The invention discloses a front-mounted compression driving head and a horn loudspeaker. The front-mounted compression driving head comprises a magnet, a diaphragm structure mounted on the magnet, a phase plug in connection with the diaphragm structure and a throat in connection with the phase plug, wherein the diaphragm structure comprises a diaphragm, a metal ring and a voice coil; the diaphragmand the voice coil are disposed on the same side of the metal ring; and the phase plug is connected with a concave surface of the diaphragm. Since the diaphragm and the voice coil in the diaphragm structure of the present application are both disposed on the same side of the metal ring, the diaphragm structure is carried on the magnet, which enables the bending direction of the curved surface ofthe diaphragm in the diaphragm structure is consistent with the compression direction thereof. Therefore, the acoustic wave emitted by the diaphragm structure can be not distorted during transmissionto some extent, thereby reducing the phase distortion and improving the sound quality.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of compression drivers, in particular to a front-mounted compression driver and a horn speaker. Background technique [0002] The horn speaker is composed of a compression drive head and a horn, and has many advantages such as high electro-acoustic conversion efficiency, small distortion, and good transient response. Since the center column and throat of the front compression driver are located on both sides of the diaphragm, the height of the magnet is not limited, so it can be equipped with a larger magnet, so that the front compression driver has higher sensitivity. [0003] But, because the diaphragm arc surface of the pre-type compression driving head in the prior art does not match the direction of compression (as figure 1 As shown), the transmission path of the sound wave emitted by the diaphragm is distorted during transmission, resulting in phase distortion. [0004] In view ...
