Description

Technical Field

[0001] The utility model relates to the technical field of speakers, in particular to a novel high - frequency sound cavity. Background Art

[0002] A speaker is a device in an audio system used to convert an audio signal into sound. It vibrates the air through an internal speaker (also called a horn), thereby emitting sound audible to the human ear. It is an essential part of an audio system and is widely used in various occasions such as home entertainment, public broadcasting, conference rooms, stage performances, etc.

[0003] In the design of speakers, in order to optimize the sound reproduction effect, the high - frequency and mid - frequency units are placed at specific positions and equipped with corresponding cavity structures. Due to the need for a higher frequency response and a smaller physical size, the high - frequency unit is usually placed at the upper or front part of the speaker and is equipped with an independent chamber and a guiding hole to ensure the clarity and penetration of the high - frequency sound. The mid - frequency unit is generally located between the high - frequency and low - frequency units, and its cavity size is moderate to meet the response requirements of mid - frequency sounds. The mid - frequency cavity is generally also a separate chamber. However, for the lightweight design of the speaker, the internal space is very limited, and separate high - frequency and mid - frequency chambers are difficult to adapt to the internal space requirements of the speaker. Therefore, the utility model proposes a novel high - frequency sound cavity to solve the problems existing in the prior art. Summary of the Utility Model
