Problems solved by technology

Traditional loudspeakers rely on traditional microphones to convert sound signals into electromagnetic signals. This method of signal collection is very convenient. The signal is collected through air transmission, but it is easily disturbed by the external environment, especially the interference of airflow.

Abstract

The invention discloses a loudspeaker for an automobile. The loudspeaker comprises a microphone, a signal processing and emitting device, and a throat microphone installed near the throat of a user. The throat microphone and the microphone are connected through a lead. The microphone and the signal processing and emitting device are connected through a lead. The signal processing and emitting device comprises an antenna disposed on the top of the signal processing and emitting device, and also an electromagnetic signal converter, a signal amplifier, a frequency tuning part and a loudspeaker assembly that are disposed inside the signal processing and emitting device. The signal processing and emitting device is equipped with a display screen. The signal processing and emitting device is equipped with a frequency adjusting turn button and a volume adjusting turn button. The signal processing and emitting device is powered by two 1.5v dry cells inside the signal processing and emitting device. The loudspeaker is reasonable in design and simple in structure, is convenient to use, and is suitable for places such as offices and classrooms.

Description

technical field [0001] The invention relates to the technical field of loudspeaker preparation, in particular to a loudspeaker for automobiles. Background technique [0002] A loudspeaker is a device that converts human voice or other sounds into signals to achieve high power output and increase the volume. At present, loudspeakers are divided into wired type and wireless type according to the way of sending signals, and small and large according to volume. Generally, there are those powered by dry batteries, some powered by lithium-ion batteries, and of course external power supplies. Loudspeakers are mainly used for teaching, tour guides, and outdoor activities. Traditional loudspeakers rely on traditional microphones to convert sound signals into electromagnetic signals. This method of signal collection is very convenient. The signal is collected through the air, but it is easily disturbed by the external environment, especially the airflow.
