Description

Loudspeaker Base Construction

technical field

The invention relates to a base structure of a loudspeaker, especially a base capable of air convection inside the loudspeaker and rapid heat dissipation, so as to achieve the purpose of rapid heat dissipation of the loudspeaker and excellent sound quality.

Background technique

The loudspeaker is generally called the horn, which is a converter that converts radio signals into sound waves and then transmits them. Various electronic products such as broadcasting, audio, television, computers, audio-visual equipment, etc. that need to sound must pass through speakers. The sound effect is transmitted, and the speaker uses the voice coil to be placed in the magnetic body, and the magnetic induction is generated after the voice coil is energized, and the voice coil is reciprocated with the magnetic body as the axis, that is, the voice coil vibrates back and forth to generate sound waves of different frequencies. Then it is transmitted through the speaker, which becomes different high and low sound effects; and the speaker currently used, such as the new patent of "full cover metal drum paper horn combination structure" filed by the inventor on June 20, 2000 , Application No. 89210563, announced in the TW Patent Gazette on November 21, 2000, and announced No. 465898, which is in body A (please refer to shown in Figure 5) The metal drum paper B is installed on the sound cover A1 of the drum paper B, and the post B1 formed by the bottom edge of the drum paper B is surrounded by a voice coil B2 around the periphery, and the drum paper B is fixed through the soft fixing ring C and the pressure ring D. It is connected and closed with the opening of the front edge of the sound cover A1, and a convex arc-shaped arc C1 is provided in the center of the fixing ring C, so that the drum paper B will not break when it is affected by sound waves, and the drum paper B is also properly deformed when it is heated. In addition, the sound chamber A11 between the drum paper B and the sound cover A1 is provided with an elastic wave E, and the elastic wave E is tightly covered on the edge of the post B1 of the drum paper B, so that the elastic wave can be The sound waves generated by E are effectively transmitted, and a ring F is added at the top edge of the drum paper B to integrate with the tweeter B11 in the central post B1 of the drum paper B.

However, the above-mentioned existing loudspeakers, due to the lack of structural design, will produce the following deficiencies when used, for example:

1. When the voice coil B2 of the drum paper B generates sound wave vibration in the body A due to magnetic induction, even if the internal temperature of the sound chamber A11 rises and heats up, it only uses the drum paper B for heat dissipation, and cannot dissipate the heat source inside the sound chamber A11. Rapid removal, poor heat dissipation effect.

2. The sound chamber A11 is in a completely closed state. Therefore, when the elastic wave E vibrates and transmits sound waves, it is easy to circulate the airflow inside the sound chamber A11, thereby generating resonance noise, and the noise cannot be quickly eliminated by the drum paper B. Remains in the sound chamber A11 and affects the quality of the sound waves.

Please also refer to Figure 6, which is a perspective view of the back of another existing speaker. The speaker is provided with several cooling holes G11 on the outer edge of the bottom G1 of the main body G to dissipate the heat generated by the main body G. However, due to the cooling holes G11 is located at the bottom G1 and is restricted by the rib G2. If the cooling hole G11 is placed on the rib G2, the strength of the rib G2 will be damaged. The cooling hole G11 must avoid the rib G2, and the heat dissipation cannot be expanded or lengthened. The aperture of the hole G11 can only be set in a limited space, so the aperture of the heat dissipation hole G11 is small, the heat dissipation effect is not good, and the air inside the main body G cannot convect with the outside world, so that the inside of the main body G is easy to accumulate sound vibrations. The noise generated will directly affect the quality of the sound delivered by the speaker.

And above-mentioned existing loudspeaker, because of its structure or the design of device, so that there are many deficiencies in implementation, really need to be improved, and this is the direction that the inventor and those engaged in this industry want to improve urgently.
