Example one

In order to solve the problems of scalding hands, aging and stuttering sound caused by overheating of the sound cavity of the conventional terminal, the present embodiment provides a sound cavity, please refer to fig. 2, and fig. 2 is a schematic diagram of the sound cavity according to the present invention. The sound cavity comprises a shell and a loudspeaker (not shown in the figure) arranged inside the shell; wherein, the shell material part or all of the shell is graphene plastic.

Specifically, the inventor discovers that the loudspeaker generates heat in a circuit during working, and along with the miniaturization development trend of the terminal, the sound cavity is increasingly miniaturized due to the influence of space, the heat conductivity coefficient of the shell material of the existing sound cavity is only 0.2W/mk, and the heat is easy to gather in the sound cavity, so that the temperature in the sound cavity is very high, the output power of the loudspeaker is limited, the service life and the tone quality of the loudspeaker are reduced, and the terminal is hot in hand and the sound is blocked, so that the use experience of a user is influenced. Furthermore, the low thermal conductivity of the sound chamber housing also causes non-uniform heat outside the speaker, which tends to collect at the speaker, and thus the local temperature at the speaker is high. Graphene plastic has better heat conductivity, and coefficient of heat conductivity can reach 5W/mk, and the more traditional sound chamber shell material of heat conductivity promotes 25 times, can transmit the heat to the sound chamber outside from sound intracavity portion fast to utilize outside air to carry out the extrinsic cycle, improved the radiating efficiency by a wide margin, thereby reduce the inside temperature in sound chamber. Therefore, the loudspeaker with the same size can apply higher power, the loudness and the tone quality of the loudspeaker are increased, and the service life of the loudspeaker can be prolonged under the same power. Furthermore, because graphite alkene plastics have better heat conductivity, can quick even heat, prevent the heat at the speaker heat source gathering to reduce the temperature of speaker heat source department. Fig. 2 is a schematic diagram of only one sound cavity, and the sound cavity described in this embodiment may also be a sound cavity with any other structure.

In one embodiment, the sound cavity further comprises a temperature sensor for detecting the temperature of the sound cavity, the temperature sensor is in communication connection with the speaker control unit, so that the speaker control unit adjusts the power of the speaker according to the temperature of the sound cavity detected by the temperature sensor, wherein the temperature sensor comprises a temperature acquisition end.

Specifically, through set up temperature sensor in the sound chamber, gather the operating temperature in sound chamber to give speaker the control unit with the operating temperature in this sound chamber, so that speaker control unit reduces when the operating temperature in this sound chamber reaches preset reference temperature the power of speaker realizes that the power of speaker is according to the operating temperature dynamic adjustment in sound chamber, avoids the terminal scald hand, ageing, the problem that the sound card is pause that leads to by the sound chamber is overheated.

In one embodiment, the temperature collection end is disposed within and/or on a surface of the housing material.

Specifically, the temperature acquisition end is arranged on the inner surface of the shell material facing the inside of the sound cavity and/or the outer surface facing the outside of the sound cavity. Therefore, the temperature of the sound cavity shell is detected more directly, the power of the loudspeaker is dynamically adjusted according to the temperature of the sound cavity shell, and the problems of scalding, aging and unsmooth sound of the terminal caused by overheating of the sound cavity are avoided. As can be understood by those skilled in the art, when the temperature acquisition end is arranged at different positions of the shell material, different temperature reference values can be correspondingly arranged.

Specifically, the temperature collection end is arranged inside the graphene plastic, on the inner surface facing the inside of the sound cavity and/or on the outer surface facing the outside of the sound cavity. Because graphite alkene plastics's coefficient of heat conductivity is high, so with the temperature acquisition end setting in graphite alkene plastics's inside and/or surface, can detect the temperature of sound chamber casing more accurately, realize the power of speaker according to the casing temperature dynamic adjustment in sound chamber, avoid the terminal scald hand, ageing, the problem of sound card pause that leads to by the overheated sound chamber.

In one embodiment, the loudspeaker comprises a coil, and the temperature acquisition end is arranged on the coil and/or in an inner space enclosed by the shell.

Specifically, when load data of the loudspeaker is increased, coil impedance can be correspondingly increased, and coil temperature can also be correspondingly increased, so that the temperature of the detection coil can correspond to the change of the detection coil impedance and the load data of the loudspeaker, and the temperature acquisition end is arranged on the coil, so that the current working temperature of the loudspeaker can be more directly detected, the dynamic adjustment of the power of the loudspeaker can be more quickly realized according to the working temperature of the loudspeaker, and the problems of scalding of the terminal, aging and unsmooth sound caused by the overheating of the loudspeaker are avoided. The temperature acquisition end is arranged in the inner space surrounded by the shell, the temperature of air in the sound cavity is detected, and the detection of the temperature of the sound cavity can be realized more conveniently.

As will be appreciated by those skilled in the art, the temperature collection tip may be disposed within the housing material, a surface of the housing material, on the coil, and/or within an interior space enclosed by the housing. Specifically, whether one or more of the above positions are provided with the temperature acquisition ends may be determined according to actual needs, and the number and the specific setting positions of the temperature acquisition ends are not limited in this embodiment.

In the above embodiment, the sound chamber includes a housing and a speaker disposed inside the housing; wherein, the shell material part or all of the shell is graphene plastic. Because graphene plastic's coefficient of heat conductivity is high, so the heat that speaker work produced can high-efficiently distribute to the sound chamber outside through the graphene plastic of sound chamber casing to improve the radiating efficiency in sound chamber, avoided the terminal scald hand, ageing, the unsmooth problem of sound that leads to by the sound chamber is overheated.

The power of the loudspeaker is dynamically adjusted according to the working temperature of the sound cavity, and the problems of scalding, aging and unsmooth sound of the terminal caused by overheating of the sound cavity are avoided.

The above steps will be described in detail with reference to the accompanying drawings and embodiments.

In step S301, the sound cavity temperature is detected.

Specifically, the terminal detects the temperature of the sound cavity to adjust the power of the loudspeaker according to the detected temperature of the sound cavity, and the problems of scalding, aging and unsmooth sound of the terminal caused by the fact that the loudspeaker still works at high power when the temperature of the sound cavity is too high are avoided. As can be understood by those skilled in the art, the terminal may periodically detect the sound cavity temperature, detect the sound cavity temperature in real time, start to detect the sound cavity temperature after the speaker works for a preset time period, and set a sound cavity temperature detection mode corresponding to the power of the speaker according to the power of the speaker, where the specific mode of detecting the sound cavity temperature by the terminal is not limited in this embodiment.

step S3011, detecting an internal temperature of the casing material of the sound cavity, a surface temperature of the casing material of the sound cavity, a coil temperature of the speaker, and/or an internal space temperature surrounded by the casing of the sound cavity.

Specifically, because the temperature collection ends of the temperature sensors may be disposed inside the casing material of the sound cavity, on the surface of the casing material, on the coil of the speaker and/or in the internal space enclosed by the casing of the sound cavity, the detection of the temperature of the sound cavity may be performed by detecting the internal temperature of the casing material of the sound cavity, the surface temperature of the casing material of the sound cavity, the coil temperature of the speaker and/or the internal space temperature enclosed by the casing of the sound cavity, that is, the temperature of the sound cavity is correspondingly detected according to the number and the positions of the temperature collection ends of the temperature sensors disposed in the sound cavity. The surface temperature of the shell material of the sound cavity can be correspondingly detected according to the inner surface of the shell material facing the interior of the sound cavity and/or the outer surface facing the exterior of the sound cavity, wherein the temperature acquisition end is arranged on the inner surface of the shell material facing the interior of the sound cavity and/or the outer surface of the shell material facing the exterior of the sound cavity.

Optionally, the detecting the internal temperature of the casing material of the sound cavity and/or the surface temperature of the casing material of the sound cavity comprises:

and detecting the internal and/or surface temperature of the graphene plastic.

Specifically, because the thermal conductivity coefficient of the graphene plastic is high, the temperature of the sound cavity shell can be accurately detected by detecting the internal and/or surface temperature of the graphene plastic, the power of the loudspeaker can be dynamically adjusted according to the shell temperature of the sound cavity, and the problems of hand scalding, aging and sound blockage of the terminal caused by overheating of the sound cavity are solved.

In step S302, when the temperature of the sound cavity reaches a preset temperature, the power of the speaker is reduced by a preset threshold.

Specifically, when the terminal detects that the temperature of the sound cavity reaches the preset temperature, the power of the loudspeaker is reduced by the preset threshold value, the power of the loudspeaker is dynamically adjusted according to the working temperature of the sound cavity, and the problems of scalding, aging and unsmooth sound of the terminal caused by overheating of the sound cavity are avoided. The values of the preset temperature and the preset threshold may be determined according to actual needs, and the specific values are not limited in this embodiment.

In one embodiment, referring to fig. 4, when the sound cavity temperature reaches the preset temperature, turning down the power of the speaker by the preset threshold includes:

step S3021, when the internal temperature of the shell material of the sound cavity reaches a first preset temperature, reducing the power of the speaker by a first preset threshold;

Specifically, when the temperature acquisition end of the temperature sensor is arranged at different positions of the sound cavity, different reference temperatures and corresponding speaker power adjustment values need to be set, for example, when the temperature acquisition end is arranged on a coil of the speaker, since the coil itself is a heat source, the third preset temperature can be set to be higher than the second preset threshold when the temperature acquisition end is arranged on the surface of the housing. The values of the first to fourth preset temperatures and the values of the first to fourth preset thresholds may be determined according to actual needs, and the specific values are not limited in this embodiment.

Optionally, when the internal temperature of the shell material of the sound cavity reaches a first preset temperature, the power of the loudspeaker is reduced by a first preset threshold; when the surface temperature of the casing material of the sound cavity reaches a second preset temperature, turning down the power of the speaker by a second preset threshold comprises:

when the internal temperature of the graphene plastic reaches a first preset temperature, reducing the power of the loudspeaker by a first preset threshold value; and when the surface temperature of the graphene plastic reaches a second preset temperature, reducing the power of the loudspeaker by a second preset threshold value.
