The sound wave of the loudspeaker rear cavity can also be utilized through the inverse phase pipe, thereby enhancing the loudness of the sound. However, the existing inverse phase pipe is generally made of metal material. The inverse phase pipe of this form has great strength and is not easy to deform, which can effectively improve the Q value (quality factor in resonance state) of the inverse phase pipe. The greater the Q value, the higher the frequency stability of the inverse phase pipe, and the better the energy storage efficiency. However, in actual products, the inverse phase pipe needs to be adapted to the shape and size of the loudspeaker rear cavity. Especially for miniature loudspeakers, the size of the loudspeaker itself is very small, and the length, inner diameter and outer diameter of the inverse phase pipe are greatly limited.

[0045] Embodiment

[0046] Reference Figures 1-12 The embodiment discloses a loudspeaker assembly, which comprises a housing 10, a loudspeaker 20 and an inverter tube 30.

[0047] The shell 10 is internally formed with a receiving cavity 101;

[0048] The loudspeaker 20 is placed in the receiving cavity 101, as shown in Figure 4 and Figure 9 The loudspeaker 20 includes a diaphragm 201, which separates the receiving cavity 101 into a front cavity 1011 and a rear cavity 1012, the front cavity 1011 being in communication with the outside, so that the sound of the front cavity 1011 can be radiated to the outside;

[0049] As shown in Figures 4-7 The inverter tube 30 is arranged in the receiving cavity 101, one end of the inverter tube 30 being in communication with the rear cavity 1012, and the other end being in communication with the outside, so that the sound of the rear cavity 1012 can be radiated to the outside through the inverter tube 30;

[0050] As shown in Figure 5 The inverter tube 30 includes a deformable hose 301, and it can be understood that the inverter tube 30 can have only a part of the hose, or can be entirely made of the hose.

[0051] In the above structure, the inverter tube 30 can be flexibly bent according to the shape of the installation space by the arrangement of the hose 301, thereby well adapting to the needs of different installation spaces, especially the narrow space inside the miniature assembly, making the installation more convenient, and also facilitating the reduction of processing cost, ensuring the Q value (quality factor in resonance state) of the inverter tube and the performance of the inverter tube radiated sound energy, and reducing the low-frequency amplitude of the loudspeaker diaphragm, reducing distortion and improving sound quality.

[0052] In addition, the inverter tube 30 with the hose 301 can be bent, thereby ensuring sufficient length in limited space, facilitating the increase of the length of the sound propagation path.

[0053] The cross-sectional shape of the inverter tube 30 is not limited, and can be rectangular, circular, oval, etc.

[0054] In some embodiments, as shown in Figures 10-12 The inverter tube 30 further includes a hard tube 302, one end of the hose 301 being connected with the hard tube 302, the hard tube 302 being in communication with the hose 301, or both ends of the hose 301 being connected with the hard tube 302.

[0055] In another way, the inverter tube 30 can only include a hose 301, one end or both ends of the hose 301 being connected with a hard tube; for example, as shown in Figure 10 The inverter tube 30 includes an arc-shaped hose 301, both ends of the arc-shaped hose 301 being connected with the hard tube 302; or, as shown in Figure 11 and Figure 12As shown, one end of the curved flexible tube 301 is connected to a rigid tube 302. Understandably, the shape of the curved flexible tube 301 can be changed.

[0056] Alternatively, the phase inverter 30 may also include multiple flexible hoses 301, with a rigid tube connecting adjacent flexible hoses 301.

[0057] Understandably, the rigid tube 302 has a higher hardness than the flexible tube 301. The rigid tube 302 has higher rigidity, is not easily bent or deformed, and can basically maintain a fixed shape; while the flexible tube 301 has higher flexibility and plasticity, and is easy to bend and deform.

[0058] The aforementioned rigid pipe 302 can be a metal pipe or a rigid plastic pipe, and the flexible pipe 301 can be a flexible plastic pipe. For example, the flexible pipe 301 can be made of one or more materials selected from PVC (polyvinyl chloride), PP (polypropylene), PE (polyethylene), TPE (thermoplastic elastomer), and HDPE (high-density polyethylene).

[0059] The material of the aforementioned housing 10 can be the same as that of the rigid tube 302.

[0060] The aforementioned "rigid tube 302 + flexible tube 301" structure is more conducive to ensuring the Q value (quality factor in resonant state) of the bass reflex tube 30, improving the low-frequency response of the speaker assembly, and reducing the low-frequency harmonic distortion of the speaker.

[0061] In some implementations, the wall thickness of the flexible tube 301 is not less than the wall thickness of the rigid tube 302, so as to better ensure the Q value (quality factor in resonant state) of the bass reflex tube, thereby better ensuring the sound effect.

[0062] In some implementations, the wall thickness of the rigid tube 302 is less than 2 mm, which is more conducive to reducing acoustic loss and thus improving the Q value.

[0063] In some implementations, the connection between the flexible hose 301 and the rigid hose 302 can be made in the following manner:

[0064] like Figure 13 As shown, the inner diameter of the flexible tube 301 is not less than the outer diameter of the rigid tube 302, so that the flexible tube 301 can be sleeved on the outside of the rigid tube 302.

[0065] Or, such as Figure 14 As shown, the outer diameter of the flexible tube 301 is not greater than the inner diameter of the rigid tube 302, and at this time the flexible tube 301 is located inside the rigid tube 302.

[0066] Or, for example Figure 15As shown, the outer diameter of the hose 301 is not less than the outer diameter of the hard tube 302, and the inner diameter of the hose 301 is less than the outer diameter of the hard tube 302, in this way, the hose 301 and the hard tube 302 can be connected and sealed by bonding.

[0067] It can be understood that when the hose 301 and the hard tube 302 are connected in the above three ways, the sealing of the connection should be ensured, and the connection can be achieved by bonding or other ways.

[0068] In some embodiments, the unfolded length of the hose 301 is a first unfolded length, and the unfolded length of the entire inverter tube 30 is a second unfolded length, and the ratio of the first unfolded length to the second unfolded length is not less than 0.1, so as to better ensure the Q value of the inverter tube on the basis of ensuring the deformation ability of the inverter tube.

[0069] It can be understood that if the entire inverter tube 30 is a hose, the ratio of the first unfolded length to the second unfolded length is 1.

[0070] For example, when the entire inverter tube 30 is in a U shape, the middle part is an arc-shaped hose 301, and the two sides are straight hard tubes 302, the first unfolded length can be understood as the arc length of the middle arc-shaped hose 301, and the second unfolded length is the sum of the arc length of the middle arc-shaped hose 301 and the length of the two straight hard tubes 302.

[0071] The above-mentioned hard tube 302 can be a straight tube, a curved tube or a tube with other shapes.

[0072] In some embodiments, the shell 10 includes a seat body 102 and a cover plate 103, the cover plate 103 is connected to the seat body 102, the seat body 102 forms an accommodating cavity 101 inside, and the accommodating cavity 101 has an opening which is covered by the cover plate 103.

[0073] The cover plate 103 and the seat body 102 can be connected by welding or bonding.

[0074] In one embodiment, the shell 10 is provided with a first sound outlet hole 104 which communicates with the outside, so that the front cavity 1011 communicates with the first sound outlet hole 104, so that the front cavity 1011 communicates with the outside through the first sound outlet hole 104, thereby realizing the transmission of sound.

[0075] The front cavity 1011 and the inverter tube 30 can also be connected to the first sound outlet hole 104, so that the sound of the front cavity 1011 and the rear cavity 1012 is transmitted to the outside through the first sound outlet hole 104, thereby realizing the transmission of sound.

[0076] In another way, Figure 1 and Figure 5As shown, the housing 10 is provided with a first sound outlet 104 and a second sound outlet 105 that are separated from each other. Both the first sound outlet 104 and the second sound outlet 105 are connected to the outside. The front cavity 1011 is connected to the first sound outlet 104, so that the sound of the front cavity 1011 can be transmitted to the outside through the first sound outlet 104. One end of the phase inverter 30 is connected to the rear cavity 1012, and the other end is connected to the second sound outlet 105, so that the sound of the rear cavity 1012 can be transmitted to the outside through the second sound outlet 105 after passing through the phase inverter 30.

[0077] Furthermore, the first sound outlet 104 and the second sound outlet 105 are located on the same side of the housing 10, so that the sound from the front cavity 1011 and the rear cavity 1012 can radiate outward in the same direction, which is beneficial to improving the low-frequency loudness.

[0078] The second sound outlet 105 not only transmits sound, but also provides some heat dissipation and pressure relief.

[0079] The dimensions of the first sound outlet 104 and the second sound outlet 105 can be designed according to actual needs.

[0080] To ensure the reliability and sealing of the bass reflex tube 30, the connection end of the bass reflex tube 30 to the housing can be wrapped with filler before being connected to the housing 10. The other end can be in direct contact with the inner wall of the housing 10, or wrapped with filler before contacting the inner wall of the housing 10 to ensure reliable fixation, or it can be suspended. For example, the connection end of the bass reflex tube 30 to the second sound outlet can be wrapped with filler before being connected, and the other end of the bass reflex tube 30 can be fixed in the rear cavity 1012.

[0081] In some embodiments, dustproof nets are connected to both the first sound outlet 104 and the second sound outlet 105 to prevent external impurities from entering the interior of the sound outlet.

[0082] The number of the aforementioned phase inverter tubes 30 can be one or more, and the number of the corresponding second sound outlet holes 105 can be one or more.

[0083] In one implementation, such as Figure 6 and Figure 8 As shown, the accommodating cavity 101 has a first mounting surface 1013, and a support frame 1014 protruding from the first mounting surface 1013 is provided on the first mounting surface 1013. The speaker 20 is connected to the support frame 1014, and the diaphragm 201 of the speaker 20 is disposed facing the first mounting surface 1013. The edge of the diaphragm 201 abuts against the support frame. The diaphragm 201 of the speaker 20, the support frame 1014 and the first mounting surface 1013 together form a front cavity 1011. The remaining cavity in the accommodating cavity 101 after removing the front cavity 1011 forms a rear cavity 1012.

[0084] The embodiment also discloses an electronic device comprising the loudspeaker assembly.

[0085] All the optional technical solutions can be combined to form optional embodiments of the utility model, that is, any multiple embodiments can be combined to meet the needs of different application scenarios, which are all within the protection scope of the application and will not be described one by one here.

[0086] It should be noted that the above embodiments are merely examples for clear illustration, and are not limitations on the embodiments. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
