Description

Novel loudspeaker sounding device

Technical Field

The utility model relates to the technical field of loudspeaker sounding devices, in particular to a novel loudspeaker sounding device.

Background

A horn is a device that converts electrical energy into sound. Most of the horns in the market at present are designed by paper cone, and the sound production principle is that current passes through a coil to form a magnetic field to drive the paper cone to vibrate so as to force air to vibrate and produce sound. When the electric sounding device works, the coil inputs an audio current signal through the wiring terminal, and an alternating magnetic field changing along with the audio current is generated when the coil passes through the audio current, and the alternating magnetic field interacts with a fixed magnetic field generated by the permanent magnet, so that the coil moves under the action of the magnetic field, thereby driving the cone to vibrate to make a sound, generally, the larger the audio current signal passing through the coil is, the stronger the generated alternating magnetic field is, the larger the vibration amplitude of the cone is, but the larger the audio current signal passing through the coil is, otherwise, the distortion degree of the sound emitted by the loudspeaker is increased, and the voice coil is damaged.

Therefore, a novel horn sounding device is provided for the problems.

Disclosure of Invention

The utility model aims to provide a novel loudspeaker sounding device, which comprises an outer shell, wherein a magnet is arranged in the outer shell, one side, far away from the outer shell, of the magnet is connected with a support frame, a coil is arranged in the support frame, a sound transmission film is further arranged in the support frame and is connected with the coil, a sound amplifying wall is arranged at one end, far away from the magnet, of the support frame, and a plurality of screw holes are formed in the sound amplifying wall.

Further, the sound amplifying wall comprises a sound amplifying wall upper wall and a sound amplifying wall lower wall, and the sound amplifying wall upper wall and the sound amplifying wall lower wall are in oblique angle design, so that the sound amplifying wall is in an oblique angle horn shape.

Compared with the prior art, the utility model has the following beneficial effects: the utility model makes the sound amplifying wall in a bevel horn shape, the upper wall of the sound amplifying wall and one side of the lower wall of the sound amplifying wall form a bevel angle which is inclined from top to bottom to left, the sound source of the sound is blocked by the upper wall of the sound amplifying wall and transmitted to the front, and the rear is blocked by the upper wall of the sound amplifying wall, so that the sound is transmitted forwards as much as possible, and the sound source heard by a person standing in front is the largest.

Detailed Description

As shown in fig. 1 and 2, the novel horn sounding device provided by the utility model comprises an outer shell 1, wherein a magnet 2 is arranged in the outer shell 1, one side, far away from the outer shell 1, of the magnet 2 is connected with a support frame 3, a coil 4 is arranged in the support frame 3, a sound transmission film 5 is further arranged in the support frame 3, the sound transmission film 5 is connected with the coil 4, a sound amplifying wall 6 is arranged at one end, far away from the magnet 2, of the support frame 3, and a plurality of screw holes 7 are formed in the sound amplifying wall 6.

Specifically, the inside of support frame 3 that sound transmission membrane 5 kept away from coil 4 one side is provided with the dust screen.

Specifically, the amplifying wall 6 includes an upper amplifying wall 61 and a lower amplifying wall 62, and the upper amplifying wall 61 and the lower amplifying wall 62 are designed with oblique angles, so that the amplifying wall 6 has an oblique horn shape.

Specifically, the sides of the upper wall 61 and the lower wall 62 of the speaker wall, which are far away from the support frame 3, are inclined at an oblique angle from top to bottom to left.

Working principle: when different electronic energy is transmitted to the coil 4, the coil 4 generates an energy interaction with the magnetic field of the magnet 2, the interaction causes vibration, and because the electronic energy changes at any time, the coil 4 moves forwards or backwards, so that the sound transmission film 5 of the sound generating device moves along, and the action changes the density of the air to transmit sound, when the sound is transmitted to the sound amplifying wall 6, the sound source of the sound is blocked by the upper wall 61 of the sound amplifying wall and transmitted to the front, and then blocked by the upper wall 61 of the sound amplifying wall, and the sound is transmitted forwards as much as possible, so that the sound source of the sound heard by a person standing in front is maximized.
