Abstract

The utility model provides a sounding pointer, comprising a pointer rod and a handle disposed on root of the pointer rod. The pointer rod is an expansion rod. Batteries, a language integrated module, and a small power amplifier are disposed in the handle. Buttons are disposed on a surface of the handle. A loudspeaker is fixed on a back of the handle. The language integrated module and the small power amplifier are electrically connected. The small power amplifier and the loudspeaker are electrically connected. The language integrated module is electrically connected with the batteries through the buttons. The batteries are respectively electrically connected with the small power amplifier and the loudspeaker. The sounding pointer is simple in structure, low in cost, strong in interestingness, and is a novel teaching appliance which can train students' scientific consciousness, innovative thinking and operational ability.

Description

A kind of sounding pointer

Technical field

Utility model relates to a kind of sounding pointer.

Background technology

Teacher's pointer is a kind of aid of teachers ' classroom teaching, and form is varied, and Telescopic pointer is more common, but does not possess vocal function, and function singleness is interesting poor.

The utility model content

The purpose of this utility model provides a kind of sounding pointer, can not sounding to overcome existing teacher's pointer, interesting poor defective.

For reaching above-mentioned purpose, the utility model has supplied a kind of sounding pointer, comprises whip bar and the handle that is arranged on this whip pole-footing section, and described whip bar is an expansion link; Battery, language integrated package and small power amplifier are housed in the described handle, handle surfaces is installed button, a loudspeaker is fixed at the handle back, the language integrated package is electrically connected with small power amplifier, this small power amplifier is electrically connected with loudspeaker, the language integrated package is electrically connected with battery by button, and battery is electrically connected with small power amplifier, loudspeaker respectively.

Above-mentioned button is two.

Above-mentioned expansion link is by a root pole and a plurality ofly consist of from this pole that root pole connects together successively, external diameter reduces successively;

This root pole is the cylinder bar that an opening part is provided with annular retaining ring;

The external diameter of this pole is provided with the card that stops that pole skids off from annular retaining ring less than the internal diameter of described annular retaining ring on the inner outer wall of this pole.

The utility model has the advantages that: simple in structure, with low cost, interesting strong, be a kind of new teaching apparatus, can cultivate student's scientific consciousness, innovative thinking and manipulative ability.

Below with reference to accompanying drawing the utility model is described in further details.

Description of drawings

Fig. 1 is the structural representation of sounding pointer.

Fig. 2 is the structural representation of laser pen receiving unit.

Among the figure: 1, whip bar; 2, handle; 3, key one; 4, key two; 5, root pole; 6, pole; 7, opening; 8, annular retaining ring; 9, card.

Embodiment

Can not sounding in order to overcome existing teacher's pointer, interesting poor defective, present embodiment provides a kind of sounding pointer shown in Figure 1, comprises whip bar 1 and is arranged on the handle 2 of this whip bar 1 root, described whip bar 1 is an expansion link; Battery, language integrated package and small power amplifier are housed in the handle 2,

button

3,4 is installed on handle 2 surfaces, a loudspeaker is fixed at handle 2 backs, the language integrated package is electrically connected with small power amplifier, this small power amplifier is electrically connected with loudspeaker, the language integrated package is electrically connected with battery by button, and battery is electrically connected with small power amplifier, loudspeaker respectively.

Referring to Fig. 2, the expansion link that consists of teacher's pointer whip bar 1 is by a root pole 5 and a plurality ofly consist of (only illustrated among this figure a pole) from this pole that root pole 5 connects together successively, external diameter reduces successively 6;

Figure is not difficult to find out thus, and this root pole 5 is cylinder bars that an opening 7 places are provided with annular retaining ring 8.

The external diameter of pole 6 is provided with the card 9 that stops that pole 6 skids off from annular retaining ring 8 less than the internal diameter of annular retaining ring 8 on the inner outer wall of this pole 6.

More than exemplifying only is to illustrate of the present utility model, does not consist of the restriction to protection domain of the present utility model, and the every and same or analogous design of the utility model all belongs within the protection domain of the present utility model.
