Example Embodiment

[0018] Refer to the attached Figure 1 to Figure 6 The embodiment of a tripod type speaker of the present invention will be further described in detail.

[0019] from figure 1 and figure 2 It can be known that a tripod-type speaker includes tripod shell 1, tripod cover 2 and sound-generating assembly 3. The tripod shell 1 and tripod cover 2 are made of aluminum casting, wherein die-casting aluminum has rigidity The characteristics of strong, good heat dissipation and long life are convenient for heat dissipation, and at the same time, it can effectively avoid the deformation of the tripod speaker, and effectively ensure the normal sound.

[0020] from image 3 It can be seen that two symmetrically arranged three-stage amplification channels 11 are provided on one end surface of the tripod housing 1 facing the tripod cover 2, and the other end surface is provided with a sounding chamber 12 for placing the sounding component 3, so that the The two three-stage amplification ...

Abstract

The invention discloses a foot stand type loudspeaker. The loudspeaker comprises a foot stand shell, a foot stand cover and a sound production assembly; two three-stage amplification sound channels which are symmetrically arranged are arranged on one end surface, facing to the foot stand cover, of the foot stand shell, and a sound production cavity used for placing the sound production assembly isarranged on the other end surface of the foot stand shell, so that the foot stand type loudspeaker can produce a sound in front and back directions, and balanced caution can be realized on the frontand back sides of a police car after the foot stand type loudspeaker is mounted on the police car; the overall height of the foot stand type loudspeaker is effectively reduced, so that the foot standtype loudspeaker is more compact; each three-stage amplification sound channel communicates with the sound production cavity through two sound outlets; the two sound outlets are combined, so that theproduced sound is more powerful; the other end of each sound channel is bent and outwards extends to the corresponding side wall of the foot stand shell; and a large sound production drum is arranged,so that the sound can be subjected to three-stage amplification, and the produced sound is also guaranteed to be more powerful.

Description

technical field [0001] The invention relates to a tripod type loudspeaker. Background technique [0002] At present, single speakers and tripods are more and more widely used, such as police cars, ambulances and other emergency vehicles, but usually these speakers and tripods are independent, with small integration, large duty cycle, and long The information integration of the row of warning lights is small. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a tripod type loudspeaker. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A tripod-type loudspeaker, including a tripod shell, a tripod cover and a sound-generating assembly, two symmetrically arranged three-stage amplification channels are arranged on one end face of the tripod shell facing the tripod cover, and two symmetrically arranged three-stage amplification channels...
