The embodiment of the utility model provides loudness testing equipment of a recorder. Relates to the testing field. The loudness testing equipment of the recorder comprises a sound production device, a sound receiving device and processing equipment, the sound production device comprises an audio analyzer and an artificial mouth, and the audio analyzer is connected with the artificial mouth; the sound receiving device comprises a microphone and a sound card, the microphone is connected with the sound card, and the sound card is connected with the processing equipment; the audio analyzer is used for controlling the artificial mouth to play a first sound signal, the recorder is used for collecting and processing the first sound signal to obtain a second sound signal and playing the second sound signal, and the microphone is used for collecting and processing the second sound signal to obtain a third sound signal and sending the third sound signal to the processing equipment through the sound card; and the processing equipment is used for determining a loudness test result of the recorder according to the third sound signal. And the accuracy of the loudness test of the recorder is improved.

A method, an apparatus and a system for testing a bone conduction communication device is disclosed. A vibration exciter is disposed at a wearing position of an artificial head model where the bone conduction communication device is located. The method comprises: transmitting a test audio to first and a second digital signal processors; transmitting an audio signal processed by the first digital signal processor to the vibration exciter, and simulating vibration of a bone at a corresponding part by which human generates sound using the vibration exciter, to generate a vibration signal; transmitting an audio signal processed by the second digital signal processor to an artificial mouth and simulating human sound production to generate an acoustic signal; collecting the vibration signal and the sound signal using the bone conduction communication device, and testing the bone conduction communication device according to the collected vibration signal and sound signal.

The invention belongs to the technical field of cigarette tipping paper taste substance analysis, and particularly relates to a bionic simulation collection device and an analysis method for the dynamic migration quantity of taste substances in taste tipping paper. The bionic simulation collection device comprises a simulation lip, a simulation oral cavity, a smoke collector and a smoke suction machine which are sequentially communicated from upstream to downstream. The analysis method comprises the following steps: S1, connecting an artificial lip and a simulated oral cavity with a smoking machine, and infiltrating with artificial saliva; s2, the taste tipping paper of the cigarette is fixed to an artificial lip, the surface of the artificial lip is attached to the surface of a filter tip, and in the smoking interval process, the cigarette is inserted and pulled out; s3, after smoking is finished, the artificial lip cleaning fluid and the simulated oral cavity cleaning fluid are collected, and the migration amount of the taste substances is detected. The method is closer to the actual cigarette smoking process, and powerful technical support can be provided for cigarette product research and development, smoke physiological feeling, smoking, health and other basic research.

The application discloses a kind of intelligent cockpit voice visible can say automation test method and system, belong to automobile technical field, comprising: according to voice visible can say use scene and write test case;Test case is generated robot file and resource file by Python script, and the voice parameter required in resource file is configured in test scene;Judge whether the execution visible can say test case is dynamic name;Tactics, voice configuration parameter is input into speech synthesis model to generate wav audio file;Audio file is played by acoustic dummy-artificial mouth;Vehicle machine log and RF script assertion are grabbed by ADB command, and the vehicle machine log and RF script assertion are compared and verified;Test report is automatically generated by RF framework.The method designs test set according to visible can say use scene and process, can improve the coverage of test case, simulates intelligent cockpit user real use scene to the greatest extent.
