All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 7, the present invention provides a speaker box 100, where the speaker box 100 includes an upper cover 10, a lower cover 30 cooperating with the upper cover 10 to form an accommodating space, a speaker unit 50 accommodated in the accommodating space, and a heat conducting member 70 for guiding heat generated by a heat generating component into the speaker box 100.
The heat conducting member 70 includes an input end 71 connected to the heat generating component, an output end 73 disposed in the accommodating space, and a connecting portion 75 connecting the input end 71 and the output end 73. The output end 73 is annular and is sandwiched between the speaker unit 50 and the upper cover 10.
In the present embodiment, the input end 71, the output end 73, and the connection portion 75 are integrally molded. Thereby increasing the connection stability between the input terminal 71, the output terminal 73, and the connection part 75. Meanwhile, by disposing the output terminal 73 in a ring shape, the heat dissipation area of the heat conductive member 70 is increased, thereby improving the heat dissipation efficiency of the speaker box 100.
The speaker unit 50 includes a diaphragm 51 for vibrating and sounding, and the accommodating space includes a front acoustic cavity 101 formed by the diaphragm 51 and the upper cover 10 at an interval, and a rear cavity 102 opposite to the front acoustic cavity 101. The output end 73 is disposed in the front acoustic cavity 101, and the heat conducting member 70 is used for conducting heat generated by the heat generating component to the front acoustic cavity 101.
Specifically, the diaphragm 51 includes a spherical top portion 511, a corrugated portion 513 extending outward from the spherical top portion 511, and a fixing portion 515 extending outward from the corrugated portion 513. Further, the output end 73 is interposed between the fixing portion 515 and the upper cover 10.
The upper cover 10 includes a top wall 11 disposed opposite to the lower cover 30, a side wall 13 extending from a peripheral edge of the top wall 11 toward the lower cover 30, and a support wall 15 extending from the top wall 11 toward the lower cover 30 and fixing the speaker unit 50. Further, the output end 73 is sandwiched between the support wall 15 and the diaphragm 51.
Specifically, the top wall 11 includes a steel plate 111 disposed opposite to the speaker unit 50.
The side wall 13 is provided with a through hole 131 and a sound guide channel 133 for communicating the front sound cavity 101 with the outside. The heat conduction member 70 enters the front acoustic chamber 101 through the through hole 131.
The supporting wall 15 is provided with a groove 151 formed by recessing from the surface of the supporting wall close to the accommodating space to the direction far away from the accommodating space. The supporting wall 15 includes a first surface 1511 surrounding the groove 151 and disposed opposite to the fixing portion 515, a second surface 1513 opposite to the first surface 1511, and a third surface 1515 connecting the first surface 1511 and the second surface 1513.
The plane of the second surface 1513 and the fixing portion 515 is the same plane, one side of the output end 73 close to the lower cover 30 is fixedly connected with the fixing portion 515 and the second surface 1513, and one side of the output end 73 far away from the lower cover 30 is fixedly connected with the first surface 1511. That is, the output end 73 is partially received in the groove 151.
The through hole 131 formed in the side wall 13 communicates the groove 151 with the outside, and the connection portion 75 of the heat conducting member 70 passes through the through hole 131 and is connected to the input end 71.
In this embodiment, the heat-conducting member 70 is a solid structure. Of course, in other embodiments, the heat conducting member 70 may be a hollow structure, the heat conducting member 70 has a hollow area, and the hollow area is filled with condensate, so as to increase the heat dissipation effect of the heat conducting member 70. Even, the heat conducting member 70 may also be any other structure capable of conducting heat, that is, only the heat conducting member 70 needs to conduct the heat of the heat generating component to the front acoustic cavity 101, so as to dissipate the heat through the front acoustic cavity 101.
The working principle of the heat dissipation of the speaker box 100 is as follows: when the speaker box 100 is in heat dissipation operation, a low-frequency (lower than 1000Hz) pulse signal can be input to drive the diaphragm 51 to vibrate, under the pulse signal, the diaphragm 51 only vibrates but does not make sound, and the diaphragm 51 vibrates to push the air in the front acoustic cavity 101 to convect with the air outside the speaker box 100, so that air cooling and heat dissipation are realized. The lower frequency pulse signal may be input separately when the speaker box 100 is not performing the task of playing sound, so that the speaker box 100 is only used for heat dissipation. While the speaker box 100 can play the audio task, the pulse signal with lower frequency can be superimposed into the music signal, and since the pulse signal is with ultra-low frequency, the pulse signal will not be heard by human ears, and the playing effect of the speaker box 100 will not be affected.
Specifically, when the diaphragm 51 vibrates in a direction approaching the top wall 11, relatively hot air introduced into the front acoustic cavity 101 by the heat conducting member 70 is discharged out of the speaker box 100, and when the diaphragm 51 vibrates in a direction away from the top wall 11, relatively cold air outside the speaker box 100 is sucked into the front acoustic cavity 101, so that a heat dissipation effect is achieved in a reciprocating manner.
Please refer to fig. 8. Meanwhile, the present invention also provides a mobile terminal 200, which comprises a housing 210 having a receiving space, a heat generating component 220 received in the housing 210, and the speaker box 100. The heat conducting member 70 of the speaker box 100 is connected to the heat generating member 220, heat generated by the heat generating member 220 is transmitted to the speaker box 100 through the heat conducting member 70, and the speaker box 100 performs air cooling and heat dissipation through vibration of the diaphragm 51.
The housing 210 is provided with a sound outlet 211, the sound outlet 211 is communicated with the sound guide channel 133, and the speaker box 100 emits sound through the sound outlet 211 and discharges hot air through the sound outlet 211 to the mobile terminal 200.
In the present embodiment, the heat generating component 220 is a cpu. Of course, in other embodiments, the heat generating component 220 may be a battery or any component of the mobile terminal 200 that requires heat dissipation.
It should be noted that in the present embodiment, the heat conducting member 70 is only connected to the cpu. Of course, in other embodiments, the heat conducting member 70 may be connected to a plurality of components requiring heat dissipation, such as a cpu, a battery, or any other components requiring heat dissipation, and the plurality of components requiring heat dissipation are dissipated through one speaker box 100.
Compared with the related art, the speaker box 100 of the present invention has the advantages that the heat conducting member 70 is arranged, and the heat conducting member 70 is utilized to guide the heat generated by the external heat generating components into the front acoustic cavity 101, so that the heat generating components can be radiated through the heat conducting member 70 due to the good heat radiation performance of the front acoustic cavity 101; by providing the output end 73 in a ring shape, the heat dissipation area of the heat conducting member 70 is increased, and the heat dissipation efficiency of the speaker box 100 is improved.
While the foregoing is directed to embodiments of the present invention, it will be understood by those skilled in the art that various changes may be made without departing from the spirit and scope of the invention.
