[0059] In view of the above problems existing in the prior art, the utility model provides a loudspeaker module and electronic equipment, the loudspeaker module includes first shell, second shell and loudspeaker part. First shell is used for connecting with electronic equipment, and the first shell is a flexible piece. Second shell is connected with the first shell, and the first shell and the second shell form an installation cavity. The loudspeaker part is arranged in the installation cavity and is connected with the second shell. The first shell is a flexible piece, and when the loudspeaker part vibrates, the first shell can deform within a certain range, thereby effectively blocking the transmission resonance caused by the vibration of the loudspeaker part and avoiding resonance noise, so as to improve the sound quality of the electronic equipment.

[0060] Next, the exemplary application scenarios of the utility model are introduced.

[0061] The loudspeaker module provided by the utility model can be applied to electronic equipment, such as a notebook computer, a tablet computer, a smart phone and the like. Specifically, the loudspeaker module provided by the utility model can effectively block the transmission resonance caused by the vibration of the loudspeaker part and avoid resonance noise, so as to improve the sound quality of the electronic equipment.

[0062] The technical solutions of the application and how the technical solutions of the application solve the above problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the application will be described below with reference to the drawings.

[0063] Referring to Figures 3 to 5 The loudspeaker module 10 provided by the embodiments of the application includes a first shell 100, a second shell 200 and a loudspeaker part 300.

[0064] The first shell 100 is used for connecting with the electronic equipment 20, and the first shell 100 is a flexible piece.

[0065] The second shell 200 is connected with the first shell 100, and the first shell 100 and the second shell 200 form an installation cavity 210.

[0066] The loudspeaker part 300 is arranged in the installation cavity 210 and is connected with the second shell 200.

[0067] It can be understood that the loudspeaker module 10 provided by the embodiments of the application can be applied to the electronic equipment 20, such as a notebook computer, a tablet computer, a smart phone and the like, and the notebook computer is taken as an example for exemplary description.

[0068] Referring to Figures 3 to 5As shown, the notebook computer has a C shell 40 and a D shell 50, the first shell 100 of the speaker module 10 can be connected with the C shell 40, the speaker unit 300 is arranged in the mounting cavity 210 formed by the first shell 100 and the second shell 200, and the speaker unit 300 is mounted on the second shell 200. The speaker unit 300 will vibrate with the change of the electrical signal, generate air fluctuation (sound wave), and thus form the sound we hear

[0069] The first shell 100 is a flexible member, which can deform within a certain range when the speaker unit 300 vibrates, thereby effectively blocking the transmission resonance caused by the vibration of the speaker unit 300 and avoiding resonance noise, thereby improving the sound quality of the electronic device 20.

[0070] For example, the material of the flexible member can include but is not limited to silicone, rubber, etc.

[0071] As shown in Figure 6 and Figure 7 As shown, Figure 6 The displacement simulation test comparison chart of the speaker module 10 (curve X in the figure) of the embodiment of the present application and the prior art (curve Y in the figure) is given, Figure 7 The acceleration simulation test comparison chart of the speaker module 10 of the embodiment of the present application and the prior art is given.

[0072] As can be seen from the figure, under the same sound wave frequency, the vibration displacement and vibration acceleration of the X curve are lower than those of the Y curve, which means that the speaker module 10 of the embodiment of the present application can bring lower resonance energy transmission under the premise of ensuring the original performance and sound quality.

[0073] For example, the speaker unit 300 can be a conventional speaker unit, which can include but is not limited to a diaphragm, a coil and a magnetic circuit system, etc. The magnetic circuit system provides a magnetic field to drive the coil to move, thereby pushing the diaphragm to generate sound waves.

[0074] The material of the second shell 200 can be plastic to serve as a mounting and supporting function for the speaker unit 300.

[0075] Referring to Figure 3 and Figure 4 As shown, in some embodiments, the first shell 100 is provided with a connecting portion 110.

[0076] The first shell 100 is configured to be clamped with the electronic device 20 through the connecting portion 110.

[0077] In the above embodiment, the electronic device 20 can be provided with a mounting groove adapted to the connecting portion 110, and the first shell 100 is clamped corresponding to the mounting groove of the electronic device 20 through the connecting portion 110, so that the loudspeaker module 10 can be conveniently mounted on the electronic device 20.

[0078] Further, the connecting portion 110 is formed by the first shell 100 extending outwardly, and the connecting portion 110 is also a flexible member. The flexible deformation characteristic of the connecting portion 110 can adapt to the shape of the mounting groove during installation, so as to ensure that the connecting portion 110 is tightly fitted with the mounting groove, thereby forming a sealed clamping.

[0079] For example, referring to FIGS. 1 and 2, the C shell 40 of the notebook computer is provided with the above mounting groove on the side facing the D shell 50. Figure 3 Figure 4 For example, referring to FIGS. 1 and 2, the C shell 40 of the notebook computer is provided with the above mounting groove on the side facing the D shell 50.

[0080] For example, referring to FIGS. 1 and 2, the C shell 40 of the notebook computer is provided with the above mounting groove on the side facing the D shell 50. Figure 3 In some specific embodiments, the second shell 200 includes a main body portion 250 and a surrounding portion 260 surrounding the periphery of the main body portion 250, and the first shell 100 is a ring member.

[0081] The first shell 100 is connected with the surrounding portion 260 to form the mounting cavity 210.

[0082] The connecting portion 110 is circumferentially arranged around the first shell 100 away from the side of the surrounding portion 260.

[0083] In the above embodiment, the first shell 100 is a ring member, and the connecting portion 110 is circumferentially arranged around the first shell 100, so that the first shell 100 can form the mounting cavity 210 together with the C shell 40, the first shell 100 and the second shell 200 during installation, thereby reducing the cost.

[0084] Further, the first shell 100 is a ring member having two openings, so that the loudspeaker portion 300 can be conveniently mounted and dismounted. When the loudspeaker portion 300 is damaged and needs to be replaced, the first shell 100 can be directly repaired and replaced through the openings on the first shell 100, without the need to disassemble the first shell 100 and the second shell 200.

[0085] Figure 1 For example, referring to FIGS. 1 and 2, the C shell 40 of the notebook computer is provided with the above mounting groove on the side facing the D shell 50. Figure 2 In the prior art, the end of the plastic hard shell 30 of the loudspeaker is provided with a clamping portion 31 for clamping with the C shell 40. Further, a gap of 1 mm needs to be respectively arranged between the plastic hard shell 30 of the loudspeaker and the C shell 40 and the D shell 50 to reduce the transmission resonance.

[0086] ​​However, this will additionally increase the distance between the C shell 40 and the D shell 50 of the notebook computer, resulting in a large thickness of the notebook computer, which is inconvenient to carry. In addition, the vibration generated by the speaker unit will also be transmitted to the whole machine through the buckle part 31, which reduces the effect of the transmission resonance and is not good.

[0087] In the present application, the first shell 100 adopts a flexible piece, which can enable the first shell 100 to be directly connected with the C shell 40 of the notebook computer to form the mounting cavity 210, and only a gap is provided between the second shell 200 and the D shell 50, so that the distance between the C shell 40 and the D shell 50 can be shortened, and the notebook computer can be thinned; and the effect of blocking the transmission resonance caused by the vibration of the speaker unit 300 can be achieved.

[0088] Referring to Figures 3 to 5 , in some specific embodiments, the cross-sectional shape of the connecting part 110 is arc-shaped.

[0089] In the above embodiments, the connecting part 110 is designed in an arc shape, which can ensure that the connecting part 110 smoothly enters the mounting groove by the guiding effect of the arc surface when the connecting part 110 is inserted into the mounting groove of the C shell 40, thereby avoiding jamming.

[0090] Referring to Figure 5 , in some embodiments, the first shell 100 is provided with a first clamping part 120, and the second shell 200 is provided with a second clamping part 220.

[0100] In some embodiments, the mounting hole 230 can be provided on the enclosing portion 260 of the second shell 200 for mounting the speaker portion 300.

[0101] For example, the shape of the mounting hole 230 can be circular, rectangular, oval, etc., as long as it is suitable for the shape of the speaker portion 300, and the present application does not make too many restrictions on the shape.

[0102] In some specific embodiments, the first shell 100 is a silica gel piece.

[0103] In the above embodiment, the first shell 100 is a silica gel piece, which has softness and elasticity, and can effectively block the transmission resonance caused by the vibration of the speaker portion 300.
