Description

Technical Field

[0001] This utility model relates to the field of loudspeaker equipment, and in particular to a nano-diaphragm paper cone vehicle loudspeaker equipment. Background Technology

[0002] A paper cone loudspeaker is a type of electrodynamic loudspeaker, also known as a direct-radiating electrodynamic loudspeaker. It uses a paper cone as its diaphragm to radiate sound waves. A magnetic system forms a ring-shaped gap. A voice coil carrying an audio signal current is embedded in this gap. The voice coil vibrates according to the audio signal, causing the connected paper cone to vibrate and radiate sound waves. Paper cone loudspeakers are the most widely produced type of loudspeaker in the world. Paper cones come in both round and oval shapes.

[0003] This application improves upon existing technology. In existing nano-diaphragm paper car loudspeakers, the outer periphery of the paper cone's suspension edge is coated with adhesive, and the body is then glued and fixed to the suspension edge. The assembly between the suspension edge and the body is completed by using glue. However, this glue fixing method is not only cumbersome and time-consuming, and inconvenient for assembly and connection, but also causes the paper cone to vibrate with the voice coil. Under the action of vibration, the glued joints may detach, leading to the separation between the suspension edge and the body, reducing the service life and affecting the sound quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nano-diaphragm paper cone vehicle-mounted speaker device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nano-diaphragm paper cone vehicle speaker device includes a magnetic mounting base. A vehicle speaker frame is fixedly connected to the top of the magnetic mounting base. A nano-diaphragm body is housed within the vehicle speaker frame. A voice coil is fixedly connected to the inner wall of the nano-diaphragm body, and a voice coil brake disc is fixedly connected to the outer wall of the voice coil. Multiple equidistant damping elements are installed at the bottom of the voice coil brake disc, and these damping elements abut against the vehicle speaker frame. A pressure ring abuts against the top of the nano-diaphragm body. Symmetrically distributed slots are formed on both sides of the pressure ring. Symmetrically distributed locking blocks are slidably connected to both sides of the vehicle speaker frame. The locking blocks are adapted to the slots. A spring is fixedly connected to one end of each locking block that extends into the vehicle speaker frame, and the other end of the spring is fixedly connected to the vehicle speaker frame.

[0007] By adopting the above technical solution, the combination of the card block and the card slot facilitates the limiting of the pressure ring and the fixation of the nanodiaphragm body.

[0010] As a further improvement of this utility model: the bottom of the voice coil brake disc is fixedly connected with symmetrically distributed positioning posts, and the top of the vehicle speaker frame is provided with symmetrically distributed positioning grooves, which are adapted to the positioning posts.

[0011] By adopting the above technical solution, the positioning column and positioning groove facilitate the installation and positioning of the nanodiaphragm body.

[0016] By adopting the above technical solution, the guide groove facilitates the movement and guidance of the card block.

[0017] As a further improvement of this utility model: the top of the vehicle speaker frame is provided with symmetrically distributed T-shaped sliding grooves, the T-shaped sliding grooves are connected to the guide grooves, and the inner wall of the T-shaped sliding grooves is slidably connected to a slider, and the slider is fixedly connected to a locking block.

[0018] By adopting the above technical solution, the slider facilitates the movement of the card block.

[0019] This utility model has the following beneficial effects:

[0020] In this invention, during installation, the nanodiaphragm body is pushed so that the positioning post at the bottom of the voice coil brake disc enters the positioning groove. The pressure ring is pressed so that the pressure ring abuts against the top of the nanodiaphragm body. At this time, the slot and the block are at the same height. The guide groove resets and drives the block to reset, so that the block enters the slot to limit the pressure ring, thereby fixing the nanodiaphragm body. This facilitates the installation and disassembly of the nanodiaphragm body and makes it easy to replace the nanodiaphragm body. Attached Figure Description
