Annular sound field loudspeaker

Abstract

The invention relates to an annular sound field loudspeaker, being characterized in that annular magnets are arranged on the upper end face and the lower end face of a shell; and the annular sound field loudspeaker also includes an annular rail, vibrating tubes and a vibrating cavity; a conducting ring is arranged close to each of the inner ring wall and the outer ring wall of the annular rail; aconducting bar made of ferromagnetic materials is arranged in the annular rail in a sliding mode, and the two conducting rings are electrically communicated through the conducting bar; the vibrating tubes are arranged in the shell and are distributed along the radial direction of the shell; permanent magnets are arranged in the vibrating tubes in a sliding manner, and the permanent magnets are kept in airtight contact with the tube walls of the vibrating tubes during reciprocating sliding; the vibration cavity is arranged on the outer ring wall of the shell and comprises a vibrating diaphragmmade of an elastic material; and one end of the each vibrating tube is close to the annular rail, and the other end of the vibrating tube is communicated with the vibrating cavity. The annular sound field loudspeaker is novel in structure and unique in principle, can provide a balanced and full sound field in a wide range, and can effectively improve the auditory experience of the loudspeaker.

Description

technical field [0001] The present invention relates to a loudspeaker device, in particular, a loud field loudspeaker. Background technique [0002] The speaker is one of the important components of audio equipment. The speaker produces sound through the vibration of the paper cone; most of the speakers currently use a horn-shaped paper cone, which is why the speaker is also called a horn; the sound field produced by this speaker has Directionality, a relatively full sound field is only formed in the cone-shaped area in front of the paper cone, and unclear sound will be heard on the side or back of the speaker, especially when enjoying music, movie special effects, etc., the horn-shaped speaker It can only provide a good listening experience in a narrow range, while the experience in other positions is poor. Contents of the invention [0003] In view of the above problems, the present invention provides a ring-shaped sound field loudspeaker, which has a novel structure an...
