摘要： The invention relates to a drum having a drum shell which forms an upper and a lower part (1, 2), is divided by a system ring (3) and is covered on each of the two open cover sides by a respective drumhead (4) which is tensioned down on the drum by a respective tension hoop (5) which is fastened to the drum by way of tuning screws (6), wherein the tension hoops (5) are tensioned against the common system ring (3) by way of their respective tuning screws (6) with interposition of the upper and lower parts (1, 2) respectively. In order to create advantageous construction conditions, it is proposed that the drum shell consists at least in sections of stone material and that the upper and lower parts (1, 2) of the two-part drum shell are bonded to the system ring (3) via stone silicone as an adhesive.

摘要： Accessories to improve the tonal qualities of a guitar or other stringed instruments include a bridge sound plate, a bridge support, a stress tube, and one or more bridge pin bolts. A bridge pin bolt may include a head, a shank, a thread, and a nut, the head of the bridge pin bolt having a void therethrough extending from a front of the head to a back of the head to receive a guitar string therethrough, the void extending upwardly from the front of the head to the back of the head. One or more of the accessories may be formed of brass or another material with good tonal properties. A sound plate may be adjustable or tunable. The accessories may be used independently, or may be used together as a system of accessories.

摘要： A method for assisting a user in tuning a drum comprising the steps of: considering a strike on the drum whereby the strike is detected in a sensor signal in at least one of following domains: a time domain, a frequency domain, a complex domain; recording a first sound fragment of the strike; converting the first sound fragment from the time domain to the frequency domain; analyzing the first sound fragment in order to detect a fundamental tone with fundamental tone frequency of the drum; calculating an overtone frequency or overtone frequency range of a first overtone of the drum by means of a predetermined algorithm related to the fundamental tone frequency; setting a filter with a pass frequency band covering the calculated overtone frequency or overtone frequency range; and indicating, via a user interface, at each further strike when the frequency of the first overtone detected in the pass frequency band is higher or lower than a target overtone frequency.

摘要： The present disclosure relates generally to a drum apparatus with advanced acoustic response and methods of manufacturing the drum apparatus. The drum apparatus includes an integral drum body having a side wall defining a resonant chamber. The integral drum body is formed by an additive manufacturing process or with a volume printing material that shapes the side wall to define an acoustic response of the drum apparatus. The side wall is shaped to define a top perimeter region and a bottom region of the integral drum body. The top perimeter region defines a top opening to the resonant chamber and the bottom region defines a bottom of the resonant chamber, opposite the top perimeter region. The side wall has a thickness or mass distribution controlled by the additive manufacturing process or defined by the volume printing material to modulate the acoustic response of the drum apparatus.
