Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A speaker assembly and an electronic apparatus according to an embodiment of the present invention are described below with reference to fig. 1 to 5.

As shown in fig. 1 to 4, a speaker assembly according to an embodiment of the present invention includes: a speaker 1 and a frame 2. The speaker 1 is provided with a sound outlet hole 121, the frame body 2 encloses an accommodating space 21, the speaker 1 is disposed in the accommodating space 21, and the sound outlet hole 121 of the speaker 1 is disposed on a side (such as the front side of the speaker 1 in fig. 2) adjacent to the inner wall of the frame body 2.

The frame 2 is provided with a sound inlet 2411, a first sound outlet 22, a second sound outlet 23 and a sound outlet channel 24, wherein the sound inlet is located on one side of the frame 2 facing the loudspeaker 1 and is opposite to and communicated with the sound outlet 121. The first sound outlet 22 is located on a side of the frame 2 away from the accommodating space 21 (e.g., a front side of the frame 2 in fig. 2), the second sound outlet 23 is located on a side of the frame 2 in a thickness direction (e.g., an upper side of the frame 2 in fig. 2), and the first sound outlet 22 and the second sound outlet 23 are communicated with the sound inlet 2411 through the sound outlet channel 24.

According to the utility model discloses a speaker assembly, because the lateral wall that goes out sound hole 121 and is close to framework 2, advance sound mouth 2411 and be located framework 2 towards one side of speaker 1 and relative and the intercommunication with going out sound hole 121, first sound mouth 22 and second sound mouth 23 are gone out through going out sound passageway 24 and are advanced sound mouth 2411 intercommunication to the phonation air current that speaker 1 produced can be carried to first sound mouth 22 and second sound mouth 23 through going out sound passageway 24. The utility model discloses a speaker subassembly is through optimizing out 24 structures of sound passageway, can shorten the circulation route of air current, reduces the loss of audio frequency bandwidth, can keep speaker subassembly's loudness, and the quality of stereophonic sound is better, improves user's use and experiences the sense.

It can be understood that, in the related art, a long and thin special-shaped sound outlet channel is provided between the speaker assembly and the frame body, and the speaker assembly guides the sound to the narrow slit of the screen through the special-shaped sound outlet channel. However, the audio bandwidth is lost due to the slender and long special-shaped sound channel, so that the loss of the music playing effect is caused, and the stereo effect is poor.

And because the utility model discloses a speaker subassembly is through setting up sound channel 24 on framework 2 and directly relative with play sound hole 121 to can shorten sound channel 24's length, and make the more smooth and easy of air current send out, and reached the effect that reduces the ante-chamber space, and reduce gas flow velocity, thereby reach the effect that improves effective sound bandwidth, and then can promote the music and put the degree of reduction of effect outward, reach better subjective experience.

Alternatively, as shown in fig. 2 and 3, the sound outlet channel 24 includes a first channel 241 and a second channel 242, a first end of the first channel 241 (e.g., a rear end of the first channel 241 in fig. 3) is a sound inlet 2411, a second end of the first channel 241 (e.g., a front end of the first channel 241 in fig. 3) is communicated with the first sound outlet 22, a second end of the second channel 242 (e.g., a lower end of the second channel 242 in fig. 3) is communicated with a first end of the second channel 242, and a second end of the second channel 242 (e.g., an upper end of the second channel 242 in fig. 3) is a second sound outlet 23. The first channel 241 extends in a direction toward the first sound outlet 22, and the second channel 242 extends in a direction toward the second sound outlet 23.
