An electronic wind instrument includes: a breath sensor; an operating element that receives an instruct related to a pitch; a casing to which the breath sensor and the operating element are provided; a bell having a tubular shape and facing the casing; and a first separate material body that forms a fixing member fixed to the casing and attached to an outer peripheral surface of the bell.

Electronic wind instrument

An electronic percussion instrument includes a head, a frame, and an impact sensor, and a plate serving as a vibration-damping member. The back of the head is divided into a main area (e.g. a main strike area) and an auxiliary area. The plate is ring-shaped sheet, made of a harder material (e.g. a metal) than the head, with an elongated hole and attached to the head to encompass or sandwich the main strike area of the head, thus demonstrating a vibration-damping effect. When the main strike area of the head is being struck with a beater, a vibration is caused to occur in the head and detected by the impact sensor to produce an electric signal which is used to generate an electronic musical sound while the vibration-damping member suppresses vibration being transmitted through the head due to an impact of the beater on the head.

Electronic percussion instrument

An electronic percussion instrument includes a stand, a pad member with a head, and an impact sensor, a cover member, and a support member (e.g. a stay). The support member has an L-shape including a stand-attaching portion and a pad-attaching portion which are perpendicularly unified together at an inflection point. The stand-attaching portion is attached to the stand while the pad-attaching portion is attached to the pad member. The cover member is attached to the support member such that the cover member will not brought into contact with the pad member via a clearance which is maintained irrespective of an impact applied to the head with a beater. The pad-attaching portion is backwardly deflected about the inflection point relative to the stand-attaching portion due to an impact on the head. Thus, it is possible to reduce sound-box reverberations and to secure noiselessness.

An electronic percussion instrument includes a head, a frame, and an impact sensor, and an air ventilation mechanism which includes a pair of cutouts which are distanced from each other and formed in the periphery of the head. The head is attached to the frame such that the periphery of the frame is externally enclosed with the periphery of the head precluding a pair of cutouts. Additionally, a pair of connecting parts with reduced thickness is linearly elongated across the back of the head in parallel. When the head is struck with a beater, a vibration is caused to occur in the head and detected by the impact sensor to produce an electric signal which is used to generate an electronic musical sound, wherein the air ventilation mechanism releases air from the back of the head so as to reliably secure noiselessness while reducing noise.

An electronic percussion instrument includes a head, a frame, and an impact sensor. The back of the head is divided into a main area (e.g. a main strike area) and an auxiliary area. At least one connecting part is arranged above or below the main area in the back of the head and reduced in thickness compared to the auxiliary area, thus reducing vibration from being transmitted through the head. The impact sensor is attached to the back of the main strike area of the head via a cushion member. When the main strike area of the head is being struck with a beater, a vibration is caused to occur in the head and detected by the impact sensor to produce an electric signal which is used to generate an electronic musical sound while suppressing mechanical noise due to an impact between the beater and the head.

An electronic percussion instrument includes a stand, a support member (e.g. a stay), a pad member with a head, and an impact sensor. The support member has an L-shape including a stand-attaching portion and a pad-attaching portion. The stand-attaching portion is fixed to the stand while the pad-attaching portion is extended vertically from the front end of the stand-attaching portion at an inflection point. Owing to the elasticity of the support member, the pad-attaching portion is deflected about the inflection point in the rearward direction in comparison with the stand-attaching portion due to a striking force applied to the head being struck with a beater. Upon detecting an impact applied to the head, the impact sensor generates an electric signal so as to generate a musical sound. Thus, it is possible to suppress floor reverberation by absorbing an impact between the head and the beater via the support member.

An exterior structure for a keyboard instrument, which is capable of dramatically increasing the variation of producible types of keyboard instruments while suppressing the cost of molds. A lower case includes a front-side lower case LCf and a rear-side lower case LCr disposed rearward of the front-side lower case LCf in a side-by-side fashion. An upper case UC is disposed above the lower case. The front-side lower case LCf is fastened to the upper case UC, and the rear-side lower case LCr is fastened to the upper case UC, whereby the lower case is secured to the upper case UC.
