Description

Technical Field

[0001] The utility model relates to the field of loudspeakers, in particular to a sound cone for a loudspeaker which is easy to replace. Background Art

[0002] A speaker is a transducer device that converts electrical signals into sound signals. It primarily consists of a permanent magnet, a coil, and a paper cone. When an audio current passes through the coil, it generates a magnetic field. This magnetic field interacts with the magnetic field of the permanent magnet, causing the coil to vibrate within the field. The coil is connected to the paper cone, which vibrates with the coil's vibrations, pushing the surrounding air to generate sound waves, ultimately converting the electrical signal into audible sound.

[0003] The cone of a traditional speaker is usually fixed to the speaker frame by gluing and mechanical nesting. When the paper membrane of the cone is broken or the connection between the voice coil and the cone is damaged, a lot of time is wasted to replace it. When the cone is disassembled, the cone itself and the speaker frame are often damaged, which greatly increases the maintenance cost. For this reason, we have proposed a speaker cone that is easy to replace. Utility Model Content

[0016] Compared with the prior art, the present invention provides a speaker cone that is easy to replace, which has the following beneficial effects:

[0017] 1. The speaker uses a cone that is easy to replace. The positioning column is movably connected to the top plate and is threaded with the rotating block to provide a stable fixing base for the quick-release device. During use, the positioning column can ensure the accurate position of the top plate and the fixed plate, and ensure the stability of the sound structure. The combined design of the rectangular block, the rotating column and the linkage block increases the stability and reliability of the quick-release device. In the fixed state, the rectangular block and the linkage block can withstand a certain amount of pressure to ensure that the positioning column is firmly connected to the top plate and the fixed plate. When the cone needs to be replaced, only the rotating block needs to be rotated to easily move the positioning column up and down, and the separation and installation of the top plate and the fixed plate can be quickly completed, so that the cone can be replaced in a short time.

[0018] 2. The speaker uses an easily replaceable cone. Four sets of quick-release devices are arranged in a matrix around the cone, providing uniform fixing force. During the disassembly and installation process, it can ensure that the top plate and the fixing plate are evenly stressed and will not tilt or become unstable, thereby protecting the cone and other components from damage. At the same time, this design also increases the overall stability and reliability of the audio device, greatly reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS
