摘要： The present invention provides a bone conduction microphone including a housing and a circuit board connected with the housing. The circuit board has an acoustic channel. The microphone further includes a vibration assembly forming a first conduction cavity and a second conduction cavity. The vibration assembly includes a vibration member and a frame. The frame, the vibration member and the circuit board form a first conduction cavity. The frame, the vibration member and the circuit board form a second conduction cavity. The vibration of the vibration member is conducted to one side of the vibration diaphragm, and is also conducted to the other side of the vibration diaphragm. Compared with the related art, the bone conduction microphone of the present invention can effectively improve the sensitivity and the signal to noise ratio.

摘要： The present disclosure relates to a vehicle-mounted woofer device and a design method therefor. The vehicle-mounted woofer device comprises a box body and a woofer disposed in the box body. The woofer comprises a cone. The cone has a front surface facing the interior of a cabin and a rear surface opposite to the front surface. A cavity is formed between the rear surface of the cone and the box body. A main waveguide for communicating the cavity with the outside is disposed in the box body. A secondary waveguide is further disposed in the box body. The main waveguide and the secondary waveguide are each provided with an inlet in communication with the cavity. The main waveguide is provided with an outlet for communicating with the outside of the cabin, and the secondary waveguide is provided with an outlet for communicating with the outside or inside of the cabin. The woofer device of the present disclosure has high sensitivity and relatively obvious low-frequency expansion, and improves the sound pressure level at low frequencies. According to the design method of the present disclosure, more parameters can be adjusted and controlled, and the degree of freedom is greater.

摘要： A transportation vehicle provides a workspace in a passenger cabin to support a teleconference with a remote party. External sensors are configured to scan the exterior of the vehicle. A sound exciter is configured to generate a masking noise directed to the exterior. A control circuit which enhances privacy of the teleconference is configured to A) detect the audio content of the teleconference being present in the interior of the vehicle, B) quantify an interior sound level of the audio content, C) estimate a discernability of the audio content at an external location accessible to passersby where the audio content can be overheard, and D) activate the sound exciter such that the masking noise is adapted to mask the audio content at the external location.
