DETAILED DESCRIPTION

(7) To facilitate reading, this document points out upper, lower, left, and right according to the figures. Its objective is to point out relative reference locations of components, but not to limit this application.

(8) FIG. 1 is a schematic perspective diagram of a speaker 1. Referring to both FIG. 2 and FIG. 3, the speaker 1 includes a voice coil 25, a support piece 22, a washer 21, two wires 12, and a terminal component 11. The two wires 12 are substantially two parallel wires. The voice coil 25 includes two tensile wires 251 extending outward. The support piece 22 surrounds the voice coil 25. The two tensile wires 251 are located on an upper surface of the support piece 22. Preferably, the upper surface of the support piece 22 includes two tensile wire guiding slots 221 in which the two tensile wires 251 are placed. The washer 21 is located under the support piece 22. Preferably, the lower surface of the support piece 22 comprises a first wire guiding slot 222, an upper surface of the washer 21 comprises a second wire guiding slot 211, and the first wire guiding slot 222 and the second wire guiding slot 211 are corresponding to each other, so that the two wires 12 are located between the first wire guiding slot 222 and the second wire guiding slot 211. The two wires 12 are respectively connected to the two tensile wires 251, for example, directly welded to the two tensile wires 251. A connection hole 223 is disposed on an edge of the support piece 22, so that the two wires 12 extend downward to the terminal component 11 after the welding.

(9) The tensile wires 251 are welded to the wires 12 and, therefore, the support piece 22 may be prevented from being damaged by scalding. In addition, a terminal plate structure may be omitted when the wires 12 are used. Therefore, an external diameter of the support piece 22 may be less than an external diameter of a magnet 27, and an overall size of the speaker 1 may be further decreased.

(10) In an embodiment, the speaker 1 further includes a T-shaped yoke 23. The T-shaped yoke 23 includes a hole 231. The washer 21 includes a penetrating hole 212. The two wires 12 pass through the penetrating hole 212 and the hole 231. Preferably, the speaker 1 further includes an aluminum pipe 13 and the two wires 12 pass through the aluminum pipe 13. Two ends of the aluminum pipe 13 are located in the penetrating hole 212 of the washer 21 and the hole 231 of the T-shaped yoke 23, respectively. The aluminum pipe 13 additionally has a leading function, to lead the two wires 12 to successfully reach the terminal component 11, and prevent interference to and from another component (such as the T-shaped yoke or the magnet).

(11) In an embodiment, the speaker 1 further includes a heat dissipation chamber 10. The terminal component 11 is located in the heat dissipation chamber 10 and an outer surface of the heat dissipation chamber 10 is a plurality of heat dissipation fins. Preferably, the speaker 1 further includes a sound-absorbing sponge 26. The sound-absorbing sponge 26 is also located in the heat dissipation chamber 10 and the sound-absorbing sponge 26 is located above the terminal component 11. Not only does the heat dissipation chamber 10 provide internal space for placing the terminal component 13, but also the internal space of the heat dissipation chamber 10 may reduce a treble resonance frequency. The fin structure of the external surface of the heat dissipation chamber 10 may further speed up heat dissipation.

(12) Referring to FIG. 4A and FIG. 4B, the terminal component 11 includes two terminals, a sleeve seat 112, and two fixing heads 114. Each terminal includes a terminal head 1111 and a terminal body 111. The sleeve seat 112 includes two terminal blocks 1120. The two terminal blocks 1120 respectively accommodate the two terminal bodies 111, and the two terminal heads 1111 are exposed outside the sleeve seat 112. The two fixing heads 114 are respectively combined with the two terminal heads 1111, to respectively fasten two wires 12 to the two terminals. For example, the fixing heads 114 may be nuts or the like, and the terminal heads 1111 are of a stud type, so the fixing heads 114 and the terminal heads 1111 may be fastened to each other through screwing. The two wires 12 may surround the terminal heads 1111, and may be more strongly fastened by using a shim body 113. Preferably, each terminal head 111 includes a punch hole 110 through which the wires 12 may pass.

(13) The terminal component may be hidden inside the heat dissipation chamber (for example, a rear chamber of a tweeter) and does not occupy any external size. That is, an interface location is hidden at the bottom of the speaker. When an input signal line is connected, it needs only to use a standard plug as a wiring terminal, which is similar to a sound box wiring manner, and is convenient for inserting, removing, and changing the speaker. In this way, various disadvantages of solder wiring can be further prevented, thereby improving a compression effect, improving structural compactness and stability, and eliminating phase interference, to obtain a good linear reaction.

(14) Although this application is disclosed above by using the embodiments, the embodiments are not used for limiting this application. Any person skilled in the art may perform some modifications and improvements without disobeying the spirit and scope of this application. Therefore, the protection scope of this application should be subject to the scope defined by the claims.
