Specifically, please refer to FIG. 2 , a part of the sound outlet 11 is blocked. The airflow velocity of the sound outlet 11 of the speaker element 10 is often relatively large, which blocks part of the sound outlet 11, reduces the airflow velocity of the sound outlet 11 of the housing 1, and reduces sound distortion and noise. Therefore, a speaker device 10 and a mobile terminal 100 with better sound quality are provided.

It can be understood that, referring to FIG. 3 , the speaker element 10 further includes an airflow buffer 3 , and the airflow buffer 3 is disposed at the sound outlet 11 of the casing 1 to block the outlet of the casing 1 . part of the sound port 11.

For further improvement, please refer to FIG. 3 and FIG. 4 , the airflow buffer 3 is disposed in the middle area of the sound outlet 11 along the extending direction of the long side 1 a of the sound outlet 11 . Specifically, the inventor learned from a large amount of experimental data that the airflow velocity in the middle area of the sound outlet 11 is the highest, and arranging the airflow buffer 3 in the middle area can minimize audio distortion and noise generation. Of course, in other embodiments, the airflow buffers 3 may also be disposed on both sides of the middle area of the sound outlet 11 .

In one embodiment, please refer to FIG. 3 , the airflow buffer 3 is integrally formed with the housing 1 . That is, when the casing 1 is processed and formed, the airflow buffer member 3 is directly formed in the middle area of the sound outlet 11 of the casing 1 , which facilitates the installation of the speaker member 10 .

In another embodiment, please refer to FIG. 4 , the airflow buffer 3 is detachably connected to the sound outlet 11 of the housing 1 . Specifically, the airflow buffer 3 is formed on other components. When the other components are installed with the casing 1 , the airflow buffer 3 formed on the other components is aligned with the sound outlet 11 so as to be detachably connected to the outlet of the casing 1 . In the sound port 11 , the airflow buffer 3 can extend into the sound outlet 11 , or the airflow buffer 3 can resist the edge of the sound outlet 11 , so that part of the sound outlet 11 is blocked. It can be understood that the speaker component 10 further includes a casing 4, that is, the other components are the casing 4 assembled with the casing 1. The casing 4 may be a front casing or a middle frame of the mobile terminal 100, and the casing 4 is facing the The airflow buffer 3 is set at the position of the sound outlet 11 , so that when the outer casing 4 is attached to the casing 1 , the airflow buffer 3 is inserted into the sound outlet 11 of the casing 1 . , to block part of the sound outlet 11, reduce the airflow velocity of the sound outlet 11 of the housing 1, reduce the problems of sound distortion and mixed noise, thereby providing a speaker device with better sound quality 10.

It can be understood that, referring to FIG. 3 and FIG. 4 , the airflow buffer 3 may include at least one strip-shaped rib 31 , and the strip-shaped rib 31 spans the two long sides 1 a . Specifically, the strip-shaped rib 31 is one, which covers the middle area of the sound outlet 11 . Referring to FIG. 3 , if the airflow buffer 3 is formed directly on the casing 1 , when manufacturing the casing 1 , a strip-shaped rib 31 can be formed directly in the middle of the sound outlet 11 . Referring to FIG. 4 , if the airflow buffer 3 is inserted into the sound outlet 11 , the strip-shaped rib 31 is protruded on the position where the casing 4 is aligned with the middle area of the sound outlet 11 , so that the casing 4 can be easily installed on the sound outlet 11 . When the casing 1 is installed, the strip-shaped rib 31 on the casing 4 can be aligned with the middle area of the sound outlet 11, so that the strip-shaped rib 31 can span the two long sides 1a of the sound outlet 11 to realize the sound outlet. Part of the area 11 is blocked, which reduces the airflow velocity of the sound outlet 11 of the housing 1, reduces the problems of sound distortion and mixed noise, thereby providing a speaker device 10 with better sound quality. Of course, in other embodiments, the number of bar-shaped ribs 31 may be two, three, etc. The plurality of bar-shaped ribs 31 are centrally arranged in the middle position of the sound outlet 11 , and two adjacent bar-shaped ribs 31 are spaced apart. Of course, in other embodiments, the bar-shaped rib 31 may also be a triangle as shown in FIG. 5 , a trapezoid as shown in FIG. 6 , or a lightning bolt as shown in FIG. 7 .

Referring to FIG. 8 , a mobile terminal 200 provided by the second embodiment of the present invention is basically the same as the mobile terminal 100 provided by the first embodiment, except that the airflow buffer 3 includes at least one sawtooth The at least one sawtooth part 32 is arranged on the two long sides 1a; or, or the at least one sawtooth is arranged on one of the long sides 1a of the sound outlet 11 .

Specifically, please refer to FIG. 8 , the edges of the two long sides 1a of the sound outlet 11 form a sawtooth portion 32 respectively. Since the lengths L of the sawtooth portions 32 along the width D direction of the sound outlet 11 are inconsistent, it can further The airflow is relieved and the sound quality of the audio is improved.

It can be understood that one of the serrated portions 32 is arranged on one long side 1a of the sound outlet 11 , and the other serrated portion 32 is arranged on the other long side 1a of the sound outlet 11 . The serrated portions 32 are facing each other, and a space between the two serrated portions 32 is set between the two serrated portions 32 . That is, the middle position of the sound outlet 11 between the two sawtooth portions 32 can still allow airflow to pass through, but the airflow speed at this time is small and will not affect the sound quality of the speaker device 10 . Of course, in other embodiments, no gap may be provided between the two serrated portions 32 , that is, the two serrated portions 32 are connected together to form a serrated portion 32 , which is similar to the bar-shaped rib 31 in the first embodiment.

When the mobile terminal 100 provided in this embodiment of the present invention is applied, the audio of the mobile terminal 100 is output from the sound outlet 11 of the speaker element 10. Since part of the sound outlet 11 of the casing 1 is blocked, the output of the casing 1 is reduced. The airflow speed of the sound port 11 reduces the problems of sound distortion and mixed noise, thereby providing a speaker and mobile terminal 100 with better sound quality.
