Embodiment Construction

[0017] Further description will be made below in conjunction with the embodiments with reference to the accompanying drawings.

[0018] figure 1 Shown is a schematic structural diagram of one embodiment of the mobile electronic device of the present invention, taking the mobile phone 100 as an example. The mobile phone 100 includes a phone case 10 , which is roughly in the shape of a cuboid. The bottom area of ​​the phone case 10 forms a keypad 11 , the central area forms a display area 12 , and the top forms a sounding area 13 . A sound hole 132 is formed on the side wall of the sound emitting area 13 .

[0019] Please refer to figure 1 and figure 2 A speaker structure 20 is provided inside the phone casing 10 at a position corresponding to the sound emitting area 13 of the mobile phone 100 , and the speaker structure 20 includes a circuit board 30 , a frame 40 , a speaker 50 and a speaker housing 60 . The speaker 50 is placed in the speaker casing 60 , and the frame 40 ...

Abstract

The present invention discloses a sound box structure, comprising a sound box housing and a loudspeaker arranged inside the sound box housing, which is characterized in that a front sound chamber and a rear sound chamber are formed inside the sound box housing; a sound outlet bore arranged on the front sound chamber is communicated with the outside; at least one clapboard is arranged between the front sound chamber and the rear sound chamber; the loudspeaker is arranged between the front sound chamber and the rear sound chamber; the front sound chamber is communicated with the rear sound chamber through a sound guiding bore arranged on the clapboard; a receiving space is formed in the sound box housing, a ring wall is arranged in the receiving space, a first cavity and a second cavity are formed through the separation of the loudspeaker in the ring wall by the loudspeaker, a third cavity and a fourth cavity is formed between the ring wall and a side plate by the clapboard; the first cavity is communicated with the third cavity to form the front sound chamber, the second cavity is communicated with the fourth cavity to form the rear sound chamber. The sound box structure is capable of enhancing the sound quality of loudspeakers. The invention further relates to a mobile electronic device having the sound box structure.

Description

technical field [0001] The invention relates to a sound box structure, in particular to a sound box structure of a mobile electronic device. Background technique [0002] With the rapid development of the information industry, the demand for mobile electronic devices such as mobile phones (Mobile telephone) and personal digital assistants (PDA) has increased greatly. As a communication tool for people, the most basic function of mobile phones is to transmit sound signals. In order to transmit sound signals, electro-acoustic conversion elements are needed to convert sound signals into electrical signals, or convert electrical signals into structural vibrations to generate sound. Among them, the widely used electro-acoustic conversion element for converting electrical signals into sound is a loudspeaker. [0003] In recent years, due to the continuous development of mobile phones in the direction of thinner, lighter and smaller, the size of speakers used in mobile phones is a...
