Improved structure of Bluetooth speakers

Abstract

An improved structure for a Bluetooth speaker mainly comprises a cabinet, two mid-bass speakers and a tweeter housed inside the cabinet, and a power amplifier circuit connecting the two mid-bass speakers and the tweeter. The front of the cabinet is curved, and the two mid-bass speakers are positioned at an angle from the front to the sides along the inner edge of this curved surface, thus positioning the mid-bass speakers of the left and right channels at an angle on the left and right sides. The tweeter is located at the front or rear edge of the center of the cabinet and consists of a drive circuit and a metal diaphragm. This allows the two channels of the Bluetooth speaker's two mid-bass speakers to achieve a 30-45 degree separation, significantly improving the immersive stereo sound effect. Furthermore, because the tweeter directly drives the metal diaphragm to generate audio, its output frequency is more delicate, clear, and crisp, and its audio efficiency range is wider and higher.

Claims

1. An improved structure for a Bluetooth speaker, comprising a cabinet and two mid-bass speakers and a tweeter disposed inside the cabinet, and a power amplifier circuit connecting the two mid-bass speakers and the tweeter, wherein, The two mid-bass speakers are positioned at an angle from the front edge to the sides of the cabinet, thus placing the two mid-bass speakers of the left and right channels diagonally on the left and right sides of the cabinet, creating a 30-45 degree separation sound effect. The tweeter is located at the front or rear edge of the center of the cabinet and consists of a drive circuit and a metal diaphragm. This enhances the stereo sound effect of the Bluetooth speaker, and because the tweeter directly drives the metal diaphragm to generate audio, its output sound frequency is more delicate, clear, and crisp, and its audio efficiency range is wider and higher.

2. An improved structure for a Bluetooth speaker as described in claim 1, wherein, The front of the enclosure is curved, and the two mid-bass speakers are positioned at an angle from the front edge to the sides on the inner edge of the curved surface.

3. An improved structure for a Bluetooth speaker as described in claim 1, wherein, The rear edge of the enclosure is equipped with an external speaker connector and a switch. The external speaker connector is for connecting external floor-standing or desktop speakers. By utilizing the new electronic technology of the power amplifier circuit, the 3.7V-5W power amplifier is activated when the switch is switched to the external floor-standing or desktop speaker. The power amplifier circuit is then switched to an artificial intelligence electronic analog amplifier circuit (AI), and the power is amplified to approximately 60W for playback on the floor-standing or desktop speaker.
