摘要： A speaker comprises a housing, a transducer residing inside the housing, and at least one sound guiding hole located on the housing. The transducer generates vibrations. The vibrations produce a sound wave inside the housing and cause a leaked sound wave spreading outside the housing from a portion of the housing. The at least one sound guiding hole guides the sound wave inside the housing through the at least one sound guiding hole to an outside of the housing. The guided sound wave interferes with the leaked sound wave in a target region. The interference at a specific frequency relates to a distance between the at least one sound guiding hole and the portion of the housing.

摘要： A bone conduction speaker includes a housing, a vibration board and a transducer. The transducer is located in the housing, and the vibration board is configured to contact with skin and pass vibration. At least one sound guiding hole is set on at least one portion of the housing to guide sound wave inside the housing to the outside of the housing. The guided sound wave interfaces with the leaked sound wave, and the interfacing reduces a sound pressure level of at least a portion of the leaked sound wave. A frequency of the at least a portion of the leaked sound wave is lower than 4000 Hz.

摘要： A sound source device of a horn according to one aspect of the present invention includes: a diaphragm; a movable iron core connected to the diaphragm through a support point; and a coil (bobbin and winding) into which a driving signal is inputted. The driving signal includes a first signal component that resonates with the diaphragm and a second signal component of a second frequency that resonates with the movable iron core of a first frequency and has a chord relationship with the first frequency. The support point is provided at a position eccentric from the center of the diaphragm, and the movable iron core is structured such that a gravity center is displaced further in an eccentric direction than the support point.

摘要： A vehicle approach alert device includes: a microcomputer having a memory that stores approach alert sound data, and a signal generator that generates an approach alert sound voltage waveform signal based on the approach alert sound data. The vehicle approach alert device alerts approach of a vehicle by outputting a vehicle approach alert sound from a sound outputting body according to the approach alert sound voltage waveform signal. The microcomputer further includes: an obtaining device that obtains a sound outputting body temperature; and a sound pressure correcting device that corrects a voltage level of the approach alert sound voltage waveform signal to be larger as the sound outputting body temperature increases.

摘要： A vehicle includes a horn assembly disposed behind a grille. The horn assembly includes a coil configured to generate a magnetic field in response to a current, a first diaphragm connected to a first plunger, a second diaphragm connected to a second plunger, and a spring. The spring is connected to the first and second plungers such that oscillation is transferred from the first diaphragm to the second diaphragm through the spring in response to the magnetic field from the coil.
