Description

Horn with LED lamp

Technical Field

The invention relates to the technical field of horns, in particular to a horn with an LED lamp.

Background

The loudspeaker is widely used as entertainment equipment in the life of people, and people commonly use loudspeakers with various specifications, shapes and different sizes to listen to music, such as home audio equipment, vehicle-mounted loudspeakers and portable small loudspeakers. In order to make the appearance of the loudspeaker more attractive, and increase broadcasting effect, people often install some luminous accessories on the loudspeaker, so that the loudspeaker can emit lights with different colors and different brightness according to melodies, volume and the like during broadcasting. These lighting fixtures are commonly referred to as atmosphere or color lamps. However, the service life of the atmosphere lamp is generally short, the atmosphere lamp is easy to damage, and the service life of the horn is long, so that the horn can sound frequently, but the condition that the atmosphere lamp is damaged occurs. At this time, it is very difficult to replace the damaged atmosphere lamp, even the original structure of the horn is damaged, and the user can only select the horn which is damaged when the atmosphere lamp is used.

Disclosure of Invention

According to the invention, the LED lamp and the driving circuit thereof are arranged in the shell, so that the atmosphere lamp LED lamp is modularized, the LED lamp module is arranged on the mounting seat in a pluggable manner, and the mounting seat is fixed with the loudspeaker through the mounting frame, so that the loudspeaker with the atmosphere lamp capable of being conveniently maintained and replaced is formed.

In order to achieve the above purpose, the invention adopts the following technical scheme: the utility model provides a take loudspeaker of LED lamp, loudspeaker is including the basin frame, be equipped with the LED lamp module on the basin frame, the LED lamp module is including the casing, install the LED lamp in the casing, the LED lamp drive circuit board of LED lamp is connected to the electricity, install the mounting bracket on the basin frame, the inside sunken mount pad that forms in middle part of mounting bracket, in the mount pad was gone into to the casing card, connect through a plurality of screw detachable between casing and the mount pad, the contact shell fragment is installed to the bottom of casing, install the lower contact shell fragment corresponding with last contact shell fragment in the mount pad, the last contact shell fragment is in contact with corresponding lower contact shell fragment electricity after the casing is packed into the mount pad, go up the contact shell fragment and connect LED lamp drive circuit board, lower contact shell fragment passes through the wire and connects loudspeaker.

The shell is provided with a plurality of positioning pins, the mounting seat is provided with positioning holes corresponding to the positioning pins, and the positioning pins are inserted into the positioning holes after the shell is clamped into the mounting seat.

The upper contact spring plate and the lower contact spring plate are identical in structure and symmetrically arranged, the upper contact spring plate and the lower contact spring plate both comprise fixing parts, the lower ends of the fixing parts are bent upwards to form contact parts, two sides of each contact part are respectively connected with supporting parts, clamping grooves for fixing the fixing parts in an inserted mode are respectively formed in the shell and the mounting seat, protrusions are arranged on two sides of each clamping groove, and the fixing parts are abutted to the supporting parts after being inserted into the clamping grooves.

The working principle of the invention is as follows: when the LED lamp is broken or the LED lamp driving circuit board is broken, the damaged part can be easily replaced or maintained by unscrewing the screw.

The beneficial effects of the invention are as follows: according to the loudspeaker with the LED lamp, the LED lamp is modularized, and the LED lamp module can be quickly replaced without complex steps such as disconnecting and connecting in the traditional loudspeaker. The LED lamp module can be continuously installed on the loudspeaker for use after maintenance and upgrading, and a user can even match LED lamp modules of different types and different functions on one loudspeaker for use.
