Full-band high-tone-quality electronic product loudspeaker with sound beam and sound tunnel

Abstract

The invention discloses a full-band high-tone-quality electronic product loudspeaker with a sound beam and a sound tunnel. The full-band high-tone-quality electronic product loudspeaker comprises a voice coil, a metal plate, a vibrating diaphragm and a magnetic conduction structure, the diaphragm is annular, the outer edge of the diaphragm is combined with the loudspeaker outer frame, the inner edge of the diaphragm is combined with the periphery of the metal plate, and the middle of the metal plate corresponds to the upper end of the voice coil; a bridge type sound beam is arranged on the vibrating diaphragm, is annularly erected on the upper surface of the inner edge of the vibrating diaphragm, and is positioned on the outer side of the metal plate in the horizontal direction of the loudspeaker; the upper surface of the vibrating diaphragm is provided with four grooves which equally divide the surface of the vibrating diaphragm at the outer side of the bridge-type sound beam into four resonance areas. And each groove transversely penetrates through the bridge type sound beam and is concavely arranged on the upper surface of the vibrating diaphragm to form a sound tunnel. According to the invention, the diaphragm is changed from a free vibration mode to a standard vibration mode, the problems that the high-pitch area of the loudspeaker of an electronic product cannot be high and nice while the low-pitch area is not deep and mellow are solved from the aspects of vibration, resonance and sound production, and practice proves that the improved scheme has outstanding substantive features and remarkable technical progress. And an obvious technical effect is achieved.

Description

technical field [0001] The invention relates to a loudspeaker, in particular to a full-frequency high-quality electronic product loudspeaker with a sound beam and a sound tunnel. The electronic product loudspeaker can be applied to electronic products such as earphones, headsets, mobile phones, tablet computers, and notebook computers. Background technique [0002] A loudspeaker (also known as a horn) is a device that converts electrical signals into acoustic signals, such as figure 1 , 2 As mentioned above, a traditional speaker for an electronic product is usually composed of a voice coil 1, a metal plate 2, a diaphragm 3, a magnet, and a magnetically conductive structure (not shown in the figure). When the speaker is working, the currents output by the amplifier are converted into sound waves through frequency waves, and the output energy is increased through the promotion of power, and the voice coil 1 is moved under the action of the magnetic field, and the voice coil ...

Problems solved by technology

[0003] The common problem of traditional speakers of electronic products is that there is an inherent resonant frequency when the speaker produces sound. After exceeding a certain range of the resonant frequency area, the high-pitched area cannot be bright, and the low-pitched area is not thick and mellow enough.

Bass must be achieved through a dedicated woofer, and treble must be achieved through a dedicated tweeter, that is, the timbre is proportional to the number of speakers, and it is impossible to achieve full-range high-quality timbre through a single speaker

The main reason is that the current loudspeaker diaphragm cannot meet the good broadband vibration from the high-pitched range to the low-pitched range, that is, it cannot adapt to the resonance and vibration of the wide-ranging frequency changes in the high-pitched, mid-range, and low-pitched ranges at the same time.

To sum up, the structural design of traditional speakers for electronic products is unreasonable, which is not conducive to the good sound wave vibration of the diaphragm from the high-pitched range to the low-pitched range.

To achieve appreciative-level sound quality performance, multiple speakers with different frequency bands need to be combined, and this is usually expensive, which is not conducive to expanding the market. In addition, the volume is usually large and requires more placement space, which is not conducive to the development of electronic products. Thinning
