Abstract: An electric drive module and an electric drive equipment are provided, the electric drive module comprises a housing, a force output assembly, a flexible gear, a rotor, a stator, a wave generator, and a cooling pipe, the stator is configured to drive the rotor to rotate relative to the housing, when the rotor rotates, the wave generator drives the flexible gear to deform to drive the rigid gear to rotate, at least part of the cooling pipe is received in and closes to the stator. The electric drive module is compact and space saving, the flexible gear is secured to the housing, the rotation of the rigid gear driven by the deformation of the flexible outputs power, which is low rotational inertia and decreases vibration, the cooling pipe arranged in the stator can directly dissipate heat from the stator with high heat dissipation efficiency.

Abstract: The present invention discloses an apparatus, a system and a method for short-range sound wave communication. The system realizes non-contact secure transmission by using the sound wave as the data transmission medium, and also can realize a reliable and secure data link directly through an audio connection. The invention systematically constructs multiple end-to-end transmission verification mechanisms for the process of data transmission: transmission data integrity verification, valid time verification, password verification, service data verification and data encryption; and according to the security level of the data, the sending end specifies the requirements for encryption and data verification in the transmission data so as to notify the reception end which verifications should be performed to the data packets, how to perform the verifications, etc. By using the same verification processing manner, operations can be performed to the data (e.g. the payment and settlement function of an account).
