The speaker box 200 includes a housing 201 having a first receiving space, and a sound generating unit 202 received in the first receiving space, wherein a sound guiding channel 203 is formed in the housing 201, and a sound outlet 204 is formed at a position of the housing 201 corresponding to the sound guiding channel 203.

The sound generating unit 202 includes a diaphragm 2021 for generating sound by vibration, the diaphragm 2021 divides the first accommodating space into a front sound cavity 205 and a rear cavity (not shown), that is, the diaphragm 2021 and the casing 201 form the front sound cavity 205 at an interval, the sound guiding channel 203 communicates the front sound cavity 205 with the outside through the sound outlet hole 204, the sound guiding channel 203 and the front sound cavity 205 form a front cavity 210 together, and the front cavity 210 serves as a side sound generating structure of the speaker box 200.

The heat pipe 400 connects the speaker box 200 and the heat source device 300 to conduct heat generated from the heat source device 300 during operation to the speaker box 200.

Specifically, the heat pipe 400 includes a condensation end 1a, an evaporation end 2a, and a conduction portion 3 a.

The condensation end 1a is fixed to the housing 201 and connected to the front cavity 210, the evaporation end 2a is connected to the heat source device 300, and the conduction part 3a connects the condensation end 1a and the evaporation end 2 a. Preferably, the condensation end 1a and the housing 201 are integrally formed by injection molding.

Further, the condensation end 1a includes a first section 101a and a second section 102a, the first section 101a is disposed in the front sound cavity 205 and connected to the conductive part 3a, and the second section 102a is disposed in the sound guide channel 203 and on a side of the first section 101a away from the conductive part 3 a.

Specifically, the volume of the front acoustic chamber 205 changes when the diaphragm 2021 vibrates: when the volume of the front sound cavity 205 becomes smaller, the diaphragm 2021 discharges part of the air in the front sound cavity 205 to the outside through the sound outlet hole 204; when the volume of the front acoustic cavity 205 becomes larger, the diaphragm 2021 sucks the external space into the front acoustic cavity 205 through the sound outlet hole 204; the above process causes the air in the front acoustic chamber 205 to be convected with the air in the outside. The vibration of the diaphragm 2021 causes the heat in the front acoustic cavity 205 to be dissipated out of the housing 201 along with the circulation of air, thereby achieving the heat dissipation of the heat source device 300, and making the heat dissipation effect of the speaker apparatus 100 good; meanwhile, since the condensation end 1a is connected to the heat conducting portion 521 through the second segment 102a, that is, the condensation end 1a can directly conduct heat to the heat conducting member 52 in a heat conduction manner and radiate the heat outwards through the heat conducting member 52, the heat radiation area is effectively increased, and the heat radiation effect is optimized. With the structure, the condensation end 1a is close to one side of the front cavity 210 and radiates heat in a heat radiation and heat conduction mode, so that the heat radiation efficiency is improved, and the heat radiation performance of the loudspeaker device 100 is optimized.

Further, the heat conducting portion 521 includes a first heat conducting plate 5211 sandwiched between the side of the supporting member 51 close to the front cavity 210 and the casing 201, and a second heat conducting plate 5212 extending from the edge of the first heat conducting plate 5211 along the outside of the supporting member and bending in a direction away from the casing 201; the first heat conduction plate 5211 abuts against the housing 201 and covers the sound outlet 204, the second section 102a extends to the outside of the housing 201 and is connected to the first heat conduction plate 5211, and the extension wall 522 extends from the first heat conduction plate 5211 in a direction close to the through hole 510.

It should be noted that the first heat conduction plate 5211 and the second heat conduction plate 5212 are separate structures; of course, in order to facilitate the assembly of the heat conducting member, the first heat conducting plate and the second heat conducting plate may be integrally formed.

Preferably, in order to improve the reliability of assembling the sound emitting assembly 500, the supporting member 51 and the heat conducting member 52 are integrally formed.

Furthermore, the diameter of the sound guiding hole 520 is smaller than the diameter of the sound outlet hole 204, so that the air flow velocity in the sound guiding hole 520 is larger, the degree of turbulence of the flow is larger, the heat exchange coefficient between the heat pipe 400 and the air is effectively improved, and the heat dissipation performance of the speaker device 100 is further improved.

It should be mentioned that the extension wall 522 includes at least two and is arranged at intervals, the sound guide holes 520 are arranged in one-to-one correspondence with the extension wall 522, and each sound guide hole 520 is opposite to and communicated with the sound outlet 204.

It should be noted that the vibration of the diaphragm 2021 may be in a sound-emitting form or a non-sound-emitting form, and the heat conducted into the front sound cavity 205 may be dissipated to the outside along with the air circulation. So that the speaker box 200 can exclusively perform the work of dissipating heat.

Specifically, a pulse signal of a lower frequency is input to the speaker box 200, and a low frequency sound generated in the speaker box 200 is not heard by human ears. In this embodiment, the input lower frequency is below 1000 Hz. In a specific application, the speaker box 200 may play the pulse signal alone when not performing a music playing task; the loudspeaker enclosure 200 may also superimpose the pulse signal into the music signal while performing the music playing task.

In the present embodiment, the heat source device 300 is any one of a processor and a battery, and may be specifically configured according to actual situations.

It should be noted that the structural form of the heat pipe 400 is not limited, and it may be a solid heat pipe structure made of a solid heat conductive metal material; also can be for inside be equipped with the passageway and the passageway intussuseption is filled with the liquid cooling tube structure of heat transfer medium, and the inside passageway of this liquid cooling tube structure is mostly the equivalent diameter.

And the liquid cooling pipe combines the speaker device that forms with the speaker case at the heat dissipation in-process, and the higher heat flux density of heat source is comparatively equitable between with the high-efficient heat transfer coefficient of heat transfer working medium, and after heat conducts the heat transfer working medium rapidly, efficient heat transfer efficiency requires that the heat transfer working medium condenses and evaporates rapidly, the promotion on its heat transfer coefficient order of magnitude that the phase transition of heat transfer working medium caused in the twinkling of an eye. The phase change will inevitably cause the change of the volume of the heat exchange working medium, the volume is reduced during condensation, and the volume is increased during evaporation.

However, as the equivalent diameters of the channels in the liquid cooling pipes are the same, the turbulence effect is greatly reduced at the condensation end during the change of the physical state of the heat exchange working medium, so that the heat exchange effect is limited, heat exchange is carried out between the condensation end of the heat pipe and the outside air, the heat transfer effect of the air is limited, the heat exchange is not uniform between the condensation end and the evaporation end, and the overall heat exchange performance is limited by the final lower heat exchange effect of the air.

Foretell solid heat pipe structure is limited with the heat transfer effect that is equipped with the also liquid cooling tube structure of passageway, here, for further optimizing speaker device's heat dispersion, more excellent, the utility model discloses a heat pipe 400 is the different heat pipe structure of the equivalent weight diameter of each inner passage preferably, and is concrete:

referring to fig. 5-6, the present invention provides a heat pipe 400, including: condensation end 1a, evaporation end 2a, conduction part 3a and heat exchange working medium (not shown).

Preferably, the condensation end 1a, the evaporation end 2a, and the conduction part 3a are formed in an integral structure.

The condensing end 1a is provided with a plurality of condensing channels 11a therein, and each condensing channel 11a includes a condensing inlet end 111a and a condensing outlet end 112 a.

A plurality of evaporation flow channels 21a are arranged in the evaporation end 2a, the evaporation flow channels 21a are sequentially communicated end to form an evaporation flow channel unit 20a, and the evaporation flow channel unit 20a comprises an evaporation inlet end 201a and an evaporation outlet end 202 a.

In the present embodiment, the plurality of evaporation flow channels 21a are arranged in parallel to each other to increase the length of the path of the evaporation flow channel unit 20a in the space having the same volume, thereby improving the heat transfer effect.

The two ends of the conduction part 3a are respectively connected with the condensation end 1a and the evaporation end 2a, and are used for transferring the heat of the evaporation end 2a to the condensation end 1 a.

The conduction part 3a is provided therein with a first conduction flow path 31a and a second conduction flow path 32 a.

The condensation outlet end 112a of the condensation flow channel 11a is communicated with the head end 311a of the first flow channel 31a, the evaporation inlet end 201a of the evaporation flow channel unit 20a is communicated with the tail end 312a of the first flow channel 31a, and the equivalent diameter of the first flow channel 31a gradually decreases from the head end 311a to the tail end 312 a.

Both ends of the second conduction flow path 32a communicate with the condensation inlet end 111a and the evaporation outlet end 202a, respectively.

The heat exchange working medium is filled in the heat pipe 400 for transferring heat. The heat exchange working medium exchanges heat with air at the condensation end 1a of the heat pipe 400, the gaseous heat exchange working medium is changed into liquid, the volume is reduced, and the gaseous heat exchange working medium flows back to the evaporation end 2a under the pushing of the evaporation pressure of the evaporation end 2 a; the liquid heat exchange working medium absorbs heat from heat sources such as processors, evaporates into a gas state and flows to the condensation end 1a, so as to form a circulation, that is, the liquid heat exchange working medium circularly flows in the evaporation flow channel 21a, the second conduction flow channel 32a, the condensation flow channel 11a and the first conduction flow channel 31a, thereby realizing heat dissipation of the heat sources.

The equivalent diameter of the first transfer channel 31a is gradually reduced from the head end 311a to the tail end 312a, and the arrangement enables the first transfer channel 31a to form a channel structure with gradually-changed equivalent diameter at the two ends of the condensation end 1a and the evaporation end 2a, so that the flow speed of the liquid heat exchange working medium at the condensation end 1a is increased, the degree of flow flocculation is enhanced, and the exchange of substances in the heat exchange working medium is severe; meanwhile, the degree of flocculation is improved, the thickness of a boundary layer for heat exchange is greatly reduced, the thermal resistance is further reduced, and the heat transfer effect is effectively improved by combining the two aspects.

Preferably, in the present embodiment, the plurality of condensing flow channels 11a are uniformly arranged; the equivalent diameters of the plurality of evaporation flow channels 21a increase in order from the evaporation inlet end 201a toward the evaporation outlet end 202a (the direction in which the heat exchange medium flows). The equivalent diameter of the same evaporation flow channel 21a is a fixed value.

It should be noted that, it is also possible that the equivalent diameter of the same evaporation flow channel 21a is increased in the direction from the evaporation inlet end 201a to the evaporation outlet end 202a of the evaporation flow channel unit 20a (the direction in which the heat exchange medium flows).

In this structural setting, because of the even middling pressure dispersion in condensation runner 11a of gaseous state heat transfer working medium of condensation end 1a, consequently, condensation runner 11a evenly spreads the setting, and is carrying out the heat exchange in-process more evenly with the outside air, and the radiating effect is stable.

The evaporation ends 2a are different, when the heat exchange working medium is liquefied by the condensation end 1a and flows back to the evaporation end 2a through the first flow guide channel, the equivalent diameter at the evaporation inlet end 201a is reduced rapidly compared with that at the condensation outlet end 112a, at the moment, the flow velocity of the liquid heat exchange working medium is increased, the flow flocculation degree is enhanced, and the exchange of substances in the heat exchange working medium is severe; meanwhile, the degree of flocculation is improved, the thickness of a boundary layer for heat exchange is greatly reduced, the thermal resistance is further reduced, and the heat transfer effect is effectively improved by combining the two aspects. Meanwhile, the above structural design of the evaporation flow channel 21a can provide an expansion space for the heat exchange working medium when the heat exchange working medium is evaporated into gas, so that the flow rate of the heat exchange working medium is uniform, the pressure is average, and the heat exchange with a heat source is quicker and more stable.

In this embodiment, the equivalent diameter of the tail end 312a of the first flow guiding channel 31a is the same as the equivalent diameter of the evaporation flow channel 21a communicated with the tail end 312a, or at least not larger than the equivalent diameter of the evaporation flow channel 21a communicated with the tail end 312a, so as to avoid increasing the flow resistance of the heat exchange medium and improve the transfer effect.

A sound port (not shown) is formed through the housing 602 at a position corresponding to the sound guide hole 520, and the sound port is in air communication with the front cavity 210 through the sound guide hole 520, so that heat conducted from the heat source device 300 to the front cavity 210 through the heat pipe 400 is dissipated to the outside of the housing 602.

In the present embodiment, the application of the speaker box 100 to the mobile terminal 600 effectively optimizes the heat dissipation performance of the mobile terminal 600.

More preferably, the heat conducting portion 521 at least partially abuts against the housing 602, specifically, the housing 602 includes a bottom wall 6021 and an extending wall 6022 bent and extended from the bottom wall 6021, and the second heat conducting plate 5212 abuts against the side wall 6022, that is, heat can be directly conducted to the side wall 6022 through the second heat conducting plate 5212 to achieve heat dissipation, and this arrangement effectively increases the heat dissipation area, so that the heat dissipation performance of the mobile terminal 600 is better.
