Description

Foot rest type loudspeaker

Technical Field

The invention relates to a foot rest type loudspeaker.

Background

At present, single speaker, foot rest application occasion are more and more extensive, such as police car, ambulance etc. some vehicles of handling emergency, but these speaker, foot rest are even independent generally, and the degree of fusion is little, duty cycle is big, long row warning light's informatization integrated level is little.

Disclosure of Invention

Aiming at the defects existing in the prior art, the invention aims to provide a foot rest type loudspeaker.

In order to achieve the above purpose, the present invention provides the following technical solutions:

The foot stool type loudspeaker comprises a foot stool shell, a foot stool cover and a sounding component, wherein one end face of the foot stool shell, which faces the foot stool cover, is provided with two symmetrically arranged three-stage amplifying sound channels, and the other end face of the foot stool shell is provided with a sounding cavity for placing the sounding component;

One end of each three-stage amplifying sound channel is provided with two sound outlets which are communicated with the sound producing cavity, and the other end of each three-stage amplifying sound channel is bent and extends outwards to the corresponding side wall of the foot rest shell, and is provided with a sound producing cylinder.

The sound generating assembly is further provided with the voice coil and the drum basin sound film, wherein the voice coil comprises an annular frame, the drum basin sound film is reversely buckled at the middle position of the annular frame, and the annular frame is provided with a plurality of uniformly distributed magnetic steel grooves for placing magnetic steel.

The invention further provides that the foot rest shell and the foot rest cover are cast by adopting aluminum materials.

Because two three-level amplifying sound channels arranged on the foot rest shell are independently closed to form a single sound source, the foot rest type loudspeaker can sound in a front-back bidirectional way, and the police car can warn in a balanced way in the front-back direction after being installed;

Wherein each three-level amplifying sound channel is communicated with the sound producing cavity through two sound outlets, the two sound outlets are converged to enable sound production to be more powerful and the other end of the three-level amplifying sound channel is bent and outwards extended to the corresponding side wall of the foot rest shell, and a sound producing cylinder is arranged to enable sound to be amplified in three levels and ensure sound production to be more powerful and powerful.

Detailed Description

An embodiment of a foot rest type speaker according to the present invention will be described in further detail with reference to fig. 1 to 6.

From fig. 1 and fig. 2, a foot rest type loudspeaker, including foot rest casing 1, foot rest lid 2 and sound production subassembly 3, foot rest casing 1 and foot rest lid 2 adopt aluminum product casting shaping, and wherein the die-casting aluminum product has the characteristics that the rigidity is strong, the heat dissipation is good, life-span is high, and the heat dissipation of being convenient for effectively avoids foot rest type loudspeaker atress to warp simultaneously, effectively guarantees normal sound production.

As can be seen from fig. 3, an end face of the foot rest shell 1, facing the foot rest cover 2, is provided with two symmetrically arranged three-stage amplifying sound channels 11, and the other end face is provided with a sound producing cavity 12 for placing the sound producing component 3, so that the two three-stage amplifying sound channels 11 arranged on the foot rest shell 1 are independently closed to form a mono-sound source, the foot rest type loudspeaker can emit sound in a front-back bidirectional manner, and the front and back sides of the police car can be uniformly warned after being installed, wherein the three-stage amplifying sound channels 11 and the sound producing cavity 12 are respectively arranged on the upper end face and the lower end face of the foot rest shell 1, the overall height of the foot rest type loudspeaker is effectively reduced, and the foot rest type loudspeaker is more compact.

As can be seen from fig. 4 and fig. 5, one end of each tertiary amplifying sound channel 11 is provided with two sound outlets 13 which are communicated with the sound producing cavity 12, so that each tertiary amplifying sound channel 11 is communicated with the sound producing cavity 12 through the two sound outlets 13, the two sound outlets 13 are gathered to make sound producing stronger and more powerful, the other end of the sound producing channel is bent and outwards extended to the corresponding side wall of the foot rest shell 1, and the sound producing large tube 14 is arranged, so that the sound is amplified three-stage, and the sound producing stronger and more powerful is ensured.

From fig. 6, it can be seen that the sounding component 3 includes a voice coil 31 and a cone sound film 32, where the voice coil 31 includes an annular frame 311, and the cone sound film 32 is reversely buckled at the middle position of the annular frame 311, so that the installation space of the sound film is effectively saved, the overall structure of the speaker is thinner, and the annular frame 311 is provided with a plurality of uniformly distributed magnetic steel grooves 312 for placing the magnetic steel 4, and the neodymium iron boron material is adopted, so that the magnetic flux is high and the cost is low, and the annular frame 311 is adopted to set up the cylindrical magnetic steel 4 to replace the annular magnetic steel 4, thereby effectively reducing the dosage of the magnetic steel 4 and the cost.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above examples, and all technical solutions belonging to the concept of the present invention belong to the protection scope of the present invention. It should be noted that modifications and adaptations to the present invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
