Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0025] Such as Figure 1~6 As shown, a thin speaker enclosure in the embodiment is mainly composed of an upper shell 11, a thin speaker mounting table 11.1, a lower shell 12, a thin speaker mounting hole 12.1, a thin speaker 1, a tweeter 14, a tweeter mounting slot 14.1, and a tweeter heat sink Slot 15, 16 sound holes.

[0026] Such as figure 1 As shown in ~3, the thin speaker is composed of a folding ring cone 2, a cone body 3, a positioning piece 4, a voice coil 5, a U iron 6, a magnet 7, a magnetic pole core 8, a wiring board 9, and a frame 10. The bottom of the basin 10 is provided with a U iron 6, a magnet 7 is provided at the bottom of the U iron 6, a magnetic pole core 8 is provided directly above the magnet 7, and the outer wall of the magnetic pole core 8 and the magnet 7 is left with the inner wall of the U iron 6 A magnetic gap, the voice coil 5 is arran...

Abstract

The invention relates to a thin type loudspeaker sound box. The thin type loudspeaker sound box comprises a box body for containing at least one thin type loudspeaker, a low-frequency sound-guiding plate is arranged right above sound radiation of the thin type loudspeaker, at least a tweeter unit is arranged in the box body, an upper shell of the box body, close to the tweeter unit, is provided with high-pitch radiating grooves to improve the reliability of the tweeter unit during long-term full-load operation, and the thin type loudspeaker is formed by a frame, a U-yoke, a magnet, a T-yoke, a voice coil, a cone with edges, a positioning support plate, and a wiring board. The cone with the edges and the positioning support plate are specially designed so that the overall structural height is reduced on the precise of not reducing the output sound pressure level of the loudspeaker, and the installation and the application in the thin type sound box can be facilitated. According to the thin type loudspeaker sound box, the low-frequency tone quality can be improved with thinner structure, and the reliability is improved.

Description

Technical field [0001] The invention relates to a thin loudspeaker and a thin sound box containing at least one of the loudspeakers, in particular to a thin loudspeaker and sound box suitable for use in audio and video equipment such as large-size flat-panel televisions, belonging to the field of electroacoustic technology. Background technique [0002] In the prior art, in order to improve the sound quality of thin and large-size TVs such as OLED and ULED, multiple speaker units are generally used to form an inverted speaker to improve low-frequency response characteristics. However, this type of sound system is usually limited by the structure and structure of the speaker unit. The installation location and the thickness of the TV's overall structure cannot further enhance the low-frequency volume and the directivity of the low-frequency output under the premise of thinning. Therefore, seeking a thin speaker with bright mid-to-high frequency, sufficient low-frequency volume and...
