Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of loudspeakers, in particular to a double-face different-axis combined loudspeaker and electronic equipment. BACKGROUND

[0002] In the traditional loudspeaker design, in order to realize the separation and presentation of high and low frequencies, some loudspeakers adopt the coaxial design of high and low frequency units in up-down symmetry. This design makes the sound emitting directions of high and low frequency units opposite, which can theoretically achieve a certain balance and harmony of sound. However, in actual market application, this design of coaxial and opposite sound emitting directions gradually shows limitations.

[0003] With the continuous improvement of consumers' requirements for sound quality experience, the single sound emitting direction and coaxial design can no longer meet the diversified use requirements. For example, the loudspeaker with high and low frequency units in coaxial design has a narrow sound field, and the radiation angles of high and low frequencies are limited, which limits the width and depth of the sound field, especially in high-end application scenarios such as home theater and professional audio.

[0004] At present, there is no effective technical solution to the above problems. CONTENT OF THE INVENTION

[0012] The double-face different-axis combined speaker of the present application divides the shell into an upper shell and a lower shell, facilitating the assembly of the speaker.

[0013] The double-face different-axis combined speaker, wherein the bottom of the tweeter unit comprises a first yoke;

[0014] The shell forms a transition cavity, the tweeter unit has a first cavity, and the first yoke has a plurality of air holes communicating the first cavity and the transition cavity.

[0015] The double-face different-axis combined speaker of the present application is provided with air holes on the first yoke to pass through the first cavity and the transition cavity, so that the gas in the first cavity heated by the voice coil can be quickly transferred to the transition cavity for heat dissipation under the action of vibration, thereby avoiding the temperature rise of the first voice coil under high-intensity work, and improving the service life of the tweeter unit.

[0016] The double-face different-axis combined speaker, wherein the air holes are arranged away from the yoke platform.

[0017] The double-face different-axis combined speaker, wherein the length of the yoke platform is less than or equal to the length of the bottom surface of the first yoke, and / or the width of the yoke platform is less than or equal to the width of the bottom surface of the first yoke.

[0019] The double-face different-axis combined speaker, wherein the top of the second yoke has a third opening, the yoke platform is located in the third opening, and the high side edge of the third opening is connected.

[0020] The double-face different-axis combined speaker, wherein the inside of the second opening has a stepped groove, and the bass unit is limitingly installed on the stepped groove.

[0021] The double-face different-axis combined speaker, wherein the included angle between the direction of the second opening and the vertical direction is 10-25°.

[0022] In a second aspect, the present application further provides an electronic device comprising the double-face different-axis combined speaker provided in the first aspect.

For simplicity of the disclosure, the description below refers to the components of a specific example by reference number. In practice, each example can include components not expressly shown or described. Furthermore, one having ordinary skill in the art will understand that they can be deployed in other examples with different components or in different configurations. Similarly, the disclosure can be used in different examples with different processing systems, different materials, and so on. It is intended that the present application covers all such uses.

[0035] In a first aspect, refer to Figures 1-5 Some embodiments of the present application provide a double-face different-axis combined loudspeaker, comprising: a shell 1, a tweeter unit 2 and a woofer unit 3;

[0036] The shell 1 has a first opening 11 vertically upward arranged at the top, and a second opening 12 obliquely downward arranged at the bottom;

[0037] The tweeter unit 2 is sealingly installed in the first opening 11, and the woofer unit 3 is sealingly installed in the second opening 12;

[0038] The woofer unit 3 has a yoke platform 4 at the top for supporting the bottom of the tweeter unit 2.

[0039] Specifically, the tweeter unit 2 refers to the part of the loudspeaker system responsible for reproducing high-frequency sound; the woofer unit 3 refers to the part of the loudspeaker system responsible for reproducing low-frequency sound; both are integrated in the same loudspeaker, which can maintain the compact structure of the tweeter unit 2 and the woofer unit 3, avoiding the complexity of the separated design.

[0040] More specifically, the shell 1 refers to the external structure that wraps and connects the assembled tweeter unit 2 and woofer unit 3, which can be made of plastic or metal material.

[0041] More specifically, the first opening 11 and the second opening 12 on the shell 1 respectively define the installation position and sound emission direction of the tweeter unit 2 and the woofer unit 3, wherein the vertically upward arranged first opening 11 and the obliquely downward arranged second opening 12 can respectively determine the sound emission direction of the tweeter unit 2 as vertically upward and the sound emission direction of the woofer unit 3 as obliquely downward, so that they constitute different-axis sound emission directions. Compared with the traditional coaxial loudspeaker, the radiation angle under the combination of high and low frequencies is changed, which can effectively improve the width and depth of the sound field, especially suitable for high-end application scenarios such as home theater, professional audio, etc., to produce more stereo, wide sound field effect and more delicate, distinct sound quality level.

[0042] More specifically, in addition to increasing the combination structure of different axes, the double-face different-axis combination loudspeaker of the embodiment of the application also increases the yoke platform part 4 as the connecting support part between the high-frequency monomer 2 and the low-frequency monomer 3, the yoke platform part 4 is obtained based on the modification of the yoke part of the low-frequency monomer 3 (i.e. the second yoke 31 below), and the yoke platform part 4 has a horizontally arranged platform surface for supporting the bottom of the high-frequency monomer 2, so that the high-frequency monomer 2 and the low-frequency monomer 3 are compactly installed in the shell 1, which can effectively improve the compactness and stability of the whole loudspeaker; wherein the yoke platform part 4 can be in contact with the bottom of the high-frequency monomer 2, and can also support and fix the bottom of the high-frequency monomer 2 by means of glue or the like.

[0043] It should be noted that the sealed installation refers to the installation mode of sealing and fixing by means of glue or buckle.

[0044] The double-face different-axis combination loudspeaker of the embodiment of the application modifies the high-frequency monomer 2 and the low-frequency monomer 3 to be vertically upward and obliquely downward respectively based on the design of the shell 1, which constitutes the sound emitting direction of different axes, can effectively improve the width and depth of the sound field, so as to produce more stereoscopic, wide sound field effect and more delicate, distinct sound quality level, and also increases the yoke platform part 4 connected to the low-frequency monomer 3 and supporting the bottom of the high-frequency monomer 2 as the connecting support part between the high-frequency monomer 2 and the low-frequency monomer 3, which can effectively improve the compactness and stability of the whole loudspeaker.

[0045] In some preferred embodiments, the shell 1 includes an upper shell 13 and a lower shell 14, and the upper shell 13 is fixedly connected with the lower shell 14.

[0046] Specifically, as shown in Figure 2 the first opening 11 is located in the middle of the upper shell 13, and the second opening 12 is located in the middle of the lower shell 14.

[0047] More specifically, the double-face different-axis combination loudspeaker of the embodiment of the application divides the shell 1 into the upper shell 13 and the lower shell 14, which facilitates the assembly of the loudspeaker; in the actual production process, the worker can first seal and install the high-frequency monomer 2 in the first opening 11 of the upper shell 13, and seal and install the low-frequency monomer 3 in the second opening 12 of the lower shell 14, and then connect the upper shell 13 with the high-frequency monomer 2 in the lower shell 14 with the installed low-frequency monomer 3, so as to complete the assembly of the whole loudspeaker.

[0048] More specifically, in other assembly methods, the worker can also first seal the bass unit 3 in the second opening 12 of the lower shell 14, then buckle the upper shell 13 in the lower shell 14 with the bass unit 3 installed, then set the treble unit 2 on the yoke platform 4 through the first opening 11, and then seal and install the treble unit 2 to fix it on the upper shell 13 to complete the assembly of the entire loudspeaker. This installation method can further ensure that the yoke platform 4 can effectively support the bottom of the treble unit 2, thereby further improving the compactness and stability of the product.

[0049] In some preferred embodiments, the bottom of the treble unit 2 includes a first yoke 21;

[0050] The shell 1 encloses a transition cavity 15, the treble unit 2 has a first cavity 27, and the first yoke 21 has a plurality of air holes 28 that communicate the first cavity 27 and the transition cavity 15.

[0051] Specifically, the treble unit 2 includes various structural components required for sound production, such as Figure 2 and Figure 3 As shown, it also includes a first frame 22, a first magnet 23, a first voice coil 24, a first dust cap 25, and a first diaphragm 26. The first diaphragm 26, the first frame 22, and the first yoke 21 are sequentially and sealingly connected to enclose the first cavity 27. The first magnet 23 is fixed on the first yoke 21, the first dust cap 25 is fixed on the top of the first magnet 23, and the first magnet 23 has a first gap with the first yoke 21 around its periphery. One end of the first voice coil 24 is fixed on the first diaphragm 26, and the other end is located in the first gap. The upper shell 13 is sealingly connected with the first frame 22, and the top of the yoke platform 4 supports the bottom of the first yoke 21. The transition cavity 15 enclosed by the shell 1 is a region inside the shell 1 that is independent of the interiors of the treble unit 2 and the bass unit 3.

[0052] More specifically, during the sound production of the treble unit 2, the continuously vibrating first voice coil 24 generates heat. If the heat dissipation effect of the treble unit 2 is poor, it can easily lead to continuous temperature rise of the first voice coil 24, and even cause demagnetization or glue melting or voice coil burning, thereby damaging the entire treble unit 2. Therefore, the double-sided and off-axis combined loudspeaker of the present application is provided with air holes 28 on the first yoke 21 to communicate the first cavity 27 and the transition cavity 15, so that the gas in the first cavity 27 that is heated by the voice coil can be quickly transferred to the transition cavity 15 for heat dissipation under the action of vibration, thereby avoiding the temperature rise of the first voice coil 24 under high-intensity work, and improving the service life of the treble unit 2.

[0053] More specifically, the air vent hole 28 can be one or more, but setting too many air vent holes 28 can affect the sound production effect of the treble unit 2, therefore, in the embodiment of the present application, the air vent hole 28 is preferably one.

[0054] More specifically, in this implementation, the communication area formed by the transition cavity 15 and the first cavity 27 is isolated from the inside of the bass unit 3, which can ensure that the treble unit 2 and the bass unit 3 do not interfere with each other when working together.

[0055] In some preferred embodiments, the air vent hole 28 avoids the yoke platform part 4.

[0056] Specifically, the position of the air vent hole 28 needs to avoid the yoke platform part 4 to be designed to avoid the yoke platform part 4 partially or completely shielding the air vent hole 28 and affecting the gas conduction ability of the air vent hole 28.

[0057] More specifically, in order to improve the heat dissipation effect of the air vent hole 28, the air vent hole 28 is preferably arranged at the bottom of the first yoke 21, so that the air vent hole 28 can guide the temperature rise gas to diffuse and cool down from top to bottom.

[0058] More specifically, the internal structure of the bass unit 3 installed obliquely downward is distributed high and low, and the transition cavity 15 also forms areas with different cross-sectional sizes, in the embodiment of the present application, as shown in Figure 2 , the air vent hole 28 is preferably arranged near the lower side of the bass unit 3, so that the lower part of the air vent hole 28 corresponds to the area with a larger cross section in the transition cavity 15, thereby further facilitating the diffusion and cooling of the temperature rise gas through the air vent hole 28.

[0059] In some preferred embodiments, the length of the yoke platform part 4 is less than or equal to the length of the bottom surface of the first yoke 21, and / or the width of the yoke platform part 4 is less than or equal to the width of the bottom surface of the first yoke 21.

[0060] Specifically, the length of the yoke platform part 4 is designed to be less than or equal to the length of the bottom surface of the first yoke 21 and / or the width of the yoke platform part 4 is designed to be less than or equal to the width of the bottom surface of the first yoke 21, which ensures that the air vent hole 28 can be arranged on the bottom surface of the first yoke 21 to avoid the yoke platform part 4, and further enables the air vent hole 28 to guide the temperature rise gas to diffuse and cool down through the air vent from top to bottom.

[0061] In some preferred embodiments, the bass unit 3 includes a second yoke 31 in the shape of a downwardly inclined cover body, and the second yoke 31 is bent at the top to form the yoke platform part 4.

[0062] Specifically, the bass unit 3 includes various structural components required for sound production, such as Figure 2 and Figure 3As shown, the bass driver 3 also includes a second frame 32, a second magnet 33, a second voice coil 34, a second washer 35, and a second diaphragm 36. The second diaphragm 36, the second frame 32, the second yoke 31, and the second magnet 33, which are sequentially sealed together, form a second cavity 37. The second washer 35 is fixed to the bottom of the second magnet 33. There is a second gap between the outer periphery of the second magnet 33 and the second yoke 31. One end of the second voice coil 34 is fixed to the second diaphragm 36, and the other end is located in the second gap. The lower housing 14 is sealed to the second frame 32. The yoke platform 4 is integrally formed with the second yoke 31. One end of the yoke platform 4 is connected to the second yoke 31, and the other end has a horizontally extending plate-like structure to support the bottom of the first yoke 21.

[0063] More specifically, the yoke platform 4 is formed by bending the top of the second yoke 31. In actual production, workers can make the yoke platform 4 by stamping or bending the original second yoke 31 without adding extra materials to prepare the yoke platform 4, which can effectively save the material cost of the speaker. Secondly, the design of the yoke platform 4 and the second yoke 31 being integrally formed can further improve the compactness and stability of the product.

[0064] In some preferred embodiments, the top of the second yoke 31 has a third opening 38, the yoke platform portion 4 is located within the third opening 38 and is connected to the high side of the third opening 38.

[0065] Specifically, in this embodiment, the second magnet 33 is fixed on the second yoke 31 and seals the third opening 38, which can isolate the transition cavity 15 from the middle of the second cavity 37. In the top view, the three edges of the yoke platform 4, except for the edge connected to the second yoke 31, have gaps between them and the edges corresponding to the third opening 38, so that the yoke platform 4 can be bent to a horizontal state to support the tweeter 2.

[0066] In some preferred embodiments, the second yoke 31 is in the shape of a rectangular cover, with a bayonet 39 at each of its four corners.

[0067] Specifically, such as Figure 4 As shown, the four corners of the second yoke 31 are provided with bayonets 39 so that the four sides of the rectangular cover-shaped second yoke 31 can form four bent edges to be inserted into the second frame 32 for installation and fixation. The bending angle of the bent edges can be slightly adjusted based on the elasticity of the material to ensure the stability of the connection between the second frame 32 and the second yoke 31.

[0068] In some preferred embodiments, the inner side of the second opening 12 has a stepped groove 16, and the bass driver 3 is mounted on the stepped groove 16.

[0069] Specifically, based on the foregoing, the bass unit 3 supports the treble unit 2 through the yoke platform 4, and in order to further improve the structural stability of the product, the stepped groove 16 is designed to limit the installation of the bass unit 3, thereby further strengthening the supporting capacity of the bass unit 3.

[0070] In some more preferred embodiments, the second frame 32 has a secondary stepped groove 16 on the inner side, and the second yoke 31 is limitedly installed on the secondary stepped groove 16, thereby further strengthening the supporting capacity of the bass unit 3 and improving the structural stability of the product.

[0071] In some preferred embodiments, the second opening 12 has an angle of 10-25° with the vertical direction.

[0072] Specifically, the angle of the second opening 12 with the vertical direction determines the difference in the sound emission axis direction of the treble unit 2 and the bass unit 3, and setting it to 10-25° can basically meet the use requirements of various different-axis sound emission scenes, especially suitable for high-end application scenes such as home theaters and professional sound systems, and can produce a more three-dimensional, wide sound field effect and more delicate, distinct sound quality levels.

[0073] In a second aspect, some embodiments of the present application further provide an electronic device comprising the double-sided different-axis combined loudspeaker provided in the first aspect.

[0074] In the description of the present specification, the description of the terms "one embodiment", "certain embodiments", "illustrative embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0075] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
