Description

Speaker unit including a vent cover {SPEAKER UNIT WITH VENT COVER}

The present invention relates to a speaker unit including a vent cover, and more specifically, to a speaker unit including a vent and a vent cover covering the vent.

A speaker converts electrical signals into sound through vibration.

In a speaker, the permanent magnet, plate, and yoke make up the magnetic circuit. A gap is formed between the yoke and the permanent magnet, and a voice coil is disposed within the gap. The magnetic flux generated from the permanent magnet is trapped within the yoke and permanent magnet gap by the plate, and the voice coil vibrates according to the change in polarity of the current under the influence of the magnetic flux.

When current flows through a voice coil placed in a magnetic field, the voice coil receives force and vibrates according to Fleming's left-hand rule. The vibrations of the voice coil are transmitted to the vibrating body, and a wave is generated according to the vibration of the vibrating body. It corresponds to a sound whose wave is a sound wave.

The speaker may be built into the case or housing of a wearable device such as headphones or earphones. Speakers included in headphones or earphones are also called speaker units. The speaker unit includes a frame and a transducer called a driver.

The speaker unit may be configured to include a mesh member covering a vent formed therein. However, there are many cases where moisture causes the mesh member to separate from the joint.

As a technology related to the present invention, an earphone with a sound tuning mechanism disclosed in the Korean Patent Publication performs sound tuning using a primary output opening and a secondary output opening, but the primary output opening and the secondary output opening are Since the vent in the present invention is formed in the housing, the purpose, structure, and effect of the two inventions are distinct from each other.
