Description

Gluing structure of dustproof cap and cone in loudspeaker

Technical Field

The utility model relates to the field of speakers, in particular to a gluing structure of a dustproof cap and a cone in a speaker.

Background

A speaker is a device that converts an electric signal into a sound signal and plays the sound signal. The main components of the loudspeaker are a sound basin, a voice coil, a damper, a magnet and a dust cap, when the voice coil of the loudspeaker is electrified with audio current, the voice coil generates an alternating magnetic field under the action of the current, and the magnet also generates a constant magnetic field with unchanged size and direction. The magnitude and direction of the magnetic field generated by the voice coil are continuously changed along with the change of the audio current, so that the interaction of the two magnetic fields enables the voice coil to move perpendicular to the current direction in the voice coil.

The dustproof cap arranged on the loudspeaker is used for preventing dust and protecting the loudspeaker box. Under the operating condition of the loudspeaker, high-strength up-and-down movement can cause air to be compressed and not discharged from the bottom, so that the dust cap can be directly impacted, and the existing dust cap can be fixedly connected with the cone through a gluing structure.

Referring to fig. 1, the bonding structure of the existing dust cap and the cone is: the top of cone sets up the limit structure who is used for placing the dust cap, and limit structure is passed through at the both ends of dust cap and is connected with the cone, and the contact surface of dust cap both ends bottom and limit structure is established to the viscose face, and is fixed through glue connection.

The defect of the gluing structure of the prior dustproof cap and the cone is that: because the glue is smeared on the platform of the limiting structure, the quantity of the glue is difficult to control accurately, if the quantity of the glue is too small, the bonding is unstable, and poor quality of the loudspeaker is caused; if the glue amount is too large, the glue overflows the cone, and the appearance and the product quality are affected.

Accordingly, there is a need for an improvement in such a structure to overcome the above-described drawbacks.
