1, and is placed vertically within the frame 1. The top cover of the balanced armature driver unit is close to the moving coil driver unit 2. Since sound propagates at the bottom cover, the top cover is omitted. Figure 14The solid line represents the direction of sound propagation of the dynamic driver unit, and the dashed line represents the direction of sound propagation of the balanced armature driver unit. The first and second sound outlets are located in different positions, but in order to facilitate sound fusion, the positions of the first and second sound outlets are set as close as possible. A cavity is formed below the lower cover 42 to cover the first and second sound outlets to fuse the sound. The fused sound is then transmitted from the device's sound outlet.

[0047] like Figures 15-16 As shown, this is another type of front-firing speaker module. The balanced armature driver unit 3 is located on the side of the frame 1, and is placed horizontally within the frame 1. The top cover of the balanced armature driver unit is close to the moving coil driver unit 2. Since sound propagates at the bottom cover, the top cover is omitted. Figure 16 The solid line represents the direction of sound propagation of the dynamic driver unit, and the dashed line represents the direction of sound propagation of the balanced armature driver unit. The first and second sound outlets are located in different positions, but in order to facilitate sound fusion, the positions of the first and second sound outlets are set as close as possible. A cavity is formed below the lower cover 42 to cover the first and second sound outlets to fuse the sound. The fused sound is then transmitted from the device's sound outlet.

[0048] Embodiments of the present invention also relate to an electronic device, including: a housing and the aforementioned speaker module disposed within the housing. The electronic device further includes: a device sound outlet; the distance between the second sound outlet of the speaker module and the device sound outlet is closer than the distance between the first sound outlet of the speaker module and the device sound outlet. This design can improve the quality of high-frequency sound.

[0049] In addition, if the first and second sound outlets are located in different positions, a cavity can be set up near the first and second sound outlets to accommodate them. The sound emitted by the first and second sound outlets is mixed in the cavity and emitted by the device's sound outlet, providing a mixing environment for the speaker module to improve the sound playback effect.

[0050] In addition, electronic devices include, but are not limited to, full-range sound-producing devices such as headphones and speakers.

[0051] The speaker module in this embodiment is consistent with the implementation details in the previous speaker module embodiment. The relevant technical details mentioned in the speaker module embodiment are still valid in this embodiment. In order to reduce repetition, they will not be repeated here.

[0052] Those skilled in the art can understand that the above-mentioned embodiments are specific embodiments for implementing the present application, and various changes can be made in form and details in practical application without departing from the spirit and scope of the present application.
