Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Referring to fig. 1, an electronic device 100 according to an embodiment of the invention includes a housing 20, and the housing 20 forms a sound cavity 22 and a sound outlet 24 communicating with the sound cavity 22. The electronic device 100 further comprises an electroacoustic element 30 and a temperature sensor 40, which are arranged in the sound cavity 22, wherein the temperature sensor 40 is used for acquiring a first temperature value in the sound cavity 22, and the first temperature value is used for judging whether the sound outlet 24 is blocked.

Referring to fig. 2, the temperature-based detection method according to the embodiment of the invention can be applied to an electronic device 100. The electronic device 100 includes a housing 20, the housing 20 forming a sound chamber 22 and a sound outlet 24 communicating with the sound chamber 22, the electronic device 100 further including an electroacoustic element 30 and a temperature sensor 40 disposed in the sound chamber 22. The detection method comprises the following steps:

s11: controlling the electroacoustic element 30 to sound;

s12: processing a first temperature value acquired by the temperature sensor 40 when the electroacoustic element 30 sounds;

s13: judging whether the first temperature value is greater than a preset threshold value or not; and

s14: and judging that the sound hole 24 is blocked when the first temperature value is greater than a preset threshold value.

The electronic device 100 and the detection method of the embodiment of the invention judge whether the sound outlet 24 is blocked by detecting the temperature value through the temperature sensor 40, thereby accurately judging whether the electroacoustic element 30 can work normally and enabling a user to dredge the sound outlet 24 to ensure that the sound outlet 24 is not blocked.

Specifically, the electronic device 100 of the embodiment of the present invention can be used to implement the detection method of the embodiment of the present invention.

In some embodiments, the electronic device 100 comprises a cell phone, a tablet, a smart watch, a laptop, a smart band, or a smart helmet. In an example of the present invention, the electronic device 100 is a cellular phone.

In some embodiments, the electro-acoustic element 30 comprises a speaker, an earphone, a loudspeaker, or other device capable of converting an electrical signal to an acoustic signal, and may be disposed, for example, at the bottom end of the electronic device 100. In the present embodiment, the electroacoustic element 30 is a moving coil speaker. In other embodiments, the electroacoustic element 30 may be disposed at other suitable locations of the electronic device 100. Even more, the electroacoustic element 30 may be included in a plurality, adjacently disposed or separately disposed at different positions of the electronic device 100.

In some embodiments, the acquired temperature value may be the measurement value of the temperature sensor 40 or the difference between two measurement values of the temperature sensor 40, without any limitation.

In some embodiments, the temperature sensor 40 is used to acquire a first temperature value within the acoustic chamber 22 while the electroacoustic element 30 is sounding.

It can be understood that the sound chamber 22 is in communication with the outside when the sound outlet 24 is not blocked, and the heat generated by the electroacoustic element 30 is easily conducted to the outside when the electroacoustic element 30 is operated, so that the temperature value obtained from the temperature sensor 40 is low and changes slowly and is less than or equal to the predetermined threshold value; when the sound outlet 24 is blocked and the electroacoustic component 30 is in operation, the heat exchange between the sound chamber 22 and the outside is reduced due to the blockage of the sound outlet 24, and the heat generated by the electroacoustic component 30 is dissipated slowly, so that the temperature value obtained by the temperature sensor 40 is higher and changes faster, and is likely to be greater than the predetermined threshold value.

Therefore, it is determined that the sound hole 24 is blocked when the first temperature value is greater than the predetermined threshold value, and it is determined that the sound hole 24 is unblocked when the first temperature value is less than or equal to the predetermined threshold value.

Referring again to fig. 1, in some embodiments, the sound chamber 22 includes a front sound chamber 222 and a rear sound chamber 224, the front sound chamber 222 connects the rear sound chamber 224 and the sound outlet 24, the temperature sensor 40 is disposed in the front sound chamber 222 or the rear sound chamber 224, and the electroacoustic element 30 is disposed in the rear sound chamber 224.

In this way, the temperature value in the sound cavity 22 can be obtained by measuring with the temperature sensor 40, and since the electroacoustic element 30 is disposed in the back sound cavity 224, the temperature change of the back sound cavity is more obvious, and the temperature sensor 40 disposed in the back sound cavity 224 can detect the change of the temperature value more quickly and sensitively, thereby determining whether the sound outlet 24 is blocked.

In some embodiments, the temperature sensor 40 may also be disposed at other locations in the sound chamber 22, such as in the front sound chamber 222, while the electroacoustic element 30 is disposed in the rear sound chamber 224.

Referring again to fig. 1, in some embodiments, the cross-sectional area of the front sound cavity 222 near the sound outlet 24 is greater than the cross-sectional area of the front sound cavity 222 near the back sound cavity 224.

Thus, the area of the sound outlet hole 24 can be increased, and the sound output range of the electroacoustic element 30 can be increased.

Referring to fig. 3, in some embodiments, step S11 includes the following steps:

s112: the electro-acoustic element 30 is controlled to play a predetermined audio frequency for a predetermined time.

Thus, when the sound outlet 24 is blocked, the temperature value can be obviously changed, and whether the sound outlet 24 is blocked or not can be judged more accurately.

It is understood that the heating of the electroacoustic component 30 during operation is the main factor causing the temperature variation, and the longer the operation time is, the more heat is accumulated, and the larger the temperature value variation is. By playing a predetermined audio frequency for a predetermined time, it is possible to provide the electroacoustic element 30 with a sufficient heat accumulation time to obtain a more significant temperature value change in the case where the sound outlet hole 24 is blocked. Meanwhile, the predetermined audio frequency lasting for the predetermined time is played, and the size of the temperature value obtained from the temperature sensor 40 can be known in advance under the condition that the sound outlet 24 is not blocked, and the maximum temperature value can be taken as the predetermined threshold value.

Referring to fig. 4, in some embodiments, the detection method includes the following steps:

s15: when the sound outlet hole 24 is not blocked, the electroacoustic element 30 is controlled to sound; and

s16: the second temperature value acquired by the temperature sensor 40 when the electroacoustic element 30 is sounded when the sound outlet hole 24 is not clogged is processed as the predetermined threshold value.

In this way, the second temperature value at which the sound outlet holes 24 are not clogged can be obtained as the predetermined threshold value. Specifically, in one example, the condition that the sound outlet 24 is not blocked may be determined by the condition that is determined when the electronic device 100 is shipped from the factory, or determined when the user has cleaned the sound outlet 24.

Referring to fig. 5, in some embodiments, the detection method includes the following steps:

s17: when it is judged that the sound hole 24 is clogged, a prompt message is generated.

In this way, the user can be prompted in time when the sound outlet 24 is blocked so as to facilitate the user to dredge the sound outlet 24.

Specifically, the prompt information may be voice information, text information, or the like. For example, the electronic device 100 includes a plurality of electroacoustic elements 30, and when a sound outlet of one of the electroacoustic elements 30 is blocked, the other electroacoustic element is used to play sound information; for another example, the text information of "abnormal playing sound" is displayed on the display screen, so that the user can timely and accurately grasp the information of the electroacoustic component 30, and the intellectualization and humanization of the electronic device 100 are further improved.

Referring to fig. 6, the electronic device 100 according to the embodiment of the invention further includes a circuit board 50, a processor 60, a memory 70, and a power circuit 80. Wherein the circuit board 50 is disposed inside the space enclosed by the housing 20, the processor 60 and the memory 70 are disposed on the circuit board 50, and the power circuit 80 is used for supplying power to each circuit or device of the electronic device 100.

The memory 70 is used to store executable program code. The processor 60 runs a program corresponding to the executable program code by reading the executable program code stored in the memory 70 for performing the detection method of the above-described embodiment. The processor 60 is configured to perform the following steps:

controlling the electroacoustic element 30 to sound;

processing a first temperature value acquired by the temperature sensor 40 when the electroacoustic element 30 sounds;

judging whether the first temperature value is greater than a preset threshold value or not; and

and judging that the sound hole 24 is blocked when the first temperature value is greater than a preset threshold value.
