Embodiment Construction

[0021] A flat-panel speaker, including a support frame, is characterized in that: at least one sound unit is arranged along the axial direction of the support frame, and each sound unit consists of a planar vibrating membrane that vibrates and emits sound waves and a frame installed along the periphery of the planar vibrating film and responds to the sound. Vibration of the signal action The driving device of the planar vibrating membrane is composed of at least one pair of non-contact spaces on the side of the ditch part opened on the support frame, and the non-contact space is the ditch opened on the support frame Along a cut corner on the outer side of the bottom surface of the part, the frame installed along the periphery of the planar vibrating membrane is bonded to the grooved part provided on the supporting frame. It is characterized in that: the non-contact spaces on both sides of the ditch part opened on the support frame are symmetrically distributed according to the ...

Abstract

The present invention relates to a tablet loudspeaker, comprising: a support framework. At least one sound producing unit is provided axially along the support framework, and each sound producing unit is formed of a planar vibrating membrane for emitting sound waves by vibration, a frame mounted along the periphery of the planar vibrating membrane, and a drive device for vibrating the planar vibrating membrane in response to a sound signal and an action; a non-contact space is provided on each of the two sides of a trench portion disposed on the support framework, the non-contact space is a chamfer provided on the bottom of the trench portion along the outer side and disposed on the support framework, and the frame mounted along the periphery of the planar vibrating membrane is adhered onto the trench portion disposed on the support framework. The present invention has desirable output frequency characteristics, can also be thinned at high input power, and transmits sound with forward directionality.

Description

technical field [0001] The invention relates to a flat horn. Background technique [0002] In recent years, in order to meet the demand for ultra-thinning of television receivers equipped with speakers, etc., there has been a demand for ultra-thinning of speakers. For such ultra-thin requirements. It is difficult to fully cope with a conical horn that is approximately hemispherical and a conical horn that vibrates a vibrating plate and outputs sound from an opening. The reason for this is that for a conical horn, in order to make the shape ultra-thin, if the cone is thinned, the inner diameter of the cone will also become smaller, and the sensitivity, especially the sensitivity in the low range, will decrease. The conical horn emits sound from the inner surface of the approximately hemispherical cone to the opening. Therefore, the straightness of the sound output by the conical horn is very weak (weak directivity). [0003] Japanese Patent Application Laid-Open No. 2010-...
