DETAILED DESCRIPTION

Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

Reference is made to FIG. 1. FIG. 1 illustrates a schematic view of an electronic device 10 having a speaker 100 mounted therein. The electronic device 10 may be a laptop computer, a tablet computer, or a mobile device (e.g., a mobile phone), and the present disclosure is not limited in this respect. The electronic device 10 has a case 110 forming an accommodating space, and a rubber cabinet 130 and a driver 150 are disposed inside the case 110 for generating various types of sounds.

Reference is made to FIGS. 2-6. FIG. 2 illustrates a schematic view of the speaker 100. FIG. 3 illustrates a bottom view of the rubber cabinet 130, the driver 150, and a metal connection ring 170. FIG. 4 illustrates a cross-sectional view taken along line A-A in FIG. 2. FIG. 5 illustrates a schematic view of the metal connection ring 170. FIG. 6 illustrates another schematic view of the metal connection ring 170 taken from a view different from FIG. 5. In one or more embodiments of the present disclosure, the rubber cabinet 130 is fixed to the case 110, and the rubber cabinet 130 accommodates the driver 150. Moreover, the metal connection ring 170 is connected between the rubber cabinet 130 and the driver 150. The metal connection ring 170 surrounds the driver 150, and the rubber cabinet 130 surrounds the metal connection ring 170. The metal connection ring 170 includes a plurality of extension arms 171, and the extension arms 171 are spaced apart along an outer periphery of the metal connection ring 170. Moreover, the extension arms 171 are substantially T-shaped or mushroom-shaped, and thus the metal connection ring 170 can be stably fixed to the rubber cabinet 130 by the extension arms 171. The present disclosure is not limited in this respect. In some embodiments, each extension arm 171 has a first portion 171a and a second portion 171b, and the first portion 171a has a first width W1 greater than a second width W2 of the second portion 171b. Moreover, the first portion 171a is farther from a center of the metal connection ring 170 than the second portion 171b, so the metal connection ring 170 can be stably fixed to the rubber cabinet 130. Since the rubber cabinet 130 is made from rubber, a smaller assembly gap with adjacent elements can be maintained. Moreover, the rubber cabinet 130 can occupy a greater volume under the same accommodating space, and the material of the rubber cabinet 130 can further efficiently absorb sound waves generated by the driver 150, thereby preventing the sound waves from resonating with elements of the speaker 100 and generating noise.

During actual assembly, since it is hard to fix the rubber cabinet 130 to other elements using a general adhesive, spot glue or ultraviolet resin can be used to first fix the driver 150 to the metal connection ring 170. Moreover, an injection molding process can directly form rubber on the metal connection ring 170, and thus the rubber cabinet 130 can be obtained. The rubber cabinet 130 is then fixed to and disposed inside the case 110, such that the speaker 100 can be obtained. The present disclosure is not limited in this respect.

In one or more embodiments of the present disclosure, the rubber cabinet 130 includes a bending bottom 131, and a first portion 131a of the bending bottom 131 is fixed to the case 110 and extends outward from the rubber cabinet 130. Moreover, the speaker 100 includes a double-sided adhesive tape S, in which the double-sided adhesive tape S is configured for fixing the bending bottom 131 to the case 110. In practical applications, the double-sided adhesive tape S can stably fix the rubber cabinet 130 to other objects. The double-sided adhesive tape S is directly connected between the case 110 and the rubber cabinet 130. In addition, the double-sided adhesive tape S can be a double-sided acrylic tape or a double-sided silicon tape, and the present disclosure is not limited in this respect.

In one or more embodiments of the present disclosure, the metal connection ring 170 can be made of a metal or alloy, and a stamping process can be performed to the metal or alloy for forming the metal connection ring 170. A standard stamping machine can shape the metal or alloy, and then a cutting process and a bending process can be performed on the shaped metal or alloy for forming the metal connection ring 170 in a desired shape. In addition, the metal connection ring 170 can include a circular ring structure, a triangular ring structure, a square ring structure, or any polygonal ring structure. The “ring” described in the present disclosure can refer to an open surrounding structure or a closed surrounding structure, and the “ring” is not limited any shape. The rubber cabinet 130 includes a ring-shaped protrusion portion 133, and the metal connection ring 170 includes a ring-shaped recess 173. Therefore, the ring-shaped recess 173 can receive the ring-shaped protrusion portion 133. In some embodiments of the present disclosure, the ring-shaped recess 173 has a U-shaped cross section, and the rubber cabinet 130 and the metal connection ring 170 can be stably connected via the ring-shaped recess 173. In addition, the ring-shaped protrusion portion 133 can be a circular ring, a triangular ring, a square ring, or any polygonal ring. The ring-shaped recess 173 can include a circular ring recess, a triangular ring recess, a square ring recess, or any polygonal ring recess. The present disclosure is not limited in this respect.

In one or more embodiments of the present disclosure, the metal connection ring 170 includes a step-shaped interior edge 175, and the step-shaped interior edge 175 is ring-shaped and configured for fixing the driver 150. The step-shaped interior edge 175 can provide contacting surfaces in different directions for fixing the driver 150, and the driver 150 has an edge angle 151 corresponding in shape to the step-shaped interior edge 175. Therefore, the driver 150 is in close contact with the step-shaped interior edge 175 via the edge angle 151, and there is good stability between the metal connection ring 170 and the driver 150. The present disclosure is not limited in this respect.

FIG. 7 illustrates another cross-sectional view taken along line A-A in FIG. 2 in accordance with other embodiments of the present disclosure. In some embodiments of the present disclosure, the rubber cabinet 130 includes the bending bottom 131, in which a first portion 131a of the bending bottom 131 is fixed to the case 110a and extends outward from the rubber cabinet 130, and a second portion 131b of the bending bottom 131 is fixed to the case 110 and extends inward from the rubber cabinet 130. In short, the bending bottom 131 has the first portion 131a and the second portion 131b which respectively extend outward and inward from the rubber cabinet 130, and thus the first portion 131a and the second portion 131b respectively extend in two opposite directions. Therefore, the bending bottom 131 has a significant contacting surface, and the rubber cabinet 130 can be stably fixed to the case 110. The present disclosure is not limited in this respect.
