Description

Technical Field

[0001] This utility model belongs to the field of electric piano technology, specifically relating to a freely configurable portable electric piano. Background Technology

[0002] With the rapid development of digital pianos, in addition to matching mechanical pianos in terms of sound quality, digital pianos have also been greatly improved in terms of weight and portability. To facilitate portability, various folding structures have emerged for digital pianos, significantly reducing their volume and transportation costs. However, current folding pianos use hinge mechanisms for connection. For example, in a publicly disclosed folding digital piano (publication number CN213659984U), the left and right piano bodies connected by the hinge mechanism cannot be completely separated. On the one hand, the left and right piano bodies remain connected; on the other hand, the hinge mechanism is prone to breakage during long-term use. If two people are playing a piece together, the left and right piano bodies cannot be operated independently, and it is impossible for two people to play a piece face-to-face.

[0003] This case arose in response to the aforementioned technical deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a portable electric piano that can be separated into two independent units that can be assembled face-to-face.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable electric piano, which is composed of a piano body, characterized in that the piano body is divided into two parts to form a left and right piano body structure, and the left and right piano bodies are directly connected to each other by magnetic female and magnetic male connectors.

[0006] The magnetic female head is fixed to one end face of the left or right piano body, and is electrically connected to the PCB board built into the piano body.

[0007] The magnetic male connector is fixed to one end face of the right or left piano body, and is electrically connected to the PCB board built into the piano body.

[0008] An additional data cable can be connected between the magnetic female connector and the magnetic male connector.

[0009] The magnetic male connector has a magnetic contact surface at its peripheral edge and two rows of raised metal contacts at its center.

[0010] The magnetic chuck has a magnetic contact surface at its periphery and two rows of concave metal contacts at its center.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model electrically connects the two halves of the piano body by interlocking the magnetic male and female contacts arranged in double rows. The double-row metal contacts have the advantages of tighter interlocking and stronger electrical contact performance. In addition, an infinitely long data cable can be connected between the magnetic male and female contacts, so the left and right sides of the piano body can be freely placed, making it more convenient for two people to play the same piece face to face at the same time, with a high degree of freedom of expression.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] This invention addresses the shortcomings of existing folding piano hinge mechanisms, which cannot completely detach the left and right piano bodies and have an unreliable connection.

[0019] Please see Figures 1 to 3 As shown in Embodiment 1, a portable electric piano is composed of a piano body, which is divided into two parts to form left and right piano body structures. The left and right piano bodies (1, 2) are directly connected to each other by magnetic female connector 4 and magnetic male connector 5. Magnetic female connector 4 and magnetic male connector 5 form a magnetic electrical connector that attracts each other and connects the circuit.

[0020] The magnetic female head 4 is fixed to one end face of the left piano body 1 or the right piano body 2, and the metal contact inside the magnetic female head 4 is electrically connected to the PCB board built into the piano body.

[0021] The magnetic male head 5 is fixed on one end surface of the right piano body 2 or the left piano body 1, and the metal contact on the magnetic male head 5 is electrically connected with the PCB in the piano body.

[0022] The magnetic male head 5 is fixed on one end surface of the right piano body 2 or the left piano body 1, and the metal contact on the magnetic male head 5 is electrically connected with the PCB in the piano body.

[0023] The magnetic male head 5 is fixed on one end surface of the right piano body 2 or the left piano body 1, and the metal contact on the magnetic male head 5 is electrically connected with the PCB in the piano body.

[0024] As shown in Figure 4 As shown in

[0025] The utility model mainly solves the problem that: utilize the magnetic electric connector of double row metal contact to connect the left and right piano body (1, 2) directly, or utilize the data cable (6) of infinite length to connect the left and right piano body (1, 2) indirectly, and the piano body playing mode is free to play.
