摘要： A full-frequency band high quality planar resonance speaker with a bar and sound tunnels comprises a diaphragm; the diaphragm is planar, of which the outer edge is connected to the outer frame of the speaker through an elastic connector; a sound source is arranged in the middle of the diaphragm; the first groove and the second groove are arranged on the surface of at least one side of the diaphragm; the first groove and the second groove are crossed and connected with each other on the surface of the diaphragm, and the surface of the diaphragm is equally divided into four resonance regions; the diaphragm is also provided with a bar assembly at the center of the same side surface with the two grooves; the bar assembly comprises a plurality of strip-shaped bar members, which are arranged on both sides of the first groove and the second groove in pairs; the first groove and the second groove respectively form a sound tunnel on the surface of the diaphragm. This invention changes the diaphragm from the previous free vibration mode to the current standard vibration mode, and solves the problem that the timbre of treble register of the previous planar resonance speaker is not bright and the timbre of bass register is not sonorous and mellow enough from the perspective of vibration, resonance and phonation. The practice proves that the improved scheme has outstanding substantive characteristics and remarkable technical progress, and has obtained obvious technical results.

摘要： [0058] A circuit substrate includes an outer plated through hole structure and an inner plated through hole structure located within the outer plated through hole structure. In one example, the circuit substrate includes a core and an outer plated through hole structure having a first metal layer configured over the core to form an outer plated through hole. The circuit substrate also includes an inner plated through hole structure located within the outer plated through hole structure having a second metal layer positioned inside of the outer plated through hole with an insulation layer interposed between the first and second metal layers. Methods for making such a circuit substrate are also described.

摘要： A kind of double-bars violin family without sound post, comprising a resonance box, which is composed of a front plate , a back plate and sidewalls, characterized in that:
Two upper bars are fixed on the inner wall of the front plate in parallel; Two lower bars are fixed on the inner wall of the back plate in parallel; An upper cross groove is arranged on the inner wall of the front plate, and the upper cross groove forms an upper cross sound tunnel on the inner wall of the front plate; A lower cross groove is arranged on the inner wall of the back plate, and the lower cross groove forms a lower cross sound tunnel on the inner wall of the back plate. This scheme breaks the shackles of the traditional bass bar and sound post design in resonance box of violin family, cancels the sound post in resonance box of violin family, and boldly proposes a new improved design scheme, which solves the problem that the treble register of the violin family is not bright, while the bass register is not sonorous and mellow enough, so that the resonance box can give good consideration to the treble, alto, and bass registers with good timbre.
