Abstract

The utility model discloses electronic equipment, and belongs to the technical field of audio. The electronic equipment comprises a shell, a first function panel, a second function panel and a loudspeaker module. The audio frequency emitted by the first vibration cavity in the loudspeaker module can be propagated through the first sound output channel, the second sound output channel and the first sound output gap in sequence, and the audio frequency output by the second vibration cavity can be propagated through the second sound output gap. Therefore, in the process that a user answers a call or answers voice information by using the electronic equipment, no matter whether the electronic equipment is in a folded state or an unfolded state, the sound emitted by the loudspeaker module can be better conducted to the ears of the user.

[0049] For a clearer description of the structure of the electronic device, reference can be made to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of the electronic device in an unfolded state, and Figure 2is a structural schematic diagram of an electronic device in a folded state provided by an embodiment of the present application. The electronic device 000 can include a housing 100, a first functional panel 200, a second functional panel 300, and a loudspeaker module 400. Figure 1 and Figure 2 not shown in the figure).

[0050] Please refer to Figure 3 , Figure 3 is a partial structural schematic diagram of an electronic device provided by an embodiment of the present application. In the electronic device 000, the first functional panel 200 and the second functional panel 300 are respectively connected to the housing 100 on both sides of the housing 100.

[0051] Here, when the electronic device 000 is a foldable display device, one of the first functional panel 200 and the second functional panel 300 can be a foldable display screen, which can serve as the main display screen of the electronic device 000; the other of the first functional panel 200 and the second functional panel 300 can be a non-foldable display screen, which can serve as the auxiliary display screen of the electronic device 000. It should be noted that the present application is illustratively described by taking the first functional panel 200 as the auxiliary display screen and the second functional panel 300 as the main display screen, i.e., the first functional panel 200 is a non-foldable display screen and the second functional panel 300 is a foldable display screen.

[0052] In this case, the housing 100 in the electronic device 000 can include a first casing 110 and a second casing 120, and a hinge 130 for connecting the first casing 110 and the second casing 120.

[0053] The loudspeaker module 400 in the electronic device 000 is fixed inside the housing 100. The loudspeaker module 400 has a first vibration cavity A1 and a second vibration cavity A2 arranged opposite to each other, and a first sound outlet channel C1 in communication with the first vibration cavity A1. Here, the loudspeaker module 400 can emit sound through the first vibration cavity A1 and the second vibration cavity A2, and the first sound outlet channel C1 can be used to propagate the audio output in the first vibration cavity A1.

[0054] The outer edge of the first functional panel 200 in the electronic device 000 has a first sound outlet gap M1 with the housing 100, and the housing 100 in the electronic device 000 has a second sound outlet channel C2 for communicating the first sound outlet channel C1 and the first sound outlet gap M1.

[0055] The housing 100 in the electronic device 000 has a second sound outlet gap M2 communicating with the second vibration cavity A2 towards the side of the second functional panel 300. In this way, the audio output in the second vibration cavity A2 can be transmitted through the second sound outlet gap M2.

[0056] It should be noted that the loudspeaker module 400 in the present application can be used as a receiver in the electronic device 000.

Therefore, when the electronic device 000 is in an unfolded state and the user holds the electronic device 000 to receive a phone call or voice information, the second functional panel 300 can face the user's face, and in this state, the end of the second sound outlet gap M2 away from the second vibration cavity A2 can be close to the user's ear, so that the sound emitted by the loudspeaker module 400 through the second vibration cavity A2 can be conducted to the user's ear through the second sound outlet gap M2, so that the user can receive a phone call or voice information through the electronic device 000 in the unfolded state.

[0058] When the electronic device 000 is in a folded state and the user holds the electronic device 000 to receive a phone call or voice information, the first functional panel 200 can face the user's face, and in this state, the first sound outlet gap M1 can be close to the user's ear, so that the sound emitted by the loudspeaker module 400 through the first vibration cavity A1 can be transmitted to the user's ear through the first sound outlet channel C1, the second sound outlet channel C2 and the first sound outlet gap M1 in sequence, so that the user can receive a phone call or voice information through the electronic device 000 in the folded state.

[0059] In this way, during the process that the user uses the electronic device 000 to answer a call or listen to voice information, the sound emitted by the loudspeaker module 400 can be better conducted to the user's ear, regardless of whether the electronic device 000 is in a folded state or an unfolded state. In this way, the same loudspeaker module 400 can be used to conduct sound to the user's ear when the electronic device 000 is in a folded state or when the electronic device 000 is in an unfolded state, without increasing the number of loudspeaker modules 400 in the electronic device 000, thereby meeting the sound requirements in different use scenarios. In addition, since the loudspeaker module 400 does not need to be additionally arranged, the space of the electronic device 000 is saved, thereby improving the utilization rate of the internal space of the electronic device 000.

[0060] In summary, the electronic device provided in the embodiments of the present application includes a housing, a first functional panel, a second functional panel, and a loudspeaker module. The audio emitted by the first vibration cavity in the loudspeaker module can be sequentially propagated through the first sound outlet channel, the second sound outlet channel, and the first sound outlet gap, and the audio output in the second vibration cavity can be propagated through the second sound outlet gap. Therefore, during the process that the user uses the electronic device to answer a call or listen to voice information, the sound emitted by the loudspeaker module can be better conducted to the user's ear, regardless of whether the electronic device is in a folded state or an unfolded state. In this way, the same loudspeaker module 400 can be used to conduct sound to the user's ear when the electronic device 000 is in a folded state or when the electronic device 000 is in an unfolded state, without increasing the number of loudspeaker modules 400 in the electronic device 000, thereby meeting the sound requirements in different use scenarios. In addition, since the loudspeaker module 400 does not need to be additionally arranged, the space of the electronic device 000 is saved, thereby improving the utilization rate of the internal space of the electronic device 000.

The seal 403 is located between the abutting portion 404 and the loudspeaker support 402 and abuts the loudspeaker support 402 and the abutting portion 404, respectively. In this way, the dust and moisture that intrudes from the first sound outlet gap M1 between the outer edge of the first functional panel 200 and the shell 100 of the electronic device 000 can be blocked by the seal 403 in the loudspeaker module 400, so that these dust and moisture cannot intrude into the loudspeaker body 401 in the loudspeaker module 400 through the first sound outlet channel C1, thereby reducing the risk of damage to the loudspeaker module 400 due to the entry of dust and moisture.

Here, the sound emitted in the second vibration cavity A2 can be blocked by the sound blocking plate 500, so that the sound emitted by the sound blocking plate 500 will not have the problem of sound leakage due to conduction to the second functional panel 300, thereby making the sound blocked by the sound blocking plate 500 can only be conducted to the outside through the third sound outlet gap M3 and the second sound outlet gap M2 in turn.

[0076] In the embodiment of the present application, as shown in Figure 4 and Figure 10 , the electronic device 000 can further include a sealing strip 600.

[0077] In the present application, the sealing strip 600 surrounds the second vibration cavity A2 having the third sound outlet gap M3 between the sound blocking plate 500 and the bottom plate 102.

[0078] For example, the sealing strip 600 can be in the form of a strip, and the sealing strip 600 can surround a space with an auxiliary gap Z between the bottom plate 102 and the sound barrier 500. Here, the space surrounded by the bottom plate 102 and the sound barrier 500 is the second vibration cavity A2, and the auxiliary gap Z is the third sound outlet gap M3 in communication with the second vibration cavity A2.
