The embodiment of the application provides an electronic device, which can improve the stability of the electronic device for outputting sound signals.

An embodiment of the present application provides an electronic device, including:

the middle frame comprises an end part, the end part comprises a first side wall, and a first sound outlet and a second sound outlet are formed in the first side wall at intervals;

the camera assembly is a telescopic camera assembly and is arranged on the middle frame, at least part of the camera assembly is positioned between the first sound outlet and the second sound outlet, and the camera assembly can extend out of the first side wall or retract into the first side wall;

the first telephone receiver is arranged in the electronic equipment and is communicated with the first sound outlet;

and the second telephone receiver is arranged in the electronic equipment, and is communicated with the second sound outlet.

According to the electronic equipment provided by the embodiment of the application, as the two receivers are arranged in the electronic equipment, each receiver is respectively communicated with one sound outlet, and each sound outlet can transmit the sound signal generated by one receiver to the outside. When one sound outlet is blocked, the electronic equipment can also transmit sound signals to the outside through the other sound outlet, so that the electronic equipment is prevented from outputting sound to the outside. Furthermore, the two sound outlets are spaced from each other, so that the probability of both sound outlets being blocked simultaneously is small. Therefore, the situation that the electronic equipment cannot output sound to the outside because the receiver is blocked can be reduced, and the stability of the sound signal output by the electronic equipment is improved.

In some embodiments, referring to fig. 3, fig. 3 is a schematic diagram of a second structure of the electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 further includes a first receiver 21 and a second receiver 22. The first receiver 21 and the second receiver 22 are disposed at one end of the electronic device 100 at intervals, for example, at the top end of the electronic device 100 at intervals. Wherein, the top end is the end where the top of the electronic device 100 is located when displaying information. The first receiver 21 is installed inside the electronic device 100, and the second receiver 22 is also installed inside the electronic device 100.

For example, in some embodiments, the first receiver 21 may be mounted on the middle frame 13, so that the first receiver 21 is fixed by the middle frame 13. The second receiver 22 can also be mounted on the middle frame 13, so that the second receiver 22 can be fixed by the middle frame 13.

The first receiver 21 and the second receiver 22 may cooperate with each other at the same time, or may operate independently of each other. For example, when the first receiver 21 is jammed or malfunctions, the electronic apparatus 100 may generate a sound signal through the second receiver 22.

It is to be understood that in the description of the present application, the terms "first", "second", etc. are used merely for distinguishing between similar elements and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

Referring to fig. 4 and fig. 5 together, wherein fig. 4 is a schematic structural diagram of the middle frame 13 of the electronic device 100 shown in fig. 3, and fig. 5 is a schematic partial enlarged view of a region a in fig. 4.

Wherein the middle frame 13 includes an end portion 130. In some embodiments, the middle frame 13 may have a rectangular shape or a rounded rectangular shape, in which case the middle frame 13 includes long sides and short sides, and the end 130 is the end where the short sides of the middle frame 13 are located. For example, the end 130 may be the top end of the middle frame 13 when the middle frame 13 is vertically placed.

The end portion 130 is provided with a first sound outlet 132 and a second sound outlet 133 at an interval. The first sound outlet 132 and the second sound outlet 133 may be through holes disposed at the end 130 of the middle frame 13. The first sound outlet 132 and the second sound outlet 133 are used for transmitting sound signals generated in the electronic device 100 to the outside.

The first sound outlet 132 and the second sound outlet 133 may be through holes with shapes of round holes or square holes. In some embodiments, the first sound outlet 132 and the second sound outlet 133 are both circular holes, so that the sound signals transmitted to the outside by the electronic device 100 are more balanced.

The first receiver 21 is communicated with the first sound outlet 132, so that the first sound outlet 132 can transmit the sound signal generated by the first receiver 21 to the outside. The second receiver 22 is communicated with the second sound outlet 133, so that the second sound outlet 133 can transmit the sound signal generated by the second receiver 22 to the outside.

In the embodiment of the present application, since two receivers are disposed in the electronic device 100, each receiver is respectively communicated with one sound outlet, and each sound outlet can transmit a sound signal generated by one receiver to the outside. When one sound outlet is blocked, the electronic device 100 can also transmit a sound signal to the outside through the other sound outlet, so as to prevent the electronic device 100 from being unable to output sound to the outside. Furthermore, the two sound outlets are spaced from each other, so that the probability of both sound outlets being blocked simultaneously is small. Therefore, the situation that the electronic device 100 cannot output sound to the outside due to the blockage of the receiver can be reduced, and the stability of the sound signal output by the electronic device 100 can be improved.

In some embodiments, with continued reference to fig. 4 and 5, the end 130 of the middle frame 13 includes a first sidewall 131. Wherein the first sidewall 131 may be an outer sidewall of the end portion 130. The first sound outlet 132 may be formed on the first sidewall 131, and the second sound outlet 133 may also be formed on the first sidewall 131. For example, the first sound outlet 132 and the second sound outlet 133 may be formed on the first sidewall 131 by drilling.

Wherein the end 130 of the middle frame 13 comprises a second side wall 134 and a third side wall 135 arranged opposite to the second side wall 134.

For example, the second sidewall 134 may be a front surface of the middle frame 13, and the third sidewall 135 may be a rear surface of the middle frame 13, as shown in fig. 6. The front side is a side where a display screen of the electronic device 100 is located, and the back side is a side where a back cover of the electronic device 100 is located.

For another example, the second sidewall 134 can be a left side of the middle frame 13, and the third sidewall 135 can be a right side of the middle frame 13. The left side surface and the right side surface are planes where the left side surface and the right side surface of the display screen of the electronic device 100 are located.

Wherein the first sound outlet 132 is formed on the second sidewall 134, and the second sound outlet 133 is formed on the third sidewall 135.

Thus, the electronic apparatus 100 can simultaneously produce sound through the receivers located on both sides. For example, the electronic device 100 may sound through both the front and back sides simultaneously. Therefore, when a user answers a call, even if the electronic equipment is held reversely, namely, the surface where the rear cover is located is close to the ear, the user can also hear the sound.

The second receiver 22 is communicated with the second sound outlet 133 through the second sound guiding element 24, so that the sound signal generated by the second receiver 22 is guided out to the second sound outlet 133 through the second sound guiding element 24, and is transmitted to the outside through the second sound outlet 133.

In some embodiments, the first sound guiding element 23 and the second sound guiding element 24 may be a sound guiding tube, a sound guiding cavity, or the like.
