Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0023] The speakers of the terminal equipment include full-cavity BOX speakers and half-cavity BOX speakers. The full-cavity BOX speaker is integrally packaged to form the sound cavity of the speaker, and the sound quality is good. However, the structural design and processing technology of the full-cavity BOX speaker are complicated, the cost is high, and the individual occupies a large space, so it is difficult to combine and install with other structures in the terminal equipment. The half-cavity BOX speaker can use the shell of the terminal device to package the sound ...

Abstract

The invention discloses a terminal device. The terminal equipment comprises a first shell, a second shell, a first spacer, a mounting plate and a loudspeaker, the first shell and the second shell jointly define a containing space, at least one mounting cavity communicated with the containing space is formed in the first shell and / or the second shell, the first spacer at least partially surrounds the periphery of the loudspeaker, and the mounting plate is arranged in the containing space. The first spacer, the mounting plate, the first shell and / or the second shell jointly define a rear sound cavity of the loudspeaker, and the rear sound cavity is communicated with at least one mounting cavity. The audio emitted by the loudspeaker can enter the mounting cavity through the rear sound cavity, and the rear sound cavity and the mounting cavity are jointly used for audio transmission, so that the terminal equipment can obtain a larger audio transmission space, and the tone quality of the terminal equipment is improved. The mounting cavity on the shell assembly is the original space in the terminal equipment, so that the volume of the space for audio transmission at the rear sound cavity can be enlarged without planning other spaces, and the light and thin design of the terminal equipment is facilitated.

Description

technical field [0001] The present application relates to the technical field of electroacoustic products, and in particular to a terminal device. Background technique [0002] With the rapid development of electronic technology, portable terminal equipment is becoming more and more miniaturized, and the requirements for the size and sound quality of electroacoustic devices of terminal equipment are also getting higher and higher. The speaker is an important acoustic component of the portable terminal equipment, which is used to complete the conversion of electrical signals and acoustic signals. Among them, the use of dual speakers in terminal equipment is becoming more and more popular. The sound cavity of the dual speakers is divided into a front sound cavity and a rear sound cavity. The front sound cavity and the rear sound cavity are completely separated, and the volume of the rear sound cavity determines The resonant frequency of the electroacoustic device is determine...
