In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Moreover, the present application may repeat reference numerals and/or letters in the various examples, such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize applications of other processes and/or use of other materials.

The frame 20 is provided with an accommodating cavity 23, the electroacoustic conversion part 10 is arranged in the accommodating cavity 23, a sunk groove 24 is formed on one side of the accommodating cavity 23 in a sunken mode on the bottom surface 211 of the frame 20, a first tuning hole 40 penetrating through the frame 20 is formed in the sunk groove 24, the first tuning hole 40 is communicated with the sunk groove 24 and the accommodating cavity 23, and the first tuning piece 30 is arranged in the sunk groove 24 and covers the first tuning hole 40.

It can be understood that in the related art, the speaker of the earphone needs to reserve a certain space from other elements of the earphone to improve the sound quality, however, the height of the speaker in the related art earphone is high, which causes the volume of the earphone to be large when the earphone is stacked, and the user experience is affected. For example, taking a wireless earphone as an example, in the prior art, for a wireless earphone with a relatively small volume, due to space limitation, a speaker cannot be far away from functional elements such as a battery, and in order to avoid poor sound quality caused by the fact that sound adjusting holes are blocked by the functional elements and speaker sound generating airflow is not smooth, a spacing space needs to be reserved between the battery and the speaker to reserve a sound generating channel for the air leakage flow after the speaker generates sound. Therefore, the size of the earphone is increased, and the wearing comfort and the appearance of the earphone are affected.

In the speaker 100 and the earphone 1000 according to the embodiment of the present invention, the bottom surface 211 of the frame 20 is formed with the sink 24, and the first tuning member 30 is disposed in the sink 24 and covers the first tuning hole 40 penetrating the frame 20. Therefore, the stacking height of the loudspeaker 100 can be effectively reduced, the space is saved for stacking the earphone 1000 provided with the loudspeaker 100, the size of the earphone 1000 can be effectively reduced, and the use experience of a user is improved.

Referring to fig. 3, the frame 20 is used for fixing the electroacoustic conversion part 10. The frame 20 includes a bottom plate 21 and a side plate 22 connected to the bottom plate 21, the bottom plate 21 may be provided in a circular shape or other shapes, the side plate 22 is provided around the bottom plate 21 and extends upward to enclose an accommodating chamber 23 with the bottom plate 21, and the electroacoustic conversion part 10 may be placed in the accommodating chamber 23.

Referring to fig. 5, in the embodiment of the present application, the bottom plate 21 includes the bottom surface 211, and the bottom surface 211 may be a surface of the bottom plate 21 away from the accommodating cavity 23. The sink 24 may be formed by the bottom 211 being recessed toward the side of the receiving cavity 23. The sink 24 may be a circular groove or a groove with other shapes, and is not limited herein. The center of the sink groove 24 may be coincident with the center of the bottom surface 211, and the depth of the sink groove 24 may be smaller than the thickness of the bottom plate 21. The bottom plate 21 is provided with a first tuning hole 40, the first tuning hole 40 may also be disposed at the center of the bottom surface 211, and the accommodating cavity 23 and the sink 24 are communicated through the first tuning hole 40, that is, in such an embodiment, both the sink 24 and the first tuning hole 40 may be a stepped hole penetrating through the bottom plate 21. The electroacoustic conversion part 10 vibrates and generates sound in the accommodating chamber 23, and the first tuning hole 40 can adjust the frequency of the sound in the accommodating chamber 23.

The area of the first tuning piece 30 may be set to be not smaller than the area of the first tuning hole 40, and the first tuning hole 40 can be completely covered. In one example, the first tuning piece 30 may be used to adjust the mid audio quality and the low audio quality of the speaker 100. The material and shape of the first tuning member 30 are not limited in the present application, and the first tuning member 30 may be sized to cover the first tuning hole 40. Thus, the first tuning piece 30 is arranged in the sinking groove 24, and the first tuning piece 30 covers the first tuning hole 40 to adjust the audio frequency while the thickness of the loudspeaker 100 is not increased, so that the tone quality of the loudspeaker 100 is improved.

Referring to FIG. 2, in some embodiments, the depth of the counter sink 24 is greater than the thickness of the first tuning piece 30, and the first tuning piece 30 is completely contained within the counter sink 24.

Thus, the first tuning element 30 can be completely accommodated in the sink 24 without protruding from the frame 20, the overall thickness of the loudspeaker 100 is reduced as much as possible, and the first tuning element 30 can be effectively protected from scratches.

Specifically, in such an embodiment, the thickness of the first tuning piece 30 may be between 0.05-0.4mm, and the depth of the counter sink 24 is greater than the thickness of the first tuning piece 30. For example, when the thickness of the first tuning piece 30 is 0.1mm, the depth of the sink 24 may be 0.15mm, 0.2mm, 0.25mm, or the like; when the thickness of the first tuning piece 30 is 0.2mm, the depth of the sinking groove 24 can be 0.25mm, 0.3mm, 0.35mm and the like; when the thickness of the first tuning piece 30 is 0.3mm, the depth of the sinking groove 24 may be 0.35mm, 0.4mm, etc.

It should be noted that the outer periphery of the frame 20 refers to an outer side surface of the frame 20 in the circumferential direction, that is, an outer side surface of the bottom plate 21. Specifically, in such an embodiment, the sinking groove 24 penetrates through the outer periphery of the bottom plate 21 to be connected with the outside, so that the accommodating cavity 23 and the outside can be directly communicated through the sinking groove 24, when the frame 20 of the speaker 100 is stacked with other elements in close proximity, other elements (such as a battery of the headset 1000) can be directly attached to the frame 20 of the speaker 100 only, and need not be spaced from the frame 20, thereby improving the space utilization rate of the headset 1000.
