Embodiment Construction

[0017] Hereinafter, further description will be made with reference to the drawings and the embodiments.

[0018] FIG. 1 is a schematic structural diagram of a mobile phone 100 as an example in an embodiment of a mobile electronic device of the present invention. The mobile phone 100 includes a phone casing 10 having a substantially rectangular parallelepiped structure. The bottom area of ​​the phone casing 10 forms a key area 11, the central area forms a display area 12, and the top end forms a sounding area 13. A sound hole 132 is provided on the side wall of the sound area 13.

[0019] 1 and 2, the inside of the phone housing 10 is provided with a speaker structure 20 at a position corresponding to the sounding area 13 of the mobile phone 100. 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 sound box housing 60, and the frame body 40 is sandwiched between the sound box housing 60 and the c...

Abstract

A sound box structure comprises a sound box shell and a loud speaker arranged therein. A front sound chamber and a rear sound chamber are formed in the sound box shell. The loud speaker is arranged between the front and the rear sound chambers. A sound output hole is disposed on the front sound chamber for communicating with the outside. The front and the rear sound chambers are communicated by a sound guide pipe. The sound box shell is formed by inclosing a base plate and side plates and a retaining space is formed in the sound box shell. A ring wall connected to the base plate and a baffle for connecting the ring wall with the side plates are arranged in the retaining space. The loud speaker is in the ring wall and a first and a second cavities are formed by separating the ring wall inner area through the loud speaker. A third and a fourth cavities are formed by separating the area between the ring wall and the side plates through the baffle. The front sound box is formed by communicating the first and the third cavities and the rear sound box is formed by communicating the second and the fourth cavities. The sound box structure can promote vocalization quality of the loud speaker. The invention also relates to a mobile electronic equipment that is provided with 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 telephones and personal digital assistants (PDAs) has greatly increased. 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 used to convert sound signals into electrical signals, or electrical signals are converted into structural vibrations to produce sound. Among them, the widely used electro-acoustic conversion element that converts electrical signals into sound is a Loudspeaker. [0003] In recent years, as mobile phones continue to develop in the direction of lightness, thinness and shortness, the size of speakers used in mobile phones has also been limited. In order...
