[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a speaker box apparatus 100 and a mobile terminal 200 using the speaker box apparatus 100.
The speaker box 1 includes a housing 11 having a first receiving space 10, a sound generating unit 12 mounted in the first receiving space 10, and a heat conductive cover 13.
The housing 11 is provided with a through hole 1101 and a sound guide channel 1102 penetrating through the housing, and the through hole 1101 and the sound guide channel 1102 are spaced from each other.
The housing 11 includes an upper cover 111 and a lower cover 112 covering the upper cover 111, and the upper cover 111 and the lower cover 112 together enclose a first accommodating space 10; the through hole 1101 and the sound guide channel 1102 are both disposed at the upper cover 111 in a spaced manner.
The sounding unit 12 includes a diaphragm 121 for vibrating and sounding, and the diaphragm 121 divides the casing 11 into a front sound cavity 101 and a rear cavity 102. The sound guide channel 1102 is communicated with the outside and forms a front cavity 110 with the front sound cavity 101 for lateral sound production; the through hole 1101 communicates with the front chamber 101.
The heat-conducting cover plate 13 is made of a material with good heat-conducting property, such as a copper sheet, a steel sheet, and the like. The heat conducting cover plate 13 covers the through hole 1101, and at least a part of the orthographic projection of the vibrating diaphragm 121 along the vibration direction of the vibrating diaphragm 121 falls on the vibrating diaphragm 121, that is, the heat conducting cover plate 13 is opposite to or partially opposite to the vibrating diaphragm 121.
Specifically, the lower cover 112, the upper cover 111 and the diaphragm 121 together enclose the rear cavity 102; the heat conducting cover plate 13, the diaphragm 121 and the upper cover 111 together enclose the front acoustic cavity 101.
The heat source 2 is capable of generating heat, and is an electronic component mounted on the mobile terminal 200, and generates a large amount of heat in the working process of the mobile terminal 200, such as a processor, a battery, a sensor, or the like.
The heat conducting member 3 is a hollow integrally formed structure, and is filled with a heat conducting medium, such as heat conducting silicone grease, cooling liquid, and the like, and includes a first end 31, a second end 32, and a connecting portion 33 connecting the first end 31 and the second end 32. The first end 31 is attached to the heat conducting cover plate 13 and far away from one side of the upper cover, and the second end 32 and the first end 31 are arranged at intervals and attached to the heat source 2.
The thermal retardation block 4 is made of a material capable of storing heat and having a large specific heat capacity, such as lithium 3582, and in this embodiment, the thermal retardation block 4 is made of lithium 3582 for storing and releasing heat. The thermal hysteresis block 4 is fixed to the heat conductive member 3, specifically, to the connecting portion 33.
When the heat source 2 works at a high power and the heat dissipation efficiency of the loudspeaker box 1 is not enough to dissipate heat and cool down in time, the heat conducting piece 3 conducts part of heat generated by the heat source to the thermal hysteresis block 4 for temporary storage, when the heat source 2 works at a low power, the heat dissipation is less, at the moment, the thermal hysteresis block 4 conducts the stored heat to the loudspeaker box 1 through the heat conducting piece 3, and then the convection heat dissipation is realized through the loudspeaker box 1.
Specifically, the heat generated by the heat source 2 is partially conducted to the second end 32 and then finally conducted to the first end 31 through the connection portion 33. The first end 31 conducts heat to the front acoustic cavity 101 through the heat conductive cover 13 and the through hole 1101, and the diaphragm 121 vibrates to push air inside the front acoustic cavity 101 and then circulates with the outside through the sound conduction channel 1102, so as to radiate heat to the outside of the housing 11. When the diaphragm 121 vibrates to make the front acoustic cavity 101 become small in volume, the diaphragm 121 exhausts a part of air in the front acoustic cavity 101 to the outside through the sound guide channel 1102; when the volume of the front sound cavity 101 becomes larger, the external air is sucked into the front sound cavity 101 through the sound guide channel 1102, so that convection between the front sound cavity 101 and the external air is realized, and heat is dissipated to the outside of the shell 11 along with the convection of the air, so that partial heat dissipation is realized.
The vibration of the diaphragm 121 may be in a sound-emitting form or a non-sound-emitting form, and both the vibration and the non-sound-emitting form can radiate heat conducted to the front sound cavity 101 to the outside along with air, so that the speaker box 1 can exclusively perform a heat radiation work. For example, when a low frequency lower than 1000Hz is input to the speaker box 1, the low frequency sound generated in the speaker box 1 is not heard by human ears. In a specific application, the loudspeaker box 1 can play the pulse signal independently when not executing a music playing task; the loudspeaker enclosure 1 may also superimpose the pulse signal into the music signal when performing a music playing task. Because the signal is an ultra-low frequency pulse signal, the signal can not be heard by human ears and the normal listening effect is not influenced.
When the heat source 2 works at high power, more heat is generated, and all heat cannot be dissipated out of the shell immediately through the heat dissipation mode; part of heat generated by the heat source 2 is conducted to the connecting part 33 through the second end 32, and the thermal hysteresis block 4 is fixedly connected with the connecting part 33, so that heat which cannot be conducted to the loudspeaker box 1 in time is stored, and the rapid cooling of the heat source 2 is realized.
In this embodiment, the thermal retardation block 4 is a solid structure, made of lithium 3582, and is in fixed contact with one end of the connecting portion 33 close to the heat source 2; specifically, the connecting portion 33 penetrates through the whole thermal retardation block 4, so that the contact area between the thermal retardation block 4 and the connecting portion 33 is maximized, which is beneficial to timely conducting heat to the thermal retardation block 4, and further storing heat, thereby realizing rapid cooling of the heat source 2.
When the working power of the heat source 2 is small, that is, the amount of heat emitted is small, the connecting portion 33 conducts the heat stored in the thermal hysteresis block 3 and the heat generated by the heat source 2 to the first end 31, and the first end 31 conducts the heat to the heat-conducting cover plate 13; the heat-conducting cover plate 13 is opposite to or partially opposite to the diaphragm 121, and the structure enables the part of the heat-conducting cover plate 13 corresponding to the diaphragm 121 to be in high-speed airflow; when the vibrating diaphragm 121 vibrates to push air to flow, the heat conducting cover plate 13 conducts heat to the front sound cavity 101, and the front sound cavity 101 is communicated with the outside through the sound conducting channel 1102, so that the heat is radiated to the outside of the shell 11.
Preferably, the structure of the first end 31 is not limited, for example, in the present embodiment, the first end 31 has a rectangular shape; the orthographic projection of the first end 31 to the heat-conducting cover plate 13 along the vibration direction of the diaphragm 121 completely falls on the heat-conducting cover plate 13, so as to ensure the heat dissipation area between the first end 31 and the heat-conducting cover plate 13, thereby ensuring the reliability of heat dissipation; and the width of the first end 31 is greater than that of the connecting part 33, so that the contact area between the first end and the heat-conducting cover plate 13 is increased, and the heat dissipation efficiency is improved.
In this embodiment, the heat conducting member 3, the thermal hysteresis block 4 and the heat conducting cover plate 13 are integrally formed, so that the problem of the heat conducting cover plate 13 and the thermal hysteresis block 4 falling off is avoided, the thermal hysteresis 4 and the heat conducting member 3 are better fixed, the heat conducting cover plate 13 and the heat conducting member 3 are better fixed, and the stability of the speaker box device 100 in the heat dissipation process is improved.
Please refer to fig. 1-7, the mobile terminal 200 of the present invention includes a housing 6, a screen 5 covering the housing 6 and forming a second receiving space 60, and the speaker box device 100 of the present invention.
The speaker box device 100 is disposed in the second receiving space 60, the housing 6 is disposed with a sound outlet 61 penetrating through the housing 6, the sound outlet is in air communication with the sound guide channel 1102, and further communicates the front sound cavity 101 with the outside, so as to form a side heat dissipation structure of the mobile terminal 200.
The heat emitted by the heat source 2 and the heat stored in the thermal hysteresis block 4 or the heat emitted by one of the two structures is conducted to the heat-conducting cover plate 13 through the heat-conducting member 3; the heat conducting cover plate 13 conducts heat to the front acoustic cavity 101; when the diaphragm 121 vibrates, the heat of the front acoustic cavity 101 is dissipated to the outside through the sound guide channel 1102 and the sound outlet 61, so that a heat dissipation effect is achieved, and the heat dissipation effect of the mobile terminal 200 is better.
