Embodiment 1

[0023] This embodiment provides a speaker, and the speaker can be applied to a terminal, where the terminal can be a smart phone, a tablet computer, or other devices.

[0024] Dynamic speakers are widely used in terminals to convert audio electrical signals generated by the terminal into sound wave signals, thereby generating sound. The core part of the dynamic speaker is the voice coil and diaphragm. The voice coil is placed in a magnetic field. When the audio electrical signal generated in the terminal flows through the voice coil, the voice coil will vibrate under the action of magnetic field force (ie Lorentz force) in the magnetic field. The diaphragm connected to the voice coil then vibrates, and drives the air around the diaphragm to vibrate, thereby producing sound.

[0025] refer to figure 1 , figure 1 Shown is a cross-sectional view of the speaker provided by the embodiment of the present invention.

[0026] The loudspeaker 10 includes a bracket 11 , an upper co...

Embodiment 2

[0042] This embodiment provides a speaker, and the speaker can be applied to a terminal, where the terminal can be a smart phone, a tablet computer, or other devices.

[0043] refer to Figure 4 , Figure 4 Shown is a cross-sectional view of the speaker provided by the embodiment of the present invention.

[0044] The loudspeaker 20 includes a bracket 21 , an upper cover 22 , a hearing aid coil 23 , a fixed layer 24 , a magnetically conductive plate 25 , a magnetic steel 26 , a magnetically conductive sheet 27 , a voice coil 28 and a diaphragm 29 .

[0045] Wherein, the upper cover 22 is installed on the bracket 21 . In a specific application, the upper cover 22 may be fixed on the bracket 21 by bonding. The bracket 21 can be integrally formed by injection molding. The upper cover 22 can also be integrally formed by injection molding. In a preferred embodiment, the bracket 21 and the upper cover 22 are made of nanomaterials. Both the bracket 21 and the upper cover 22 are...

Abstract

The embodiment of the invention provides a loudspeaker. The loudspeaker comprises a hearing-aid coil and a bracket, the bracket is provided with a sunken part, the hearing-aid coil is installed in the sunken part. Through the adoption of the scheme, the hearing-aid coil is installed in the sunken part on the bracket, so that the hearing-aid coil does not occupy the extra space, the thickness of the loudspeaker cannot be increased. Compared with the prior art, the thickness of the loudspeaker can be reduced, the thinning of the terminal of the loudspeaker is facilitated.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a loudspeaker and a terminal. Background technique [0002] The loudspeaker is an important part of the terminal equipment, and it is an energy conversion device, which is usually used to complete the conversion between electrical signals and sound signals. A common loudspeaker includes a housing in which a magnetic circuit part and a vibrating part are accommodated. The magnetic circuit part provides a magnetic field for the vibrating part. The vibrating part includes a voice coil and a diaphragm. When the audio electrical signal generated in the terminal flows through the voice coil, the voice coil drives the diaphragm to vibrate in the magnetic field, thereby producing sound. [0003] At the same time, the number of users using hearing aids is increasing. When these users use terminals equipped with ordinary speakers, the hearing aids will produce howling and can...
