First leading sound subassembly includes first leading sound body and first support, and first leading sound body has first bottom, and first bottom is fixed on the first surface of damping lamellar body, and first support is connected in first leading sound body and is extended towards the direction of keeping away from the damping lamellar body. The first loudspeaker monomer is fixed on the first support and faces the first sound guide body, and a first distance is arranged between the first loudspeaker monomer and the first sound guide body. The second leads the sound subassembly and includes that the second leads the sound body and second support, and the second leads the sound body and has the second bottom, and the second bottom is fixed on the second surface of damping lamellar body, and the second leg joint leads the sound body and extends towards the direction of keeping away from the damping lamellar body in the second. The second loudspeaker monomer is fixed on the second support and faces the second sound guide body, and a second distance is arranged between the second loudspeaker monomer and the second sound guide body.
In summary, according to the composite speaker module of the embodiment of the invention, the first sound guiding assembly and the first speaker unit are mounted on the first surface of the vibration reduction sheet, and the second sound guiding assembly and the second speaker unit are mounted on the second surface of the vibration reduction sheet, so that the occupied volume of the composite speaker module can be reduced, and the composite speaker module can be assembled in advance and can be used for performing product testing independently. In addition, after the test is finished, the combined type horn module can be correspondingly assembled in the product shell only through the assembling part of the vibration reduction sheet body, so that the manufacturing and assembling working hours and working procedures are reduced, and the yield of products is improved.

In the embodiment, the damping sheet 10 is a circular sheet, but the damping sheet 10 can be a sheet with other shapes (such as square, rectangular or other irregular shapes), which can be determined according to the shape of the actual product. In some embodiments, the damping sheet 10 may be an elastic sheet and have a damping function, for example, the damping sheet 10 may be a foamed sheet, a rubber sheet or a plastic sheet made of Thermoplastic Polyurethane (TPU), Thermoplastic Elastomers (TPE), Thermoplastic Polyester Elastomers (TPEE), polystyrene Elastomers (TPEE) or Polycarbonate (PC).
As shown in fig. 2 and 3, in the present embodiment, the damping sheet 10 has a first surface 11 and a second surface 12 opposite to each other, that is, the first surface 11 and the second surface 12 are opposite sides of the damping sheet 10. The first sound guiding element 20 includes a first sound guiding body 21 and a first support 22, and in some embodiments, the first sound guiding body 21 may be a cone made of a hard material (e.g., plastic, metal, ceramic, acrylic, etc.) or a soft material (e.g., plastic, rubber, etc.) for guiding the direction of the sound waves output by the first speaker unit 30. In addition, the first sound guiding body 21 may be a solid cone or a hollow cone, which is not limited. The first sound guiding body 21 has a first bottom 211, and the first bottom 211 is fixed on the first surface 11 of the damping sheet body 10. For example, the first bottom 211 of the first sound guiding body 21 can be fixed on the first surface 11 by adhesion, locking, buckling, embedding, or integral molding. Similarly, the second sound guiding assembly 40 includes a second sound guiding body 41 and a second bracket 42, and the second bottom 411 of the second sound guiding body 41 is fixed on the second surface 12 of the vibration damping sheet 10, and the way of fixing the second sound guiding body 41 on the second surface 12 may be the same as or different from the way of fixing the first sound guiding body 21 on the first surface 11, and the way of combining the vibration damping sheet 10 with the first sound guiding body 21 and the second sound guiding body 41 will be further described below.
As shown in fig. 4, in the present embodiment, the first surface 11 and the second surface 12 of the damping sheet 10 of the composite speaker module 2 are respectively provided with an adhesive layer 111, 121, for example, the adhesive layer 111, 121 may be formed by an acrylic type (such as cyanoacrylate), a polysulfide type, a polyurethane type, or a silicone adhesive. The first bottom 211 of the first sound guiding body 21 (i.e. the bottom of the first sound guiding body 21) can be adhered and fixed on the first surface 11 of the damping sheet 10 corresponding to the adhesive layer 111. The second bottom 411 of the second sound guiding body 41 can be adhered and fixed on the second surface 12 corresponding to the adhesive layer 121.
Alternatively, as shown in fig. 5, in another embodiment, the vibration damping sheet 10 of the composite speaker module 2A is provided with at least one first fastening hole 101 (here, a plurality of first fastening holes 101) and at least one second fastening hole 102 (here, a plurality of second fastening holes 102), the first bottom 211 of the first sound guiding body 21 is provided with a plurality of first fasteners 214 corresponding to the first fastening holes 101, and the second bottom 411 of the second sound guiding body 41 is provided with a plurality of second fasteners 414 corresponding to the second fastening holes 102, wherein the first fasteners 214 and the second fasteners 414 may be barbs or bolts, but this is not limited. The first sound guiding body 21 is fixed in the vibration damping sheet 10 by the first fasteners 214 being fastened in the first fastening holes 101, and the second sound guiding body 41 is fixed in the vibration damping sheet 10 by the second fasteners 414 being fastened in the second fastening holes 102. In the embodiment, when the first sound guiding body 21 and the second sound guiding body 41 are both fastened and fixed on the vibration damping sheet 10, the first fastening holes 101 and the second fastening holes 102 on the vibration damping sheet 10 can be disposed in a staggered manner, so as to avoid the resonance problem caused by the interference or contact between the first sound guiding body 21 and the second sound guiding body 41 after fastening.
Alternatively, as shown in fig. 6, in another embodiment, the first sound guiding body 21 and the second sound guiding body 41 of the composite speaker module 2B can be fixed on the first surface 11 and the second surface 12 of the vibration damping sheet 10 by two-material injection molding, so as to further reduce the manufacturing and assembling time and process steps and improve the structural strength.
The above embodiments of fig. 4, 5 and 6 are only examples, and actually, the first sound guiding body 21 can also be fixed on the damping sheet 10 by other means (e.g. locking or clipping). In other embodiments, the first sound guiding body 21 and the second sound guiding body 41 can be fixed on the vibration damping sheet 10 by different methods. For example, in some embodiments, the first sound conductor 21 is fixed to the vibration damping sheet 10 in a snap-fit manner, and the second sound conductor 41 is fixed to the vibration damping sheet 10 in an adhesive manner. Alternatively, the first sound guide 21 is fixed to the vibration reduction sheet 10 by injection molding, and the second sound guide 41 is fixed to the vibration reduction sheet 10 by snap-fitting.
As shown in fig. 2 and fig. 3, the first support 22 of the first sound guiding assembly 20 of the composite speaker module 2 is connected to the first sound guiding body 21 and extends in a direction away from the vibration damping sheet 10, i.e. the extending direction of the first support 22 is perpendicular to the vibration damping sheet 10. The first speaker unit 30 is fixed on the first bracket 22 such that the first speaker unit 30 and the first sound guiding body 21 are separated by a first distance S1 (where the first distance S1 is a linear distance from the top of the first sound guiding body 21 to the first speaker unit 30), and the sound outlet surface of the first speaker unit 30 faces the first sound guiding body 21. On the other hand, the second support 42 of the second sound guiding assembly 40 is connected to the second sound guiding body 41 and extends perpendicularly away from the damping sheet body 10, that is, the first support 22 of the first sound guiding assembly 20 and the second support 42 of the second sound guiding assembly 40 extend in opposite directions. The second speaker unit 50 is fixed on the second bracket 42, so that the second speaker unit 50 and the second sound guiding body 41 are separated by a second distance S2, and the sound outlet surface of the second speaker unit 50 faces the second sound guiding body 41. In some embodiments, the first speaker unit 30 and the second speaker unit 50 may be various speakers, such as an electrodynamic speaker, an electromagnetic speaker, a piezoelectric speaker, an electrode speaker, a plasma speaker, or the like, but not limited thereto.
In some embodiments, the first horn unit 30 may be directly fixed or indirectly fixed to the first bracket 22. As shown in fig. 2 and fig. 3, the first speaker unit 30 may be covered with a first sound box 35, and the first sound box 35 is fixed (for example, adhered, locked or fastened) on the first bracket 22, so that the first speaker unit 30 can be indirectly fixed on the first bracket 22. In other embodiments, the first speaker unit 30 may also be directly fixed on the first bracket 22 without covering the first sound box 35, and the embodiment is not limited. Similarly, the second horn unit 50 may be directly fixed or indirectly fixed to the second bracket 42. In some embodiments, the second speaker unit 50 may be covered with a second sound box 55, so that the second speaker unit 50 may be indirectly fixed to the second bracket 42 through the second sound box 55. In other embodiments, the second speaker unit 50 may be directly fixed to the second bracket 42 without covering the second sound box 55.
As shown in fig. 2 and 3, an assembling portion 13 is disposed around the damping sheet 10, a connecting portion 4 is disposed in the housing 3, and the combined speaker module 2 can be correspondingly assembled and fixed to the connecting portion 4 through the assembling portion 13 of the damping sheet 10. In some embodiments, the assembling portion 13 and the combining portion 4 are structures that can be assembled with each other correspondingly. For example, in the embodiment shown in fig. 2 and 3, the assembling portion 13 includes a plurality of holes 131 disposed on the periphery of the damping sheet 10, and the combining portion 4 includes a plurality of locking holes 5 corresponding to the holes 131, so that the composite speaker module 2 can be fixed inside the housing 3 by passing a plurality of screws through the holes 131 and being locked to the locking holes 5. However, the above embodiments of the assembling portion 13 and the combining portion 4 are only examples, and the assembling portion 13 and the combining portion 4 may also be corresponding fasteners or adhesive layers, and the embodiments are not limited thereto.
Since the conventional technique needs to lock a plurality of speaker units and a plurality of sound guide assemblies inside the product housing one by one, an assembly mechanism and a vibration-proof mechanism must be respectively disposed on each assembly, resulting in a large volume of the product, high mechanism complexity, and complex and time-consuming assembly process. Moreover, the product must be inspected after all the components are assembled to the housing, and when the product is defective, the replacement of the internal components requires complicated disassembly and reassembly, which results in poor product assembly efficiency.
Therefore, the present invention assembles the first set of horn structures (the first sound guiding assembly 20 and the first horn unit 30) and the second set of horn structures (the second sound guiding assembly 40 and the second horn unit 50) on the same vibration reduction sheet 10 to form a composite horn module 2. Therefore, the two speaker structures can be damped by the damping sheet 10 without separately installing an assembling mechanism and a damping mechanism, thereby effectively reducing the complexity of the mechanism, the volume of the whole device and the manufacturing cost. Moreover, the composite speaker module 2 can be assembled in the product housing 3 by only using the single vibration-damping sheet 10, thereby eliminating the complex process of assembling each component in the housing 3. In addition, the composite horn module 2 of the present invention can be pre-tested and then assembled into the housing 3, thereby further reducing the assembly time and process steps and improving the yield of the product.
In addition, through the configuration of the composite horn module 2 of the above embodiments, the first horn unit 30 and the second horn unit 50 can be prevented from interfering with each other (e.g. resonance or sound wave interference) during operation, which is described below with reference to the accompanying drawings.
Referring to fig. 2 and 7, fig. 7 is a schematic diagram illustrating an operation of a speaker device according to a first embodiment of the present invention. In the present embodiment, when the first speaker unit 30 and the second speaker unit 50 operate, the first speaker unit 30 faces the first sound guiding body 21, so that the sound wave emitted from the first speaker unit 30 is transmitted toward the first sound guiding body 21 (as shown by arrow L1). When the sound wave is transmitted to the first sound guiding body 21, the transmission can be changed to the horizontal direction (as the X-axis direction in the figure) through the guidance of the conical surface of the first sound guiding body 21. The housing 3 is formed with a plurality of first sound outlets 6, and the first sound outlets 6 correspond to the peripheral sides of the first sound guiding bodies 21, so that the sound waves converted into the horizontal direction can be emitted from the first sound outlets 6 and transmitted to all sides of the speaker unit 1, and any position in the space where the speaker unit 1 is placed can be used for listening to the sound. Similarly, since the second speaker unit 50 faces the second sound guiding body 41, the sound wave emitted from the second speaker unit 50 is transmitted toward the second sound guiding body 41 (as shown by arrow L2), and when the sound wave is transmitted to the second sound guiding body 41, the sound wave is transmitted in the horizontal direction (as shown in the X-axis direction) by being guided by the conical surface of the second sound guiding body 41. The housing 3 is provided with a plurality of second sound outlets 7, and the second sound outlets 7 correspond to the peripheral sides of the second sound conductors 41, so that the sound waves in the horizontal direction can be transmitted from the second sound outlets 7 to all sides of the speaker unit 1. It should be further noted that, in fig. 2 and fig. 7, only the first sound outlet 6 and the second sound outlet 7 are shown in cross section, and other first sound outlets 6 and second sound outlets 7 are omitted for clearly showing various components in the housing 3.
By this, the sound wave guide that sends first loudspeaker unit 30 through first sound guide 21 to the horizontal direction, and pass through second sound guide 41 with the sound wave guide that second loudspeaker unit 50 sent to the horizontal direction to the separation of damping lamellar body 10 can effectively avoid first loudspeaker unit 30 and second loudspeaker unit 50's sound wave to interfere with each other or offset and reduce the power of sound between first loudspeaker unit 30 and second loudspeaker unit 50. In addition, the first sound guiding assembly 20, the first speaker unit 30, the second sound guiding assembly 40 and the second speaker unit 50 can also achieve the effect of vibration damping through the vibration damping sheet 10.
As further shown in fig. 2 and 3, in some embodiments, the first distance S1 between the first speaker unit 30 and the first sound guiding body 21 and the second distance S2 between the second speaker unit 50 and the second sound guiding body 41 may be the same or different according to different requirements. For example, when the first speaker unit 30 and the second speaker unit 50 are different speakers (e.g., the first speaker unit 30 is a woofer and the second speaker unit 50 is a tweeter), the first distance S1 and the second distance S2 are different. When the first horn unit 30 and the second horn unit 50 are the same horn, the first distance S1 and the second distance S2 are the same, but the invention is not limited thereto.
In some embodiments, the tapered surface of the first sound guiding body 21 may be a non-linear tapered surface or a linear tapered surface, and the tapered surface of the second sound guiding body 41 may also be a non-linear tapered surface or a linear tapered surface. In addition, the tapered surface of the first sound guiding body 21 and the tapered surface of the second sound guiding body 41 can be set to be the same or different according to different requirements.
For example, as shown in fig. 2, in the present embodiment, the first sound guiding body 21 has a first non-linear conical surface 212 (here, a curved surface), and the second sound guiding body 41 has a second non-linear conical surface 412 (here, a curved surface). When the first horn unit 30 and the second horn unit 50 are different horns (for example, the first horn unit 30 is a woofer and the second horn unit 50 is a tweeter), the curvature of the first nonlinear conical surface 212 and the curvature of the second nonlinear conical surface 412 are set to be different, for example, in the present embodiment, the curvature of the first nonlinear conical surface 212 is greater than the curvature of the second nonlinear conical surface 412. In other embodiments, the first non-linear conical surface 212 and the second non-linear conical surface 412 may have different curvature configurations according to other factors (e.g., different decoration environments or special audio requirements), and the embodiment is not limited thereto.
In some embodiments, as shown in fig. 8, the first sound guiding body 21 of the composite speaker module 2C has a first linear conical surface 213 (where the cross section of the first linear conical surface 213 is an inclined surface), and the second sound guiding body 41 has a second linear conical surface 413 (where the cross section of the second linear conical surface 413 is an inclined surface). When the first horn unit 30 and the second horn unit 50 are different horns (for example, the first horn unit 30 is a woofer and the second horn unit 50 is a tweeter), the slope of the first linear conical surface 213 and the slope of the second linear conical surface 413 are set to be different. For example, in the present embodiment, the slope of the first linear conical surface 213 is greater than the slope of the second linear conical surface 413, but this is not a limitation.
In some embodiments, at least one of the first support 22 of the first sound guiding assembly 20 and the second support 42 of the second sound guiding assembly 40 may be provided with a wire arrangement groove. As shown in fig. 9, a wire-arranging groove 222 is formed on an outer side of one of the first brackets 22 of the composite horn module 2D, wherein an extending direction of the wire-arranging groove 222 is the same as an extending direction of the first bracket 22.
