Description

Technical Field

[0001] The present application relates to the technical field of audio equipment, and more specifically, to an earphone and an earphone assembly. Background Art

[0002] Earphones are devices that convert electrical signals into sound signals for the purpose of disseminating sound. Earphones generally include an earphone shell, an earphone handle, a speaker, a battery assembly, and a circuit board assembly. A accommodating cavity is formed inside the earphone shell. The speaker is installed in the accommodating cavity and connected to the battery assembly. The speaker has a sound output surface for dispersing sound outward. When the speaker makes a sound, one side of the speaker output surface forms a front sound cavity, and the side away from the speaker output surface forms a rear sound cavity.

[0003] Since the sound emitted by the speaker will be spread in the containing cavity in the form of sound waves, the sound waves will also propagate in the rear sound cavity during the sound generation process of the earphone. At this time, due to the small volume of the rear sound cavity and the small vibration space of the sound waves, the resonance frequency of the low-frequency sound waves in the earphone is relatively high, resulting in the poor low-frequency performance of the earphone.

[0004] In order to effectively improve the low-frequency performance of headphones, a tuning hole connected to the outside is generally opened on the wall of the rear sound cavity so that the sound waves can be transmitted to the outside through the tuning hole. However, the design of the tuning hole alone cannot effectively increase the vibration space of the sound waves. Therefore, the improvement effect of the low-frequency performance is limited, resulting in a poor user experience. Utility Model Content

The handle portion 13 refers to the part connected to the body portion 12, which is exposed outside the auricle when the earphone is worn. In this embodiment, the body portion 12 and the handle portion 13 are bonded together with glue to form a fixed connection.

[0035] In this embodiment, by setting the connecting plate 4 in the handle portion 13 or the compartment body portion 12, the volume of the first chamber 111 can be effectively expanded, thereby facilitating the installation of the battery assembly 3 and the speaker 2, and effectively reducing the low-frequency resonance frequency in the first chamber 111.

[0036] In another optional embodiment of the present embodiment, the connecting plate 4 is arranged parallel to the length direction A of the handle portion 13 .

[0037] In the present embodiment, the length direction A of the handle portion 13 refers to the length direction of the overall extension of the handle portion 13. The present embodiment arranges the connecting plate 4 parallel to the length direction A of the handle portion 13, thereby facilitating the arrangement of the connecting plate 4 in the handle portion 13 and making the inner walls of the first chamber 111 and the second chamber 112 more regular, thereby reducing the low-frequency resonance frequency and obtaining better low-frequency performance.

[0038] In another optional embodiment of the present embodiment, a mounting groove 113 is provided on a side of the first chamber 111 away from the connecting plate 4; the speaker 2 is fixed in the mounting groove 113 to separate the first chamber 111 into a front chamber 111a and a rear chamber 111b, and the battery assembly 3 is arranged in the rear chamber 111b and connected to a side of the speaker 2 facing the interior of the shell 1.

[0039] In this embodiment, the mounting groove 113 is matched with the edge portion of the sound outlet surface 21 of the speaker 2, and the mounting groove 113 and the speaker 2 are bonded by glue to form a connection and fixation.
